So Long and Thanks for All the Sponge: Cryptic Intertidal Communities, Consequences of Ocean Acidification, and New Directions for Science Education

Creator:

Rickborn, Alissa J.

Abstract:

The current generation of scientists will be asked to mitigate climate change, stall biodiversity loss, and protect ecological communities. These are tasks that require a knowledge of both ecological and social systems to be undertaken successfully. Therefore, my dissertation spans the fields of community ecology and social sciences in an...

DISSERTATION OF Alissa J. Rickborn for the degree of Doctor of Philosophy in Zoology presented June 14
Stage-structured interactions and their consequences across levels of biological organization

Creator:

Segui, Leah Mupas

Abstract:

A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology assumes that individuals within a species are functionally identical and that consumer-resource dynamics can be predicted solely by using species abundances. However, one species can consist of multiple functional groups,...

Thermal Tolerance and Adaptation in Cnidarians: An Investigation of Host Transcriptomic Responses and Heritable Variation Across Natural Populations

Creator:

Dziedzic, Katherine E.

Abstract:

Coral reefs have become vulnerable to climate change, with mass bleaching events, the loss of symbiotic algae (Symbiodiniaceae), increasing in both frequency and severity. As climate change continues to threaten the persistence and existence of coral reefs around the world, the biggest question posed for coral reefs is “can they...

Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

Creator:

Coblentz, Kyle E.

Abstract:

Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:

Biel, Reuben G.

Abstract:

Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

An Integrated Approach to Gauge the Effects of Global Climate Change on Headwater Stream Ecosystems

Creator:

Bury, Gwendolynn W.

Abstract:

Climate change is predicted to affect ecosystems, including systems already stressed by human impacts. One ecosystem that is already highly impacted by human land use is the cold headwater stream system of the Pacific Northwest. One method of assessing the function of an ecosystem is by using an indicator species....

Predictability and constraints on the structure of ecological communities in the context of climate change

Creator:

Barner, Allison K.

Abstract:

Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...

Complexity in host-pathogen dynamics : dispersal uncertainties, metapopulation persistence and the role of a changing climate

Creator:

Xie, Yang

Abstract:

Emerging infectious diseases impact both human and wildlife populations. Infectious agents, in particular the aquatic fungus Batrachochytrium dendrobatidis (chytrid), have an influential role in driving global amphibian population declines. The emergence of the chytrid fungus has aspects of both geographic spread as well as climate shifts altering environmental conditions and...

The function of orange breeding coloration in the social behavior of the long-nosed leopard lizard (Gambelia wislizenii)

Creator:

Moore, Edith

Abstract:

The role of orange coloration in the breeding behavior of Gambelia wislizenii was examined in the Alvord Basin of southeast Oregon. Behavioral observations of free ranging lizards supplemented field experiments where I manipulated the sex and color of lizards encountered by resident female G. wislizenii before and after they acquired...

A comparative study of prenatal behavior ontogeny in altricial and precocial murid rodents

Creator:

Robinson, Scott R., 1952-

Abstract:

Using techniques that permit the direct observation of fetuses in vivo, prenatal behavioral development was compared among four species in the rodent family Muridae: the Norway rat (Rattus norvegicus), Mongolian gerbil (Meriones unguiculatus), cotton rat (Sigmodon hispidus), and spiny mouse (Acomys cahirinus). Rattus and Meriones bear altricial offspring, as do...
