“Ecologically and evolutionarily relevant NPP” [“eNPP”:35,36], essentially NPP during the growing season, peaks around 60 degrees north and south for terrestrial and marine ecosystems, and is thought to drive parallel geographical peaks in body size for a range of mammals including humans34,...
research, biological study, analytical work, etc. Thus, any grouping of individuals based on some significant characteristic“common feature”for the matter of statistical analysis comprises a population. It is from this population that a sample is drawn. The sample thereby ...
andnis the time interval between these two time periods. Next, we calculated the population and GDP per-capita rates (% annual) at the city scale using the Oxford Economics database. After combining the datasets on these three variables, our sample size was reduced to 363 cities. We assumed...

However, this eliminates certain classes of people from the possibility of being selected for the sample: poor people with no phones; people who use cell phones and thus don't appear in the phone book; people with unlisted numbers; and most college students. Gathering population data for ...
Invasive species are not only a major threat for native biodiversity (such as species decline or extinction) and ecosystems [1,2], but also cause considerable annual damage to agriculture, property, human health and safety, and natural resources [3,4]. It is vital to understand the dynamics ...
Population models are increasingly being considered as a tool for pesticide risk assessment in order to evaluate how potential effects act on the population level and population recovery. While the importance and difficulties of such models have been dis
Parasitic nematodes are highly diverse and common, infecting virtually all animal species, and the importance of their roles in natural ecosystems is increasingly becoming apparent. How genes flow within and among populations of these parasites - their p

Air pollution remains as a substantial health problem, particularly regarding the combined health risks arising from simultaneous exposure to multiple air pollutants. However, understanding these combined exposure events over long periods has been hinder
