Carbon dioxide (CO2) is under consideration as a chemical fish deterrent at pinch points in rivers (e.g., inside locks) to reduce unwanted fish passage. This study evaluated the behavioral responses of invasive round goby (Neogobius melanostomus) to dissolved CO2 in laboratory tanks. The goal of this project was to quantify CO2 concentrations that modify round goby behavior. More specifically, avoidance behavior (voluntary response) and loss of equilibrium (involuntary response) were quantified across 5, 15, and 25°C water temperatures. These data can be used to inform future field testing of CO2 as an invasive fish deterrent. Spreadsheets include data that were used to evaluate the efficacy of carbon dioxide (CO2)...
Unconventional oil development in the Bakken shale region has increased rapidly as a result of new technologies. This region also supports a particularly high density and diversity of grassland bird species, which are declining across North America. We examined grassland bird response to unconventional oil extraction sites (i.e. developed with hydraulic fracturing and horizontal drilling) and associated roads in North Dakota. Our goal was to quantify the amount of habitat that was indirectly degraded by oil development, as evidenced by patterns of avoidance by birds. Grassland birds avoided areas within 149 m of roads (95% CI: 4 – 294 m), 267 m of single-bore well pads (95% CI: 157 – 377 m), and 150 m of multi-bore...
The objective of this study was to document the vertical avoidance behavior of the tadpole madtom, as a surrogate to the northern madtom, in response to granular Bayluscide® when applied to control or assess larval sea lamprey populations. The data set consists of one hour recordings of the avoidance behavior of tadpole madtoms after exposure to granular Bayluscide. Each trial (replicated 15 times) consisted of three treated (Bayluscide granules) and three control (washed sand only) clear Plexiglas vertical columns (107 cm in height, 30.5 cm in diameter) with a single madtom per column. Video recordings were analyzed for vertical avoidance at 30 second intervals after addition of Bayluscide granules/washed sand...
Past research has suggested that during the calving period, caribou (Rangifer tarandus) in Arctic Alaska generally avoid areas within 1 km of oilfield roads with traffic. However, avoidance is not absolute, and caribou may habituate to infrastructure (e.g., buildings, roads, well pads) and human activity. We conducted road-based surveys of caribou in oilfields on Alaska’s Arctic Coastal Plain during the late calving and post-calving periods of June in 2000– 02. We recorded location, composition, and behavior of caribou groups located less than 1 km from active gravel roads and production pads. Caribou groups with calves were on average distributed farther from oilfield infrastructure than were groups without calves,...
