“…In recent years, the island of Borneo in South-East Asia has undergone some of the highest deforestation rates in the world (Achard et al 2002, Sodhi et al 2010. These have reduced it to a patchwork of land-uses consisting mostly of logged secondary forests and fragmented agricultural landscapes, with very few expanses of old-growth forest remaining outside of protected areas (Bryan et al 2013, McMorrow & Talip 2001.…”

Influence of microhabitat structure and disturbance on detection of native and non-native murids in logged and unlogged forests of northern Borneo

Abstract:Understanding the habitat preferences of native and non-native species may offer valuable insights into the mechanisms favouring invasion of disturbed habitats. This study investigated the determinants of trap-site detection probability of three native (Maxomys surifer, Maxomys whiteheadi and Leopoldamys sabanus) and one invasive (Rattus rattus) species of terrestrial murid (Muridae) in logged and unlogged forests of northern Borneo. We established four and two trapping grids in repeatedly logged and unlogged forest, respectively, for a total of 500 sampled trap sites. From these, we obtained 504 detections of the four species over 3420 trap nights. For each species, probability of detection was modelled as a function of both the structural components and disturbance level of the forest patch measured around each trap site. Each of the four species showed contrasting microhabitat preferences: M. surifer favoured increased canopy closure and intermediate ground and understorey vegetation cover; M. whiteheadi preferred increased ground vegetation cover and canopy height; L. sabanus favoured sites with larger amounts of coarse woody debris and less leaf litter; and R. rattus was associated with increased ground vegetation cover. Within logged forest, detection probabilities of the three native species did not vary significantly with level of patch disturbance, whereas that of the invasive R. rattus increased markedly in more degraded sites. This latter finding will have increasingly important implications when considering the rapid degradation of forests in the region, and the resulting expansion of suitable habitat for this competitive species.

“…Second, there is a need for more research in Southeast Asian disturbed forests. The region is a biodiversity hotspot and is highly threatened by deforestation (Sodhi et al, 2004(Sodhi et al, , 2010. However, research on forest recovery here is comparatively lacking as compared to that in the Neotropics, and past research has largely focused on the early stages (1-15 years) of forest recovery (Jepsen, 2006;Nykvist, 1996;Ohtsuka, 1999Ohtsuka, , 2001Slik et al, 2002;Yassir et al, 2010, but see Brearley et al, 2004;Turner et al, 1997).…”

“…Lowland tropical evergreen forests in South-East Asia are among the most species-rich biomes in the world and support a high proportion of endemic biodiversity (Sodhi et al 2004a(Sodhi et al , 2010. However, these forests are subject to the highest relative rates of deforestation and degradation anywhere in the humid tropics (Achard et al 2002) owing largely to agriculture and commercial logging (Lambert & Collar 2002, Sodhi & Brook 2006, and results in a patchwork landscape of forest fragments (Wright 2005).…”

Do insectivorous bird communities decline on land-bridge forest islands in Peninsular Malaysia?

Abstract:To assess the impact of habitat fragmentation on tropical avian communities, we sampled lowland forest birds on six land-bridge islands and two mainland forest sites in Lake Kenyir, Peninsular Malaysia using timed point counts, hypothesizing that insectivorous birds are the worst affected guild. We used an information-theoretic approach to evaluate the effects of area, isolation, primary dietary guild (omnivore, frugivore and insectivore) and their interactions in predicting species richness, abundance and diversity. Our analysis showed that a model that considered the effects of area, dietary guild and their interaction best explained observed patterns of species richness. But a model considering both area and dietary guild best explained the variation in abundance. Notably, insectivorous birds were singled out as the dietary guild most sensitive to fragmentation, followed by frugivorous and omnivorous birds and hence provide support for our hypothesis. Assemblages of insectivorous birds were clearly depauperate on anthropogenic forest islands in Lake Kenyir and are consistent with forest fragmentation studies in the Neotropics. Given their specialized foraging ecology and diversity, conservation of intact communities of insectivorous bird guilds in Malaysia will be critical for maintaining predator-prey interactions in lowland tropical forests.
