Effects of invasive plants on fire regimes and postfire vegetation diversity in an arid ecosystem

Ecology and Evolution, 2019
We assessed the impacts of co‐occurring invasive plant species on fire regimes and postfire native communities in the Mojave Desert, western USA. We analyzed the distribution and co‐occurrence patterns of three invasive annual grasses (Bromus rubens ...

A matter of timing: sagebrush steppe restoration seeding outcomes altered by species responses to warmer spring temperatures and interannual weather variation

Restoration Ecology, EarlyView.
Abstract Introduction Restoration outcomes in cold desert ecosystems like sagebrush steppe are affected by weather variability, particularly during the spring, a critical time period for seedling establishment. Seedling emergence phenology is also highly variable among species in these ecosystems.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Rapid Surveys Reveal Temporal Variation in Flowering Community Phenology in a Great Basin Desert Ecosystem

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Across four years of surveys in an arid Great Basin ecosystem, community flowering phenology showed strong seasonal, interannual, and trait‐based variation, with most differences occurring in spring and little variation in fall. Flowering patterns broadly corresponded with interannual climate variability, consistent with the importance of moisture ...

Mechanisms controlling the distribution of two invasive Bromus species

Frontiers of Biogeography, 2014
In order to predict future range shifts for invasive species it is important to explore their ability to acclimate to the new environment and understand physiological and reproductive constraints controlling their distribution.

Subgenomic Distribution and Herbicide Cross‐Resistance of ALS Gene Mutations in Allohexaploid Echinochloa crus‐galli

Plant Direct, Volume 10, Issue 4, April 2026.
ABSTRACT Herbicide target site resistance in polyploid species is more complex than in diploids due to potential subgenome interactions. This study characterized mutations in the ALS gene across distinct subgenomes of hexaploid Echinochloa crus‐galli and evaluated the cross‐resistance patterns conferred by each mutation to various ALS‐inhibiting ...

The role of inoculum dispersal and plant species identity in the assembly of leaf endophytic fungal communities.

PLoS ONE, 2019
Because of disturbance and plant species loss at the local level, many arid ecosystems in the western USA benefit from revegetation. There is a growing interest in improving revegetation success by purposefully inoculating revegetation plants with ...

De novo genome assembly of the fungal plant pathogen Pyrenophora semeniperda. [PDF]

PLoS ONE, 2014
Pyrenophora semeniperda (anamorph Drechslera campulata) is a necrotrophic fungal seed pathogen that has a wide host range within the Poaceae. One of its hosts is cheatgrass (Bromus tectorum), a species exotic to the United States that has invaded natural

Novel Approaches to Invasive Annual Grass Management: Assessing Efficacy and Impacts on Target Species and Plant Diversity

Applied Vegetation Science, Volume 29, Issue 2, April/June 2026.
Understanding how target weeds and surrounding plant communities respond to traditional and novel management is essential to meeting agricultural sustainability goals. We monitored target species cover (Bromus tectorum) and plant community diversity for 3 years following management.

Detecting Pteridium arachnoideum and Tithonia diversifolia in a Multiclass Land‐Cover Framework in the Cerrado: A Deep Learning Time‐Series Benchmark With Spatial Cross‐Validation

Transactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT This study presents the first deep‐learning time‐series benchmark for detecting two encroaching species in the Brazilian Cerrado: the native super‐dominant fern Pteridium arachnoideum and the invasive alien shrub Tithonia diversifolia. We evaluate 43 architectures across six families (CNNs, RNNs, Transformers, and three hybrid groups) on ...
