Evaluating Post-Fire Plantation Restoration In A Mixed Conifer Forest In The Sierra Nevada, Iris C. Allen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Forests in the western United States have experienced a shift from historical disturbance regimes in the past century. Many of these changes were induced by European settlers logging the forests and suppressing fires. In the past, the dry mixed conifer forests of California’s Sierra Nevada mountains experience frequent, low to mixed severity fires. This fire regime helped maintain a heterogeneous landscape comprised of groups of trees and openings. However, due to fire suppression and high grading logging, forest structure has changed; there are less openings and more small, fire-intolerant trees that can carry a fire into the forests crown. The …

Quantifying The Morphological And Physiological Effects Of Drought, Grass Invasion, And Fire On Longleaf, Loblolly, And Slash Pine, Laura Young
College of Graduate Studies: Theses & Dissertations
Climate change is altering ecosystems on a global scale, creating novel ecological scenarios with which plant species must cope. Factors such as altered precipitation and fire regimes and non-native plant invasion may negatively affect native plant species, while interactions between these stressors could magnify their impacts. The complexity of multiple stressors and the effects they have on native pine seedlings are difficult to predict without evaluating their combinations in field experiments. In a multi-year study, I investigated the effects of drought and plant invasion on three southeastern pine species under pre and post-fire conditions. We planted longleaf (Pinus palustris …

Effects Of Disturbance On Jack Pine- (Pinus Banksiana Lamb.) Dominated Ecosystems In Northern Lower Michigan: Forest Management, Wildfires, And Climate Change, Madelyn Tucker
Wayne State University Dissertations
Jack pine-dominated forests in northern Lower Michigan were historically characterized by a frequent, severe fire regime that produced a patchwork of dense stands interspersed with open barrens. This structure also provided breeding habitat for Kirtland’s warblers, a migratory songbird. Fire suppression management caused forests to become older and reduced Kirtland’s warbler habitat, resulting in severe population losses. Kirtland’s warblers were designated as endangered, and subsequent habitat management has produced homogeneous forests that lack historical structural and compositional diversity. Moreover, future climate may increasingly complicate forest and fire management moving forward. In a landscape defined by disturbance, novel disturbances or changes …

Turkish Journal of Agriculture and Forestry
Several citrus varieties produce apomictic seeds by the nucellar embryony (NE) mechanism. Nucellar embryos are created from nucellus tissue and have an identical genetic constitution to the mother plant. Nucellar embryony is known to be an unusual feature of seed production in many citrus cultivars. The term "NE" refers to the development of identical embryos from the maternal tissue known as the nucellus surrounding the embryo sac. The authors aimed here to detect differentially expressed genes involved in the NE mechanism. Orlando tangelo (OT), producing apomictic seeds, and a clementine mandarin, Algerian tangerine ranch selection (AT), known as monoembryonic, were …

Turkish Journal of Agriculture and Forestry
Soil compaction is a great problem since it affects crop growth and yield. The causes of soil compaction are the management practices in agricultural production. A common practice is to implement subsoiling at a few centimeters below the hardpan. Management practices, field traffic, and variations of the soil?s physical and chemical properties throughout the field cause variations in the soil compaction degree and depth. Subsoiling at certain depths can cause excessive energy consumption at a high cost. Therefore, agricultural tillage equipment could be improved by varying the tillage depth. Soil strength is the main indicator that depends on several soil …
