Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown Jan 1994

Aquatic Macrophytes Of Two Small Northwest Arkansas Reservoirs, John J. Sullivan, Arthur V. Brown

Journal of the Arkansas Academy of Science

Lake Fayetteville and Lake Wedington are small reservoirs of about the same size and age that are located in northwestern Arkansas. We collected macrophytes from eleven transects around each reservoir in the autumn of 1993. Justicia (waterwillow), Typha (cat-tail), Scirpus (bulrush), Potamogeton (pondweed), and Zannichellia (horned pondweed) occur in both reservoirs. Justicia occurs most commonly in both reservoirs. The macrophytes of Lake Wedington are organized in a characteristic zonation pattern with bands from shore toward open water of emergent, floating-leaved, then submersed macrophytes. Macrophyte zonation was not as evident in Lake Fayetteville because of the low occurrence of floating leaved …


Burying Beetle (Coleoptera: Silphidae, Nicrophorus) Surveys On Poteau Ranger District, Ouachita National Forest, Joseph C. Neal, M. Earl Stewart, Warren G. Montague Jan 1994

Burying Beetle (Coleoptera: Silphidae, Nicrophorus) Surveys On Poteau Ranger District, Ouachita National Forest, Joseph C. Neal, M. Earl Stewart, Warren G. Montague

Journal of the Arkansas Academy of Science

Surveys for American burying beetles {Nicrophorus americanus Oliver) were conducted in west-central Arkansas on Poteau Ranger District of the Ouachita National Forest in1992 and 1993. A total of 2450 Nicrophorus specimens were captured in1098 trap nights. The most frequently captured specimens were N. orbicollis, N. tomentosus, and N. pustulatus. One specimen of N. americanus was also captures. Other species of beetles were also trapped and identified in this survey. Habitats sampled were primarily well-drained uplands with proposed or recent harvests of shortleaf pine (Pinus echinata). It appears that these habitats may not harbor extensive populations of N. americanus onPoteau RD.


Nectar-Seeking Visits By Butterflies In A Tallgrass Prairie Remnant In Eastern Nebraska, Tanya Bray Jan 1994

Nectar-Seeking Visits By Butterflies In A Tallgrass Prairie Remnant In Eastern Nebraska, Tanya Bray

Biology Faculty Publications

Stolley Prairie, a tallgrass virgin prairie remnant in eastern Nebraska, was visited 20 times between May 25 and August 14, 1988. Fifty-two species offorbs were observed in bloom during this period. Twenty-seven species of butterflies were observed and 21 species made 262 nectar-seeking visits to 21 plant species. While numbers offorbs in bloom did not strongly correlate with numbers of butterflies present, peaks of butterfly occurrence appeared to follow peaks of blossom abundance. The number of plant species utilized by a species of butterfly ranged from one to nine. Plants with an abundance of nectar such as common milkweed and …
