Nine genera and twenty-two species of heptageniid mayflies from Thailand are defined in this present work as well as one suggested further subgenus, Compsoneuria (Siamoneuria) kovaci (species "incertae sedis") including some particular characters. Taxonomic remarks, diagnoses, line drawings of key characters, distribution, habitat and biological data, and a larval key to the genera and species ...

In order to analyze variation and find an efficient selection approach, we used crossing results between two wheat cultivars, Azar2 and 87-Zhong291. F3 plants (374 lines) and four check cultivars planted in the form of augmented experiment. For germination, seeds were irrigated once. After using multiple statistics methods such as cluster analysis, 79 different lines were selected and used for ...

Understanding and solving biomedical problems requires insight into the complex interactions between the components of biomedical systems by domain and non-domain experts. This is challenging because of the enormous amount of data and knowledge in this domain. Therefore, non-traditional educational tools have been developed such as a biological storytelling system, animations of biomedical proc...

Twelve hybrids along with their seven parents were subjected to study the genetic variability indicated that genetic material in the present investigation possessed variability which provides sufficient basis for selection by breeder. High estimates of PCV and GCV were obtained for biological yield per plant and seed yield per plant indicated a good deal of variability in those characters signi...

748 Since Charles Darwin published The Origin of Species in 1859, his theory of evolution has been a central axiom for the biological sciences. Scientists have devoted considerable effort to unravelling the evolutionary mechanisms of biological, and other, systems. Their work—in particular the discovery of DNA as the carrier of hereditary information—has led to the now nearly universally accept...

Brathinus satoi Kishimoto & Shimada, 2003 is recorded from Longwangshan Nature Reserve, Zhejiang, China. Some diagnostic characters of the species are discussed based on more specimens, and some biological notes are made on the species.

A new species of cicada, Cicadatra ziaraticasp. n., is described from Pakistan. Male genitalia, timbal and opercula are described and illustrated as important diagnostic characters. Biological notes are also provided. A key to the known Cicadatra of Pakistan is provided.
