Dissolved organic and inorganic carbon in a Southeast Alaskan watershed (2021) Dissolved organic and inorganic carbon in a Southeast Alaskan watershed (2021)
Data from high frequency sampling of multiple carbon forms were collected in a predominately rain-fed watershed in Southeast Alaska during the main run-off season (May-October 2021). The dataset includes hourly measurements of stream temperature, specific conductivity, turbidity, and fluorescent dissolved organic matter, point samples of dissolved organic carbon (DOC), alkalinity...
Juvenile coho salmon growth differences track biennial pink salmon spawning patterns Juvenile coho salmon growth differences track biennial pink salmon spawning patterns
Spawning salmon provide marine derived resources to freshwater ecosystems that can benefit stream-dwelling fish foraging and growth. Pink salmon are widely distributed throughout watersheds along the north pacific ocean, and display distinct biennial fluctuations in spawning abundance. These data were collected from a coastal watershed in northern southeast Alaska (Montana Creek) to...
Stream Attributes and Habitat Intrinsic Potential Model Results to examine Freshwater Habitat Potential for Chinook Salmon in the Yukon and Kuskokwim River Basins, Alaska Stream Attributes and Habitat Intrinsic Potential Model Results to examine Freshwater Habitat Potential for Chinook Salmon in the Yukon and Kuskokwim River Basins, Alaska
Chinook Salmon (Oncorhynchus tshawytscha) are an important commercial, subsistence, and recreational fishery resource in Alaska, and recent population declines have resulted in closures of some Chinook Salmon fisheries. Research into environmental factors involved in the decline of salmon stocks has exposed information gaps regarding fine-scale freshwater habitat quality known to...
Riverine carbon form and flow data from a temperate forested watershed in Southeast Alaska (2021) Riverine carbon form and flow data from a temperate forested watershed in Southeast Alaska (2021)
Data from high frequency sampling of multiple carbon forms were collected in a predominately rain-fed watershed in Southeast Alaska during the main run-off season (May-October 2021). The dataset includes dissolved organic carbon, particulate organic carbon, coarse particulate organic carbon, and invertebrate biomass carbon point samples and daily stream flow. The objective of this study...
Data describing hypoxia vulnerability in the salmon watersheds of Southeast Alaska Data describing hypoxia vulnerability in the salmon watersheds of Southeast Alaska
This .zip file contains five products that will allow users to recreate the analyses and spatial data figures used in Sergeant et al. 2023, Hypoxia Vulnerability in the Salmon Watersheds of Southeast Alaska: 1) Hypoxia vulnerability calculations (.csv file) at water temperature monitoring sites, 2) Hypoxia vulnerability calculations (.csv file) for stream reaches near hatchery release...
Stream hydrology and a pulse subsidy shape patterns of fish foraging Stream hydrology and a pulse subsidy shape patterns of fish foraging
Pulsed subsidy events create ephemeral fluxes of hyper-abundant resources that can shape annual patterns of consumption and growth for recipient consumers. However, environmental conditions strongly affect local resource availability for much of the year, and can heavily impact consumer foraging and growth patterns prior to pulsed subsidy events. Thus, a consumer’s capacity to exploit...
Population genetic analysis of three aquatic macroinvertebrate species from samples in Grand Canyon (Arizona, USA) tributaries and nearby reference streams, 2016-2021 Population genetic analysis of three aquatic macroinvertebrate species from samples in Grand Canyon (Arizona, USA) tributaries and nearby reference streams, 2016-2021
This dataset contains single nucleotide polymorphism (SNP) information for aquatic insect species collected in tributaries of the Colorado River in Grand Canyon (Arizona, USA), as well as SNP information for individuals collected from reference reaches of the Upper Colorado River Basin in Utah. This dataset focuses specifically on three species that were common and widely distributed...
