| Open AccessPostglacial change of the floristic diversity gradient in Europe
Climate-induced poleward shifts in plant distributions could flatten latitudinal diversity gradients. However, here the authors show that the spread of forests after the last ice age reduced diversity in central and northern Europe, and that human land-use over the past 5000 years strengthened the latitudinal gradient in plant diversity.

| Open AccessGenome-wide analysis of Cushion willow provides insights into alpine plant divergence in a biodiversity hotspot
Exceptional alpine plant diversity exists in the Hengduan Mountains. Here, through genome assembly and population genomics studies, the authors find notable intraspecific divergence among Cushion willow populations isolated by the sky island-like habitats and consider it contributes to speciation and biodiversity.

| Open AccessClimate shapes mammal community trophic structures and humans simplify them
Broad scale patterns in the distribution of animal community functional properties could be determined by climate and disrupted by human activities. Here the authors show global patterns in large-mammal trophic structure related to climate variation, which human activities simplify in predictable ways.

| Open AccessGlobal mycorrhizal plant distribution linked to terrestrial carbon stocks
Mycorrhizas—mutualistic relationships formed between fungi and most plant species—are functionally linked to soil carbon stocks. Here the authors map the global distribution of mycorrhizal plants and quantify links between mycorrhizal vegetation patterns and terrestrial carbon stocks.

| Open AccessPredicted climate shifts within terrestrial protected areas worldwide
Protected areas are important refugia for wildlife, so if climate conditions within them change, wildlife could lose critical suitable habitat. Here the authors calculate the projected gain and loss of climate conditions within terrestrial protected areas worldwide.

| Open AccessExtinction debts and colonization credits of non-forest plants in the European Alps
Mismatches between the pace of climate change and plant responses may lead to delayed upslope shifts or extinction of mountain species. Here the authors investigate 135 alpine plant species, finding that extinction debts are more common among cold-adapted plants and colonization credits among warm-adapted plants.

| Open AccessAlternative ecological strategies lead to avian brain size bimodality in variable habitats
Large brains are expected to be beneficial in variable environments by enabling flexible behavioral responses. Here, the authors show that relative brain size in birds is bimodally distributed in colder, seasonal environments, suggesting that both large and small brains can be adaptive solutions to harsh conditions.

| Open AccessNew Eocene primate from Myanmar shares dental characters with African Eocene crown anthropoids
Recent fossil findings have suggested that anthropoid primates originated in Asia before dispersing into Africa. Here, Jaeger and colleagues describe a new fossil Asian primate, Aseanpithecus myanmarensis, that they interpret as a closer relative of African crown anthropoids.

| Open AccessThe determinants of genetic diversity in butterflies
Theory suggests that neutral genetic diversity is determined by census population size, but this is not observed empirically. Here, the authors show that in butterflies, neutral genetic diversity correlates with both body size and chromosome number, suggesting that linked selection is also an important factor.

The expansion of grassland plant diversity is thought to have facilitated diversification of herbivorous insects. Here, the authors show opposing evolutionary dynamics in a clade of African grasses and associated stemborers, opposing the hypothesis about grasslands as a 'cradle' of herbivore diversity.

Mass extinctions are thought to produce ‘disaster faunas’, communities dominated by a small number of widespread species. Here, Button et al. develop a phylogenetic network approach to test this hypothesis and find that mass extinctions did increase faunal cosmopolitanism across Pangaea during the late Palaeozoic and early Mesozoic.

Symbiosis with nitrogen-fixing bacteria (rhizobia) aids the growth of many legume species, but may also restrict their ability to colonize new regions lacking suitable rhizobia. Here, the authors show that symbiotic legumes are indeed less likely to become established in new regions than their non-symbiotic relatives.
