Disturbance impacts on non-native plant colonization in black spruce forests of interior Alaska
… historically been relatively free from invasive plants, there have been recent increases in the diversity and range of invasive plants in Alaska. It is critical that we understand how disturbances influence invasibility in northern boreal forests, to avoid the economic damage other regions have …

Carbon metabolism and dissolved organic carbon (DOC) fluxes on seagrass communities: insights from plant colonization states, eutrophication and global change related factors
Coastal vegetated communities are among the most productive ecosystems on Earth. Their role in the global carbon cycle and how they cope with global change may be more relevant than previously believed. They export large quantities of matter, both in particulate and dissolved forms to adjacent …

Changes in avian diversity and potential invasive seed dispersal post-wildfire in a Southeastern deciduous forest; Flipper Bend Woods, Signal Mountain, Tennessee
… thought to have been worsened by invasive plants. In order to examine post-fire recovery and invasive plant recolonization, researchers observed the diversity of avian species in a burned and unburned site. Using mist-nets, line-transects, and vegetation analysis, this study found that …

The in planta role of the global regulator Lrp in the bacterial phytopathogen Pantoea stewartii subsp. stewartii
… flea beetle, transmits P. stewartii into corn plants through wounds in the leaves. The bacteria can then move to the xylem of the plant where they form a biofilm that inhibits the flow of water. A previous in planta RNA-Seq study resulted in the selection of lrp as a gene of interest for …

Community and ecosystem analysis of forests recovering from landslide disturbance: White Mountain National Forest, New Hampshire
… that of the surrounding forest. Consequently, plant colonization and community succession differ from less severely disturbed sites such as timber harvest or agricultural afforestation.</p><p>Two chapters of this dissertation address the unique conditions of landslide ecosystem development. …

A FAMILY OF SMALL SECRETED PROTEINS FROM RHIZOPHAGUS IRREGULARIS CONTRIBUTE TO ARBUSCULAR MYCORRHIZA SYMBIOSIS
… are able to colonize more than 80% of all land plants, providing several benefits to their host, such as an increased nutritious status or an increased resistance to pathogens. The molecular mechanisms underlying plant colonization are still unknown, due to the lack of molecular tools to …

Complementary approaches to integrate microbial diversity into revegetation and phytoremediation on abandoned mine tailings
… disposal sites are characterized by a reduced plant colonization and a compromised heterotrophic microbial community. Ecological restoration has emerged as a primary objective for the development of stable and productive ecosystems in mining areas. In this context, microorganisms are pivotal …

Plant Successional Patterns at Sperry Glacier Foreland, Glacier National Park, MT, USA
… of glacier forelands. Patterns of plant colonization and succession on terrain exposed by retreating glaciers give insight into factors influencing alpine ecosystem change and recovery. Understanding these patterns and processes is important for conserving alpine landscapes and …

Evaluation of Host Resistance and the Utilization of Organic Amendments to Manage Macrophomina Crown Rot of Strawberry in California
… can be severely limited by soilborne plant pathogens, insects and weeds. <em>Macrophomina phaseolina </em>is a problematic soilborne fungal pathogen in California strawberry production inciting the disease Macrophomina crown rot. When established, the pathogen can cause extensive plant …

Carex establishment on reclaimed oil sands landscapes : a case study at Suncor Energy Inc.
… oil sands landscapes are perceived to be low in plant diversity compared with naturally occurring plant communities. Approximately 66 Carex species inhabit the oil sand region. This thesis is unique and represents the first large scale study of Carex establishment on reclaimed oil sands …
