Landscape and Urban Planning, 1995
Abstract Species richness and species diversity are classic concepts in ecology. What is new in the science of biodiversity after the Convention on Biological Diversity is: (1) that the emphasis has moved from the species to the ecosystem; (2) that the functional significance of biodiversity has been stressed.

Biodiversity and persistence of ecological communities in variable environments
Ecological Complexity, 2008Abstract Recent analyses of climate data indicate that the intensity and frequency of different weather extremes have increased. Such increased environmental variability may lead to increased species extinction rates and hence have important consequences for the long-term persistence of ecological communities.

Parasite community ecology and biodiversity
2002Abstract A wild-animal population is typically host to a whole community of parasites of different species. These parasite species may be sufficiently independent that their population dynamics can be investigated individually. In reality it would be more usual for multiple species to interact such that the presence of any one species ...

Network science in ecology: the structure of ecological communities and the biodiversity question
2012The study of networks in ecology is rapidly expanding. Although network thinking is by no means new to ecologists, cross-fertilization from other fields, ranging from computer science to sociology, has recently furthered the field significantly. Here we examine some of the applications of network science to ecology with an emphasis on its potential to ...

Nature and Culture, 2011
From time immemorial, local and indigenous communities in India have developed traditions, representations, and beliefs about the forest and biodiversity. The cultural practices and beliefs of a community play a significant role in enhancing community-based initiatives, particularly in achieving sustainability in the long term.

Science of The Total Environment, 2020
Biological communities change in response to human alteration. The response of individual taxa and the community can be used to establish preventive criteria to halt further biodiversity deterioration. Here we explore how consistent are the boundaries between Good and Moderate ecological status derived from classification systems used in North-NW Spain:

Annual Review of Ecology, Evolution, and Systematics, 2010
Today's scientists are facing the enormous challenge of predicting how climate change will affect species distributions and species assemblages. To do so, ecologists are widely using phenomenological models of species distributions that mainly rely on the concept of species niche and generally ignore species' demography, species' adaptive potential ...

Ecology Letters, 2014
AbstractEcosystems are often exposed to mixtures of chemical contaminants, but the scientific community lacks a theoretical framework to predict the effects of mixtures on biodiversity and ecosystem properties. We conducted a freshwater mesocosm experiment to examine the effects of pairwise agrochemical mixtures [fertiliser, herbicide (atrazine ...

Trends in Ecology & Evolution, 2010
The growing need for baseline data against which efforts to reduce the rate of biodiversity loss can be judged highlights the importance of long-term datasets, some of which are as old as ecology itself. We review methods of evaluating change in biodiversity at the community level using these datasets, and contrast whole-community approaches with those
