Management Of The Houtman Abrolhos System, Abrolhos Islands Management Advisory Council, Fisheries Department Of Western Australia
Management Of The Houtman Abrolhos System, Abrolhos Islands Management Advisory Council, Fisheries Department Of Western Australia
Fisheries management papers
In November 1995 Cabinet resolved that the Minister for Fisheries would establish the Abrolhos Islands Management Advisory Committee (AIMAC) pursuant to Section 42 of the Fish Resources Management Act 1994. The role of AIMAC is to advise the Minister for Fisheries about the management of the Abrolhos Islands and the adjoining State Territorial Waters, as detailed in Section 2.2.3.1 of this report. The AIMAC has overseen the preparation of this report on behalf of the Minister for Fisheries. This draft report contains a brief description of the Abrolhos System and its special values. It also states goals and objectives for …

Ecological Relationships Between The Marsh Rice Rat (Oryzomys Palustris) And The Meadow Vole (Microtus Pennsylvanicus) In Two Virginia Tidal Marshes, Christopher P. Bloch
Ecological Relationships Between The Marsh Rice Rat (Oryzomys Palustris) And The Meadow Vole (Microtus Pennsylvanicus) In Two Virginia Tidal Marshes, Christopher P. Bloch
Biological Sciences Theses & Dissertations
Small mammals were trapped for 23 months on two live trap grids in tidal marshes in Northampton County, on the Eastern Shore of Virginia, to examine ecological relationships between the marsh rice rat (Oryzomys palustris) and the meadow vole (Microtus pennsylvanicus). Population density, survival rates, capture probability, recruitment, residence time, and home range size were calculated for each species. Patterns of reproductive activity and fluctuations in mean weight were also observed.
There were considerable differences in population dynamics between the two sites. At Grid 2, where vegetative cover was more abundant, population densities of rice rats and meadow voles …
Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier
Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier
Proceedings of the North American Crane Workshop
Aerial videography in 1988 and 1994 of the same selected segments of the Big Bend reach of the Platte River in central Nebraska was compared. During this 6-year period, channel area declined 4 to 41 % (median 26%). In river segments where the channel had already narrowed significantly and at sites where channel habitat is actively managed declines were less (17-18%). These substantial changes occurred during a time that included a relatively low flow period (1990-92). Flows during the summer gertttination and establishment period (mid-May through August) for cottonwood (Populus deltoides) and willow (Salix spp.), the …
Diet And Growth Of Larval And Juvenile Grass Pickerel, Esox Americanus Vermiculatus, And Central Mudminnow, Umbra Limi, In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Erica Midkiff
Theses, Dissertations and Capstones
The grass pickerel, Esox americanus vermiculatus, is listed as Undetermined on the Vertebrate Species List of Concern in West Virginia. The central mudminnow, Umbra limi, is a disjunct population in Green Bottom Swamp. The lentic, vegetated areas that are required for spawning for the grass pickerel and the central mudminnow have been reduced by residential, agricultural, and industrial developments. Green Bottom Swamp, a naturally occurring wetland of 58 ha, and a nearby mitigated wetland of 29 ha, provides spawning habitat for the grass pickerel and the mudminnow. Fishes were collected in beds of Potamogetan crispus and Ceratophyllum demursum …
