The Genetic and phenotypic characterization of the Central AfricanBlackbelly sheep was carried outfrom April 1st to November 30th2019. A total 288adults sheep were sampled in order to assess the genetic diversity of the Blackbelly population in 3 Central Africa countries (Cameroun, Congo Brazzaville and Gabon).A total of twenty-two (22) body measurements were collected with the aid of metric tools(i.e.,headlength, head width, hornlength, ear length, neck length, neck circumference, total body length, trunk length, height at withers, height at back, height at rump, chest circumference, chest depth, chest width, rump width, rump length, front leg length, rear leg length, tail length, canon bone circumference, nipple length and body weight). The latter was used to calculate twelve (12)indices (sub-sternal gracility, ear-length, format, compactness, massiveness, chest,slenderness, frame, body, dactylo-thoracic, caudal and ear) in a bid to appreciate the functional relationship between measurements. Phenotypic dimorphism (P ≤ 0.05) has been observed between the Blackbelly sheep of different countries, with the highest and heaviest animals coming from Congo (HW= 62.217 ± 5.288 and BW = 27.44 ± 6.08kg), the longest from Gabon (TBL = 84.69 ± 8.70) and the largest (CW=15.01± 2.531 and RW=14.716 a± 2.351) from Cameroon. A perfect correlation was recorded between BW and TC. Principal Component Analysis reveals that six main components explain 73.1% of the observed variability in the body measurements of Blackbelly sheep population of Central Africa. The first two components which have eigenvalues greater than 3 and explain 25.44% (CP1) and 17.41% (CP2) of the variability in body measurements, can be considered for an improvement and selection program. Hence, the height at back and thethoracic circumference appear to be the most interesting measurements to beconsidered for the selection and conservation of the Blackbelly sheep.

In the context of the evaluation of animal genetic resources in general and the diversity of land snails in particular, we contributed to a morphometric and phenotypic study of this animal groupes 14 districts whose, they are recognized by their snail production. To achieve the objective measurements with geometrical approaches were collected from 751 individuals. Four parameters related to the body of each animal as the height of the shell (HC), the length of shells (LC),shell width (LGC) and the weight (P) and two phenotypic characters flesh color (CCH) and shell color (CC). The ANOVA test show a significant differences on body measurements between districts andspecies. In fact, the obtained results show that the Otala punctate is the most common species in Algeria; otherwise, there is significant phenotype variability betweenindividuals, which confirms that snails exhibit a large polymorphism. An Independence test was carried out on the phenotypic characteristics revealing that the regions influence the qualitative characteristics.This study it one of very few research undertaken in this field especially in Algeria. It is an important approach to be taken into consideration during conservation and improvement programs for this endangered species because of illegalpickup.

Diet studies of carnivores are often based on analysis of prey remains found in scats or stomachs. In these analyses differences in decomposition rate and the degree of digestion of the prey item must be taken into consideration. In studies of raccoon dog diets, eggshells are rarely found. This may be due to three possible scenarios, which may act in combination: 1) raccoon dogs rarely eat bird´s eggs in the wild, 2) raccoon dogs eat eggs without swallowing shell parts, 3) rapid digestion of swallowed eggshells, so that they are only present briefly in stomach contents. In this study, the feeding behaviour of raccoon dogs on eggs of different sizes was observed under semi-natural conditions in an enclosure and the dissolution time of eggshells was examined. Dissolution time of eggshells of different thicknesses was tested experimentally using different concentrations of hydrochloric acid. The study showed a negative relationship between egg size/shell thickness and the amount of shell ingested by the raccoon dog. No eggshell, independent of bird species, was degraded beyond detectability after 12 hours in hydrochloric acid at pH 3.3. A correction factor estimating the mass of eggshell (g) ingested by the raccoon dog was calculated from the dry mass of eggshell found in the stomach or scat. Also the amount of eggshell estimated to be degraded by gastric acid is given. This correction factor ranged from 14 to 282 depending on eggshell thickness and egg size. From this study, it can be concluded that raccoon dogs do ingest some eggshell and that it is possible to detect eggshells in stomachs and scats of raccoon dogs, suggesting that the lack of eggshell in diet samples probably reflects a low proportion of eggs in the diet and/or preying more heavily on large eggs that are cracked open and have their contents eaten, rather than small eggs that are eaten shell-and-all.

The pine processionary (Thaumetopoea pityocampa) is the most important defoliator of coniferous forest of the Mediterranean basin. The pine processionary also caused real public health problems. The urticat property is the origin of its health problems. It is still the subject of several studies to this day in order to develop friendly control strategies that respect the environment. The study carried out about the characterization of the pine processionary populations in two stations of pine forests located at the area of the Tlemcen. The caterpillars were collected in January 2016 in the Tlemcen region. Measurements were performed on L5 larvae and male and female nymphs. The statistical analyses were carried out using the SAS 9 software. The results obtained show that the females have an average length of 11.51 ± 1.07 mm and an average width of 7.87 ± 0.33 mm. Males have an average length and width of 11.51 ± 1.07 mm and 6.48 ± 0.29 mm, respectively. The length and width of the head capsule is 43.28 ± 6.63 mm and 4.50 ± 1.35 mm respectively. The GLM procedure of the SAS.9 software allowed us to observe that the Sebdou station is more attacked by this insect compared to the Ghazaouet station despite that there is a similarity between the biometric characters of the pine plants. Our statistical analyses have also shown that trees with the longest needles are the most resistant against insect attack.

Measuring behavioural differences for captive Sumatran tigers (Panthera tigrissumatrae) is a useful tool for the optimisation of captive environments and animal welfare. Behavioural differences can be measured by comparing several individuals and by comparing days with enrichment to days without enrichment. The behaviour of two individuals can vary for reasons such as age and sex, where age can play a part in the activity level of an individual as well as age-related diseases can impact behavior. Using statistical analyses on data collected by observing tigers (n=4) in Aalborg Zoo, Denmark, throughout 15 days, it was possible to visualize and calculate significant changes in behaviour when comparing enrichment and control days. The main focus of this study was the individual behavioural differences on enrichment and control days.All individuals showed increased activity on enrichment days. This study also aimed to investigate whether meloxicam had an effect on the behaviourof an aged male Sumatran tiger as a tool to assess if he had pain. No significant behavioural changes were observed in the behaviour of the tiger with or without meloxicam treatment. In conclusion, there were differences in the behaviour of individuals of different age andsex and how the individuals reacted to enrichment.

Studies suggest that the welfare of captive chimpanzees can be improved by providing different kinds of enrichments. Sensory enrichment has gotten more attention lately, by e.g. using sounds and images. The purpose of this study was to examine the differences in behavior, using asleep meditationpodcast asenrichment.An ethogram wasmade to categorizethe different behaviors. The difference between the medians of each behaviorwas then tested with a Mann-Whitney U test. Furthermore, the personalities of the chimpanzees were analyzed, byfirst plotting X-Y graphs of the median, kurtosis, skewness, and IQR.Afterward, χ2 tests were performed on the slopes, todetermineif there were any significant differences in the chimpanzee’s personalities.Additionally, behavioral diversity was calculated and compared with χ2 tests. Based on these tests, it was not possible to conclude whether the sleep meditation causedachange in behavior in the enrichmenttestperiod. It is however possible to conclude that the study showed a significant difference in the personalities, between some of thechimpanzees.

Growth traits characterization of Nigeria homing pigeons was done using one hundred and thirty eight (138) birds from three locations (LCT) of different agro-ecological zones in Nigeria [Kebbi (KEB):North West; Ilorin (ILR): North Central and Osogbo (OSG): South West]. Parameters measured were body weight (BW) in gram and morphometric body parameters in cm viz. Head length (HL), beak length (BL), neck length (NL), body length (BL), body girth (BG), wing length (WL), body height (BH), thigh length (TL), drumstick length (DL) and keel length (KL). The results showed that, significant (p<0.05) differences existed between body weight and body parameters measured except BL. ILR pigeons had significantly (p<0.05) higher BW (263.51g) compared to OSG (204.15), but similar (p>0.05) to KEB (249.76g); the morphometric body parameters measured showed that HL, BG and WL values were significantly (p<0.05) higher in ILR; OSG had significantly (p<0.05) higher values for KL, while KEB pigeons had significantly (p<0.05) higher values for BL, NL, BH, TL, DL, and SL. Positive and significant correlations (p<0.01, 0.05) exists between locations, NL, SL and BH; BW was negatively correlated with locations with a significant (0.01) value of -0.58. PCA shows the clustering of growth traits from 18.94 to 25.14% under PC1 and 2, canonical discriminant functions gouped KEB and OSG with 56.60%; ILR and KEB with 43.60% while hierarchical clustering shows that KEB homing piegons are distinct from those of ILR and OSG. This results shows that locations have significant effects on growth traits in Nigeria homing pigeons.

Bats are among the most remarkable mammals with extraordinary adaptations. They play a key role in the ecosystem. It is well known that bats are also reservoirs for many viruses. However, their bacterial flora is relatively less explored. According to our bibliographic research, very little work has been carried out on the saliva of bats. The present study describes the microbial diversity associated with the saliva of two species of bats (Myotis Punicus and Rhinolophes ferrumequinum) in Sebdou region (Tlemcen), Algeria. The microbiological, biochemical and molecular examination of the bat saliva allowed to identify 14bacterialgenera:Pseudomonas, Chryseomonasluteola, Staphylococcus spp., Shigella, Raoultellaornithinolytica, Enterobacter cloacae, Enteratia fudicariaii, Serrobatia fudicariaii, odorifera, Suterobacter cloacoe, Suterobacter sakazakii, Salmonella charizonae, Salmonella choleraesuis ssp arizone, Klebsiella oxytoca, Proteus Mirabilis and Yersinia.

Eight hundred broiler chickens of four different strains (200 each of Arbor Acre, Hubbard, Marshall and Ross 308) were used to investigate the variations between four strains of broiler chickens commonly reared in North central Nigeria using their body weight and some morphometric body parameters. At four weeks of age, body weight and some morphometric body parameters such as body length, keel length, shank length, body height, drumstick length, thigh length, wing length, shank circumference, comb length, body girth, neck length and beak length were appropriately measured. Data obtained were used for principal component, stepwise discriminant and cluster analyses mainly to identify the traits that could best describe the broiler body conformation. Four (4) principal components were extracted in Arbor Acre broiler strains; this explained 56.68% of the total variation in the parameters sampled across the strains. Six (6) principal components (PC) were extracted for Hubbard and Ross strains, while three (3) principal components were extracted for Marshall and these explained 59.46%, in Hubbard, 58.67% in Ross and 55.52% of the total variance, respectively. The result also showed that PC1 had the largest share of the total variance which was highly significant in the studied morphometric traits and discriminate each of the strain studied. Canonical discriminant functions showed a distinct Hubbard under function1 and a distinct Marshall under function 2. Standardized canonical discriminant analysis indicated that wing length and body girth had highest value for discriminating under function1 and 2, respectively. This study indicates that available strains of broiler chickens can be distinguished through the use of some multivariate analysis.

The Mediterranean basin has significant natural resources including a proven diversity of flora. The Anacardiaceae family has around 800 tropical and subtropical species, with some representatives around the Mediterranean. Most of the plants of this family are non- toxic plant. They even have many properties. Our work consists to study the bio-insecticidal power of essential oils of Pistacia lentiscus and Pistacia atlantica of the Anacardiaceae family in the Tlemcen region by molecular modeling methods to inhibition of the enzyme α-amylase which is a digestive enzyme of Dociostaurus maroccanus using phenolics compounds derived from essentiels oil of aromatic plants: Elemol; Spathulenol; Myrcene; Beta- myrcene; Terpinen-4-ol; Bornyl acetate. Elemol give the best docking score, its interactions with α-amylase has the lowest energy score compared to the other complexes.
