A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Projected Temperature and Precipitation Expand Modeled Distributions of Reynoutria spp. While Modeled Distribution Changes for Ludwigia spp. Are Scenario‐Dependent at Watershed Scales in the Pacific Northwest, USA

River Research and Applications, EarlyView.
ABSTRACT Invasive species can fundamentally alter their introduced habitats by changing natural processes and harming native species crucial to functional ecosystems and human needs. Although the number of potential invasive species is large, the suitability of novel locations to support population establishment is limited by both physical and ...

Rapid high-latitude cooling in the southeastern Pacific sector driven by North Atlantic warming during 1979–2013 in CESM1

Environmental Research Letters
During the 1979–2013 satellite observation period, the sea surface temperature (SST) has cooled substantially in the high-latitude Southern Ocean, with the most pronounced cooling tendency centered in the southeastern Pacific domain.

Big Bird: A global dataset of birds in drone imagery annotated to species level

Remote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Late Pliocene calcareous nannofossil paleobiogeography of the Pacific Ocean: evidence for glaciation at 2.75 Ma

Revista Mexicana de Ciencias Geológicas, 2018
Calcareous nannofossil assemblages from land sections of the Japanese Islands and DSDP Holes in the equatorial to high latitude regions of the Pacific Ocean were analyzed in an effort to reconstruct their late Pliocene paleobiogeography.

Climate‐Driven Mangrove Dieback and Recovery: A Case Study in Albert and Leichhardt Rivers, Australia

Remote Sensing in Ecology and Conservation, EarlyView.
Cycles of dieback and recovery drove mangrove forest dynamics at the Albert and Leichhardt Rivers (Gulf of Carpentaria, Queensland, Australia) over 36 years (1987–2023). Landward margins were the most affected by reduced tidal inundation when the alignment of low lunar declination suppressed tidal range and extreme El Niño phases lowered mean sea level.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.
