There was a significant interaction effect of habitat and size on crocodile δ13C values.
There was, however, a significant Habitat×Locations interaction: effects of habitat did not occur at all locations.
Previous studies by Pollard (1988) and Schweiger et al. (2006) observed that distribution and abundance patterns of P. aegeria differed significantly between humid and dry years and that there was an interaction effect of habitat quality.
Our findings suggest that disturbance of trophic interactions and loss of habitat modifying species interactively affect bivalve recruitment dynamics in coastal ecosystems.
It is worth stressing that our full model yielded an estimate of 0 for the variance component of the interaction between replicate and vertical position within the climate chamber [i.e., 'rack*rep(cond)'] and the interaction between the type of habitat and the conditions tested (i.e., 'type*cond') was clearly non-significant (F[6, 25.8] = 1.15, P = 0.36).
Survival differences between species in the same river system could be the result of many possible factors, including smolt physiology (e.g. overall health, sensitivity to environmental properties) and ecosystem niche (e.g. migration timing, use of habitat, interactions with competitors and predators).
The interaction of functional traits with habitat availability also significantly explained parasitoid ASRs.
Here we analysed plant pollinator networks, both including and excluding exotic species, in temperate continental forests at different spatial scales to clarify scale-variable effects of habitat area on interaction networks.
"I would personally expect climate change to have its most severe effects as a result of the interaction between habitat loss, climate change and invasive species," says Thomas.
Global rates of extinction are at an all time high and increasing because of degradation of habitat, climate change, interactions with invasive species and other human-induced impacts (Woodruff 2001).
