Biology Discoveries
7 discoveries
Sixth Mass Extinction Evidence
2015 — Gerardo Ceballos, Paul Ehrlich
Comprehensive analysis showing that current vertebrate species extinction rates are up to 100 times higher than background rates, signalling a sixth mass extinction.
Environmental DNA (eDNA) Monitoring
2008 — Pierre Taberlet
Development of methods to detect species from trace DNA shed into water, soil, or air, enabling non-invasive biodiversity monitoring.
Discovery of Colony Collapse Disorder
2006 — Dennis vanEngelsdorp
Documentation and naming of the sudden mass disappearance of honey bee colonies, with losses exceeding 30% annually in affected apiaries.
Yellowstone Wolf Reintroduction
1995 — Douglas Smith, US Fish and Wildlife Service
Reintroduction of grey wolves to Yellowstone National Park after 70 years of absence, triggering a documented trophic cascade across the ecosystem.
Biodiversity Hotspots Concept
1988 — Norman Myers
Identification of 25 biodiversity hotspots — regions containing high concentrations of endemic species facing severe habitat loss.
IUCN Red List System
1964 — IUCN
Establishment of a standardised system for assessing and classifying the extinction risk of species worldwide, from Least Concern to Extinct.
Silent Spring and Pesticide Ecology
1962 — Rachel Carson
Publication documenting the devastating ecological effects of DDT and other synthetic pesticides, particularly bioaccumulation in food chains.
