This data release contains two sets (reflective and dissipative) of synthesized barred beach profiles based on conditions in the University of New South Wales Water Research Laboratory's 0.9-meter wave flume. The profiles were collected using the methods outlined in Conti and others (2024) and then synthesized using the functions and relationships described by Stephens and others (2010)...

The Santa Ana Sucker (Pantosteus santaanae) is a federally threatened species endemic to the Santa Ana, San Gabriel, and Los Angeles Rivers in southern California. Seasonal limitations on conventional sampling and inconsistencies in survey methodologies have led to an incomplete understanding of Santa Ana Sucker population dynamics. Therefore, alternative sampling methods that are not...

This data release includes relative landslide hazard estimate maps for the southern Appa­lachian Mountains affected by Hurricane Helene (September 26-27, 2024) and the heavy rainfall that preceded it (September 23-26, 2024). The two modeling approaches used were adapted from existing models and were run in early October 2024 using initial precipitation estimates to produce rapid event...

Reports of negative interactions between humans and bears in Maryland have increased steadily since the 1990s, requiring substantial investments of time and resources for their management. While managers typically possess a strong understanding of the spatial distribution of current and historical interactions, they lack the quantitative tools necessary to predict where future...

We provide fractional cover estimates for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from mid-April to late June 2025. The cover estimates reflect actual conditions of the previous week and are released in an expedited manner, within 7-13 days of the latest satellite observation used for that weekly prediction. Each weekly release contains...

Comma-separated values (.csv) file containing data related to the 2016 International Piping Plover Breeding Census.

This dataset includes global rasters of terrestrial biological nitrogen fixation (BNF) rates (in kg N/ha/y) for each major N-fixing niche in natural biomes (trees, shrubs, herbs, soil, litter, dead wood, ground mosses, biocrusts, and epiphytic lichens) and agricultural biomes (legume crops, forage legumes, and rice). It also includes total natural terrestrial, total agricultural, and...

This dataset includes field measurements of biological nitrogen fixation (BNF) in all major N-fixing niches across natural terrestrial biomes globally. The dataset comprises 32 variables including site location, biome type, N-fixing niche, sampling year, quantification method, BNF rate (in kg N/ha/y), the percentage of nitrogen derived from the atmosphere, N-fixer or N-fixing substrate...

In 2023, critically endangered California condors experienced an outbreak of highly pathogenic avian influenza (HPAI). We evaluated safety, immunogenicity, vaccination strategies, and correlates of antibody response of a conditionally licensed influenza vaccine for poultry in black vultures and then California condors. These data represent the correlates of antibody response, including

This dataset contains environmental DNA (eDNA) data (field, extraction, and qPCR) for rainbow trout sampling efforts conducted in the Pacific Northwest in 2019. Samples were collected using three eDNA sampling methods. Also included are qPCR data for extraction negatives, no-template controls (NTC), and standard dilutions of rainbow trout gBlock. NTC and gBlock qPCR data were used to...

This data release contains geospatial representations of population viability analysis (PVA) of 23 species of Pacific Northwest non-salmonid fishes. The analysis evaluated long term species persistence (~100 years) based on species distribution models that combined 1) modeled climate, 2) instream conditions, and 3) presence/absence fish data based on species needs and current climate...

This data release provides spatial data for species distribution models developed for 24 stream fishes native to the Pacific Northwest, USA and associated model evaluation metrics used to determine the best supported model. These models support a larger analysis for understanding native stream fish vulnerability in the region, specifically population viability analyses built to determine...
