The plant Nierembergia hippomanica var. violacea has been incriminated in field outbreaks of neurotoxicity in calves in the Free State Province. Hepatotoxicity and electrocardiogram (ECG) deviations were induced in a sheep dosed with 5 g/kg dried plant material on four consecutive days. A calf dosed with 2.5 g/kg dried plant material, on two consecutive days, did not show overt clinical changes...

Aurelia coerulea , a type of scyphozoan jellyfish, has massively appeared in the coastal waters China recent years and caused great damage, but asexual reproduction A. polyp predicted by local temperature could not correspond well to field abundance jellyfish summer. To understand influence winter spring conditions on reproductive process provide basis for population prediction, polyps, origina...

This study aims to identify the remnant tree flora in six forest fragments in the metropolitan area of Belém and to analyze these fragments in terms of biological conservation, species richness and diversity in the local urban landscape. The fragments and their respective sampling areas were as follows: Amafrutas reserve (15 ha), Trambioca Is. reserve (2 ha), Bosque Rodrigues Alves city park (1...

Species delimitation of corals is one the most challenging issues in coral reef ecology and conservation. Morphology can obscure evolutionary relationships, molecular datasets are consistently revealing greater within-species diversity than currently understood. Most phylogenetic studies, however, have examined narrow geographic areas phylogeographic expansion required to obtain more robust int...
