Background. Background matching, as a camouflage strategy, is one of the most outstanding examples of adaptation, where little error or mismatch means high vulnerability to predation. It is assumed that the interplay of natural selection and adaptation are the...

Background Biological oxidation of methane (CH4) is an essential ecosystem function. Accumulating evidence indicated that this function is mediated by associations of methanotrophic bacteria (MOB) with non-methanotrophic partners; together referred to as a methanotrophic...

Pyrrolizidine alkaloids (PAs), a typical kind of secondary metabolites in plants, have important roles on defense against herbivores and pathogens; however, specialist herbivores adapted to PAs can use them as cues for oviposition and feeding. Thus, in the native...

According to the Evolution of Increased Competitive Ability (EICA) hypothesis and Enemy Release Hypothesis (ERH), comparing the plants from the same species, individuals from the invasive range will outperform those from the native range. However, not all recent...

Homalozoa are a weird group of echinoderms, for their complete lack of radiate symmetry. Indeed, they are typified by their tendency to marked asymmetric body forms. It has been proposed that they asymmetric forms evolved from bilaterally symmetric ones, but so...
