ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.

ABSTRACT Climbing perch, Anabas testudineus, were fed four diets: D0, D500, D1000 and D1500, containing 0, 500, 1000 and 1500 mg of vitamin C per kg of basal diet, respectively, over 70 days. After the growth trial, significantly higher final weight, percent body weight (%WG) and specific growth rate (SGR) were observed in fish fed D1000 followed by ...

Unlocking the Secrets of Sturgeon Ecology: Lessons From Conservation Efforts in Northern Italy
ABSTRACT This study aimed to investigate the ecology of the Adriatic sturgeon (Acipenser naccarii) and Beluga sturgeon (Huso huso) in the Po basin in northern Italy, where both species have faced significant population declines. Using data collected from three LIFE projects, we investigated movement behaviour and habitat selection of the species ...

An Accurate Method for Measuring Activation Energy [PDF]
In this letter, we present an accurate method for the measurement of activation energy. This method combined the excitation power dependent photoluminescence and temperature dependent photoluminescence together to obtain activation energy. We found with increasing temperature, there is a step transition from one emission mechanism to another. This step
