Cork oak woodlands are socio-ecosystems recognized as biodiversity hotspots, a fundamental economic source for companies and local communities as well as an identitarian landscape for residents and visitors. Cork oak woodlands, however, are facing tree mortality and lack of regeneration. Considering the oak decline scenario, we present Iberian cork oak montado/dehesa as a socio-ecosystem facing climate change, management transformations, local knowledge crisis and social uncertainty. We review montados/dehesas research through time and by different scholar perspectives. We defend that from an interdisciplinary and transdisciplinary perspective, including the experience and evidence observed in terrain, debate should be stimulated, and novel conceptual approaches may contribute to finding solutions. We argue that the confluence of ecology, genetics, anthropology and local knowledge can be explored to unveil the complexities and the challenges of these socio-ecosystems and contribute to prevent and mitigate threats to it. We propose a methodological approach built together with scientists, managers and workers, that can explore oak translocations, socio-ecological interactions models, knowledge transfer and other ways to overcome Iberian cork oak woodlands socio-environmental crisis.

Climate changes comprise increasing global temperature and water cycle deregulation (precipitation storms and long dry seasons). Many affected ecosystems are located within the Mediterranean basin, where cork oak (Quercus suber L.) is one of the most important forest ecosystems. Despite cork oak tolerance to drought, the decrease of water availability and increase of temperature is causing a serious decline of cork oak populations. In the present work, the bacterial community of cork oak soils was assessed by metabarcoding using Illumina Miseq. Soils from seven independent cork oak forests were collected along a climate gradient. In all forest soils, Proteobacteria and Actinobacteria were the richest and more abundant bacteria. Acidobacteria also presented a high relative abundance, and Chloroflexi was a rich phylum. The soil bacterial community diversity and composition was strongly affected by the climatic region where cork oak resides and specific bacterial taxa were differently affected by precipitation and temperature. Accordingly, cork oak bacterial communities clustered into three distinct groups, related with humid, sub-humid and arid/semi-arid climates. Driest and warmer forests presented more diverse bacterial communities than humid and coolest forests. However, driest climates presented more homogenous bacterial communities among forests than humid climates. Climate (mainly precipitation) revealed to be the strongest driver leading to significant variations of bacterial community profiles. The most impacted bacterial taxa by climatic variables were Proteobacteria, in particular Gammaproteobacteria and Deltaproteobacteria, Chloroflexi, and Firmicutes. Humid forests presented mainly Acidobacteria as good indicators of climate, whereas Actinobacteria members were better indicators for arid forests (mainly Gaiellales and Frankiales). Some indicator species for different climate conditions were members of the bacterial core of cork oak stands (7% of the total bacterial community). Taken together, different microbiomes were selected by the climate conditions in cork oak stands along a climate gradient and might provide the key to forest sustainability in times of global warming.

UID/LIN/03213/2013 PD/BD/113972/2015Within the scope of the TermCork project, we intend to explore the contribution of texts for conceptually based terminological work. Given that texts are vehicles for knowledge transfer, they should be processed according to their original purpose, namely the verbal transmission of knowledge in a context of specialized communication.Going beyond this function implies looking at texts from a different angle. Based on the double dimension of Terminology, this paper targets the analysis of texts for onomasiological ends, focusing on the analysis of intensional and contextual definitions aiming at identifying information and knowledge that will allow us to make lexical maps on the one hand, and conceptual maps on the other. Definitions are thusat the core of this study. The linguistic analysis we undertook over definitions in natural language will demonstrate that different levels of analysis can be performed given the different semantic information c...

Materials based on graphitic carbon are used for environmental remediation, due to their high surface area and their capacity to adsorb pollutants in liquid environments. Carbonaceous materials derived from residues are particularly interesting, as their synthesis has a smaller impact on the environment. In the present work, we report a preliminary study on the preparation of graphitic carbon made from cork waste powder modified with magnetic nanoparticles (MNPs). This is the first time such composites were prepared using pyrolysed/carbonised cork, from a powder residue of cork stopper production. This makes the process sustainable and in line with the circular economy. The composites were prepared by vacuum infiltration of the MNPs on pyrolysed cork powder, with a successive thermal treatment, resulting in a carbon material that retained the porous microstructure of the original cork, ideal for the absorption of pollutants or separation of oils and water, while also being magnetically separable afterwards. It was seen that post-infiltration heating was better in air than under nitrogen, with the nitrogen atmosphere and presence of highly porous carbon possibly partially reducing magnetite to FeO, with a reduction in magnetic properties. MNPs with different chemical compositions were tested – zinc ferrite (ZnFe2O4) and magnetite (Fe3O4) – with the magnetite composites showing the highest magnetisation. Moreover, magnetite particles of different dimensions were considered: 6, 9 and 15 nm; results indicated that the 9 nm magnetite NPs were the most easily infiltrated; the magnetisation, however, was higher for the composites with the 15 nm magnetite NPs (about 9 emu g−1), despite the oxide component comprising only around 12 wt% of the composite, due to their greater initial magnetisation. This value is higher than those of similar composites prepared using carbon from other natural sources. SEM analysis showed the presence of MNPs on the surface of the material, with the particles being on the nanometric scale and showing no aggregation on the micron scale. Composites prepared with these 15 nm MNPs also showed greater stability in both water and an organic solvent (chloroform) and were demonstrated to be magnetically separable from suspensions, making them the most suitable for environmental remediation applications.

Arnau Puig és un home d'acció que mai no s'ha fet escàpol de la realitat que li ha tocat de viure. Aquesta afirmació que pot semblar una obvietat, atès que aparentment sembla que tots vivim el nostre temps, no ho és pas, car una cosa és viure i, l'altra, sobreviure o fins i tot infraviure. Dic això perquè ja des de ben jove concebia la vida com un projecte, justament a conseqüència de la inquietud que provoca a l'home el viure, és a dir, el seu entorn i les circumstàncies específiques que l'afecten. Per aquest motiu, just acabada la guerra i enmig de l'etapa més fosca que ha viscut el nostre país al segle XX, en ple desert sociocultural, Puig, amb el tremp de l'autodidacta, inicià el seu camí sempre preocupat per la incidència social i l'aportació a la col•lectivitat. Integritat individual i, alhora, compromís amb els altres, han distingit des del primer moment la seva trajectòria personal i professional, tot plegat una mateixa cosa. Perquè l'home d'acció és present arreu i indissociable en bocins, car la persona és una i Puig és i ha estat des dels seus anys més tendres un filòsof. Filòsof, per tant, amant de la saviesa. No es tractava d'acumular sabers, sinó coneixement, és a dir, d'utilitzar com a eines la reflexió i el pensament, i també l'anàlisi del passat per construir el futur.

És ben conegut el tòpic que atribueix als valencians una capacitat reduïda d'organització social durable. Segons es diu, fins i tot des d'àmbits cultes assentats en el prestigi que dóna la ciència, l'individualisme, l'espontaneïtat i la inconstància són els estereotips que s'adapten més bé a la nostra manera d'actuar en societat. Així, la facultat de crear associacions amb la finalitat d'una acció comuna no pareix que siga un tret característic del nostre comportament. Tanmateix, la qüestió no és tan senzilla. Allò que sembla ser potser no ho siga del tot o, tot considerant que els discursos sempre són interessats, ens hauríem de preguntar per les raons que fomenten i articulen aquests estereotips (Cucó, 1991). Evidentment, no és la nostra intenció trobar respostes a aquestes preguntes. El que pretén aquest l'article és senzillament donar notícia d'una associació,ja desapareguda, que posseïa certes característiques peculiars. Primer que res, perquè es va produir en un àmbit de poblament poc conegut: I'hàbitat dispers. És a dir, va ser una associació de masovers. A més, va estar vigent pràcticament durant tot el segle, fins que el despoblament general que es va produir als anys seixanta va convertir moltes zones del secà en deserts demogràfics. La seua funció consistia a repartir entre els associats la despesa de medecines d'ús humà que cada família havia fet durant un cert període de temps. La qüestió que considerem més important és que s'hi havia arribat a un grau alt de formalització de l'associació: aplecs periòdics, comptabilitat escrita, que fa pensar que ens trobem amb un grup fortament unit. A la primeria del segle XX, el nombre de persones que vivien als masos que envolten Penyagolosa va arribar al seu màxim. D'aleshores fins als anys seixanta, en què es produeix un abandó pràcticament general dels masos com a residència habitual, la població de l'hàbitat dispers va anar baixant progressivament per efecte de l'emigració. Primer cap als pobles propers i després més lluny, fora de la comarca o del país. A pesar del despoblament progressiu, aquesta zona de muntanya del nord del País Valencià presenta una densitat de població dispersa relativament elevada al llarg del segle. Els masos caracteritzen la forma de vida -i per tant el paisatge-de la gent que els habiten: els masovers i les masoveres. La producció de tipus agropecuari es dedica a l'autoconsum, encara que hi ha casos que se n'ha de desviar part com a pagament als propietaris de les telTes. De totes maneres els excedents són molt reduïts i l'economia s'aproxima prou a l'autarquia. Cal entendre aquesta paraula d'una manera no excessivament estricta. Evidentment hi havia comerç entre els masos o amb els pobles i així es possibilitava l'adquisició de coses absolutament imprescindibles. Tanmateix, l'ús dels diners, encara que necessari, és mínim.

This article examines the dissemination processes and geography of wheat species and varieties in Portugal between the 16th and the 20th centuries. Based on a wide range of sources, from monastic records to official agricultural reports and oral interviews, it is concluded that the conditions that shaped the traditional division between soft varieties in the north and hard varieties in the south had changed by the late 19th century.
At that point, soft landraces thrived in the south, but were soon replaced by improved/ hybridized varieties, many of which were imported. Thus, wheat landraces persisted only in the mountainous peripheral areas, due to the agroecological and socioeconomic context.
It is also emphasized that Portugal did not lag the most central countries in terms of agricultural biotechnology development.

As part of a collaborative project to investigate human impacts on Quercus suber L. (cork oak) forests, five research groups from countries in Europe and North Africa undertook a survey of soil quality (physical properties, potentially toxic elements) at sites in NW Tunisia and NW Sardinia. All groups performed the analysis of soil samples after agreeing prescribed methodologies to ensure harmonisation and the production of a robust and reliable data set. The data produced were compared using basic statistical methods and revealed strong positive correlation despite minor operational variation. The data indicates that inter and intra laboratory variability differed from parameter to parameter and that good agreement was obtained where methodology was common. Collaborative research introduced the need for common communication plans and exchange of information not normally supplied in analytical reporting.

The soil of unmanaged cork oak forests located both in Sardinia and in Tunisia was characterized. Soil samples were collected in both areas at the depth of 0-10 cm, to determine the pedologic characteristics [humidity, pH, total organic carbon (TOC), total nitrogen (N) and texture] and the fungi community. The data were tested for significance with analysis of variance (ANOVA) techniques. The soils of the two studied areas were significantly different as far as pH, TOC % and Sand content are concerned. The texture of Sardinia soil was mainly classified as "sandy-loam" and the Tunisian ones as "sandy-clay-loam". Concerning the fungi community in Sardinia soil, the most frequent fungi genera were Trichoderma, Penicillium and Paecilomyces. In Tunisian soil the dominant genus was Penicillium followed by the genus Aspergillus.

Cork oak forests in the MED region are of critical social and ecological value and under stress from both environmental change and variation in management practice. This study, as part of a NATO Science for Peace project (SfP 981674), evaluated geochemical methods to assess potentially toxic element (PTE) input to field sites from Quercus suber forests in Tabarka (Tunisia) and an experimental control forest managed by ARGIS-Sardega (Italy). Surface and subsurface soil samples were collected from environmentally comparable sites in the two regions. Sites were identified with varied stand and shrub density and characterised for basic soil properties and multi element content. The data were evaluated using principle component analysis (PCA) and soil enrichment factors (SEF). Soils showed chemical variability associated with differences in parent material and the effects of biomass density. Contributions from events such as fire damage, as well as biomass, sea salt and geogenic sources can be identified, and evaluation is enhanced using a combination of assessment methods. Ultimately despite concerns for the regulation of forest activities in the study area, little direct anthropogenic impact was on soil quality.

We investigated whether the performance of cork oak under drought could be improved by colonization with the ectomycorrhizal fungus Pisolithus tinctorius. Results show that inoculation alone had a positive effect on plant height, shoot biomass, shoot basal diameter, and root growth. Under drought, root growth of mycorrhizal plants was significantly increased showing that inoculation was effective in increasing tolerance to drought. In accordance, mycorrhizal plants subjected to drought showed less symptoms of stress when compared to non-mycorrhizal plants, such as lower concentration of soluble sugars and starch, increased ability to maintain fatty acid content and composition, and increased unsaturation level of membrane lipids. After testing some of the mechanisms suggested to contribute to the enhanced tolerance of mycorrhizal plants to drought, we could not find any by which Pisolithus tinctorius could benefit cork oak, at least under the drought conditions imposed in our experiment. Inoculation did not increase photosynthesis under drought, suggesting no effect in sustaining stomatal opening at low soil water content. Similarly, plant water status was not affected by inoculation suggesting that P. tinctorius does not contribute to an increased plant water uptake during drought. Inoculation did increase nitrogen concentration in plants but it was independent of the water status. Furthermore, no significant mycorrhizal effect on drought-induced ROS production or osmotic adjustment was detected, suggesting that these factors are not important for the improved drought tolerance triggered by P. tinctorius.

A importância da floresta como fornecedora de benefícios ambientais, sociais e económicos para os seres humanos é uma realidade consensual na comunidade científica. Por essa razão, a preocupação em melhorar a gestão florestal é cada vez maior e nos últimos anos têm-se desenvolvido ferramentas, como os Sistemas de Apoio à Decisão, para lograr este propósito. Neste trabalho avaliam-se duas ferramentas informáticas para melhorar a gestão florestal em ecossistemas mediterrâneos, através da sua aplicação na região do Nordeste Transmontano de Portugal. Um dos grandes objetivos subjacentes a este trabalho é o de, com base nas ferramentas desenvolvidas, promover o aumento da disponibilização da madeira de forma sustentável na região.

Growing production speed of plastics in municipal solid wastes, industrial wastes of petrochemical complexes and related industries are giving rise to environmental, health and economic problems. Abundance sources of agricultural wastes such as rice husk, bagasse, palm fiber, straw, canola and sawdust having limited practical applications are mostly not recycled and most of them discarded or burnt. By collecting these wastes and processing them we are able to produce products having added-value and consequently reduce environmental pollutions. In this project a combination of rice husk and chitosan nanoparticles were combined and formed as a biopolymer. HDPE and also extrusion in a two-screw extruder are used. After producing the composite, physical and mechanical properties of the composite were studied. Analyzing results showed that 36 wt% rice husk has the maximum tensile strength and similarly by reducing the percentage of rice husk and increasing the percentage of chitosan nanoparticles the tensile strength lowered strongly because rice bran have silica compounds too and reducing the percentage of rice husk make tensile strength lowered , also flexural modulus is increased by increasing percentage rice husk but in samples that nanoparticles were increased and rice husk was decreased, flexural modulus decreased too and flexural strength.

The Moment of Historia e Economia W hen Historia e Economia began, we saw it as a multilingual and multidisciplinary forum for Brazilian and international scholars to express their views on Brazil and the wider world. We felt that Brazil looked too much within itself and failed to compare its experiences with those of others. In the two decades since, the world first continued on its course of globalization and then seemed to reverse itself after a severe financial crisis. Despite steps to close borders taken by many regimes, the need to understand, to cooperate with, and to emulate other countries is ever more evident if this planet as a whole expects to survive. We are committed to studying the societies in which we live and to comparing our experiences with those of others polities. A sabbatical in Europe convinced the editor that most historians remains overly national in their research and much less concerned with comparative aspects than he expected, especially within the scope of the European Union. Originally, this journal focused on Brazil-while encouraging studies on any historical or economic subject. With the co-sponsorship of the Universidad de Extremadura, we have expanded our core interest to include all Portuguese and Spanish speaking societies. We continue to seek articles on other areas; in fact, two of our most significant contributions to date include a comparison of English and French technology at the time of the French Revolution as well as a study of the olive oil trade during the Roman Empire. We continue dedicated to interdisciplinary approaches, principally involving history and economics, but also extending to archaeology, psychology, sociology, and politics, among others. We are pleased to announce that Roberta Barros Meira, after serving as Secretary of this journal almost since its inception, has become the Vice Editor for the Americas in place of Rita Almico who completed her term and returns to the editorial board. Roberta s successor as Secretary is José Francisco Rangel Preciado, of the Universidad de Extremadura, who has already made a great contribution to the journal by taking it through the approval processes of the European academic indices, in collaboration with Vice Editor Francisco Manuel Parejo Murano. Alexandre Ramos continues as our other Secretary. Eduarda Regufe has joined us as Assistant Secretary completing our editorial team.

Cork oak (Quercus suber L.) forests play an important ecological and economic role. Ectomycorrhizal fungi (ECMF) are key components for the sustainability and functioning of these ecosystems. The community structure and composition of ECMF associated with Q. suber in different landscapes of distinct Mediterranean bioclimate regions have not previously been compared. In this work, soil samples from cork oak forests residing in different bioclimates (arid, semi-arid, sub-humid, and humid) were collected and surveyed for ectomycorrhizal (ECM) root tips. A global analysis performed on 3565 ECM root tips revealed that the ECMF community is highly enriched in Russula, Tomentella, and Cenoccocum, which correspond to the ECMF genera that mainly contribute to community differences. The ECMF communities from the rainiest and the driest cork oak forests were distinct, with soils from the rainiest climates being more heterogeneous than those from the driest climates. The analyses of several abiotic factors on the ECMF communities revealed that bioclimate, precipitation, soil texture, and forest management strongly influenced ECMF structure. Shifts in ECMF with different hyphal exploration types were also detected among forests, with precipitation, forest system, and soil texture being the main drivers controlling their composition. Understanding the effects of environmental factors on the structuring of ECM communities could be the first step for promoting the sustainability of this threatened ecosystem.

As estatísticas dos incêndios florestais revelam que ao longo dos últimos 36 anos, Portugal foi o único entre os países do sul da Europa que não conseguiu reduzir significativamente a média anual da área ardida. Os trágicos incêndios de 2017, mais uma vez, revelaram a extrema vulnerabilidade de Portugal a condições meteorológicas extremas e a premência em encontrar meios eficazes de gestão dos combustíveis. Apesar da Estratégia Nacional para as Florestas (ENF), prever a gestão de combustíveis através do pastoreio, a sua promoção não tem sido efetiva, sendo muitas vezes, mesmo em meios técnicos, vista com desconfiança. A promoção do pastoreio dirigido (consumo de combustíveis) é complexa, a possibilidade de transformar combustíveis em recursos alimentares reclama a integração de conhecimentos multidisciplinares.

Aim of study: This paper aims to characterize some soil properties within the first 25 cm of the soil profile and the herbaceous biomass in Quercus forests, and the possible relationships between soil properties and understory standing biomass. Area of study: Three monoespecific Quercus forests (Q. suber L., Q. ilex subsp. rotundifolia Lam. and Q. pyrenaica Willd) in NE Portugal. Material and methods: During 1999 and 2000 soil properties (pH-KCl, total soil nitrogen (N), soil organic carbon (SOC), C/N ratio, available phosphorus (P), and available potassium (K)) and herbaceous biomass production of three forest types: Quercus suber L., Quercus ilex subsp. rotundifolia Lam. and Quercus pyrenaica Willd were studied. Main results: The results showed a different pattern of soil fertility (N, SOC, P, K) in Quercus forests in NE of Portugal. The C/N ratio and the herbaceous biomass confirmed this pattern. Research highlights: There is a pattern of Quercus sp. distribution that correlates with different soil characteristics by soil characteristics in NE Portugal. Q. pyrenaica ecosystems were found in more favoured areas (mesic conditions); Q. rotundifolia developed in nutrient-poor soils (oligotrophic conditions); and Q. suber were found in intermediate zones.

O sistema de pastoreio de percurso é um sistema de alimentação itinerante em que o rebanho percorre uma complexa rede de circuitos com periodicidade variável. Os circuitos de pastoreio cruzam unidades territoriais (parcelas, pousios bosques, etc.) muito diversas, com recursos forrageiros de elevada heterogeneidade em valor, abundância e sazonalidade. Este tipo de pastorícia representa a forma de produção e exploração das variadas raças de pequenos ruminantes no Nordeste de Portugal. Os percursos de pastoreio correspondem à optimização da satisfação de diversas necessidades dos rebanhos (alimentação, repouso, abeberamento, etc.), de variáveis estruturais (localização dos estábulos, dos pontos de água, acessos, etc.) e de restrições de uso (interdição do território por posturas municipais, regras ancestrais comunitárias, novas plantações, etc.). A interdependência e interligação funcional das diferentes unidades territoriais ao longo dos circuitos de pastoreio implica que pequenas alterações na ocupação ou utilização do território alterem o modelo de percurso a optimizar. Este trabalho pretende evidenciar essa interdependência espacial e funcional entre as diversas unidades territoriais neste complexo sistema de utilização de recursos. Durante um ano, os circuitos de pastoreio de dois rebanhos de ovinos e dois de caprinos foram monitorizados, mediante GPS ("Sistema de Posicionamento Global"). Para cada circuito de pastoreio monitorizado, paralelamente à sua localização espaço-temporal, registou-se a unidade territorial atravessada (ocupação do solo), a sua composição e a sua estrutura.

Cork oak (Quercus suber L.) and holm oak (Quercus rotundifolia) ecosystems are characteristic of Mediterranean forestry in Portugal. Even though cork is the most valuable product, these ecosystems provide multiple products and services. Assessing trade-offs between multiple goals is thus critical for the effectiveness of oak ecosystem management planning. This paper focuses on the development of a decision support system for oak ecosystems' scenario analysis including multiple criteria. It includes an innovative decision support systems (DSS) functionality to assess trade-offs between the criteria that may support negotiation and consensus building between decision-makers and forest stakeholders. Specifically, a module that encapsulates the Feasible Goals Method/Interactive Decision Maps (FGM/IDM) technique is developed for interactive visualization of the Pareto frontier. The Pareto frontier illustrates the degree to which improving one particular criterion requires accepting sacrifices in the achievements of others. It thus provides information about trade-offs between competing decision-makers' preferences. Results are discussed for a large-scale application encompassing over 1 million ha of cork and holm oak forest ecosystems in Southern Portugal. This study demonstrates the potential of the new

Whenwecomparedbreedingbirdcommunitiesin cork oak patches located before

This counterintuitive response may be due to the characteristics of cork oak (Quercus suber), a sclerophilous tree that is very resilient to fires and able to recover foliage in the following spring season, thus allowing rapid bird recolonization.

Renowned historians have been studying the causes and consequences of the Francoism economic autarchy during the 40s in the 20th century. This goal of this model was the agricultural and industrial self-sufficiency, using political methods and underestimating classical ones of economic management, by adopting the model of fascist Italy and national socialist Germany. The consequence of it all was a great economic disaster which affected the country agricultural and industrial fabric. Through the study of the correspondence between two managers, it is shown in this
assignment the concerns of the daily management and supplies of a first level and highly mechanised agricultural company, victim of the autarchy (shortage of industrial goods, raw materials, etc...): El Castell del Remei.

First ever report on cork-geopolymer composites for EMI shielding applications. Maximum total shielding effectiveness values ranging from À13.8 to À15.9 dB. This highly sustainable material may ensure large-scale electromagnetic protection.

Cork is a renewable and sustainable material, highly porous and lightweight. We valorised waste cork and recycled wine stoppers to make pyrolysed/carbonised solid cork, for use as economic and sustainable microwave (MW) absorbers at the microwave X-band (8-12 GHz), without binder or additives. Although cork is already a very lightweight material (0.16 g cm -3 ), the pyrolysed cork is five-times less dense at 0.031 g cm -3 , was amorphous graphitic carbon, and had an excellent shielding effectiveness (SE T ) of -18 to -38 dB, depending on thickness, with attenuation of the electromagnetic energy through internal reflection within the cellular cork structure. Furthermore, this ultra-light-weight material has an extremely high MW specific shielding effectiveness or efficiency (SSE), between -640 to -1235 dB g -1 cm 3 over the entire X-band range, depending on thickness (3.0-8.6 mm), one of the highest reported for any pure carbon material, this upper value being more than twice that of any previously reported graphite-based foams.

Variation of morphological and structural traits in natural cork oak populations along temperature and precipitation gradient

2024

Forest species have adapted to their local climate by changing some of their phenological characteristics. Differential phenological responses may modify tree chance of survival by altering the competitive balance between them. The study of key phenological stages (budding, budburst, flowering, falling leaves...) knew a renewed interest these last years for climate changes consequences researches. Characterizing the phenological variability response, of five Tunisian cork oak populations from contrasting climatic situations, in front to water deficit, has been the subject of this study. Large differences between populations from highest and coldest sites as well as those of lowest and warm sites were detected and adaptative responses specific to some populations were founded.
