Abstract
The aggregation of conspecifics in the invasive shrimp Palaemon macrodactylus could be driven by either patchy environmental conditions or conspecific attraction. This study aimed to determine whether the observed grouped distribution in natural conditions results from gregarious behavior and the type of cue used by shrimp to locate conspecifics. Four experiments were conducted during the non-reproductive season in which a focal shrimp was given the choice between a zone with cues of conspecifics or an empty zone. The cues permitted in each experiment encompassed visual and chemical cues, exclusively visual cues, exclusively chemical cues and a control devoid of any visual or chemical cues. The results indicated that focal shrimps exhibited a preference for conspecific zones when exposed to chemical cues alone or in combination with visual cues. However, visual cues alone were insufficient to induce grouping with their peers. The value of this trait is discussed along with other behavioral characteristics of the species as a possible explanation for its success as an invader.
期刊介绍：
The Journal of Zoology publishes high-quality research papers that are original and are of broad interest. The Editors seek studies that are hypothesis-driven and interdisciplinary in nature. Papers on animal behaviour, ecology, physiology, anatomy, developmental biology, evolution, systematics, genetics and genomics will be considered; research that explores the interface between these disciplines is strongly encouraged. Studies dealing with geographically and/or taxonomically restricted topics should test general hypotheses, describe novel findings or have broad implications.
The Journal of Zoology aims to maintain an effective but fair peer-review process that recognises research quality as a combination of the relevance, approach and execution of a research study.
