Forest Type as a Key Driver of Butterfly Species Diversity

Psyche: A Journal of Entomology, Volume 2026, Issue 1, 2026.
Forest types and complex vegetation structures are key factors in promoting butterfly diversity. While considerable studies represent the checklists of butterfly species across various forest types in Bangladesh, the influence of different forest types on butterfly species diversity remains unexplored. To explore this, we conducted the study from April

Combining spaceborne lidar from the Global Ecosystem Dynamics Investigation with local knowledge for monitoring fragmented tropical landscapes: A case study in the forest–agriculture interface of Ucayali, Peru

Ecology and Evolution, Volume 14, Issue 8, August 2024.
We employed a co‐production approach leveraging spaceborne lidar and local knowledge to investigate the structural characteristics of the forest‐agriculture interface in Ucayali, Peru. Results indicated higher relative height ratios (RH50/RH95 and RH75/RH95) for mature forest compared to secondary forest (p < .0001), even after accounting for the ...
