Marked Variability in Distance‐Decay Patterns Suggests Contrasting Dispersal Ability in Abyssal Taxa

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim We assess the role of spatial distance and depth difference in shaping beta diversity patterns across abyssal seascape regions. We measured the decrease of faunistic similarity across the northeast Pacific seafloor, to test whether species turnover rates differ between deep and shallow‐abyssal biogeographical provinces and whether these ...
