Mixture models for distance sampling detection functions
(2015-03-20) - Journal article,
We present a new class of models for the detection function in distance sampling surveys of wildlife populations, based on finite mixtures of simple parametric key functions such as the half-normal. The models share many ...
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. ...
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 ...
Higher biodiversity is required to sustain multiple ecosystem processes across temperature regimes
(2015-01) - Journal article,
Biodiversity loss is occurring rapidly worldwide, yet it is uncertain whether few or many species are required to sustain ecosystem functioning in the face of environmental change. The importance of biodiversity might be ...
The effect of animal movement on line transect estimates of abundance
(2015-03-23) - Journal article,
Line transect sampling is a distance sampling method for estimating the abundance of wild animal populations. One key assumption of this method is that all animals are detected at their initial location. Animal movement ...
Inter-annual and seasonal trends in cetacean distribution, density and abundance off southern California
(2015-02) - Journal article,
Trends in cetacean density and distribution off southern California were assessed through visual line-transect surveys during thirty-seven California Cooperative Oceanic Fisheries Investigations (CalCOFI) cruises from July ...
Phenotype specific analyses reveal distinct regulatory mechanism for chronically activated p53
(2015-03-19) - Journal article,
The downstream functions of the DNA binding tumor suppressor p53 vary depending on the cellular context, and persistent p53 activation has recently been implicated in tumor suppression and senescence. However, genome-wide ...
5-hydroxymethylcytosine marks promoters in colon that resist DNA hypermethylation in cancer
(2015-04-01) - Journal article,
Background : The discovery of cytosine hydroxymethylation (5hmC) as a mechanism that potentially controls DNA methylation changes typical of neoplasia prompted us to investigate its behaviour in colon cancer. 5hmC is ...
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 ...
