“…altitude , we used the highest limit of occurrence of each species at the Serra dos Órgãos mountain range, south‐eastern Brazil. We used this region as a reference because abundance variation across altitude is relatively well known there (Stotz et al ., ; Mallet‐Rodrigues, Parrini & Pacheco, ; Mallet‐Rodrigues et al ., ; G. S. Cabanne, unpubl. data) and also because it is where most of our target taxa occur.…”

The effects of global glaciations on the distribution of organisms is an essential element of many diversification models. However, the empirical evidence supporting this idea is mixed, in particular with respect to explaining tropical forest evolution. In the present study, we evaluated the impacts of range shifts associated with Pleistocene global glacial cycles on the evolution of tropical forests. In particular, we tested the predictions: (1) that population genetic structure increases with fragmentation variation between the present and the Last Glacial Maximum (LGM) and also (2) with geographical range instability; and (3) that genetic diversity increases with range stability and (4) decreases with fragmentation variation between periods. To address our predictions, we studied population genetic structures and modelled present and past distributions of 15 Atlantic Forest (AF) endemic birds. Afterwards, we evaluated the relationship of population genetic parameters with metrics of species range shifts between the present and the LGM. We found that geographical ranges of AF birds changed in concert with Pleistocene glacial cycles but, unexpectedly, our findings suggest the novel idea that ranges during glacial maxima were slightly larger on average, as well as equally fragmented and displaced from the interglacial ranges. Our findings suggest that range shifts over the late Pleistocene impacted on the diversification of forest organisms, although they did not show that those range shifts had a strong effect. We found that a combination of fragmentation variation across time, small current range size, and range stability increased population genetic structure. However, neither fragmentation, nor range stability affected genetic diversity. Our study showed that evolutionary responses to range shifts across AF birds have a high variance, which could explain the mixed support given by single‐species studies to the action of Pleistocene range shifts on population evolution.

“…In general, the results of this study showed that vegetation gradients in mountains affect the local distribution and abundance of bird species, and consequently the composition and structure of bird communities (Navarro 1992, Blake and Loiselle 2000, Melo-Júnior et al 2001, Mallet-Rodrigues et al 2010). In the Serra da Bodoquena, a mountainous region also located in the western Brazil, the bird communities are organized in relation to local vegetation gradients, with communities of forests, savannas and grasslands (Godoi et al 2016).…”

Different vegetation types are distributed in mountains according to altitude, topography and soil. The composition and structure of bird communities in these areas can change in relation to the vegetation gradient, with particular communities occupying each habitat type. In this study we present the changes in composition, species richness and bird abundance over the gradient of forests, savannas and altitudinal grasslands of Maciço do Urucum, a mountainous region located in the Chiquitano Dry Forests domain in western Brazil. We recorded 165 bird species through qualitative and quantitative methods. Forested savannas, riparian forests and submontane forests presented the highest richness and abundance of birds, while arboreal savannas and altitudinal grasslands had intermediate and low values, respectively. The bird composition was similar between riparian and submontane forests, while other vegetation types present more dissimilar bird communities. Our results show differences in composition, richness and bird abundance among the vegetation types present at Maciço do Urucum, and highlight an important function of vegetation gradients for the conservation of bird communities in mountains. Additionally, this is the first study of the bird communities in the Brazilian Chiquitano Dry Forests, an important domain in the west of Brazil which has been poorly studied.

ABSTRACT. The state of Rio de Janeiro as the southern and northern boundary of the distribution of some bird species. The state of Rio de Janeiro is located in a region that can be considered biogeographically important for harboring extreme geographical limits of the Serra do Mar and lowland forests, which are very significant for the distribution of several bird species. In this study, through extensive bibliographic search, 59 bird species were found with their southern (40 species) or northern (19 species) limit of distribution located in the state of Rio de Janeiro. Birds with the southern limit of distribution in Rio de Janeiro have been recorded in almost the entire state, except in the upper valley of the Paraíba do Sul river and the western portion of the coastal zone of the state. This birds species are predominantly associated with lowland and submontane forests and more than half is included in the list of species threatened with extinction in the state. Birds with the northern limit of distribution in the state of Rio de Janeiro can be classified into two basic groups according to their distribution pattern in the region. The first group consists of endemic montane Atlantic forest birds, while the second group consists of occasional visitors associated with aquatic environments. The low proportion of threatened bird species among those with the northern limit of distribution in Rio de Janeiro can be explained by the high proportion of species inhabiting montane forests, which are more protected than the lowland forests.KEYWORDS. Atlantic Forest, Biogeography, geographical distribution, Serra do Mar, southeastern Brazil. RESUMO.A região onde se localiza o estado do Rio de Janeiro pode ser considerada biogeograficamente importante por abrigar os limites geográficos extremos da Serra do Mar e das florestas dos tabuleiros (ou de baixada), formações bastante significativas para a distribuição de diversas espécies de aves. Nesse estudo, através de extensa consulta bibliográfica, foram encontradas 59 espécies de aves com seu limite sul (40 espécies) ou norte (19 espécies) de distribuição geográfica localizado no estado do Rio de Janeiro. As espécies com limite sul de distribuição no estado têm registros em quase todo o território fluminense, exceto na região do alto vale do rio Paraíba do Sul e na porção mais ocidental da costa fluminense. São espécies predominantemente associadas às florestas de baixada e submontanas e mais da metade está incluída na lista de espécies ameaçadas de extinção do estado. As espécies com limite norte de distribuição no Rio de Janeiro podem ser classificadas em dois grupos básicos quanto ao seu padrão de distribuição em território fluminense. O primeiro grupo é composto por espécies de ambientes florestais montanos e endêmicas da Mata Atlântica, enquanto o segundo grupo é constituído por visitantes ocasionais associados a ambientes aquáticos. A baixa representatividade de espécies ameaçadas entre aquelas com limite norte de distribuição no Rio de Janeiro pode ser explicada pela...
