Plasma progesterone levels during pregnancy and pseudopregnancy in the hare (Lepus europaeus syriacus)

Progesterone secretion during pregnancy and pseudopregnancy in the ferret.

In the ferret, pregnancy and pseudopregnancy last 6 weeks. Histological study of the CL and endometrium indicates a parallel rate of progestin secretion in the two conditions (Deanesly, 1967) and suggests that the products of conception do not affect CL activity in this species. Further evidence has been sought on this point by assay of the progesterone content of plasma samples collected from ...

Helminths Communities of an Introduced Hare ( Lepus 3 Granatensis ) and a Native Hare ( Lepus Europaeus ) in Southern 4 France

Preliminary reference values for electrocardiography, echocardiography and myocardial morphometry in the European brown hare (Lepus europaeus)

The study aimed at defining reference values for electrocardiographic (ECG) and echocardiographic parameters as well as macroscopic dimensions of the heart and microscopic dimensions of cardiomyocytes in the European brown hare. The studies were conducted on 30 adult, clinically healthy hares of either sex caught in Poland. ECG and echocardiography were performed supravitally on anaesthetized h...

The European Hare (Lepus europaeus): A Picky Herbivore Searching for Plant Parts Rich in Fat

European hares of both sexes rely on fat reserves, particularly during the reproduc-tive season. Therefore, hares should select dietary plants rich in fat and energy. However, hares also require essential polyunsaturated fatty acids (PUFA) such as linoleic acid (LA) and alpha-linolenic acid (ALA) to reproduce and survive. Although hares are able to absorb PUFA selectively in their gastrointesti...

Cytogenetic Studies on European Brown Hare, Lepus europaeus Pallas, 1778 (Lagomorpha: Leporidae) in Turkey

In this study, the karyotype, C-heterochromatin blocks, and nucleolar organizer regions (NORs) of four specimens of Lepus europaeus from Turkey were examined. The diploid number of chromosomes (2n), the fundamental number of chromosome arms (FN), and the number of autosomal arms (FNa) were determined as 48, 90, and 86, respectively. All of the chromosomes have been determined to be possessed of...
