Poor health is associated with use of anthropogenic resources in an urban carnivore
Abstract
Rates of encounters between humans and wildlife are increasing in cities around the world, especially when wildlife overlap with people in time, space and resources. Coyotes ( Canis latrans ) can make use of anthropogenic resources and reported rates of conflict have increased in cities across North America. This increase may be linked to individual differences in the use of human food and developed areas. We compared the relationships between coyote age, sex or health and the use of anthropogenic resources, which we defined as using developed areas over large home ranges, being active during the day, and consuming anthropogenic food. To do so, we applied GPS collars to 19 coyotes and sampled hair for stable isotope analysis. Eleven coyotes appeared to be healthy and eight were visibly infested with sarcoptic mange ( Sarcoptes scabiei ), a mite that causes hair loss. Diseased coyotes used more developed areas, had larger monthly home ranges, were more active during the day, and assimilated less protein than coyotes that appeared to be healthy. We speculate that anthropogenic food provides a low-quality but easily accessible food source for diseased coyotes, which in turn may increase reliance on it and other anthropogenic resources to promote encounters with people.

In the citing paper
“Coyotes in poor health (where state of health was assessed by the visible presence of sarcoptic mange) were more likely to use human‐developed areas (Murray et al., 2015)”

In the citing paper
“In addition, diseased coyotes assimilated 60% as much dietary protein as healthy coyotes.”
From Microbiomes in Canidae (2021) · cites this paper as Murray et al. (2015)
In the citing paper
“We believe our observations provide additional context to the concept of interacting conditions of stress, low‐quality diet, poor habitat, and decreased resistance to disease described by Murray et al. (2015) regarding urban coyotes in Alberta, Canada.”
From Microbiomes in Canidae (2021) · cites this paper as Murray et al. (2015)
In the citing paper
“Further, this observation makes it unlikely that the change seen in coyotes is caused by the presence of anthropogenic toxins, such as anticoagulant rodenticide that has been reported to affect urban bobcat populations (Riley et al., 2007; Serieys et al., 2018), and that has been suggested as a possible cause of anthropogenic stress in coyotes (Murray et al., 2015).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
