In this study, we evaluated the chemical composition and antibacterial activity of the methanolic and aqueous extracts of Eucalyptus blakelyi and Eucalyptus cladocalyx leaves collected from Bainem (Algeria). The phytochemical screening results showed that both extracts of these species contained tannins, flavonoids, quinones, coumarines, glycosides, and anthraquinones, in addition to these, methanolic extract was found to contain saponins and alkaloids. Antibacterial activity of the leaf extracts was evaluated against seven bacterial strains. E. blakelyi methanolic and aqueous extracts inhibited the growth of the majority of bacterial strains with significant inhibition against Bacillus subtilis (19.56 mm and 15.13 mm respectively). E. cladocalyx methanolic extract had good inhibitory activity against Micrococcus luteus (14.33 mm). Based on these results, E. blakelyi could be used as a significant source for the secondary metabolites with interesting medicinal properties.

In the current work, we present a phytocenological study of the phytocoenoses of the association Hieracio rotundati-Fagetum (Vida 1963) Täuber 1987 (Synonyms: Hieracio transsilvanico – Luzulo - Fagetum Vida 1963), identified in the acidophilic beech forests in the northern part of the Semenic Mountains, located in the southwestern part of Romania. The characterization of the analyzed association, as well as the presentation of the synthetic table, were carried out by selecting the most representative releves conducted in the Luzulo-Fagetum type beech forests belonging to the Semenic Mountains. The biodiversity study of this phytocoenosis was analyzed in terms of physiognomy, floristic composition, spectrum of life forms, floristic elements, the influence of ecological indices, soil moisture, temperature, soil chemical reaction, and karyological spectrum.

The camel milk sector is still little explored and especially the effect of the camel breeding system on certain properties and chemical compositions of camel milk. This study aims to assess the potential impact of the transition in the camel breeding system on milk productivity and the physicochemical composition of camel milk. To achieve this objective, a preliminary survey was conducted involving several breeders actively practicing the two targeted breeding systems (extensive and semi-intensive) in Algeria. This survey revealed milk production levels of 2 L/d and 3.5 L/d for the extensive and semi-intensive systems, respectively. Physicochemical analyses of these two types of camel milk (from extensive and semi-intensive breeding) were carried out. Various parameters were measured, including pH, acidity, density, total solids, solids-not-fat, ash levels, lactose, calcium, vitamin C, total proteins, whey proteins, and caseins. The results of these analyses indicate that the transition from extensive breeding system to the semi-intensive system significantly impacts the physicochemical quality of camel milk. Specifically, camel milk from the semi-intensive breeding system becomes less dense, more acidic and less rich in total dry matter particularly in solids-not-fat, which includes lactose, vitamin C, and minerals and notably calcium. Furthermore, this milk has become richer in proteins both total proteins and whey proteins, and more notably in caseins.

In spite of their multiple roles, little emphases have been given to indigenous forage legumes in Ethiopia. A study was undertaken at Wondo genet field gene bank to evaluate 15 accessions of Alysicarous rugosus for their nutritive values and agro - morphological characteristics. A randomized complete block design with three replications of treatment was employed on a pot size of 1m x 2m. The result showed that days to 50 % flowering, number of plants at 4 weeks and plants height varied among accessions (P < 0.001 and P < 0.05, respectively). The value of crude protein (CP) accession of 8652 and 7772 was significantly higher (P < 0.05) than that of 7752. The highest (P < 0.05) acid detergent fiber (ADF) value (35.49 %) was from accession 7752. Metabolizable energy (ME) was highest (P < 0.05) in 10021 than 9767, 7752, 13782 and 13508 accessions. In vitro dry matter digestibility (IVOMD) was high (P < 0.05) in 7704 than 13782. The hierarchical cluster analysis indicated the existence of a significant variability in nutritive values among the Alysicarpus rugosus accessions which suggest the need for further selection among accessions. Generally, the results indicated that these accessions of Alycarpus rugosus could be used as alternative sources of proteins in livestock feeding to supplement a basal diet of predominantly low-quality origin.

This research was carried out in the Ain Sefra region of Algeria’s southwest. Satellite data monitored steppe rangelands’ spatiotemporal evolution and land cover dynamics. A diachronic analysis based on supervised classification using the modified soil-adjusted vegetation index (MSAVI2) was applied. Two Landsat satellite images (ETM+ 2000 and OLI 2022) taken at 22-year intervals were used to map and assess changes in vegetation cover. The findings point to a regressive evolution of vegetation cover. The main causes of severe rangeland degradation are overgrazing, prolonged drought, and wind erosion. However, implementing a strategy to rehabilitate and conserve pastoral resources has positively impacted species’ biological recovery and flora richness. Geomatics has significantly contributed to this study as a tool for assessing and monitoring natural resources. MSAVI2 is a dependable and effective index for assessing the state of vegetation in arid to semi-arid regions.

Sunlight plays an essential role for our well-being, as it provides us with Vitamin D and a sense of relaxation, but on the contrary, various studies have already demonstrated the harmful effects of uncontrolled and exaggerated exposure to the sun. Studies have shown some of the side effects of exaggerated sun exposure such as skin inflammation, the appearance of free radicals with an oxidative effect on proteins and dermal lipids, damage to skin cell DNA and skin immune function. In the present paper, we have carried out a clinical study on premature aging as a result of exaggerated and uncontrolled exposure to the sun. The experimental plan is based on the observational and interview method, but also on measurements with the help of a device called Sunsor meter, which highlights the intensity of solar erythema according to the time of exposure to the sun. The research findings revealed the detrimental consequences associated with premature photoaging of the skin, with a positive correlation observed between the duration of exposure and the severity of these effects.

Despite their nutritional value, children often reject vegetables. Parenting styles may influence children’s dietary behavior. This study aims to assess the influence of parenting styles on the rejection and frequency of consumption of commonly consumed vegetables in today’s Algerian society. The survey involved 70 children aged 5 - 10 years and their mothers. A questionnaire collected data on vegetable rejection with a list of 18 vegetables. Two other questionnaires were used, the first to estimate the frequency of vegetable consumption among the children and the second to study parenting style. The results indicate that children enjoy most vegetables (73.68 %). Carrot and tomato are the most popular vegetables, while the most rejected vegetables are cardoon and onion. The least consumed vegetables are the most rejected. Moreover, it can be noted that children of authoritative parents consume more vegetables than those of authoritarian, indulgent and neglectful parents. Depending on the parenting style, some often rejected vegetables are appreciated. It appears that the high demandingness and sensitivity of the authoritative parents favor vegetable consumption. The level of demand and sensitivity of each parenting style may modulate the appreciation of vegetables.

Living on Bangladesh’s riverine islands (Char lands) puts one at the disadvantage of underdevelopment. Hence, this study focused on the sociodemographic peculiarities and livelihood practices of farmers in the Char lands of Bangladesh. Convergent mixed methods research design was adopted to generate the required data. The quantitative data were analyzed using Statistix 10 software, while the qualitative data were analyzed by collecting themes relative to the study objectives and describing them accordingly. Results revealed that, the sociodemographic peculiarities of the respondents were low and vulnerable, being majority illiterate, having small farm size on which they predominately depend, poor housing, and a population dominated by = 30 years old persons. The mean income (%) from on-farm livelihood practices was superior to that from off-farm livelihood practices, and a big proportion of the mean annual expenditure coverage was split between food and agricultural inputs/implements. Farm size contributes significantly to income, but, natural disaster, illiteracy, riverbank erosion, and lack of improved agriculture knowledge were the foremost livelihood problems in the Char lands. Consequently, the present study deduces that an all-inclusive masterplan is inevitable for sustainable development of the Bangladesh Char lands.

This study investigates Camelina sativa, an emerging oilseed crop with potential for food, feed, and sustainable farming. Conducted at the Agroveterinary Institute, University of Batna 1 in Algeria, during the growing season of 2021-2022, the experiment evaluated the impact of four irrigation treatments replicates four times (T0: rainfed, T1: 100 % of crop evapotranspiration ETc, T2: 75 % ETc, and T3: 35 % ETc) using a completely randomized block design. The results revealed various effects of water deficits on Camelina yield, quality, and water use efficiency (WUE). The highest seed yield (20.77 q ha-1 ) was obtained with T1 (total water applied 287.85 mm), while the lowest (6.62 q ha1 ) was observed with T0 (151.20 mm of rainfall). The T2 treatment (total water applied 253.688 mm) led to a 14 % reduction in seed yield compared to full irrigation while achieving significant water savings of 25 %, with the highest values of irrigation water use efficiency IWUE for both grains and biomass at 1,095 and 5.24 kg m-3 , respectively. Moreover, deficit irrigation had a positive impact on seed protein content, which showed a negative correlation (r = -0.92) with oil content and water supply, highlighting the adaptability of Camelina to produce much higher quality grain under water-restricted conditions. Integrating Camelina sativa with deficit irrigation offers a sustainable agricultural strategy, optimizing water resources and promoting drought-tolerant crops. This approach improves water use efficiency, builds resilience, and adapts to areas vulnerable to climate change, addressing the critical nexus of food security and water management.
