The Ozark pocket gopher (Geomys bursarius ozarkensis) has recently been described as a new subspecies of the plains pocket gopher (G. bursarius) inhabiting north-central Arkansas and is considered a "species of greatest conservation need" in Arkansas; therefore, research on spatial use and life-history characteristics were conducted via radio telemetry to elucidate home range and mortality. Home range size was associated negatively with adult female body mass, but was positively associated with juvenile body mass. Home range size showed no pattern with either adult or juvenile male mass. Home ranges were significantly larger for females in the winter/spring versus spring/summer probably due to food availability varying with season and the concurrence of the reproductive season in spring. The majority of pocket gopher mortality occurred in the winter months, during the period of increased movement. We documented two sources of mortality for pocket gophers: predation and flooding. © 2010, American Midland Naturalist. Source

Between May 2012 and July 2013, 4 eastern hognose snakes (Heterodon platirhinos) were collected from Arkansas (n = 2) and Oklahoma (n = 2), U.S.A., and examined for coccidians. Feces from a single H. platirhinos from Arkansas, U.S.A., were found to be contain oocysts of Caryospora lampropeltis Anderson, Duszynski, and Marquardt, 1968. Oocysts obtained from host feces were spheroidal to slightly subspheroidal with a rough, colorless, and bilayered wall, measure 23.5 × 22.8 μm, and with a length/width (L/W) ratio of 1.0; both micropyle and oocyst residuum were absent, but a prominent polar granule was present. Sporocysts were ovoidal, 16.8 × 12.8 μm, L/W of 1.3; a prominent Stieda and sub-Stieda body was present; a sporocyst residuum was present and composed of numerous spheroidal granules dispersed into small and large granules. Sporozoites lie lengthwise and parallel in a semispiral in the sporocyst; a spheroidal anterior refractile and a posterior refractile body are present; a single nucleus is located between the 2 refractile bodies. To our knowledge, this represents the first report of a caryosporan reported from H. platirhinos as well as the only known coccidian from this host. A summary of hosts of C. lampropeltis is provided. © 2015 The Helminthological Society of Washington. Source

Comparative Parasitology

Between November 2012 and July 2013, 34 banded sculpins (Cottus carolinae) were collected from 5 counties of northern Arkansas and examined for helminths. Five (19%) were infected with 1 or more helminths, including 2 (6%) with the trematode Crepidostomum cooperi, 3 (9%) with the trematode Plagioporus sp., 1 (3%) with the nematode Spiroxys sp., and 1 (3%) with the acanthocephalan Acanthocephalus tahlequahensis. One (3%) was concurrently infected with C. cooperi, Plagioporus sp., and Spiroxys sp. We document new host records for each of these helminths and 2 new distributional records for C. cooperi and A. tahlequahensis. © The Helminthological Society of Washington. Source

Between February 2013 and October 2013, eleven tri-colored bats, Perimyotis subflavus were collected from Marion, Polk, and Searcy counties, Arkansas, and their faeces examined for coccidian parasites. Two of eleven (18%) harboured an eimerian that we describe here as new. Oocysts of Eimeria mcdanieli sp. n. were ellipsoidal to elongate with a bi-layered wall and measured (length × width, L × W) 28.3 × 17.9 μm, with an L/W ratio of 1.6. A micropyle and oocyst residuum were absent but a single polar granule was present. Sporocysts were ovoidal, 12.6 × 8.3 μm, with an L/W ratio of 1.5. A pronounced, nipple-like Stieda body was present as well as a substieda body. A sporocyst residuum was present as dispersed bubble-like granules. This is the third coccidian described from tri-colored bats and the sixth species reported from Arkansas chiropterans. In addition, both infected bats harbored a concurrent infection of Eimeria heidti McAllister, Burt, Seville, and Robison, 2011. © 2014 Versita Warsaw. Source

We examined the reproductive status of Baird's pocket gophers (Geomys breviceps) in Union Parish, Louisiana, for 18 months in 2010 and 2011. We found that pocket gophers were potentially reproductively active throughout the year, although the number of reproductively active gophers peaked during late spring through autumn. Our results are similar to those of studies of Baird's pocket gopher in other states and of other pocket gophers in the genus Geomys. Source
