No full textBackground: Coconut Leaf Beetle Brontispa longgisima Gestro, 1885 is an economically significant pest that is not yet fully understood. Studying patterned variations of the left and right side parts or asymmetry of Brontispa longgisima could give us a picture of its mode of adaptation to different environments and its success as a pest, the ability to maintain developmental homeostasis. Objective: This study aimed to evaluate and quantify left and right variation patterns of Brontispa longgisima hind wings using the advanced geometric morphometric tool -Symmetry and Asymmetry in Geometric Data (SAGE). Results: Procrustes Analysis of Variance (ANOVA) revealed that individual variation and directional asymmetry were present in male and female populations in all sampling locations for wing shape and size, although slight fluctuating asymmetry was noted. Principal component analysis also showed that the movements of landmarks were localized only to landmarks 3, 4 and 14. Conclusion: Based on the results of this study, Brontispa longgisima hind wings have undergone lesser environmental or genetic perturbations because of the presence of directional asymmetry which by far, is genetically controlled. But based on individual variations of metasternum and wings, B. longissima is able to counterbalance the external pressures evidenced by shape variability of the studied traits
Species composition, diversity and community structure of mangroves in Barangay Fabio, Tagana-an, Surigao Del Norte, Philippines
No full text<p>Mangrove ecosystems serve a crucial environmental role in protecting coastlines from storms, floods, and erosion, and they aid as a breeding ground for many marine life. Mangrove forests are declining due to relentless anthropogenic activities. Thus, the assessment of mangrove species plays a crucial part in the upkeep and protection of the forest. This study aimed to determine species composition, diversity, and community structure of mangrove forests in Barangay. Fabio, Surigao del Norte using the line quadrat method. Results revealed that the area has very low diversity belonging to only three families, three genera, and three different species. Among the three other species, <i>Rhizophora apiculata</i> obtained the highest abundance. Results showed that the area is not diverse in terms of species composition and abundance, as shown by several indices of diversity.</p><p>This research article was published by the <a href="https://innspub.net/journal-of-biodiversity-and-environmental-sciences/">Journal of Biodiversity and Environmental Sciences | JBES</a></p>

AND A NEFY-BASED INSECTICIDE, MARGOSAN-0 ON AMYLASE, NONSPECIFIC ESTERASE, AND ACETYLCHOLINESTERASE ACTIVITY IN RTCE WEEVIL, Sitophilus oryzae L. Senior Adviser: Dr. Adelina A. Barrion Junior Adviser: Cesar G. Demayo The effect of neem oil, sweetflag oil and Margosan-O on mortality effects and the amylase, o( and 6-esterase and acetylcholinesterase activity in 5. oryzae was studied. The test on toxicity revealed that Margosan-O was most effective compared to sweetflag oil and neem oil. Amylase, of and g-esterase activities, as revealed by spectrophotometry, exhibited a general trend of decreasing enzyme activity in response to increased oil concentration. On the other hand, acetylcholinesterase activity increased with plant derivative concentration
Philippine traditional herbal remedies for hypertension
No full textCertain areas of the Philippines continue to rely on traditional non-pharmacological approaches, such as herbal medicine, for hypertension treatment, a significant public health problem globally. Therefore, a systematic review of plants used in the Philippines to treat hypertension, based on the PRISMA flow diagram, was carried out. Relevant ethnobotanical studies were retrieved from databases such as Google Scholar, ScienceDirect, and PubMed. Following the eligibility screening, 36 ethnobotanical studies were included. The majority of the studies included in this review came from Region XIII (CARAGA), Region VI (Western Visayas), and Region X (Northern Mindanao). The most prevalent plant family and species were Poaceae (12 species) and Cymbopogon citratus (DC.) Stapf. (16 citations), respectively. Leaves were the most common plant parts utilized while decoction was the most frequently mentioned mode of preparation. Oral administration was the most widely used form of administration. This review highlights medicinal plants with potential antihypertensive properties. It underscores the need to conduct a systematic review of their pharmacological properties to determine which have been scientifically validated and are most effective against hypertension

No full textHousehold level adaptive capacity of fishing communities in Western Mindanao, Philippines to the changing climate | JBES 2020
No full textClimate change has been affecting many coastal communities around the world. With the location of the Philippines in the tropics, the country is vulnerable to the impacts brought by this phenomenon affecting the safety, livelihood, and income distribution of the fishing communities in particular. Quantifying adaptive capacity to climate change is critical in reducing the vulnerability of these affected communities. This study was conducted to assess the adaptive capacity in the household level of the different social groups in the fishing communities of the Municipality of Sindangan, Zamboanga del Norte, Philippines. Using the interval-level scale generated from the eight indicators of adaptive capacity comprising human agency, capacity to change, occupational mobility, material assets, occupational multiplicity, social capital and infrastructure, and the Analytical Hierarchy Process (AHP), the data revealed differentiation between social groups. The result showed that fishers who are land tenants, members in fishing boats, large household sizes, fishers belonging in the age group of 29 to 36 years old, and fishers who finished High School are least prepared for the changes in climate. Findings of this study support previous findings of the adaptive capacity conducted around the world. These results highlight the most vulnerable sectors of society, which will help guide local policymakers to formulate environmental adaptation plans appropriate for the social groups in a fishing community

No full textIn the Philippines, kidney disease is acknowledged as a significant public health issue as it causes considerable suffering, negatively impacts health, and possibly death to people inflicted it, this is despite the available programs and efforts to combat these diseases. This study evaluated and analyzed six decades of data (1960-2019) from Philippine Health Statistics to provide precise and valid information regarding its mortality trend and to assess the country’s improvement in effectively dealing with these diseases. Factors such as gender, geographical location, and lifestyle were found to affect kidney disease chances. We also found out that there are age and gender disparities in the vulnerability of the people of the Philippines to kidney diseases, with elderly ages 70 and up and males recorded to be at greater risk of dying due to it. Differences in the regional outcome were also observed with Region XII having the highest mortality rate, and Region ARMM having the lowest. Urgent need to expand treatment advancements and programs for the population is needed to decrease the burden of kidney disease in the country in the following years
Epidemiology of typhoid fever in the Philippines during the last six decades from 1960-2019: a profile and its trend
No full textRegardless of the numerous reviews and publications on typhoid fever in the Philippines, it continues to be an issue regarding public health. Using data obtained from the Philippine Health Statistics (PHS), this study examined trends in typhoid fever mortality across an interval of six decades in the Philippines. The mortality and morbidity rates of typhoid fever were analyzed to discover trends of change for each year, age group, sex, and area. The Microsoft Excel software tool became used for all data analysis. The results show a decrease in typhoid fever fatality rates in the Philippines over the previous year. In terms of sex-specific deaths, males outnumbered females. The individuals aged 70 and older have the highest death rates when it comes to age-specific mortality rates. In the Philippines, Region I also has the highest mortality rate from typhoid fever. For instance, the Autonomous Region of Muslim Mindanao (ARMM) has the lowest mortality rate from typhoid fever. The highest average morbidity rate is in the Cordillera administrative region (CAR), while the lowest is in Region IVB. To eliminate typhoid fever in the next few years and to completely combat typhoid fever throughout the years, educational campaign awareness or intimate knowledge must be conducted locally and globally
