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 […]

Morphological characterization and diversity analysis of some selected aromatic rice genotypes in Bangladesh

The improvement of aromatic rice genotypes requires proper characterization of its existing germplasm. For this purpose, twenty four (nineteen aromatic and five non-aromatic fine) rice genotypes were evaluated for twenty qualitative and sixteen quantitative traits at morphological level to identify the suitable genotypes for future hybridization program at Bangabandhu Sheikh Mujibur Rahman Agricultural University. All […]

Population analysis via fluctuating asymmetry in the wings of Culex quinquefasciatus say from selected breeding sites in Iligan City, Philippines

Fluctuating asymmetry (FA) refers to the unequal bilateral sides of an organism. It occurs when an individual is unable to undergo identical development on both sides of a bilaterally symmetrical trait. It measures the sensitivity of development to a broad array of environmental and genetic stresses. In this study, FA was used to measure developmental […]
