An inverse latitudinal gradient in intraspecific genetic diversity of a dominant ant in the neotropical savanna

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Although latitudinal gradient of diversity (LGD) is a biogeographic pattern widely shown for distinct animal groups, some display the opposite pattern, with biodiversity peaking away from the equator. These inverse gradients may result from drivers that also overlap with extrinsic factors shaping genetic diversity across taxa, a level of ...

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

Ecological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...

Genomics‐Based Approaches to Ant Monitoring in Land Management: Validation of COI Metabarcoding Primers

Environmental DNA, Volume 8, Issue 2, March/April 2026.
We validated ant‐specific COI metabarcoding primers using in silico, in vitro and in situ analyses, identifying assays that improve ant detection from mock communities, spike‐in tests and soil eDNA. The recommended assays reduce reliance on taxonomic expertise and enable scalable, high‐throughput ant biomonitoring for land‐management applications ...

Ant‐mediated seed dispersal in the Poaceae: Evidence of myrmecochory in green foxtail (Setaria viridis) and giant foxtail (Setaria faberi)

Plant Species Biology, Volume 41, Issue 1, January 2026.
Model systems have been developed for certain mutualistic interactions, such as pollination, root nodules, and mycorrhizal symbiosis, advancing our understanding of these forms of mutualism. However, in the area of seed dispersal mutualism, a model system has been lacking. Here, we provide evidence of ant‐seed dispersal mutualism in Setaria viridis and
