literature review was conducted to investigate marine global and local extinctions and their drivers; the review followed the PRISMA-EcoEvo guidelines. The data extracted was enhanced with status assessments from the IUCN Red List. We recorded local extinctions for 717 species, of which 18 were global extinctions. Most of these extinctions were recorded on very localized and sub-ecoregion ...
The recovery of Laurentian diversity hotspots after the Late Devonian mass extinction led to the onset of Permian hotspots, which eventually disappeared during the PermianTriassic mass extinction. Beneath the oceans surface, an unprecedented crisis is unfolding. Our marine ecosystemshome to millions of species and essential to human survivalare experiencing biodiversity loss at an alarming rate. Recent studies indicate that over 50% of marine populations have declined since 1970, with some species facing extinction within our lifetime. This rapid deterioration isnt just ... Global extinctions in the marine environment were mainly attributed to overexploitation, followed by invasive species, habitat destruction, trophic cascades, and pollution. Will there be a sixth mass extinction in the ocean? Between 20 and 24 marine extinctions, ranging from algal to mammal species, have occurred over the past 500 years. These relatively low numbers question whether the sixth mass extinction that is underway on land is also occurring in the ocean. Are marine extinctions global or local? A literature review was conducted to investigate marine global and local extinctions and their drivers; the review followed the PRISMA-EcoEvo guidelines. The data extracted was enhanced with status assessments from the IUCN Red List. We recorded local extinctions for 717 species, of which 18 were global extinctions. Can new extinction metrics be used to identify extinction reference points? However, uncertainties remain in detecting the disappearance of marine species and populations that can be addressed using new extinction metrics and methodologies to define conservation reference points and contextualize the current loss of marine biodiversity. Is marine defaunation causing a sixth mass extinction? This accelerated loss of marine biodiversity is consistent with growing reports of marine defaunation being caused by human activities (Harnik et al., 2012; McCauley et al., 2015), and may mark the beginning of a sixth mass extinction in the oceans. The impacts that extinction may have on marine ecosystems have been characterized by several seminal experiments in marine ecosystems. In the late 1960s, Robert Paine experimentally removed different species from several marine sites in the Pacific Northwest of the United States.
