| predicting the potential demographic impact of predators on their prey: a comparative analysis of two carnivore-ungulate systems in scandinavia. | 1. understanding the role of predation in shaping the dynamics of animal communities is a fundamental issue in ecological research. nevertheless, the complex nature of predator-prey interactions often prevents researchers from modelling them explicitly. 2. by using periodic leslie-usher matrices and a simulation approach together with parameters obtained from long-term field projects, we reconstructed the underlying mechanisms of predator-prey demographic interactions and compared the dynamics o ... | 2011 | 22077484 |
| Landscape resistance to dispersal: simulating long-term effects of human disturbance on a small and isolated wolf population in southwestern Manitoba, Canada. | Landscape fragmentation affects wildlife population viability, in part, through the effects it has on individual dispersal. In addition, some forms of human disturbance impinge on dispersal without physically fragmenting habitats. Here, we use the term "landscape resistance" to capture constraints to dispersal that cannot be linked directly to fragmentation. The extent to which landscape resistance can influence population persistence is not well understood. Agricultural development over the pas ... | 2011 | 22146824 |
| nucleotide polymorphisms in the canine noggin gene and their distribution among dog (canis lupus familiaris) breeds. | noggin (nog) is an important regulator for the signaling of bone morphogenetic proteins. in this study, we sequenced the complete coding sequence of the canine nog gene and characterized the nucleotide polymorphisms. the sequence length varied from 717 to 729 bp, depending on the number of a 6-bp tandem repeat unit (ggcgcg), an insertion that has not been observed in other mammalian nog genes investigated to date. it results in extensions of (gly-ala)(3-5) in the putative nog protein. to survey ... | 2011 | 21882044 |
| satellite telemetry of large mammals in mongolia: what expectations should we have for collar function? | the rapid pace of the development of satellite wildlife tracking tools has left little time for thorough testing of new equipment and identifying possible sources of technical failures. in the gobi and eastern steppe region of mongolia we deployed 98 satellite collars, collecting animal locations using the doppler based argos (n = 29) or the global positioning system (gps; n = 69), on 45 asiatic wild asses (equus hemionus), 34 mongolian gazelles (procapra gutturosa), 15 przewalski's horses (e. f ... | 2010 | 22003358 |

| genomic sweep and potential genetic rescue during limiting environmental conditions in an isolated wolf population. | genetic rescue, in which the introduction of one or more unrelated individuals into an inbred population results in the reduction of detrimental genetic effects and an increase in one or more vital rates, is a potentially important management tool for mitigating adverse effects of inbreeding. we used molecular techniques to document the consequences of a male wolf (canis lupus) that immigrated, on its own, across lake superior ice to the small, inbred wolf population in isle royale national park ... | 2011 | 21450731 |
| insects for breakfast and whales for dinner: the diet and body condition of dingoes on fraser island (k'gari). | top-predators play stabilising roles in island food webs, including fraser island, australia. subsidising generalist predators with human-sourced food could disrupt this balance, but has been proposed to improve the overall health of the island's dingo (canis lupus dingo) population, which is allegedly 'starving' or in 'poor condition'. we assess this hypothesis by describing the diet and health of dingoes on fraser island from datasets collected between 2001 and 2015. medium-sized mammals (such ... | 2016 | 27009879 |
| dietary differentiation and the evolution of population genetic structure in a highly mobile carnivore. | recent studies on highly mobile carnivores revealed cryptic population genetic structures correlated to transitions in habitat types and prey species composition. this led to the hypothesis that natal-habitat-biased dispersal may be responsible for generating population genetic structure. however, direct evidence for the concordant ecological and genetic differentiation between populations of highly mobile mammals is rare. to address this we analyzed stable isotope profiles (δ(13)c and δ(15)n va ... | 2012 | 22768075 |
| assessing predation risk to threatened fauna from their prevalence in predator scats: dingoes and rodents in arid australia. | the prevalence of threatened species in predator scats has often been used to gauge the risks that predators pose to threatened species, with the infrequent occurrence of a given species often considered indicative of negligible predation risks. in this study, data from 4087 dingo (canis lupus dingo and hybrids) scats were assessed alongside additional information on predator and prey distribution, dingo control effort and predation rates to evaluate whether or not the observed frequency of thre ... | 2012 | 22563498 |
| diet of wolves canis lupus returning to hungary. | at the end of the nineteenth century, the wolf canis lupus was extinct in hungary and in recent decades has returned to the northern highland area of the country. the diet of wolves living in groups in aggteleki national park was investigated using scat analysis (n = 81 scats) and prey remains (n = 31 carcasses). throughout the year wolves (average, minimum two wolves per year) consumed mostly wild-living ungulates (mean percent of biomass consumed, b% 97.2%; relative frequency of occurrence, %o ... | 2011 | 22448046 |
| genetic variability of the grey wolf canis lupus in the caucasus in comparison with europe and the middle east: distinct or intermediary population? | despite continuous historical distribution of the grey wolf (canis lupus) throughout eurasia, the species displays considerable morphological differentiation that resulted in delimitation of a number of subspecies. however, these morphological discontinuities are not always consistent with patterns of genetic differentiation. here we assess genetic distinctiveness of grey wolves from the caucasus (a region at the border between europe and west asia) that have been classified as a distinct subspe ... | 2014 | 24714198 |
