Ecological communities are increasingly being recognized as the products of contemporary drivers and historical legacies that are both biotic and abiotic. In an attempt to unravel multiple layers of ecological contingency, we manipulated (i) competition with exotic annual grasses, (ii) the timing of this competition (temporal priority in arrival/seeding times) and (iii) watering (simulated rain...
Understanding the genetics of lifetime fitness is crucial to understand a species' ecological preferences and ultimately predict its ability to cope with novel environmental conditions. Yet, there is a dearth of information regarding the impact of the ecological variance experienced by natural populations on expressed phenotypic and fitness differences. Here, we follow the natural dynamics of e...
Management decisions grounded in ecological understanding are essential to the maintenance of a healthy urban forest. Decisions about where and what tree species to plant have both short and long-term consequences for the future function and resilience of city trees. Through the construction of a theoretical damage index, this study examines the legacy effects of a street tree planting program ...
Ecological restoration projects have traditionally focused on vegetation as both a means (seeding, planting, and substrate amendments) and ends (success based upon primary productivity and vegetation diversity). This vegetation-centric approach to ecological restoration stems from an historic emphasis on esthetics and cost but provides a limitedmeasure of total ecosystem functioning and overloo...
Plant Population Dynamics and Conservation in Wooded Hay-Meadows – Effects of Intensified Management
List of papers This thesis is based on the following papers, which will be referred to in the text by their Roman numerals. Effects of intensified management of hay-meadows on population dynamics of Succisa pratensis. Manuscript. Intensified management affects population growth differently in the two perennial herbs Hypochoeris maculata and Polygala amarella. Manuscript. Artificial dispersal as...
Improper forest harvesting can potentially degrade forest ecosystem functions and services. Human-assisted regeneration (e.g., planting) is often used to increase the rate of forest recovery and thereby reduce regeneration failure. Seed dispersal is a fundamental ecological process that can also influence spatio-temporal patterns of forest regeneration. In this study, we investigated the relati...
