Channel Islands slender salamanders are broadly
sympatric with black - bellied slender salamanders (B. nigriventris) on Santa Cruz Island, where both species tend to occupy similar habitats (Campbell, 1931b; Schoenherr et al., 1999).
A population refered to B. nigriventris is
sympatric with this species on Santa Cruz Island.

The Jehol birds faced competition
with pterosaurs, and occupied
sympatric habitats
with nonavian theropods, some of which consumed birds.
The East African cichlid fishes of Lake Malawi are ideal for investigating behavioral adaptation to environment, as within genera, fine - scale niche partitioning has resulted in

A recent study found that genetic differentiation was much lower throughout a large fraction of the genome between the now
sympatric species pair Helianthus annuus and H. petiolaris, which have diverged for ∼ 1.0 million years, than between more closely related species
with non-overlapping geographical ranges [34], [35].
Thus, frequent interaction
with humans and reduced predation are likely the most important factors that distinguish the study population from
sympatric commensal house mouse populations [16].
