Has the Earth’s sixth mass extinction already arrived? E MSY (extinctions per million species-years, as defined in refs 15 and 27) In this approach, background rates are estimated from fossil extinctions that took place in million-year-or-more time bins
Current Extinction Rate 10 Times Worse Than Previously . . . Previous estimates that relied on fossil data came up with a ballpark figure of 1 extinction per million species per year While fossil data provides us with direct estimates of extinction rates
Species-specific, pan-European diameter increment models . . . We compiled and used a dataset of diameter increment observations of over 2 3 million trees from 10 National Forest Inventories in Europe and a set of 99 potential explanatory variables covering forest structure, weather, climate, soil and nutrient deposition Diameter increment models are presented for 20 species species groups
Atlantic Striped Bass - Atlantic States Marine Fisheries . . . Since 1990, roughly 90% of total annual striped bass catch is released alive of which 9% are estimated to die as result of the fishing interaction (referred to as “release mortality” or “discard mortality”) In 2023, recreational anglers released alive an estimated 26 0 million fish, of which 2 3 million are assumed to have died
