“…Concealed microhabitats may buffer edge-dwelling species from the increased unfavorable interactions that can occur in complex habitat fragments. For instance, edge-dwelling organisms often suffer greater predation rates than organisms in the core of habitat patches (Ferguson 2000;Purger et al 2004;Anderson and Burgin 2008). The choice of more concealed, structurally complex habitat to avoid detrimental encounters is prevalent among various taxa including spiders (Wise 2006;Manicom et al 2008), insects (Atlegrim 1989), fish and lobsters (Eggleston et al 1997) andbirds (Jenks-Jay 1982), and can have important consequences at the population and community levels (Holbrook and Schmitt 2002).…”

Increased edge effects in fragmented habitats can affect the abundance of edge-dwelling organisms, but these impacts may depend on the biological attributes of species. Microhabitat choice, a species characteristic that reflects combinations of biological traits, may affect the ability of peripheral species to take advantage of increased edge habitat in the presence of edge effects. In this field study, we built artificial shrub modules designed to encourage web spiders to build webs on the periphery. While modules were identical in volume, they differed in shape (cubic and elongated), so that elongated modules had more edge habitat and were subject to enhanced edge effects. Given that the tangle-web spiders Theridion and Dictyna built webs on module edges and strongly differed in terms of concealment and substrate generalization, two habitat characteristics associated with lower vulnerability to habitat modification, we tested the hypothesis that Theridion, which built webs in more concealed locations and on a greater diversity of substrate configurations in the modules compared to Dictyna, would take better advantage of increased edge habitat. As predicted, Theridion was significantly more abundant on elongated modules whereas the abundance of Dictyna did not respond to shape, even though the change in module shape entailed a similar increase in favored substrate for both spider groups. Our results suggest that the microhabitat associations of organisms may be linked to their propensity to be sensitive to edges, and that a better understanding of these links can improve our ability to predict the effects of habitat modification on biodiversity.

“…In the same recultivated area the survival chances of nests in the bush were significantly greater than of those in the forest edge. This was the case also when the nests contained only one plasticine or quail egg (Purger et al 2004). Santos & Telleria (1992) also found higher predation rates in forest patches than in agricultural land.…”

“…The northern part of the mine, covering approximately 15 hectares is recultivated. The covering layer is overgrown by herbaceous vegetation of the initial stage of primary succession (Purger et al 2004). The recultivated area is bordered from the east, north and west by Turkey Oak forests (Potentillo micranthae-Quercetum daleschampii Horvát A.O.…”

“…Não houve registro de ovos sintéticos desaparecidos e as marcas deixadas demonstram que os predadores tentaram consumir os ovos. Provavelmente por não ser palatável e devido a consistência os predadores abandonaram os ovos próximo aos ninhos (PURGER et al 2004) Os teiús podem ter contribuído para a alta taxa de ovos de codorna e de canário desaparecidos, pois a sua habilidade de engolir ovos inteiros já foi observada (MARINI & MELO 1998). Além disso, os teiús são conhecidos por serem vorazes predadores de ninhos em Fernando de Noronha (TEXEIRA et al 2003).…”

Experimentos com ninhos artificiais são utilizados para testar hipóteses ecológicas e comportamentais que influenciam na predação de ninhos naturais. O tamanho do ovo, a textura da casca e a cor podem influenciar na taxa de predação, porém poucos estudos avaliam qual modelo de ovo é o mais adequado para simular a predação de ninhos em áreas tropicais. O objetivo deste trabalho foi comparar a predação de diferentes modelos de ovos (ovos de codorna, massa de modelar e canários) no solo e a 1,30 m de altura no sub-bosque. O experimento foi realizado Ilha Anchieta, Ubatuba, São Paulo, Brasil. Foi encontrada uma diferença significativa na taxa de predação entre os ovos de codorna (71,87%) e sintéticos (93,75%) e entre os ovos de codorna e de canário (100%) no solo. Entretanto, não houve diferença significativa entre os ovos sintéticos e de canário. Os ninhos no sub-bosque apresentaram um padrão diferenciado do solo quando se refere aos ovos de codorna (25%) e sintéticos (28,1%), mas houve diferenças significativas quando os ovos de canário foram comparados com os ovos sintéticos e de codorna. Nosso trabalho demonstrou que diferentes tipos de ovos sobre uma mesma pressão de mesopredadores apresentaram taxas de predação diferentes. Portanto, estudos que avaliam o sucesso reprodutivo da avifauna baseado na predação de ninhos artificiais devem considerar a utilização de diferentes tipos de ovos e estratos na vegetação.
