Delphinid echolocation click detection probability on near-seafloor sensors
(2016-09) - Journal article,
The probability of detecting echolocating delphinids on a near-seafloor sensor was estimated using two Monte Carlo simulation methods. One method estimated the probability of detecting a single click (cue counting); the ...
A unifying model for capture-recapture and distance sampling surveys of wildlife populations
(2015) - Journal article,
Spatially explicit capture-recapture (SECR) methods extend traditional capture-recapture methods for estimating population density by using information contained in the location of traps. The The central feature of the ...
An efficient acoustic density estimation method with human detectors applied to gibbons in Cambodia
(2016-05-19) - Journal article,
Some animal species are hard to see but easy to hear. Standard visual methods for estimating population density for such species are often ineffective or inefficient, but methods based on passive acoustics show more promise. ...
Distance software: design and analysis of distance sampling surveys for estimating population size
(2010) - Journal article,
1. Distance sampling is a widely used technique for estimating the size or density of biological populations. Many distance sampling designs and most analyses use the software Distance. 2. We briefly review distance sampling ...
Incorporating animal movement into circular plot and point transect surveys of wildlife abundance
(University of St Andrews, 2018) - Thesis,
Estimating wildlife abundance is fundamental for its effective management and conservation. A range of methods exist: total counts, plot sampling, distance sampling and capture-recapture based approaches. Methods have ...
A risk function for behavioral disruption of Blainville’s beaked whales (Mesoplodon densirostris) from mid-frequency active sonar
(2014-01) - Journal article,
There is increasing concern about the potential effects of noise pollution on marine life in the world’s oceans. For marine mammals, anthropogenic sounds may cause behavioral disruption, and this can be quantified using a ...
Spatio-temporal variation in click production rates of beaked whales : implications for passive acoustic density estimation
(2017-03) - Journal article,
Passive acoustic monitoring has become an increasingly prevalent tool for estimating density of marine mammals, such as beaked whales, which vocalize often but are difficult to survey visually. Counts of acoustic cues ...
Techniques for estimating the size of low-density gopher tortoise populations
(2017-12-01) - Journal article,
Gopher tortoises (Gopherus polyphemus) are candidates for range-wide listing as threatened under the U.S. Endangered Species Act. Reliable population estimates are important to inform policy and management for recovery of ...
Passive acoustic monitoring of beaked whale densities in the Gulf of Mexico
(2015-11-12) - Journal article,
Beaked whales are deep diving elusive animals, difficult to census with conventional visual surveys. Methods are presented for the density estimation of beaked whales, using passive acoustic monitoring data collected at ...
A description of LATTE outputs
