“…Generalist species are often favoured in habitat edges, because they offer access to new habitats and resources (e.g. pollinators: Burgess et al, 2006, herbivores: Wirth et al, 2008, predators and nest predation: Chalfoun et al, 2002Lidicker, 1999), whereas specialists typically decline (plants: Laurance et al, 1997Laurance et al, , 2006aTabarelli et al, 2008, insectivorous birds: Restrepo and Gómez, 1998, vertebrates: Hansson, 1994, but see Pardini et al, 2009 for a multi-taxa approach).…”

“…forest regrowth) can minimise edge effects by supporting a proportion of the communities in the fragments (Laube et al, 2008;Pardini et al, 2009 and references therein). A diverse and structurally complex, anthropogenic matrix may even harbour a significant fraction of the original biota, potentially reducing biodiversity loss (Lindenmayer and Luck, 2005;Pardini et al, 2009). For instance, in Western Kenyan rainforest, some bird species (11% out of 194 forestdependent species; Bennun and Njoroge, 1999) also used the heterogeneous farmland close to the forest as feeding habitat, gaining access to additional food resources outside their core habitat (Laube et al, 2008).…”

“…The contrast between predefined habitat requirements for species (especially in the LOW FD category) and our results highlighting the need of forest for community persistence, is problematic considering that a significant proportion of applied research focuses only on species classified as habitat specialists (i.e., vulnerable) in birds (e.g., Julliard et al 2006), mammals (e.g., Puettker et al 2008) and insects (e.g., Rand and Tscharntke 2007). Traditionally, classification schemes are often derived solely from observational approaches that do not account for detection biases (Azeria et al 2007, Pardini et al 2009). Research based on such classification schemes may misrepresent true patterns of habitat use for a large number of species in a community, and misidentify or underestimate which species will be most impacted by environmental changes.…”

Abstract. Species occurrence patterns, and related processes of persistence, colonization and turnover, are increasingly being used to infer habitat suitability, predict species distributions, and measure biodiversity potential. The majority of these studies do not account for observational error in their analyses despite growing evidence suggesting that the sampling process can significantly influence species detection and subsequently, estimates of occurrence. We examined the potential biases of species occurrence patterns that can result from differences in detectability across species and habitat types using hierarchical multispecies occupancy models applied to a tropical bird community in an agricultural fragmented landscape. Our results suggest that detection varies widely among species and habitat types. Not incorporating detectability severely biased occupancy dynamics for many species by overestimating turnover rates, producing misleading patterns of persistence and colonization of agricultural habitats, and misclassifying species into ecological categories (i.e., forest specialists and generalists). This is of serious concern, given that most research on the ability of agricultural lands to maintain current levels of biodiversity by and large does not correct for differences in detectability. We strongly urge researchers to apply an inferential framework which explicitly account for differences in detectability to fully characterize species-habitat relationships, correctly guide biodiversity conservation in human-modified landscapes, and generate more accurate predictions of species responses to future changes in environmental conditions.

e Rogério Hartung Toppa 4 RESUMO -O principal objetivo deste estudo foi diagnosticar o cenário ambiental atual e um cenário legal da Zona de Amortecimento (ZA) do Parque Estadual de Porto Ferreira (PEPF), bem como propor uma discussão acerca das ZA e seu planejamento. Foi realizado um mapeamento do uso e ocupação da terra e calculadas métricas de paisagem. A classe predominante na ZA foi a cana-de-açúcar, com 46,24%; e a classe floresta foi a terceira com maior cobertura, com 12,7%. As métricas da paisagem indicaram que a vegetação natural da ZA possui 83,3% de fragmentos até 10 ha, com 50% deles apresentando conectividade muito baixa. As APP totalizaram 386 ha, sendo 39% com vegetação natural. Para o cenário legal, com todas as APP preservadas, haveria um acréscimo de 239 ha de vegetação natural e redução de 60 para 27 fragmentos, evidenciando-se o surgimento de fragmentos maiores e mais conectados. A baixa porcentagem de áreas florestadas, baixa conectividade entre os fragmentos e o descumprimento da legislação ambiental na ZA contribuem para o isolamento da unidade de conservação e aumento dos efeitos de borda, gerando impactos sobre a biodiversidade do PEPF.Palavras-chave: Área protegida; SIG; Fragmentação florestal.
