Biogeography and evolutionary patterns of temperate deciduous forests in the Northern Hemisphere
Temperate deciduous forests of North America, west Eurasia, and east Eurasia share a common origin but were later separated by major geographic barriers. Here, we examine their diverging biodiversity...

Bottom line: the temperate deciduous biome shares a common origin, but each region carries its own evolutionary storyline.
And yet, we still lack full geographic and environmental coverage. More data (especially from under-sampled areas!) will be crucial to understand the biome’s global diversity

These patterns line up with each region’s long-term history:
East Eurasia stayed relatively stable, allowing many ancient plant lineages to persist.
North America went through bigger climatic and geological shake-ups, which likely produced forests with more evolutionarily distinctive species.

Why? Our models point to contrasting effects of past and present climate:
🌧️ In east Eurasia, high precipitation seasonality reduces evolutionary distinctiveness.
🌡️ In west Eurasia, temperature seasonality is the main limiting factor.

Another key metric: community evolutionary distinctiveness (CED).
This tells us how many evolutionarily unique or isolated lineages a community contains.
Surprise: North America comes out on top, its forests host especially distinctive plant lineages.

Between regions, the biggest evolutionary gap was between west Eurasia and east Eurasia.
Forests in North America and east Eurasia, on the other hand, shared more evolutionary history than we expected.

We also looked at phylogenetic turnover, in simple terms, how different the evolutionary histories of forest communities are within and between regions.
East Eurasia showed the most uniform evolutionary makeup, while West Eurasia had the strongest internal differences.

First big takeaway: East Eurasia is the champion of plant species richness, especially when it comes to trees and shrubs.
West Eurasia, meanwhile, shines in herb diversity.
Forests may look similar at first glance, but evolution played out very differently in each region.

We pulled together ~9600 vegetation plots from across the Northern Hemisphere.
(Important note: this isn’t a complete sampling of the entire biome; these are the best available plot data, but big gaps remain!)
