Comparison of Biochemical Compounds in Methanolic Extracts of Stem, Root, and Callus Tissues of San Pedro Cactus (Echinopsis pachanoi)

This study demonstrates that methanolic extracts from the stem tissues of San Pedro cactus contain significantly higher concentrations of bioactive compounds, including alkaloids, phenols, flavonoids, and antioxidants, compared to root and undifferentiated callus tissues, indicating that differentiated tissues are superior sources for these metabolites.

Field effectiveness and reproductive outcomes of Synchromate-based estrus synchronization and artificial insemination in smallholder dairy cattle in Gondar Zuria District, northwestern Ethiopia

This study in northwestern Ethiopia found that while a Synchromate-based estrus synchronization protocol is feasible for smallholder dairy systems, it yielded a modest 21.2% pregnancy rate, with success significantly influenced by body condition, breed, and the timing of the treatment response.

Bioprocessing of coconut husk to produce second-generation bioethanol using Zymomonas mobilis ZM4

This study demonstrates the feasibility of converting abundant coconut husk into second-generation bioethanol by employing an integrated strategy of sequential pretreatment, enzymatic hydrolysis, and fermentation using *Zymomonas mobilis* ZM4, which achieved a final ethanol yield of 0.0975 g per gram of biomass.

Diagnostic concordance and animal-level epidemiological patterns of bovine tuberculosis, paratuberculosis, and enzootic bovine leukemia in Colombian dairy cattle

A cross-sectional study of Colombian dairy cattle reveals high enzootic bovine leukemia prevalence but significant discordance between serological and molecular diagnostic methods, while finding no confirmed cases of bovine tuberculosis or paratuberculosis, thereby highlighting the need for integrated surveillance strategies and cautious interpretation of single-test results in endemic settings.

Modeling CPUE of the banana jellyfish (Catostylus perezi Ranson, 1945) using ensemble methods (GAM, RF, NN) and its association with physicochemical parameters in the northern Oman Sea

This study establishes the first scientific baseline for the banana jellyfish fishery in the northern Oman Sea by analyzing seasonal catch data and employing a superior ensemble model of GAM, RF, and NN to demonstrate that CPUE is significantly driven by physicochemical parameters, particularly temperature, pH, and dissolved oxygen, thereby highlighting the need for specialized stock assessment frameworks to ensure sustainable management.

Multivariate Assessment of Soil-Plant Relationships and Principal Component Structure in a Pongamia pinnata + Costus igneus Silvi-Medicinal System under Semi-Arid Alfisols

This study utilized multivariate analysis to demonstrate that while Integrated Nutrient Management (INM) treatments significantly influenced greenhouse gas emissions and the growth of the understorey *Costus igneus* in a semi-arid silvi-medicinal system, they had minimal impact on the *Pongamia pinnata* overstorey, thereby establishing a robust analytical framework for evaluating nutrient-growth-yield networks in such agroforestry settings.

Mapping of early blight (Alternaria solani) disease tolerance in Tomato (Solanum Lycopersicum L.) through QTL-Seq and expression analysis of defense-related genes

This study identifies five novel quantitative trait loci (QTLs) on chromosomes 2 and 6 governing early blight tolerance in tomato using QTL-Seq and confirms the critical role of specific defense-related genes within these regions through expression analysis.

Soil amelioration driven by diverse Herbaceous perennials cultivation: Responses of physicochemical properties, enzyme activities, and organic carbon

This study demonstrates that cultivating diverse herbaceous perennials in Northeast China significantly improves soil physicochemical properties, with *Pseudolysimachion spicatum* identified as the most effective species for enhancing soil aggregate stability, nitrogen availability, and microbial biomass carbon.
