Handling times: tagging vs photos, Boreal toads in WY/CO 2020 Handling times: tagging vs photos, Boreal toads in WY/CO 2020
Individual identification is required for investigations that examine population-level changes (e.g., decreased survival, increased disease prevalence) and the mechanisms associated with these changes in wild populations. Such identification generally requires the application of a unique mark, or the documentation of characteristics unique to each individual animal. Marking strategies...
Assessing the Status and Trends of Seabirds and Forage Fish in Lower Cook Inlet, Alaska Assessing the Status and Trends of Seabirds and Forage Fish in Lower Cook Inlet, Alaska
This data release is composed of seven datasets regarding colonial seabirds and forage fish at two seabird nesting colonies on Gull and Chisik Islands in lower Cook Inlet, Alaska. These data were collected to detect changes in the breeding population of Black-legged Kittiwakes and Common Murres on two nesting colonies in lower Cook Inlet and to compare those counts to baseline counts...
Multi-objective Modeling as a Decision-support Tool for Feral Horse Management Multi-objective Modeling as a Decision-support Tool for Feral Horse Management
Decisions related to controversial problems in natural resource management receive the greatest support when they account for multiple objectives of stakeholders in a structured and transparent fashion. In the United States, management of feral horses (Equus caballus) is a controversial multi-objective problem because disparate stakeholder groups have varying objectives and opinions...
Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs Assessing the Northeastern Gulf of Mexico Microtidal Wetland System Change in the Apalachicola-Big-Bend Region Under Sea-Level-Rise: Model Inputs and Outputs
Using the Hydrodynamic-Marsh Equilibrium Model (Hydro-MEM), the wetlands system within the Apalachicola-Big-Bend region of Florida (FL) (Fig. 1) was assessed using three sea-level rise scenarios of intermediate-low (50 centimeters [cm] by 2100), intermediate (1 meter [m] by 2100), and intermediate-high (1.5 m by 2100) from the National Oceanic and Atmospheric Administration (NOAA). Hydro...
Microsatellite Loci for Mogollon Narrowheaded Gartersnake (Thamnophis rufipunctatus) and the Northern Mexican Gartersnake (Thamnophis eques megalops) in Arizona and New Mexico (2020-2021) Microsatellite Loci for Mogollon Narrowheaded Gartersnake (Thamnophis rufipunctatus) and the Northern Mexican Gartersnake (Thamnophis eques megalops) in Arizona and New Mexico (2020-2021)
The Mogollon Narrowheaded gartersnake (Thamnophis rufipunctatus) and the Northern Mexican gartersnake (Thamnophis eques megalops) are both listed as Threatened under the Federal Endangered Species Act. Both species have a strong association with aquatic habitats, and these habitats have been highly altered from impoundments, land-use changes, and the introduction and spread of non-native...
