The strategies of metal tolerance developed by several plants that enable them to survive in metal contaminated and polluted sites. Some of them may accumulate significant concentration of a specific element. The work presented here is part of the on going study in Central Portugal, and it focus only in a preliminary description. We have observed that Apium nodiflorum, Callitriche stagnalis, Le...

Studies on bioecology of An. philippinensis a vector of malaria was carried out in eight islands of the Andaman group. It was found that An. philippinensis preferred to rest and bite outdoors. Maximum biting was observed during 1800 to 2100 hrs on both cattle and human bait. The maximum breeding of An. philippinensis was recorded in slow moving stream followed by ponds with vegetation. The bree...

The aim of the present study was to introduce an alternative way for insects control through biodegradable plants materials. The different cold water extracts dilutions of Acacia modesta and Glycyrrhiza glabra were tested against Tribolium castaneum. The extracts dilutions of both plants caused mortality of the Tribolium castaneum. ANOVA revealed that dilutions and plants were highly significan...

IIn June 2021, parasitism by leeches of the genus Helobdella was observed for first time in Hyla eximia during an irrigation canal monitoring. This event occurred shortly after canals were opened to supply agroecosystem The Cerrillo, Piedras Blancas, Toluca de Lerdo, State Mexico, Mexico. frog trapped one beds, which had abundant presence duckweed (Lemna minor). We analyzed load and distributio...

Plant nutrients extracted from sustainable sources, namely Alaria esculenta and Lemna minor, have been evaluated for their nutritional value in an attempt to identify potential as protein-rich sources. The implementation of green technologies such high-power ultrasound extract these alternative biomasses was studied compared more traditional techniques. Probe sonicators fared better than bath e...
