Both rare and common species make unique contributions to functional diversity in an ecosystem unaffected by human activities

Abstract: Aim: Rare species typically contribute more to functional diversity than common species. However, humans have altered the occupancy and abundance patterns of many species-the basis upon which we define "rarity." Here, we use a globally unique dataset from hydrothermal vents-an untouched ecosystem-to test whether rare species over-contribute to functional diversity. Location: Juan de Fuca Ridge hydrothermal vent fields, Northeast Pacific Ocean. Methods:We first conduct a comprehensive review to set up expectati… Show more

“…Locally, species and trophic diversities are typically low in areas of higher fluid flux, higher in areas of lower emissions, and even higher in more stable yet less productive adjacent environments without direct influence of vent fluid emissions (Govenar et al 2005, Gollner et al 2010, 2015 b , Sarrazin et al 2015, Zeppilli et al 2015, Sen et al 2016, Bell et al 2017, Plum et al 2017). To date, however, local functional diversity patterns remain largely unexplored in these ecosystems (but see Chapman et al 2018, 2019). Coupling taxonomic and functional‐trait–based approaches can provide crucial insights into processes structuring faunal communities and their responses to global environmental changes and industrial impacts (McGill et al 2006).…”

“…Instead of exploiting photosynthetic pathways, vent animals are strongly dependent on energy from reduced compounds in hydrothermal fluid through chemosynthetic microorganisms (Jannasch, ). Deep‐sea hydrothermal vents therefore offer a compelling system for applying trait‐based approaches (e.g., see Chapman, Tunnicliffe, & Bates, ). Moreover, the distribution of hydrothermal‐vent communities has been shaped through geological and evolutionary time by the movement of tectonic plate boundaries (Ramirez‐Llodra, Shank, & German, ; Tunnicliffe, ).…”
