Antarctic krill (krill) are important within Southern Ocean ecosystems and support an expanding fishery. Toward understanding krill's response to environmental change, it is necessary identify regions that high larval production (spawning habitat). We develop a mechanistic model combining thermal food requirements for egg production, with predation pressure post-spawning, predict of high-qualit...

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 ...

The value of the dung of game animals as a larval habitat for Culicoides species was briefly investigated in 1973/74 in the Kruger National Park, Transvaal, Republic of South Africa. A total of 4 species in the subgenus Avaritia was reared, 3 from elephant dung, 2 from zebra dung and 1 from the dung of buffalo. These early studies have recently led to more intensive rearing and a better underst...

Deforestation impact studies have generally focused on tropical rainforests or temperate coniferous woodlands. However, extensive clear-cutting is currently occurring in a wide-ranging, but far less recognized habitat: the world's mangrove forests. These coastal forests thrive in areas of low wave action and high sediment availability, where mangrove trees develop dense and productive ecosystem...

Water from a mosquito larval habitat in Florida was collected periodically for one year. After removing debris and macroscopic organisms, the small particles were concentrated by continuous flow centrifugation and examined microscopically. Anopheles quadrimaculatus, Culex salinarius and Heliothis zea larvae were exposed to the concentrates. The microsporidia isolated were Nosema, Pleistophora, ...
