Article
Insects as a group are suffering rapid declines in many parts of the world but are also poorly studied relative to vertebrate taxa. Comprehensive assessments of insect declines must account for both detected and undetected species. We studied extirpations among butterflies, a particularly well-known insect group, in the highly developed and biologi...

Spatial capture–recapture (SCR) models have emerged as a robust method to estimate population density of mobile animals. However, model evaluation has generally been based on data simulated from simplified representations of animal space use. Here, we generated data from animal movement simulated from a mechanistic individual‐based model, in which...

Since Fraser and Bernatchez's seminal paper, the concept of adaptive conservation has inspired in situ and ex situ management aimed at preserving the genetic distinctiveness of natural populations and their associated evolutionary potential. This goal is particularly worthwhile in an epoch of rampant biotic homogenisation (i.e., the progressive rep...

The Nee Soon stream drainage in the Central Catchment Nature Reserve is virtually the last remaining fragment of primary freshwater swamp forest in Singapore. The forest type has been poorly studied in the Southeast Asia. The hydrology, water quality, as well as aquatic flora and fauna all have great theoretical and practical significance. The ecol...
Article
The Critically Endangered saiga antelope Saiga tatarica faces an uncertain future, with populations dwindling from epidemics in its range countries, and ongoing demand for its horns in the traditional Chinese medicine trade. Singapore is a major hub for the global trade in saiga horn and an important consumer country, with saiga horn products widel...

This study is an analysis of records of the seizure of otters by law enforcement agencies in selected Asian countries between 1980 and July 2015. The study was undertaken to understand the extent and scale of the illegal otter trade in Asia, and focussed on four Asian otter species i.e., the eurasian otter (Lutra lutra), hairy-nosed otter (Lutra su...

We investigated the phylogeography of the smooth-coated otter (Lutrogale perspicillata) to determine its spatial genetic structure for aiding an adaptive conservation management of the species. Fifty-eight modern and 11 archival (dated 1882–1970) otters sampled from Iraq to Malaysian Borneo were genotyped (mtDNA Cytochrome-b, 10 microsatellite DNA...
Book
Full-text available
Aquatic macroinvertebrates and lower vertebrates were surveyed from the last remaining freshwater swamp forest in Singapore. Ecological data was collated from three years of field work. This book is a guide to the macroinvertebrates and the fish of the Nee Soon Swamp Forest, with identification keys provided as well.

After decades of absence, the smooth-coated otter Lutrogale perspicillata (Geoffroy, 1826) is now widespread along the northern shores of Singapore. Their diet was examined at four sites along the northern coast, through an analysis of 181 spraint samples, which revealed a diet mostly of fish (92%) and prawns (8%). Dietary composition differed amon...

The illegal wildlife trade poses a direct threat to all four species as they are popular for their fur and increasingly for their supposed qualities as pets. This study is an analysis of otter seizure data during the period 1980 to July 2015 inclusive. This study was born out of a desire to understand the extent and scale of the trade involving all...
Article
Full-text available
The smooth-coated otter Lutrogale perspicillata reappeared in Singapore in the mid-1990s after an apparent absence of three decades. No assessment of their status has been reported since. We compiled 370 sighting records from the literature and verified online reports and submissions between 1998 and 2014. The records revealed increasing numbers of...
