Broader niches resulted in increasing niche overlap and competition but enhanced species mobility, allowing abundance levels to approach expected values determined by map resources.
The results for both measures range from 0 (no niche overlap) to 1 (identical niches).
In addition, redundancy (niche overlap between species) and modularity (the interconnectedness of a system's components) are considered to be important factors that determine an ecosystem's resilience.
The degree of trophic niche overlap was 0.69.
Niche overlap was highest during the dry season, lowest at the core-area scale, and increased with spatial resolution.
Data were analyzed with the partial triadic analysis (PTA) and correlograms, while niche overlap was computed with the Pianka index.
Finally, we found a negative relationship between niche overlap and specificity, with more specialised phages tending to exhibit lower overlap (Figure 4).
We show that the co-occurrence of species on a continuum of specialism/generalism is influenced by niche overlap, phage impact on bacterial hosts, and host phylogenetic structure.
We saw that niche overlap was relatively insensitive to specificity at low levels of the latter and strongly decreased for sufficiently high levels of specificity.
Niche overlap between two phages denoted by a and b is given by C ab = 1 - 1 2 ∑ Ω ai - Ω bi, (4).
In addition, we compared the models in terms of niche overlap and the landscape metrics computed from the predicted distribution maps.
