摘要

摘要:在墨西哥湾东部有大量的大群鱼。沙质环境的主要生物扰流器。在本实验室研究中,将田鼠置于实验室围栏中,在不同的处理(一天中的时间、大小、掠食性线索、摄食史、密度)下,并录制3-4小时的视频。我们分析了五个变量:前进加上旋转运动的时间(movement),单独前进运动的时间(Progression),被沙子覆盖的时间(covered),移动的距离(distance)以及移动的速度(Speed)。在一天的时间治疗中,没有发现任何变量的饮食节奏模式。大型个体的覆盖频率较低,移动距离更远,速度几乎是小型个体的两倍。喂养历史和掠夺性线索都没有影响。较低密度的聚合体在移动和进程中花费更多时间。较大和较小的个体都对生物扰动活动有贡献,可能在24小时内影响栖息地。

Movement and behavior of the sand dollar Mellita tenuis (Echinodermata: Echinoidea)
ABSTRACT Mellita tenuis occurs in large aggregations in the eastern Gulf of Mexico, and are. major bioturbators of sandy environments. In this laboratory study, M. tenuis were placed in a laboratory enclosure under varying treatments (Time of Day, Size, Predatory Cues, Feeding History, Density), and video recorded for 3–4 hr. Five variables were analyzed: time in forward plus rotational movement (Movement), time in forward movement alone (Progression), time covered by sand (Covered), distance moved (Distance), and how fast they moved (Speed). There was no diel rhythm pattern found for any of the variables studied amongst Time of Day treatments. Large individuals covered less often, moving further and nearly two times faster than small individuals. Neither Feeding History nor Predatory Cues had an effect. Lower density aggregations spent more time in Movement and Progression. Both larger and smaller individuals contribute to bioturbation activitiespotentially impacting the habitat across 24 hr.

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).
