Oviposition Behavior in Two Species of Dragonflies
A comparative study of oviposition behavior of the dragonflies, Anax junius and Tramea onusta, was undertaken for two successive years in Tinley Park, Illinois. It was found that females of both species use tandem position and oviposit in close association with males. In A. junius, however, the male is physically attached to (tandem with) the ovipositing female during the actual act of oviposit...

15 صفحه اولdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولMeiotic behavior of interspecific hybrids
The meiotic behavior of four interspecific promising hybrids was evaluated by conventional cytological methods. The female genitors were two artificially tetraploidized sexual accessions of B. ruziziensis (R41 and R44, 2n = 4 χ = 36), which were crossed to an agronomically superior natural tetraploid apomictic genotype of B. brizantha (B140 BRA003395). Three of them (HBGC313, HBGC 315, and HBGC...
متن کاملInterspecific evaluation of octopus escape behavior.
The well-known ability of octopuses to escape enclosures is a behavior that can be fatal and, therefore, is an animal welfare issue. This study obtained survey data from 38 participants-primarily scientists and public aquarists who work with octopuses-on 25 described species of octopus. The study demonstrates that the likeliness to escape is species specific (p =.001). The study gives husbandry...
