Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): multidisciplinary research initiative involving than 30 partner organizations working assess both social and ecological dimensions of land-use sustainability eastern Brazilian Amazonia. The approach adopted by RAS offers three advantages for addressing problems: (i) collection synchronized co-located socioeconomic data...
South America holds 30% of the world's avifauna, with Atlantic Forest representing one richest regions Neotropics. Here we have compiled a data set on Brazilian bird occurrence (150,423) and abundance samples (N = 832 species; 33,119 individuals) using multiple methods, including qualitative surveys, mist nets, point counts, line transects). We used four main sources data: museum collections, on-line databases, literature sources, unpublished reports. The comprises 4,122 localities from 1815...
Avian malaria is a vector transmitted disease caused by Plasmodium and recent studies suggest that variation in its prevalence across avian hosts correlated with variety of ecological traits. Here we examine the relationship between diversity lineages southeastern Amazonia and: (1) host traits (nest location, nest type, flocking behaviour diet); (2) density hosts; (3) abundance mosquitoes; (4) season. We used molecular methods to detect blood samples from 675 individual birds 120 species....
Summary Understanding how selective logging affects biodiversity is crucial to planning cost-effective conservation strategies in tropical forests, yet there limited understanding of its impacts on fauna functional diversity the Americas. We assessed intensification and time since influence multiple metrics integrity Brazilian Amazon by collecting bird dung beetle data within 48 management units that had experienced varying exploitation intensities between 1.5–2.0 5.0–6.0 years before faunal...
While many published maps of avian species richness indicate northern Amazonia to be somewhat species-poor, recent surveys reveal that this area actually possesses one the most species-rich avifaunas in Neotropical lowlands. Our at least 520 bird occur Viruá National Park (VNP) and adjacent areas, which is located Brazilian state Roraima (northern Amazonia). Here, we present results our ornithological efforts since 2001, based on audio-visual mist-netting surveys, vouchered by tape digital...
Abstract Aim To offer a test of expert knowledge about rarity twenty Amazon forest bird species following an approach that equates with low site occupancy and formally accounts for imperfect detection. We define ten pairs closely related species, each pair one hypothetically common rare species. Our null hypothesis is members have similar occupancy, hypothesized differences due to detection errors alone. Location A 1000‐ha plot primary rainforest in the central Brazilian Amazon. Methods...
Abstract Blackwater floodplain forests of the Rio Negro are susceptible to understory fires. Bird composition was distinct between burned and unburned forest but not young (12–18 yr) old burns (>25 yr), indicating low resilience after fire. Forest regeneration is slow, with open grassy areas persisting >80 yr.
We compared two methods routinely used to conduct bird community surveys: point counts and transects. Our aim was look for differences between these regarding detection of richness abundances. Additionally, we analyzed if one the provided higher correlation data with vegetation structure as an important habitat descriptor. From September 2014 January 2015, surveyed birds in 264 258 transects spread across southern Brazilian grasslands. conducted method direct sequence other, same place...
Abstract Aim One of the oldest and most powerful ways for ecologists to explain distinct biological communities is invoke underlying environmental differences. But in hyper‐diverse systems, which often display high species richness low abundance, these sorts community comparisons are especially challenging. The classic view Amazonian birds posits that riverine barriers habitat specialization determine local regional composition. We test tacit, complementary assumption similar bird should...
Abstract We report the records of three nests Straight-billed Reedhaunter, Limnoctites rectirostris , in southernmost Brazil. For each nest, we collected information about biometry, spatial localization within patch (border or inland) and cardinal orientation incubation chamber. Information on number eggs reproductive success is also presented. All were found early September. The situated edge patches guided chamber opening between north east. results are discussed. presented herein extends...
The Guianan Red Cotinga (Phoenicircus carnifex) is a poorly known member of the family Cotingidae, and information concerning its biology, ecology, natural history are scarce. We provide first description nest young additional data on diet habitat preferences.
