According to social identity theory, group members sometimes react to threats to their group's distinctiveness by asserting the distinctiveness of their group. In four studies (n = 261) we tested the hypothesis that heterosexual men with a greater propensity to be threatened by homosexuality would react to egalitarian norms by endorsing biological theories of sexuality. Heterosexual men, but no...

Biological warfare agents were one of the most feared classes of weapons that coalition troops believed Iraq might use against them. Biologic agents can either be sufficiently toxic that they kill their victims quickly, or they may induce a sufficient degree of acute disability that troops cannot fight effectively or defend themselves against an attack. The Centers for Disease Control and Preve...

−Timely detection of disease outbreak events is of paramount importance for the defense against infectious diseases and biological threats. Internet-based communications can provide good situational awareness for countries where public data collection is inadequate, unreliable or missing. The key challenge is to sift through this vast amount of unstructured text to identify relevant reports and...

Economically and politically disruptive disease outbreaks are a hallmark of the 21st century. Although pandemics are driven by human behaviours, current surveillance systems for identifying pandemic threats are largely reliant on the monitoring of disease outcomes in clinical settings. Standardized integrated biological-behavioural surveillance could, and should, be used in community settings t...

We need to understand joint ecological and evolutionary responses to climate change to predict future threats to biological diversity. The 'evolving metacommunity' framework emphasizes that interactions between ecological and evolutionary mechanisms at both local and regional scales will drive community dynamics during climate change. Theory suggests that ecological and evolutionary dynamics of...

C. Josh Donlan Department of Ecology and Evolutionary Biology, Cornell University Ithaca, New York 14853-2701 and Island Conservation University of California Long Marine Laboratories Santa Cruz, California 95060 Abstract Endangered species recovery often requires strategies that are risky, contentious, and difficult to implement. These qualities can lead to recovery actions that result from hu...

Conservation areas can be highly susceptible to alien species introductions, and therefore extra care should be taken to assess potential interactions between a biological control agent and its new environment. In the Galápagos Islands, biological control was first considered to mitigate the threats posed to flora and specialist phytophagous Lepidoptera by the invasive scale Icerya purchasi Mas...

Abstract The exposome depicts the total exposures in lifetime of an organism. Human comprises from environmental and humanistic sources. Biological, chemical, physical pose potential health threats, especially to susceptible populations. Although still its nascent stage, we are beginning recognize vast dynamic nature exposome. In this review, systematically summarize biological chemical exposom...

Medical Aspects of Chemical and Biological Warfare 2 INTRODUCTION " Gas! Gas! " This warning cry, so common in World War I, almost became real to U.S. forces again as they prepared to liberate Kuwait in late 1990. The threat of chemical, and even biological, warfare was foremost in the minds of U.S. military personnel during Operation Desert Shield, the preparation for the Persian Gulf War. Ira...
