摘要

群体中个体之间的争斗可能由多种因素引起，比如对食物、住所和性伴侣的争夺。本研究旨在评价亚马逊河对虾(Macrobrachium amazonicum)的伤害发生模式。2012年2月至2013年9月，对巴西圣保罗河Tietê河对虾及其环境因子进行逐月采样。将个体划分为8个不同的人口统计学类别，并对身体损伤进行宏观分析，将其分为4类(0-4)。在收集的2234只对虾中，124只出现了一种或多种物理损伤。占统治地位的种姓的男性受到的伤害最多，这表明这些群体更频繁地卷入纠纷。繁殖事件可能是淡水对虾发生打斗的强烈刺激因素，因为在繁殖高峰期间观察到的伤害最多。

Body injuries in male morphotypes of the Amazon River prawn (Macrobrachium amazonicum)

ABSTRACT Fights between individuals in a population can be motivated by several factors, such as disputes over food, shelter and sexual partners. The present study aimed to evaluate the pattern of injury occurrence in the Amazon River prawn (Macrobrachium amazonicum). Prawns and environmental factors were sampled monthly, from February 2012 to September 2013, in the Tietê River, São Paulo, Brazil. Individuals were classified into eight different demographic classes and analyzed macroscopically for body injuries, which were separated into four categories (0–4). From the 2,234 prawns collected, 124 presented one or more types of physical damages. The males of dominant castes presented the highest amount of injuries, suggesting that these groups get involved more frequently in disputes. Possibly, reproductive events are a strong stimulus for the occurrence of fights in freshwater prawns since the greatest amount of injuries was observed in the period of reproductive peaks.

期刊介绍： Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation. As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above. The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis. With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
