Hence, a unit on ecology essentially requires students to memorize the vocabulary of various aspects of ecology such as levels of organization, ecological succession, feeding relationships, basic biomes, and the material cycles, with perhaps a bit of human impact thrown in, and then move on after a week or possibly two, at the most.
To estimate the number of ecological shifts that have occurred during the radiation of the Higher Nematinae, we first identified all distinct ecological niches (feeding habit × host plant(s)) found in the ingroup species included in the phylogenetic analysis, and coded each niche with a separate state within a single character (outgroup states were coded as unknown).
Of the possible traits involved in ecological speciation, feeding morphology has been shown to play a role in a wide array of taxa [ 2, 13- 18].
Promoted by the discovery of taste receptor genes, the evolutionary history of taste perception under certain ecological and feeding behaviors has been studied in detail in recent decades.
Climate, geography, degree of environment contamination with HEV, ecological conditions, feeding conditions, and animal welfares could be the reasons for the differences in HEV seroprevalence in sika deer in different cities.
Biological and ecological factors such as ecological needs, habitat, feeding habits have significant influences on metals bioaccumulation, bioavailability and, therefore, on their transference (Bustamante et al. 2003).
In Old World vultures the bills vary, permitting ecological separation while feeding on the same carcasses.
I'm hit and miss with the suet, and I haven't spent much time considering the myriad issues -- technical, ethical and ecological -- in feeding birds.
This gave them a wider range of ecological niches for feeding and breeding, and a means of escape from predators and from unfavorable changes in the environment.
We show that human risk preferences are exquisitely sensitive to current metabolic state, in a direction consistent with ecological models of feeding behaviour but not predicted by normative economic theory.
