Very large area requirements for frugivorous birds in monsoon rainforests of the Northern Territory, Australia

Reproductive traits of tropical rain-forest trees in New Caledonia

“…This species is apparently largely restricted to upland forests where it is in decline as a result of hunting. It is also likely that the fragmentation of rain-forest into small patches is highly deleterious for D. goliath populations, as it evidently is for D. bicolor Scopoli in the monsoon tropics of Australia (Price et al 1999).…”

Landscapes without boundaries: wildlife and their environments in northern Australia

“…This system was examined in a multidisciplinary study involving assessment of phenological patterning across a network of rainforest patches (Bach 2002), of temporal variation in the abundance of frugivorous birds and bats in those same patches over the same period (Palmer and Woinarski 1999;Palmer et al 2000), of the movement patterns of these species among patches and into the broader non-rainforest landscape (Price et al 1999;Price 2004), and of the dispersal pattern of seeds of rainforest plants that used these vertebrates as dispersal agents (Shapcott 1998(Shapcott , 1999(Shapcott , 2000. Although each rainforest patch was coarsely similar in structure and floristics, the patterning and amount of the fruit resources of each patch varied idiosyncratically (such that frugivores had to track the landscape-wide system of patches) and the variability among patches served to muffle the general moredeterministic pattern of seasonal highs and lows.…”

“…Although each rainforest patch was coarsely similar in structure and floristics, the patterning and amount of the fruit resources of each patch varied idiosyncratically (such that frugivores had to track the landscape-wide system of patches) and the variability among patches served to muffle the general moredeterministic pattern of seasonal highs and lows. The study included modelling of management actions, notably concluding that there were so many interdependent linkages that loss of any patch (such as through land-clearing) would reverberate across the network as a whole, and that very large areas of intact vegetation, including the rainforest patches and the broader landscape in which these were embedded, were required for the persistence of any of the frugivorous species (Price et al 1999).…”

Composição e estrutura da comunidade de aves na paisagem fragmentada do Pontal do Paranapanema

“…Têm sido ressaltados, sobretudo, os efeitos do tamanho e da borda dos fragmentos (Karr, J. R. 1982;Murcia, 1999;Mesquita et al, 1999;Price et al 1999;Crooks et al, 2000;Debinski & Holt, 2000), do grau de isolamento e conectividade (Taylor et al, 1993;Beier and Noss, 1998;Tischendorf & Fahrig, 2000;Bélisle, 2005;Uezu et al, 2005;Pardini et al, 2005;Damschen et al, 2006), da proporção de habitat Fahrig, 2002;; e, adicionalmente, são levantadas características das espécies que podem torná-las mais ou menos sensíveis à fragmentação Newmark, 2001;Henle et al, 2004). No entanto, esses estudos normalmente envolvem amostragens dentro de uma mesma região geográfica, removendo o efeito dessa variável, enfocando naquelas que se tem interesse em testar.…”
