A Management Plan for the Black-Tailed Prairie Dog (Cynomys ludovicianus)

Thu, 04/30/2015 - 22:07
Abstract: Since the turn of the century black-tailed prairie dog (Cynomys ludovicianus) populations have declined as much as 98% throughout North America (Miller et al. 1994). It was once thought that prairie dogs occupied between 80-104 million acres historically, but with the expansion of ranching and agriculture into the prairie dogs native habitat, that number has been reduced to 2.4 million acres in recent years. Black-tailed prairie dogs play a vital role in the prairie and grasslands ecosystems. There are a number of different species of animals that depend on prairie dogs and their activities. It has been thought that over 170 species rely on the prairie dogs for their burrows, for food, and the habitat they create. Most states currently within the range of the black-tailed prairie dog classify the species as a pest or varmint, and no state has adequate regulatory mechanisms in place to assure conservation of this species within its borders. This management plan will propose strategies to adequately regulate the conservation of the black-tailed prairie dog, eventually leading to the partial restoration of the prairie ecosystem.

Optimal Clutch Size of American Kestrels (Falco sparverius) in Northern New York

Mon, 04/28/2014 - 12:08
Abstract: American kestrels readily use nest boxes, which makes them perfect candidates for studies on nesting activity and success. Nesting success is important to understand so that managers can effectively assess the productivity of a breeding population of kestrels. The goal of this study was to determine optimum clutch size for American Kestrels in Northern New York. The hypothesis was that optimum clutch size consisted of four eggs per clutch. The objective was to determine what clutch size is most effective at hatching young. The study was conducted during the months of June 2013 through August 2013 on 150 nest boxes that were established in 2002. The contents of each elevated nest box were observed using a video baby monitor attached to an extendible pole to minimize disturbance. Clutch size data and number of chicks hatched was compiled and analyzed using a Kruskal-Wallis test. This test was used because it allowed data to be separated into different clutch sizes, and determined the significance between the number of eggs in each clutch and the number of chicks hatched. Clutch sizes varied from 1-5 eggs, with occurrences of one and four eggs being most common. The majority of nesting attempts with one egg failed, resulting in a low probability of chicks hatching from one egg clutches. A clutch size of four eggs has the highest probability of successfully hatching chicks and the highest mean number of chicks hatched compared to the other clutch sizes.
