The status of species currently assigned to the Southeast Asian Elephant Pupinid snail genus Pollicaria Gould, 1856 is reassessed. Shell, radular and reproductive morphology are investigated and analysed with reference to karyotype patterns previously reported and to distribution patterns among the species. Six previously described species are recognised: Pollicaria gravida (Benson, 1856), Poll...
Woody vegetation spread over former croplands in Europe has created new unexploited habitats for forest organisms. Their ability to colonise them and thrive depends on life-history traits including fecundity, dormancy dispersal ability. The effects of these species distribution, abundance community assembly have been extensively studied fragmented landscapes. However, their consequences genetic...
Palinurids, also known as spiny lobsters, are high-value seafood, which is economically important for many European and Asian seafood trades. However, the reduction of wild lobster populations produces a need developing alternative renewable strategies to meet current future demands. Aquaculture lobsters has potential become major economic importance in coming years with growing markets Asia, E...
Faecal samples were collected from 40 Indian elephants (Elephas maximus) revealed 62.5 percent parasitic prevalence. Amongst the single infection of parasites, high prevalence of Fasciolias spp. (15.00 %) was observed followed by percent prevalence of mixed infection. Elephants harbouring parasites were found clinically dull, depressed and lethargic. About 48 percent elephants manifested dehydr...
Elephant beetles (Megasoma elephas; Scarabaeidae) weighing from 10 to 35 grams, respond homeothermically when ambient temperature is reduced below about 20 degrees C in the laboratory. This metabolic response is not associated with locomotion or any other overt activity. Warming is initiated when the body temperature reaches an apparent set point of 20 degrees to 22 degrees C. Unlike the case f...
Construction of age structures of populations is central to studies of demography of large vertebrates (Caughley 1977). Unlike in the case of the African elephant (Loxodonta africana), there are few published age structures of wild Asian elephant (Elephas maximus) populations (Sukumar 1989, 2003). On the other hand, age/sex structures for several Asian elephant populations are available in repo...
