The continued preservation of bison is one of Parks Canada’s greatest success stories. Canadian parks have been actively involved in protecting bison for over 100 years. While much has been written about the history of bison and Indigenous peoples, the destruction of the great bison herds in the nineteenth century, and individual conservation herds, there are few works that speak of the history of the Parks Canada bison herds as a whole. Like Distant Thunder combines these disparate threads to form a cohesive narrative of the bison herds managed by Canada.

Not-guilty verdicts, mistrials, and impunity for the Bundy family and many of their supporters in the armed confrontations over public land use in Nevada and Oregon. Expanded access for private oil, gas, mining, and logging industries and the downsizing of national monuments such as Bears Ears lead by Secretary of the Interior Ryan Zinke. A number of highly contentious debates and sensationalized events have again focused attention on land held in the public domain by the United States. This essay argues that federal land policy as a form of colonial administration has been constitutive for the logic of expectation as property in what is now the United States. From the state land cessions negotiated on behalf of the Articles of Confederation to the preemption acts (1830–1841) to the homestead acts (1862–1916) to present-day demands for land transfer, the acquisition and disposal of the so-called public domain have been central to westward colonization, the consolidation of the nation-state, and the promise of land ownership as the ostensible foundation of individual liberty. These dynamics are evident in contemporary conflicts over public lands and arguments for the transfer of public lands to either state or private ownership. Approaching the Bundy occupations as flashpoints that illuminate competing interpretations and claims to land within the history of westward colonization, this essay seeks to demonstrate the ways in which expectation emerges from particular economies of dispossession of indigenous peoples that have historically worked through and across the division of public and private property.

FOR LIJIANG OLD TOWN 丽江古城, 1 June 2016 was not a happy day. More than 800 hostels, guesthouses, and shops refused to open their doors. They had made a collective decision to protest against the local government’s insistence that they collect an eighty-yuan ‘conservation fee’ 维护费 from foreign and domestic tourists. The shop owners, mainly migrants from other parts of China, complained that the seemingly arbitrary nature of the request was hurting business. The three-day protest resulted in a dramatic decrease in tourist numbers —transforming this popular vacation spot into a ghost town.Places like Lijiang easily become stereotyped ‘theme parks’ in which local communities play a marginal role, entangled in the battle between local bureaucracies and business. It is in this struggle that old towns lose the very core of their cultural value.

This paper discusses through a series of tests and three case studies (a 1930s embroidery, an Inuit blouse ribbon and a seventeenth‐century Doge's hat) recent developments in the application of solvent reactivated hydroxypropyl cellulose (Klucel G®).At the Textile Conservation Centre different application techniques in reactivating adhesive‐coated silk crepeline with Industrial Methylated Spirit (IMS) and acetone (2‐propanone) were tested in order to assess their suitability in the conservation of severely deteriorated textile materials. The ease and control of application, the final appearance and the bonding strength were evaluated using subjective tests.These tests showed that Klucel G® (as a 4% w/v dispersion cast as a film on silk crepeline or habutai) could successfully be reactivated to form sufficiently strong bonds using IMS, either in the solvent's liquid or vapour phase.

Amidst the expected, punning advertisements for data companies lining the drive into San Francisco, one passes a lone cultural billboard depicting Klimt’s The Virgin (1913). The image advertises Klimt & Rodin: An Artistic Encounter at the Legion of Honor. Below the image of entwined pale, female flesh against a tapestry of vibrant color are the words: “Gives off seriously sexual vibes,” excerpted from a review in San Francisco Magazine. Klimt & Rodin showcases the two male artists’ interest in depicting the white female subject, an art historical mainstay since the splash of Praxiteles’s naked Aphrodite of Knidos. Vibrant colors and gilt dominates the non-figural spaces of Klimt’s canvases, but not the subjects’ bodies, which are rendered in light flesh tones, highlighted with pale yellows and pinks. Rodin’s sculptures, in contrast, are hewn from monochrome materials—marble, bronze, clay—with no surface treatments. If the “seriously sexual vibes” advertised on the billboard come from the expected space of white female (and feminized) subjectivity, the “artistic encounter” on display is one of medium—of painting’s uncontested polychrome in contrast to the insistent monochrome of modern sculpture.

Este artículo es una extensa revisión sobre el pasado, presente y futuro del panorama que envuelve las estimaciones poblacionales de lobos en España. Lo que subyace detrás de estas estimas loberas es enrevesado y difícil de interpretar racionalmente. Lo peor de todo es que la gestión del lobo recae en administraciones sometidas al yugo del ruido mediático de ciertos sectores, y que acaban ignorando el importante papel ecológico de esta especie. Por tanto, la conservación efectiva y la restitución de la biodiversidad quedan en un plano totalmente testimonial.

This presents a management strategy for the urban waterlogged deposits and archaeological remains at Nantwich, Cheshire, endorsed as a Supplmentary Planning Document by East Cheshire Council for its local plan. It advocates a holistic solution for preventing dessication of the deposits by raising awareness with all urban planners (spatial planners, water engineers, highways engineers, utility providers, as well as developers and other parties) to change their approach to have more permeable surfaces (inclusing SUDS) and allow rainwater to percolate through the deposits, helping preservation of organic archaeological remains and preventing subsidence of the timber-frame historic buildings that form the historic centre and conservation area of the town.

- Diligenza e prestezza.è uno studio sulla tecnica della pittura attraverso l’analisi incrociata dei testi letterari e delle opere d’arte. Dopo aver ripercorsa la fortuna critica dei testi dei principali autori – Leonardo, Vasari, Armenini, Borghini, Lomazzo – ne vengono messe a confronto le informazioni sul disegno e sulla pittura, analizzandone il lessico specifico e individuando i materiali e i procedimenti esecutivi. Al tempo stesso alcuni temi centrali del dibattito teorico – il disegno l’invenzione, il paragone tra le arti – sono esaminati alla luce del loro rapporto con la tecnica. Infine alcuni dipinti del museo di Capodimonte, scelti come casi esemplificativi, sono stati analizzati sulla base degli studi scientifici e delle fonti.

Alvar Aalto’s career – his perspectives as seen in his writings and in his architecture - progressed from being initially influenced by classicism (which he applied in a playful manner aligned with Nordic Romanticism), on to modernist functionalism and rationalist attitudes (through his contact with the International Congresses of Modern Architecture (CIAM) and its prominent members), which he later developed further into his own ‘humane architecture’ encompassing the psychophysical field.

Payments for ecosystem services (PES) programs are one prominent strategy to address economic externalities of resource extraction and commodity production, improving both social and ecological outcomes. But do PES and related incentive programs achieve that lofty goal? Along with considerable enthusiasm, PES has faced a wide range of substantial critiques. In this paper, we characterize seven major classes of concerns associated with common PES designs, and use these as inspiration to consider potential avenues for improvements in PES outcomes and uptake. The problems include (1) new externalities, (2) misplacement of rights and responsibilities, (3) crowding out existing motivations, (4) efficiency-equity tradeoffs, (5) monitoring costs, (6) limited applicability, and (7) top-down prescription/alienating agency. As currently practiced, many PES programs are thus of limited benefit and even potentially detrimental to sustainability. From this dire conclusion, we highlight several innovations that might be combined and extended in a novel approach to PES that may address all seven problems. Recognizing that PES necessarily articulate and even normalize values, our proposed approach entails designing these institutions intentionally to articulate rights and responsibilities conducive to sustainability—those we might collectively seek to entrench. Problems remain, and new ones may arise, but the proposed approach may offer a way to reimagine PES as a major social and economic tool for enabling sustainable relationships with nature, conserving and restoring ecosystems and their benefits for people now and in the future.

White-nose syndrome (WNS) and wind-turbine facilities on the Delmarva Peninsula are emerging threats to the peninsula's current bat fauna. However, until our study, there had been no assessment of bat populations or their habitats in that region. The purpose of our research was to fill this gap by using 28 road-based transects and 24 passive-monitoring sites to acoustically monitor bats across the peninsula. In total, we recorded 4432 bat-call sequences and documented the presence of at least 6 species: Lasiurus borealis (Eastern Red Bat), Eptesicus fuscus (Big Brown Bat), Nycticeius hu-meralis (Evening Bat), L. cinereus (Hoary Bat), Perimyotis subflavus (Tri-colored Bat), 1 or more species in the genus Myotis, and potentially Lasionycteris noctivagans (Silver-haired Bat). Given the similarity in call structure between Silver-haired and Big Brown Bats, we cannot say with certainty the former were present. Eastern Red Bats, Evening Bats, and Hoary Bats were relatively widespread and abundant; Tri-colored Bat and Myotis were not. Of the species for which adequate sample sizes were available, all but the Hoary Bat (and possibly the Silver-haired Bat) showed strong preferences for forest edges, demonstrating the importance of these landscape features for maintaining healthy bat populations. Point-counts along road transects and stationary-monitoring sites yielded similar results, suggesting that road-based transects are a valuable tool for surveying bat populations across large geographic areas.

Actions directed at saving the remaining natural resources, be it forests, biodiversity, or
whole ecosystems should be expected to increase as levels of environmental degradation increase. This expectation is consistent with the comment of Dudley et al(1999) that there is an excellent outlook for protected area increases; and with information indicating that since 1962 protection of public areas has increased tenfold(Molnar 2005). For example, most countries have already protected or are planning to protect a percentage of their resource base, and pressures from NGOs seeking maximum protection are right now strong. Conservation International reports that in 2005 it has projects in 40 countries(Seligmann 2005). Also, the conflict between social goals and preservation goals should be expected to increase as the levels of natural resources available for traditional social uses decrease. For example, as environmental stakeholders press for more resource protection, social stakeholders will press for their right to exploit their available resources, especially, sustainably. This should not be a surprise as the conflict between conservation and the people or communities affected by it is known(Wright1996; Stolton and Dudley 1999) and it is now more widely recognized(Molnar 2005).

ABSTRACT A simple sol-gel technique for the preparation of methyl–modified silica coatings for the protection of the external surface of copper has been used in this study. Tetraethylorthosilicate (TEOS) has been used as a precursor to prepare nanosilica coatings on the surface of copper. The methyl–modified silica sols were obtained by mixing of 3% SiO2 sol solution with trimethylchlorosilane (TMCS) or hexamethyldisilozane (HMDS) as basic materials. For comparison, the copper substrates were also coated with commercial polymers (Paraloid B 72, Plexisol P 550-40 and polyvinyl butyral (PVB)). The surface morphology changes of uncoated and coated specimens were investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The hydrophobicity of surfaces and photochemical ageing effects were evaluated by contact angle measurements. Potentiodynamic measurements were obtained in order to compare corrosion parameters of the coatings.

Land-use/land-cover change is the most important factor in causing biodiversity loss. The Mediterranean region has been affected by antropic disturbance for thousands of years, and is, nowadays, one of the most significantly altered hotspots in the world. However, in the last years a significant increase in forest cover has been measured. These new patterns are independent from planned conservation strategies and appear to have a substantial impact on landscapes and biodiversity. We used three land-use/land-cover maps (from 1960 to 2000) covering the Italian peninsula to analyze the pattern of land-use/land-cover change. We measured an increase in forests, especially in mountains, an increase in artificial areas, especially in coastal zones, and a decrease in pastures. Intensively cultivated areas showed a limited decrease while extensively cultivated ones showed a marked decrease. In the same period mammal and bird species followed a similar pattern, with forest birds, ungulates and carnivores increasing, and typically Mediterranean species decreasing. We suggest that our results may provide important information, which could be useful for conservation planning in the entire Mediterranean hotspot. We suggest that an increasing conservation effort should be made to protect the Mediterranean-type forests and scrublands, as well as traditional agricultural practices. Moreover, future conservation efforts should consider the broad socio-political and ecological processes that are most likely to occur across the whole hotspot, especially along coastal areas, and the network of protected areas should be functionally integrated in a conservation strategy that includes the human-dominated landscape.

The status of the Mediterranean Monk Seal, Monachus monachus, has been studied over a five-year period between 1994 and 1998 in the Foça Pilot Monk Seal Conservation Area. The identification of individual seals occurring in the area, their spatial distribution and biology were studied using the results of direct cave surveys, land-based seal observations, and interviews. The population of Monk Seals was estimated to consist of 9 individuals, 6 of which were adult females and 3 were juveniles (one female, one male and one of unknown sex.). Islands off Foça town provide suitable habitats and promote the survival of the species. Of the 11 caves identified, two were found to be used for reproduction.Der Status der Mittelmeermönchsrobbe, Monachus monachus, wurde zwischen 1994 und 1998 in einer fünfjährigen Untersuchungsperiode im Mönchsrobbenschutzgebiet von Foça untersucht. Für die individuelle Erkennung von Robben im Untersuchungsgebiet, die Untersuchung ihrer räumlichen Verteilung und ihrer Biologie wurden direkte Beobachtungen an Meeresgrotten, Beobachtungen vom Land aus sowie Befragungen durchgeführt. Die Populationsgröße wurde zu 9 Individuen ermittelt, und zwar 6 adulte Weibchen und 3 Jungtiere (ein Weibchen, ein Männchen und ein Tier mit unbekanntem Geschlecht). Auf den vor der Stadt Foça gelegenen Inselchen gibt es passende Habitate, die das Überleben der Art ermöglichen. Von den insgesamt 11 erfassten Meeresgrotten wurden zwei für die Fortpflanzung genutzt.

Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos and aquariums promote attitude change, education, or interest in conservation in visitors, although further investigation of this possibility using methodologically sophisticated designs is warranted.

As the wilderness metaphor has decreased in utility due to widespread human-driven environmental change, conservationists and restorationists have struggled to find new ways to inspire nature conservation. Some have suggested gardening as a new metaphor, but many are wary of its implications, particularly for animals viewed as threats or pests. Others, however, point out positive attributes for the metaphor including its focus on stewardship of nature which allows for positive human agency in ecosystems. We argue a gardening metaphor may also allow increased flexibility in approaches to biodiversity conservation, in part by allowing goals to be fit to communities and their specific cultural contexts. Wild gardening would seek to preserve global biodiversity while acknowledging the pivotal role humans now play in that process. Here we review the use of the garden metaphor over the last 25 years and discuss what wild gardening might mean for restoration. Consistent with a long history of environmental thought, we suggest such a metaphor will work best if it is coupled with a civic/stewardship ethic and a good dose of humility on the part of all gardeners.
