If it is generally true that closely related, non-sibling, ecologically distinct animal species are often permeable to introgression, the nature of such species, their ecology, causes of speciation [ 1, 16], phylogeny reconstruction [ 43], as well as conservation issues concerning hybridizing populations [ 44] all require re-evaluation.
Dr. Jones suggested that Aboriginal "firestick farming," the burning the brush for food, fatally changed the ecology, causing the sudden death of Australia's megafauna, marsupials and reptiles whose remains are common but whose fate is mysterious.
Our findings suggest an Arctic effect on viral ecology, caused perhaps by low ecosystem productivity and low host densities relative to available water.
As in the past 3 EID zoonoses theme issues, we have called for renewed effort for the public health and animal sectors to work together, in this case to mitigate the impact on infectious disease ecology caused by unrestricted translocation of animals.
As an apex predator (like wolves and lions ), their loss would weaken the ocean ecology and cause an imbalance on many other species.
Population ecology asks what causes abundances to fluctuate.
Wind engineering in Africa can assist in collecting data on wind climate, developing wind energy, reducing the adverse effects of wind and related drifting sand in building activities and agriculture, and limiting other wind-related disasters, in environment and ecology, such as those caused by erosion and fire.
The goals of plant ecology are to understand the causes of their distribution patterns, productivity, environmental impact, evolution, and responses to environmental change.
It is putting stress on the ecology of the region and causing rapid erosion of shorelines that are now exposed to more vigorous waves.
These levees have altered hydrology and ecology and are a primary cause of massive wetland loss in the delta.
New approaches included work on metapopulation networks, "metacommunities" and regional trophic webs, large-scale distribution patterns of species, and the long-term development of landscapes, often pursued in the cause of conservation ecology (Likens 1989; Delcourt and Delcourt 1991; Gilpin and Hanski 1991; Brown 1995; Gaston and Blackburn 2000; Polis et al. 2004; Holyoak et al. 2005).
