Post‐fire bryophyte establishment in a continental bog

Endozoochory by slugs can increase bryophyte establishment and species richness

Herbivory can aff ect plant community composition and diversity by removing biomass and reducing light competition. Herbivory may particularly benefi t low growing species such as bryophytes, which are frequently limited by light competition. Gastropods are important herbivores of seed plants and cryptogams, furthermore, they can disperse propagules such as seeds and spores via endozoochory. Ho...

White Spruce Meets Black Spruce: Dispersal, Postfire Establishment, and Growth in a Warming Climate

Local distributions of black spruce (Picea mariana) and white spruce (Picea glauca) are largely determined by edaphic and topographic factors in the interior of Alaska, with black spruce dominant on moist permafrost sites and white spruce dominant on drier upland sites. Given the recent evidence for climate warming and permafrost degradation, the distribution of white spruce is expected to expa...

Abiotic Stresses to Vegetation Re-establishment in a Cutover Bog Contaminated with Seawater

I hereby declare that I am the sole author of this thesis. This is the true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. Abstract Part of a cutover bog in Pokesudie Island, New Brunswick, Canada was contaminated with seawater and was still largely devoid of vegetation 5 ye...

Postfire Plant Establishment: The Effects of Environment, Prefire Vegetation, Fire Severity, and Landscape Position

Postfire logging in riparian areas.

We reviewed the behavior of wildfire in riparian zones, primarily in the western United States, and the potential ecological consequences of postfire logging. Fire behavior in riparian zones is complex, but many aquatic and riparian organisms exhibit a suite of adaptations that allow relatively rapid recovery after fire. Unless constrained by other factors, fish tend to rebound relatively quick...
