چکیده
Date: August 29 Place: Room 5336 (oral) Organizer: Lynn Anderson-Carpenter Contact email address: [email protected] Purpose: The merging of disparate scientific fields can provide the most exciting and challenging aspects of research. The combination can often give new results and solve long-standing questions that neither field could address alone. For example, the combination of ancient DNA and palynology can provide taxonomic identification for morphologically similar species. Differentiating these species can often give a finer-scale resolution of shifting geographic ranges. Additional investigation can elucidate genetic change over time and give insight to implications for organismal response to shifting climates. This research is not without its challenges, and the technical implications must be addressed in parallel with this new data. For example contamination is a constant problem, particularly as DNA concentration tends to decrease with increasing sample age. The purpose of this session is to bring together ancient DNA with the fields of palynology, paleoecology and phylogenetics. We will address a wide variety of topics including the combination of contemporary genetic patterns with paleoecological data, a DNA analysis of pollen and sediments, ice core genetics, and the combination of paleobotanical models with contemporary genetic data. Such mergers are well suited to tackle a variety of questions that are certain to provide an entertaining and informative discussion.

Introduction & Objective: Knowledge transfer and in fact, the bridging of theory and practice is one of the main concerns of all academic disciplines. Getting prominent professional status is the thing that can be achieved by knowledge-based function, and of which would be called as successful discipline that it be able to transfer its theoretical paradigmatic claims into practice. Accordingly,...
متن کاملMarine palynology and its use for studying nearshore environments
Palynology is the study of microfossils composed of highly resistant organic matter called palynomorphs. In the sediments of neritic environments, palynomorphs may include cysts of dinoflagellates, phycoma of prasinophytes, organic linings of benthic foraminifers and thecamoebians, in addition to inputs from the terrestrial vegetation (pollen grains and spores) or the freshwater biota (chloroco...
متن کاملBridging the Gap Between Research and Policy and Practice; Comment on “CIHR Health System Impact Fellows: Reflections on ‘Driving Change’ Within the Health System”
Far too often, there is a gap between research and policy and practice. Too much research is undertaken with little relevance to real life problems or its reported in ways that are obscure and impenetrable. At the same time, many policies are developed and implemented but are untouched by, or even contrary to evidence. An accompanying paper describes an innovative progr...
