| Open AccessLong-range atmospheric transport of microplastics across the southern hemisphere
Airborne microplastics (MPs) are observed over the Southern Ocean and Antarctica. MPs morphology is the primary factor influencing the hemispheric transport to these remote areas that may suffer increased pollution from urbanized, land-based sources.

| Open AccessQuantifying global colonization pressures of alien vertebrates from wildlife trade
This study compiled a comprehensive global database on live terrestrial vertebrate trade and used it to investigate traded alien species. The authors identify 7,780 species involved in trade globally and show that countries with greater trading power, higher incomes and larger human populations import more alien species, which emerge as hotspots for establishment richness of aliens.

| Open AccessDiurnal temperature range as a key predictor of plants’ elevation ranges globally
This study relates 88,000 elevation range sizes of vascular plants in 44 mountains to short-term and long-term temperature variation. The authors finding of decreasing elevation range sizes with greater diurnal temperature range supports a novel biodiversity hypothesis and indicates increased extinction risk of continental species.

The authors map beliefs in climate change and their correlates in Latin America.
