Abstract The investigation and management of the impacts winter tick ( Dermacentor albipictus ) infestations on moose Alces alces in North America necessitates coordinated surveillance intervention efforts. However, variations parasite methods potential biases towards sampling specific host species for this generalist can impede attempts to standardize observed disease patterns across vast regions into future. We collected classified records ungulate hosts throughout identify trends species,...
Concerns that climate warming may drive the spread of ectoparasites into previously uninhabited areas have increased need for baseline knowledge their distributional history. For species wildlife health concern, presence data are often lacking or outdated, thus limiting our ability to assess range changes and subsequent host impacts. We reconstructed past present distribution winter tick, Dermacentor albipictus, through compilation a spatiotemporal database create first full map its...
Abstract Background The winter tick ( Dermacentor albipictus ) has garnered significant attention throughout North America for its impact on wildlife health, and especially moose Alces alces ), where high burdens may result in host hair loss, anemia, can prove fatal. environmental transmission of D. larvae to a is critical event that direct infestation success, yet in-field observations this life stage are lacking. In Yukon, Canada, had previously been found hosts, but larval not detected...
Sampling hides from harvested animals is commonly used for passive monitoring of ectoparasites on wildlife hosts, but often relies heavily community engagement to obtain spatially and temporally consistent samples. Surveillance winter ticks (Dermacentor albipictus) moose (Alces alces) caribou (Rangifer tarandus caribou) hosts in Yukon, Canada, has relied part voluntary submission by hunters since 2011, few samples were submitted. To enhance sampling efforts underrepresented we implemented a...
Abstract Predicting the spatial and temporal dynamics of invasive species is critical for successful management intervention, yet substantial uncertainty exists about how will interact with human pathways when introduced to new ecosystems. We demonstrate a novel approach quantifying predicting uptake, movement, establishment by combining mechanistic modeling spread process expert opinion demographic factors that govern performance. utility this using case study involving transfer potential...
Parasites exhibit a diverse range of life history strategies. Transmission to host is key component each cycle but the difficulty observing host–parasite contacts has often led confusion surrounding transmission pathways. Given limited data on most systems, flexible approaches are needed for disentangling obscure dynamics these systems. Here, we develop modelling framework formally testing long‐standing hypotheses regarding how parasitic nematode Trichinella nativa maintained at high...
Fishes assessed as Threatened or Endangered by the Committee on Status of Wildlife in Canada are disproportionately less likely to be listed under federal Species at Risk Act (SARA) compared other taxa. We examined extent which amount and type science advice a Recovery Potential Assessment (RPA) contributes SARA-listing decisions for 34 wildlife species freshwater fishes Canada. used generalized linear mixed model describe SARA listing status function RPA completeness.
