The horse and deer flies (Diptera: Tabanidae) of Rhode Island The horse and deer flies (Diptera: Tabanidae) of Rhode Island
The Tabanidae of Rhode Island were surveyed using Rhode Island canopy traps placed at 20 locations in the state during the summers of 1999 and 2000. In total, 5,120 flies were collected, which included 55 species in the genera Chrysops, Hybomitra, Tabanus, Merycomyia, and Stonemyia. Distributional and ecological information is provided for each species in Rhode Island.

full text: Frogs and toads are perhaps the most approachable and available of all our wildlife. In many, if not most places, they are abundant. In wetter parts of the East, almost anyone outside on a warm rainy night in spring will hear their dream-like calls, bellows, trills and snores. Even in the deserts of the Southwest, a nocturnal trip after a summer monsoon will yield toads moving

Microscopic analysis of feather and hair fragments associated with human mummified remains from Kagamil Island, Alaska Microscopic analysis of feather and hair fragments associated with human mummified remains from Kagamil Island, Alaska
Human mummified remains of 34 different infant and adult individuals from Kagamil Island, Alaska, are accessioned in the Department of Anthropology, National Museum of Natural History, Smithsonian Institution. Kagamil Island is one of the small islands in the Island of Four Mountains group of the Aleutian Islands, Alaska and is well known for the mummy caves located on the southwest...

The midwinter survey of black ducks, locally and regionally The midwinter survey of black ducks, locally and regionally
The Midwinter Waterfowl Inventory (MWI) has been conducted consistently in Maryland since 1955 and in Virginia since 1957. Maryland currently focuses surveys in 30 segments along the Chesapeake Bay, Potomac River, and Atlantic Coast, whereas Virginia focuses on 22 segments centered over the eastern shore of Chesapeake Bay and along the tidewater areas of Back Bay and western shore...

Sources, fate, and effects of PAHs in shallow water environments: a review with special reference to small watercraft Sources, fate, and effects of PAHs in shallow water environments: a review with special reference to small watercraft
Polycyclic aromatic hydrocarbons (PAHs) are aromatic hydrocarbons with two to seven fused carbon (benzene) rings that can have substituted groups attached. Shallow coastal, estuarine, lake, and river environments receive PAHs from treated wastewater, stormwater runoff, petroleum spills and natural seeps, recreational and commercial boats, natural fires, volcanoes, and atmospheric...

Supplemental planting of early successional tree species during bottomland hardwood afforestation Supplemental planting of early successional tree species during bottomland hardwood afforestation
Reforestation of former bottom land hardwood forests that have been cleared for agriculture (i.e., afforestation) has historically emphasized planting heavy-seeded oaks (Quercus spp.) and pecans (Carya spp.). These species are slow to develop vertical forest structure. However, vertical forest structure is key to colonization of afforested sites by forest birds. Although early...

Comment [on 'Are Proterozoic cap carbonates and isotopic excursions a record of gas hydrate destabilization following Earth’s coldest intervals?, Kennedy et al., Geology 29(5), 442-446] Comment [on 'Are Proterozoic cap carbonates and isotopic excursions a record of gas hydrate destabilization following Earth’s coldest intervals?, Kennedy et al., Geology 29(5), 442-446]
We welcome the evidence noted by Kennedy et al. (2001) for strong methane excursions associated with the cessation of glacial episodes. They identify the carbon in cap carbonates overlying glacial sediments as probably being of biogenic origin and as likely having had a biogenic methane source. These authors suggest that the methane was released from gas hydrate, which we agree is likely...
