We present the diversity of Asteraceae in Arequipa Region southern Peru, an area strongly influenced by volcanism, which has given rise to different soil types and determined a very wide bioclimatic vegetational zonation. distribution endemisms Peru Arequipa, dry puna. For this purpose, we have used methodology Rivas-Martínez, characteristic soils each collection point, distance localities from...

Although not well known, Arctic grayling can move through saline waters and are captured regularly in nearshore coastal waters in Arctic Canada and Alaska with salinities up to 18 ppt. We highlight the implications this has for Blair et al. (2016), a paper recently published in Conservation Physiology.

Abstract Laboratory scale experiments and numerical modelling were employed in this study to investigate saltwater intrusion fractured aquifers. Saline was initiated one homogeneous six experimental aquifers containing individual discontinuities of varying length orientation. Automated image processing enabled high precision quantification three variables, the toe saline wedge, width mixing zon...
