Contemporary Land-Use Change Structures Carnivore Communities in Remaining Tallgrass Prairie
Contemporary land-use change structures carnivore communities in remaining tallgrass prairie by Kyle Ross Wait B.S., Kansas State University, 2014 A THESIS submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Horticulture and Natural Resources College of Agriculture KANSAS STATE UNIVERSITY Manhattan, Kansas 2017 Approved by: Major Professor Dr. Adam A. Ahlers Copyright © Kyle Ross Wait 2017. Abstract The Flint Hills ecoregion in Kansas, USA, represents the largest remaining tract of native tallgrass prairie in North America. Anthropogenic landscape change (e.g., urbanization, agricultural production) is affecting native biodiversity in this threatened ecosystem. Our understanding of how landscape change affects spatial distributions of carnivores (i.e., species included in the Order ‘Carnivora’) in this ecosystem is limited. I investigated the influence of landscape structure and composition on site occupancy dynamics of 3 native carnivores (coyote [Canis latrans]; bobcat [Lynx rufus]; and striped skunk [Mephitis mephitis]) and 1 nonnative carnivore (domestic cat, [Felis catus]) across an urbanization gradient in the Flint Hills during 2016-2017. I also examined how the relative influence of various landscape factors affected native carnivore species richness and diversity. I positioned 74 camera traps across 8 urban-rural transects in the 2 largest cities in the Flint Hills (Manhattan, pop. > 55,000; Junction City, pop. > 31,000) to assess presence/absence of carnivores. Cameras were activated for 28 days in each of 3 seasons (Summer 2016, Fall 2016, Winter 2017) and I used multisession occupancy models and an information-theoretic approach to assess the importance of various landscape factors on carnivore site occupancy dynamics. -

222 Author’s name Bobcat Diet on an Area Managed for Northern Bobwhite Ivy A. Godbois, Joseph W. Jones Ecological Research Center, Newton, GA 39870 L. Mike Conner, Joseph W. Jones Ecological Research Center, Newton, GA 39870 Robert J. Warren, Warnell School of Forest Resources, University of Georgia, Athens, GA 30602 Abstract: We quantified bobcat (Lynx rufus) diet on a longleaf pine (Pinus palustris) dominated area managed for northern bobwhite (Colinus virginianus), hereafter quail. We sorted prey items to species when possible, but for analysis we categorized them into 1 of 5 classes: rodent, bird, deer, rabbit, and other species. Bobcat diet did not dif- fer seasonally (X2 = 17.82, P = 0.1213). Most scats (91%) contained rodent, 14% con- tained bird, 9% contained deer (Odocoileus virginianus), 6% contained rabbit (Sylvila- gus sp.), and 12% contained other. Quail remains were detected in only 2 of 135 bobcat scats examined. Because of low occurrence of quail (approximately 1.4%) in bobcat scats we suggest that bobcats are not a serious predator of quail. Key Words: bobcat, diet, Georgia, Lynx rufus Proc. Annu. Conf. Southeast. Assoc. Fish and Wildl. Agencies 57:222–227 Bobcats are opportunistic in their feeding habits, and their diet often reflects prey availability (Latham 1951). In the Southeast, bobcats prey most heavily on small mammals such as rabbits and cotton rats (Davis 1955, Beasom and Moore 1977, Miller and Speake 1978, Maehr and Brady 1986, Baker et al. 2001). In some regions, bobcats also consume deer. Deer consumption is often highest during fall- winter when there is the possibility for hunter-wounded deer to be consumed and during spring-summer when fawns are available as prey (Buttrey 1979, Story et al. -

Eastern Kentucky University Optimization of Camera Trapping Methods for Surveying Mesopredators in the Appalachian Foothills Honors Thesis Submitted in Partial Fulfillment of the Requirements of HON 420 Spring 2018 By Courtney R. Hayes Mentor Dr. Luke E. Dodd Department of Biological Sciences ii ABSTRACT Optimization of camera trapping methods for surveying mesopredators in the Appalachian foothills Courtney R. Hayes Dr. Luke E. Dodd, Department of Biological Sciences The global decline of apex predators has allowed mesopredator populations to increase, a phenomenon described by the mesopredator release hypothesis (MRH). Some mesopredator species, however, are of conservation concern, such as the eastern spotted skunk (Spilogale putorius). To assess camera deployment strategies and survey for the presence of eastern spotted skunks in the Appalachian Foothills, I conducted baited camera trap surveys in Kentucky, a state for which systematic methodological data is lacking. I surveyed 64 sites across 10 counties over more than 1,200 trap days from October 2017 to April 2018. -

First Documentation of Scent-Marking Behaviors in Striped Skunks (Mephitis Mephitis)
Mammal Research (2021) 66:399–404 https://doi.org/10.1007/s13364-021-00565-8 ORIGINAL PAPER First documentation of scent-marking behaviors in striped skunks (Mephitis mephitis) Kathrina Jackson1 & Christopher C. Wilmers 2 & Heiko U. Wittmer 3 & Maximilian L. Allen4 Received: 9 October 2020 /Accepted: 16 March 2021 / Published online: 11 April 2021 # Mammal Research Institute, Polish Academy of Sciences, Bialowieza, Poland 2021 Abstract Communication behaviors play a critical role in both an individual’s fitness as well as the viability of populations. Solitary animals use chemical communication (i.e., scent marking) to locate mates and defend their territory to increase their own fitness. Previous research has suggested that striped skunks (Mephitis mephitis) do not perform scent-marking behaviors, despite being best known for using odor as chemical defense. We used video camera traps to document behaviors exhibited by striped skunks at a remote site in coastal California between January 2012 and April 2015. Our camera traps captured a total of 71 visits by striped skunks, the majority of which (73%) included a striped skunk exhibiting scent-marking behaviors. Overall, we documented 8 different scent-marking behaviors. The most frequent behaviors we documented were cheek rubbing (45.1%), investigating (40.8%), and claw marking (35.2%). The behaviors exhibited for the longest durations on average were grooming (x =34.4s) and investigating (x = 21.2 s). Although previous research suggested that striped skunks do not scent mark, we documented that at least some populations do and our findings suggest that certain sites are used for communication via scent marking. -
STRIPED SKUNK Mephitis Mephitis
WILDLIFE IN CONNECTICUT INFORMATIONAL SERIES EASTERN STRIPED SKUNK Mephitis mephitis Habitat: Fields, fencerows, wooded ravines and rocky Diet: Insects (especially grubs), small mammals, outcrops. May also be found under buildings, in culverts earthworms, snails, grains, nuts, fruits, reptiles, vegeta- and near garbage dumps. tion, amphibians, birds, eggs, carrion and garbage. Weight: 6 to 14 pounds. Length: 21 to 26 inches. Males are somewhat larger than females. Identification: The eastern striped skunk’s body is born between late April and early June. At three weeks covered with fluffy black fur. It has a narrow white stripe of age, young skunks open their eyes and begin up the middle of the forehead and a broad white area crawling. At seven weeks, they begin to venture out on the top of the head and neck, which usually divides with the female and are able to spray musk; they into two stripes continuing along the back. The long, usually disperse during the fall of their first year. Adult bushy tail is a mixture of white and black hairs. Some males are generally solitary except during the mating skunks have more white than black hairs. Skunks have season. a small head, small eyes and a pointed snout. Their History in Connecticut: The eastern striped skunk is short legs and flat-footed gait makes them appear to adaptable to a wide range of habitats but prefers areas waddle when they walk. Sharp teeth and long claws of open fields with low, brushy vegetation. Early enable them to dig in soil or sod and pull apart rotten farming in Connecticut probably increased the suitability logs in search of food. -

The 2008 IUCN Red Listings of the World's Small Carnivores
The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome.

Understanding species 20 boundaries within this group is critical for effective conservation given that regional populations 21 or subspecies (e.g., S. p. interrupta) have experienced significant population declines. Further, 22 there may be currently unrecognized diversity within this genus as some taxa (e.g., S. 23 angustifrons) and geographic regions (e.g., Central America) never have been assessed using 24 DNA sequence data. We analyzed species limits and diversification patterns in spotted skunks 25 using multilocus nuclear (ultraconserved elements) and mitochondrial (whole mitogenomes and 26 single gene analysis) data sets from broad geographic sampling representing all currently 27 recognized species and subspecies.
