Disturbance regimes within temperate forests can significantly impact carbon cycling. Additionally, projected climate change in combination with multiple, interacting disturbance effects may disrupt the capacity of forests to act as carbon sinks at large spatial and temporal scales. We used a spatially explicit forest succession and disturbance model, LANDIS-II, to model the effects of climate change, gypsy moth (Lymantria dispar L.) defoliation, and wildfire on the C dynamics of the forests of the New Jersey Pine Barrens over the next century. Climate scenarios were simulated using current climate conditions (baseline), as well as a high emissions scenario (HadCM3 A2 emissions ...

Mitigation Site Soil Characteristics And The Effects Of Inoculation, Nursery Fertilizer Practices And Irrigation On Survival And Growth Of Mesquite (Prosopis Glandulosa) In The Coachella Valley, California, David A. Bainbridge, Marcelle M. Darby

David A Bainbridge

Prosopis glandulosa var. torreyana (mesquite, honey mesquite) is a small to medium sized leguminous tree that was once common in the low desert of California. Widespread destruction of mesquite woodlands in the Coachella Valley of southern California for fuel wood, agricultural and urban development, and urbanization has reduced once vast stands to isolated remnants. The rerouting and widening of Highway 86 in the Coachella Valley was a typical example of ongoing mesquite woodland removal. Despite the recognized need for mitigation, relatively little information on mesquite establishment in California is available. This research explored mesquite establishment by replanting on an abandoned ...

Review: Pollination, Pollinated And Pollinators Interaction In Pakistan, Mohammad Irshad, Elizabeth Stephen

Journal of Bioresource Management

The agriculture sector is important in the overall economy and export earnings of Pakistan. Pollination is an essential ecosystem service that depends on symbiosis between species, the pollinated and the pollinator. Animal mediated pollination contributes to the sexual production of over 90% species of modern angiosperms. Effective pollination results in increased crop production, quality improvement and more seed production. Many fruits, vegetables, edible oil crops, stimulant crops and nuts are highly dependent on bee pollination. Worldwide value of pollinators is €153 billion (217 billion US dollars). The production value of pollinated dependent crop in Pakistan is quantified to be 1 ...

Project Report No. 69, Observed Growth And Yield Of Loblolly And Slash Pine Plantations In East Texas, Dean W. Coble, Katherine Pendergast

Informal Project Reports

Forestland in East Texas is an estimated 12.1 million acres, with approximately 2.9 million acres (24%) classified as pine plantations on private land. Because pine plantations are typically managed for timber production, information regarding tree growth is needed to make informed management decisions. An understanding of how growth factors such as tree volume, diameter, height and basal area are affected by site index, trees per acre and age in East Texas enables plantation managers to make the management decisions necessary to maximize timber production.


Effect Of Australian Pine (Casuarina Equisetifolia) Canopy Density On The Understory Plant Community On San Salvador, Bahamas, Jeffry Anderson, Anna Baumgartner 2014 College of Saint Benedict and Saint John’s University

Effect Of Australian Pine (Casuarina Equisetifolia) Canopy Density On The Understory Plant Community On San Salvador, Bahamas, Jeffry Anderson, Anna Baumgartner

Celebrating Scholarship & Creativity Day

Casuarina equisetifolia, or Australian pine, is an invasive angiosperm species on the island of San Salvador, The Bahamas. It was originally found only in Southeast Asia and Australia. This tree is unique in that its leaves are much reduced and occur in whorls around the photosynthetic branchlets. It has been established that this tree contributes to the increased erosion of sediment on the dunes of San Salvador (Sealey 1998). This study investigated several possible factors contributing to differences in the understory plant community which may contribute to this erosion including leaf litter density, shading, and soil pH. It is hypothesized ...
