“…It is also probable that parasites only absorb particular heavy metals into their tissue. Several heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) were analyzed among red foxes, yet only infected foxes with Echinococcus multilocularis illustrated lower levels of Cd and Pb compared to uninfected red foxes [ 65 ]. In conjunction with our study, these investigations suggest parasites capability to bioaccumulate particular heavy metals at higher concentrations than their host perhaps delays, or hinders, the onset of heavy metal toxicity.…”

Monitoring the bioaccumulation of chemical elements within various organismal tissues has become a useful tool to survey current or chronic levels of heavy metal exposure within an environment. In this study, we compared the bioaccumulations of As, Cd, Cu, Fe, Pb, Se, and Zn between the American alligator, Alligator mississippiensis, and its parasites in order to establish their use as bioindicators of heavy metal pollution. Concomitant with these results, we were interested to determine if parasites were more sensitive bioindicators of heavy metals relative to alligators. We found parasites collectively accumulated higher levels of As, Cu, Se, and Zn in comparison to their alligator hosts, whereas Fe, Cd, and Pb concentrations were higher in alligators. Interestingly, Fe levels were significantly greater in intestinal trematodes than their alligator hosts when analyzed independently from other parasitic taxa. Further analyses showed alligator intestinal trematodes concentrated As, Cu, Fe, Se, and Zn at significantly higher levels than intestinal nematodes and parasites from other organs. However, pentastomids also employed the role as a good biomagnifier of As. Interestingly, parasitic abundance decreased as levels of As increased. Stomach and intestinal nematodes were the poorest bioaccumulators of metals, yet stomach nematodes showed their ability to concentrate Pb at orders of magnitude higher in comparison to other parasites. Conclusively, we suggest that parasites, particularly intestinal trematodes, are superior biomagnifiers of As, Cu, Se, and Zn, whereas alligators are likely good biological indicators of Fe, Cd, and Pb levels within the environment.

“…This data is similar to the study of E . multilocularis and red foxes, suggesting that parasites may better absorb or buffer their hosts from particular heavy metals analogous to other heavy metals [ 65 ]. However, it must be taken into consideration that extreme levels of these metals could likely cause parasite mortality.…”

“…In residential areas, urban food waste piles can provide an abundant food source for carnivores and omnivores (Newman et al 2003, Scott et al 2014, 2018. On the other hand, urban areas also pose multiple challenges to the survival of wildlife, for example due to a lack of natural food sources and habitats (McDonald et al 2008), risk of death from road traffic collisions, pollution (Brožová et al 2014, Newport et al 2014, Altermatt & Ebert 2016, Mullineaux et al 2020) and competition or predation by free-roaming domestic pets (Loyd et al 2013, Doherty et al 2017).…”

Urban environments provide opportunities for some species but are inhospitable for others. However, those which thrive can be found at higher densities in human‐dominated landscapes than in more rural habitats. This highlights the importance of understanding species responses to human environments. It is not only important for the conservation of urban wildlife but also may provide fundamental insights into human‐wildlife coexistence globally. Here, we use citizen science data to predict the habitat suitability of Greater London for the West European hedgehog (Erinaceus europaeus), the red fox (Vulpes vulpes), the European badger (Meles meles) and the Eastern grey squirrel (Sciurus carolinensis). Results indicate that the four target species prefer different urban habitats, indicating different levels of urbanisation potential. Foxes and grey squirrels are able to thrive in inner urban areas, with the highest values of habitat suitability for these species found in central London, whereas for hedgehogs and badgers, the highest habitat suitability occurs in suburban and more rural habitats in outer London, respectively. These results highlight a gradient in urban tolerance, from squirrels and foxes to hedgehogs and badgers. This work also shows the importance of urban green spaces as habitats for wildlife.

The effects of plant-bound zinc (Zn) and cadmium (Cd) on element uptake and their interactions in a parasite-host system were investigated in a model experiment. Male Wistar rats were divided into four groups (C, P, TC and TP). Groups TC and TP were infected with the rat tapeworm Hymenolepis diminuta. Groups C and TC were fed a standard rodent mixture (ST-1) and received 10.5 mg of Zn per week, while groups P and TP were fed a mixture supplemented with the Zn- and Cd-hyperaccumulating plant Arabidopsis halleri at a dosage of 236 mg Zn/week and 3.0 mg Cd/week. Rats were euthanized after 6 weeks, and Cd and Zn levels were determined in rat and tapeworm tissue. The results indicate that tapeworm presence did have an effect on Cd and Zn concentrations in the host tissue; the majority of tissues in infected rats had statistically significant lower Zn and Cd concentrations than did uninfected rats. Tapeworms accumulated more zinc and cadmium than did the majority of host tissues. This important finding confirms the ability of tapeworms to accumulate certain elements (heavy metals) from the host body to their own body tissues. Thus, tapeworms can decrease heavy metal concentrations in host tissues.
