Changes in Spatial Distribution and Abundance Together Determine Potential for Population Persistence for Greater Sage‐Grouse

Diversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Population ecologists often focus on changes in the distribution and abundance of wildlife species, which are useful for trend analyses and status assessments. However, rarely are these responses evaluated simultaneously for a single species, despite their unique contributions to fully assess a species' viability.

Phytotoxic Activity of Metabolites Isolated from Rutstroemia sp.n., the Causal Agent of Bleach Blonde Syndrome on Cheatgrass (Bromus tectorum)

Molecules, 2018
A fungal pathogen soon to be described as Rutstroemia capillus-albis (Rutstroemiaceae, Helotiales, Leotiomycetes) has been identified as the causal agent of ‘bleach blonde syndrome’ on the invasive annual grass weed Bromus tectorum ...

Modeling Phenotypic Trait Variation and Plasticity in Elymus elymoides to Guide Climate‐Informed Seed Transfer

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Information on climate‐associated phenotypic variation is essential for sourcing seed that matches restoration site conditions. Spatially explicit seed transfer models can effectively deliver this information. However, standard modeling approaches often do not provide flexibility for practical considerations and may not capture highly complex ...

Seed transfer models applied to commercial germplasms reveal trait divergence from wildland populations of a restoration grass species

Restoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Due to the prevalence of local adaptation in plants, the provenance of seed sources can impact plant community restoration outcomes. Yet programs developing commercial germplasm releases often overlook local adaptation as a development criterion, leading to the selection of traits that may not support restoration success.

Factors Affecting Bromus Tectorum Seed Bank Carryover in Western Utah [PDF]

Rangeland Ecology & Management, 2008
Cheatgrass (Bromus tectorum L.) is a winter annual weed that presents a serious obstacle to rangeland restoration in the Intermountain West. The objective of this study was to evaluate factors regulating the size and persistence of cheatgrass carryover seed banks on semiarid sites in western Utah.

Seed pretreatment length when producing seeds for restoration may impact seed dormancy in offspring

Restoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Seed dormancy regulates germination timing to improve seedling survival. Many temperate species produce physiologically dormant seeds, requiring winter conditions (i.e. moist‐cold stratification) to overcome dormancy. Exposing seeds to suboptimal stratification lengths for restoration may alter genetic diversity and/or ...

Predictive model for soil seedbank outcomes in the Pyrenophora semeniperda-Bromus tectorum pathosystem

Plant Protection Science, 2013
Pyrenophora semeniperda is abundant in soil seed banks of Bromus tectorum, where it kills a fraction of seeds throughout the year. The pathogen engages in a race with host seeds for endosperm resources; the pathogen success is negatively correlated with ...

Mixed effects of drought on species‐level traits and plant composition in the United States mixed‐grass prairie

Journal of Ecology, Volume 114, Issue 2, February 2026.
Plant communities in two working rangeland mixed‐grass prairies were tolerant of implemented drought. However, plant functional traits within individual species shifted towards those that indicate drought avoidance and tolerance when rainfall was limited. One site and three traits shown for brevity. To understand how ecosystems like mixed‐grass prairie

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...
