A Story Of Data Won, Data Lost And Data Re-Found: The Realities Of Ecological Data Preservation, Alison Specht

DataONE Sociocultural and Usability & Assessment Working Groups

This paper discusses the process of retrieval and updating legacy data to allow on-line discovery and delivery. There are many pitfalls of institutional and non-institutional ecological data conservation over the long term. Interruptions to custodianship, old media, lost knowledge and the continuous evolution of species names makes resurrection of old data challenging. We caution against technological arrogance and emphasise the importance of international standards.

We use a case study of a compiled set of continent-wide vegetation survey data for which, although the analyses had been published, the raw data had not. In the original study, publications containing plot data collected …

Initial Limnological Observations At Five Small Lakes In Southern Pacific Costa Rica, Sally P Horn, Erik N. Johanson, Kurt A. Haberyan, Mathew S. Boehm, Jessie L. Johanson, Maureen Sánchez P., Mario Hernández V.

Geography Publications and Other Works

Costa Rica has hundreds of lakes, many of which have never been described or sampled by limnologists. Here we summarize initial observations of five small (0.2–1.7ha) lakes located at low elevation (365–490m) in the cantón of Buenos Aries. We collected basic limnological data and samples during visits in 2013 and 2014, and compiled environmental and archaeological data for their surroundings as a contribution to the documentation of lake diversity in Costa Rica, and to support parallel investigations of indicators of environmental history preserved in the sediments of the lakes. Lagunas Carse, Los Mangos, Danta, and Ojo de Agua all appear …

In this report and accompanying high-resolution images we make available photographs of stem cross sections, plants, and habitats of H. irazuense in support of a recent study of the dendrochronological potential of the species (Kerr et al., forthcoming paper in Physical Geography) and other research on this plant and the páramo vegetation in which it occurs. We also include images from the Google Earth^TM map …

Fire History Of The Appalachian Region: A Review And Synthesis, Charles W. Lafon, Adam T. Naito, Henri D. Grissino-Mayer, Sally P Horn, Thomas A. Waldrop

Geography Publications and Other Works

The importance of fire in shaping Appalachian vegetation has become increasingly apparent over the last 25 years. This period has seen declines in oak (Quercus) and pine (Pinus) forests and other fire-dependent ecosystems, which in the near-exclusion of fire are being replaced by fire-sensitive mesophytic vegetation. These vegetation changes imply that Appalachian vegetation had developed under a history of burning before the fire-exclusion era, a possibility that has motivated investigations of Appalachian fire history using proxy evidence. Here we synthesize those investigations to obtain an up-to-date portrayal of Appalachian fire history. We organize the report by …

Fire in Highland Pine Forests of the Dominican Republic―The Long View

Large forest fires in Valle Nuevo National Park in 2014 and 2015 have increased interest in fire as an ecological force in montane pine forests of the Dominican Republic. Geographer Dr. José Ramón Martínez Batlle estimated using Landsat imagery and GIS that some 4700 ha burned in July 2014 (http://www.geografiafisica.org/2014/07/29/superficie-quemada-incendio-valle-nuevo/), and an additional 1600 ha burned in late April 2015 (http://www.geografiafisica.org/2015/09/25/superficie-quemada-en-valle-nuevo-finales-de-abril-principios-de-mayo-2015/).

Since 1995, when I first visited what is today Valle Nuevo National Park (then, Valle Nuevo Scientific Reserve), as a guest of the Moscoso …

Convergence To Consensus In Heterogeneous Groups And The Emergence Of Informal Leadership, Sergey Gavrilets, Jeremy David Auerbach, Mark Van Vugt

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

When group cohesion is essential, groups must have efficient strategies in place for consensus decisionmaking. Recent theoretical work suggests that shared decision-making is often the most efficient way for dealing with both information uncertainty and individual variation in preferences. However, some animal and most human groups make collective decisions through particular individuals, leaders, that have a disproportionate influence on group decision-making. To address this discrepancy between theory and data, we study a simple, but general, model that explicitly focuses on the dynamics of consensus building in groups composed by individuals who are heterogeneous in preferences, certain personality traits (agreeability and …

Social Network And Content Analysis Of The North American Carbon Program As A Scientific Community Of Practice, Molly E. Brown, Monica Inez Ihli, Oscar Hendrick, Sabrina Delgado-Arias, Vanessa M. Escobar, Peter Griffith

UT Libraries Faculty: Peer-Reviewed Publications

The North American Carbon Program (NACP) was formed to further the scientific understanding of sources, sinks, and stocks of carbon in Earth's environment. Carbon cycle science integrates multidisciplinary research, providing decision-support information for managing climate and carbon-related change across multiple sectors of society. This investigation uses the conceptual framework of communities of practice (CoP) to explore the role that the NACP has played in connecting researchers into a carbon cycle knowledge network, and in enabling them to conduct physical science that includes ideas from social science. A CoP describes the communities formed when people consistently engage in shared communication and …

Toward A New Understanding Of Virtual Research Collaborations: Complex Adaptive Systems Framework, Arsev U. Aydinoglu

DataONE Sociocultural and Usability & Assessment Working Groups

Virtual research collaborations (VRCs) have become an important method of conducting scientific activity; however, they are often regarded and treated as traditional scientific collaborations. Their success is measured by scholarly productivity and adherence to budget by funding agencies, participating scientists, and scholars. VRCs operate in complex environments interacting with other complex systems. A holistic (or organicist) approach is needed to make sense of this complexity. For that purpose, this study proposes using a new perspective, namely, the complex adaptive systems theory that can provide a better understanding of a VRC’s potential creativity, adaptability, resilience, and probable success. The key concepts …

DataONE Sociocultural and Usability & Assessment Working Groups

In response to the increasing need for a data curation workforce, the Data Curation Education in Research Centers program is educating library and information science students in scientific data curation. During the summer of 2012, the authors worked alongside scientists and data managers at the National Center for Atmospheric Research in Boulder, Colorado, to learn data curation within the context of a research center. Each student was matched with a “Science Mentor” and a “Data Mentor” based on prior work experience and the results of a placement questionnaire completed before the internship. Though NCAR has robust data services, we found …

Faculty Publications and Other Works -- EECS

This brief article explores the current state of library and information science (LIS) programs in terms of their nature and composition in state universities in India. Preliminary findings were based on a content analysis of representative information regarding LIS education available on the websites of all state universities and colleges that offer LIS programs in India. Findings indicated broad trends in administrative structuring and nomenclature of LIS programs which requires standardization. The type of degrees awarded, the composition of faculty positions, student places per year and student-faculty ratios was also found to be varied among the different institutions. The lack …

Understanding The Data Management Needs And Data Sharing Challenges Of Environmental Scientists, Carol Tenopir, Suzie Allard, Miriam L.E. Steiner Davis

DataONE Sociocultural and Usability & Assessment Working Groups

Surveys of scientists for the NSF DataONE project and the USGS Southeast Information Node of the National Biological Information Infrastructure (NBII), as well as follow-up interviews, show that environmental scientists are interested in sharing their data with certain conditions, such as citations or acknowledgment. Government scientists are more likely to be satisfied with the processes for data management than are academic scientists, but less likely to be satisfied with the process of describing data or tools for documentation. Both groups value trusted and complete sources. There are many ways that scientists can be assisted with data management throughout the data …

Folksonomy-Based User-Centric Information Organization Systems, Devendra Potnis

School of Information Sciences -- Faculty Publications and Other Works

After the rise of Web 2.0 technologies, Folksonomy emerged as one of the most popular user-centric information organization techniques in the newly reforming digital world. ln the context of the rising popularity of folksonomies, this paper conceptually investigates -- how can folksonomies be integrated with other ways of organizing information for building systems that could serve information users better in the future? A set of experimentation ideas of integrating folksonomy with controlled vocabularies, bibliometric maps, thesaurus-based systems, ontologies, and semantic web could inform and catalyze the design and development of folksonomy-based user-centric information organization systems in the future.

Limnología De Las Lagunas Glaciales En El Páramo Del Chirripó, Costa Rica. (Limnology Of Glacial Lakes In The Chirripó Páramo Of Costa Rica.), Sally P Horn, Kenneth H. Orvis, Kurt A. Haberyan

Geography Publications and Other Works

More than 30 lakes of glacial origin exist within the Chirripó páramo in the Cordillera de Talamanca of Costa Rica. This chapter describes the geomorphic setting and physical and chemical limnology of 19 lakes located between 3450-3570 m elevation in the upper basins of five glaciated valleys. All lakes are clear, dilute, and apparently polymictic. Water chemistry data from 1998, 2000, and 2001 are similar from lake to lake and year to year, and are consistent with sparse prior measurements between 1966 and 1991. However, the lake water temperatures we have measured are much higher than those reported by earlier …

Registros De Sedimentos Lacustres De La Vegetación Del Holoceno Y Historia Del Fuego En El Páramo De Costa Rica. (Lake-Sediment Records Of Holocene Vegetation And Fire History In The Costa Rican Páramos), Sally P Horn, Brandon L. League

Geography Publications and Other Works

We examined pollen, pteridophyte (ferns and fern-allies) spores, and charcoal in a 5.6 m long sediment core from Lago de las Morrenas 1, and charcoal in a 1.1 m long sediment core from Lago Chirripó, to reconstruct postglacial vegetation and fire history in the Chirripó páramo. Lago de las Morrenas 1, the largest lake in the Valle de las Morrenas of Chirripó National Park, is presently surrounded by treeless páramo vegetation and has apparently been so since deglaciation approximately 10,000 radiocarbon years ago. Pollen spectra suggest no pronounced changes in vegetation since ice retreat. Pollen percentages for Gramineae and other …
