Analysis of Fibropapillomatosis in Roe Deer () Confirms High Content of Heavy Metals.

In recent decades, there has been an increase in European wild ungulate populations, often associated with a decline in health and spread of disease. This is true for the roe deer (), the most common European cervid, with populations apparently affected by fibropapillomatosis, an increasingly common cancer. To date, however, there has been little research into this disease, thus many interactions remain unclear and descriptions of tumour composition are poorly validated.

First findings of brown hare (Lepus europaeus) reintroduction in relation to seasonal impact.

In Europe, brown hare (Lepus europaeus) populations have been declining steadily since the 1970s. Gamekeepers can help to support brown hare wild populations by releasing cage-reared hares into the wild. Survival rates of cage-reared hares has been investigated in previous studies, however, survival times in relation to seasonality, which likely plays a crucial role for the efficacy of this management strategy, has not been evaluated.

[Tumors in wildlife].

Wild animal tumours have not been much studied yet. Authors found six mostly benign cases in Czech Republic in checking hunts between the years 1988 and 1993: Mature differentiated ovarian teratoma and apocrine skin adenoma in field hare, intraductal mammary papillomatosis in a roe, complex odontoma and pleomorphic mammary carcinoma (single malignancy in the group) in fox. A soft tissue tumour in a fallow-buck's neck could not be histogenetically classified.

[Extracellular ceroid in the adipose tissue of the field hare (Lepus europaeus Pall.)].

Routine histology of hares caught for ecological monitoring showed extracellular curvilamellar ceroid in a focal degeneration process of reserve adipose tissue in 19 animals. The defect was localized most frequently in parametrial adipose tissue, in mesovary, close to suprarenals and in spleen hilus. Discussion concerned an analogical process in men and other animal species and a possible role of vitamin E deficiency.

[Detection of aflatoxin B1 in tissues of free-living game animals (Lepus europaeus, Phasianus colchicus, Capreolus capreolus, Anas platyrhynchos)].

This contribution states concentrations of products of toxogenic mould fungus Aspergillus in livers, kidneys and testes of specific game animals. In hares (Lepus europaeus), there was determined an average concentration in livers of 0.407 microgram.
