Here is an ethnobotanical study on halophytic plants with medicinal virtues traditionally used by the populations surrounding the Macta wetland (north-western Algeria). An ethnobotanical survey was carried out and the data collected were statistically analyzed by using the R software and 150 questionnaire sheets. The results obtained allowed the identification of 53 plants including 32 halophytic species with medicinal virtues belonging to 28 genera and 17 botanical families. On the basis of the ethnobotanical survey, we identified 43.75% of the species that are used as anti-inflammatory, 28% to treat diuretic disorders, 21.87% to treat uro-genital disorders, 18.75% for their effects on the digestive system, and 15% of the plants which are used against diabetes. Multifactorial analysis reveals a good correspondence between the ethnobotanical aspect of plant species and their therapeutic uses. The results obtained indicate the appearance of five typical use profiles specific to medicinal virtues.

The chickpea is a very important food species in Algeria whose cultivated type is Kabuli and it is the one of the largest seed legumes. Ten chickpea genotypes were characterized for different agro-morphological traits in order to estimate the genetic diversity. For this purpose, an experimental culture test (completely randomized block system) was conducted at the pilot farm of El Hamaddouche in Tlemcen. Analysis of variance showed a high level of significance for many traits. The Shannon and Weaver index H' (mean) of this collection (0.29) reflects a weak morphological diversity. The principal component analysis (PCA) was performed for all traits and explained 60.43% of the total variability. The genotypes were grouped into five clusters by reference to the chosen axes. Genotypes forming the same group are closely related to each other according to their common agro-morphological traits, the same pattern was observed for the Hierarchical Ascendent Classification (HAC). Cluster analysis and correspondence analysis summarizes that there is a close resemblance between genotypes from different regions, implying that there are no relationships between geographic origins and genetic diversity.

Cowpea coat color is a consumer-related trait that determines consumer preference and acceptability of the commodity in the market. Understanding the mode of inheritance of seed coat color will assist in choosing appropriate breeding technique in developing desirable cowpea varieties. This study was conducted to confirm the specific mode of inheritance of seed coat color in cowpea. Three bi-parental crosses using five different varieties of cowpea with contrasting seed coat colors were carried out to obtain F1 seeds at the Greenhouse, Faculty of Agriculture, Obafemi Awolowo University, Ile – Ife, Nigeria. The F1s were advanced to obtain F2 segregating populations which were evaluated by visual observation and the seeds were categorized into different distinct groups. The observed seeds of the F2 population of all the three crosses deviated extremely from Mendelian monogenic inheritance ratio in different degrees. TVu4669 × TVu43 segregated into two color groups resulting in brown mottled (15.4 %) and black mottled (84.6 %). Ife Brown × TVnu699 segregated transgressively into five distinct groups of colors giving rise to brown (51.4%), black (23.7%), grey (14.8%), red (5.3%) and speckled (4.8% ); while Ife Brown × TVu2723 segregated into three color groups involving mottled black (4.3%), black (85.1%) and speckle (10.6%) coat colors. It could be inferred that more than one gene controls the inheritance of the seed coat color in cowpea, which implies that the trait is polygenic. It is recommended that molecular genetics’ techniques be explored in order to have better understanding of the mode of inheritance of seed coat color in cowpea.
豇豆毛色是一种与消费者相关的特征，它决定了消费者对市场上商品的偏好和接受程度。了解种皮颜色的遗传模式，有助于选择合适的育种技术，培育理想的豇豆品种。本研究旨在确定豇豆种皮颜色遗传的具体模式。在尼日利亚Ile - Ife的Obafemi Awolowo大学农学院的温室中，使用五种不同的豇豆品种进行了三次双亲本杂交，获得了F1种子。将f15推进得到F2个分离群体，通过目测对其进行评价，并将种子划分为不同的群体。3个杂交组合F2群体的种子均不同程度地偏离孟德尔单基因遗传比。TVu4669 × TVu43分为棕色斑驳(15.4%)和黑色斑驳(84.6%)两个颜色组。Ife Brown × TVnu699有5种不同的颜色，分别是棕色(51.4%)、黑色(23.7%)、灰色(14.8%)、红色(5.3%)和斑点色(4.8%);而Ife Brown × TVu2723分为三个颜色组，包括斑驳黑色(4.3%)，黑色(85.1%)和斑点(10.6%)的毛色。由此可以推断，豇豆种皮颜色的遗传受多个基因的控制，表明该性状具有多基因性。为了更好地了解豇豆种皮颜色的遗传模式，建议进一步探索分子遗传学技术。

Legume seeds are known to be a source of protein, vitamins, essential organic minerals and fatty acids. Their high protein content makes them a valuable natural and inexpensive alternative to the soybean. Seeds fatty acids of genotypes belonging to nine Vicia L. taxa collected in Algeria were extracted by Soxhlet and their composition was determined by Gas Chromatography coupled with FIame Ionization Detection (GC-FID). In order to assess phylogenetic relationships between taxa on intra and interspecific levels, fatty acids profiles were used as a chemotaxonomic marker. Oil yields were between 0.67 and 2.40%. A total of 27 fatty acids were identified, varying from 9 to 20 compounds. The proportion of unsaturated fatty acids varies from 70.67 to 91.749% where the linloleic acid is predominant. While the saturated fatty acids content is between 8.60 and 29.33% with the predominance of palmitic acid. Our results demonstrate the quality of the genotypes, which contain fatty acids of great nutritional interests. Indeed, Omega 3- fatty acids, which rate can reach 12.187% in our taxa, are Poly UnSaturated Fatty Acids associated with many health benefits, such us cardiovascular ones. Indeed, the results demonstrate the nutritional quality of obtained oils and opens up perspectives to explore other compounds. Finally, the hierarchical classification revealed two major clusters where the taxonomic boundaries of the genus are well defined at subgeneric and sectional levels. It is also an important step to suggest the species as a new industrial crop for the animal feed and production of proteins and oils widely used in food industries

Inflammation is an immune response to chemical, physical or biological aggression. The comprehension of the several pro-inflammatory and pro-resolving process may lead to the development of new functional drugs instead of the conventional ones. However, Inflammation reaction is conventionally treated by steroidal and nonsteroidal anti-inflammatory drugs. These medications may be useless because of their side effects. In this study, we aim to evaluate the anti-inflammatory and analgesic effect of alkaloid /fixed oil mixture (AO) from flaxseeds in-vivo. Three doses of AO mix (50, 100 and 200 mg/kg) were used in several anti-inflammatory and analgesic tests. The obtained results had shown that the AO mix presents a potential anti-inflammatory and analgesic activities. These results highlight the therapeutic potential of alkaloids and fixed oils combination. Additionally, to other research, the present study supports the anti-inflammatory and analgesic effects of flax seeds with an original contribution by combining alkaloids and fixed oil from Linumusitatissimum

Evaluation of medicinal plants for their antidiabetic activities has increased considerably around the world as well as in Algeria. Olea europaea var. sylvestris, commonly called Ezzeboudj, is traditionally used by Tlemcen population in Algeria, for treating diabetes mellitus. In this work, we studied the antioxidant activity of wild olive leaves crude extracts, by free radical DPPH scavenging method and iron reduction FRAP. On the other hand, evaluation of the ability of the extracts to inhibit α-amylase activity. The qualitative phytochemical screening carried out on O. europaea var. sylvestris leaves extracts showed the presence of tannins, sterols and triterpenes, saponins, flavonoids and terpenoids. A quantitative analysis of the crude extracts showed significant levels of total polyphenols and flavonoids in hydroacetonic extract, with an amount of 228,45 ± 0,03 mg GAE /g and 204,8 ± 0,04 mg CE /g, respectively. The results obtained from the antioxidant activity showed a high scavenging activity for hydroacetonic extract with an IC50 of 7,95 ± 0,16 µg/ml. In vitro tests carried out on the inhibitory of α-amylase activity, revealed an inhibitory effects, specifically with hydromethanolic extract in a concetration-dependent manner, with an IC50 value of 0,91 ± 0,02 mg/ml. These findings reveals that O. europaea var. sylvestris leaves could represent an interesting source of antioxidants and allow to the development of new antidiabetic agents.
对药用植物抗糖尿病活性的评价在世界各地以及阿尔及利亚都大大增加。油橄榄(Olea europaea var. sylvestris)，俗称Ezzeboudj，传统上被阿尔及利亚特莱姆森人用于治疗糖尿病。本文采用自由基DPPH清除法和铁还原FRAP法研究了野生橄榄叶粗提物的抗氧化活性。另一方面，评价了提取物抑制α-淀粉酶活性的能力。对木犀叶提取物进行了定性植物化学筛选，结果表明木犀叶提取物中含有单宁、甾醇和三萜、皂苷、黄酮类化合物和萜类化合物。对粗提物进行定量分析，发现氢丙酮提取物中总多酚和总黄酮含量显著，分别为228、45±0.03 mg GAE /g和204、8±0.04 mg CE /g。抗氧化活性结果表明，对氢丙酮提取物具有较高的清除率，IC50为7.95±0.16µg/ml。体外α-淀粉酶活性抑制实验表明，乙醇提取物对α-淀粉酶有一定的抑制作用，其IC50值为0.91±0.02 mg/ml，且呈浓度依赖性。这些发现表明，欧陆叶可能是一种有趣的抗氧化剂来源，并允许开发新的抗糖尿病药物。

Mediterranean ecosystems are subject to the influence of particular climatic conditions characterized by scarcity or irregular rainfall and long dry summer periods. These climatic restrictions generally disturb the vegetation. In order to overcome these problems. The use of pioneer tree species, adapted to climatic hazards, remains the most recommended solution. The carob tree (C.siliqua) is an agro-sylvo-pastoral species with enormous socio-economic and ecological interests. This Mediterranean tree is favourably established in semi-arid and arid areas. For the success of reforestation projects, the management and preservation of this species requires prior assessment and characterization of their variability. This approach is based on multidisciplinary studies involving the analysis of the diversity of agro-morphological, adaptive traits. In this context, the present study aims to explore, using agro-morpho-metric markers of the carob tree in central and north-western Algeria. We use the pods and leaves to identify, label or characterize the different collections or germplasm of the carob tree in the world. This study was carried out on the variability of nine morpho-metric traits related to fruits (pods) and leaves through a comparative study at the level of provenances (Larabaa, BordjBounaama, Aflou, Remchi and Ain Sefra). Carob plants from three contrasting ecotypes of Ceratoniasiliqua (Remchi ecotype from the sub-humid stage, Tissemsilt and BordjBounaama ecotype from the semi-arid stage and Ain Sefra and Aflou ecotype from the arid stage) were subjected to a thorough biometric study of the leaves and pods collected after a field survey in June-July 2013. The results showed the highest mean values for the majority of the traits studied, thus indicating the importance of the provenance factor. Based on the analyses of variance and their decomposition, and depending on the biometric traits studied, the carob resource management strategy can be chosen either for the pod factor (pod weight, pod length, number of seeds per pod and number of infested seeds per pod) or the leaf factor (petiole length and leaf area). In the case of our collections, the longest size was recorded in the Bordj Bounaama population (16.66 cm ± 2.36) and Remchi (16.10 cm ± 2.78) and the smallest in the Aflou population (9.40 cm ± 1, 27). Indeed, a positive correlation between the measured parameters (length, width, thickness and weight of the pod) was observed. Differences between ecotypes were observed for all morphological traits studied.

The novel concept of behavioural instability has proven suitable for studying the behavior and personality in zoo animals. Individual personality has an impact on how the zoo best perform environmental enrichment, and behavioural diversity of captive populations intended to potentially repopulate wild habitats. This study aims to prove the presence of recognizable personalities in Rothschild giraffes (Giraffa camelopardalis rothschildi), as well as to investigate whether visitor numbers affect the behavioural expressions in this species. Six giraffes (bot young and adults) were filmed in Aalborg Zoo, and the recordings were subsequently analysed. The procured data was then analysed using a series of tests primarily focusing on behavioural reaction norms. The results shows that distinct personalities exist within the groups of Rothschild giraffes. However, the number of visitors exhibited no statistical significance upon the behaviour of the individuals. It can thereby be concluded that specimens of Rothschild giraffes possess unique personality traits which are worth defining in order to ensure behavioural diversity.

It can thereby be concluded that specimens of Rothschild giraffes possess unique personality traits which are worth defining in order to ensure behavioural diversity.","PeriodicalId":12670,"journal":{"name":"GABJ","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83940230","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 growth curve in poultry is important to evaluate the performance and farming management system. This study was aimed to estimate the growth curve of body weight in goose. The growth curve in this study was estimated with non-linear Gompertz model through CurveExpert 1.4. software. Three goose breeds in Slovakia i.e. Landes (L), Pomeranian (P) and Steinbacher (S) were used in this study. Total of 28 geese (10 L, 8 P and 10 S) were used to estimate the growth curve. Research showed that the asymptotic weight (A) in those geese were reached at 5332.51 g (L), 6186.14 g (P) and 5048.27 g (S). Thus, the maturing rate (k) in each breed were similar (0.05 g/day). The weight of inflection was reached at 1960.48 g (L), 2274.32 g (P) and 1855.98 g (S) respectively. The time of inflection (ti) was reached at 25.6 days (L), 26.2 days (P) and 27.80 days (S) respectively. The maximum growth rate (MGR) was reached at 98.02 g/day (L), 113.72 g/day (P) and 92.80 g/day (S). According to the CurveExpert 1.4. software, the coefficient of determination (R2) with Gompertz model was 0.99 for each breed. It can be concluded that Pomeranian geese had highest of growth rate than the other breeds.
家禽生长曲线是评价家禽生产性能和饲养管理制度的重要依据。本研究旨在估计鹅体质量的生长曲线。本研究的生长曲线采用非线性Gompertz模型，通过CurveExpert 1.4进行估计。软件本研究选用斯洛伐克的三个鹅品种，即朗德鹅(L)、波美拉尼亚鹅(P)和施泰因巴赫鹅(S)。选用28只鹅(10只L、8只P、10只S)进行生长曲线估计。研究表明，各品种鹅的渐近体重(A)分别为5332.51 g (L)、6186.14 g (P)和5048.27 g (S)，各品种的成熟率(k)相近(0.05 g/d)。挠曲重量分别为1960.48 g (L)、2274.32 g (P)和1855.98 g (S)。时间分别为25.6 d (L)、26.2 d (P)和27.80 d (S)。最大生长速率(MGR)达到98.02 g/d (L)， 113.72 g/d (P)和92.80 g/d (S)。用Gompertz模型对各品种的决定系数R2均为0.99。由此可见，波美拉尼亚鹅的生长率高于其他品种。

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
