Population Estimates for Selected Breeding Seabirds at Kilauea Point National Wildlife Refuge, Kauai, in 2019 Population Estimates for Selected Breeding Seabirds at Kilauea Point National Wildlife Refuge, Kauai, in 2019
Kilauea Point National Wildlife Refuge (KPNWR) is an important seabird breeding site located at the northeastern tip of Kauai in the main Hawaiian Islands (MHI). Despite the regional significance of KPNWR as one of the most important breeding sites for Red-tailed Tropicbirds (Phaethon rubricauda), Red-footed Boobies (Sula sula), and Wedge-tailed Shearwaters (Ardenna pacifica) in MHI...
Aquaculture and Irrigation Water-Use Model (AIWUM) Version 1.0 Estimates and Related Datasets for the Mississippi Alluvial Plain, 1999-2017 (ver. 2.0, April 2021) Aquaculture and Irrigation Water-Use Model (AIWUM) Version 1.0 Estimates and Related Datasets for the Mississippi Alluvial Plain, 1999-2017 (ver. 2.0, April 2021)
This data release contains monthly and annual water-use estimates from the Aquaculture and Irrigation Water-Use Model version 1.0 for the Mississippi Alluvial Plain, April 1999 to October 2017. Aquaculture and irrigation estimates contained in this data release are representative of groundwater withdrawal for six different categories: aquaculture, cotton, corn, rice, soybeans, and all...
Characteristics of Sites Sampled for eDNA of Amphibians in Mendocino County, California, 2016 Characteristics of Sites Sampled for eDNA of Amphibians in Mendocino County, California, 2016
Stream-obligate amphibians are important indicators of ecosystem health in the Pacific Northwest, but distributional information to improve forest management is lacking in many regions. We analyzed archived DNA extracted from water samples in 60 pools within streams in private timberlands in Mendocino County, California, for 3 California Species of Special Concern - Coastal Tailed Frogs...
Pacific Northwest tidal marsh plant biomass from a 2017 greenhouse experiment with flooding and salinity manipulations Pacific Northwest tidal marsh plant biomass from a 2017 greenhouse experiment with flooding and salinity manipulations
The sensitivity of tidal marshes to environmental changes that result from sea-level rise or drought conditions is uncertain. We used a controlled greenhouse experiment and factorial flooding x salinity treatments to explore the differential responses of three tidal marsh plant species. Each species exhibited unique responses, with negative responses to increased salinity and longer...
Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries Comparisons of Gambel's quail survey methods conducted in 2016 within the Mohave Desert of California with results and summaries
Data includes results collected in the Mohave Desert during 2016 using three survey methods (acoustic recording units, camera traps, and call-count surveys) to detect gamebirds, primarily Gambel's quail (Callipepla gambelii) but also including records of mourning dove (Zenaida macroura), Eurasian collared-dove (Streptopelia decaocto), and chukar (Alectoris chukar). ARU data includes the...
Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015) Coastal California Gnatcatcher Habitat Suitability Model for Southern California (2015)
This habitat model was developed to delineate a sampling frame for regional monitoring of coastal California gnatcatchers (Polioptila californica californica) to determine: 1) percent area occupied (PAO) in high and very high suitability habitat across conserved lands and participating military lands in the U.S. range in southern California; 2) changes in PAO over time; and 3) extinction...
