Ptomaphaminus granophilus n. sp. from Vietnam is described and illustrated. The special subterranean biotope of this species, deep interstices in a granitic blockfield, is emphasized.

subterranean termites are one of the most important pests of buildings, historic monuments and agricultural crops in some parts of iran. using entomopathogenic fungi as microbial insecticides is usually a part of biological control and insect pest management. the pathogenicity of entomopathogenic fungus, metarhizium anisopliae (metschnikoff) sorokin (demi 001) isolated from rhynchophorus ferrug...

This thesis identifies operational uncertainty as a significant problem affecting reliable robot performance in real environments. Operational uncertainty represents ambiguity in a robot’s self-perceived state during the execution of a task. This ambiguity is introduced into a robotic system through events such as unanticipated environmental disturbances, failing hardware and software built upo...

of fasting are experienced by numerous subterranean (i.e. hypogean) aquatic organisms, as many groundwater ecosystems are characterized yearly by severely limited food supplies due to lack of autotrophic production and sporadic allochthonous input (Poulson, 1964; Hüppop, 1985; Hervant et al., 1997). Even in highly productive hypogean biotopes, food resources may be extremely patchy (Malard and ...

Sources and sinks of methane (CH4 ) are critical for understanding global biogeochemical cycles and their role in climate change. A growing number of studies have reported that CH4 concentrations in cave ecosystems are depleted, leading to the notion that these subterranean environments may act as sinks for atmospheric CH4 . Recently, it was hypothesized that this CH4 depletion may be caused by...

microcerotermes diversus silvestri is the most economically destructive termite in structures in ahvaz (iran), and it consumes almost anything containing cellulose. this species lives in subterranean nests and gains access to buildings and vegetation by constructing underground galleries. because of their insecticidal activity, boron compounds may be beneficial for treating soil to create insec...

Broad-scale patterns of subterranean diversity are a fascinating but neglected part of biodiversity research. Carabid beetles adapted to belowground habitats form a particularly species-rich part of the subterranean fauna. We studied large-scale diversity patterns of these belowground carabids across the western Palaearctic and evaluated potential impacts of historical and contemporary environm...
