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 ...

INDEPENDENT ORIGINATION OF FLORAL ZYGOMORPHY, A PREDICTED ADAPTIVE RESPONSE TO POLLINATORS: DEVELOPMENTAL AND GENETIC MECHANISMS [PDF]

open access: yes, 2016
Observations of floral development indicate that floral organ initiation in pentapetalous flowers more commonly results in a medially positioned abaxial petal (MAB) than in a medially positioned adaxial petal (MAD), where the medial plane is defined by ...

The Linnaean revolution – A history of the Natural System

open access: yesTAXON, Volume 74, Issue 5, Page 1011-1034, October 2025.
Abstract A very brief history of the Natural System (NS) is presented, focusing on angiosperms. The account is divided into four parts. The first, “Setting the stage”, gives an outline of my understanding of evolutionary ontology and how this reflects on taxonomy.

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

open access: yesConservation 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.
