Cím:Comparative Analysis of body weight and condition in two brown hare populations / Farkas Péter, Majzinger István
Dátum:2017
ISSN:2063-4803
Megjegyzések:The condition of the populations are useful parameters for the reasonable game management. In this study the physical condition of Brown hare stocks (Lepus europaeus, Pallas 1785) was analyzed, measured body weight (BW) and determined kidney fat index (KFI). These methods were applied during our survey in the hunting period of 2014/15 and 2015/16. In total 272 (123 male and 149 female) samples were collected from two hunting areas in Great Plain (from County Békés and Jász-Nagykun Szolnok). The aim of our work was to collect data concerning the conditions of the populations. All hares was sexed and classified in 2 age groups (young <1years), and (old> 1years). The age was established by Stroh-mark in the hunting field and by dried eye lenses in the laboratory. BW and the weight of the kidney and perirenal fat was measured and the data were statistically analysed (group statistics, Levene's test for Equality of Variances and, t-tests for Equality of Means). As a result of our examination the range of KFI was 1.25-5.14. The weight of perirenal fat was between 2-34gramm.KFI was greater in females than males. The average BW of the hares in every age groups were less than it is according to literature dates, however the conditions of the hares were good and in very good in both hunting areas. The BW and the amount of the perirenal fat in adult female hares were the greatest.

Cím:Examination of age distribution, time of birth and survival in a brown hare population / Majzinger István, Farkas Péter
Dátum:2022
ISSN:2677-0792 2063-4803
Megjegyzések:Our research goal was to examine the (1) age distribution, the (2) date of birth and the (3) survival rate of a brown hare (Lepus europaeus) population. We would like to contribute new data to the results so far. Data were collected between 2014 and 2016 in an agricultural region (Jász-Nagykun Szolnok and Békés county) of Hungary. We examined altogether 346 shot animals from the hunting bag. (1) There was no statistical difference between the years 2014 and 2015 when examining the homogeny of the age distribution of the whole autumn population. At the same time, age distributions between 2015-2016 and 2014-2016 can be considered to be different. The age distribution of under one year old individuals in 2014-2015 and 2015-2016 were different, but it can be considered homogeneous between 2014 and 2016. 1. (2) Most of the young hares were born between March and July in all three consecutive years, in detail: III-IV. 22%, IV-VI. 27% and VI-VII. 16% (altogether 65%) of all offspring. (3) The survival rate (lx) of the whole population was 0,55 in T1 period (from 2015 to 2015), and 0,45 in T2 (from 2015 to 2016) by under 1 year olds, while in the group of 1-2 years old or older, it was 0,79 in T1 and 0,81 in T2. Examining the survival rate of the two age groups, no significant difference can be seen during the examined periods. Examined by age groups and sex, the survival rate was 0,62 for under 1 year old males in T1 period, while it was 0,37 in T2; furthermore by the age group of 1-2 years old and older the survival rate was 0,74 in T1, and 0,64 in T2. The survival among males was homogeneous in the two years. The survival of females by under 1 year olds was 0,49 in T1, while 0,54 in T2. By the age group of 1-2 years old and older, the survival rate was 0,81 in T1, and 0,91 in T2. The survival of females between the two years was also homogeneous.
