Climatic drought and trophic disruption in an endemic subalpine Hawaiian forest bird Climatic drought and trophic disruption in an endemic subalpine Hawaiian forest bird
Overexploitation, habitat conversion, and introduced species have caused unprecedented extinctions and heavily degraded native bird populations in island ecosystems. In the Hawaiian Islands, stemming these losses has proven difficult as the highly specialized avifauna are often impacted – among other things – by poorly understood trophic disruptions as well as persistent climatic shifts...

Predicted occurrence of Eastern Newts (Notophthalmus viridescens viridescens) across the northeastern United States Predicted occurrence of Eastern Newts (Notophthalmus viridescens viridescens) across the northeastern United States
Effective conservation is becoming more difficult as threats to wildlife increase. Natural resource managers are pressured to make difficult decisions with limited resources, and in many instances, large uncertainty. Scientists and managers tasked with the conservation of a species need tools to help guide efficient decision-making. Often, information for management decisions is...

Rappahannock tributary summary: A summary of trends in tidal water quality and associated factors, 1985-2022 Rappahannock tributary summary: A summary of trends in tidal water quality and associated factors, 1985-2022
The Rappahannock Tributary Summary outlines change over time for a suite of monitored tidal water quality parameters and associated potential drivers of those trends for the period of 1985 to 2022, and provides a brief description of the current state of knowledge explaining these observed changes. Water quality parameters described include surface (above pycnocline) total nitrogen (TN)...

Edge effects along roadside fuel treatments in sagebrush steppe Edge effects along roadside fuel treatments in sagebrush steppe
Increasing wildfire has motivated the construction of fuel breaks on many rangelands to improve prospects for wildfire suppression. However, the linear shape of fuel breaks greatly increases treatment perimeter: area and thus increased potential for edge effects, e.g., invasions by exotic plants. Potential for edge effects are further increased by the disturbances associated with fuel...

From causes of conflict to solutions: Shifting the lens on human–carnivore coexistence research From causes of conflict to solutions: Shifting the lens on human–carnivore coexistence research
Human-carnivore conflicts pose significant challenges in the management and conservation of carnivores across the globe. Abundant research has led to generalizable insights into the causes of such conflicts. For example, conflicts predictably occur when carnivores have access to human food resources, particularly when their natural foods are scarce. However, similar insights into the...

Correction to A regime shift in sediment export from a coastal watershed during a record wet winter, California: Implications for landscape response to hydroclimatic extremes Correction to A regime shift in sediment export from a coastal watershed during a record wet winter, California: Implications for landscape response to hydroclimatic extremes
In the referenced article, the authors would like to correct text in the first paragraph on page 2571, Figure 9 and its caption. The changes reflect an error made in the processing of the rainfall intensity-duration data used to compare storms to published debris flow triggering thresholds. The correctly processed data does not change the interpretations made in the paper but does...

White-backed hog-nosed skunk (Conepatus Leuconotus) occurrence in the Oklahoma panhandle White-backed hog-nosed skunk (Conepatus Leuconotus) occurrence in the Oklahoma panhandle
The white-backed hog-nosed skunk (Conepatus leuconotus) is an understudied mesocarnivore thought to be declining throughout its range in the southwestern United States. With the exception of a single skull of unknown age, hog-nosed skunks have not been documented in Oklahoma since 1930. We conducted a camera trapping survey in Cimarron County, Oklahoma during summer 2022 and confirmed...

Evaluating hydrologic model performance for characterizing streamflow drought in the conterminous United States Evaluating hydrologic model performance for characterizing streamflow drought in the conterminous United States
Hydrologic models are the primary tools that are used to simulate streamflow drought and assess impacts. However, there is little consensus about how to evaluate the performance of these models, especially as hydrologic modeling moves toward larger spatial domains. This paper presents a comprehensive multi-objective approach to systematically evaluating the critical features in...

Transfer learning with convolutional neural networks for hydrological streamline delineation Transfer learning with convolutional neural networks for hydrological streamline delineation
Hydrological streamline delineation is critical for effective environmental management, influencing agriculture sustainability, river dynamics, watershed planning, and more. This study develops a novel approach to combining transfer learning with convolutional neural networks that capitalize on image-based pre-trained models to improve the accuracy and transferability of streamline...

The potential for species distribution models to distinguish source populations from sinks The potential for species distribution models to distinguish source populations from sinks
1. While species distribution models (SDM) are frequently used to predict species occurrences to help inform conservation management, there is limited evidence evaluating whether habitat suitability can reliably predict intrinsic growth rates or distinguish source from sink populations. Filling this knowledge gap is critical for conservation science, as applications of SDMs for...

No evidence hunting bait increases American black bear population growth in Maine, USA No evidence hunting bait increases American black bear population growth in Maine, USA
American black bear (Ursus americanus) populations are increasing throughout much of North America. Use of multiple harvest methods, including hunting over bait, is intended to increase harvest success rates to meet harvest and population management objectives. However, black bear population growth can be influenced by food availability, and some speculate the use of bait may...
