Status of the common muskrat (Ondatra zibethicus) in the southern High Plains and western Rolling Plains has remained uncertain due to a scarcity of records. I examined diversity of riparian habitats, frequency of occurrence of habitats, availability of habitats, and use of habitats by muskrats within an irrigation drainage system in southwestern Oklahoma during prolonged drought. Six major hab...

In 1980 the State of Connecticut began a tidal marsh restoration program targeting systems degraded by tidal restrictions and impoundments. Such marshes become dominated by common reed grass ( Phragmites australis ) and cattail ( Typha angustifolia and T. latifolia ), with little ecological connection to Long Island Sound. The management and scientific hypothesis was that returning tidal action...

Nonbreeding shorebirds often alternate social structure between anonymous flocks and territorial behavior in response to different environmental factors. To evaluate specific drivers for one species, we studied the spacing behavior of wintering Western Sandpipers (Calidris mauri) at Bahı́a Santa Maŕıa, northwestern Mexico, using behavioral observations. The density, population structure, and ter...

A microcosm study was conducted in Okeechobee, County, Florida, to evaluate the P removal potential of several aquatic macrophytes and "unconventional" terrestrial crops cultured on dairy lagoon wastewaters. Existing conventional spray field crops in this region that are irrigated with dairy wastewaters are estimated to remove 23 mgP/m-'-day. Effects of season and hydraulic retention time (HRT)...

the usage of ceramic composites in order to improve the workability and properties of clay already has past a long history behind. in spite of the fact that clay by its own is a flexible and appropriate material for sculpting and ceramic making, it also carries some problems, flaws and imperfections (such as cracking, heaviness and etc.) which make it somehow troublesome to work with. from the ...

—To assess the relationship between marsh area and relative abundance of tidal marsh bird species, we surveyed birds on 86 circular plots in 40 salt and brackish tidal marshes in Connecticut. We measured marsh area in two ways: the amount of contiguous marsh vegetation not interrupted by broad barriers (.500 m of open water or .50 m of upland habitat) and by narrow barriers (.30 m of open water...
