Invasive species impact both the local biota and human economies and are a very serious threat to biodiversity. The American bullfrog was initially introduced into northwestern China and many other sites for aquacultural purposes. Then, the frogs escaped and established feral populations. Here, we investigated the variations in age, body size, and...

Nesting-site selection is an important aspect of the breeding process in birds, as it usually determines nesting and breeding successes. Many factors can affect bird nest-site selection, including anthropogenic disturbance. In an extreme desert environment, such as the Taklamakan Desert in China, birds’ survival pressure is high, especially for rar...

Egg size represents maternal investment and is an important life-history trait. It also is assumed to have an effect on offspring fitness. Life-history theory predicts that oviparous animals on islands will produce enlarged eggs because of increased maternal investment to improve offspring performance to facilitate intra-specific competition. The l...

Question
I would like to study food habits of some small and middle size birds. I want to find methods to research several individuals' food habits several times and then compare. Does anyone have some suggestions for my work?
Question
Except the directly negative effect such as the road collision, what kind of effects can the road or traffic have on the wild animals? I have noticed the road collision and habitat fragment. Now I want to know more effects of methods or references on this field.
