Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Since 1991, 19 specific black-footed ferret reintroduction projects have been conducted across 8 States, Canada, and Mexico. All five of the first ferret reintroductions (from 1991 to 1996) continue to be occupied by ferrets. The photographs of October 31 and November 1 are the first unequivocal documentation of black-footed ferrets on the Standing Rock Indian Reservation. Ferrets observed on Standing Rock may be dispersals from the nearby Cheyenne River Sioux Indian Reservation to the south. The nearest re-introduction site for ferrets is approximately 20 miles away, in Whitehorse, South Dakota, and the observation of ferrets on Standing Rock could document ...


Different Open-Canopy Vegetation Types Affect Matrix Permeability For A Dispersing Forest Amphibian, Brittany Cline, Malcolm L. Hunter Jr. Apr 2014

Different Open-Canopy Vegetation Types Affect Matrix Permeability For A Dispersing Forest Amphibian, Brittany Cline, Malcolm L. Hunter Jr.

Population viability often depends on conserving functional connectivity in fragmented landscapes. For pool-breeding amphibians, population connectivity is largely maintained through juvenile dispersal, often through various vegetation types that may differ as filters or conduits to movement. We quantified the relative permeability of different types of open-canopy vegetation to juvenile wood frogs Lithobates sylvaticus to determine whether this influences functional connectivity during dispersal. We conducted experimental releases of juveniles (n = 561) in ten runways representing five treatments: hayfield, moderate-cover lawn (45–85% cover), open lawn (0% cover), row crop (forage-corn) and recent clear-cut. Runways consisted of 35 × 2·5 m enclosures ...

ECU Publications Post 2013

A movement ecology framework is applied to enhance our understanding of the causes, mechanisms and consequences of movement in seagrasses: marine, clonal, flowering plants. Four life-history stages of seagrasses can move: pollen, sexual propagules, vegetative fragments and the spread of individuals through clonal growth. Movement occurs on the water surface, in the water column, on or in the sediment, via animal vectors and through spreading clones. A capacity for long-distance dispersal and demographic connectivity over multiple timeframes is the novel feature of the movement ecology of seagrasses with significant evolutionary and ecological consequences. The space–time movement footprint of different ...
