Chaoborus Astictopus

	Chaoborus Astictopus ''Chaoborus astictopus'', the Clear Lake gnat, is a species of phantom midges in the family Chaoboridae. The older larvae are commonly found in the profundal zone of lakes during the day and in the open waters at night, suggesting that they are negatively phototactic. The larvae can be vulnerable to the pathogen '' Thelohania corethrae'' during the winter season. They are also susceptible to the fungal pathogen ''Tolypocladium cylindrosporum ''Tolypocladium'' is a genus of fungi within the family Ophiocordycipitaceae. It includes species that are parasites of other fungi, insect pathogens, rotifer pathogens and soil inhabiting species with uncertain ecological roles. ''Tolypocladium' ....''

picture info	Chaoboridae Chaoboridae, commonly known as phantom midges or glassworms, is a family of fairly common midges with a cosmopolitan distribution. They are closely related to the Corethrellidae and Chironomidae; the adults are differentiated through peculiarities in wing venation. If they eat at all, the adults feed on nectar. The larvae are aquatic and unique in their feeding method: the antennae of phantom midge larvae are modified into grasping organs slightly resembling the raptorial arms of a mantis, with which they capture prey. They feed largely on small insects such as mosquito larvae and crustaceans such as ''Daphnia''. The antennae impale or crush the prey, and then bring it to the larval mouth, or stylet. The larvae swim and sometimes form large swarms in their lacustrine habitats. Description The larvae are nearly transparent, sometimes with a slightly yellow cast; their most opaque features are two air bags, one in the thorax, one in the abdomen about in the second last segment ...

	Profundal Zone The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration. This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly. The temperature difference may be large enough to hamper mixing with the littoral zone in some seasons which causes a decrease in oxygen concentrations. The profundal is often defined, as the deepest, vegetation-free, and muddy zone of the lacustrine benthal. The profundal zone is often part of the aphotic zone. Sediment in the profundal zone primarily comprises silt and mud. Organisms The lack of light and oxygen in the profundal zone determines the type of biological community that can live in this region, which is distinctly different from the community in the overlying waters. The profundal macrofauna is therefore characterized by physiological and behavioural adaptations to low oxygen concentration. While benth ...

	Tolypocladium Cylindrosporum ''Tolypocladium'' is a genus of fungi within the family Ophiocordycipitaceae. It includes species that are parasites of other fungi, insect pathogens, rotifer pathogens and soil inhabiting species with uncertain ecological roles. ''Tolypocladium'' was originally circumscribed as a genus containing anamorphic fungi. It was later determined that some ''Cordyceps''-like teleomorphic fungi were the teleomorphs of ''Tolypocladium'' species. These species were considered to belong in the genus ''Cordyceps'' until molecular phylogenetics studies found these species to be more closely related to ''Ophiocordyceps'' and were considered to belong in that genus before they were transferred to the new genus ''Elaphocordyceps'' by Sung and colleagues in 2007. However, under the ICN's 2011 " one fungus, one name" principle, fungi can not have different names for their anamorphic and teleomorphic stages if they are found to be the same taxon. Quandt and colleagues formally synonymized ''Tolypocl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
