Landscapes Are Cornerstones Of Sustainability Programs, Don Spence

Sustainability Conference

Typical American landscapes are not sustainable in an economic or biological framework. The essence of the idea of sustainable growth and development are centered on the idea that those activities are not degrading natural resources or that they are outstrip budgets. A significant piece of any sustainable management plan is tied to how we manage our landscapes, how we use plants; specifically, how much grass there is, and how many native plants there are. Sustainable landscapes should require less chemical and financial inputs, which in the end, saves money and increases the biological value of the land and creates a …

Mule Deer Impede Pando’S Recovery: Implications For Aspen Resilience From A Single-Genotype Forest, Paul C. Rogers, Darren J. Mcavoy

Ecology Center Publications

Aspen ecosystems (upland Populus-dominated forests) support diverse species assemblages in many parts of the northern hemisphere, yet are imperiled by common stressors. Extended drought, fire suppression, human development, and chronic herbivory serve to limit the sustainability of this keystone species. Here we assess conditions at a renowned quaking aspen (Populus tremuloides) grove—purportedly the largest living organism on earth—with ramifications for aspen biogeography globally. The “Pando” clone is 43 ha and estimated to contain 47,000 genetically identical aspen ramets. This iconic forest is threatened in particular by herbivory, and current management activities aim to reverse the potential for …

BIO 255 Conservation Biology

The Salve Regina University Arboretum, located in Newport, Rhode Island is currently registered as a Level II arboretum and is intertwined with the city of Newport Arboretum. The university now has intentions to reach Level III status, as part of a ten-year plan. This plan was developed by the students of the Spring 2018 BIO 255: Conservation Biology course, instructed by Dr. Jameson Chace, Associate Professor of biology at Salve Regina University. As part of a curriculum geared towards civic engagement, the class focused on creating and optimizing strategies that can be applied to the ten-year plan. These strategies were …

Toward An Improved Conceptual Understanding Of North American Tree Species Distributions, Paige E. Copenhaver-Parry

Faculty Publications - Department of Biological & Molecular Science

Species distributions have often been assumed to represent climatic limitations, yet recent evidence has challenged these assumptions and emphasized the potential importance of biotic interactions, dispersal limitation, and disturbance. Despite significant investigation into these factors, an integrated understanding of where and when they may be important is lacking. Here, we review evidence for the factors underlying the historical and contemporary distributions of North American tree species and argue that a cohesive conceptual framework must be informed by an understanding of species ecological and evolutionary history. We further demonstrate that available evidence offers little indication of a significant, independent influence of …

Temporal Fluctuation Scaling In Populations And Communities, Michael Kalyuzhny, Yishai Schreiber, Rachel Chocron, Curtis H. Flather, Ronen Kadmon, David A. Kessler, Nadav M. Shnerb

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Taylor’s law, one of the most widely accepted generalizations in ecology, states that the variance of a population abundance time series scales as a power law of its mean. Here we reexamine this law and the empirical evidence presented in support of it. Specifically, we show that the exponent generally depends on the length of the time series, and its value reflects the combined effect of many underlying mechanisms. Moreover, sampling errors alone, when presented on a double logarithmic scale, are sufficient to produce an apparent power law. This raises questions regarding the usefulness of Taylor’s law for understanding ecological …

Five Year Carbon Storage Analysis In The Gordon Natural Area, Joy Fritschle, Chad Hudson, Catherine Spahr, Andy Tamez

Forest Carbon Storage Study Documents

The Gordon Natural Area (GNA) serves as a natural laboratory for a range of class research projects. In a Geography Field Methods course led by Dr. Fritschle, students established five permanent carbon-study plots in 2008. Since then, students have returned to these plots to measure the carbon stock of standing trees in five plots located along a topographic gradient: floodplain, ridge-top, lower mid-slope, mid-slope and upper mid-slope. Using U.S. Forest Service established guidelines, all trees greater than 5 cm and up to 73 cm in diameter at breast height (DBH) were measured and identified within each 40 m circular plot. …

Variations In Stomatal Traits Of 14 Bornean Tree Species Growing On Soils With Different Moisture Contents In Lambir Hills National Park, Whitney Logan Cannon

Department of Environmental Studies: Undergraduate Student Theses

The goal of this study was to look at variations in stomatal traits of tree species on soils with different moisture contents and fertility at Lambir Hills National Park. Stomates are important structures on the surface of leaves that mediate conduction of moisture and gassesin and out of the leaf. If stomatalt raits are important for regulation, then there should be variation in stomatal traits in regards to their soil specialization.

Topographic Factors Affecting The Tree Species Composition Of Forests In The Upper Piedmont Of Virginia, Rachael C. Brown, Todd S. Fredericksen

Virginia Journal of Science

There are many factors that influence forest species composition and many are linked to topographical features. This study, conducted on the Ferrum College campus in the Upper Piedmont Physiographic Province of Virginia revealed three major forest types associated with topographic factors using cluster analysis and detrended correspondence analysis . The first type of forest occurred mostly on northeastern slopes on toe slope topographic positions and was mainly composed of tulip tree (Liriodendron tulipifera) and red maple (Acer rubrum). The second type of forest was found on shoulder and side slope positions and was composed mostly of …

Forest Stand Dynamics, Update Edition, Chadwick Dearing Oliver, Bruce A. Larson

Yale School of the Environment Other Publications

This book describes the various growth patterns of forests from a mechanistic point of view. Its purpose is to help silviculturists, forest managers, and ecologists understand and anticipate how forests grow and respond to intentional manipulations and natural disturbances. Demands on the forest have been increasing for timber production, wildlife habitat, water protection, recreation, and protection from fires, insects, and diseases. These demands have created an emphasis on prescribing site-specific treatments for individual stands of trees, rather than treating broad areas uniformly

Bulletin 4274 - Tree Planting On The High Rainfall Coastal Plain, Don Bennett, Richard George

Bulletins 4000 -

Careful planning can mean the difference between the success or failure of a tree planting program . Healthy , well-e stablished trees stand a better chance of survival, grow faster and are more resistant to insect attack. The need for time-consuming watering in summer is also eliminated.

The high rainfall coastal plain extends from Perth to Busselton and inland to the Darling Scarp. It receives about 800 to 1000 mm annual rainfall.

Site preparation is ideally started in summer. For a winter planting, decide before March where to plant, which varieties and how many trees to plant. Early planning allows …

THE group of beetles commonly known as weevils contains some of the most troublesome of all insect pests.

The best known is probably the wheat weevil, but many other forms attack stored products and growing plants.

Insect Pests Of Forests. 2. Tussock Moths And Bag-Shelter Moths, Clee Francis Howard Jenkins

Journal of the Department of Agriculture, Western Australia, Series 4

TWO native caterpillars which sometimes attract attention are the larvae of the tnssock moth and the bag-shelter moth.

Neither insect is a serious forest pest in Western Australia, but the tussock moth sometimes does restricted damage in orchards and home gardens and the bag-shelter caterpillars cause some defoliation of wattles and eucalyptus.

Trees And Shrubs Of Kings Canyon National Park, Kenneth M. Stocking

University of the Pacific Theses and Dissertations

In 1935 I first visited the Kings Canyon area. Since then I have spent many hours wandering through the woods and over the mountains in the area around the old General Grant National Park and the country which is now included in the Kings Canyon National Park. To my knowledge, no complete flora has been made for this vicinity. I consider the following pages to be the beginning of a fascinating work. It is the beginning because this paper includes only plants with woody stems.
