Evaluating seedling traits, maintenance and effective costs to support tropical forest restoration practices Evaluating seedling traits, maintenance and effective costs to support tropical forest restoration practices
While large-scale restoration is essential, tropical forest restoration often depends on small-scale practitioners and landowners who produce, plant and maintain trees. Their collective impact on restoring forest diversity and function is substantial, making it critical to address the constraints they face through efficient, effective techniques.We used generalized linear mixed models to...

Cognitive and institutional barriers to effective natural resource management under global change Cognitive and institutional barriers to effective natural resource management under global change
Many of the most challenging decisions facing natural resource managers today can be understood as time dependent. The concept of time-dependent decisions is useful when considering natural resource management decisions that are characterized by nonstationarity in the underlying ecological system, uncertainty surrounding key ecological relationships, efficacy of management interventions...

Mountain lion prey-selection in a community comprised of native and introduced ungulate species Mountain lion prey-selection in a community comprised of native and introduced ungulate species
Species introductions are a hallmark of human influence on ecosystems worldwide. In communities where native and introduced fauna coexist, predators may select prey based on availability or vulnerability. Free-roaming feral horses (Equus caballus) are a recent addition to North America and have become widespread, abundant, and in some areas serve as major prey for mountain lions (Puma...

Updates to the Lake Washington Ship Canal and Ballard Locks model, Seattle, Washington, 2016–20 Updates to the Lake Washington Ship Canal and Ballard Locks model, Seattle, Washington, 2016–20
The Hiram M. Chittenden Locks (Ballard Locks or Locks) and Lake Washington Ship Canal connect freshwater Lake Washington with saline Shilshole Bay of Puget Sound. The Locks are operated by the U.S. Army Corps of Engineers (USACE) and serve commercial and recreational vessels. Anadromous salmonids migrate through the canal by making use of a fish ladder at the Locks. To help understand...

Water depth fluctuations and water chemistry in five ephemeral rock pools (tinajas), Clark County, Nevada, 2021–23 Water depth fluctuations and water chemistry in five ephemeral rock pools (tinajas), Clark County, Nevada, 2021–23
Southern Nevada is characterized by an arid climate with limited perennial water resources. In this environment, rock pools (tinajas) are both a habitat and drinking water source for wildlife. In this reconnaissance-level project, the U.S. Geological Survey studied the water depth and water chemistry at five tinajas in Clark County, Nevada. The tinaja sites in this study are...

An extensive and short-lived episode of mid-Holocene fayalite- bearing high-silica rhyolite eruptions at Mono Craters, California An extensive and short-lived episode of mid-Holocene fayalite- bearing high-silica rhyolite eruptions at Mono Craters, California
Having last erupted ~ 700 years ago, the Mono Craters volcanic chain is an active system with a history of explosive and effusive high-silica rhyolite eruptions. Approximately ~ 30 lava domes and flows range from ~ 42 to ~ 0.7 ka, form a ~ 15 km curvilinear trend, and change mineralogy (biotite-, orthopyroxene-, or fayalite-bearing) and crystallinity through time. However, the eruptive...

A multi-state assessment of per- and polyfluoroalkyl substances (PFAS), pesticides, and antibiotic resistance genes in white-tailed deer (Odocoileus virginianus) of the United States A multi-state assessment of per- and polyfluoroalkyl substances (PFAS), pesticides, and antibiotic resistance genes in white-tailed deer (Odocoileus virginianus) of the United States
Sentinel species provide a vital One Health perspective on ecosystem contamination driven by rising global chemical production. We evaluated white-tailed deer (Odocoileus virginianus; n = 54, 24 states, six matrices) as nationwide bioindicators for PFAS, pesticides, antimicrobial resistance (AMR) genes, and microbiome diversity. PFAS were detected in 100% of deer samples (26 compounds...

Springs of the Catskill Mountains: A conduit flow system in predominantly siliciclastic strata Springs of the Catskill Mountains: A conduit flow system in predominantly siliciclastic strata
The Catskill Mountains of New York state are composed of thick sequences of interbedded mudstone, sandstone, and siltstone that are intercalated with thin beds of paludal limestone and calcareous mudstone. Sandstones often contain rip-up clasts of calcareous material at their bases and contain minor amounts of carbonate cement throughout their mass. This minor amount of calcareous...
