Mesiodistal and buccolingual crown dimensions of the right deciduous teeth of 133 white children were analyzed for information on sexual dimorphism and sex discrimination using discriminant analysis. Even though consistent differences were found for only 15 out of 20 paired measurements, five of them significant a t p = 0.05 or better, discriminant analysis showed the possibility of correctly s...

The sterile insect technique (SIT) is a biological control tactic that is used as a component of area-wide integrated pest management (AW-IPM) programs. The SIT can only be applied against disease-transmitting mosquitoes when only sterile male mosquitoes are released, and the blood-sucking and potentially disease-transmitting females are eliminated from the production line. For Anopheles arabie...

The Seychelles Giant Tortoise Conservation Project captive breeding programme for the Seychelles tortoises Dipsochelys arnoldi and D. hololissa is described. Successful hatching occurred in 2002 and the reasons for this success discussed. Important factors are enclosure design, social structure and the use of artificial incubation. Methods for sexing hatchlings are discussed. There may be great...

Abstract. Homchan S, Gupta YM. 2021. Short communication: Insect detection using a machine learning model. Nusantara Bioscience 13: 69-73. The key step in characterizing any organisms and their gender highly relies on correct identification of specimens. Here we aim to classify insect sex by supervised (ML) In the present preliminary study, used newly developed graphical user interface (GUI) ba...

Sex-role reversal, in which males care for offspring, can occur when mate competition is stronger between females than males. Secondary sex traits and mate attracting displays in sex-role-reversed species are usually more pronounced in females than in males. The red phalarope (Phalaropus fulicarius) is a textbook example of a sex-role-reversed species. It is generally agreed that males are resp...

The objective of this study was to develop a simplified, efficient, and accurate protocol for sexing goat embryos. Based on the amelogenin gene located on the conservation region of Xand Ychromosomes, a pair of primers was utilized and the system of PCR was established to amplify a 262 bp fragment from the Xchromosome in female goats, and a 262 bp fragment from Xchromosome and 202 bp fragment f...
