Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...

Second contribution to the sawflies of Belső Somogy (Hymenoptera: Symphyta) [PDF]

open access: yes, 2018
105 species were collected in Belső Somogy. With the present results, the known number of sawflies of this area increased up to 164. 11 rare species were captured: Pamphilius marginatus (Serville, 1823), Dolerus (Cyperolerus) anticus ssp.

Effects of landscape fragmentation at a fine scale on Mediterranean mountain grassland plant diversity

open access: yesEcosphere, Volume 16, Issue 10, October 2025.
Abstract European mountain grasslands are affected by abandonment and are being colonized by shrubs and forest. Grassland fragmentation is caused when the forest matrix grows, and surrounding grassland is split into fragments. Multiple studies have been done on grassland fragmentation but in anthropic matrices.

Interacting effects of invasion and soil microbes on Douglas‐fir seedling response to drought

open access: yesEcosphere, Volume 16, Issue 10, October 2025.
Abstract Global change is affecting native species and communities through multiple anthropogenic drivers which likely interact, complicating our ability to predict the net effects of global change. In the Pacific Northwest region (USA), Cytisus scoparius (L.) Link (Scotch broom) invasion has dramatically altered many ecosystems, including postharvest ...

Effect of a Prescribed Fire on Herbage Production in Southwestern Ponderosa Pine on Sedimentary Soils [PDF]

open access: yes, 1984
An area burned by prescription in 1977 and a nearby unburned area were measured in 1974 and 1980 to determine effects of the burn on herbage and forage production. Herbage production on the burned area increased significantly in 1980 over its 1974 level,

Contrasting Species Richness in Patches of Alternative Foundation Species Suggests a Framework for Understanding Species of Unusual Effect

open access: yesJournal of Vegetation Science, Volume 36, Issue 5, September/October 2025.
In a southeastern USA pine savanna, groundcover patches dominated by bracken ferns or gallberry shrubs have lower diversity relative to native bunchgrass areas. We hypothesize that relative to one another at our site, whereas bunchgrasses are diversity‐enhancing Species of Unusual Effect (SUEs), bracken and gallberry are diversity‐inhibiting SUEs—each ...
