Studies have found that different enrichment strategies can help activate the bears, thereby changing their behaviour and decrease stereotypies. When observing polar bears, it is apparent that individuals exhibit behaviours with different frequencies, which makes it relevant to examine if the animals have different behavioural reaction norms. This study aims to investigate the behaviour of two polar bears in Aalborg Zoo and how enrichments changes their behaviour. Furthermore, it investigates if the polar bears differ in behavioural patterns, reflecting differences in behavioural reaction norms. Although no significant differences were found, the results suggest an association between enrichments and decreased stereotypical behaviour for one bear while there was no detectable change in stereotypical behaviour for the other bear. The different reaction patterns for the two bears, may be due to different behavioural reaction norms e.g. individual differences in neophobia and exploratory behavior. In future studies presentation of the enrichment objects before the test days, may yield more heterogeneous results easier to interpret.","PeriodicalId":12670,"journal":{"name":"GABJ","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78975917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Single nucleotide polymorphisms (SNPs) were filtered with a read coverage between 20 - 100 and a maximum number of missing data of 25 %. Individuals with > 25 % missing data were removed yielding a total of 2.4 million SNPs, and after filtering for Minor allele frequency (MAF) >1 %, 2902 SNPs remained. Approximately half of the individuals analysed contained less than 75% of the selected SNPs, and were removed, resulting in a sample size of 30. We estimated inbreeding coefficients (F), observed (HO), expected (HE) and unbiased expected (uHE) heterozygosity and the percent of polymorphic loci (P%). We tested for deviations from Hardy-Weinberg equilibrium (HWE) and patterns of isolation by distance (IBD). We assessed the genetic structure of the sampled individuals based on a Bayesian clustering method, and tested for recent population expansion or decline. We found a P% = 94.5%, a uHE and HE of mean ± SE; 0.31 ± 0.04 and 0.30 ± 0.02, respectively and an HO of 0.290 ± 0.03. The heterozygosity deficiency was reflected in a positive F-value; 0.1 ± 0.01 and a significant deviation for HWE (p < 0.05). The Mantel test for association between the genetical and geographical distances of populations was not significant (b = 0.007, R = 0.145, p > 0.05). The significant and positive F-value found, was explained by inbreeding, genetic substructure and low effective population size (Ne) which are all consequences of habitat fragmentation. We failed to detect recent signs of a population bottleneck or expansion. Further studies on a larger scale are needed to obtain a general view of the conservation status of the Danish hedgehog population.","PeriodicalId":12670,"journal":{"name":"GABJ","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91014169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourteen measurements in which 11 quantitative and three qualitative traits were carried out in this work. The results obtained for all measurements made on the population BRAHMA chickens in the region of Tlemcen with the 8 communes visited, show that there is a significant difference between the morphological characters except two characters length of the tarsi (LT) and width of the thighs (LAC). Furthermore, In addition, sex shows a small significant difference between the measurements studied.Thus the results of the PCA and hierarchical classification show that there are four groups that share the same morphological characteristics except for some differences that may be due to climatic and environmental adaptation.

This review focuses on a synthesis of knowledge on the Borgou cattle breed farming in Benin. It gathers information about its origin, its physical and ethnological characteristics. It also highlights the characterization of rearing modes, its adaptation to different farming systems, the analysis of its productivity and its genetic improvement. Studies of several authors, reports of various structures that intervene in livestock farming system in Benin have been involved in this review. It should be noted that the Borgou cattle breed is a trypanotolerant taurine breed from northern Benin. The breed has shown by its traits a remarkable adaptation to its natural environment and has the advantage of enhancing natural rangelands and especially wetlands infested with tsetse flies and hostile to zebu cattle farming. If particular attention is paid to livestock farming in rural areas, this breed has the potential to improve and increase production from cattle farming in Benin. Likewise, uncontrolled crossbreeding of this breed with other native breeds or even exotic breeds presents risks of genetic loss to the detriment of crossbreds becoming more and more vulnerable to environmental conditions","PeriodicalId":12670,"journal":{"name":"GABJ","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86214328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
