In this paper, we describe the seasonal dynamics of three common microcystins (MCs; MC-RR, MC-YR, and MC-LR) in the whole body, hepatopancreas, intestine, gonad, foot, remaining tissue, and offspring of a freshwater snail, Bellamya aeruginosa, from Gonghu Bay of Lake Taihu, China, where dense toxic Microcystis blooms occur in the warm seasons. Microcystins were determined by liquid chromatograp...

This paper describes seasonal changes of microcystin-LR (MC-LR) and its glutathione (MC-LR-GSH) and cysteine conjugates (MC-LR-Cys) in three aquatic animals--snail (Bellamya aeruginosa), shrimp (Macrobrachium nipponensis) and silver carp (Hypophthalmichthys molitrix) collected from Lake Taihu, China. MC-LR, MC-LR-GSH, and MC-LR-Cys were determined by liquid chromatography electrospray ionizatio...

The leopard cat ( Prionailurus bengalensis ) is the most widespread feline in Asia. It has been recorded a range of habitats, including monoculture landscapes, such as oil palm plantations.

The aim of this study was to evaluate the coffee germplasm of the Paraná Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of less damaged genotypes in the field were evaluated under controlled condition with obligated and free choice experiments established in a randomized complete design with three re...

Predator-induced defenses are well-known adaptive responses found in many marine and freshwater organisms. These responses usually occur in juveniles or actively growing adults and reduce the ability of a predator to consume its prey. We report a predator-induced response occurring in utero in the viviparid snail Bellamya chinensis (Gray, 1863) that results in significant changes in offspring n...
