Wei Lin and Chengjin Chu, Sun Yat-sen University, discuss their article: Interannual rainfall variability promotes species coexistence primarily through relative nonlinearity in interaction strength Ecologists often study species coexistence as if environmental conditions remain constant over time. But in the real world, rainfall can vary dramatically from one year to the next. Does this variability…
Frederik Mortier, Ghent Universit, discusses his article: Polyploid—diploid coexistence in the greater duckweed Spirodela polyrhiza Polyploid establishment is not as easy as it looks Polyploidy, when organisms have extra sets of chromosomes due to whole-genome duplication, is surprisingly common, especially in plants. Polyploidy can be a dramatic mutation with a huge effect on plant traits,…
Dina in ‘t Zandt discusses her recent paper Local soil legacy effects in a multispecies grassland community are underlain by root foraging and soil nutrient availability. Find out more about their soil legacy experiments and how their results differed from the theory. Biodiversity plays a key role in ecosystem structure and function, with plant community…
A paper in Early View in the Journal (Trait evolution and the coexistence of a species swarm in the tropical forest understorey) by Brian Sedio and colleagues explores how a plant species in the genus Psychotria coexist in the understorey of tropical rainforests in Panama. Read the abstract here. I caught up with Brian last week to…
