Eco-evolutionary dynamics describe interactions between ecology and .. An emerging synthesis between community ecology and evolutionary biology. heritable relationship between plant genotype and associated soil. Ecology and Evolutionary Biology (EEB) at Princeton University is unique in its areas and often connect with faculty members between two or more areas. Some North American universities are home to degree programs titled Ecology and A program that focuses on the relationships and interactions that range across Among the best-known Ph.D.-granting departments that use this name are.

While this may be challenging for the reader, as a variety of questions and sub-fields of ecology and evolutionary theory will be briefly examined, I truly believe that what makes evolutionary ecology such a fascinating area of inquiry is its expansive reach.

Furthermore, one of the greatest open questions of organismal biology is precisely how the gap between ecological-population and evolutionary-species level phenomena is bridged. This question provides formidable challenges for both theoretical and empirical biologists and will likely see increasing attention and efforts over the next decades.

This chapter comprises several sections, ranging from the ecology and biogeography of Arabidopsis to the study of its quantitative genetics, from phenotypic plasticity to research conducted on other species comprising A. Why ecology and evolution of Arabidopsis?

Let us start by answering what might appear at first glance an odd question: The question is justified by the fact that the mouse ear cress A. For geneticists, the main reasons to focus on A.

Once that enough knowledge of the genetics and physiology of the plant had accumulated, it naturally became a favorite organism for molecular and then developmental biologists for similar reasons Dean ; Pyke ; Anderson and Roberts Ecologists and evolutionists have been much slower at capitalizing on the wealth of information available about the mouse-ear cress, despite some interesting early attempts that I will discuss in the next section. Having been on the receiving hand of general criticisms of the use of A.

Eco-evolutionary dynamics: intertwining ecological and evolutionary processes in contemporary time

There is a grain of truth in both these accusations. Evolutionarily, it probably constitutes a highly derived species with a somewhat unusual mating system. On the other hand, it is easy to push these objections beyond reason. As we shall see, the ecology of this cress is actually more interesting and varied than most people suspected, and annual selfers are by no means unusual beasts among flowering plants.

Furthermore, precisely the same objections can be raised to the other major model system in evolutionary biology: More importantly, after acknowledging the limitations intrinsic in the use of Arabidopsis as a tool for evolutionary ecology research, the advantages should not be underestimated. It is true that if plant ecologists and evolutionists had their pick of a model system they would probably focus on other organisms though no such species has in fact emerged throughout the 20th century.

Arabidopsis, maize, potato and Miscanthus are used in our research. Studies on computational aspects of alternative splicing and protein-protein interactions are being done in collaboration with Asa Ben-Hur in the Department of Computer Science at CSU http: I am co-director of the Bird Genoscape Project, a large, multi-institutional effort to use genomic methods to facilitate migratory bird conservation.

As part of this effort we are addressing questions such as: Molecular phylogenetics uses genomic data typically DNA sequences to reconstruct evolutionary relationships among species. This field is playing an increasingly central role in biology, from inferring the diversification of multigene families, to tracking invasive species, conservation of protected species, as evidence in criminal investigations, and fighting bioterrorism.

Dan Sloan - Assistant Professor Ph. University of Virginia My research investigates the evolutionary forces that create diversity in genome size, structure, and function. I am particularly interested in the evolution of so-called "resident genomes" that exist inside the cells of another organism, including those of mitochondria and plastids in eukaryotes and endosymbiotic bacteria in many insects.

Much of my current work focuses on how these resident genomes co-evolve with the host genome. Within this context, my research addresses questions about the functional roles of species in ecosystems, the causes and impacts of loss and gain of genetic and species diversity, the factors that influence species coexistence and patterns of species abundance, and the relative strength of bottom-up resources vs.

My research employs a mixture of empirical approaches observational, experimental, comparative and synthetic and utilizes C4-dominated grasslands as experimentally tractable and dynamic model systems.
