Environmental Impacts on the Population Dynamics of a Tropical Seabird in the Context of Climate Change: Improving Inference through Hierarchical Modeling
(2008-04-25)Under the increasing threat of climate change, it is imperative to understand the impact that environmental phenomena have on the demography and behavior of natural populations. In the last few decades an ever increasing ... -
Favorable Climate Change Response Explains Non-Native Species' Success in Thoreau's Woods
(2010)Invasive species have tremendous detrimental ecological and economic impacts. Climate change may exacerbate species invasions across communities if non-native species are better able to respond to climate changes than native ... -
Phenological Shifts in Loggerhead Sea Turlte Nesting Dates
(2010-04-29)In 2007, the newest report of the Intergovernmental Panel on Climate Change (IPPC) stated that warming of the global climate system is now occurring at an unprecedented rate. Scientists have observed significant temperature ... -
Phenology and Fate of Palm Fruits of two canopy palms:Welfia regia and Euterpe precatoria
(2008-04-25)The CICLOS project, located at La Selva Biogical Research Station in Costa Rica, attempts to document the effects of ENSO on tree growth and builds upon past studies at La Selva, integrating studies of stand dynamics, forest ... -
Quantifying Ecologically Significant Feeding Areas for Marine Mammals and Seabirds in the Arctic
(2017-04-27)The Arctic marine ecosystem is highly dynamic and sensitive to environmental change, experiencing the impacts of climate change at a rate at least twice as fast as other areas of the world. Arctic organisms are adapted to ... -
The Causes and Fitness Benefits of Germinating Later in the Presence of Neighbors
(2018)Theoretical and empirical studies have consistently shown that the optimal timing of seed germination reduces exposure to physical stress and minimizes competitive interactions with neighbors. However, this research has ... -
The Effect of Warming on Phenology, Physiology, and Leaf Nitrogen in Six Deciduous Tree Species Over the Growing Season
(2013)There is no consensus on climatic warming's effect on phenology, photosynthesis, and leaf nitrogen content in temperate deciduous tree species. A major question is whether or how these trees will utilize a longer growing ... -
The Influence of Genetic and Environmental Factors on the Phenology and Life-Cycle Expression of Arabidopsis thaliana
(2015)This dissertation examines the processes that generate phenotypic variation in life cycles in seasonal environments. Collectively, a life cycle describes the stages an organism passes through during a generation. The timing, ... -
The Roles of Phenotypic Plasticity and Plant-Microbe Interactions in the Evolution of Complex Traits in Boechera stricta
(2016)All organisms live in complex habitats that shape the course of their evolution by altering the phenotype expressed by a given genotype (a phenomenon known as phenotypic plasticity) and simultaneously by determining the ...
