Butterfly Fauna of Central Panama During an El Niño Period: Preliminary Insights on Diversity Patterns

open access: yesPsyche: A Journal of Entomology, Volume 2025, Issue 1, 2025.
Panama’s rich butterfly diversity, owing to its position as a biological bridge between North America and South America, remains insufficiently documented. To contribute faunistic data from this region, we conducted a noninvasive modified Pollard walk survey of adult butterflies over 20 days, between May 20 and June 14, 2023, focusing on central Panama:

Rainfall but not selective logging affect changes in abundance of tropical forest butterfly in Sabah, Borneo [PDF]

open access: yes, 2003
We investigated the effects of rainfall on the distribution and abundance of the satyrine butterfly Ragadia makuta in selectively logged and unlogged forest on Borneo. In 1997-98, there was a severe El Nino-Southern Oscillation (ENSO) drought, and annual

Landscape effects on dispersal‐related traits in a sedentary butterfly in agricultural landscapes

open access: yesEcological Entomology, Volume 49, Issue 6, Page 925-938, December 2024.
Landscape heterogeneity in agricultural landscapes affected dispersal‐related traits in the butterfly Coenonympha pamphilus Configurational and compositional landscape heterogeneity affected butterfly traits in a complex manner; high proportions of crop fields were associated with phenotypes enhancing dispersal Our results suggest that limitations on ...

Eco‐evolutionary origins and diversification in a megadiverse hotspot: Arthropods in the Greater Cape Floristic Region

open access: yesEcology and Evolution, Volume 14, Issue 8, August 2024.
The Greater Cape Floristic Region at the southern tip of Africa is a global megadiversity hotspot. The region's biodiversity has been driven by a long history of topographic, climatic, and sea level change coupled with geological uplift, and without being exposed to any major climate events such as glaciations since the breakup of Gondwana.

Strong differences in egg heat tolerance between closely related lowland and alpine butterfly species

open access: yesEcological Entomology, Volume 49, Issue 4, Page 598-603, August 2024.
Coenonympha species replace each other along the elevational gradient despite their similar phenotypes, phenology and host plants. Estimated egg heat tolerance ranges strongly differed between lowland and alpine Coenonympha species but not between populations of the same species from different elevations. Species‐specific egg heat tolerance range could
