Studies on the impacts of grazing carbon, nitrogen, and phosphorus stoichiometry storage are crucial for better understanding nutrient cycles grasslands ecosystems. Using a controlled experimental platform in meadow steppe ecosystem, effects different stocking rates (0.00, 0.23, 0.34, 0.46, 0.69, 0.92 AU ha?1) contents plant functional groups were explored. The major results were: (1) carbon co...

Early attempts at the biological control of the pyralid borer Eldana saccharina Walker were discussed in a paper presented at the Congress of the South African Sugar Technologists' Association in 1979. Since then further introductions of both egg and larval parasitoids have been made and include: Trichogrammatoidea eldanae Vigianni, Trichogramma sp and Telenomus applanatus Bin & Johnson (from W...

Eight cyperaceous Puccinia and Uromyces, viz. P. cariciola, P. conclusa, P. cyperi, P. eriophori, P. scirpi and Uromyces lineolatus subsp. lineolalus are reported as new to Iran. The uredinial stage of P. dioicae is reported as a new stage for this rust in Iran. Hosts new to P. eriophori are also given. Included is a key to the cyperaceous rust species in Iran.

<i>Eleocharis</i> R. Br. (Cyperaceae) is characterized by unbranched culms, one terminal spikelet, bisexual flowers, and bristly perianths, occurring mainly in circumboreal marshes wetlands. There are about 250 species worldwide, 15 taxa Korea have been recognized. Chromosomes Cyperaceae known to be holocentric, missing constricted centromeres during cell division. For the first tim...
