摘要

本研究报告了巴西卡廷加一条雌性蟒蛇与五只雄性蟒蛇的生殖聚集。这一观察结果强化了一妻多夫制的证据，即体型较大的雌性与不同的雄性交配。我们的记录突出了性别大小二态性对聚集体形成的影响。

Hard Mating Aggregation as Evidence of Polyandry in the Red-Tailed Boa, Boa constrictor (Squamata: Boidae), in a Brazilian Caatinga Population

This study reports a reproductive aggregation of a female Boa constrictor with five males in the Brazilian Caatinga. The observation reinforces the evidence of a polyandrous system, favoring larger females that copulate with different males. Our record highlights the influence of sexual size dimorphism in the formation of aggregations.

期刊介绍： Ecology and Evolution is the peer reviewed journal for rapid dissemination of research in all areas of ecology, evolution and conservation science. The journal gives priority to quality research reports, theoretical or empirical, that develop our understanding of organisms and their diversity, interactions between them, and the natural environment. Ecology and Evolution gives prompt and equal consideration to papers reporting theoretical, experimental, applied and descriptive work in terrestrial and aquatic environments. The journal will consider submissions across taxa in areas including but not limited to micro and macro ecological and evolutionary processes, characteristics of and interactions between individuals, populations, communities and the environment, physiological responses to environmental change, population genetics and phylogenetics, relatedness and kin selection, life histories, systematics and taxonomy, conservation genetics, extinction, speciation, adaption, behaviour, biodiversity, species abundance, macroecology, population and ecosystem dynamics, and conservation policy.
