Following a 10-month survey, we were able to collect a total of 117 living scorpions, they are grouped into 8 species belonging to two large families (Buthidae and Scorpionidae). Indeed, it is at the Teiher station in the wilaya of Tlemcen where the large number of scorpions was collected about 90 individuals. According to the results of the outings and among the scorpions sampled, it appears that the animals belong to the Buthidae family of which 6 species have been identified namely: Androctonus amoreuxi, Androctonus australis, Buthus tuneatanus, Buthus oudjanii, Hottentotta franzwerneri and Orthochirus innesi. Concerning the Scorpionidae family, two species of which have been identified, namely: Scorpio maurus and Scorpio punicus. The largest species in size is Hottentota franzwerneri with a total length of 101 mm (cephalothorax 12 mm, abdomen 29 mm and tail 60 mm). Equitability is close to one for the Zebche station, we noticed at this station that the species tend to be in numerical equilibrium, however in the Teiher station, the fairness is zero which is a result of dominance of only one species. \u0000","PeriodicalId":12670,"journal":{"name":"GABJ","volume":"58 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90434632","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}

The female has never raised any of her litters and all cubs have died soon after birth. Zoo staff hypothesized, that this could be due to several management factors including stress induced from the parking lot/road situated just outside the enclosure and the female’s lack of experience with raising cubs. A willow fence was put up to isolate the dogs visually from the outside. The purpose of this study was to analyze if habitat enrichment and olfactory enrichment could affect the behavioral reaction patterns of the AWDs. Individual behavior patterns are an indicator of differences in personality and a measure of welfare. The study was divided into a control period, a habitat enrichment period and an olfactory enrichment period each consisting of 3 days with 8 hours of video recording per day. An ethogram, based on previous observations of the AWD and a pilot study, was composed, and all behaviors observed were categorized. Various analysis and plots showed that, although some differences in specific behaviors and behavioral reaction patterns were present, the AWDs did not have a clear difference in personality. A difference in behavioural instability was found between two dogs when introduced to the enrichments. Due to changes in activity, it was concluded that the male reacted more positively to the habitat enrichment and the female reacted more positively when introduced to the olfactory enrichment. Several other categories of behaviour were observed in this study but, due to a low degree of data saturation, only data for behaviours “locomotion” and “standing still” were considered saturated enough to be used for data analysis.","PeriodicalId":12670,"journal":{"name":"GABJ","volume":"84 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87147235","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}

This need efficient production potential from the chicken. This paper simulated different scenarios of breeding program for indigenous chicken and compared the selection response with realized genetic gain after one generation of selection. A one stage discrete generation deterministic simulation approach using SelAction program was used. Two genetic parameters were employed. The phenotypic variances and heritability used were 25,000g and 0.25, 3040 and 0.51, respectively. For each case, 300 hens and 50 cocks were selected to produce the next generation. Each cock was mated to 6 hens and each hen produced 6 offspring. The best 50% and 20% of females and males, respectively, were selected for mating. The expected selection response was simulated as follows; a) own performance b) own performance, full sibs and half sibs and c) own performance with full sibs, half sibs and BLUP information sources. A sire model of BLUP was used for realized selection response. The predicted genetic gain for all simulated programs were much lower than realized response. This realized genetic gain could only be achieved by higher selection intensity on cocks, however this would increase the inbreeding rate above recommended level. The breeding program has shown potential for improvement and success in body weight at 12 weeks of age. \u0000","PeriodicalId":12670,"journal":{"name":"GABJ","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79398539","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}

Seventeen species (17) bird species belonging to eleven (11) families were found: Ciconidae, Corvidae, Accipitridae, Passeridae, Hirundinidae, Motacillidae, Columbidae, Ardeidae, Sturnidae, Laridae, and Pelecanidae, among them sedentary species, migratory, the visitors, and invasive species, which are exploiting the discharge for feeding or rest.

Therefore, the exploration of caprine POU1F1 gene polymorphisms may be vital in the formulation of conservation and breed improvement strategies. In this study, POU1F1 gene was characterized for sequence polymorphisms in 366 individuals from two Nigerian goat breeds ((West African Dwarf (WAD) and Red Sokoto (RS)) and one South African goat breed (Kalahari (KR)). The effects of polymorphisms on litter size were investigated using linear mixed model. Two intronic mutations (g.306G>A and g.11236C>T) were identified. However, no significant association was found between the Single Nucleotide Polymorphisms (SNPs) and litter size in the three populations. The genetic distance based on POU1F1 investigated region revealed that the two Nigerian breeds and the South African breed were identical (pairwise genetic distance of 0.00). Phylogenetic tree constructed from the pairwise distance clustered the three breeds into a single clade with the two Nigerian goat breeds having a more recent common ancestor. Structural analysis of the POU1F1 protein confirmed that Pit-Oct-Unc transcription factors domain (POU) and Homeodomain (HOX) domains are conserved in mammals, with several overlapping sub-domains across the same region in all the three populations.
