Post-fire recovery of sagebrush-steppe communities is better explained by elevation than climate-derived indicators of resistance and resilience Post-fire recovery of sagebrush-steppe communities is better explained by elevation than climate-derived indicators of resistance and resilience
More landscapes require restoration than can feasibly be treated, and so decision-support tools to prioritize areas for treatment are needed. Moreover, restoration is complicated by the threat of biological invasion in disturbed areas, and so indicators of ecosystem resistance to invasion and resilience to disturbance (hereafter R&R) are important candidate criteria for prioritizing...

A case for assemblage-level conservation to address the biodiversity crisis A case for assemblage-level conservation to address the biodiversity crisis
Traditional conservation efforts have centred on safeguarding individual species, but these strategies have limitations in a world where entire ecosystems are rapidly changing. Ecosystem conservation can maintain critical ecological functions, but often lacks the detail necessary for the effective conservation of threatened or endangered species. The conservation of such species is...

Population genomics reveals local adaptation related to temperature variation in two stream frog species: Implications for vulnerability to climate warming Population genomics reveals local adaptation related to temperature variation in two stream frog species: Implications for vulnerability to climate warming
Identifying populations at highest risk from climate change is a critical component of conservation efforts. However, vulnerability assessments are usually applied at the species level, even though intraspecific variation in exposure, sensitivity and adaptive capacity play a crucial role in determining vulnerability. Genomic data can inform intraspecific vulnerability by identifying...

Considering multiecosystem trade-offs is critical when leveraging systematic conservation planning for restoration Considering multiecosystem trade-offs is critical when leveraging systematic conservation planning for restoration
Conservationists are increasingly leveraging systematic conservation planning (SCP) to inform restoration actions that enhance biodiversity. However, restoration frequently drives ecological transformations at local scales, potentially resulting in trade-offs among wildlife species and communities. The Conservation Interactions Principle (CIP), coined more than 15 years ago, cautions SCP

Jaguar density estimation in Mexico: The conservation importance of considering home range orientation in spatial capture–recapture Jaguar density estimation in Mexico: The conservation importance of considering home range orientation in spatial capture–recapture
Accurate estimation of population parameters for imperiled wildlife is crucial for effective conservation decision-making. Population density is commonly used for monitoring imperiled species across space and time, and spatial capture–recapture (SCR) models can produce unbiased density estimates. However, many imperiled species are restricted to fragmented remnant habitats in landscapes...

Forecasting water levels using the ConvLSTM algorithm in the Everglades, USA Forecasting water levels using the ConvLSTM algorithm in the Everglades, USA
Forecasting water levels in complex ecosystems like wetlands can support effective water resource management, ecological conservation, and understanding surface and groundwater hydrology. Predictive models can be used to simulate the complex interactions among natural processes, hydrometeorological factors, and human activities. The Greater Everglades in the USA is a well-known example...

Developing biocrust field cultivation techniques for soil restoration: An assessment of bacterial communities Developing biocrust field cultivation techniques for soil restoration: An assessment of bacterial communities
Biological soil crusts (biocrusts) are a coherent, thin soil surface layer, engineered and inhabited by a diverse community of moss, lichen, cyanobacteria, and other microorganisms. Biocrusts provide critical functions in dryland systems and may be lost from the ecosystem through physical disturbance or other global change drivers. Once biocrusts are lost, natural recovery can occur very...

Ecosystem drivers of freshwater mercury bioaccumulation are context-dependent: Insights from continental-scale modeling Ecosystem drivers of freshwater mercury bioaccumulation are context-dependent: Insights from continental-scale modeling
Significant variation in mercury (Hg) bioaccumulation is observed across the diversity of freshwater ecosystems in North America. While there is support for the major drivers of Hg bioaccumulation, the relative influence of different external factors can vary widely among waterbodies, which makes predicting Hg risk across large spatial scales particularly challenging. We modeled Hg...

A Colorado Front Range grassland exhibits decreasing dominance of cheatgrass (Bromus tectorum) over time A Colorado Front Range grassland exhibits decreasing dominance of cheatgrass (Bromus tectorum) over time
Causes, consequences, and potentials for recovery from invasions by the invasive annual grass, cheatgrass (Bromus tectorum), in western North America have been extensively documented. The vast majority of these studies have come from regions where yearly precipitation is dominated by “winter-wet” patterns, but this species has also demonstrated its ability to invade plant communities in...

Bayesian model selection to investigate meaningful spatial scales Bayesian model selection to investigate meaningful spatial scales
Ecologists and other statistical practitioners with access to high-resolution spatial data lack guidance on best approaches for discerning meaningful spatial scales for environmental covariates which is necessary when spatial factors influence environmental processes. Recently developed methods have attempted to automate investigating spatial scales for covariates by evaluating models...

An enigmatic wild passerine mortality event in the eastern United States An enigmatic wild passerine mortality event in the eastern United States
The ability to rapidly respond to wildlife health events is essential. However, such events are often unpredictable, especially with anthropogenic disturbances and climate-related environmental changes driving unforeseen threats. Many events also are short-lived and go undocumented, making it difficult to draw on lessons learned from past investigations. We report on the response to a...

Understanding and predicting infection dynamics for an endangered amphibian using long-term surveys of wild and translocated frogs Understanding and predicting infection dynamics for an endangered amphibian using long-term surveys of wild and translocated frogs
Amphibians are a prominent component of Earth's sixth mass extinction and the fungal pathogen Batrachochytrium dendrobatidis (Bd) is a primary driver of declines. Although Bd dynamics are well studied, the environmental drivers, exacerbating risk factors, and value of conservation interventions like translocations remain challenging to predict. Here, we present results from two decades...
