Fishes Of The Pine Bluff Arsenal, Jefferson County, Arkansas, Henry W. Robison
Fishes Of The Pine Bluff Arsenal, Jefferson County, Arkansas, Henry W. Robison
Journal of the Arkansas Academy of Science
A survey of the fishes of the Pine Bluff Arsenal (PBA) located in Jefferson County, Arkansas was initiated in February 1999 and continued until October 1999 with several supplemental collections made in 2000. A total of 3,396 fishes was taken in 81 collections on the PBA and revealed 59 species distributed in 17 families and 36 genera. The most abundant fishes collected were Dorosoma petenense, Gambusia affinis, Labidesthes sicculus, Notemigonus crysoleucas, and Lepomis marginatus.
Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan
Small Fish Species Of Arkansas Reservoirs, Thomas M. Buchanan
Journal of the Arkansas Academy of Science
Sixty-six Arkansas reservoirs were sampled with rotenone from 1997 through 2004 to determine the distribution and species richness of small, nongame fish species in manmade lentic environments. Eighty-five small fish species distributed among 13 families were collected. Fish distribution and species richness varied by reservoir size, ecoregion, and reservoir type. Species richness was significantly correlated with reservoir size and the number of small species occurring in reservoir drainages. Some small species apparently maintained breeding populations in reservoirs, other species occurred in low numbers and may not have maintained breeding populations, and some species occurred sporadically, probably as stragglers from nearby …

Distribution Of Bats In Bottomland Hardwood Forests Of The Arkansas Delta Region, H. Bobby Fokidis, Stephen C. Brandebura, Thomas S. Risch
Journal of the Arkansas Academy of Science
Bat distribution data is incomplete for the delta region of Arkansas. We extensively surveyed 16 counties within the Mississippi alluvial plain that comprises the delta from late spring to early fall 2004 using mist nets. We obtained 44 new county records for 9 species: Myotis lucifigus, M. austroriparius, Pipistrellus subflavus, Eptesicus fuscus, Lasiurus seminolus, L. borealis, L. cinereus, Nycticeius humeralis, and Corynorhinus rafinesquii. We generated updated distribution maps for these species and eastward Arkansas range expansions were documented for L.seminolus. Possible sampling concerns and research directions are discussed in relation to the needs of bats inhabiting bottomland forests of the …
Seasonal Incidence Of Sperm Within The Spermathecae Of Ouachita Dusky Salamanders (Desmognathus Brimleyorum) In Arkansas, Stanley E. Trauth, Michelle N. Mary
Seasonal Incidence Of Sperm Within The Spermathecae Of Ouachita Dusky Salamanders (Desmognathus Brimleyorum) In Arkansas, Stanley E. Trauth, Michelle N. Mary
Journal of the Arkansas Academy of Science
We examined 91 adult female Ouachita dusky salamanders {Desmognathus brimleyorum) to determine the seasonal incidence of sperm within spermathecae. The spermatheca (sperm storage gland) along with supporting tissue was removed from the dorsal cloacal wall of each female and prepared for light microscopy. We recorded the reproductive condition of females (diameter of enlarged ovarian follicles =EOF) and found large aggregates of sperm within the spermathecae during all months, except February (no specimens available). The highest incidence of sperm in spermathecae occurred in July specimens (53%; n = 17). Although the known nesting season runs from July into August in this …

Abnormalities In The Ozark Hellbender, (Cryptobranchus Alleganiensis Bishopi) In Arkansas: A Comparison Between Two Rivers With A Historical Perspective, Waylon R. Hiler, Benjamin A. Wheeler, Stanley E. Trauth
Abnormalities In The Ozark Hellbender, (Cryptobranchus Alleganiensis Bishopi) In Arkansas: A Comparison Between Two Rivers With A Historical Perspective, Waylon R. Hiler, Benjamin A. Wheeler, Stanley E. Trauth
Journal of the Arkansas Academy of Science
We documented abnormalities of Ozark hellbender (Cryptobranchus alleganiensis bishopi) populations in the Eleven Point River (Randolph County, Arkansas) and the Spring River (Fulton County, Arkansas) as part of ongoing monitoring efforts in this species. We found abnormalities in 90% (9 of 10) and 40% (36 of 97) of hellbenders in the Spring River and Eleven Point River, respectively, during the 2003-2004 field seasons. Most abnormalities found in Eleven Point hellbenders were generally less invasive and seemed to be more intrinsic to the species' natural history (i.e., vicissitudes of living), whereas those found in Spring River hellbenders were gross morphological aberrations. …
Status Survey Of The Arkansas Endemic Crayfish, Fallicambarus Gilpini Hobbs And Robinson, Henry W. Robison, Brian K. Wagner
Status Survey Of The Arkansas Endemic Crayfish, Fallicambarus Gilpini Hobbs And Robinson, Henry W. Robison, Brian K. Wagner
Journal of the Arkansas Academy of Science
Fieldwork was conducted during 2002-2003 on the rare, Arkansas endemic crayfish, Fallicambarus gilpini Hobbs and Robison. Collections at 87 localities revealed this crayfish at 8 sites, all located in southeastern Arkansas in Jefferson and Cleveland counties which significantly expands its known range. Fallicambarus gilpini was generally found inhabiting roadside ditches and areas of standing water where it was always taken from upslope areas away from the static water. A sex ratio of 1:1.3 males to females was determined for this species. Ovigerous females were collected from burrows on 20 March 2003. A conservation status of "threatened" is recommended for this …
Songbird Inventory For Arkansas Post National Memorial, Philip A. Tappe
Songbird Inventory For Arkansas Post National Memorial, Philip A. Tappe
Journal of the Arkansas Academy of Science
Two geographically separate units of Arkansas Post National Memorial were surveyed via fixed-radius plots to document songbird species composition, richness, and diversity by migratory status and nesting guild. At the Memorial Unit, 60 species vere recorded with the Brown-headed Cowbird, Red-winged Blackbird, and Northern Cardinal being most common. individuals of these three species comprised 30% of the total number of birds recorded despite representing only 5% of the species encountered. About 2 1/2 times more resident birds were recorded than migratory birds. However, species richness and diversity of resident and migratory species were similar. The number of individuals, species richness, …
Annotated Checklist Of The Amphipoda Of Arkansas With Emphasis Upon Groundwater Habitats, G. O. Graening, Michael E. Slay, John R. Holsinger
Annotated Checklist Of The Amphipoda Of Arkansas With Emphasis Upon Groundwater Habitats, G. O. Graening, Michael E. Slay, John R. Holsinger
Journal of the Arkansas Academy of Science
Based on recent collections and review of the literature, 20 species of freshwater amphipod crustaceans are listed from the state of Arkansas. Included are species from the families Allocrangonyctidae, Crangonyctidae, Gammaridae and Hyalellidae and the genera Allocrangonyx, Bactrurus, Crangonyx, Stygobromus, Gammarus, and Hyalella. Ten of the species are restricted to subterranean groundwaters, 2 are closely associated with groundwater but also occur in surface waters, and 8 are known primarily from surface waters. Two of the species are in the process of being described in the literature, whereas 2 remain only provisionally recognized to date. On the basis of this new …
Distribution And Status Of The Kiamichi Shiner, Nottropis Ortenburgeri Hubbs (Cyprinidae), Henry W. Robison
Distribution And Status Of The Kiamichi Shiner, Nottropis Ortenburgeri Hubbs (Cyprinidae), Henry W. Robison
Journal of the Arkansas Academy of Science
The Kiamichi shiner, Notropis ortenburgeri, a diminuitive, silvery, upland stream fish in southwestern Arkansas and eastern Oklahoma was studied from 1999-2001 to determine its distribution, habitat, and conservation status in Arkansas and Oklahoma. Eighty-five collections were made during the two-year study. The present distribution in Arkansas and Oklahoma is described as well as the conservation status of the Kiamichi shiner in both states.
