Impact of conservation and hunting on big game species: comparison of the genetic diversity of the red deer population groups from a national park and neighboring hunting areas in northern Poland

Abstract

The conservation of biodiversity and rational use of biological resources should be conducted with a view to population genetics. Thus, the purpose of this study was to compare the genetic diversity of highly distributed red deer groups from Słowiński National Park (NP) and hunting areas (HA) in northern Poland using 10 dinucleotide microsatellites. In 254 animals, 112 alleles were observed with a high allelic number (N A = 7-15). The NP and HA groups showed high mean heterozygosity (H o = 0.548 ± 0.-063-0.613 ± 0.061) compared to other deer populations in Europe, although a slight decrease in heterozygosity and an increase in inbreeding was identified in NP, compared to HA. A high level of intra-group and a low level of inter-group genetic differentiation was found, which was supported by a high level of gene flow between NP and HA. Structure analysis revealed two genetic clusters (NP and HA) within the population. The HA cluster was distinguished by numerous private alleles, although the NP cluster was distinguished by a high frequency of two private alleles. These study results show that unhunted conservation areas may affect red deer density without increasing genetic diversity whereas hunting does not seem to have a negative impact on deer genetic diversity. This study affirms the anthropogenic impact on the red deer groups in both NP and HA. Ongoing monitoring of the red deer population with an effective sampling strategy is recommended.
