Ecological-economic optimization of biodiversity conservation under climate change

Substantial investment in climate change research has led to dire predictions of the impacts and risks to biodiversity. The Intergovernmental Panel on Climate Change fourth assessment report(1) cites 28,586 studies demonstrating significant biological changes in terrestrial systems(2). Already high extinction rates, driven primarily by habitat loss, are predicted to increase under climate change(3-6). Yet there is little specific advice or precedent in the literature to guide climate adaptation investment for conserving biodiversity within realistic economic constraints(7). Here we present a systematic ecological and economic analysis of a climate adaptation problem in one of the world's most species-rich and threatened ecosystems: the South African fynbos. We discover a counterintuitive optimal investment strategy that switches twice between options as the available adaptation budget increases. We demonstrate that optimal investment is nonlinearly dependent on available resources, making the choice of how much to invest as important as determining where to invest and what actions to take. Our study emphasizes the importance of a sound analytical framework for prioritizing adaptation investments(4). Integrating ecological predictions in an economic decision framework will help support complex choices between adaptation options under severe uncertainty. Our prioritization method can be applied at any scale to minimize species loss and to evaluate the robustness of decisions to uncertainty about key assumptions.

Pieces of Iowa’s Past, March 28, 2012

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. THIS WEEK: Electric Lighting in the Iowa State Capitol BACKGROUND: REPORT OF COMMITTEE ON LIGHTING THE BUILDING AND GROUNDS WITH ELECTRICITY—1882 The Capitol Commissioners submitted biennial reports throughout the 15 years it took to build the Capitol (1871-1886). Often there were committees formed to investigate a certain phase of the construction. The following is the report of the Committee on Lighting. Note: The Capitol Commissioners determined the gas lighting to be the best choice in the 1880s. Less than 20 years later, the process began to convert the Capitol from gas to electric lighting. There was a period where both types of lighting were being used in the Capitol. The photograph of the 1904 apple harvest shows both electric and gas fixtures. The turn of the 20th century photograph of the library also shows chandeliers utilizing both gas and electricity. The photograph of the single fixture in the library is a mystery. It shows a fixture utilizing both gas and electricity, but no other photographs of the library exist where this fixture appears. Perhaps it was a prototype and never used in the Capitol.

Deu anys de seguiment demogràfic i genètic d"Stachys maritima a Catalunya (2001-2010). Implicacions per a un pla de recuperació.

Ten years of demographic and genetic monitoring of Stachys maritima in Catalonia (2001-2010). Implications for a recovery plan.- Stachys maritima is a species typical of the coastal dunes, with a wide distribution within the Mediterranean Basin. In spite of this, the species shows a clear regression. In Catalonia, it has been observed an important reduction of its populations since early 20th century, where it has disappeared from several localities in which it was relatively common (Tarragonès, Barcelonès). Herein we present the results of the demographic monitoring of the species during the last 10 years (2001-2010) in the known localities in Catalonia. Besides corroborating the disappearance (northern Sant Martí d'Empúries), the re-discovering (Llobregat Delta beach) and the detection of new populations (inner dunes of the Montgrí), a large year-to-year fluctuation of the monitored populations is stated; the possible reasons are discussed. In addition, the present work also includes the results of the allozyme diversity analysis of the new detected populations as well as the rediscoveries of the period 2004-2008, which were not included in a former study of genetic diversity carried out in 2002-2003. It is necessary to emphasize that the contribution of the new populations to the genetic diversity of Stachys maritima is very small, which can be attributed to their limited population size and /or to founder effects. Despite that the species is included in the Annex 2 ('En Perill d'Extinció') within the Catàleg de Flora Amenaçada de Catalunya (Catalogue of Endangered Flora of Catalonia), and some 'soft' conservation measures have been applied at local level (signposting of the beach accesses, environmental education, etc.) coupled with other more significant measures (e.g. translocation of individuals discovered in an artificial sandbank), it would be necessary the coordinated action and the scientific support of any initiative of conservation that could be carried out. The general frame to initiate actions of conservation should be the recovery plan of Stachys maritima, whose draft and application is mandatory in accordance to the Catàleg.

Algunos tipos de cistáceas béticas y rifeñas de los herbarios BC, MA y MAF.

We indicate nomenclatural types (lectotypes and isolectotypes) for 10 taxa of the genus Cistus, Halimium and Helianthemum described from Andalusia and northern Morocco by botanists of the first half of the 20th century such as Font Quer, Pau, Cuatrecasas and Sennen. These types are conserved in the Spanish herbaria mentioned above, and some of them belong to the exsiccatae"Iter maroccanum" and"Plantes d"Espagne". Keywords: Nomenclatural types, Cistaceae, Andalusia, northern Morocco.

Analytical progresses of the International Olympic Committee and World Anti-Doping Agency Olympic laboratories.

The Summer Olympic Games constitute the biggest concentration of human sports and activities in a particular place and time since 776 BCE, when the written history of the Olympic Games in Olympia began. Summer and Winter Olympic anti-doping laboratories, accredited by the International Olympic Committee in the past and the World Anti-Doping Agency in the present times, acquire worldwide interest to apply all new analytical advancements in the fight against doping in sports, hoping that this major human event will not become dirty by association with this negative phenomenon. This article summarizes the new analytical progresses, technologies and knowledge used by the Olympic laboratories, which for the vast majority of them are, eventually, incorporated into routine anti-doping analysis.

Chirurgie endoscopique endonasale des tumeurs de la base du crane : historique, état de l'art et perspectives d'avenir [Shifting paradigm in skull base surgery: Roots, current state of the art and future trends of endonasal endoscopic approaches].

During the last two decades, endoscopic endonasal approach has completed the minimally invasive skull base surgery armamentarium. Endoscopic endonasal skull base surgery (EESBS) was initially developed in the field of pituitary adenomas, and gained an increasing place for the treatment of a wide variety of skull base pathologies, extending on the midline from crista galli process to the occipitocervical junction and laterally to the parasellar areas and petroclival apex. Until now, most studies are retrospective and lack sufficient methodological quality to confirm whether the endoscopic endonasal pituitary surgery has better results than the microsurgical trans-sphenoidal classical approach. The impressions of the expert teams show a trend toward better results for some pituitary adenomas with the endoscopic endonasal route, in terms of gross total resection rate and probably more comfortable postoperative course for the patient. Excepting intra- and suprasellar pituitary adenomas, EESBS seems useful for selected lesions extending onto the cavernous sinus and Meckel's cave but also for clival pathologies. Nevertheless, this infatuation toward endoscopic endonasal approaches has to be balanced with the critical issue of cerebrospinal fluid leaks, which constitutes actually the main limit of this approach. Through their experience and a review of the literature, the authors aim to present the state of the art of this approach as well as its limits.

Addressing non-communicable diseases in the Seychelles: towards a comprehensive plan of action.

This article reviews the different steps taken during the past 20 years for the prevention and control of non-communicable diseases (NCDs) in the Seychelles. National surveys revealed high levels of several cardiovascular risk factors and prompted an organized response, starting with the creation of an NCD unit in the Ministry of Health. Information campaigns and nationwide activities raised awareness and rallied increasingly broad and high-level support. Significant policy was developed including comprehensive tobacco legislation and a School Nutrition Policy that bans soft drinks in schools. NCD guidelines were developed and specialized 'NCD nurses' were trained to complement doctors in district health centers. Decreasing smoking prevalence is evidence of success, but the raising so-called diabesity epidemic calls for an integrated multi-sector policy to mould an environment conducive to healthy behaviors. Essential components of these efforts include: effective surveillance mechanisms supplemented by focused research; generating broad interest and consensus; mobilizing leadership and commitment at all levels; involving local and international expertise; building on existing efforts; and seeking integrated, multi-disciplinary and multi-sector approaches.

The Glass Floor.

A photographic and video record of the project to recreate and reconstruct the glass floor for the opening between the ground and first floors in the rotunda of the Iowa State Capitol. The original glass floor was removed in the early 20th century, but the decision was made to put a new one in to help improve the acoustics and air flow in the building.

The Biblioteca de Catalunya: working for the present and the future

The Biblioteca de Catalunya (BC) was created in 1907 by the Institut d’Estudis Catalans (IEC). In 1914 the Mancomunitat de Catalunya gave the library its condition of cultural and public service, open to researchers and scholars. The library underwent several changes as a consequence of political events, along the most of 20th century. In 1981 it was recognized by law as national library and it recovered its foundational aim of gathering, preserving and disseminating the bibliographical output of Catalonia and the production related with the Catalan linguistic field. As the proud host of ANADP2, the BC wants to show the attendees to the conference how, since 2004, has positioned itself to face the challenge of the new informational and technological paradigm. The library strategy for oncoming years includes giving open and free access online to the digitization of many of his collections through the portals MDC (Digital Memory of Catalonia), ARCA (Old Catalan Serials Archive) and Google Books project; the creation of the Web Archive of Catalonia and, as the last step in the consolidation of its policy, a high-security preserving repository named COFRE, based on the international guidelines and initiatives and the experience of the BC itself.
