Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015-11-20) - Journal article,
Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
Nested row-column designs for near-factorial experiments with two treatment factors and one control treatment
(2015-10) - Journal article,
This paper presents some methods of designing experiments in a block design with nested rows and columns. The treatments consist of all combinations of levels of two treatment factors, with an additional control treatment.
Efficient abstracting of dive profiles using a broken-stick model
(2015-03) - Journal article,
For diving animals, animal-borne sensors are used to collect time-depth information for studying behaviour, ranging patterns and foraging ecology. Often, this information needs to be compressed for storage or transmission. ...
Using accelerometers to determine the calling behavior of tagged baleen whales
(2014-07-15) - Journal article,
Low-frequency acoustic signals generated by baleen whales can propagate over vast distances, making the assignment of calls to specific individuals problematic. Here, we report the novel use of acoustic recording tags ...
Estimating Key Largo woodrat abundance using spatially explicit capture–recapture and trapping point transects
(2016-06) - Journal article,
The Key Largo woodrat (Neotoma floridana smalli) is an endangered rodent with a restricted geographic range and small population size. Establishing an efficient monitoring program of its abundance has been problematic; ...
Modeling the aggregated exposure and responses of bowhead whales Balaena mysticetus to multiple sources of anthropogenic underwater sound
(2016-05-02) - Journal article,
Potential responses of marine mammals to anthropogenic underwater sound are usually assessed by researchers and regulators on the basis of exposure to a single, relatively loud sound source. However, marine mammals typically ...
A simulation approach to assessing environmental risk of sound exposure to marine mammals
(2017-04) - Journal article,
Intense underwater sounds caused by military sonar, seismic surveys, and pile driving can harm acoustically sensitive marine mammals. Many jurisdictions require such activities to undergo marine mammal impact assessments ...
Effects of a scientific echo sounder on the behavior of short-finned pilot whales (Globicephala macrorhynchus)
(2017-05) - Journal article,
Active echo sounding devices are often employed for commercial or scientific purposes in the foraging habitats of marine mammals. We conducted an experiment off Cape Hatteras, North Carolina, USA, to assess whether the ...
A path reconstruction method integrating dead-reckoning and position fixes applied to humpback whales
(2015-09-21) - Journal article,
BACKGROUND: Detailed information about animal location and movement is often crucial in studies of natural behaviour and how animals respond to anthropogenic activities. Dead-reckoning can be used to infer such detailed ...
Gauging allowable harm limits to cumulative, sub-lethal effects of human activities on wildlife : a case-study approach using two whale populations
(2016-08) - Journal article,
As sublethal human pressures on marine wildlife and their habitats increase and interact in complex ways, there is a pressing need for methods to quantify cumulative impacts of these stressors on populations, and policy ...
