Activity budgets influence the expression of life history traits as well as population dynamics. For ectotherms, a major constraint on activity is environmental temperature. Nonetheless, we currently lack a comprehensive conceptual framework for understanding thermal constraints on activity, which hinders our ability to rigorously apply activity data to answer ecological and evolutionary questi...

Models of coextinction identify parasites as one of the most menaced ecological groups. The number of host species a parasite uses should strongly affect its risk of coextinction. The naïve expectation is that the lower the number, the higher is the parasite's risk of being left with no hosts. Here we analyse the coextinction risk of 12,141 fish parasite species and find that highly specific pa...

In response to climate change, many nations are facing a crisis in regards to managing land use, mitigating environmental degradation, and otherwise pursuing sustainable development. Vietnam faces many unique circumstances, both historical and present, that make it an interesting case study in such topics. As the discernable impacts of climate change increase, it is necessary for Vietnam to pur...

Prevention researchers have found that drinking in different contexts is related to different alcohol problems. Where and with whom people drink affects the types of alcohol-related problems they experience. Consequently, identifying those contexts that result in the greatest number of problems provides a novel opportunity to target new prevention efforts aimed at those contexts. However, ident...

example, should they first address a vulnerability with a severity of “5” or one with a severity of “high”? The Common Vulnerability Scoring System (CVSS) is a public initiative designed to address this issue by presenting a framework for assessing and quantifying the impact of software vulnerabilities. Organizations currently generating CVSS scores include Cisco, US National Institute of Stand...

Fishing has become a major conservation threat to marine fishes. Effective conservation of threatened species requires timely identification of vulnerable species. However, evaluation of extinction risk using conventional methods is difficult for the majority of fish species because the population data normally required by such methods are unavailable. This paper presents a fuzzy expert system ...

OBJECTIVES How to provide effective and efficient care to the burgeoning and aging populations of the major cities of low- and middle-income countries constitutes one of the principle public health issues of our times. We evaluated the Family Health Strategy, the Brazilian national health system's public approach to primary health care, in the major city of Belo Horizonte, describing trends and...
