Shapes of the Abdomen Between Sexes in Two Geographically Isolated Populations of Rana Ranina Using Landmark-Based Geometric Morphometrics and Multivariate Statistics

Dulce Amor Matondo, Cesar G. Demayo

This study was conducted to describe and compare the shapes of the abdomen between sexes in two geographically isolated populations of Rana ranina using landmark-based geometric morphometrics and multivariate statistics. The results showed that asymmetry was common among the sampled crabs; however, PCA-implied deformations revealed higher fluctuating asymmetry levels among female crabs collected from Siargao compared to those from Sacol. Although further studies are still warranted, the results could spell possible differences in the crab’s response to different environmental realities between Siargao and Sacol. A glaring result also from this research was the apparent preponderance of asymmetrical structures in nature and the rarity of the symmetry.

Entomology and Applied Science Letters is an international peer reviewed publication which publishes scientific research & review articles related to insects that contain information of interest to a wider audience, e.g. papers bearing on the theoretical, genetic, agricultural, medical and biodiversity issues. Emphasis is also placed on the selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance. Papers on non-insect groups are no longer accepted. In addition to full-length research articles and reviews, the journal publishes interpretive articles in a Forum section, Short Communications, and Letters to the Editor. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance.

Call for Papers
Entomology and Applied Science Letters supports the submission of entomological papers that contain information of interest to a wider reader groups e. g. papers bearing on taxonomy, phylogeny, biodiversity, ecology, systematic, agriculture, morphology. The selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance is also important. Distinguished entomologists drawn from different parts of the world serve as honorary members of the Editorial Board. The journal encompasses all the varied aspects of entomological research. This has become the need felt in scientific research due to the emphasis on intra-, inter-, and multi-disciplinary approach.
