Abstract

ABSTRACT The Gold Coast bay in eastern Australia has been hypothesised to be an important habitat, primarily for humpback whale (Megaptera novaeangliae) mother-calf pairs. Here we investigated relative distribution, and temporal patterns from 2,305 humpback whales between 2011 to 2017. The data were collected from whale-watching vessels using citizen science. We analysed seasonal presence of mother-calf pairs, dive times, direction of movement and location to determine habitat use of the bay as aresting area. In average aquarter of all sighted whales were mother-calf pairs with peaks of sightings each October. The recorded average dive time of 3.20 minutes was short compared to that in migratory corridors. Mother-calf pairs were sighted more often closer to shore relative to other pods. We compared our results to recognised breeding and resting grounds and found similar results, indicating that the Gold Coast bay may serve as an important stop-over for humpback whale mother-calf pairs.

座头鲸(Megaptera novaeangliae)母子在澳大利亚黄金海岸的存在和运动

澳大利亚东部的黄金海岸湾被认为是一个重要的栖息地，主要是座头鲸(Megaptera novaeangliae)母子的栖息地。在这里，我们调查了2011年至2017年期间2305头座头鲸的相对分布和时间模式。这些数据是利用公民科学从观鲸船上收集的。我们分析了母子对的季节性存在，潜水时间，运动方向和位置，以确定海湾作为栖息区域的栖息地使用。在所有被发现的鲸鱼中，平均有四分之一是母子对，每年10月是看到鲸鱼的高峰期。记录的平均潜水时间为3.20分钟，与迁徙走廊相比较短。相对于其他鲸群，母鲸和幼鲸往往更靠近海岸。我们将我们的结果与公认的繁殖地和休息地进行了比较，发现了类似的结果，表明黄金海岸湾可能是座头鲸母子对的重要中途停留地。

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).
