A multivariate analysis method based on the Fuzzy Set Theory was used to perform quantitative analyses to find clusters of plants. The Graph Theory was instead applied in order to detect trajectories and similarity gradients in the system of groups of species. The results confirmed that groups of...
A keystone species is a species that is particularly important in an ecosystem, and their importance is out of proportion to how many other species there are in the ecosystem. Some examples of keystone species include bison, prairie dog, and otter. These are keystone species because they ...
Examples of keystone species are Pisaster (P), sea otters (O), predatory whelks (Concholepas, C), and freshwater bass (B). Dominants are high proportional biomass species whose large effects are not disproportional to their biomass, such as trees (T), giant kelp (K), prairie grasses (G...

Other Keystone Species There are a number of other well-described examples where keystone species act as determinate predators. Sea otters (i) regulate sea urchin populations, which in turn feed upon kelp and other macroalgae (Duggins 1980). The otters keep the sea urchin populations in check, ...
Explore the kelp forest food web. Study the kelp forest ecosystem, including some of the threats it faces, and see examples of kelp forest plants and animals. Related to this Question Are otters a keystone species? Why are sea otters a keystone species?
portion of food crops annually, there are many more beneficial fungi that promote tree and shrub growth by helping plants draw in water, scavenge nutrients from the soil, aid in stress tolerance and repel pathogens; indeed, almost all plant species have symbiotic relationships with fungi [13,14...
differentiation has also been observed in other plants, such asDysosma versipellis,Cephalotaxus oliveriandLiriodendron chinense[66,67,68]. Similar genetic patterns from different species indicated that topography and environmental heterogeneity could be the main drivers for intra-species differentiation in ...
keystone species theory remains a young theory and the underlying concepts are still being developed. For instance, the term was originally applied to a predator species (Pisaster ochraceous), but now the term 'keystone' has been extended to include prey species, plants, and even habitat ...
