Declining resilience of North America’s plant biomes may
Declining resilience of North America’s plant biomes may be a sign of a mass extinction last seen nearly 13,000 years ago, experts warn. Plant biome resilience is lower than the mass extinction


North American plant biome resilience ‘hints at mass
A mass extinction not seen in 13,000 years may be on the horizon due to human activity and climate change, cautions a new study. The warning comes as the resilience of North American’s plant biomes is declining, suggesting present-day landscapes are ‘primed to herald a major extinction event.’ Scientists analyzed over 14,000 fossil pollen samples […]

The resilience of North America’s plant biomes is declining — indicating that today’s landscapes are “primed to herald a major extinction event” not seen since the retreat of glaciers and arrival of humans 13,000 years ago, scientists reported in a new study published in the journal Global Change Biology.


Quaternary extinction event – Wikipedia
The Quaternary period (from 2.588 ± 0.005 million years ago to the present) saw the extinctions of numerous predominantly megafaunal species, which resulted in a collapse in faunal density and diversity and the extinction of key ecological strata across the globe. The most prominent event in the Late Pleistocene is differentiated from previous Quaternary pulse extinctions by the widespread …

Similarities are seen in Australia with first human colonization at about 50,000 years ago and the extinction of the continental megafauna within 4000 years on the mainland (Gillespie, 2008, Roberts et al., 2001) and slightly later on Tasmania (Turney et al., 2008). The association of megafauna extinctions and human arrival in Eurasia is more …

The plant may then deplete resources that are crucial for a different species, which then starts to die out. As that species dies out, it can affect still other species. Indeed, removing just one species can have huge consequences for all other species in the ecosystem, sending the entire ecosystem into a completely different system state.
