In vitro impacts of glyphosate on manatee lymphocytes In vitro impacts of glyphosate on manatee lymphocytes
Exposure to contaminants, such as the herbicide glyphosate, can suppress protective immune functions. Glyphosate is the herbicide most used worldwide and has been found in the plasma of more than 50 % of the Florida manatees (Trichechus manatus latirostris) and all-year-round in their aquatic environment. Our objectives were to analyze the consequences of glyphosate exposure on their...

Assessing mosquito populations to limit the spread of avian disease and inform the conservation of Hawaiian forest birds Assessing mosquito populations to limit the spread of avian disease and inform the conservation of Hawaiian forest birds
The introduced mosquito-borne avian malaria, Plasmodium relictum, along with its mosquito vector, Culex quinquefasciatus, are key limiting factors for endemic Hawaiian forest birds and are, in part, responsible for past extinctions and continued population declines of extant species. In the last 10 years steep declines in forest bird populations have been documented on Kaua`i and Maui...

Forest bird population status on Saipan, a small oceanic island Forest bird population status on Saipan, a small oceanic island
Tropical oceanic islands are critical biodiversity hotspots where population monitoring can help to determine the status and trends of rare and endangered species. Saipan is the second largest island in the Mariana Islands and contains many endemic and range-restricted bird species. Surveys of forest birds were conducted on Saipan using point-transect distance sampling, starting in 1982...

Distribution of yellow crazy ants (Anoplolepis gracilipes) and notes on other ant species at Wake Atoll, 6-21 October, 2023 Distribution of yellow crazy ants (Anoplolepis gracilipes) and notes on other ant species at Wake Atoll, 6-21 October, 2023
Wake Atoll, located in the central Pacific Ocean, is a tropical coral atoll comprised of three islands totaling 696 ha of emergent land. Wake Atoll supports at least 17 species of non-native ants, but one species, the yellow crazy ant (Anoplolepis gracilipes), is especially harmful to ecosystems, including seabirds, which are federally protected species and nest throughout Wake Atoll...

Early detection of wildlife disease pathogens using CRISPR-Cas system methods Early detection of wildlife disease pathogens using CRISPR-Cas system methods
Wildlife diseases are a considerable threat to human health, conservation, and the economy. Surveillance is a critical component to mitigate the impact of animal diseases in these sectors. To monitor human diseases, CRISPR-Cas (clustered regularly interspaced short palindromic repeats-CRISPR-associated protein) biosensors have proven instrumental as diagnostic tools capable of detecting...

Patterns and drivers of cottonwood mortality in the middle Rio Grande, New Mexico, USA Patterns and drivers of cottonwood mortality in the middle Rio Grande, New Mexico, USA
Riparian ecosystems are some of the most valuable and vulnerable on the planet. Riparian tree mortality is increasing in the western United States, where altered streamflows are combining with warming climate. Between 2011 and 2013, one third of an extensive stand of Populus deltoides var. wislizeni (Rio Grande cottonwood) died along the middle Rio Grande on the Pueblo of Santa Ana in...

Density estimation using spatial capture-recapture analyses: Application to vaccination of prairie dogs against sylvatic plague Density estimation using spatial capture-recapture analyses: Application to vaccination of prairie dogs against sylvatic plague
Prairie dogs are notoriously difficult to enumerate, with previously methods including visual counts, mark-resight, burrow counts, and catch per unit effort. Unlike those methods, spatial capture-recapture (SCR) analyses allow for formal estimation of density along with associated estimates of uncertainty, detection probability, and the size of the average area over which an individual...

Examining inter-regional and intra-seasonal differences in wintering waterfowl landscape associations among Pacific and Atlantic flyways Examining inter-regional and intra-seasonal differences in wintering waterfowl landscape associations among Pacific and Atlantic flyways
The Central Valley of California (CVC) and Mid-Atlantic (MA) in the U.S. are both critical sites for nationwide food security (California Poultry Federation 2016, Prosser et al. 2017), and many waterfowl species annually, especially during the winter, providing feeding and roosting locations for a variety of species. Mapping waterfowl distributions, using NEXRAD, may aid in the adaptive...

Identifying and filling critical knowledge gaps can optimize financial viability of blue carbon projects in tidal wetlands Identifying and filling critical knowledge gaps can optimize financial viability of blue carbon projects in tidal wetlands
One of the world’s largest “blue carbon” ecosystems, Louisiana’s tidal wetlands on the US Gulf of Mexico coast, is rapidly being lost. Louisiana’s strong legal, regulatory, and monitoring framework, developed for one of the world’s largest tidal wetland systems, provides an opportunity for a programmatic approach to blue carbon accreditation to support restoration of these ecologically...

A systematic review of laboratory investigations into the pathogenesis of avian influenza viruses in wild avifauna of North America A systematic review of laboratory investigations into the pathogenesis of avian influenza viruses in wild avifauna of North America
The lack of consolidated information regarding the response of wild bird species to infection with avian influenza virus (AIV) is a challenge to both conservation managers and researchers alike, with related sectors also impacted, such as public health and commercial poultry. Using two independent searches, we reviewed published literature for studies describing wild bird species...

Intraspecific trait variability in wild populations predicts neither variability nor performance in a common garden Intraspecific trait variability in wild populations predicts neither variability nor performance in a common garden
Dryland restoration requires plant materials capable of performing well despite difficult growing conditions. Selecting plant materials with higher intraspecific trait variability (ITV) may support successful outcomes by enhancing the performance of those materials in restoration settings. However, maintaining ITV from wild populations is not well understood and requires further...

Inventorying ponds through novel size-adaptive object mapping using Sentinel-1/2 time series Inventorying ponds through novel size-adaptive object mapping using Sentinel-1/2 time series
Ponds are an important source of greenhouse gases (GHGs) to the atmosphere, yet evaluating their role in global biogeochemical cycling is currently hampered by limitations in quantifying their global distribution. Existing satellite-derived estimates of lake distributions have difficulty identifying small lakes (5–10 ha) and ponds (
