Transcriptional changes in wild Yukon River Chinook Salmon associated with Ichthyophonus infections Transcriptional changes in wild Yukon River Chinook Salmon associated with Ichthyophonus infections
Objective We compared differentially expressed genes in Chinook Salmon Oncorhynchus tshawytscha with three divergent Ichthyophonus statuses (undetected, subclinical infections, or clinical disease; n = 100) to investigate associated transcriptomic responses. Disease associated with the fish parasite Ichthyophonus sp. was first diagnosed in adult Chinook Salmon from the Yukon River in the...

Transit time modeling framework for predicting freshwater salinization in urban catchments Transit time modeling framework for predicting freshwater salinization in urban catchments
The salinity of inland freshwaters is rising globally, particularly in urban watersheds where winter road deicers are widely applied. Attributing stream salinity dynamics to specific sources and transport pathways remains challenging due to episodic salt inputs, engineered drainage, and strong coupling between hydrology and subsurface storage. We present a modeling framework that couples...

Trends in subdaily to daily rainfall in Florida, 1990–2022 Trends in subdaily to daily rainfall in Florida, 1990–2022
Changing rainfall patterns and intensifying rainfall extremes affect urban infrastructure and can increase flash-flood risk. Understanding how climate change has altered rainfall can support state and local agencies as they adapt and build resiliency. In this study, rainfall data from 23 weather stations in Florida were used to examine temporal and spatial trends over the period 1990...

Tringa flavipes (Lesser Yellowlegs) from separate breeding sites subdivides the Prairie Pothole Region in space and time during southbound migration Tringa flavipes (Lesser Yellowlegs) from separate breeding sites subdivides the Prairie Pothole Region in space and time during southbound migration
Some staging regions support multiple groups of the same migratory species, each of which may use the region differently. Characterizing the ways, in which separate groups use such regions can therefore help to identify vulnerabilities during this sensitive period of the annual cycle. The Prairie Pothole Region (PPR) is a massive wetland complex in the northern Great Plains of North...

Triple oxygen isotope compositions of isotopic reference waters: Implications for VSMOW-Scale and VSMOW-SLAP-Scale Δ′¹⁷O calibration Triple oxygen isotope compositions of isotopic reference waters: Implications for VSMOW-Scale and VSMOW-SLAP-Scale Δ′¹⁷O calibration
Triple oxygen isotope ratios of waters are commonly reported on the VSMOW–SLAP scale, whereas comparison with theoretical calculations and assessment of instrumental scale distortion require accurate constraints on the measured isotopic compositions of the primary isotopic reference materials (iRMs) themselves. In particular, the measured δ17OVSMOW and Δ′17OVSMOW values for SLAP and its...

Tropical and subtropical coral reefs Tropical and subtropical coral reefs
Global declines in coral cover persist, owing to increasing ocean temperatures associated with climate change, continued coastal development, pollution, sedimentation, diseases and the destruction and overextraction of marine resources (through fishing and coral harvesting). These stressors have an impact on coral biodiversity, reef-associated fauna and the architectural complexity of...

Tropicalization of the temperate zone: Spatiotemporal variability of winter warming and declining freeze days across the United States Tropicalization of the temperate zone: Spatiotemporal variability of winter warming and declining freeze days across the United States
We investigate changes in cool-season and winter daily minimum (Tmin) and maximum (Tmax) temperatures, and the occurrence of freeze days, from 1952 to 2024 across the conterminous United States (CONUS). Emphasis is placed on the tropical-temperate transition zone (TTTz) in the southeastern CONUS. During winter, ~70% of the land area exhibited Tmin warming rates exceeding those of Tmax...

Trust-building as a keystone activity in beaver-related restoration practice Trust-building as a keystone activity in beaver-related restoration practice
North American beavers (Castor canadensis) are increasingly being used to achieve restoration goals, prompting practitioners to engage with private landowners in efforts to promote beaver coexistence. Through 23 semi-structured interviews with restoration practitioners in Oregon, USA, we explored how practitioners from government agencies, non-governmental organizations (NGOs), service

Two hundred years of historical spawning and nursery data for coregonine fishes in the Laurentian Great Lakes Two hundred years of historical spawning and nursery data for coregonine fishes in the Laurentian Great Lakes
Historical data can provide critical ecological information for species across the globe, many of which are facing unprecedented rates of ecosystem change. Yet, historical information related to freshwater species, especially fishes, remains scattered, often in original formats, and underutilized for informing conservation and restoration activities. Here, we present a Data Descriptor...

Two-stage approach to automatic detection with machine learning for improved surveillance of the invasive Cuban treefrog Two-stage approach to automatic detection with machine learning for improved surveillance of the invasive Cuban treefrog
The Cuban treefrog (Osteopilus septentrionalis), as an invasive species in the southern United States, presents a need for effective surveillance. Automated detection expedites processing of audio data for large-scale surveillance and monitoring programs. However, current available methods commonly used for anuran species have not been sufficient to detect Cuban treefrogs. Here, we...
