Adamaeus Norton, 1978 and Paradamaeus Bulanova-Zachvatkina, 1957, two subgenera of genus Damaeus C. L. Koch, 1835, are reviewed on the basis of the redescription of their type species. Subgenus Eudamaeus Pérez-Iñigo, 1987 and genus Tectodamaeus Aoki, 1984 are reviewed and their relation to Damaeus is discussed. Damaeus firmus Kunst, 1957 is redescribed and placed into the nominate subgenus. Dam...

Landscape genetics holds promise for the forecasting of spatial patterns of genetic diversity based on key environmental features. Yet, the degree to which inferences based on single species can be extended to whole communities is not fully understood. We used a pristine and spatially structured community of three landlocked salmonids (Salvelinus fontinalis, Salmo salar, and Salvelinus alpinus)...

In the South, most nursery managers have relied on methyl bromide for weed control in hardwood seedbeds. When methyl bromide is no longer available, handweeding times will likely increase unless management regimes adapt to the change. Some nursery managers will increase use of both sanitation practices and herbicides. Although several herbicides are registered for use on hardwoods, some can inj...

Morphological divergence was evident among three sympatric morphs of Arctic charr (Salvelinus alpinus (L.)) that are ecologically diverged along the shallow-, deep-water resource axis in a subarctic postglacial lake (Norway). The two deep-water (profundal) spawning morphs, a benthivore (PB-morph) and a piscivore (PP-morph), have evolved under identical abiotic conditions with constant low light...

The flooding dose technique of Garlick et al. (1980) has become the main method for measuring tissue and whole-animal rates of protein synthesis in ectotherms. However, single tissue samples are used to determine rates of protein synthesis and no studies have examined the pattern of flooding in large tissues such as the white muscle in fishes, which can comprise up to 55% of the wet body mass o...
