“…Within these distribution limits, two environmental GIS layers, habitat and elevation, were combined with the occurrence data to predict the areas of occupancy with respect to these two variables, as in Jennings and Veron (2011) . We used a 2010 land cover map (250-m resolution) for Southeast Asia (http:// www.eorc.jaxa.jp/SAFE/LC_MAP/; Miettinen et al 2012 ) that was reclassified to eight cover classes (evergreen forest, peatswamp forest, mangrove, plantation, mosaic, open areas, water and urban).…”

“…Presence-only ecological niche modelling (ENM) can be a useful tool for predicting the distributions of poorly known species in remote and inaccessible regions (Gaubert et al 2006, Papes and Gaubert 2007, Wilting et al 2010, Jennings and Veron 2011, Jenks et al 2012. The outputs of ENM can aid conservation planning by highlighting potential unknown populations and key areas for fieldwork and conservation initiatives (Peterson 2006 , Thorn et al 2009 , Jackson andRobertson 2011 ).…”

“…Although the lack of species records from regions of predicted presence can be simply an artefact of inadequate sampling effort, unoccupied areas might highlight instances where other factors, such as biogeographical and ecological barriers or interspecific competition, have played a role in restricting the range of a species (Phillips et al 2006 , Jennings andVeron 2011 ). Species persistence in predicted areas may also be influenced by humaninduced factors, such as habitat loss and hunting (Corlett 2007, Thorn et al 2009 ).…”

“…Using Maxent ENM software ; http:// www.cs.princeton.edu/~schapire/maxent/), we predicted the distributions of these two viverrids by combining accurately recorded occurrence data with two environmental variables, habitat and elevation, that have key distribution and conservation implications for mammal species (Catullo et al 2008, DeMatteo and Loiselle 2008, Brito et al 2009, Jennings and Veron 2011, Rondinini and Boitani 2012. Maxent has been shown to perform better than other ENM approaches (Elith et al 2006 ), especially with low numbers of occurrence data Gaubert 2007 , Pearson et al 2007 ), and it also produces continuous suitability estimates that are useful for indicating high priority areas for surveying and conservation planning (DeMatteo andLoiselle 2008 , Wilting et al 2010 ).…”

Knowledge of the distribution and habitat preferences of a species is of paramount importance when assessing its conservation status. We used accurately recorded occurrence records and ecological niche modelling to predict the distribution of two threatened and poorly known small carnivore species that occur in Southeast Asia, the banded civet ( Hemigalus derbyanus ) and Hose ' s civet ( Diplogale hosei ), and analysed their spatial niche differentiation for habitat and elevation. We then identified possible anthropogenic threats, and used our modelling predictions to recommend surveying priorities. The predicted distribution of the banded civet was principally in lowland evergreen forest in southern Myanmar/Thailand, Peninsular Malaysia, Sumatra, Borneo and three Mentawai Islands (Siberut, Sipora and South Pagai), and for Hose ' s civet in evergreen forest across the higher elevation regions of Borneo. Our niche analyses suggested that there is a tendency for these two species to separate spatially along an elevation gradient: the banded civet is mainly found in lowland areas, whereas Hose ' s civet primarily occurs at higher elevations. Our study strongly indicated that these two viverrids are forest-dependent species that may be threatened by forest loss, degradation and fragmentation. Field surveys should be prioritised in areas where each species is predicted to occur and no records currently exist.

“…We used MaxEnt because it performs better than other presence-only modeling techniques (Elith et al 2006 ), especially with low numbers of occurrence locations (Papes and Gaubert 2007 ). This method has been used to develop habitat suitability models for a range of mammals (e.g., DeMatteo and Loiselle 2008 , Monterroso et al 2009, Wilting et al 2010, Jennings and Veron 2011.…”

No recent attempt has been made to survey dhole distribution, or to estimate remaining population numbers. We surveyed 15 protected areas in Thailand with camera traps from 1996 to 2010. We used the photo locations of dholes (n = 96) in the maximum entropy (MaxEnt) model along with six environmental variables to model current dhole distribution, as well as species predictive occurrence layers for sambar, red muntjac, wild boar, tiger, and leopard. The MaxEnt model identifi ed the predicted probability of the presence of leopards and sambar as positive and the most important variables in modeling dhole presence, indicating that maintaining a suffi cient prey base may be the most important factor determining continued survival of dholes. Roughly 7 % of the total land area in Thailand is potentially suitable for dholes. However, surveys to date have focused on protected areas, which make up just a third of the potential suitable areas for dholes. Only in four protected areas do they occur across the entire landscape, suggesting that in the majority of places where they occur, habitats are not uniformly suitable. Using the model, we identifi ed several potential areas where dholes have not been reported, and therefore status surveys are needed, and where future research of the species might be focused.
