Relative abundance refers to the abundance of a species compared to other species in a given ecosystem. Note that this is not necessarily a statement... Learn more about this topic: Population Dynamics in Ecology: Definition & Concepts
The theory of island biogeography1 asserts that an island or a local community approaches an equilibrium species richness as a result of the interplay between the immigration of species from the much larger metacommunity source area and local extinction

The species composition, abundance and distribution of sea cucumbers in the intertidal zone of East Cab-ilan Island, Province of Dinagat Islands, Philippines were assessed using a transect-quadrat method. Sampling was done once at the two identified sampling stations in three replicates. A total of...
Using the 16S rDNA-containing clones as a proxy, the relative abundance of different archaeal groups appeared to vary depending on the libraries (Figure 1). Although Group I Crenarchaeota are thought to constitute the majority of the archaeal fraction in deep waters (Karner et al., 2001; ...
The grass carp is one of the most important herbivore consumers in aquatic ecosystems and plays key roles in controlling macrophyte abundance. To assess the trophic role of grass carp and their potential grazing pressure on macrophytes in their native range, we quantified their...

characterizing the plant–herbivore interface at the bottom of the food webs is an important factor affecting whole ecosystems, including animal abundance, fauna size, plant damage levels, competitiveness among herbivorous species, determination of hostplant, invasiveness, and the evolution of animal trait...
