15 صفحه اولDivergent egg physiologies in two closely related grasshopper species: Taeniopoda eques versus Romalea microptera (Orthoptera: Romaleidae).
We compared egg survivorship and egg development time at different soil moistures for two closely related grasshopper species from divergent habitats: marsh-inhabiting Romalea microptera (Beauvois) versus desert-inhabiting Taeniopoda eques (Burmeister). These two species can interbreed and produce viable offspring. In nature, both species have a similar 8-9 mo subterranean egg stage, but their ...
متن کاملKARYOTYPIC STUDY OF TRIFOLIUM SPECIES AND CULTIVARS IN IRAN
Trifolium species and cultivars are considered important forage crops iran , growing throughout the country. The present article considered the karyotypic details of Trvulim taxa using multivariate statistical analysis. Taxa studied included: Trifolim restylinatum (six populations: Shazand, Soriyan, Kordestan, Harati, Enaj and Lordegan), T. repense, T, fragverm, T. prateme and T, alexandrin...
متن کاملGrasshopper (Orthoptera: Tettigoniidae) Species Composition and Size Across Latitude in Atlantic Coast Salt Marshes
Although grasshoppers are common salt marsh herbivores, we know little about geographic variation in their species composition. We documented latitudinal variation in species composition of the tettigoniid grasshopper fauna of Atlantic Coast salt marshes. Tettigoniids (N=740 adults) were collected from the Spartina alterniflora zone of 31 salt marsh sites across a latitudinal range of 13.19° (F...
متن کاملThe Spermatid Nucleus in Two Species of Grasshopper
The nuclear changes accompanying spermatid elongation have been studied in two species of grasshopper, Dissosteira carolina and Melanoplus femur-rubrum. Testes were fixed in 1 per cent buffered OsO(4), imbedded in butyl methacrylate, and examined as thin sections in the electron microscope. In both species nuclear changes during spermatid development involve (1) an early period, during which th...
