    Analysis of the gut contents of largehead hairtail, Trichiurus lepturus (Linnaeus, 1758) in Surigao Del Sur
    Barros, Andrea Philine R. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)
    The traditional gut content analysis is one of the methods used which investigates feeding interactions, specifically those belonging to the aquatic food webs. The ribbonfish, Trichiurus lepturus is an economically important fish, and due to its high demand to other south-east Asian countries especially in the Philippines, there is a targeted fishery for this resource. However, the catch of this species in the country has declined recently. Since feeding habits are fundamental to understanding the ecology of a community, this study aimed to analyze the gut contents of Trichiurus lepturus. A total of 66 guts were examined in the study. The size ranged from 101-505 mm in total length. They fed mostly on fishes including Encrasicholina sp., and shrimps such as Acetes, Penaeus, and Lucifer. Moreover, there was an occurrence of cannibalism but only larger individuals. Microplastics were also evident in most of the size classes.

    Temporal variation in the subtidal macroinfaunal composition of a NaGISA seagrass bed in southern Guimaras, Philippines between 2015 and 2016
    Bacabac, Earl Jeroh I. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)
    Seagrass meadows are amongst the most abundant and diverse ecosystems when it comes to biodiversity but due to stress induced by natural and anthropogenic factors, a worldwide decline threatens the vital ecological functions of these habitats. Studying the infauna provides clues and information about the complexity of seagrass ecosystems and provides information that would facilitate better seagrass area management and associated conservation efforts. The NaGISA sampling protocol was conducted in Calaparan seagrass bed in TINMAR, Guimaras, Philippines between Sept. 2015 and 2016. Overall macrofaunal density was recorded at 21,954.80 ± 36,109.62 ind.m'2 with macrofaunal density higher in 2015 than in 2016 albeit, insignificant except for capitellid polychaetes. Community structure analysis also found similarity in dominance patterns in the subtidal zone with other soft-bottom macrofaunal studies in the Philippines with polychaetes, nematodes, and crustaceans as the respective dominant macrofaunal groups observed. Dominant polychaete families were also found to be cosmopolitan and opportunistic. Granulometric analysis characterized the sediment as pebble to medium sand with mid phi values ranging from -3.69 to 1.10 but poor sorting in all sampling points was observed. Cymodoceaceans dominated the subtidal zone in both years (Halodule pinnifolia in 2015; Cymodocea rotundata in 2016). Correlation analysis showed macrofaunal densities to have a significantly strong negative relationship with sorting index and percent gravel while a strong positive relationship with percent seagrass cover. The poor sediment sorting, coarse sediment character, and seagrass cover were the primary factors influencing the observed decrease in macrofaunal density but the decrease is considered normal for the variability of macrofauna in the area. A clearer picture of macrofaunal interactions would be provided with comparison to intertidal macrofauna of the area in the sampling years and data on additional factors that were not measured in the study.

    Sagip COUGHamilya: Improving prevention, and case management & care seeking in Sitio Durog, Barangay Palaca, Miagao
    Asorio, Leslie S.; Clarito, Thea Joy A.; Dolorosa, Rex Victor V.; Marecap, Mitzi N.; Napulan, Andrea Marie N.; Recabar, James Mathew V.; Rodriguez, Sael D.; Velasco, Princess Monic Q. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2019-06)
    According to the 2018 Morbidity Diseases Reports of Miag-ao’s Rural Health Unit (RHU), Acute Respiratory Infection (ARI) is the main cause of morbidity among the children in the municipality. Upon further review, the community that was found to have the greatest number of ARI cases is that of Barangay Palaca. To contribute with the reduction of ARI cases in the said community, Project Sagip COUGHamilya was implemented in Sitio Durog. This project aims to reduce the number of current ARI cases among children aging 2 months to 11 years old by at least 50% after the 6-week project implementation. In order to accomplish such goal, the team utilized strategic components such as: (1) establishment of a core group called FamiLEADERS, (2) honing the ARI case management knowledge and skills of the barangay health workers (BHWs) through FamiLINANG sessions for BHWs, (3) improving the mothers’ & guardians’ knowledge, attitude, and practices (KAP) towards care seeking and case management for ARI through FamiLINANG sessions for mothers, and (4) raising the children’s awareness on cough etiquette, proper handwashing, and other key health practices through LINIStorya sessions. Upon implementation, the project’s outputs include the 80% increase in the ARI case management knowledge and skills of BHWs, 44.47% increase in the KAP of the mothers & guardians towards care seeking and case management for ARI, and 12.5% increase in the children’s awareness towards cough etiquette, proper handwashing, and other key health practices. All these results were statistically found to be significant improvements. In conclusion, the strategies done by the group significantly improved the care seeking, case management, and key health practices for ARI in Sitio Durog, Barangay Palaca. As a result, Projesct Sagip COUGHamilya contributed to the reduction of ARI cases by 80%, far exceeding the goal of the project and deeming it to be very effective and successful.

    Knowledge, attitudes, and practices on dengue vectors of households in Tumagboc Catchment Area, Miagao, Iloilo
    Arbizo, Jeric L.; Baldevarona, Rosa Lea S.; Caoyonan, Louise Asuncion D.; Gabasa, Marah Febcy J.; Mapa, Fernie Love D.; Patria, Elaine Joy M.; Tenchavez, Darlene Ruth B.; Trivilegio, Enna Fleur C. (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2011-03)
    Previous studies have shown that knowledge, attitudes and practices have an association with the dengue vector control. As such, the independence of mosquito population on the sociodemographic characteristics and KAP of the household heads in Tumagboc Catchment Area, Miagao, Iloilo was tested. Based on the results, the household heads generally are unemployed, married females aging 41 to 50. Their households are composed of 4 to 7 members with no or one child below 15 years, and usually receive below P 1999 per month. Most of them are informed about dengue fever, but only one had suffered from it in the last two years. Moreover, they have moderate knowledge, poor attitudes, but good practices regarding dengue prevention. The container index is 2.71 for crude mosquito larvae and pupae population, and 0.39 for Aedes sp. The house index is 9.72, while the Breteaux indexis 13.19. Chi-square analysis at 0.05 level of significance confirmed the independence of mosquito larvae and pupae population from monthly income, dengue information reception, knowledge, attitudes and practices. A solid reason was the untimely conduct of the study in the beginning of the summer season, when stagnant water has dried up and with few vulnerable breeding sites.

    Risk zone mapping of 2010 dengue fever and dengue hemorrhagic fever cases in the Province of Iloilo based on land cover
    Andrada, Thresdale; Cañonero, Gertrude Mikee; España, Regine Marie; Puno, Abigail; Sarangaya, Dorothy Rose; Tan, Leonard; Tejada, Ma. Corazon (Division of Biological Sciences, College of Arts and Sciences, University of the Philippines Visayas, 2013-04)
    Dengue is considered as one of the most important vector-borne diseases in many tropical and subtropical countries. Iloilo Province had 8201 cases in 2010. Heterogeneity in the risk of disease transmission results from spatial heterogeneity in both land use and land cover. Thus, the present study was conducted to identify the risk zones of Dengue Fever and Dengue Hemorrhagic Fever in Province of Iloilo in 2010 based on land cover types by using GIS software. Results of the study show that all land covers in the 6th district pose moderately low risk on dengue incidence. In the case of the 1st district of Iloilo, on the other hand, water bodies have the highest probability of dengue incidence, while the rest of the districts (2nd, 3rd, 4th, 5th). built-up areas have the highest probability of dengue incidence. The land cover type in Iloilo, therefore, with the highest risk for dengue incidence are built up areas due to its high population density, multitude of households and stagnant water areas.
