Interspecific effects of forest fragmentation on bats

Canadian Journal of Zoology, 2014
Wind-farm development may be an important contributor to forest fragmentation, but how such developments impact bats is poorly understood. We hypothesized that bat activity at a wind farm would be explained, at least in part, by attraction and avoidance behaviours caused by deforestation.

Numerical evaluation of external effects on interspecific interacting populations

International Journal of Automation and Computing, 2016
In this paper, effects of environmental and hunting parameters on the interspecific interacting populations are considered by applying the Rosenzweig-MacArthur model with the Holling type II functional response. Attenuating functions of the carrying capacity are introduced with a concern on the hunting parameters.

Linking Pollination Effectiveness and Interspecific Displacement Success in Bees

Neotropical Entomology, 2015
Pollen deposition, a surrogate for bee efficiency, becomes increasingly important during their interspecific interactions. We conducted field experiments on highly cross-pollinated melon (Cucumis melo) and watermelon (Citrullus lanatus) in order to understand how bee species with different pollination efficiencies displace each other from floral ...

The Effect of Intra- and Interspecific Competition on Coexistence in Multispecies Communities

The American Naturalist, 2016
For two competing species, intraspecific competition must exceed interspecific competition for coexistence. To generalize this well-known criterion to multiple competing species, one must take into account both the distribution of interaction strengths and community structure.

Prediction and test of the effects of interspecific competition

Nature, 1980
Although interspecific competition is of major importance in ecological and evolutionary theory1, there has been no critical study of whether indirect estimates of niche overlap accurately reflect the effects of competition on fitness as indicated by reproductive output.

Biodiversity Effects on Soil Processes Explained by Interspecific Functional Dissimilarity

Science, 2004
The loss of biodiversity can have significant impacts on ecosystem functioning, but the mechanisms involved lack empirical confirmation. Using soil microcosms, we show experimentally that functional dissimilarity among detritivorous species, not species number, drives community compositional effects on leaf litter mass loss and soil respiration, two ...

Effect of gamma radiation on interspecific incompatibility within the genusBrassica

Zeitschrift f�r Vererbungslehre, 1960
1. An attempt has been made to exploit the destructive properties of ionising radiations in overcoming the barriers to hybridisation that exist betweenBrassica oleracea, B. campestris andB. nigra. 2. One series of crosses involvingB. oleracea x B. nigra was successful only after irradiating the gametes or stylar tissues prior to crossing.

Testing for Microgeographic Effects on the Strength of Interspecific Competition

Copeia, 2018
Local adaptation to an environment can vary across very fine scales—as little as a few meters in some species, kilometers in others. This divergence at microgeographic scales has been linked to dispersal ability and could be responsible for geographic variation in the strength of species interactions.
