Ecology is defined as the science that studies relationships between organisms and their environments. There are many different perspectives through which these relationships can be viewed. As a natural science, ecology focuses on understanding the physical, chemical and biological interactions that take ...
Ecotourism is a combination of ecology (the study of systems of living things) and tourism. It is defined as “responsible travel to natural areas that preserves the environment and improves the welfare of the local people” by the International Ecotourism Society. Actually, ecotourism can mean tr...

This contribution proposes the meta-ecosystem concept as a natural extension of the metapopulation and metacommunity concepts. A meta-ecosystem is defined as a set of ecosystems connected by spatial flows of energy, materials and organisms across ecosystem boundaries. This concept provides a powerful th...

The gene pool (total aggregate of genes in a population at a certain time) is affected as organisms with phenotypes that are compatible with the environment are more likely to survive for longer periods, during which time they can reproduce more often and pass on more of their genes. The ...
