A New Species

Adults of Odontocepheus rumbleseatus n.sp. are described, the second Odontocepheus species known from North America. An unusual, deep posterior depression on the notogaster easily separates this species from all others in the genus Odontocepheus. Specimens were collected from hardwood leaf litter and rotten wood. The known distribution is Illinois and West Virginia south to northern Florida. Additional characters for separating the North American species O. oblongus (Banks) from O. elongatus (Michael) in Europe are presented, and the presence of O. elongatus in North America is documented.

Abstract Big basal area factor (BAF) sampling techniques were investigated in a 70-year-old even-aged hardwood forest in northern West Virginia. Data collection procedures permitted the investigation of several small BAFs when employed with 12 big BAFs ranging from 55 to 300. Mean board foot volume per acre for sawtimber products was investigated along with a comparison of the resultant standard errors. The estimated mean volume per acre was quite stable. The same approximate mean volume per acre was obtained using big BAF values of 55 and 150 but with a 66% reduction in the number of sample trees needed for volume estimation. Sampling error increased with increasing big BAF, especially above values of 150. Sampling error within a single big BAF value was stable across the range of small BAFs sampled.

Trace Gas Fluxes

The response of trace gas fluxes (CO2, CH4, and N2O) and litter decomposition to increased soil temperature was evaluated in a northern hardwood forest. Four experimental plots (10 × 10 m) had heating cables installed within the forest floor. Temperatures at 5 cm were increased 2.5, 5.0, or 7.5°C in individual heated plots during the field season in 1993 and 1994. The fourth plot was a cabled, nonheated reference. Trace gas fluxes were monitored using closed chambers. Soil moisture was monitored using tensiometers and time domain reflectometry. Changes in leaf litter decomposition were quantified using litter bags for American beech (Fagus grandifolia Ehrh.) and sugar maple (Acer saccharum Marsh.) litter. Fluxes of CO2 increased exponentially with increased soil temperatures within treatments and were higher in heated plots than in the reference plot. Temperature coefficients (Q10) and mass remaining of American beech leaf litter decreased with the level of heating, suggesting a nonlinear microbial response to elevated temperatures. Soil water content exhibited the most influence on CH4 and N2O flux in the second season. The experimental manipulations showed the importance of evaluating the influence of soil temperature coupled with effects of N and moisture availability.

Abstract Zeide's (1993) two-point method for projecting volume growth was used to compare the predicted volume to a current intensive inventory of an Appalachian hardwood forest in northern West Virginia. Results indicate that the calculated growth type was stable and that the 8-year predicted volume was within 2% of the inventory estimate. North. J. Appl. For. 21(3):164–165.
