Dynamics Of Wild Red Raspberry (Rubus Idaeus L.) And The Influence On Tree Regeneration Within Silvicultural Openings In A Northern Hardwood Stand, Matthew J. Widen
Dynamics Of Wild Red Raspberry (Rubus Idaeus L.) And The Influence On Tree Regeneration Within Silvicultural Openings In A Northern Hardwood Stand, Matthew J. Widen
Dissertations, Master's Theses and Master's Reports
Previous studies have investigated how the abundance of raspberries (Rubus idaeus L.) impacts tree regeneration, but few have linked these impacts to location within canopy openings with a legacy tree. To fill this knowledge gap, we investigated the presence, abundance, and location of raspberries within openings containing legacy trees and the resulting impacts on tree regeneration. During the winter of 2003, 49 openings were created of three sizes: small, medium, large and 20 reference single-tree selection sites in a northern hardwood stand in Ford Forest near Alberta, Michigan. Tree regeneration and vegetative species cover were recorded in 2005 and …
Methane Fluxes And Porewater Dissolved Organic Carbon Dynamics From Different Peatlands Types In The Pastaza-Marañon Basin Of The Peruvian Amazon., Jhon Del Aguila-Pasquel
Methane Fluxes And Porewater Dissolved Organic Carbon Dynamics From Different Peatlands Types In The Pastaza-Marañon Basin Of The Peruvian Amazon., Jhon Del Aguila-Pasquel

Relevant components of the carbon budget such as methane fluxes and porewater dissolved organic carbon (DOC) are poorly characterized in the Peruvian Pastaza Marañon basin (PMB). PMB is associated with a tropospheric hotspot for methane and therefore it may represent a significant methane source. We aimed to quantify the magnitude of CH4 fluxes and porewater DOC; and to determine their predictors across different peatland types in the PMB (open peatland, palm swamp, and pole forest). The study was conducted in two peatland sites covering the three main vegetation types in PMB. We collected gas and water samples using chamber-based …

Active remote sensing technology (LiDAR) and passive remote sensing technology (Pleiades and Göktürk-2 satellites) were used to find a meaningful relationship between ground data and remote sensing instruments for Istanbul Forest, Turkey. Two dominant species in the field, oak (deciduous trees) and maritime pine (coniferous trees), were researched. There were 86 plots total, 41 for maritime pine and 45 for oak. Three diameter at breast height (DBH) thresholds were studied. Trees of any DBH (DBH≥0.1 cm), trees ≥8 cm DBH thresholds and, trees ≥10 cm DBH thresholds. Both satellite image metrics were derived from Grey Level Co-occurrence Measures (GLCM). All …
The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens
The Effects Of Early Pruning On The Near-Ground Branch Density Of Four Live Fencing Species, Aric Devens

Crop losses in home gardens greatly impact the wellbeing of rural West African families. Herbivory by migratory or local livestock represents a significant source of crop loss. Live-fencing gardens with thorny hedges is a low-cost and sustainable strategy for reducing losses due to herbivory. However, guidance on the establishment of thorny hedges is inconsistent, poorly publicized, and often anecdotal. Therefore, this study evaluated the effects of three early pruning treatments on near-ground branch density of four thorny species: Vachellia nilotica, Senegalia laeta, Senegalia mellifera, and Prosopis juliflora. Physical measurements and photographic data indicated that after one growing season, V. …
Development Of Gene-Based Microsatellite Markers In Acer Saccharum Marsh., Monica Harmon
Development Of Gene-Based Microsatellite Markers In Acer Saccharum Marsh., Monica Harmon
Dissertations, Master's Theses and Master's Reports
Sugar maple (Acer saccharum Marsh) is an important ecological and economic resource. Despite its significance, there are few molecular genetic resources available to date. This study used previously developed EST libraries generated for sugar maple and other hardwood species to develop and characterize EST-SSRs in sugar maple and test their transferability to other Acer species. Out of 58 markers tested, 22 showed amplification in the expected size range. From these, 16 polymorphic markers were selected to test transferability and 13 of these showed amplification in at least one other Acer species.
