Asteroidea

open access: yes, 2023
Antarctic Asteroidea: Morphological trends between deep-sea versus shallow taxa Depth has played an important role in the diversification of different groups of deep-sea Asteroidea. For example, the widely occurring Atlantic species Zoroaster fulgens Thomson, 1873 was found to display different morphotypes present at different depths (Howell et al ...

Diverging Food Web Functioning Around Southampton Island, Nunavut: The Influence of Primary Production Supply and Bathymetry. [PDF]

open access: yesEcol Evol
Southampton Island hosts two distinct benthic sub‐webs, north and south. North is deeper, phytoplankton‐driven; South is shallower, more ice‐algae driven. North benthos: bottom‐up control, four trophic levels including apex predators. South benthos: walrus top‐down control, trophic truncation to three levels.

Examining Marine Assemblages Across an Inverse Salinity Gradient. [PDF]

open access: yesMol Ecol
ABSTRACT Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia.
