Elife, 6, 8. doi:10.7554/eLife.24611Many discoveries in the life sciences have been made using material from living stock collections. These collections provide a uniform and stable supply of living organisms and related materials that enhance the reproducibility of research and minimize the need for repetitive calibration. While collections differ in many ways, they all require expertise in maintaining living organisms and good logistical systems for keeping track of stocks and fulfilling requests for specimens. Here, we review some of the contributions made by living stock collections to research across all branches of the tree of life, and outline the challenges they face

An evaluation of the status of living collections for plant, environmental, and microbial research

Journal of Biosciences, 42(2), 321-331. https://doi.org/10.1007/s12038-017-9685-6While living collections are critical for biological research, support for these foundational infrastructure elements is inconsistent, which makes quality control, regulatory compliance, and reproducibility difficult. In recent years, the Ecological Society of America has hosted several National Science Foundation–sponsored workshops to explore and enhance the sustainability of biological research infrastructure. At the same time, the United States Culture Collection Network has brought together managers of living collections to foster collaboration and information exchange within a specific living collections community. To assess the sustainability of collections, a survey was distributed to collection scientists whose responses provide a benchmark for evaluating the resiliency of these collections. Among the key observations were that plant collections have larger staffing requirements and that living microbe collections were the most vulnerable to retirements or other disruptions. Many higher plant and vertebrate collections have institutional support and several have endowments. Other collections depend on competitive grant support in an era of intense competition for these resources. Opportunities for synergy among living collections depend upon complementing the natural strong engagement with the research communities that depend on these collections with enhanced information sharing, communication, and collective action to keep them sustainable for the future. External efforts by funding agencies and publishers could reinforce the advantages of having professional management of research resources across every discipline. © 2017 Indian Academy of Science

Interview with Albert S. Peeling, June 3, 1995

Albert S. Peeling was interviewed on June 3, 1995 by Michael J. Birkner & David Hedrick about his years as a student at Gettysburg College in the class of 1925. Peeling discusses his memories of the faculty as a history major and life at the college at the time, such as living quarters and athletics.

The Mechanics and Statistics of Active Matter

Active particles contain internal degrees of freedom with the ability to take in and dissipate energy and, in the process, execute systematic movement. Examples include all living organisms and their motile constituents such as molecular motors. This article reviews recent progress in applying the principles of nonequilibrium statistical mechanics and hydrodynamics to form a systematic theory of the behaviour of collections of active particles -- active matter -- with only minimal regard to microscopic details. A unified view of the many kinds of active matter is presented, encompassing not only living systems but inanimate analogues. Theory and experiment are discussed side by side.Comment: This review is to appear in volume 1 of the Annual Review of Condensed Matter Physics in July 2010 and is posted here with permission from that journa

[Review of] Gary Soto. Baseball in April and Other Stories

Gary Soto\u27s previous prose collections (Living Up the Street: Narrative Recollections -- 1985, Small Faces -- 1986, and Lesser Evils: Ten Quartets -- 1988) all contained stories about growing up, but this latest book focuses exclusively on the trials and tribulations of children and young teenagers. The eleven sketches in Baseball in April range in subject from broken Barbie dolls to championship marble tournaments, and all reveal a compassionate, understanding insight as well as the deft handiwork of a fine writer. For those who do not understand Spanish, the author has supplied a short appendix with translations of words and expressions. Artist Barry Root\u27s dust jacket depicting a red pickup full of boys and baseball gear is a splendid one that invites the reader to delve into the volume

Conservation of threatened relict trees through living ex situ collections: lessons from the global survey of the genus Zelkova (Ulmaceae)

Maintaining living ex situ collections is one of the key conservation methods in botanic gardens worldwide. Despite of the existence of many other conservation approaches used nowadays, it offers for many endangered plants an important insurance policy for the future, especially for rare and threatened relict trees. The aim of this research was to investigate the global extent of living ex situ collections, to assess and discuss their viability and inform the development of conservation approaches that respond to latest global conservation challenges. We used as a model taxon the tree genus Zelkova (Ulmaceae). The genus includes six prominent Tertiary relict trees which survived the last glaciation in disjunct and isolated refugial regions. Our comprehensive worldwide survey shows that the majority of botanic institutions with Zelkova collections are in countries with a strong horticultural tradition and not in locations of their origin. More importantly, the acutely threatened Zelkova species are not the most represented in collections, and thus safeguarded through ex situ conservation. Less than 20% of the ex situ collections surveyed contain plant material of known wild provenance while the majority (90%) of collections are generally very small (1-10 trees). Botanic gardens and arboreta particularly in regions where iconic relict trees naturally occur should play a vital role in the conservation of these species. The coordination of conservation efforts between gardens has to be enhanced to prioritise action for the most threatened relict trees. Large scale genetic studies should be undertaken, ideally at genus level, in order to verify or clarify the provenance of ex situ collections of relict trees in cultivation. For the most threatened relict tree genera, well-coordinated specialist groups should be create

Caddo Ceramics from an Early 18th Century Spanish Mission in East Texas: Mission San Jose de los Nasonis (41RK200)

Mission San Jose de los Nasonis (4JRK200) and two contemporaneous Nasoni Caddo sites (41RK191 and 41RK197) were located by Mr. Bill Young more than 25 years ago in the southern part of Rusk County, Texas after the general area of the site had been cleared of timber. The mission site covers ca. 6.6 acres of an upland ridge along a small tributary to the Angelina River; the ridge projects into the Angelina River floodplain. The topographic setting of Mission San Jose conforms in all particulars to the settings of other known mission sites established among the Caddo: small hills adjacent to a floodplain, next to a stream, with the hills lower extensions of more extensive upland areas. Corbin also notes that these missions were located within the area of the local dispersed Caddoan village, none of the locations are places suited to support the Indian-based community that the Spanish hoped to entice to the location. This mission was established as one of six different missions by the Spanish in 1716 during their second attempt (the first being in 1690-1691) to establish a religious and political presence among the Caddo peoples in East Texas, specifically to minister to the Nasoni Caddo living in the area. Mission San Jose de los Nasonis ·was formally established on July 10, 1716. Father Espinosa and Captain Don Domingo Ramon, the leader of the expedition, had noted that there were many Hasinai Caddo ranchos in the general area along with arroyos of water and good places for settlement. Both Nasoni and Nacono Caddo were then living in this area of the Angelina river. Mr. Young made those collections available for study in 2006, and this article is a summary of the Caddo ceramics in the Mission Nasonis collections. In 1990, Dr. James E. Corbin of Stephen F. Austin State University (SFASU) and Dr. Kathleen Gilmore of the University of North Texas conducted limited excavations in Area A at the mission site, but these excavations have never been published. More than 930 Caddo ceramic sherds were recovered in that work, and are curated at SFASU; the separate analysis of these ceramic artifacts is underway
