Nomenclatural notes on some European elm names (Ulmaceae)

TAXON, Volume 74, Issue 5, Page 1213-1216, October 2025.
Abstract The typification of the elm names Ulmus laevis, U. minor, and U. pumila is discussed. Ulmus laevis is lectotypified on a Pallas illustration published in his Flora Rossica. No original material could be located for U. minor and a neotype is designated (a specimen at SLBI). Ulmus pumila is lectotypified on a specimen in LINN.

Comparing the impacts of patch‐burn grazing on vegetation in two northern tallgrass prairies

Conservation Science and Practice, Volume 7, Issue 10, October 2025.
We evaluated two of the earliest and largest patch‐burn grazing projects in the eastern tallgrass prairie of Minnesota, an ecosystem that has undergone extensive fragmentation and invasion by non‐native species. Our results in grazed and ungrazed plots varied with differences in stocking rate and fire frequency.

Hydrology and Ecological Evolution in a Permafrost Region in Northeast China Since the Late Pleistocene

Ecology and Evolution, Volume 15, Issue 9, September 2025.
Continuous hydrology and ecological evolution records of permafrost regions in Northeast China since the late Pleistocene (30 cal. ka BP) are obtained. Responses of hydrology and ecosystem dynamics to the climate cycle on the millennial scale and regional environmental effects related to permafrost.
