The Effects of Biome Stability During the Quaternary on Plant Diversity
We used machine learning to reconstruct global biome changes over the last 2.6 million years, revealing that tropical forests, deserts, and temperate forests were relatively stable, whereas northern Europe and North America experienced frequent biome shifts due to ice sheet expansions.

Proactively developing and geographically targeting coexistence measures before conflicts become entrenched can improve megafauna restoration success. Our work demonstrates how integrating spatial conflict indicators into individual‐based models enables forward‐looking simulations of range expansion to guide such measures and to assess how they might ...

ABSTRACT Recovering ancient DNA from environmental samples is transforming the way we understand historical ecosystems. While high‐throughput sequencing of the total DNA in environmental samples (shotgun metagenomic sequencing) reveals the taxonomic contents of these samples, the genetic signals of some taxa (e.g., eukaryotes) can be weak compared to ...

Across the last ~50,000 years (the late Quaternary) terrestrial vertebrate faunas have experienced severe losses of large species (megafauna), with most extinctions occurring in the Late Pleistocene and Early to Middle Holocene.

Total Numbers and Movements of Photo‐Identified Subantarctic (Type D) Killer Whales
ABSTRACT The distinctive Subantarctic (Type D) killer whale (DKW) (Orcinus orca) is a highly divergent and apparently inbred form previously known only from three mass strandings and several dozen at‐sea sightings, primarily from Patagonian toothfish (Dissostichus eleginoides) longline vessels in the southern Indian Ocean and from tourism vessels in ...

This paper presents a systems-level framework for understanding late Pleistocene megafauna extinctions across the Americas and other regions. Rather than treating extinction as the result of a single dominant cause, it argues that the observed geographic asymmetry, delayed extinctions, and selective survival patterns are best explained by the ...
