“…It is worth to note, that Hac et al (1996) found positive correlation between Hg content of the hair, kidneys, blood, and urine of A-I means in columns marked with the same upper case differ significantly at P ≤ 0.01 a-g means in columns marked with the same lower case differ significantly at P ≤ 0.05 rats intoxicated with mercury chloride. Statistically significant correlation (r = 0.321) was noted between Hg concentration in the hair and liver content of golden jackal (Canis aureus) (Malvandi et al 2010). Thus, the noninvasively collected hair samples may be useful in the assessment of heavy metals bioaccumulation in animal organs.…”

Mercury bioaccumulation in hair and skin of silver and arctic foxes farmed in typically rural and urbanized regions (Wielkopolskie Voivodship, Poland) was assessed. Hair and skin samples were collected and analyzed for total Hg content using atomic absorption spectrometry. Hairs and skin of foxes farmed in the rural region accumulated higher amount of Hg compared to animals from the urbanized one. Species effect (lower Hg concentration in V. lagopus) was noted, females having higher accumulation compared with males. The highest Hg content was observed in hairs of V. vulpes females in the rural region (0.207 mg/kg on average), and in skin of V. lagopus females (0.0082 mg/kg on average). Highly significant correlation (r = 0.796) was noted between Hg content in skin and hairs of farm foxes. The present study confirms the previous finding that non-invasively collected hair samples are a good tool applicable in evaluating heavy metal load of different environments.

“…Previous general studies, targeting all mammals of Iran in which golden jackal distribution is addressed, are often at a course scale (e.g., Etemad, 1985;Yusefi, Faizolahi, et al, 2019;Ziaie, 2008), and very few specific studies focusing Iranian golden jackals have been published in international peer-reviewed journals. To our knowledge, there are only three of these works, related to (a) methodological procedures for determination of body burden mercury using hair from jackals (Malvandi et al, 2010)…”

Generalist species are often characterized by low habitat specialization and reduced genetic structure in their populations. Here, we tested this common assumption on golden jackals in Iran, a wide country with a highly heterogeneous landscape where this carnivore is assumed to be widespread, although little is known about the ecology and population genetics of this species. We investigate distribution patterns, habitat requirements, and niche breadth of golden jackals by using GIS techniques and ecological modeling over a total of 452 presence records. We then assessed genetic diversity and population structure by analyzing 24 samples for 43 microsatellites. The observed distribution patterns show an extensive range across a wide climatic, ecological and altitudinal gradient, covering eight climate regions and 16 terrestrial ecoregions. Ecological modeling confirms high habitat plasticity of the golden jackal, with selection of mountainous areas with high slopes, moderate temperatures, and areas with low human population and activity while avoiding hyper-arid regions. Estimated values of niche breadth were high, indicating that is a generalist species in the study area. The observed genetic diversity was high, representing the highest value reported so far in this species. We found no signature of population structure, suggesting a single genetic cluster, as well as no evidence of hybridization with domestic dogs.Our results provide valuable ecological and genetic information on a widespread but poorly known carnivore, often disregarded in conservation strategies but under pressure from anthropogenic threats.

“…In fur‐bearing animals, it frequently has been observed that Hg levels in the hair are correlated to Hg concentrations in other tissues . Some studies have suggested that fur could be used as a noninvasive technique to determine Hg and/or MeHg concentrations in other tissues and organs , similar to what has been implemented in humans, whereby hair is used as a biological indicator of MeHg exposure .…”

Concentrations of metals in hair are used often to develop pharmacokinetic models for both animals and humans. Although data on uptake are available, elimination kinetics are less well understood; stable isotope tracers provide an excellent tool for measuring uptake and elimination kinetics. In the present study, methylmercury concentrations through time were measured in the hair and blood of mink (Neovison vison) during a controlled 60-d feeding experiment. Thirty-four mink were fed a standard fish-based diet for 14 d, at the end of which (day 0), 4 mink were sacrificed to determine baseline methylmercury (MeHg) concentrations. From day 0 to day 10, the remaining mink were fed a diet consisting of the base diet supplemented with 0.513 ± 0.013 µg Me(199) Hg/g and 0.163 ± 0.003 µg Me(201) Hg/g. From day 10 to day 60, mink were fed the base diet supplemented with 0.175 ± 0.024 µg Me(201) Hg/g. Animals were sacrificed periodically to determine accumulation of Me(201) Hg in blood and hair over the entire 60-d period and the elimination of Me(199) Hg over the last 50 d. Hair samples, collected from each mink and cut into 2.0-mm lengths, indicate that both isotopes of MeHg appeared in the hair closest to the skin at approximately day 10, with concentrations in the hair reaching steady state from day 39 onward. The elimination rate of Me(199) Hg from the blood was 0.05/d, and the ratio of MeHg in the hair to blood was 119. A large fraction of MeHg (22% to >100%) was stored in the hair, suggesting that in fur-bearing mammals the hair is a major route of elimination of MeHg from the body.
