The present study consists in making an inventory of the scorpionic fauna at the level of the Algerian north-west (Tlemcen, Naama and Bechar). 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.

In order to study the biodiversity of Cameroon’s indigenous pigs, this study was carried out from December 2017 to July 2018 in the Sudano-Guinean zone of Cameroon, precisely in the Bankim subdivision. Data on morphology and body measurements (17) were collected in eight localities from 287 randomly selected pigs of both sexes aged at least 8 months and analyzed. Diversity analyses showed that there is a significant variability in the population. Color pattern results show that Bankim pig has a multiple Coat color with a tendency of bicolor prevalence (58%). The ear orientations of pig were mainly front erected (65.50%). Body measurements were significantly (p ≤ 0.05) different among the localities except for hair length. The major body indices indicated that the Bankim pig could be an interesting candidate for meat production in small scale farming. According to the discriminant factorial analysis, the population may consist of three genetic types. Phylogenetic analysis showed that one of the genetic types is at genetic equidistance from the two others. The observed genetic variability within the studied populations may offer opportunity for genetic improvement.

This study is based on two African wild dogs (AWD) (Lycaon pictus), a male and a female, in Aalborg Zoo, Denmark. 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.

The demand for poultry meat, particularly from indigenous chicken, is ever increasing. 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.

The feed preferences of Conraua goliath, an endogenous frog in central Africa were assessed in the present study. A total of 65 frogs (22 males, 22 females and 21 unspecified frogs) were obtained from hunters in 3 localities namely: Loum, Penja, and Nlonako in the Moungo division, littoral region of Cameroon. The methods of dissection, measurement, and stomach content analysis were used. The results revealed a large diversity of preys in the stomach namely: myriapods (25%), plants leaves and steems (21.19%), insects (19.56%), indigestible matters (19.56%), arachnids (4.89%), crustaceans (4.34%), mollusks (3.26%), amphibians (0.54%), annelids (0.54%) and reptiles (0.54%). The numerical percentage and the frequency of myriapods occurrence were significantly (P < 0.05) higher in males captured in the locality of Loum (100% and 35.55%) compared to the females (28.57% and 18.18%). Comparing the state of maturity, the numerical percentage and the frequency of occurrence of insects (100% and 42.85%) and indigestible matters (100% and 42.85%) were significantly higher in the youngs frogs (61.11% and 20.89%) captured in Loum compared to the adults (22.22% and 7.46%). Frogs of high weight (˃1000g) recorded significantly (P < 0.05) higher occurrence and numerical frequency of myriapods (100 and 70%), indigestible and detritus materials (100 and 40%) in low-weight frogs (<400g) and plants leaves and steems (50 and 47.36%) in medium-weight frogs (400 – 1000g). In conclusion, goliath frog is an omnivore fed on a variety of preys and plants according to their availability in the environment.

Landfills have the advantage of meeting the energy needs of the birds quickly. They offer easy access to food and widely available throughout the year. In this study, birds were counted using observation points on an open landfill in the restored of Souk-Ahras region (north-eastern Algeria) for one year from July 2013 to April 2014. 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. Species richness and abundance in landfill site were found to be higher than that of naturel habitat around the site. Their abundance varied according to the seasons.landfill site support both common bird species as: Columba palumbus, Columba livia, Streptopelia decaoto, Ciconia ciconia, Corvus corax. In addition to that, rare bird species such as Pelecanus crispus. Ecology and dynamic of each species, during an annual cycle of bird’s populations allow us observing all the interactions and reactions between the individuals and the different populations of birds. Souk Ahras landfill is a resting place and a source of food for birds, which means that it needs a censuses urgency update of migratory birds which frequent our region as well as monitor their state of health. It is also interesting to follow the process of colonization in urban Souk Ahras city.

Between February and May 2019, in the equatorial forest urbanized area of Cameroon (Mfoundi), a study was conducted and aimed to contribute on a better understanding of the biodiversity of edible snails for their genetic improvement and conservation. A total of 693 adult snails of two species: Archachatina marginata and Achatina fulica were collected in the various localities (Odza, Mbankolo, Biyem-assi, Nyom, Nkolbisson and Simbok). Information about biometric morpho characters was collected using a survey sheet, an electronic scale of 7000g capacity with accuracy of plus or minus 1g, a sliding foot with an accuracy of plus or minus 0.01 millimeter. A digital camera will be used for the subsequent morphological assessment of the animals. Results revealed significant influence of locality on all the morphobiometric characteristics. The shell color of A. marginata was black with yellowish stripes and the red tip was the most frequent (62.85%); while for the species A. fulica it was brown with white stripes and white tip (76.09%). The most common color of the foot in A. marginata was brown with white traces (41.70%) and in A. fulica, it was black (82.50%). The number of shell turns in A. marginata was higher in the localities of Mbankolo (5.36±0.12) and Odza (5.38±0.05) while in A. fulica it was higher in the locality of Simbok (7.41±0.49). Concerning body measurements (in mm), the total body length of A. marginata was higher in Nkolbisson (88.10±1.30) and that of A. fulica was greater in Simbok (112.25±12.16). The live weight (g) of A. marginata was higher in Mbankolo (70±0.00) on the other hand, that of A. fulica was higher in Simbok (80±0.02) and Nyom (80±0.12). The diversity observed suggests that edible snails constitutes rich natural genetic resources enough variability to envisage genetic improvement and develop preservation schemes for these snails mostly collected from wild

POU1F1 gene controls cell differentiation and animal growth by binding to target DNA promoter sequence, thereby auto-regulating its own expression and expression of growth hormone (GH), prolactin (PRL) and thyroid-stimulating hormone beta sub-unit (TSHβ) genes. 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. We found a subdomain Subfamily of SANT domain or myb/SANT-like domain in Adf-1 (MADF) in goat, cattle, buffalo and camel that has not been reported in mammals

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.

Lebanon is an eastern Mediterranean country with a small population of only 4 million (Abbas et al. 2020). It is characterized for its distinct human genetic, cultural, ethnic, and religious diversity (Haber et al. 2011). The average live twinning births rate in Lebanon is 18.9/1000 (Romanos & Borjac, 2018). Twins can be either monozygotic (MZ) or dizygotic (DZ). The difference between them is how they are formed during embryogenesis (Hoekstra et al. 2008). When a single sperm fertilizes a single egg, it splits then in two genetically identical twins (Xu et al. 2015). However, in fraternal twins case, separate eggs are fertilized by separate sperm to yield genetically different twins (Martino et al. 2013).
黎巴嫩是一个东地中海国家，人口只有400万(Abbas et al. 2020)。它的特点是其独特的人类遗传、文化、种族和宗教多样性(Haber et al. 2011)。黎巴嫩的平均活双胞胎出生率为18.9/1000 (Romanos & Borjac, 2018)。双胞胎可以是同卵(MZ)或异卵(DZ)。它们之间的区别在于它们在胚胎发生过程中是如何形成的(Hoekstra et al. 2008)。当一个精子与一个卵子受精时，它会分裂成两个基因相同的双胞胎(Xu et al. 2015)。然而，在异卵双胞胎的情况下，不同的卵子由不同的精子受精，产生基因不同的双胞胎(Martino et al. 2013)。

The study was carried out from August to September 2016 in the Western Highlands of Cameroon. The main objective was to contribute to a better understanding of biodiversity of honeybees for their preservation and genetic improvement. To attain this, samples of 420 workers bees belonging to Apis mellifera subspecies were obtained from 14 localities in the study zone. Body measurements in mm gave the following values: honey bee length (10.98 ± 0.06), abdomen length (6.71 ± 0.03), width of the yellow band on the second (2nd) abdominal tergite (1.48 ± 0.01), width of fourth (4th) abdominal tergite (1.32 ± 0.01), length of cover hair on the fifth (5th) abdominal tergite (0.29 ± 0.00), antenna length (4.27 ± 0.02), proboscis length (4.39 ± 0.11), length of nervure A (0.60 ± 0.00), length of nervure B (0.25 ± 0.00), discoidal shift (-0.13 ± 0.01), anterior right wing length (9.31 ± 0.03), anterior right wing width (3.14 ± 0.01), posterior right wing length (6.38 ± 0.03) and posterior right wing width (1.69 ± 0.01). A correlation coefficient significantly (p<0.01) higher (0.72) was obtained between the length of posterior right wing and the length of the anterior right wing. The cubital index is 2.36 ± 0.04. Populations of honeybees studied consist of three genetic types; genetic types 2 and 3 are closer together. The observed biodiversity suggests that honeybees constitute a natural resource with genetic variability needed for preservation and genetic improvement.
