Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

open access: yesSystematic 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.

Varied motivations for secondary forest reclearing among landholders make forest persistence challenging

open access: yesPeople 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.
