Using Aerial LiDAR Data to Map Vegetation Structural Types in Arid and Semi-Arid Rangelands

open access: yesRemote Sensing
Rangelands occupy over half of the Earth’s terrestrial surface and play an important role in supporting biodiversity and livelihoods. However, widespread degradation—particularly in arid and semi-arid regions—has compromised their ecological function ...

Integrated species distribution modeling to assess species status and current and future threats for an imperiled amphibian

open access: yesConservation Science and Practice, EarlyView.
To understand the range‐wide drivers of Arizona Toad distribution and anticipate future changes, we combined 13 datasets covering distinct portions of the range in an integrated species distribution model. We estimate that the current occupied range is 1/4–1/3 of previously defined range boundaries and that increasingly dry conditions will lead to ...

Pro‐environment behaviors, invasive plant management, and the gap between motivations for behavioral intention and action

open access: yesConservation Science and Practice, EarlyView.
Invasive plant species pose significant challenges to natural resources and communities around the world. However, invasive plant management may require different motivations than other pro‐environmental behaviors because mitigation of invasive plants often comes at high individual cost, has limited effectiveness when undertaken in isolation, and ...

Tolerance for jaguars among ranching communities in the Colombian Llanos

open access: yesConservation Science and Practice, EarlyView.
Livestock protection measures are often implemented with the desired outcome of reducing retaliatory killings. We studied drivers of retaliatory killings in four communities in the Colombian Llanos and evaluated whether an electric fencing intervention would improve tolerance for jaguars.

Threat Integration Model for Sagebrush (TIMS): A framework for using spatial decision support tools for strategic management of invasive annual grasses and conifers in sagebrush ecosystems

open access: yesConservation Science and Practice, EarlyView.
The Threat Integration Model for Sagebrush (TIMS) combines multiple spatial decision support tools to provide a unified, actionable map of sagebrush ecosystem conditions across the western United States. TIMS improves upon existing tools by including multiple threats in the same map (invasive annual grass [IAG] and conifer encroachment), characterizing

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

open access: yesGroundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

Environmental and seasonal filtering of taxonomic, functional and phylogenetic diversity patterns of mountain butterflies in a prime butterfly area, Greece

open access: yesInsect Conservation and Diversity, EarlyView.
Forest clearings support butterfly communities comparable to mountainous grasslands in alpha‐diversity and conservation value, yet remain compositionally distinct. Generalized linear models (GLMs) showed three key habitat predictors shaping multifaceted diversity and community composition: herb/grass height, flowerhead abundance and elevation.

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Application of Normalized Radar Backscatter and Hyperspectral Data to Augment Rangeland Vegetation Fractional Classification

open access: yesRemote Sensing
Rangeland ecosystems in the western United States are vulnerable to climate change, fire, and anthropogenic disturbances, yet classification of rangeland areas remains difficult due to frequently sparse vegetation canopies that increase the influence of ...
