The aim of this study was to evaluate the concentrations of clenbuterol residues in the red hair of Chinese Simmental beef cattle following exposure to two doses of clenbuterol for 21 days. This experiment was conducted in six male red pied Chinese Simmental beef cattle which were randomly divided into two groups (n = 3). Groups 1 and 2 were administered clenbuterol at a dose of 16 and 48 μg/kg...

Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around pointsources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna. This thesis focuses on the effects on pied flycatcher populations o...

The parasite faunas of the black stilt (Himantopus novaezelandiae) and the pied stilt (H. h. leucocephalus ) in New Zealand were investigated.
