Abstract Organic anion-transporting polypeptides (OATPs) are integral membrane transporters that mediate cellular uptake of a broad range of substrates in humans. The functions of OATPs in insects are less well investigated and only poorly understood. A large number of compounds potentially toxic to insects are organic anions that include secondary plant an...
A root rot caused by a Heterobasidion species of fungi is widespread in coniferous forests of California and can cause a huge amount of growth loss and death of infected trees. Applications of the borax containing pesticides Sporax and Cellu-Treat to recently cut stumps can be highly effective at preventing the spread of this fungus....

Abstract Background Assessing cumulative effects of anthropogenic and natural disturbances on forest carbon (C) stocks and fluxes, because of their relevance to climate change, is a requirement of environmental impact assessments (EIAs) in Canada. However, tools have not been developed specifically for these purposes, and in particul...
<p>In a ponderosa pine (Pinus ponderosa Laws.) forest near Flagstaff, AZ, USA, there was a striking pattern in forest characteristics, consisting of substands of old-growth trees (28–120 cm diameter at breast height (dbh) and 200–500 years old) and of saplings (1.5–10 cm dbh and 60–70 years old) in a matrix of pole-sized trees (10–28 cm dbh and 60–100 years old). Tree si...
Plants have long been cultivated to improve quality of life in dense human settlements, mitigating the environmental stresses of urban living. Urban landscape elements include gardens, trees and lawns designed to provide aesthetic and functional benefits to local residents, as well as urban natural areas that reflect the native biome vegetation. Different types of informal green space are typicall...
