The genetic affinity of the three tribes, two belonging to Kuruba/Kurumba cluster (viz. Jenu Kuruba and Betta Kuruba) and the third (viz. Soliga tribe)immediate neighbor of the first two but not the part of Kuruba/ Kurumba cluster has been studied using ten polymorphic genetic markers. To investigate, whether all the Kuruba/ Kurumba groups are related to the Pallava dynasty and are the off shoo...

Severe bark decay disease was observed on oak logs at a shiitake cultivation farm in Geochang-gun, Gyeongnam province. The symptoms observed were fruiting bodies that had developed on the top and side surface of oak logs. As a result, the bark came off easily exposing the sapwood. Slime mold specimens collected from oak logs showed developing fruiting bodies comprising of stalks, hypothallus, c...

Acute toxicity tests were conducted to measure the response of first instar Toxorhynchites splendens to commonly used mosquito adulticides: malathion, naled and resmethrin. The concentrations of pesticide causing 50% mortality (LC50) after 24 h was 2.87, 69.1 and 623 ppb for resmethrin, malathion and naled, respectively. Naled was determined to be the least toxic of the 3 compounds tested for i...

The reproductive activity of Biomphalaria glabrata exposed to Euphorbia splendens var. hislopii latex was evaluated. Parameters related to fecundity and fertility were observed. The snails were exposed to the LD50 (1 mg/l) of crude latex. At the first week post exposure (p.e.), the egg laying was reduced. After the fourth week p.e., an increase of the number of eggs/snail occurred. The results ...

there are various factors affecting the fighting fish larval survival including nutrition, substrate, water quality, pathogen and stress. experiments were conducted to study the effect of substrate and live feed on larval survival of fighting fish fry. nine small glass aquaria (60 cm × 30 cm × 30 cm) were used as breeding tanks. equal pieces (80 cm2) of rigifoam (t1), polythene (t2) and banana ...

Aggressive signalling interactions contain information that could be used by individuals other than those directly involved in the interaction. We investigated whether the relative information contained in such signalling interactions is used by others in a laboratory setting. Male fighting fish (subjects) were allowed to see three treatments, without themselves being seen. In the control treat...
