在卵生动物中,巢捕食是影响卵生动物繁殖失败的重要因素之一,巢捕食不仅影响种群的密度,也能改变种群的年龄结构。巢捕食反应了天敌对该物种的选择压力,清楚地了解捕食风险、捕食率及其影响因素对于研究其种群变化、繁殖特征,以及保护对策的提出具有极其重要的意义。
确定外来物种在入侵区的气候生态位漂移及其决定因素是准确预测外来种入侵风险的关键,基于最新发展的外来种气候生态位漂移量化框架,最近的研究发现外来鸟类和外来植物在入侵区都很少发生气候生态位的漂移,然而,这一规律尚未在其它生物类群中得到印证,也不清楚什么因素会影响外来种在入侵区的气候生态位漂移。
1.Variation in the degree of sexual size dimorphism (SSD) is a widespread phenomenon and is commonly attributed to variation in sex-specific patterns of selection.
We studied for the first time the occurrence of multiple paternity,female reproductive success,and neonate fitness in a terrestrial elapid snake,the Chinese cobra (Naja atra),population using 9 micros

The vulnerable Chinese cobra (Naja atra) has a distribution ranging from the south of the Yangtze River to northern Vietnam and Laos,within which large mountain ranges and water bodies may influence t

The expensive-tissue hypothesis states that an increase in the size of a metabolically expensive tissue is offset by a decrease in the size of other metabolically expensive tissues.
