(2025), Marked Variability in Distance-Decay Patterns Suggests Contrasting Dispersal Ability in Abyssal Taxa. Global Ecol Biogeogr, 34: e13956. https://doi.org/10.1111/geb.139561466-8238https://hdl.handle.net/10347/40989We 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 patterns vary across functionally or taxonomically different biotic groups.eng© 2025 The Author(s).
