Convergent evolution is a widespread phenomenon seen in diverse organisms inhabiting similar selective environments. However, it is unclear if similar phenotypes are produced by the same or different genes and mutations. Here we analyze the molecular mechanisms underlying convergent pigment pattern among subspecies of the beach mouse (Peromyscus polionotus) inhabiting the Gulf and Atlantic coas...

An oil spill occurred off Goa, west coast of India, on 23 March 2005 due to collision of two vessels. In general, fair weather with weak winds prevails along the west coast of India during March. In that case, the spill would have moved slowly and reached the coast. However, in 2005 when this event occurred, relatively stronger winds prevailed, and these winds forced the spill to move away from...

This research demonstrates a diasporic connection between slavery on both sides of the Atlantic, English and African interactions on the Gold Coast, and slave resistance in Jamaica from 1655 to the middle of the eighteenth century. This article transfers the site of ‘seasoning,’ the process by which enslaved peoples became physically and socially acclimatised to slavery, from New World plantati...

Three hundred and thirty two species of polychaetes belonging to 50 families are reported for Costa Rica based on previously published reports. In a few families, available material was re-examined and appropriate changes in species identifications were made. Only three species, (Glycera oxycephala Ehlers, 1887; Hemipodia pustulata (Friedrich 1956); and Scolepis (Scolepis) squamata (Miller, 180...

STOCK DEFINITION AND GEOGRAPHIC RANGE The gray whale formerly occurred in the North Atlantic Ocean (Fraser 1970), but is currently only found in the North Pacific (Rice et al. 1984). The following information was considered in classifying stock structure of gray whales based on the Dizon et al. (1992) phylogeographic approach: 1) Distributional data: isolated geographic distribution in the Nort...

The health of an organism depends on its self protective ability. The regulatory enzyme, biomarkers measurable changes have been used as an effective early warning tool in ecological risk assessment. In order to develop an integrated risk assessment strategy for the South east coast of India. The green mussels Perna viridis were collected from three sites along the southern east coast with diff...
