Our study demonstrates that the ongoing paradigm shift, which recognizes that both biotic and abiotic factors shape species distributions across broad scales, can be advanced by incorporating diverse biotic factors. This information can be used to proactively create conservation/management plans to control future invasions. The predictive map of population density revealed wide-ranging potential for an invasive large mammal to expand its distribution globally. Abiotic factors, including precipitation and potential evapotranspiration, were also important predictors. Incorporating diverse biotic factors, including agriculture, vegetation cover, and large carnivore richness, into species distribution modeling substantially improved model fit and predictions. Using generalized linear models and model selection techniques, we used 129 estimates of population density of wild pigs (Sus scrofa) from 5 continents to evaluate the relative importance, magnitude, and direction of biotic and abiotic factors in predicting population density of an invasive large mammal with a global distribution. In particular, biotic factors, such as predation and vegetation, including those resulting from anthropogenic land-use change, are underrepresented in species distribution modeling, but could improve model predictions. However, the relative importance of biotic and abiotic factors in predicting species distributions is unclear. Immigrants "born abroad as a foreign national" may still beįoreigners at the time of the census or may have become French.Biotic and abiotic factors are increasingly acknowledged to synergistically shape broad-scale species distributions. Information on current nationality and nationality at birth.įoreigners and immigrants form two different categories. Or foreign and, among French citizens, those who were born FrenchĪnd those who have been naturalized. ![]() Inhabitants are distinguished by their nationality, i.e. With French nationality and immigrants, who are born with a Inhabitants, a distinction is generally made between persons born Of inhabitants who were born outside France. Population censuses provide an opportunity to count the number With its research units, the Institute promotes communication and exchange within the scientific community and between researchers and the general public while conducting numerous European and international research projects. INED’s approach to demography is resolutely open and interdisciplinary, implicating a wide range of disciplines including economics, history, geography, sociology, anthropology, biology and epidemiology. The Institute’s missions are to study the populations of France and other countries, to ensure wide dissemination of the knowledge thereby acquired, and to provide training in research through research. INED was founded in 1945, and in 1986 it acquired the status of an Etablissement Public à Caractère Scientifique et Technologique (EPST), meaning that it is under joint administrative supervision of the "Ministère de l’enseignement supérieur et de la recherche", of the "Ministère de la santé et de la prévention et du Ministère des solidarités, de l’autonomie et des personnes handicapées". ![]()
