three simplified scenarios are conceivable for the rarer species. Relative to abundant species, rare species may, on average, (1) decline proportionally, (2) decline less or
3D) may be explained by the fact that both mycorrhizal types could be found in angiosperms or gymnosperms, and that SRL values of angiosperms overlap with gymnosperms values61. The influence of some plant functional types on SOC stability supports the idea that species with nutrient-rich litters...
The specificity of rhizobia-legume associations means that underused legume species may depend on seed inoculation with their rhizobial partners. For black medic (Medicago lupulina) and lucerne (Medicago sativa) little is known about the natural prevalence of their rhizobial partner Ensifer meliloti in...
A.man may use instruments to transport fishB.the movement of fish doesn't depend on human instrumentsC.it is because of man that fish can move from one river to anotherD.it is through man's tools that fish can move from one river to another(4)Which of the following best states the ...
The other species would likely need to be in the same taxonomic group (Outhwaite et al., 2019) but may or may not be considered to have been observed by the same observer (van Strien et al., 2010). Critically, each non-detection for each species must be assessed for each time ...
is a different story, because our hope of surviving a mass extinction is rather low. Humans are at the top of food pyramid, which means we consume large quantities of food and other resources. We are extremely fragile because our existence depends more on other species than they depend on ...
Species differences in seedling survival in deeply shaded understories (i.e., shade tolerance) may depend on both seed size and growth rates, but their rel... WPB Reich - 《Ecology》 被引量: 719发表: 2000年 Effects of seeds size and growth form on seedling establishment of six monocarpic...
other species may regularly dwell on multiple resources ranging from vertebrate dung to rotting plant matter (Pont & Meier,2002). In Europe several (up to 12) widespread species of the genusSepsiswith very similar ecological niches coexist in and around livestock faeces, often on the same pasture...
Increasing climatic variability may therefore cause greater physiological stress to ectotherms compared to endotherms with likely severe consequences for their spatial distribution21,22. The influence of climate variability on species might also depend on the geographic regions in which they occur. In the...
It has traditionally been thought that reproductive and fertility outcomes mainly depend on the female factor1,2. The role of the male gamete has been limited to the narrow window of fertilization and the sperm cell considered almost like a simple vehicle for male DNA delivery to the embryo3,...
