Ecology: Compensating for Extinction
نویسنده
چکیده
Food web interactions allow communities to compensate for the loss of species. Compensation of this kind may reshuffle communities so that today's resilient species are tomorrow's vulnerable species, creating a false impression of ecosystem stability following the first wave of extinction.

متن کاملCommentary on Holmes et al. (2007): resolving the debate on when extinction risk is predictable.
We reconcile the findings of Holmes et al. (Ecology Letters, 10, 2007, 1182) that 95% confidence intervals for quasi-extinction risk were narrow for many vertebrates of conservation concern, with previous theory predicting wide confidence intervals. We extend previous theory, concerning the precision of quasi-extinction estimates as a function of population dynamic parameters, prediction interv...
متن کاملExtinction times in experimental populations.
Predicting population extinctions is a key element of quantitative conservation biology and population ecology. Although stochastic population theories have long been used to obtain theoretical distributions of population extinction times, model-based predictions have rarely been tested. Here I report results from a quantitative analysis of extinction time in 281 experimental populations of wat...
متن کاملA review of extinction in experimental populations.
1. Population extinction is a fundamental ecological process. Recent experimental work has begun to test the large body of theory that predicts how demographic, genetic and environmental factors influence extinction risk. We review empirical studies of extinction conducted under controlled laboratory conditions. Our synthesis highlights four findings. First, extinction theory largely considers ...
متن کاملInterplay between changing climate and species' ecology drives macroevolutionary dynamics.
Ecological change provokes speciation and extinction, but our knowledge of the interplay among the biotic and abiotic drivers of macroevolution remains limited. Using the unparalleled fossil record of Cenozoic macroperforate planktonic foraminifera, we demonstrate that macroevolutionary dynamics depend on the interaction between species' ecology and the changing climate. This interplay drives d...
