Discovering marine biodiversity in the 21st century

Actions to halt biodiversity loss generally benefit the climate

“…In the ocean, fishing wild species as the main source of seafood production is a major driver of biodiversity loss as a result of overexploitation, bycatch and destruction of habitats (IPBES, 2019a(IPBES, , 2019bRogers et al, 2020). Fishing can also impact carbon fluxes, by exporting ocean carbon to land and ultimately to the atmosphere that would otherwise be sequestered in the deep sea (Mariani et al, 2020;Sala et al, 2021).…”

Benthic biodiversity by baited camera observations on the Cosmonaut Sea shelf of East Antarctica

“…The Southern Ocean has become a hot area for global research on climate change and ecological evolution due to its harsh natural environment, fragile ecosystem, and sensitivity to climate change. There is a growing need for marine biodiversity baselines and monitoring data to assess ocean ecosystem health, especially that around Antarctica where data are rare (Costello et al, 2010;Levin et al, 2019;Rogers et al, 2020;Giddens et al, 2021).…”

Marine Invertebrate Neoextinctions: An Update and Call for Inventories of Globally Missing Species

“…I present here a revised and updated inventory of the current record of global marine invertebrate extinctions, as well as an appeal for the promulgation of lists of globally missing species. The threats to marine invertebrate diversity in highly vulnerable habitats that could lead to increasing numbers of extinctions in the 21st century, and the compelling rationales for understanding why extinctions matter, are not reviewed here, as these have been extensively discussed for the past two decades and more [8][9][10][11][12][13] (among many others). The burgeoning literature further flags the risks to specific threatened and endangered marine invertebrate taxa (for example, [14][15][16][17][18][19][20][21][22][23]).…”
