Acclimation And Migration Potential Of A Boreal Forest Tree, Balsam Poplar (Populus Balsamifera L.) In A Changing Climate, Amanda L. Robertson

Biological Sciences

In the North American boreal forest, 21st century climate change is projected to result in longer growing seasons, increased forest productivity, and northward expansions or shifts in species ranges. These projected impacts are largely based on observations across natural temperature gradients, e.g., latitude or altitude, or correlations between current species' distributions and modern climate envelopes. These approaches, although valuable, do not consider biological capacities important in a species' ability to cope with novel environments through physiological or phenological acclimation. Within a single species, adaptation to local environments may cause some populations to respond differently to climate change than others. Acclimation …

Demographic Limits Of Nineteenth-Century Mormon Polygyny, Val Lambson, Davis Bitton

BYU Studies

What percentage of nineteenth-century Mormons practiced polygyny? Estimates of the answer have evolved as have the methods of posing the question. The authors use a simple demographic model to derive mathematical limits on polygyny prevalence. These limits provide benchmarks from which to assess whether polygyny prevalence in a given context is high or low compared to what is sustainable. If prevalence is high, the model may suggest where to look for reasons. Furthermore, where data are of low quality, the benchmarks provide a check on the reliability of the reported prevalence.

Many factors—such as differences in marriageable age, mortality, population …

Human Disturbance And Birds Of The Northeast: What Makes Some Species Decline, While Others Are Just Fine?, Leone Marion Brown

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Mounting evidence reveals the negative impacts of human activities on wildlife populations. However, studies investigating species' responses to human disturbance often rely on patterns of species' richness or abundance, and may not reflect underlying demographic processes. Is there evidence across geographic regions that humans are causing marked changes in species' survival, reproduction, and population growth? Do species' traits influence vulnerability? Can existing theories of ecology serve to predict or explain observable responses to human disturbance? I examined evidence of effects of human disturbance on populations of 24 breeding bird species across the northeastern United States. Based on reported literature and …

Cataloguers are the specialists responsible for bibliographic control, information management and the creation of resource discovery tool that aids user in their search for materials. Essentially, they are responsible for the provision and organisation of efficient and effective retrieval system. Thereby saves time, increases the quality/productivity of library users and ultimately enhances the performance of the institution to achieve set objectives. Literatures indicated swift changes in duties, skills and functions of cataloguers. The changes had posed …

Metabolic Syndrome And Migraine., Amit Sachdev, Michael J Marmura

Department of Jefferson Headache Center Papers and Presentations

Migraine and metabolic syndrome are highly prevalent and costly conditions. The two conditions coexist, but it is unclear what relationship may exist between the two processes. Metabolic syndrome involves a number of findings, including insulin resistance, systemic hypertension, obesity, a proinflammatory state, and a prothrombotic state. Only one study addresses migraine in metabolic syndrome, finding significant differences in the presentation of metabolic syndrome in migraineurs. However, controversy exists regarding the contribution of each individual risk factor to migraine pathogenesis and prevalence. It is unclear what treatment implications, if any, exist as a result of the concomitant diagnosis of migraine and …

We will continue to work with them to advocate for our collections budget. As we explore these issues for our campus, larger questions come up. Which data best promotes libraries? What are additional strategies to pique …

Impacts Of Climate Variability And Human Colonization On The Vegetation Of The Gala´Pagos Islands, Alejandra Restrepo, Paul A. Colinvaux, Mark B. Bush, Alexander Correa-Metrio, Jessica L. Conroy, Mark R. Gardener, Patricia Jaramillo, Miriam Steinitz-Kannan, Jonathan T. Overpeck

Biomedical Engineering and Sciences Faculty Publications

A high-resolution (2-9 year sampling interval) fossil pollen record from the Galapagos Islands, which spans the last 2690 years, reveals considerable ecosystem stability. Vegetation changes associated with independently derived histories of El Niño Southern Oscillation variability provided evidence of shifts in the relative abundance of individual species rather than immigration or extinction. Droughts associated with the Medieval Climate Anomaly induced rapid ecological change that was followed by a reversion to the previous state. The paleoecological data suggested nonneutral responses to climatic forcing in this ecosystem prior to the period of human influence. Human impacts on the islands are evident in …

Diet And Affinity From The Middle Neolithic To Early Bronze Age, Estremadura, Portugal: A Comparison Of Human Dental Remains From Feteira Ii And Bolores, Briana Christa Horwath

Anthropology

The social and political changes accompanying the transition from the Neolithic through Early Bronze Age in southwestern Iberia are reasonably well understood; much less is known about population movements and dietary changes that accompanied these transformations. To address possible population movements and dietary change, human dental remains from the Middle Neolithic through Late Neolithic site of Feteira II (3600-2900 B.C.E) and the Late Neolithic through the Early Bronze Age site of Bolores (2800-1800 B.C.E) will be used to examine diet and affinity. Two hypotheses are tested: the period of social change was associated with dietary change between individuals interred at …

Factors Affecting Survival Of Arctic-Breeding Dunlin (Calidris Alpina Arcticola) Adults And Chicks, Brooke Lynne Hill

Biological Sciences

Accurate estimates of, and identifying factors affecting, survival and productivity can provide insight into population trends and help determine what management actions would most benefit a population. Only limited demographic data are available for many Arctic-breeding shorebird species. I estimated survival probabilities for Arctic-breeding Dunlin (Calidris alpina arcticola); for adults between 2003 and 2010, and for chicks in 2008 and 2009. Adult apparent survival probabilities were higher for males (0.60 ± 0.04) than females (0.41 ± 0.05), were higher for individuals initiating nests earlier in the season, and yearly variation was high. These apparent survival rates appear insufficient to maintain …

The Perceived Value Of Videogame Packaging Among Young Adults, Colby Kibbe

Theses

Numerous forms of media content that once utilized physical distribution, such as music, movies, and publications, are now being distributed digitally. Videogames are the latest media content to be distributed in this manner, thus removing suppliers--such as packaging printers--who played a role in traditional physical distribution. With the U.S. printing industry projected to decline by 15% by 2015 (Romano & Broudy, 2010), the loss of packaged videogames as a source of revenue for packaging printers may further threaten the viability of the industry. The purpose of this research was to determine the current perceived value of packaged vs. digitally distributed …
