“…Previous studies have found that even small mixed forest remnants harbor rich bird assemblages, composed of many species that seem to use edge and forest interior indifferently [ 103 , [ 104 ]. For instance, Araucaria plantations–the dominant tree characterizing mixed forests–house sensitive and endemic birds associated with this forest type [ 105 ], [ 106 ]. A reasonable explanation for this pattern is the preadaptation of mixed forest avifauna to such disturbance, so that species loss due to this source of anthropogenic impact is lessened by the birds’ ability to live in secondary and/or disturbed forest fragments, hence diminishing dissimilarity in natural, rural and even urban areas.…”

Human-Induced Landscape Changes Homogenize Atlantic Forest Bird Assemblages through Nested Species Loss

The increasing number of quantitative assessments of homogenization using citizen science data is particularly important in the Neotropics, given its high biodiversity and ecological peculiarity, and whose communities may react differently to landscape changes. We looked for evidence of taxonomic homogenization in terrestrial birds by investigating patterns of beta diversity along a gradient of human-altered landscapes (HAL), trying to identify species associated with this process. We analyzed bird data from 87 sites sampled in a citizen science program in the south Brazilian Atlantic Forest. Regional-scale taxonomic homogenization was assessed by comparing beta diversity among sites in different HALs (natural, rural or urban landscapes) accounting for variation derived from geographical distance and zoogeographical affinities by georeferencing sites and determining their position in a phytogeographical domain. Beta diversity was calculated by multivariate dispersion and by testing compositional changes due to turnover and nestedness among HALs and phytogeographical domains. Finally, we assessed which species were typical for each group using indicator species analysis. Bird homogenization was indicated by decreases in beta diversity following landscape changes. Beta diversity of rural sites was roughly half that of natural habitats, while urban sites held less than 10% of the natural areas’ beta diversity. Species composition analysis revealed that the turnover component was important in differentiating sites depending on HAL and phytogeography; the nestedness component was important among HALs, where directional species loss is maintained even considering effects of sampling effort. A similar result was obtained among phytogeographical domains, indicating nested-pattern dissimilarity among compositions of overlapping communities. As expected, a few native generalists and non-native urban specialists were characteristic of rural and urban sites. We generated strong evidence that taxonomic homogenization occurs in the south Brazilian Atlantic Forest as a result of a directional and nested species loss, with the resultant assemblages composed of few disturbance-tolerant birds.

“…The elevation of the area ranges from 870 to 930 m above sea level. The PUC forest is a remnant fragment of Atlantic forest of 66 755 m², characterized as a semideciduous seasonal secondary forest with many species of insects, anurans, reptiles, birds (approximately 134 species, see Vasconcelos et al, 2013) and mammals. Currently, this area is surrounded by a densely anthropized urban matrix, which hampers or prevents the dispersal of many species to other fragments.…”

Anthropogenic noise, which is part of an urban soundscape, can negatively affect the behaviour of wild animals. Here we investigated how biophony (animal sounds) was affected by noise in an urban Brazilian forest fragment. Our hypothesis was that noise and biophony would differ between the border and the centre of the forest fragment (i.e., lower biophony predicted in noisy areas). Two passive acoustic monitoring devices were used to record soundscapes one week per month, 24 hour per day, from May to July 2012. The Acoustic Complexity Index (ACI) was used to quantify biophony and the Power Spectral Density (PSD) to quantify urban noise. PSD and ACI were higher on the border than in the centre of the fragment. PSD was lower in July, while the ACI did not significantly vary between months. Noise levels were also higher on the border. Conversely, potential species richness was higher in the centre of the forest fragment. Higher biophony at noisy sites can be interpreted as behavioural responses of species for communicating in noisy areas. Alternatively, they could be the result of species segregation by degree of vocal plasticity or due to differences in composition of communities.

“…The number of studies of birds in urbanized environments has become increasingly common, mainly due to the expansion of these environments over tropical forests (e.g., VASCONCELOS et al, 2013 andVOGEL et al, 2016 to Atlantic Forest;AVILLA et al, 2021 andRICO-SILVA et al, 2021 to Amazon), showing that the bird community persists through behavioral and morphological flexibility to increase a population's ability to cope with anthropogenic hazards (AVILLA et al, 2021). Therefore, the objective of this report is to describe and analyze the bird community in green areas and others under the influence of the water system in an urban landscape in the southwest Brazilian Amazon.…”

The Amazon presents an arc of deforestation which has expanded into natural areas and bird community studies in these areas are incipient for urban landscapes after transformation. Therefore, the bird community in an urban landscape in the southwest Amazonian region within an area in the arc of deforestation was investigated. The observations were performed through linear transects, during the wet and dry seasons of 2013. Records were obtained using binoculars and cameras. A total of 191 species of birds were recorded. The species accumulation curve was not reaching the asymptote, showing that new species can be recorded with a sampling effort increase. The community has low richness as a result of pressure on Amazonian environments and a high degree of anthropization. However, there is relevant composition, because nectarivores, insectivorous, carnivores, omnivores, and granivores were found in all environments, as well as endemic and threatened species.
