摘要

2018年12月下旬，在新西兰奥特罗阿北岛陶朗加港Pilot Bay /Te Ika-a-Māui发生了海星消耗事件。47颗小行星Coscinasterias muricata Verrill, 1867年，最大直径50 - 150毫米，在领航员湾西北端约70米的区域内，在退潮时以不同的状态在岩石上和岩石之间被发现。消耗事件发生在短暂的大雨之后(前24小时为97.8毫米)，持续时间很短，三天后没有观察到受影响的海星。受影响的muricata可能对水质变化，特别是盐度变化的适应能力较低。然而，造成这一浪费事件的原因仍未得到解决。这些机会主义数据表明，这种性质的小规模海星损耗事件可能很容易被忽视，因为它们的短暂性。

An ephemeral sea star ( Coscinasterias muricata ) wasting event at Tauranga, New Zealand

During late December 2018 a sea star wasting event occurred at Pilot Bay, Tauranga Harbour, North Island/Te Ika-a-Māui, Aotearoa New Zealand. Forty-seven specimens of the asteroid Coscinasterias muricata Verrill, 1867, with a maximum diameter of 50 - 150 mm, were found in varying states of wasting on and between rocks at low tide over an area of ∼70 m at the NW end of Pilot Bay. The wasting event followed a brief period of heavy rain (97.8 mm during the previous 24 h) and was short-lived, with no affected sea stars observed after three days. The affected C. muricata may have had low resilience to changes in water quality, particularly salinity. However, the cause of this wasting event remains unresolved. These opportunistic data suggest that small scale sea star wasting events of this nature may be easily overlooked due to their ephemeral nature.

期刊介绍： Aims: The diversity of the fauna of the southern continents and oceans is of worldwide interest to researchers in universities, museums, and other centres. The New Zealand Journal of Zoology plays an important role in disseminating information on field-based, experimental, and theoretical research on the zoology of the region.
