Due to the absence of the ethnic data and studies of racial characterizations of this species in Algeria, which is an endangered species, we contributed to the phenotypical study of donkey population in the area of Tlemcen. A manpower of 61 adult asses, distributed on the level of two areas from where 11 body measurements and 06 phenotypical characters were retained for this study. Measurements LTC, HG, TP, LH, LE, PC, LoT, LoO, LQ, LaT and TM are respectively of 157,26±12,88; 116,16±7,23; 124,26±7,03; 37,15±3,21; 27,07±3,27; 17,50±1,86; 52,39±4,06; 30,15±2,19; 41,42±5,76; 23,01±2,06 and 46,24±4,16cm. the sex does not present any significant effect on studied body measurements (p>0,05). A factorial analysis of the multiple correspondences was carried out on the phenotypical characteristics, and it revealed two principal components which constitute 47,62% and 41,39% of total inertia, percentages respectively related to the color of the dress, the head, the members, the hairs, the muzzle and the belly .This analysis made it possible to establish remarkable phenotypical differences which have implications to take into account in the program of characterization and conservation of the species.

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.

The goal of this study is to characterize the diversity of the Algerian south donkey population, characterize its biometric variability, and determine the evolutionary relationships of this animal with its congeners at various latitudes. A total of sixty-six adult asses, distributed on the level of three wilayas from where eleven body measurements, six body indexes developed in horses and adapted to donkeys were calculated, and seven phenotypical characters were retained for this study. Measurements Lsi, HG, TP, LH, LE, Pc, LT, LO, LQ, LaT, Tm, Pv1, Pv2 are respectively: 98.05±10.46; 105.31±6.59; 188.88 ±8.61; 32.62±4.61; 27,17±4.41; 15.52±2.42; 50.92±3.82; 24.07±3.59; 39.24±14.30; 23.174±3.09; 41.82±3.52; 171.83±32.76; 145.83±27.62. Those information are used to compute 6 body indexes. According to body and profile indexes we deduce that our animals were medial linear and small (PI ≈ 1,08 and BI ≈ 0,82), they could not even bear their own weight loads (CI > 1), their heads were long (HI ≈ 0,45< 1) with a square body shape (LI ≈ 0,93< 1,10). Donkeys’ thoracic development was average according to (CD≈ 1,13). All parameters except the LE, PC, TM for the regions showed a significant difference on examined body measurements (p>0,05). On the phenotypical characteristics, a factorial analysis of the multiple correspondences revealed two main components that account for 48,90 and 44,26 % of total inertia, or 93,2 %. These percentages are related to the dress color, the head, the members, the hairs, the muzzle, and the belly. This research revealed significant phenotypic differences that should be included in the specie’s characterization and conservation efforts.

The "Sloughi" is a North African sighthound that the World Canine Organization recognizes as a Moroccan greyhound (breed standard n 188). The aim of this study is to compare the distribution of the body measurements of the Algerian sighthound by sex, sampling zones and body coat color. Sixteen morphometric variables were measured and six indices were estimated (format, massiveness, bone, head/neck, muzzle/head, withers/rump) in 30 adult unrelated animals (21 males and 9 females). The impact of sex on variables and indices was assessed using the t-test, while that of the sampling zones and that of the coat color using ANOVA. The mean values for withers height, height at rump, head length, muzzle length, ears length, neck length, body length, tail length, muzzle circumference, head circumference, neck circumference, chest circumference, waist circumference, thigh circumference, forearm circumference, wrist circumference were 71.85, 70.61, 25.24, 10.83, 13.16, 21.23, 68.44, 43.55, 21.50, 33.63, 41.27, 73.35, 48.73, 34.48, 14.67 and 10.81 cm, respectively. The results showed that there was no sexual dimorphism according to the phenotypic traits, the difference between the animals was only due to their body measurements. Males had more developed measurable traits than females, and the mean of Shannon’s diversity index for all variables was 0.99363

Dans le cadre de la caractérisation et de la valorisation du laurier noble en Algérie, nous avons entrepris des prospections et des collectes de matériel végétal à travers les wilayas de Tlemcen, Saïda, Alger et Chlef. Une caractérisation morphométrique a été réalisée sur les principaux caractères morphologiques notés sur les arbres et les feuilles, des analyses de variances, l'ACP et la corrélation de Pearson ont montré quelques différences entre les individus des quatre régions à travers ces caractères quantitatifs et qualitatifs. Les analyses de sol ont montré une certaine ressemblance dans les propriétés physiques et chimiques. L'extraction des huiles essentielles nous a donné des rendements variables et les analyses physico-chimiques de ces huiles ont montré des résultats presque identiques pour tous les échantillons.
