WhyWhere is a new ecological niche modeling (ENM) algorithm for mapping and explaining the distribution of species. The algorithm uses image processing methods to efficiently sift through large amounts of data to find the few variables that best predict species occurrence. The purpose of this paper is to describe and justify the main parameterizations and to show preliminary success at rapidly ...

[1] The globally-averaged atmospheric methane abundance determined from an extensive network of surface air sampling sites was constant at 1751 ppb from 1999 through 2002. Assuming that the methane lifetime has been constant, this implies that during this 4-year period the global methane budget has been at steady state. We also observed a significant decrease in the difference between northern ...

A crossdated, replicated, chronology of 114 years (1901-2014) was developed from internal growth increments in the shells of Glycymeris glycymeris samples collected monthly from the Bay of Brest, France. Bivalve sampling was undertaken between 2014 and 2015 using a dredge. In total 401 live specimens and 243 articulated paired valves from dead specimens were collected, of which 38 individuals w...

D irective 2008/50 CE of the European Parliament and Council of 21 May 2008 on ambient air quality and cleaner air for Europe was recently approved. 1 Annex XIV of the Directive establishes two stages for particulate matter having a diameter of under 2.5 micron (PM 2.5). Stage 1 indicates that the calendar year limit value for this pollutant is to be 25 mg/m 3 and that the date by which the lim...

With the intensification of climate change, understanding impacts change on water cycle is vital for integrated watershed management. Based precipitation and temperature data from 1980 to 2018, climatic characteristics Three Gorges Reservoir Area were analyzed. The Soil Water Assessment Tool (SWAT) was used simulate spatial temporal distribution runoff quality. result indicated that showed clea...
