The phrase "aggregation of species" is correct and usable in written English.
It can be used in contexts related to biology, ecology, or environmental science when discussing the grouping or collection of different species in a particular area or ecosystem.
Example: "The aggregation of species in this coral reef is vital for maintaining biodiversity and ecological balance."
Alternatives: "collection of species" or "assemblage of species".
Aggregation of species on the basis of their trophic relationships is a fundamental step for quantifying, visualizing and thereby uncovering the structure of food webs.
Mokany et al. (2008), in a controlled study considering 3 species, found that aggregation of species had an effect on growth rate and species resource use, although the effect was variable.
Temperature is one of the most important physical factors related to equatorial sunshine, affecting feeding, breeding and migratory behavior, as well as body thermoregulation and horizontal and vertical geographical patterns of tuna such as distribution and aggregation of species (Fonteneau 1998).
These models (see Materials and Methods) are based on the degree of spatial aggregation of species, which is a common feature in plant and animal populations [8].
The fact that we found a spatial aggregation of species observations when including the stands that might have acted as dispersal sources during the entire time period from the young stands were clear-cut, stresses the importance of the historical stand structure, also shown by Snäll et al. [61].
Aggregation of species or genus pan-genomes would be another option, removing most members of homologous sets that have consistent affinities with other lineages (e.g., ribosomal proteins).
A preliminary analysis showed aggregation of species-group outbreaks within the first 4 years of the study, which disappeared with adjustment for underlying temporal trends.
The parameter variation in both Tj and Vbias,j was continuous, with no indication of aggregations of species corresponding to distinct functional groups for crown shape or depth bias.
Finally, a differential use and aggregation of deer species around watering areas, especially during summer time, could also cause these differences between species.
Recent studies suggest that deposition of amyloid β (Aβ) into oligomeric aggregates and fibrils, hallmarks of Alzheimer's disease, may be initiated by the aggregation of Aβ species other than the well-studied 40- and 42-residue forms, Aβ40 and Aβ42, respectively.
Meanwhile, XRD and TEM results illustrate an aggregation of Pt species with increasing Pt loading on ZSM-35.
