The harvest of non-timber forest products (NTFPs), together with other sources of anthropogenic disturbance, impact plant populations greatly. Despite this, conservation research on NTFPs typically focuses on harvest alone, ignoring possible confounding effects of other anthropogenic and ecological factors. Disentangling anthropogenic disturbances is critical in regions such as India's Western ...

Mercury (Hg) is a naturally occurring element that poses considerable health risks to humans, primarily through the consumption of fish which have accumulated harmful levels of mercury in their tissue. This bioaccumulation of mercury in fish is a result of elevated exposure from a number of sources including industrial emissions, atmospheric deposition, and mercury-bearing products such as ther...

The effects of different anthropic activities (vineyard: phytosanitary protection; winery: pressing and sulfiting) on the fungal populations of grape berries were studied. The global diversity of fungal populations (moulds and yeasts) was performed by pyrosequencing. The anthropic activities studied modified fungal diversity. Thus, a decrease in biodiversity was measured for three successive vi...

Their biomass production and CO2 sequestration equals that of all terrestrial plants taken together. Phytoplankton productivity is controlled by...

A comparison of observations with simulations of a coupled ocean-atmosphere general circulation model shows that both natural and anthropogenic factors have contributed significantly to 20th century temperature changes. The model successfully simulates global mean and large-scale land temperature variations, indicating that the climate response on these scales is strongly influenced by external...

Mass mortalities due to disease outbreaks have recently affected major taxa in the oceans. For closely monitored groups like corals and marine mammals, reports of the frequency of epidemics and the number of new diseases have increased recently. A dramatic global increase in the severity of coral bleaching in 1997-98 is coincident with high El Niño temperatures. Such climate-mediated, physiolog...

The offered approach is based on the establishment of the functional dependence between river water discharge (Q) and suspended ms ,in a number of observations, which noticeably differs from the mean value (R) of subsequent allocated period(s). The earliest period anthropogenic component during the subsequent period(s) is the difference between an actual suspended sediment yield and its hypothe...

Abstract Particulate black carbon (BC) affects global warming by absorbing the solar radiation, affecting cloud formation, and decreasing ground albedo when deposited to snow or ice. BC has also a wide variety of adverse effects on human population health. In this article we reviewed emission factors (EFs) major anthropogenic sources, i.e. traffic (incl. marine aviation), residential combustion...
