| a review of sarcoptic mange in north american wildlife. | the "itch mite" or "mange mite", sarcoptes scabiei, causes scabies in humans and sarcoptic mange in domestic and free-ranging animals. this mite has a wide host range due to its ability to adapt to new hosts and has been spread across the globe presumably through human expansion. while disease caused by s. scabiei has been very well-studied in humans and domestic animals, there are still numerous gaps in our understanding of this pathogen in free-ranging wildlife. the literature on sarcoptic man ... | 2019 | 31304085 |
| a six6 nonsense variant in golden retrievers with congenital eye malformations. | causative genetic variants for more than 30 heritable eye disorders in dogs have been reported. for other clinically described eye disorders, the genetic cause is still unclear. we investigated four golden retriever litters segregating for highly variable congenital eye malformations. several affected puppies had unilateral or bilateral retina dysplasia and/or optic nerve hypoplasia. the four litters shared the same father or grandfather suggesting a heritable condition with an autosomal dominan ... | 2019 | 31207931 |
| ontogeny vs. phylogeny in primate/canid comparisons: a meta-analysis of the object choice task. | the object choice task (oct) is a widely used paradigm with which researchers measure the ability of a subject to comprehend deictic (directional) cues, such as pointing gestures and eye gaze. there is a widespread belief that nonhuman primates evince only a weak capacity to use deictic cues; in contrast, domestic dogs (canis lupus familiaris) tend to demonstrate high success rates. this pattern of canid superiority has been taken to support the domestication hypothesis, which posits enhancing e ... | 2019 | 31170434 |
| the impact of selection for facial reduction in dogs: geometric morphometric analysis of canine cranial shape. | through artificial selection, humans have altered the morphology of domestic dogs and created the range of morphological traits present in the diverse dog breeds seen today. this article tests how artificial breeding for extreme facial reduction affects the craniodental complex in domestic dogs (canis lupus familiaris). these brachycephalic dog breeds allow for a natural experiment on facial reduction, providing additional insight into this well-studied phenomenon associated with the evolutionar ... | 2020 | 31152493 |
| tracking cryptic animals using acoustic multilateration: a system for long-range wolf detection. | the study of animal behavior in the wild requires the ability to locate and observe animals with the minimum disturbance to their natural behavior. this can be challenging for animals that avoid humans, are difficult to detect, or range widely between sightings. global positioning system (gps) collars provide one solution but limited battery life, and the disturbance to the animal caused by capture and collaring can make this impractical in many applications. wild wolves canis lupus are an examp ... | 2019 | 31067959 |
| testing the influence of habitat experienced during the natal phase on habitat selection later in life in scandinavian wolves. | natal habitat preference induction (nhpi) occurs when characteristics of the natal habitat influence the future habitat selection of an animal. however, the influence of nhpi after the dispersal phase has received remarkably little attention. we tested whether exposure to humans in the natal habitat helps understand why some adult wolves canis lupus may approach human settlements more than other conspecifics, a question of both ecological and management interest. we quantified habitat selection ... | 2019 | 31024020 |
| the timeline development of female canine germ cells. | during the sex differentiation, the primordial germ cells (pgcs) pass through a differentiation, becoming spermatogonial cells in males and oocytes in females. in this phase, there is difference in gene expression and differentiation potency between males and females. specific cell markers have been essential in the pgc meiosis beginning and become oocyte cells. however, there are few studies about germline in domestic animals. the domestic dog (canis lupus familiaris) is an interesting animal m ... | 2019 | 31006155 |
| estimating the intensity of use by interacting predators and prey using camera traps. | understanding how organisms distribute themselves in response to interacting species, ecosystems, climate, human development and time is fundamental to ecological study and practice. a measure to quantify the relationship among organisms and their environments is intensity of use: the rate of use of a specific resource in a defined unit of time. estimating the intensity of use differs from estimating probabilities of occupancy or selection, which can remain constant even when the intensity of us ... | 2019 | 30834526 |
| echinococcus granulosus in the endangered patagonian huemul (hippocamelus bisulcus). | cystic echinococcosis (ce) is a zoonotic parasitic disease associated with echinococcus granulosus. the parasite is maintained by domestic and wild canids as definitive hosts with several ungulate species as intermediate hosts in domestic and peridomestic transmission cycles. in chile, ce is endemic, and the role of livestock and dogs (canis lupus familiaris) in the cycle and the accidental infection of humans are widely documented at rural sites. however, the role of wild herbivores in wild cyc ... | 2019 | 30789781 |
| autochthonous cutaneous leishmaniasis in urban domestic animals (felis catus / canis lupus familiaris) from central-western venezuela. | leishmaniasis is a zoonotic disease caused by intracellular protozoa of the leishmania genus that are spread and transmitted by sandflies. natural infection and clinical disease in domestic cats and dogs appear to be rare or perhaps largely under-reported in endemic areas. however, previous reports on infected domestic animals usually implicate the same leishmania species that affect humans in tropical and subtropical areas of the world suggesting a potential role for zoonotic transmission. in t ... | 2019 | 30633896 |
| a second krt71 allele in curly coated dogs. | major characteristics of coat variation in dogs can be explained by variants in only a few genes. until now, only one missense variant in the krt71 gene, p.arg151trp, has been reported to cause curly hair in dogs. however, this variant does not explain the curly coat in all breeds as the mutant 151 trp allele, for example, is absent in curly coated retrievers. we sequenced the genome of a curly coated retriever at 22× coverage and searched for variants in the krt71 gene. only one protein-changin ... | 2019 | 30444027 |
