Abstract

Southeast Australian saltmarshes are endangered ecological communities under threat from various anthropogenic factors including climate change. As climate change drives sea-level rise mangrove encroachment and saltmarshes are squeezed at their landward edge, our lack of knowledge of the ecological interactions and any associations between saltmarsh vegetation and fauna becomes concerning, especially given the importance of saltmarsh for fisheries and as a blue carbon habitat. This study investigated the association of saltmarsh vegetation and the abundance and movement of gastropods in a typical coastal saltmarsh at Patonga, New South Wales, Australia. Densities of the gastropods including Phallomedusa solida, Ophicardelus spp. and Littoraria luteola were significant in vegetated Salicornia quinqueflora and least in unvegetated saltmarsh and areas where mangroves had encroached. Experiments that translocated Ophicardelus spp. and manipulated cover revealed that these patterns were actively maintained by Ophicardelus spp., which dispersed up to 40 cm and 1.4 m after 3 and 24 h, respectively, away from unvegetated saltmarsh and mangroves. The results of this study suggest that both habitat and cover influence the abundance and movement of gastropod dynamics in southeastern saltmarsh. Given future anticipated saltmarsh loss, further investigations are needed on the unknown functional role of gastropods in saltmarsh ecosystems.

澳大利亚东南部盐沼中腹足类动物的丰度和移动对植被和覆盖物的影响
澳大利亚东南部盐沼是濒危生态群落,受到包括气候变化在内的各种人为因素的威胁。随着气候变化导致海平面上升、红树林蚕食以及盐沼向陆地边缘的挤压,我们对盐沼植被和动物之间的生态相互作用和关联缺乏了解,尤其是考虑到盐沼对渔业和蓝碳栖息地的重要性,这种情况就更令人担忧了。本研究调查了澳大利亚新南威尔士州帕通加典型沿海盐沼中盐沼植被与腹足类动物的数量和移动之间的关系。在有植被的五叶盐沼中,腹足类动物(包括 Phallomedusa solida、Ophicardelus spp.和 Littoraria luteola)的密度很高,而在无植被盐沼和红树林侵占的区域,腹足类动物的密度最低。通过转移 Ophicardelus spp.和控制覆盖度的实验发现,Ophicardelus spp.能积极维持这些模式,在离开无植被盐沼和红树林 3 和 24 小时后,Ophicardelus spp.分别散布到 40 厘米和 1.4 米处。这项研究的结果表明,生境和植被都会影响东南部盐沼中腹足类动物的数量和移动。鉴于未来盐沼的预期消失,需要进一步调查腹足类动物在盐沼生态系统中的未知功能作用。

期刊介绍: Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere. Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region. Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
