Saproxylic insect communities inhabiting tree hollow microhabitats correspond with large food webs which simultaneously are constituted by multiple types of plant-animal and animal-animal interactions, according to the use of trophic resources (wood- and insect-dependent sub-networks), or to trophic habits or interaction types (xylophagous, saprophagous, xylomycetophagous, predators and commens...

The communication systems of nonhuman animals are reviewed, together with a discussion of their relevance for the evolution of human language. The teaching of language to nonhumans, as well as signs of mind and consciousness outside our species, are considered as possible bridges between us and the rest of the animal kingdom.

It is often argued that pigs raised under less intensive production conditions - such as organic or free-range - have a higher level of animal welfare compared with conventionally raised pigs. To look into this, an analysis of data from a large Danish abattoir slaughtering organic, free-range, and conventionally raised finishing pigs was undertaken. First, the requirements for each of the three...

Background: Clostridium perfringens is known as the most widely distributed pathogenic microorganism in nature. It is an extremely important pathogen of human and domestic animals. In a commonly used classification scheme, C. perfringens is divided into five toxinotypes (A to E) based on the production of four major toxins (alpha, beta, epsilon, and iota). Enterotoxin is not usually used for C....
