Recent research has reported an association between facial width‐to‐height ratio (fWHR) and both fighting performance and judgments of formidability in a sample of mixed martial arts (MMA) combatants. The results provide evidence of fWHR being associated with sporting performance and aggression in men. However, it has been argued that the effect of fWHRmight be a by‐ product of associations bet...

Epidemiological studies report an association between exposure to biomass smoke and cardiopulmonary morbidity. The mechanisms for this association are unclear. The aim of the present study was to characterise the acute pulmonary and systemic inflammatory effects of exposure to forest fire smoke. Seasonal forest firefighters (n = 52) were recruited before and/or after a day of fire-fighting. Exp...
Introduction: The fire fighting is one of the demanding and hazardous of all occupations so that it is recorded 96% deaths occurred in firefighters who were over 40 years old. Reported high activity of the sympathetic system and heart rates in excess of 95% HR during simulated or live firefighting tasks. The purpose of this study was determining the effect of ageing and overweight on biological...
The Muslim Brotherhood, as one of the oldest political-religious parties in the Middle East, has been able to make eye-catching political achievements in a number of countries such as Turkey and Egypt in the past two decades. As the birthplace of this political party, Egypt, with the removal of military dictatorship in 2010, turned into a base for the Muslim Brotherhood to wield power after 84 ...
OBJECTIVE Group fighting is portrayed as a piece of Americana among delinquent youth, but the behavior produces significant multifaceted negative consequences. The current study examines the heterogeneity and correlates of group fighting using national-level data. METHOD Employing data from the National Survey on Drug Use and Health between 2002 and 2013 (n = 216,852), we examine links betwee...
Selection against hybridization can cause mating traits to diverge between species in sympatry via reproductive character displacement (RCD). Additionally, selection against interspecific fighting can cause aggressive traits to diverge between sympatric species via agonistic character displacement (ACD). By directly affecting conspecific recognition traits, RCD and ACD between species can also ...
In many animal taxa, prior contest experience affects future performance such that winning increases the chances of winning in the future (winner effect) and losing increases the chances of losing in the future (loser effect). It is, however, not clear whether this pattern typically arises from experience effects on actual or perceived fighting ability (or both). In this study, we looked at win...
The male Siamese fighting fish, Betta splendens, builds a bubble nest on the water surface to care for offspring during the reproductive period. To our knowledge, this study is the first to determine the composition of the bubble nest and to compare the pharyngeal organs of male and female Siamese fighting fish to determine the relationship between the pharyngeal organ and the ability to make b...
