Invasion-mediated mutualism disruption is evident across heterogeneous environmental conditions and varying invasion intensities Invasion-mediated mutualism disruption is evident across heterogeneous environmental conditions and varying invasion intensities
The impact of a biological invasion on native communities is expected to be uneven across invaded landscapes due to differences in local abiotic conditions, invader abundance, and traits and composition of the native community. One way to improve predictive ability about the impact of an invasive species given variable conditions is to exploit known mechanisms driving invasive species'...

Global responses to the COVID-19 pandemic by recreational anglers: Considerations for developing more resilient and sustainable fisheries Global responses to the COVID-19 pandemic by recreational anglers: Considerations for developing more resilient and sustainable fisheries
The global COVID-19 pandemic resulted in many jurisdictions implementing orders restricting the movements of people to inhibit virus transmission, with recreational angling often either not permitted or access to fisheries and/or related infrastructure being prevented. Following the lifting of restrictions, initial angler surveys and licence sales suggested increased participation and...

Reconstructing missing data by comparing interpolation techniques: Applications for long-term water quality data Reconstructing missing data by comparing interpolation techniques: Applications for long-term water quality data
Missing data are typical yet must be addressed for proper inferences or expanding datasets to guide our limnological understanding and management of aquatic systems. Interpolation methods (i.e., estimating missing values using known values within the dataset) can alleviate data gaps and common problems. We compared seven popular interpolation methods for predicting substantial...

Where can managers effectively resist climate-driven ecological transformation in pinyon-juniper woodlands of the US Southwest? Where can managers effectively resist climate-driven ecological transformation in pinyon-juniper woodlands of the US Southwest?
Pinyon–juniper (PJ) woodlands are an important component of dryland ecosystems across the US West and are potentially susceptible to ecological transformation. However, predicting woodland futures is complicated by species-specific strategies for persisting and reproducing under drought conditions, uncertainty in future climate, and limitations to inferring demographic rates from forest...

Larval cisco and lake whitefish exhibit high distributional overlap within nursery areas Larval cisco and lake whitefish exhibit high distributional overlap within nursery areas
Coregonine fishes, including lake whitefish (Coregonus clupeaformis) and cisco (C. artedi), are socioecologically important in the Laurentian Great Lakes and of conservation concern, but the processes driving recruitment variability are unclear. In Lake Ontario, cisco and lake whitefish exhibit similar spawning behaviours and early life histories, but population trajectories are...

Linking ecosystem processes to consumer growth rates: Gross primary productivity as a driver of freshwater fish somatic growth in a resource-limited river Linking ecosystem processes to consumer growth rates: Gross primary productivity as a driver of freshwater fish somatic growth in a resource-limited river
Individual growth can exert strong controls on population dynamics and be constrained by resource acquisition rates. Difficulty in accurately quantifying resource availability over large spatial extents and at high temporal frequency often limits attempts to understand the extent that resources limit individual growth. Daily estimates of stream metabolism, including gross primary...

Reproductive response of the Samoan swallowtail butterfly to variability in host plant and habitat characteristics Reproductive response of the Samoan swallowtail butterfly to variability in host plant and habitat characteristics
The Samoan swallowtail butterfly (Papilio godeffroyi) has become restricted to Tutuila Island, American Samoa. Factors driving its extirpation on other islands may be partly due to the availability and suitability of habitat, given the singular association we observed of P. godeffroyi with its host plant, Micromelum minutum. We expected that as a host plant specialist, P. godeffroyi...

Broadscale distribution, abundance and habitat associations of the invasive Asian clam (Corbicula fluminea) in the lower Columbia River, USA Broadscale distribution, abundance and habitat associations of the invasive Asian clam (Corbicula fluminea) in the lower Columbia River, USA
The Asian clam, Corbicula fluminea, is an invasive freshwater bivalve that has established populations across the globe and is known to have deleterious effects on natural and human systems. Yet, despite being present in the Columbia River (CR) for nearly a century, little is known about this invader's basic biology and ecology in this large river system. Thus, we undertook a field study...

When are environmental DNA early detections of invasive species actionable? When are environmental DNA early detections of invasive species actionable?
Environmental DNA (eDNA) sampling provides sensitive early detection capabilities for recently introduced taxa. However, natural resource managers struggle with how to integrate eDNA results into an early detection rapid response program because positive eDNA detections are not always indicative of an eventual infestation. We used a structured decision making (SDM) framework to evaluate

Susceptibility of Pallid Sturgeon to viral hemorrhagic septicemia virus genotype IVb Susceptibility of Pallid Sturgeon to viral hemorrhagic septicemia virus genotype IVb
Objective Viral hemorrhagic septicemia virus (VHSV) is an aquatic rhabdovirus causing severe disease in freshwater and saltwater fish species. The susceptibility of endangered Pallid Sturgeon Scaphirhynchus albus to VHSV genotype IVb (VHSV-IVb) infection was investigated.Methods An in vitro assessment using two Pallid Sturgeon cell lines derived from skin and spleen tissue and in vivo...

A retrospective assessment of fuel break effectiveness for containing rangeland wildfires in the sagebrush biome A retrospective assessment of fuel break effectiveness for containing rangeland wildfires in the sagebrush biome
Escalated wildfire activity within the western U.S. has widespread societal impacts and long-term consequences for the imperiled sagebrush (Artemisia spp.) biome. Shifts from historical fire regimes and the interplay between frequent disturbance and invasive annual grasses may initiate permanent state transitions as wildfire frequency outpaces sagebrush communities’ innate capacity to...

Elevated road segment (ERS) passage design may provide enhanced connectivity for amphibians, reptiles, and small mammals Elevated road segment (ERS) passage design may provide enhanced connectivity for amphibians, reptiles, and small mammals
Introduction: Designs for safe and effective road crossing structures for small animals are typically under-road microtunnels and culverts which have varying levels of effectiveness reported in the scientific literature. Many species, particularly migratory amphibians, may have limited ability to find and use passages if they are too far apart, resulting in substantial barrier effects...
