Antarctic endophytes improve drought tolerance in lettuce plants
Climate change has limited the availability of water for irrigating crops throughout many regions of the world. Indeed, current models of climate change predict that arid

Paleo- and neo-endemism in a Mediterranean biodiversity hotspot
Relative phylogenetic endemism (RPE) is a phylogenetic measure of endemism allowing for differentiation between centres of paleo- and neo-endemism. Molina-Venegas et al. apply an

It’s World Wetland Day
Today, lakes, rivers, underground aquifers, swamps, marshes, wet grasslands, peatlands, oases, estuaries, deltas, tidal flats, mangroves, coral reefs, as well as fish ponds, rice paddies, reservoirs and salt pans and, as the rain hammers down, also my garden, celebrate World Wetlands Day today.

Population-level genetic variation and climate change in a biodiversity hotspot
Estimated future climate scenarios can be used to predict where hotspots of endemism may occur over the next century, but life history, ecological and genetic traits

Aluminium accumulation in a temperate accumulating plant
Although aluminium (Al) is toxic for the vast majority of angiosperm plants, high concentrations of Al (i.e., > 1,000 mg·kg-1 dry mass)

Endemism hotspots are linked to stable climatic refugia
What causes endemism hotspots? In a world of climate change, these refugia may be connected to areas of relative climate stability.

Holokinetic chromosomes beat selfish centromeres
In eukaryotic lineages with monocentric chromosomes, centromeres and centromeric histone H3 (CENH3) undergo a recurrent evolutionary conflict, whereby selfish centromeres subvert female meiosis, and CENH3 evolves

The effects of nitrogen form on root morphological and physiological adaptations of maize, white lupin and faba bean under phosphorus deficiency
Root morphological/physiological modifications are important for phosphorus (P) acquisition of plants under P deficiency, but strategies differ among plant species, and detailed studies on the

Active or passive? Specific-leaf-area plasticity responses
Liu et al. conducted a meta-analysis to test the hypothesis that shade-induced increases in specific-leaf-area (SLA) indicate an adaptive plant response to
