Selected AbstractsA review of the catfish genus Pterocryptis (Siluridae) in Vietnam, with the description of two new speciesJOURNAL OF FISH BIOLOGY, Issue 3 2001H. H. Ng Of the silurid catfish genus Pterocryptis in Vietnam, a total of four species are recognized as valid, of which Pterocryptis crenula and P. verecunda are described here as new. The type locality of P. cochinchinensis is restricted to central Vietnam, and the species is redescribed from topotypic material. Pterocryptis crenula (from northeastern Vietnam) can be differentiated from its congeners in having visibly confluent anal and caudal fins while P. verecunda (from Cat Ba Island in northeastern Vietnam) can be differentiated from its congeners in having the genital papilla concealed behind the anus. Notes on the identity of other nominal Pterocryptis species are also provided.

Leong Abstract Aims:, To determine the incidence and severity of infection by ochratoxin A (OA)-producing fungi in Vietnamese green coffee beans. Methods and Results:,Aspergillus carbonarius, A. niger and yellow Aspergilli (A. ochraceus and related species in section Circumdati) were isolated by direct plating of surface-disinfected Robusta (65 samples) and Arabica (11 samples) coffee beans from southern and central Vietnam. Significantly, more Robusta than Arabica beans were infected by fungi. Aspergillus niger infected 89% of Robusta beans, whereas A. carbonarius and yellow Aspergilli each infected 12,14% of beans. OA was not produced by A. niger (98 isolates) or A. ochraceus (77 isolates), but was detected in 110 of 113 isolates of A. carbonarius, 10 isolates of A. westerdijkiae and one isolate of A. steynii. The maximum OA observed in samples severely infected with toxigenic species was 1·8 ,g kg,1; however, no relationship between extent of infection and OA contamination was observed. Conclusions:,Aspergillus niger is the dominant species infecting Vietnamese coffee beans, yet A. carbonarius is the likely source of OA contamination. Significance and Impact of Study:, Vietnamese green coffee beans were more severely infected with fungi than the levels reported for beans from other parts of the world, yet OA contamination appears to be infrequent. [source] The stripe-backed weasel Mustela strigidorsa: taxonomy, ecology, distribution and statusMAMMAL REVIEW, Issue 4 2008A. V. ABRAMOV ABSTRACT 1The stripe-backed weasel Mustela strigidorsa is one of the rarest and least-known mustelids in the world. Its phylogenetic relationships with other Mustela species remain controversial, though several unique morphological features distinguish it from congeners. 2It probably lives mainly in evergreen forests in hills and mountains, but has also been recorded from plains forest, dense scrub, secondary forest, grassland and farmland. Known sites range in altitude from 90 m to 2500 m. Data are insufficient to distinguish between habitat and altitudes which support populations, and those where only dispersing animals may occur. 3It has been confirmed from many localities in north-east India, north and central Myanmar, south China, north Thailand, north and central Laos, and north and central Vietnam. Given the limited survey effort, the number of recent records shows that the species is not as rare as hitherto believed. Neither specific nor urgent conservation needs are apparent.

Biogenetically, haperforin D and haperforin B1 can be derived from each other by addition or elimination of water. [source] | ||||||||||
