Campus Life: In Perkins Arboretum There Are Birds Of All Feathers, Trees That Tell A Story, And Even Romance (Especially If You're A Frog), Gerry Boyle
Colby Magazine
To the uninitiated, Perkins Arboretum is the edge of campus. For those familiar with its flora and fauna, the arboretum is a wondrous classroom and refuge.

Sequoiadendron Giganteum (Cupressaceae) At Lake Fulmor, Riverside County, California, Rudolf Schmid, Mena Schmid
Aliso: A Journal of Systematic and Floristic Botany
A GPS census made on 19 June 2012 of the Lake Fulmor area, northwestern San Jacinto Mountains, Riverside County, California, revealed seven trees of the Sierra Nevada endemic Sequoiadendron giganteum (Cupressaceae). The trees occur in a 234-meter-long narrow strip along the northwestern side of the lake. The population appears to be naturalizing. The largest tree (45 cm DBH, about 20 m tall), planted in 1980, is reproductively mature. Its six offspring to the northeast and southwest are 3–5 m tall and do not presently bear cones.

Community, Culture And Identity In An Age Of Globalization, Katie Wiggins
Occam's Razor
As we move further into the age of globalization, we are seeing changes not only at a global level but at individual and communal levels; changes that we cannot wholly identify but that we recognize in ourselves. We are adapting to a global world, one that is affecting our identity and culture and, as we attempt to hold on to this identity and still converse with a larger world, we ultimately are forced to reshape our identities. Some may wonder what this will mean for the future and to what extent it affects us as individuals and communities. To answer …

Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard
Relationship Between Land-Use And Water Quality In Spring-Fed Streams Of The Ozark National Forest, A. Smartt, S. Ganguly, M. A. Evans-White, B. E. Haggard
Journal of the Arkansas Academy of Science
Spring-fed streams are abundant in karst topographic regions such as the Ozarks, providing an important and valuable water resource. Many of these spring-fed streams presently receive agriculture runoff, but few studies have examined the impacts of this runoff on water quality. We examined water quality in Ozark spring-fed streams surrounded by either agricultural (N=3) or primarily forested land (N=3) in the riparian zone. We hypothesized that agricultural sites would have greater dissolved nutrient concentrations and conductivity than forested sites and that water quality would fluctuate with distance from the spring source. Conductivity (p

Distribution Of Soil Density At A Bottomland Hardwood Forest Wetland Restoration, Chicot County, Arkansas, B. E. Sleeper, Robert L. Ficklin
Journal of the Arkansas Academy of Science
Bottomland hardwood forest (BLHF) soils provide a myriad of ecosystem services, yet much information is lacking with respect to how soil physical properties influence biogeochemical cycling along topographic gradients. Current patterns of vegetation at a 149ha wetland restoration site in Chicot County, Arkansas, suggest the presence of ecologically significant variation in soil properties within the Perry Clay soil series. A study was initiated in the Lower Mississippi Alluvial Valley (LMAV) to map soil bulk density and texture as well as to identify the interrelationships between soil physical properties, soil organic carbon, and total nitrogen. A random grid was used to …
Deriving Biomass Models For Small-Diameter Loblolly Pine On The Crossett Experimental Forest, K. M. Mcelligot, Don C. Bragg
Deriving Biomass Models For Small-Diameter Loblolly Pine On The Crossett Experimental Forest, K. M. Mcelligot, Don C. Bragg
Journal of the Arkansas Academy of Science
Foresters and landowners have a growing interest in carbon sequestration and cellulosic biofuels in southern pine forests, and hence need to be able to accurately predict them. To this end, we derived a set of aboveground biomass models using data from 62 small-diameter loblolly pines (Pinus taeda) sampled on the Crossett Experimental Forest in southeastern Arkansas. Of the 25 equations initially evaluated, we chose 17 that best fit our dataset and compared them using a suite of conventional test statistics, including pseudo-R2 , root mean squared error (RMSE), and bias. Because most of the 17 models varied little in pseudoR …

Comparing Aboveground Biomass Predictions For An Uneven-Aged Pine-Dominated Stand Using Local, Regional, And National Models, Don C. Bragg, K. M. Mcelligott
Journal of the Arkansas Academy of Science
Sequestration by Arkansas forests removes carbon dioxide from the atmosphere, storing this carbon in biomass that fills a number of critical ecological and socioeconomic functions. We need a better understanding of the contribution of forests to the carbon cycle, including the accurate quantification of tree biomass. Models have long been developed to predict aboveground live tree biomass, but few of these have been derived from Arkansas forests. Since there is geographic variability in the growth and yield of pine as a function of genetics, site conditions, growth rate, stand stocking, and other factors, we decided to compare aboveground tree biomass …
