Abstract Microplastic pollution threatens marine ecosystems and human health through seafood consumption in the Philippines. This study assessed the prevalence, abundance, and morphology of microplastics in the gastrointestinal tracts of Indian squid (Uroteuthis duvaucelii) from two major Bureau of Fisheries and Aquatic Resources – National Stock Assessment Program (BFAR-NSAP) landing sites in…

Abstract Protein glycosylation is a covalent attachment of complex oligosaccharides to proteins and lipids, is a ubiquitous and essential post-translational modification (PTM) that significantly expands the functional diversity of the proteome. While fundamental to processes such as protein folding, trafficking, and signal transduction, disruptions in normal glycosylation are increasingly…

Abstract This study evaluated the curriculum alignment, accuracy, and readability of the instructional material titled Environmental Disaster, Sanitation, and Waste Management. The research aimed to assess whether the content aligns with prescribed educational standards, verify the accuracy of the information presented, and determine the readability level of the text. Using a mixed-method…

Abstract Coral reef monitoring is essential for guiding local conservation strategies, particularly in areas exposed to increasing human pressures. This study assessed reef condition in six Marine Protected Areas (MPAs) along Illana Bay, Zamboanga del Sur, southern Philippines, to establish baseline ecological indicators for management. SCUBA-based photo-quadrat surveys were conducted, and…

Abstract Global warming strongly influences the development of Zeugodacus cucurbitae, a major pest of cucurbit crops; however, the effects of certain intermediate and high temperatures, as well as natural conditions particularly on watermelon remain insufficiently documented. The present study assessed the effect of a thermal gradient, including ambient temperature and constant temperatures of…

Abstract Kamettia caryophyllata (Roxb.) Nicolson & Suresh, an endemic climber, has been traditionally used in various medicinal preparations, yet its phytochemical and pharmacological properties remain insufficiently explored. The present study aimed to investigate the phytochemical composition and biological activities of the methanolic fruit extract of K. caryophyllata. Preliminary…

Abstract Purple corn is used to prepare many popular dishes. This study involved physicochemical and microbiological analyses of purple flour samples. The aim was to improve the sanitary quality of this popular flour. A total of 71 samples, each weighing approximately 250 g, were collected from fifteen randomly selected vendors at the main market in Katiola (8° 8′ 26.002“ N, 5° 6′ 7.999“ W). The…

Abstract Murraya koenigii L., a medicinal plant utilized in traditional folk medicine, possesses anti-diabetic, anti-microbial, anti-inflammatory attributes and also is widely used for the treatment of hemorrhoids, itching, leukoderma, and hematological disorders. From the present work, total 8 fatty acids were identified by Gas Chromatography–Mass PSpectrometry (GC-MS) technique where the level…

Abstract Banana production plays a vital role in the agricultural economy of tropical countries such as the Philippines, where maintaining crop health is essential for sustaining yield and ensuring farmer livelihoods. Nutrient deficiencies in banana leaves, often manifested through discoloration, leaf deformation, or necrosis, pose challenges to timely diagnosis, especially for smallholder…

Abstract African swine fever (ASF) is a highly contagious hemorrhagic viral disease of domestic and wild pigs, which is responsible for serious economic and production losses. It is caused by a large DNA virus of the Asfarviridae family.  The study was conducted to determine positive   cases of African swine fever on pigs from different slaughterhouses in municipalities of second district in…

Abstract The Poro region is home to several natural habitats for frogs, and their consumption has become widespread in this part of northern Côte d’Ivoire. Frog harvesting has become a significant source of income and food for those involved in this sector. This activity is not subject to any regulatory framework, and this could lead to the extinction of the resource if no action is taken by the…

Abstract Volvariella volvacea (paddy straw mushroom) is an important edible mushroom cultivated widely in tropical and subtropical regions due to its rapid growth, nutritional value, and medicinal properties. The present study investigated spawn preparation and cultivation of V. volvacea using paddy straw as the primary substrate. Pure cultures were established under controlled laboratory…

Abstract DNA barcoding utilizing the cytochrome c oxidase subunit I (COI) gene was employed to identify the cave-dwelling bats in Tabaco cave, Sta. Teresita, Cagayan, Philippines, an unexplored site for molecular bat research. This study integrated preliminary morphological classification with confirmatory COI barcoding to identify species within this understudied assemblage. Three species from…

Abstract This study assessed the species composition, diversity, and conservation status of ferns (Pteridophyta) in Barangay New Casul, Mutia, Zamboanga del Norte. Three 10 × 10-meter quadrats were established across distinct microhabitats, and ferns were identified using morphological and taxonomic references. A total of sixteen fern species from nine families were recorded, representing both…

Abstract Cucumis sativus L. plant cultivated in open and covered conditions in the Republic of Azerbaijan, was studied for phytopathogenic fungal biota. It has been determined that a total of 15 fungal species are involved in the formation of the phytopathogenic mycobiota of cucumber plants. Although more than half of the recorded fungi showed phytopathogenic properties in both conditions,…

Abstract The emergence of multidrug-resistant (MDR) Salmonella enterica in poultry production systems poses a significant threat to animal health, food safety, and public health worldwide. This study investigated the occurrence, antimicrobial resistance patterns, and molecular identity of zoonotic Salmonella spp. isolated from poultry environments in Bangladesh. A total of 60 samples, including…

Abstract This study evaluated the land-use efficiency of sweet corn–cowpea intercropping, influenced by planting dates and fertilizer application methods, in Tupi, South Cotabato, Philippines, from March to June 2025. Using a randomized complete block design with factorial treatments, the study assessed growth and yield parameters of sweet corn and cowpea across varying planting intervals and…
