Title: Insect Populations Collapse in Protected Nature Reserves

Link: https://news.slashdot.org/story/25/06/05/1955...

Insect populations are crashing in supposedly protected nature reserves
worldwide with climate change emerging as the primary driver of biodiversity
loss for the first time in human history. Ecologist Daniel Janzen, who has
monitored Costa Rica's Guanacaste conservation area since the 1970s,
documented the collapse through light trap photographs that showed 3,000 moth
species in 1978 versus virtually none today using identical methods. Similar
declines are occurring globally with flying insects dropping 75% across 63
German reserves in under 30 years, US beetle numbers falling 83% over 45
years, and Puerto Rico experiencing up to 60-fold biomass losses since the
1970s. Recent research published in BioScience found climate change now
drives decline in 91% of imperiled US species, narrowly surpassing habitat
destruction.
