Modelling harbour seal movements
(Scottish Government, 2017-10-11) - Report,
Double-observer line transect surveys with Markov-modulated Poisson process models for overdispersed animal availability
(2015-12) - Journal article,
We develop maximum likelihood methods for line transect surveys in which animals go undetected at distance zero, either because they are stochastically unavailable while within view or because they are missed when they are ...
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 ...
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 ...
Sex differences in confidence influence patterns of conformity
(2017-11) - Journal article,
Lack of confidence in one's own ability can increase the likelihood of relying on social information. Sex differences in confidence have been extensively investigated in cognitive tasks, but implications for conformity ...
Estimates of local biodiversity change over time stand up to scrutiny
(2017-02) - Journal article,
We present new data and analyses revealing fundamental flaws in a critique of two recent meta-analyses of local-scale temporal biodiversity change. First, the conclusion that short-term time series lead to biased estimates ...
A new approach to estimate fecundity rate from inter-birth intervals
(2017-04) - Journal article,
Accurate estimates of fecundity rate are key to population assessments and effectively direct conservation efforts. We present a new approach to estimate fecundity rate based on the probability of a female giving birth, ...
Neonicotinoids target distinct nicotinic acetylcholine receptors and neurons, leading to differential risks to bumblebees
(2016-04-28) - Journal article,
There is growing concern over the risk to bee populations from neonicotinoid insecticides and the long-term consequences of reduced numbers of insect pollinators to essential ecosystem services and food security. Our ...
Late Neoarchean subduction-related crustal growth in the Northern Liaoning region of the North China Craton : evidence from ∼2.55-2.50 Ga granitoid gneisses
(2016-08) - Journal article,
The North China Craton (NCC), dominated by ∼2.6-2.5 Ga tectonothermal events, provides a natural laboratory to study Neoarchean crustal growth and geodynamic evolution. Late Neoarchean granitoid gneisses are well exposed ...
Estimation bias under model selection for distance sampling detection functions
(2017-09) - Journal article,
Many simulation studies have examined the properties of distance sampling estimators of wildlife population size. When assumptions hold, if distances are generated from a detection model and fitted using the same model, ...
