Geometric morphometric analysis in determining phenotypic variability of Bugwan,(Hypseleotris agilis, Herre) in Lake Mainit, Philippines

The environment and genetic composition highly attribute to the phenotypes of an organism. This study was carried out to assess the phenotypic variability in the body shapes of Hypseleotris agilis or locally known as Bugwan from Lake Mainit, Philippines using Geometric Morphometric Analysis. Sixty samples consisting of 30 males, and 30 females were randomly collected […]

Synthesis, analysis and biological studies of transition metal complexes of cefixime

Cephalosporin is extensively used broad-spectrum antibiotic, containing β-lactam ring. However, due to overuse of this drug many bacteriological pathogens are now resistant. The study aim to prepare new derivatives of above drug, which will enhance biological activity against pathogens. In current study, cefixime was reacted with essential trace elements to synthesize respective metal complexes. It […]

Intraspecific evaluation in the morphology of Glossogobius guiris using geometric morphometric analysis from lake Mainit, Agusan del Norte, Philippines

Morphological variations among organism have been baseline information to which species may vary from one and another. This study has been conducted to determine the intraspecific evaluation in the morphology of Glossogobius guiris using geometric morphometric analysis from Lake Mainit, Agusan del Norte, Phils. About 60 individuals (30 males and 30 females) were collected and […]

Morphological and molecular analysis of commercial Cordyceps militaris strains in Thailand

Cordyceps militaris, an entomopathogenic fungusi, has been extensively utilized for many years as a functional food and for medicinal activities in Thailand. The fungus has numerous strains which are commonly sold in herbal markets and not all have been identified. Seven commercial C. militaris strains (CM–s1, CM–s2, CM–s3, CM–s4, CM–s5, CM–s6 and CM–s7) were studied using […]

Describing intermediate host snails in Kapatagan, Lanao del Norte, Philippines: a phenetic analysis

Many species of freshwater snails served as intermediate hosts of highly infective fluke (trematode) larvae of the genus Schistosoma which cause Schistosomiasis however, the nature of populations remained ambiguous. This study shed light on the nature of populations of intermediate hosts snails from two barangays: Curvada and Tiacungan, Kapatagan, Lanao del Norte, Philippines. This study […]

Landmark-based geometric morphometric analysis of forewing sexual dimorphism in mycalesisita

This study presents the phenotypic variation in sexual dimorphism on wing shape of Mycalesisita. Butterfly wings hold highly diverse phenotypes as a result of interactions between adaptive processes, phylogenetic history and developmental constraints. The results of this study revealed that there is no considerable difference in wing morphology within sexes in both sites, though sexual […]

Determining developmental instability via fluctuating asymmetry in the shell shape of Venerupis philippinarum (Manila Clam)

This exploratory study look into the nature and variation of Manila Clams (Venerupis philippinarum), an edible species of saltwater clam native to Japan but has been cultivated, commercially harvested and considered as the second most important bivalve grown in aquaculture in the Philippines also worldwide. Fluctuating Asymmetry (FA) is apopular tool to estimate the quality, […]

Describing body shape variation of bugwan fish (Hypseleotris agilis) species using land mark-based geometric morphometric in Lake Mainit, Surigao del Norte, Philippines

The study primarily aimed to determine the body shape variation of Hypseleotris agilis using Fluctuating Asymmetry (FA) in relation to their existing population in Lake Mainit, Surigao del Norte, Philippines. The research used Procrustes ANOVA and Principal Component Analysis (PCA) by means of Symmetry and Asymmetry in Geometric Data (SAGE) software to analyze the data. […]

Skull shape variation in the Armored Sailfin catfish, Pterygoplichthys disjunctivus (Siluriformes: Loricariidae), described using geometric morphometrics

The two-dimensional shapes of the skulls of male and female Armored Sailfin Catfish, Pterygoplichthys disjunctivus, were reconstructed in this study using Thin-Plate Spline (TPS) grids. The rationale for doing this is to draw out hypotheses regarding the life history and population dynamics of the Armored Sailfin Fish, which is becoming a nuisance in some freshwater […]
