A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

open access: yesAustral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Genetic diversity is key to a nature‐positive future

open access: yesPeople and Nature, Volume 7, Issue 11, Page 2578-2584, November 2025.
Abstract Nature‐positive describes the concept of halting and then reversing the loss of biodiversity in a manner that is equitable to all, particularly indigenous peoples and local communities. Genetic diversity is the foundational component of biodiversity, underpinning species and ecosystem diversity.

Sustentabilidade dos recursos florestais em Portugal: o que aprendemos com o pinheiro-bravo [PDF]

open access: yes, 2017
O desenvolvimento sustentável de uma espécie depende da diversidade genética presente nas populações. A conservação dos recursos genéticos, devido à maior resiliência da espécie quando a sua variabilidade genética é maior, promoverá a salvaguarda da ...

Integrating target capture with whole genome sequencing of recent and natural history collections to explain the phylogeography of wild‐growing and cultivated cannabis

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1771-1788, November 2025.
Cannabis has been used by humans for millennia, resulting in diverse landraces and uses. Its complex legal status and economic importance make sampling wild‐growing populations difficult, limiting past studies to modern cultivars with low genetic diversity. Our research provides crucial insights into the genetic diversity of wild‐growing and cultivated
