Última Predation has no competition: factors influencing space and resource use by echinoids in deep-sea coral habitats, as evidenced by continuous video transects ArchiMer Stevenson, Angela; Mitchell, Fraser J. G.; Davies, Jaime S.. Predation and competition are highly influential factors determining space use in foraging animals, and ultimately contribute to the spatial heterogeneity observed within habitats. Here we investigated the influence of competition and predation on space and resource use via continuous video transect observations – a tool that has not previously been employed for this purpose. This study therefore also evaluates video data as a pragmatic tool to study community interactions in the deep sea. Observations were compiled from 15 video transects spanning five submarine canyons in the Bay of Biscay, France. Substrate choice, positioning on the coral, echinoid aggregate size, and the presence/absence of predators (e.g. fish and decapods) as well as competitors...

G.. Patterns of habitat use by animals and knowledge of the environmental factors affecting these spatial patterns are important for understanding the structure and dynamics of ecological communities. Both aspects are poorly known for deep-sea habitats. The present study investigates echinoid distributions within cold water coral (CWC) habitats on continental margins off France, Australia, and New Zealand. It further examines the influence of habitat-related variables that might help explain the observed distribution of echinoid taxa. Six echinoid taxa were examined from video and photographic transects to reveal taxon-specific distribution patterns and habitat-related influences. The Echinoidea were found in all habitats studied, but tended to aggregate in...

Ano: 2018 URL: https://archimer.ifremer.fr/doc/00423/53476/56749.pdf First record and range extension of the deep-sea urchin Hygrosoma petersii (A. Agassiz, 1880) (Echinodermata, Echinoidea) for the southern Caribbean Boletín de Investigaciones Yepes-Gaurisas,Daniela; Guerrero-Correa,Giovvana M.. ABSTRACT Hygrosoma petersii (A. Agassiz, 1880) is a regular deep-sea urchin from the family Echinothuriidae that has undergone numerous taxonomic changes throughout history. It is characterized by the presence of tridentate pedicellariae with spoon-shaped valves with a serrated edge. The geographic distribution of Hygrosoma petersii is extended to the Colombian Caribbean, as the southernmost record of the Caribbean Sea. Species description and, for the first time, Scanning Electron Microscopy (SEM) photographs of its pedicellariae and sphaeridia are presented, comparing it with its Caribbean congeners.
