The road less taken: Dihydroflavonol 4-reductase inactivation and delphinidin anthocyanin loss underpins a natural intraspecific flower colour variation. [PDF]

open access: yesMol Ecol
Abstract Visual cues are of critical importance for the attraction of animal pollinators, however, little is known about the molecular mechanisms underpinning intraspecific floral colour variation. Here, we combined comparative spectral analysis, targeted metabolite profiling, multi‐tissue transcriptomics, differential gene expression, sequence ...

Do Snow-Adapted Prey Facilitate Coexistence of the Sierra Nevada Red Fox With Sympatric Carnivores? [PDF]

open access: yesMol Ecol
ABSTRACT Specialist species in alpine ecosystems may be increasingly threatened by climate‐driven habitat loss and encroachment by generalist competitors. Ecological theory predicts that niche differentiation through dietary specialisation can facilitate coexistence with generalist competitors.

Social but not solitary bee abundance tracks pollen protein accumulation in forest canopy gaps

open access: yesEcological Entomology, Volume 48, Issue 6, Page 738-754, December 2023., 2023
Based on ~6500 interactions in canopy gap habitats, bee foraging periods strongly overlapped with floral protein density in large‐bodied, social and aboveground nesting bees, but not in bees of other functional groups. Bee abundance is predicted by nutritional availability.

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

open access: yesConservation 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

open access: yesEcology 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

open access: yesEcosphere, 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

Data from: Spatial scales of genetic structure and gene flow in Calochortus albus (Liliaceae)

open access: yes, 2013
Calochortus (Liliaceae) displays high species richness, restriction of many individual taxa to narrow ranges, geographic coherence of individual clades, and parallel adaptive radiations in different regions.

The Effect of Smoke-Water on Seed Germination of 18 Grassland Plant Species

open access: yesFire
There is an urgent and constant need for land reclamation and to restore self-sustaining, stable, and resilient ecosystems. It is necessary to enhance the frequency, consistency, and success rates of applying native plant seed for ecological restoration.
