– Extensive field collections of small alpheid shrimps in Sungei Buloh and Lim Chu Kang mangroves in Singapore, along with the examination of preserved material, yielded two new species and several new records for South-East Asia and Australia. The description of Salmoneus singaporensis, new species, is based on a single specimen from Singapore, which differs only slightly from the rarely colle...

234 * To whom correspondence and reprint requests should be addressed. Ophiuroids are among the most common and conspicuous macro-invertebrates in shallow water habitats. Many species live in association with larger invertebrates, such as sponges, corals and other echinoderms (e.g., Baker et al. 2001, Tominaga et al. 2004, Henkel and Pawlik 2005). However, ophiuroids themselves may serve as hos...

The survival of many organisms depends on interspecific, mutualistic interactions. Hence, it is important to assess the phylogeography of multiple mutualistic species simultaneously to gain insight into how their metapopulations persist, spread and recover from disturbance. Consequently, we sequenced mitochondrial DNA (cytochrome b) from a gobiid fish (Ctenogobiops feroculus) and its mutualisti...
