The civil war in Mozambique led to the collapse of large-mammal populations and the spread of the invasive plant Mimosa pigra. Experimental exclosures and DNA metabarcoding are used to show how trophic rewilding since the end of the war has reduced the invasive population.
Predicting ecological niche space and ecosystem function from morphological traits is challenging. Here, the authors show that avian trophic diversity can be reduced to four dimensions, based on nine key morphological traits, which reflects convergence of trait combinations.
Left–right symmetry in vertebrates is established during development by different mechanisms, including motile cilia. Here, the authors show asymmetric expression of a Nodal paralogue in the left–right organizer in two reptilian embryos, which do not have motile cilia.
