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

Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.
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.

, 2002
India has a diverse caecilian fauna, including representatives of three of the six currently recognized families, the Caeciliidae, Ichthyophiidae, the endemic Uraeotyphlidae, but previous molecular phylogenetic studies of caecilians have not included ...

Protected Areas Have Not Halted Macrophyte Biodiversity Loss and Eutrophication in Northwest German Standing Waters

Journal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
Since the mid‐20th century, mean site‐level macrophyte richness declined by more than a quarter across 119 standing waters of various types in northwest Germany. Within protected areas, richness was consistently higher but declined at similar rates. Communities shifted towards eutrophic‐hypertrophic indicators, underscoring the need for catchment‐wide ...

Vegetation community recovery on restored bottomland hardwood forests in northeast Indiana, USA

Integrated Environmental Assessment and Management, Volume 20, Issue 6, Page 1917-1938, November 2024.
Abstract Vegetation communities in restored bottomland hardwood forests in northeast Indiana were studied 6–21 years after restoration to assess progress toward restoration objectives. The study focused on four sites that were restored to compensate for resource injuries after contaminant releases.

Commodity risk assessment of Petunia spp. and Calibrachoa spp. unrooted cuttings from Costa Rica

EFSA Journal, Volume 22, Issue 11, November 2024.
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica.

International Biological Flora: Trapa natans†

Journal of Ecology, Volume 112, Issue 10, Page 2386-2420, October 2024.
The water caltrop (Trapa natans L.) was once widely distributed in its native range, but is in some part (i.e. Europe) nowadays very rare, highly threatened and of conservation concern for still unknown reasons. It has been introduced beyond its native range (e.g.
