“…This pattern of lower bird species richness in monocultures was also observed by Volpato et al (2010) and Mendonça-Lima (2012) in pine plantations, and Motta-Junior (1990), Marsden et al (2001) and Barlow et al (2007) in eucalyptus plantations. This occurs because silviculture areas increase habitat similarity (Marsden et al, 2001;Filloy et al, 2010), supply fewer resources such as appropriate substrates for nesting and foraging, and thus similar bird communities are expected (Motta-Junior, 1990;Kwok and Corlett, 2000). Furthermore, the understory is less developed than in native forests, resulting in loss of habitat for many species (Fischer et al, 2006;Barlow et al, 2007).…”

“…Vegetation structure (e.g. richness, stratification) is an important factor affecting the composition of bird communities (Hobbs et al, 2003;Gabriel, 2009;Filloy et al, 2010;Volpato et al, 2010;Mendonça-Lima, 2012). In silviculture areas, avian communities may consist mainly of habitat generalists, i.e., species that use a relatively wide set of habitat resources (Colles et al, 2009), and species associated with forest edges and open areas.…”

Structure of bird communities in eucalyptus plantations: nestedness as a pattern of species distribution

Replacement of native habitats by tree plantations has increased dramatically in Brazil, resulting in loss of structural components for birds, such as appropriate substrates for foraging and nesting. Tree plantations can also reduce faunal richness and change the composition of bird species. This study evaluated the structure of avian communities in eucalyptus plantations of different ages and in a native forest. We classified species as habitat specialists or generalists, and assessed if the species found in eucalyptus plantations are a subset of the species that occur in the native forest. Forty-one sampling sites were evaluated, with three point counts each, in a native forest and in eucalyptus plantations of four different ages. A total of 71 bird species were identified. Species richness and abundance were higher in the native forest, reflecting the greater heterogeneity of the habitat. The composition of bird species also differed between the native forest and plantations. The species recorded in the plantations represented a subset of the species of the native forest, with a predominance of generalist species. These species are more tolerant of habitat changes and are able to use the plantations. The commercial plantations studied here can serve as a main or occasional habitat for these generalists, especially for those that are semi-dependent on edge and forest. The bird species most affected by silviculture are those that are typical of open grasslands, and those that are highly dependent on well-preserved forests.Keywords: avian fauna, subsets, eucalyptus plantations, native forest. Estrutura de comunidades de aves em plantios de eucalipto:aninhamento como padrão de distribuição de espécies Resumo A substituição de ambientes nativos pela silvicultura está se tornando uma prática cada vez mais comum no Brasil, resultando na perda de componentes estruturais para as espécies de aves, como substratos específicos de forrageamento e nidificação. Esta prática pode reduzir a riqueza e alterar a composição das comunidades de aves. O objetivo deste estudo foi avaliar diferenças na estrutura de comunidades de aves em plantios de eucalipto de diferentes idades e em floresta nativa. Além disso, teve como objetivo classificar espécies em especialistas ou generalistas de habitat e avaliar se espécies encontradas nos plantios de eucalipto representam subconjuntos da floresta nativa. Quarenta e um sítios de amostragem foram avaliados, com três pontos de contagem cada, em uma floresta nativa e em plantios de eucalipto de quatro diferentes idades. Foi identificado um total de 71 espécies de aves. A riqueza de espécies e abundância foram maiores na floresta nativa refletindo a maior heterogeneidade desse habitat. A composição de espécies de aves também diferiu entre a floresta nativa e os plantios. As espécies registradas nos plantios representam um subconjunto das espécies da floresta nativa, o que é explicado pelo predomínio das espécies generalistas. Essas espécies são mais tolerantes às alterações de habitat e...

Intensive agriculture erodes β‐diversity at large scales

et al. 2012

Biodiversity is declining from unprecedented land conversions that replace diverse, low-intensity agriculture with vast expanses under homogeneous, intensive production. Despite documented losses of species richness, consequences for β-diversity, changes in community composition between sites, are largely unknown, especially in the tropics. Using a 10-year data set on Costa Rican birds, we find that low-intensity agriculture sustained β-diversity across large scales on a par with forest. In high-intensity agriculture, low local (α) diversity inflated β-diversity as a statistical artefact. Therefore, at small spatial scales, intensive agriculture appeared to retain β-diversity. Unlike in forest or low-intensity systems, however, high-intensity agriculture also homogenised vegetation structure over large distances, thereby decoupling the fundamental ecological pattern of bird communities changing with geographical distance. This ~40% decline in species turnover indicates a significant decline in β-diversity at large spatial scales. These findings point the way towards multi-functional agricultural systems that maintain agricultural productivity while simultaneously conserving biodiversity.

“…In general, anthropogenic habitats preserving—even partially—the original environmental conditions and the structure and composition of native vegetation are more suitable for native species than habitats producing a drastic change (Filloy et al . ). Two general criteria of classification have been used to analyse the response of bird assemblages to human disturbance: feeding guilds and the degree of habitat specialization (a proxy for ecological niche amplitude).…”

Bird Assemblages in Anthropogenic Habitats: Identifying a Suitability Gradient for Native Species in the Atlantic Forest

Traditional approaches to the study of species persistence in fragmented landscapes generally consider a binary classification of habitat being suitable or unsuitable; however, the range of human‐modified habitats within a region may offer a gradient of habitat suitability (or conservation value) for species. We identified such a gradient by comparing bird assemblages among contrasting land uses (pine plantations of different age, annual crops, clear cuts and cattle pastures) in the Upper Parana Atlantic forest. Bird assemblages and vegetation structure were characterized in an extensive area of 4400 km2 in Argentina and Paraguay during the breeding seasons of 2005–2010. Similarity of bird assemblages between anthropogenic habitats and the native forest and the proportion of forest species increased with vegetation vertical structure, while the proportion of open‐area species decreased. As a consequence, mature tree plantations were the most suitable habitats for forest species and were mainly used by frugivores and bark insectivores. In contrast, open habitats were the least suitable habitat for forest species and were used primarily by insectivores. Human‐created habitats that are structurally complex can be used by a subset of forest species, and may improve functional connectivity and mitigate edge effects. The conservation of large tracks of native forests, however, is critical for the long‐term persistence of the entire bird assemblage, especially for native forest dependent species.
