摘要

海草床由基础物种组成,为各种海洋生物提供重要的育苗场、觅食区和避难所。多种鱼类和无脊椎动物将海草作为重要的栖息地。德克萨斯州的矮海马(Hippocampus zosterae)是一个研究不足的物种,人们对其在这一区域的密度、分布和栖息地关系知之甚少。研究人员在得克萨斯州的 80 个地点收集了水体理化参数、底栖动物群落数据、栖息地数据和矮海马捕获量数据。目标物种的最高单位努力捕获量(CPUE)出现在阿兰萨斯湾(0.038/m2)。海龟草(Thalassia testudinum)的存在和覆盖率与矮海马的存在和 CPUE 之间存在正相关关系。在海草群落多样性和丰富度较高的地点,发现矮海马的频率更高,CPUE 也更高。在发现矮海马的地点,底栖生物群落也更加丰富、多样和物种丰富。这是首次对德克萨斯海岸矮海马分布情况进行的全面研究。在成熟、稳定和多样化的海草床附近,矮海马的数量通常较多。为保护矮海马而推荐的保护策略应优先保护已建立的成熟海草床。建议继续对该物种进行定向监测,以更好地了解其分布和种群状况。

Dwarf Seahorse (Hippocampus zosterae) Density, Distribution, and Habitat Use in Texas

Dwarf Seahorse (Hippocampus zosterae) Density, Distribution, and Habitat Use in Texas

Seagrass beds are composed of foundation species, providing essential nursery grounds, feeding areas, and refuge for various marine life. Several species of fish and invertebrates utilize seagrasses as essential habitat. The Dwarf Seahorse (Hippocampus zosterae) is an understudied species in Texas, and little is known about its density, distribution, and habitat associations in this area of their range. Physicochemical water parameters, nekton community data, habitat data, and Dwarf Seahorse catch data were collected at 80 sites in Texas. The highest catch per unit effort (CPUE) of the target species was in Aransas Bay (0.038/m2). There was a positive relationship between the presence and percent cover of turtle grass (Thalassia testudinum) and the presence and CPUE of Dwarf Seahorses. Dwarf Seahorses were detected more often and at a higher CPUE in locations with a higher seagrass community diversity and richness. The nekton community at sites where Dwarf Seahorses were detected was also more abundant, diverse, and species rich. This is the first comprehensive study of the distribution of the Dwarf Seahorse along the Texas coast. Dwarf Seahorses were generally found in higher abundances in association with mature, stable, and diverse seagrass beds. Recommended conservation strategy to protect Dwarf Seahorses should prioritize the protection of established and mature seagrass beds. Continued directed monitoring of this species is recommended to better understand their distribution and population status.

期刊介绍: Estuaries and Coasts is the journal of the Coastal and Estuarine Research Federation (CERF). Begun in 1977 as Chesapeake Science, the journal has gradually expanded its scope and circulation. Today, the journal publishes scholarly manuscripts on estuarine and near coastal ecosystems at the interface between the land and the sea where there are tidal fluctuations or sea water is diluted by fresh water. The interface is broadly defined to include estuaries and nearshore coastal waters including lagoons, wetlands, tidal fresh water, shores and beaches, but not the continental shelf. The journal covers research on physical, chemical, geological or biological processes, as well as applications to management of estuaries and coasts. The journal publishes original research findings, reviews and perspectives, techniques, comments, and management applications. Estuaries and Coasts will consider properly carried out studies that present inconclusive findings or document a failed replication of previously published work. Submissions that are primarily descriptive, strongly place-based, or only report on development of models or new methods without detailing their applications fall outside the scope of the journal.
