PRAIRIE DOG DECLINE REDUCES THE SUPPLY OF ECOSYSTEM SERVICES AND LEADS TO DESERTIFICATION OF SEMIARID GRASSLANDS.

Prairie dog decline reduces the supply of ecosystem services and leads to desertification of semiarid grasslands.

Anthropogenic impacts on North American grasslands, a highly endangered ecosystem, have led read more to declines of prairie dogs, a keystone species, over 98% of their historical range.While impacts of this loss on maintenance of grassland biodiversity have been widely documented, much less is known about the consequences on the supply of ecosyste

An N-terminally truncated envelope protein encoded by a human endogenous retrovirus W locus on chromosome Xq22.3

Abstract Background We previously showed that the envelope (env) sequence of a human endogenous retrovirus (HERV)-W locus on chromosome Xq22.3 is transcribed in human cent dyyni peripheral blood mononuclear cells.The env open reading frame (ORF) of this locus is interrupted by a premature stop at codon 39, but otherwise harbors a long ORF for an N-

Use of biotechnology in two bamboo species propagation

Physical qualities, low cost and availability of bamboo trees make the material ideal for building houses, furniture, decorative and utilitarian crafts.The development of new plantations is neeed for the sustainable use of bamboos.The in vitro propagation is an effective way.This work shows the main results in the in vitro propagation of two bamboo
