标题：Human population, economic activities, and wild bird conservation in Mexico: factors influencing their relationships at two different geopolitical scales
摘要：Population growth poses threats to biodiversity, specifically to sensitive species. Therefore, an understandingof the conflict between biodiversity and human population is needed to enable long-term planning of development andconservation policies by state and federal governments and society based on limitations and potentials of environments.We used a geopolitical approach to analyze data on human demography, economic activities, natural vegetation, aviandiversity, and protected areas of the 32 states of Mexico and the 30 districts of the state of Oaxaca. Using factoranalysis, we identified the biodiversity-rich geopolitical units that have a large human population and are developingintense economic activities. We then carried out a series of linear regressions between the resulting factors to testwhether they were related, suggesting areas where conservation conflicts may exist, and found that relations betweenhuman activities and natural resources vary from region to region. These results help us identify geopolitical units thatrequire detailed studies of the interactions between population and natural resources, and also highlight the importanceof using geopolitical scales as study units, where most conservation and development policies are determined, to informlocal stakeholders and decision makers.
