In the mixed colony, Great Crested Grebes bred later than in their monospecific colonies, while laying clutches of similar size, but significantly fewer of their nests disappeared during incubation and their chicks had higher survival rates up to at least 20 days old. Human disturbance and the resulting increases in predation likely caused greater losses at monospecific colonies of Great Crested Grebes where there is no common anti-predatory activity; while the strong anti-predatory behaviour of Whiskered Terns in the mixed colony might have offered enhanced protection to the chicks. Unfortunately, we could not separate the effects of the seasonal differences in human disturbance and of the protective presence of terns on the Great Crested Grebe's reproductive output.

We treated the experimental specimens with colcemid in order to visualize C-metaphases, and with labelled thymidine in order to evidence DNA synthesis in these bacteria-carrying cells. In both young and old nymphs, the C-metaphases showed a similar trend: their average number was only 0.3 per 100 bacteriocytes counted throughout the entire instars. In the young nymphs, the number of bacteriocytes in the S phase was congruent with the frequencies of the C metaphases. Since the number of M or S bacteriocytes was not sufficient to account for the observed increase in number of these endosymbiotic cells during nymphal development, we hypothesize a mechanism of bacterial transmission from bacteriocytes to other fat body cells that may explain the numerical growth of the bacter...

Nous avons capturé 97 individus de 13 espèces appartenant à 6 familles : Mégadermatidés (Cardioderma cor), Rhinolophidés (Rhinolophus clivosus), Nyctéridés (Nycteris hispida et N. thebaica), Vespertilionidés (Myotis tricolor, Nycticeinops schlieffeni, Pipistrellus kuhlii et Neoromicia nanus), Molossidés (Chaerephon pumila, Mops condylurus et M. demonstrator), Emballonuridés (Taphozous perforatus et Coleura afra). Lavia frons (Mégadermatidés) a été observé mais non capturé. La présence de bâtiments autour des stations de piégeage a affecté de manière significative le succès du piégeage. L'abondance, la richesse et la diversité se sont avérées variables selon les sites, en relation avec des différences dans la structure écologique des habitats forestiers, semi-désertiques ou insulaires...

Yet, empirical evidence suggests that it does not always so. In this study we test this hypothesis using a completely sampled mainland-island system, the arid clade of Hemidactylus, a group of geckos mainly distributed across Africa, Arabia and the Socotra Archipelago. To such purpose, we generated a new molecular phylogeny of the group on which we mapped body size and head proportions. We then explored whether island and continental taxa shared the same morphospace and differed in their disparities and tempos of evolution. Insular species produced the most extreme sizes of the radiation, involving accelerated rates of evolution and higher disparities compared with most (but not all) of the continental groups. In contrast, head proportions exhibited constant evolutionary rates across the radiation and similar disparities in islands compared with the continent. These results, although genera...

La production en Chine s'est averee tres forte, plus importante qu'au Pakistan, probablement en relation avec une grande disponibilite de zones humides pour l'alimentation. La forme sombre de l'Aigrette garzette de la cote du Pakistan presentait une productivite significativement plus faible que celle des formes blanches.

Using Socotran reptiles as models, we aim to relate richness of widespread and restricted-range species directly with landscape variables and to compare the impact of setting conservation targets for lineages versus species. Socotra Island is a UNESCO Natural World Heritage Site, containing high levels of endemism in relation to its area, especially of reptiles, the vertebrates with the most comprehensive available genetic data. We predicted the occurrences of reptile species using distribution models and used a novel approach to interpolate maps of spatial phylogenetic patterns. Patterns of intra and interspecifc diversity and differences between spatial outputs of lineage and species richness were related to eco-geographic variables. We evaluated differences in target achievement for each conservation unit within prot...
