Historical Reflections On The Arkansas Cross Timbers, Don C. Bragg
Historical Reflections On The Arkansas Cross Timbers, Don C. Bragg
Journal of the Arkansas Academy of Science
Kiichler's original map of potential natural vegetation suggested that the eastern-most extension of the "Cross Timbers" oak-dominated woodland reached into extreme western Arkansas. Recent investigations have found possible old-growth Cross Timber communities in narrow strips along steep, rocky sandstone and shale ridges near Fort Chaffee and Hackett. However, many decades of Euroamerican intervention have altered vegetation composition and structure in west-central Arkansas, making field evaluation difficult. Fortunately, historical accounts of the area provide considerable supporting documentation. General Land Office surveyors, for instance, traversed this portion of western Arkansas before 1850. They reported many ridges and slopes dominated by grassy, stunted …
Western Kingbird (Tyrannus Verticalis): Recently Established Breeding Bird In Arkansas, Elizabeth Ellis, Ragupathy Kannan
Western Kingbird (Tyrannus Verticalis): Recently Established Breeding Bird In Arkansas, Elizabeth Ellis, Ragupathy Kannan
Journal of the Arkansas Academy of Science
The Western Kingbird (Tyrannus verticalis) has nested for six consecutive years in Arkansas since 1998. Eleven nests of this species were observed in the summer of 2003 in urban areas of Fort Smith (Sebastian Co.) and Van Buren (Crawford Co.). All nests were on human-made structures. Of the 11, seven (64%) were located on power stations and the remaining four (36%) were on light posts. Mean nest height was 7.92 m (n = 11nests) and the mean width of nest poles was 31.18 cm (n= 4). Nest building lasted 12 to 13 days (mean = 12.5 days, n = 2 …
Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe
Assessment Of Thermal Infrared Detection Rates Using White-Tailed Deer Surrogates, Robert E. Kissell Jr., Philip A. Tappe
Journal of the Arkansas Academy of Science
As thermal infrared imaging technology has improved, it has increasingly been used for estimating sizes of wildlife populations. The greatest bias of thermal infrared surveys is the lack of known detection rates to adjust for visibility bias. As with visual surveys, a measure of detection rate is needed to provide unbiased estimates. We assessed the detection rate of white-tailed deer (Odocoileus virginianus) using a thermal infrared sensor (1.2 - 5.9 /an) from an aerial platform. Similar characteristics between thermal signatures of people and deer allowed us to use people in a reclined or horizontal position as surrogates for deer. We …
Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse
Human Rabies Post-Exposure Treatment In Arkansas, 1994-2000, D. Blake Sasse
Journal of the Arkansas Academy of Science
The Arkansas Department of Health recorded 118 incidents where humans in Arkansas were treated following exposure to confirmed rabid animals from 1994-2000. Domestic species accounted for 64% of incidents and 76% of total human exposures with the ratio of human exposures per rabid animal 17 times higher for domestic animals than wild animals. Records of 218 cases of human exposure to potentially rabid wild animals during this period were also examined to determine method of contact. While 72% of cases involving raccoons (Procyon lotor), skunks (Mephitis mephitis and Spilogale putorius), and foxes (Urocyon cinereoargenteus and Vulpes vulpes) were initiated by …

Distribution, Natural History Aspects, And Status Of The Arkansas Endemic Crayfish, Fallicambarus Harpi Hobbs And Robinson, 1985, Henry W. Robison, Betty G. Crump
Distribution, Natural History Aspects, And Status Of The Arkansas Endemic Crayfish, Fallicambarus Harpi Hobbs And Robinson, 1985, Henry W. Robison, Betty G. Crump
Journal of the Arkansas Academy of Science
Recent fieldwork in west central Arkansas has revealed the Arkansas endemic crayfish, Fallicambarus harpi Hobbs and Robison, to be more abundant than formerly believed. New localities and county records are provided in addition to information on the habitat preferences, sex ratio, color variation, reproductive biology, and conservation status of this burrowing crayfish.

Additions To The Aquatic Diptera (Chaoboridae, Chironomidae, Tabanidae, Tipulidae) Fauna Of The White River National Wildlife Refuge, Arkansas, Stephen W. Chordas Iii, Patrick L. Hudson, Eric G. Chapman
Journal of the Arkansas Academy of Science
The dipteran fauna of Arkansas is generally poorly known. A previous study of the Aquatic macroinvertebrates of the White River National Wildlife Refuge, the largest refuge in Arkansas, reported only 12 diptera taxa out of 219 taxa collected (Chordas et al., 1996). Most of the dipterans from this study were identified only to the family level. The family Chironomidae is a large, diverse group and was predicted to be much more diverse in the refuge than indicated by previous studies. In this study, Chironomidae were targeted, with other aquatic or semiaquatic dipterans also retained, in collections designed to better define …
Stand-Level Green Biomass Equations For Sawtimber-Sized Loblolly Pine In Arkansas, Paul F. Doruska, David W. Patterson, Travis E. Posey
Stand-Level Green Biomass Equations For Sawtimber-Sized Loblolly Pine In Arkansas, Paul F. Doruska, David W. Patterson, Travis E. Posey
Journal of the Arkansas Academy of Science
Loblolly pine (Pinus taeda L.) is commercially the most important timber species in southern Arkansas and the southern United States. Results of stand-level timber inventories have traditionally been reported in terms of volume, yet loblolly pine sawtimber is bought and sold based on biomass. A straight forward stand-level conversion from volume per hectare to biomass per hectare does not exist for Arkansas, thus complicating the valuation of standing loblolly pine sawtimber. Two equations were developed to predict stand-level, outside-bark, green biomass per unit area for loblolly pine stands in southern Arkansas. The merchantable sawlog equation presented herein explained approximately 95% …
