Ecology and Evolution, Volume 16, Issue 7, July 2026.We asked whether variation in the willingness of congeneric species to secrete chemical defenses is associated with high between‐species differences in body size, levels of leg loss (as a proxy for engagement in another defensive strategy), and participation in social roosting with conspecifics and congenerics.

Two New Species of Combretaceae from Puntarenas, Costa Rica
Novon, 1995 Two new species of Combretaceae are described from Costa Rica.

Systematic Entomology, Volume 51, Issue 3, July‐September 2026.Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.

People and Nature, Volume 8, Issue 6, Page 1943-1956, June 2026.Abstract Remote sensing studies show that ephemeral forest regeneration is widespread in the tropics, limiting the climate and biodiversity benefits from net increases in forest cover. Socioeconomic, biophysical and landscape variables can help explain the spatial distribution of reforestation reversals.
