Abstract
After 50 years, the dumping of red mud at the head of Cassidaigne Canyon (Southern France) was stopped in 2015. The area was surveyed in 2021 with an ROV at depths of 440–630 m. Biological findings reported here (images, sampling) have been obtained during a single ROV transect in the heavily impacted zone. In spite of the industrial waste deposit, a diverse faunal assemblage has persisted at the canyon head. Bioconstruction comprising large deep-sea oyster shells, scleractinian corals and hexactinellid sponge skeletons provides elevate and complex substrates for other organisms. Among the more significant findings, three live specimens of Neopycnodonte zibrowii Gofas, C. Salas & Taviani, 2009, previously only known as dead shells in that canyon, were documented and the rarely observed stenopodid shrimp Odontozona edwardsi (Bouvier, 1908) has been sampled (first record in the Mediterranean) and DNA barcoded.
经过50年的发展，2015年，法国南部卡西岱涅峡谷的红泥倾倒被停止。该地区于2021年使用ROV进行了调查，深度为440-630米。本文报告的生物发现(图像、采样)是在严重受影响区域的单个ROV样带中获得的。尽管有工业废料的沉积，峡谷的顶端仍然有多种多样的动物群落。由大型深海牡蛎壳、硬核珊瑚和海绵体骨架组成的生物结构为其他生物提供了高级和复杂的底物。在更重要的发现中，三个活的Neopycnodonte zibrowii Gofas, C. Salas &Taviani, 2009年，以前只知道该峡谷的死壳，被记录在案，并对罕见的窄足虾Odontozona edwardsi (Bouvier, 1908年)进行了采样(地中海的第一次记录)并进行了DNA条形码。
期刊介绍：
Marine Biodiversity is a peer-reviewed international journal devoted to all aspects of biodiversity research on marine ecosystems. The journal is a relaunch of the well-known Senckenbergiana maritima" and covers research at gene, species and ecosystem level that focuses on describing the actors (genes and species), the patterns (gradients and distributions) and understanding of the processes responsible for the regulation and maintenance of diversity in marine systems. Also included are the study of species interactions (symbioses, parasitism, etc.) and the role of species in structuring marine ecosystem functioning.
Marine Biodiversity offers articles in the category original paper, short note, Oceanarium and review article. It forms a platform for marine biodiversity researchers from all over the world for the exchange of new information and discussions on concepts and exciting discoveries.
- Covers research in all aspects of biodiversity in marine ecosystems
- Describes the actors, the patterns and the processes responsible for diversity
- Offers peer-reviewed original papers, short communications, review articles and news (Oceanarium)
