Impacts of parasitic plants on natural communities

Tansley review Impacts of parasitic plants on natural communities

Parasitic plants have profound effects on the ecosystems in which they occur. They are represented by some 4000 species and can be found in most major biomes. They acquire some or all of their water, carbon and nutrients via the vascular tissue of the host’s roots or shoots. Parasitism has major impacts on host growth, allometry and reproduction, which lead to changes in competitive balances be...

Impacts of Fire-Suppression Activities on Natural Communities

The ecological impacts of wildland fire-suppression activities can be significant and may surpass the impacts of the fire itself. A recent paradigm shift from fire control to fire management has resulted in increased attention to minimizing the negative effects of suppression. While the philosophy behind minimumimpact suppression tactics has provided a good first step in this direction, increas...

Natural and human impacts on invertebrate communities in Brazilian caves.

Species richness, abundance, distribution and similarity between cave invertebrate communities were compared among seven caves located in the Peruaçu River valley, north of Minas Gerais State, Brazil. Such comparisons aimed to determinate the degree of biological complexity in the sampled caves, calculated by the "Index of Biological Complexity in Caves", presented in this manuscript. The prese...
