Distribution. Sub-Saharan Africa; virtually eradicated from W Africa, and greatly reduced in C and NE Africa. The largest populations exist in Botswana, Tanzania, and Zimbabwe, which account for approximately half of the estimated number of African Wild Dogs remaining in the wild. Other populations occur in Central African Republic, Ethiopia, Kenya, Mozambique, Namibia, South Africa, Sudan, and Zambia. Potential small populations (less than 100 individuals) may exist in Cameroon, Chad, Senegal, and Somalia. in Canidae

Data from: Prairie dogs, cattle subsidies, and alternative prey: Seasonal and spatial variation in coyote diet in a temperate grassland
<p class="MsoNormal"><span>As the dominant predator on North America's grasslands, coyotes (<em>Canis latrans</em>) have a large influence on biodiversity, both on working ranches and in protected parks. Ground squirrel (sciurid) species and livestock carrion are often abundant on grasslands worldwide and have the potential to influence a predator's consumption of alternative prey. We collected 1321 scats in four seasons over two years in and adjacent to Grasslands National Park, Saskatchewan, to test the hypothesis that seasonal and spatial variation in consumption of sciurid prey and cattle (<em>Bos taurus</em>) carrion influenced coyote consumption of alternative prey.<strong> </strong>Sciurid (black-tailed prairie dog <em>Cynomy</em>s<em> ludovicianus</em> and Richardson's ground squirrel </span><em>Urocitellus richardsonii</em><span>) remains were common from spring to fall and had a strong inverse relationship with deer (mule deer <em>Odocoileus hemionus</em> and white-tailed deer <em>O. virginianus</em>), which were most common in winter scats. Cattle remains were most common during spring, fall and winter, occurring in 10.6% of scats annually. Biomass estimates indicated that cattle was the highest ranked food on cattle grazing land year-round, and the 2<sup>nd</sup> ranked food, after deer, during winter on the portion of the park from which cattle were excluded. Closer proximity of scats to a prairie dog colony increased the likelihood of prairie dog remains throughout the year and reduced the likelihood of cattle remains in scats from spring to fall, but not during winter. Individual differences in foraging and ranging behavior may explain the spatial distribution of prairie dog versus cattle in scats. </span><span>Further work is needed to determine whether </span><span>sciurid prey, deer, or livestock carrion </span><span>support large predator populations on grassland habitats to a level that may negatively affect coexisting prey species, including species at risk.</span></p>
Genetic diversity and relatedness among African Painted dogs in North America
<p>African painted dogs (<em>Lycaon pictus, </em>APD) are highly endangered, with fewer than 7,000 remaining in nature. Captive breeding programs can preserve a genetically diverse population and provide a source of individuals for re-introductions. However, most programs are initiated from few founders and suffer from low genetic diversity and inbreeding. The aims of this study were to use molecular markers to assess genetic variation, inbreeding, and relatedness among APDs in the North American captive population, to use these data to realign studbook records, and to compare these data to wild populations and to the European captive population to facilitate development of a global management plan. We sequenced mitochondrial and major histocompatibility (MHC) class II loci, and genotyped 14 microsatellite loci from 109 APDs from 34 institutions in North America. We identified three likely studbook errors and resolved ten cases of uncertain paternity. Overall, microsatellite heterozygosity was higher than reported in Europe, but effective population size estimates were lower. Mitochondrial sequence variation was extremely limited, and there were fewer MHC haplotypes than in Europe or the wild. Although the population did not show evidence of significant inbreeding overall, several individuals shared high relatedness values, which should be incorporated into future breeding programs.</p>

Calculations for: Detector dog work assessing probability of detection for Yellow crazy ant
<p class="MsoNormal">The use of detector dogs within environmental programs has increased greatly over the past few decades, yet their<span> </span><span>search methods are not standardised, and variation in dog performance remains not well quantified or understood. There is much science to be done to improve the general utility of detector dogs, especially for invertebrate surveys.</span></p> <p class="MsoNormal">We report research for detector dog work conducted as part of yellow crazy ant eradication. One dog was first used to quantify probability of detection (POD) within a strictly controlled trial. We then investigated the search patterns of two dogs when worked through sites using different transect spacings. Specifically we quantified their presence within set distances of all locations in each assessment area, as well as the time they took to assess each area. In a GIS we then calculated the relative percentage of the entire search area within six distance categories, and combined this information with the POD values to obtain a site-level POD.</p> <p class="MsoNormal">The calculated relationship between distance and POD was extremely strong (R<sup>2</sup> = 0.998), with POD being 86% at 2 m and 28% at 25 m. For site-level assessments conducted by the two dogs, both dogs achieved highest site-level POD when operated on the lowest transect spacing (15 m), with POD decreasing significantly as transect spacing increased. Both dogs had strong linear relationships between area assessed and time, with the area assessed being greater when the transects had greater spacing. The working style of the two dogs also resulted in significantly different assessment outcomes. In one hour one dog could assess approximately 9.2 ha with transects spaced 20m apart, and 6.8ha with transects spaced 15 m apart, whereas the second dog could only assess approximately 6.9 ha with transects spaced 20 m apart, and 4.9 ha with transects spaced 15 m apart.</p> <p class="MsoNormal">Our study provides insight into the ability of dogs to detect yellow crazy ants, and sets the basis for further science and protocol development for ant detection. With the lessons learnt from this work we then detail protocols for using detector dogs for ant eradication assessments.</p>

On taming the effect of transcript level intra-condition count variation during differential expression analysis: a story of dogs, foxes and wolves: Bowtie2 counts and kallisto abundances
<p>Intra [1] and inter [2-5] study RNA-seq read datasets representing the varying brain compartments of foxes (n=24), as well as dogs (n=14) and wolves (n=6), as described in Lobo <em>et al.</em>, (2022) (under review), were mapped to the dog reference transcriptome [6], which contained 26,107 annotated transcripts (Ensembl CanFam3.1, release 92) [7], using Bowtie2 v.2.3.4.1 [8] and using kallisto v0.46.1 [9]. Count data obtained following each mapping approach for each dataset had high correlations (Lobo <em>et al.</em>, Figure S2). Bowtie2 counts were subsequently used in multiple differential analysis experiments in order to explore the effects of intra-condition count variation on the detection of differentially expressed transcripts. The individual count and abundance datasets for each corresponding RNA-seq dataset are available here.</p> <p> </p> <p>A preprint of Lobo et al., 2022, currently under review for PLOS ONE, is available [10]. The preprint however does not contain reviewer requested information on simulations as this, along with other additions including an additional author RL, has been subsequently added during the review process.

Comparison of behavioural tendencies between 'dangerous dogs' and other domestic dog breeds – evolutionary context and practical implications
<p>Aggressive behaviour by dogs is a considerable social problem, but the ability to predict which individuals may have increased aggressive tendencies is very limited, restricting the development of efficient preventive measures. There is a common perception that certain breeds are more likely to exhibit aggressive behaviour, which has contributed to the introduction of breed-specific legislation. The rationale for such legislation explicitly assumes high heritability of this trait while also implying relatively little variation within breeds; these assumptions are largely untested. We compared behavioural tendencies between 8 breeds that are subject to legislation in at least one country and 17 breeds that are not subject to legislation using two validated psychometric tools: the Dog Impulsivity Assessment Scale (DIAS), which scores elements of impulsivity, including a tendency for aggressive behaviour, and Positive and Negative Activation Scale (PANAS), which scores sensitivity to positive and negative stimuli (which may trigger aggressive responses). We found that the two groups of breeds do not differ significantly in the specific DIAS factor relating to aggressive behaviour, "Aggression Threshold and Response to Novelty", or any other DIAS and PANAS factors. We found large variation in all behavioural tendencies measured by both psychometric scales within both groups and within each breed studied. Taken together, our findings indicate that breed alone is not a reliable predictor of individual behavioural tendencies, including those related to aggression, and therefore breed-specific legislation is unlikely to be an effective instrument for reducing risk.</p>

Innominate Dog Bone EOA:2022.90.3
Innominate dog bone from the wreck of the Earl Of Abergavenny. ID: EOA:2022.90.3 Collection: Earl of Abergavenny Classification: Remains Measurements: Length 113mm Width 260mm Date made: as yet unknown Display: not on display Manufacturer/Creator: as yet unknown Credit: Portland Museum Trust This pelvic bone is one of several dog bones recovered and suspected to be from the same animal. Comparisons with modern breeds suggest it to be from a terrier sized dog. It is possible that this dog could have been on board as a rat catcher, rats being a well documented pest on board ship.
