Reproductive Schedule Of The Silver Shiner (Notropis Photogenis) In The Flint River Of Alabama, Kelly Hodgskins, Stephanie Greenleaf, Jonathan Hillman, Bruce Stallsmith
Southeastern Fishes Council Proceedings
Many river-dwelling species of fish are dependent upon and stimulated by fluctuations in river flow for successful reproduction. This is especially true of pelagophils, a reproductive guild whose eggs and larvae require free drifting on river currents for several days. Notropis photogenis (Silver Shiner) is a rheophilic species with a broad distribution from Ontario to the southeastern United States including northern tributaries to the Tennessee River in Alabama. Little is known of its reproductive biology. The purpose of this study was to describe aspects of reproductive biology such as timing and pattern of ovarian development and oocyte maturation of N. …
Occupancy Rates And Detection Probabilities Of Red-Backed Salamanders On The Virginia Fall Line, Jay D. Mcghee
Occupancy Rates And Detection Probabilities Of Red-Backed Salamanders On The Virginia Fall Line, Jay D. Mcghee
Virginia Journal of Science
To meet the conservation needs of declining amphibian populations, there is a need to assess monitoring techniques in various habitat types and seasons. I assessed detection rates and proportion of area occupied via transect monitoring for red-backed salamanders at a site along the Virginia Fall Line in Doswell, Virginia. I established 24 transects in a 3.2-ha area in both riparian and upland habitats. Objects providing natural cover along these transects were sampled 3 times a week in fall and spring over a two-year period. Models of occupancy and detection were developed and compared using Akaike’s Information Criterion. Based on 113 …
Declining Frequency Of Road-Killed Rabbits In Central Georgia, Anna M. Bosch, Katelyn J. Benson, Alfred J. Mead
Declining Frequency Of Road-Killed Rabbits In Central Georgia, Anna M. Bosch, Katelyn J. Benson, Alfred J. Mead
Georgia Journal of Science
Cottontail rabbits (Sylvilagus floridanus, Sylvilagus aquaticus, Sylvilagus palustris) are a common component of the mammal fauna of the southeastern United States, yet their numbers have been in decline for at least the past 40 years. Urban sprawl, land use changes, forest maturation, and increased predation have contributed to the decline in Georgia. In the current study we explore the proposition that long-term changes in roadkill frequency track changes in wildlife populations as a whole. Using comparisons of historical data collected by Georgia Department of Natural Resources personnel and recent roadkill census data from Baldwin County, it appears that the overall …
