Forgotten forbs: Standard vegetation surveys underrepresent ecologically and culturally important forbs in a threatened grassland ecosystem

Conservation Science and Practice, Volume 4, Issue 10, October 2022., 2022
We evaluated how the timing of vegetation sampling within the Pacific Northwest Bunchgrass ecosystem affected estimates of perennial forb abundance, richness, and floral density, with a focus on species of cultural significance to Indigenous people of the region.

Diet of a rare herbivore based on DNA metabarcoding of feces: Selection, seasonality, and survival

Ecology and Evolution, Volume 10, Issue 14, Page 7627-7643, July 2020., 2020
Diet and foraging behavior are the foundation of an herbivore's life history strategy and it is imperative that we know the species of plants they prefer. We used DNA metabarcoding techniques to noninvasively sample the threatened northern Idaho ground squirrel (Urocitellus brunneus) diet. We used three gene regions and found that diets differed on the

Repeated fire altered succession and increased fire behavior in basin big sagebrush–native perennial grasslands

Ecosphere, Volume 11, Issue 5, May 2020., 2020
Abstract The structure and composition of sagebrush‐dominated ecosystems have been altered by changes in fire regimes, land use, invasive species, and climate change. This often decreases resilience to disturbance and degrades critical habitat for species of conservation concern. Basin big sagebrush (Artemisia tridentata ssp. tridentata) ecosystems, in

The native bee fauna of the Palouse Prairie (Hymenoptera: Apoidea) [PDF]

, 2017
While synoptic collections provide data on the range and general composition of the North American bee fauna, bee communities associated with specific habitats are largely uncharacterized.

Oviposition behavior and development of the invasive lily leaf beetle on native host plants from the Pacific Northwest United States

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1196-1204, November 2025.
This study examined the ability of the lily leaf beetle, Lilioceris lilii, to use native Liliaceae species as hosts in its newly invaded range in the Pacific Northwest, United States. We conducted oviposition and larval feeding trials with four lily species. Trials showed that L.

Flowering time evolution is independent of serpentine tolerance in the California flora

Ecosphere, Volume 8, Issue 4, April 2017., 2017
Abstract Comparative phylogenetic tests have been only recently applied to the many hypotheses about the role ultramafic (serpentine) soils play in the evolution and ecology of regional floras. An association between serpentine tolerance and early flowering has been observed at microevolutionary scales but not yet tested broadly across angiosperms.

A Phytogeographical Classification of the North American Pacific Coast Based on Climate, Vegetation and a Floristic Analysis of Vascular Plants

Journal of Botany, Volume 2009, Issue 1, 2009., 2009
This study was designed to explore floristic variation along the Pacific coast from Cook Inlet, Alaska, to the southern tip of Baja California, Mexico. Data corresponding to 965 phytosociological relevés (including 686 vascular plants) obtained by sampling 279 coastal sites were examined.

1154. Fritillaria of the Maritime Alps

Curtis's Botanical Magazine, Volume 42, Issue 3, Page 355-368, September 2025.
Summary The three taxa of the Fritillaria tubaeformis group are illustrated here. These plants are narrow endemic geophytes of the Alpine chain, where they are rare and representative of the subalpine grasslands, a very diverse and heterogeneous mosaic of habitats.
