Interspecific competition influences fitness benefits of assortative mating for territorial aggression in Eastern Bluebirds (Sialia sialis).
Many of these studies confirm Connell's idea (Connell 1975) that the threat of predation usually trumps the disadvantages of increased interspecific competition in mediating habitat selection and resource use (Heithaus et al.
The results reveal a cognitive mechanism by which largebrained primates can buffer the effects of seasonal declines in food availability and increased interspecific competition to facilitate first access to nutritious food.
Data indicated that the interspecific competition of wild mustard significantly reduced wheat grain yield.
Interspecific competition and resource partitioning have been well documented for fish species in freshwater systems (Persson et al.
She said that bipedal jerboas and quadrupedal jirds share the same habitat, predators, food source, and active hours and it appears that their different forms of locomotion create differing predator evasion abilities, allowing jerboas to forage further from their burrows, thus limiting interspecific competition.
Although both algal species inhabit a similar niche and have a high potential for interspecific competition for resources, these algae have never been found growing in monospecific stands in Kassari Bay (Martin et al.
Notonectids combined with hydrometrids yielded a higher larvae and pupae consumption rates suggesting that there is an interspecific competition on the prey population.
elegans the density of another shrimp, Palaemon adspersus Rathke, has drastically declined, which may point to the potential of strong interspecific competition between them (Grabowski, 2006).
The models key parameters are intraspecific and interspecific competition coefficients and although it assumes per capita growth rates are linear, decreasing functions of the densities of each of the species, nonlinear versions are easily constructed (Chesson, 2000).
Such patterns of niche complementarity imply adaptive responses to interspecific competition, either past or present.
