List of Coastal Oregon and Washington freshwater fish taxa, their sister taxa, estimated age of break, and whether secondary
sympatry has been established.
2017: Spatio-temporal interactions facilitate large carnivore
sympatry across a resource gradient.
Much remains unknown about weta biology, particularly with regard to species coexistence and production of hybrids where these weta meet in
sympatry lends an extra layer of complexity to the situation.
at regional scale) and at a local scale where at least two such species coexist in
sympatry. We test the hypothesis whether populations of C.
gaimardi that occur on the southeast Brazilian coast, both in
sympatry and allopatry.
guariba clamitans in Sao Vicente do Sul, Rio Grande do Sul, Brazil, which extends the southern boundary of
sympatry between these species and, possibly, the limit of the hybrid zone.
Burford (2009) concluded that the 2 lineages speciated allopatrically much earlier than the LGM and that they have subsequently expanded ranges to form an area of
sympatry from central Oregon to northern California.
In fact, diversity in
sympatry rather than the existence of only one taxon/site appears to be the rule rather than the exception in the S.
In the study of VILLA (1977), the artificially inoculated drosophilidflie larvae, success fully infested egg-masses of Agalychnis callidryas, Hylaebraccafa (=Dendrosphusebraccafus), Cenfrolenella fleischmanni (=Hyalino bafhrachium fleischmanni) and Cenfrolenella pulverafa (=Terafohyla pulverafa), but not those of Cenfrolenella granulosa (=Cochranella granulosa); all these species were in
sympatry in San Jose de la Montana, Nicaragua.
Overall, the niche breadth for both species in
sympatry indicates that the jaguar is a more specialised predator than puma, which exhibits more generalist patterns (Emmons 1987, Taber et al.
Are there such areas in northern Pakistan that constitute an environmental transition zone, where both taxa can occur in
sympatry. Unfortunately, a large area of up to 50,000 km 2 in northwestern Pakistan, next to the currently known range limits of and between both water snake species, exhibit plenty of suitable habitats but lack any vouchered species identification to this day.
In most areas, this species occurs in
sympatry with the introduced Gambusia holbrooki Girard, 1859.
