The immature stages and biology of two Xenapates species in West Africa (Hymenoptera, Tenthredinidae) [PDF]

open access: yes, 2016
The immature stages and host plants of Xenapates Kirby, 1882 were hitherto unknown. We describe the larvae, prepupae and pupae of X. braunsi (Konow, 1896) and X. gaullei (Konow, 1896), and record observations on aspects of their biology. The relationship

Seasonal variation in wild pig (Sus scrofa) diet revealed by DNA metabarcoding

open access: yesWildlife Society Bulletin, EarlyView.
Using DNA metabarcoding of fecal samples, we investigated the diet of wild pigs at an extensive bottomland hardwood forest ecosystem within Felsenthal National Wildlife Refuge in Southern Arkansas. We found that wild pig diet was highly diverse and included at least 74 plant families and 106 genera and 23 species of vertebrates.

An updated taxonomic framework of Hymenochaetales (Agaricomycetes, Basidiomycota)

open access: yesMycosphere, 2023
Hymenochaetales is one of the fungal orders being mainly composed of wood-inhabiting macrofungi within Agaricomycetes , Basidiomycota . While the species diversity has been well explored, the classification of Hymenochaetales at the family level is still

Was the evolution of faster stomata driven by increased gas exchange rates rather than increasing water use efficiency?

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2355-2371, March 2026.
Summary Following changes in light flux, photosynthesis (A) typically adjusts more quickly than stomatal conductance (gs), which is dependent on changes in stomatal aperture. Faster stomatal responses are proposed to reduce water loss and enhance growth in dynamic light environments. Stomatal opening and closing parameters were determined in a range of

Taxonomic decomposition of the latitudinal gradient in species diversity of North American floras [PDF]

open access: yes, 2017
Aim: To test the latitudinal gradient in plant species diversity for self-similarity across taxonomic scales and amongst taxa. Location: North America. Methods: We used species richness data from 245 local vascular plant floras to quantify the slope and ...

Drivers of Hirola Antelope Diet Selection in Natural and Managed Habitat in Eastern Kenya

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Hirola (Beatragus hunteri) populations in eastern Kenya consumed 17 forage species, favoring the grass Chloris virgata and the forbs Commelina benghalensis and C. diffusa. Nutrient analyses showed that natural habitats offered higher phosphorus, magnesium, and digestibility, whereas managed sites provided more sodium, potassium, and crude protein, with
