The microbial consortium within an organism is crucial for its development and immune *** of the host microbiome by antibiotics or antinutritional factors may contribute to increased disease ***,we investigated whether exposure to different microbes could influence zebrafish larval microbiota composition and modulate their immune response towards a saponin *** zebrafish were exposed to the antibiotic oxytetracycline(OxyT)or control tank water and their intestinal content was harvested after 30h(24h exposure,6h wash-out).Subsequently,zebrafish embryos were exposed to either OxyT-treated content or non-treated content from 3 to 6 days post fertilization(dpf).At 6 dpf part of the group received a saponin challenge until 8 *** larvae exposed to OxyT-treated adult gut content(3–6 dpf)showed an altered microbiota composition compared to ***,larvae exposed to saponin-treated OxyT-content showed fewer macrophages(as visualized by fluorescent microscopy using mpx:GFP114;mpeg:mCherry transgenic fish)in the overall fish as well as around the gut area than saponin-treated control-exposed *** macrophages were associated with a decreased expression of interleukin 22(il22)in larvae exposed to saponin-treated OxyT-content compared to ***,this study shows that exposure to different microbial environments early in life might affect disease susceptibility of larval zebrafish.

Secondary forests and human-made forest gaps are conspicuous features of tropical ***,behavioral responses to these aspects of anthropogenically modified forests remain poorly ***,we analyze the effects of small human-made clearings and secondary forests on tropical bats by examining the guild-and species-level activity patterns of phyllostomids sampled in the Central Amazon,***,we contrast the temporal activity patterns and degree of temporal overlap of 6 frugivorous and 4 gleaning animalivorous species in old-growth forest and second-growth forest and of 4 frugivores in old-growth forest and forest *** activity patterns of frugivores and gleaning animalivores did not change between old-growth forest and second-growth,nor did the activity patterns of frugivores between old-growth forest and ***,at the species level,we detected significant differences for Artibeus obscurus(old-growth forest ***-growth)and ***(old-growth forest ***).The degree of temporal overlap was greater than random in all sampled ***,for frugivorous species,the degree of temporal overlap was similar between old-growth forest and second-growth;whereas for gleaning animalivores,it was lower in second-growth than in old-growth *** the contrary,forest clearings were characterized by increased temporal overlap between *** in activity patterns and temporal overlap may result from differential foraging opportunities and dissimilar predation ***,our analyses suggest that activity patterns of bats in second-growth and small forest clearings,2 of the most prominent habitats in humanized tropical landscapes,varies little from the activity patterns in old-growth forest.

1924年建造的巴塞罗那工人合作社现已荒废近30年：风、雨、鸽子从这里进进出出,随着时间的推移,这栋建筑也变得越来越破败不堪。阳光从屋顶的洞口穿透,将光束直射进老旧大堂的中央,让室内的光景更显颓败。然而对于设计师而言,这并不是一场破坏,反而预示了建筑新的可能性。
