The Wujiang River is a tributary of the upper Yangtze River that shows great variations in its flow regime and habitat condition. Dams have been built along the Wujiang River and have altered the habitats profoundly enough that they may give rise to reproductive isolation. To test whether the swimming performance and morphology of the Chinese hook snout carp (Opsariichthys bidens), varied among...

The study aimed to investigate the potential in vitro antihelicobacter activity of selected Egyptian plants, focusing on the determination of the main component responsible for such activity. The main objective is to obtain a natural product have antihelicobacter activity. Antimicrobial screening for wild Egyptian medicinal plant extracts, revealed that five methanolic extracts have good antihe...

Metabólitos secundários atuam como mecanismos de defesa espécies vegetais, na adaptação ao meio, nos processos polinização e dispersão sementes, sendo também estudados explorados para a produção fitoterápicos e, em um cenário contemporâneo, bioherbicidas ou biofertilizantes. Nesse contexto, este estudo objetivou avaliar o potencial alelopático Zingiber officinale Roscoe sobre germinação, emergê...

Several species of Orius Wolff are used in biological control of thrips in protected cultivations in temperate regions, but some of them show reproductive diapause, compromising the efficiency of these agents of biological control. There are no reports on the biology of the neotropical species Orius thyestes Herring under different environmental conditions. The purpose of this work was to inves...

OBJECTIVES Bidens species are used for their antidiabetic properties traditionally in many countries. Aim of this study is to evaluate hypoglycaemic and antidiabetic activity of Bidens tripartita extract and to identify its active compounds through bioactivity guided isolation technique. MATERIALS AND METHODS Hypoglycaemic effects of B. tripartita extract and its sub-extracts were investigate...

To understand germination timing in an ecological context, the response to environmental events that affect seed dormancy is central, and has to be combined with knowledge of germination responses to different circumstances. In this study, seed dormancy, germination, and emergence phenology of six annual co-occurring weedy Asteraceae species were investigated. Three pre-treatments (warm and col...
