Potentially toxic element accumulation in badgers (Meles meles): a compositional approach

نویسندگان

چکیده

Potentially Toxic Elements (PTEs) in Badgers (Meles meles), otherwise known as heavy metals, are unique amongst environmental pollutants occurring, both naturally and anthropogenically. PTEs have a broad range of negative health effects, therefore identifying their sources pathways through the environment is imperative for public policy. This difficult terrestrial systems due to compositional nature soil geochemistry. In this study, statistical approach was used identify how accumulate carnivorous mammal, Eurasian meles). Compositional principal component analysis (PCA) on geochemical data from Tellus survey, baseline badger tissue map geo-spatial patterns show accumulative trends measured time. Mapping PCs identified distinct regions PTE presence accumulation tissues Northern Ireland. were most elevated liver, kidney then muscle tissues. Liver showed depleted.

Why Are Group-living Badgers (meles Meles) Sexually Dimorphic?

One of the hypotheses proposed to account for why badgers Meles meles are highly social in the U.K., the resource dispersion hypothesis, is that patchy resources are unpredictably dispersed in the environment and therefore must be shared, but that these patches are rich enough, when available, to support several badgers at any one time. Previous empiricists in our study site at Wytham Woods cal...

Model of Selective and Non-Selective Management of Badgers (Meles meles) to Control Bovine Tuberculosis in Badgers and Cattle

Bovine tuberculosis (bTB) causes substantial economic losses to cattle farmers and taxpayers in the British Isles. Disease management in cattle is complicated by the role of the European badger (Meles meles) as a host of the infection. Proactive, non-selective culling of badgers can reduce the incidence of disease in cattle but may also have negative effects in the area surrounding culls that h...

Tuberculosis in European badgers (Meles meles) and the control of infection with bacille Calmette-Guérin vaccination.

The eradication of tuberculosis (Mycobacterium bovis infection) from cattle herds may be compromised if infected wildlife species, such as European badgers (Meles meles), share the same environment and contribute to transfer of infection. Options for dealing with tuberculosis in this wild reservoir host are limited by conservation and social concerns, despite a clear implication that infected b...

Reproductive skew and relatedness in social groups of European badgers, Meles meles.

Reproductive skew is a measure of the proportion of individuals of each sex that breed in a group and is a valuable measure for understanding the evolution and maintenance of sociality. Here, we provide the first quantification of reproductive skew within social groups of European badgers Meles meles, throughout an 18-year study in a high-density population. We used 22 microsatellite loci to an...
