Ecology 91— The study of mammals has promoted the development and testing of many ideas in contemporary ecology. Romero, M. Descuentos y travesuras. Polygon indicates the main area of the whaling operations. Ecological System Analysis, Pullman, Washington.

The study of mammals has promoted the development and testing of many ideas in contemporary ecology. Here we address recent developments in foraging and habitat selection, source—sink dynamics, competition both within and between speciespopulation cycles, predation including apparent competitionmutualism, and biological invasions. Because mammals are appealing to the public, ecological insight gleaned from the study of mammals has disproportionate potential in educating the public about ecological principles and their application to uae management.

Mammals have been central to many computational and statistical developments in recent ie, including refinements to traditional approaches and metrics e. The study of mammals also poses challenges in terms of fully characterizing dynamics in natural conditions. Ongoing climate change threatens to affect global ecosystems, and mammals provide visible and charismatic subjects for research on local and regional effects of such change as well as predictive modeling of the long-term effects on ecosystem function and stability.

Although much remains to be done, the population ecology of mammals thf to be a vibrant and rapidly developing field. We anticipate that the next quarter century will prove as ks and productive for the study of mammals as has the recent one. Oxford University Press is a department of the University of Oxford.

Moreover, reproductive success has been linked to climate conditions through a negative effect on foraging-ground quality; and accordingly, in view of the current global-warming projections, the level of recovery of the SRW population from the southwestern Atlantic Ocean would be compromised in overcoming years of low recruitment through changes in prey distribution and abundance driven by climate Google Scholar TM Check.
