Context In northern Europe, changes in forest ecosystem structures are commonly attributed to the ubiquitous impact of modern forestry. However, the starting point for modern forestry was not a pristine forest, but landscapes influenced for centuries by diverse human activities.Objectives Our aims were...
Tropical forests span a huge area, harbor a wide diversity of species, and are important to water and nutrient cycling on a planet scale. But in ancient Amazonia, over 500 years ago, clearing tropical forests was a way of survival to provide land for families to farm and villages to ...
operations, fnes, and the clearing of land for agriculture) have had an impact upon these forest communities, the very limited data available from surveyor's records and other early accounts at least suggest that present-day forests are compositionally fairly similar to presettlement forests. Indeed...
Significant human impacts on tropical forests have been considered the preserve of recent societies, linked to large-scale deforestation, extensive and intensive agriculture, resource mining, livestock grazing and urban settlement. Cumulative archaeological evidence now demonstrates, however, thatHomo sapiensha...

flooding and human impact, and may introduce more noise, although these areas are spatially relatively restricted. We have further excluded areas where forests may have specific or regionally distinct adaptations to drought, fire or altitude. These include all montane and dry forests as defined by ...
Pesticides impact on human health and hazardous levels The Aral Sea area is likely a typical example of the impact of pesticide pollution on human health. UNEP (1993) related the impacts of pesticides to “the range of oncological (cancer), hematological morbidity and pulmonary dysfunction, in ad...
The rabies virus is primarily a pathogen in various carnivores inflicting heavy impact on humans and livestock throughout Latin America and elsewhere. Outbreaks from other spill-over transmissions in the last two decades include the swine acute diarrhoea syndrome originally caused by the transmission of...
However, this would not have an impact on the results during time serial trend analysis. Meanwhile, the correlation was significant (R2=0.664, P<0.001), which indicates that the model's estimation accuracy is satisfactory. Fig. 2 The validation of the Carnegie-Ames-Stanford Approach (CASA) ...
Tropical forests represent some of the most threatened land-based habitats on the planet. Credit: R. Hamilton One of the editors of the new volume, Patrick Roberts, points out that human alteration of tropical forests “probably isn’t only a recent phenomenon.” ...
