Warming from climate change is expected to reduce body size of endotherms, but studies temperate systems have produced equivocal results. Over four decades, we collected morphometric data on a nonmigratory understory bird community within Amazonian primary rainforest that experiencing increasingly extreme climate. All 77 species showed lower mean mass since the early 1980s—nearly half with 95% confidence. A third concomitantly increased wing length, driving decrease in mass:wing ratio for...
Insectivores of the tropical rainforest floor are consistently among most vulnerable birds to forest clearing and fragmentation. Several hypotheses attempt explain this pattern, including sensitivity extreme microclimates found near borders, particularly brighter warmer conditions. Importantly, "microclimate hypothesis" has additional implications for intact under global climate change that could be evaluated through direct assessment light temperature environment terrestrial insectivores....
Abstract As data and computing power have surged in recent decades, statistical modeling has become an important tool for understanding ecological patterns processes. Statistical ecology faces two major challenges. First, may not conform to traditional methods, second, professional ecologists often do receive extensive training. In response these challenges, the journal Ecology published many innovative papers that introduced novel methods provided accessible guides best practices. this...
Nos últimos anos, o diagnóstico de TDAH aumentou no contexto escolar, aumentando também a quantidade pesquisas sobre assunto. O presente estudo investigou número alunos com em 17 escolas Porto Alegre e percepção 136 professores 1ª à 8ª série, transtorno comportamento das crianças TDAH. Dois questionários foram utilizados: um preenchido pela direção da escola outro, pelos professores. A média dos estudadas foi 3%, dois casos extremos: uma 51% outra 0,2%. Em relação professores, houve...
Although the duration of biological rhythms varies from milliseconds to decades, daily cycles are especially widespread for individual organisms. These circadian synchronized by light–dark cycles, which govern predictable changes in other microclimate variables. Despite fixed, regular nature these abiotic at low latitudes, little is known about how different animals structure activity along gradients. We used 25 years capture–recapture data and ~ 000 unique captures characterize ‘activity'...
Abstract How species interact with human‐disturbed environments is a central focus of conservation biology. Within disturbed landscapes, regenerating forests have potential to provide habitat for forest species, especially as increasing amounts primary are lost. As secondary regenerates beside forest, it increases heterogeneity. However, relatively little known about the influence heterogeneity on space use. In this study, we analyzed topography and vertical vegetation structure small...
Orange-fronted Plushcrown Metopothrix aurantiaca is a unique, but easily overlooked, small furnariid found in the midstorey and canopy of riverine areas Amazon. The species' previously published distribution includes parts southernmost Colombia, eastern Ecuador, Peru, northern Bolivia western Brazil. In easternmost part its (Brazil), M. occurs states Acre, Amazonas Rondônia, east to 64°W. We present nine new records species Brazil, all them known together extending range by c.750 km. These...

Humans significantly influence geographic patterns of biological invasions, creating conditions for species to overcome biogeographic barriers and colonize new areas. In the eastern United States, forested landscapes containing hemlock (Tsuga canadensis) are under threat by invasive woolly adelgid (Adelges tsugae). Although several studies have shown negative effects invasion in local bird communities, its regional impacts not yet been quantified. Using broad-scale spatial (entire US range...
