Clonal diversity in populations of Daphnia pulex reproducing by obligate parthenogenesis

Abstract: Allozyme studies of Daphnia pulex populations in southern Ontario revealed marked Hardy–Weinberg deviations, complete gametic phase imbalance, and high heterozygosity values. These genotypic characteristics reflect the loss of sexual reproduction; individuals reproduce by obligate parthenogenesis. Thirty-nine clones were identified in the twenty-one habitats surveyed; a few of these clones retained the ability to produce male offspring. Several clones were present in many habitats, but most of the thirty-nine clones were found in only a single pond. The large genetic distances between coexisting clones suggested that in situ mutational divergence was not the source of within habitat clonal diversity. Ecological differences between clones were suggested by distributional patterns and by temporal surveys of clone frequencies.

Designing Effective Marine Protected Areas in Seaflower Biosphere Reserve, Colombia, Based on Biological and Sociological Information

Abstract: : Ecologists have paid increasing attention to the design of marine protected areas (MPAs), and their design advice consistently recommends representing all habitat types within MPAs or MPA networks as a means to provide protection to all parts of the natural ocean system. Recent developments of new habitat-mapping techniques make this advice more achievable, but the success of such an approach depends largely on our ability to define habitat types in a way that is ecologically relevant. We devised and tested the ecological relevance of a set of habitat-type definitions through our participation in a stakeholder-driven process to design a network of MPAs, focusing on no-take marine reserves in the Seaflower Biosphere Reserve, San Andres Archipelago, Colombia. A priori definitions of habitat types were ecologically relevant, in that our habitat-type definitions corresponded to identifiable and unique characteristics in the ecological communities found there. The identification of ecological pathways and connectivity among habitats also helped in designing ecologically relevant reserve boundaries. Our findings contributed to the overall design process, along with our summary of other general principles of marine reserve design. Extensive stakeholder input provided information concerning the resources and their patterns of use. These inputs also contributed to the reserve design process. We anticipate success for the Seaflower Biosphere Reserve at achieving conservation and social goals because its zoning process includes detailed yet flexible scientific advice and the participation of stakeholders at every step. Resumen: Los ecologos han puesto mayor atencion en el diseno de areas marinas protegidas (AMP), y sus sugerencias de diseno recomiendan consistentemente la representacion de todos los tipos de habitat en los AMP o en las redes de AMP como una forma de proporcionar proteccion a todas las partes del sistema oceanico natural. Desarrollos recientes de tecnicas de mapeo de habitat nuevas hacen que estas recomendaciones sean mas realizables, pero el exito de esta metodologia depende, en buena medida, de nuestra capacidad de definir tipos de habitat de manera ecologicamente relevante. Participando en un proceso conducido por grupos de interes para disenar una red de AMPs, concentrada en reservas marinas sin extraccion en la Reserva de la Biosfera Seaflower, Archipelago San Andres, Colombia, disenamos y probamos la relevancia ecologica de un conjunto de definiciones de tipos de habitat. Las definiciones a priori de tipos de habitat fueron ecologicamente relevantes porque nuestras definiciones de tipos de habitat correspondieron a caracteristicas unicas e identificables de las comunidades ecologicas encontradas ahi. La identificacion de trayectorias ecologicas y la conectividad entre habitats tambien ayudaron al diseno de limites de reserva ecologicamente relevantes. Nuestros hallazgos contribuyeron al proceso de diseno en su conjunto, junto con nuestra recopilacion de otros principios generales para el diseno de reservas marinas. La participacion de los grupos de interes proporciono informacion concerniente a los recursos y sus patrones de uso. Esta participacion tambien contribuyo al proceso de diseno de la reserva. Anticipamos el exito para la Reserva de la Biosfera Seaflower en el cumplimiento de sus metas sociales y de conservacion porque en su proceso de zonificacion se incluyen recomendaciones cientificas detalladas pero flexibles y la participacion de grupos de interes en cada etapa.

Changeability – An Introduction

Abstract: Manufacturing has been experiencing dynamically changing environment that presents industrialists and academics with formidable challenges to adapt to these changes effectively and economically while maintaining a high level of responsiveness, agility and competitiveness. Advances in manufacturing technologies, equipment, systems and organizational strategies are helping manufacturers meet these challenges. The ability to change and effectively manage this change is a fundamental pre-requisite for surviving and prospering in this turbulent environment. Changeability is presented as an umbrella concept that encompasses many change enablers at various levels of an industrial company throughout the life cycle of the manufacturing system. In this introduction, the scope of manufacturing changeability is outlined, the objects of change are defined, the change enablers are introduced and discussed and the change management strategy is highlighted.

Predicting Performance Times From Deliberate Practice Hours for Triathletes and Swimmers: What, When, and Where Is Practice Important?.

Abstract: In Studies 1 and 2, the authors evaluated deliberate practice theory through analyses of the relationship between practice and performance for 2 populations of athletes: triathletes and swimmers, respectively. In Study 3, the authors obtained evaluations of practice from athletes' diaries. Across athletes, length of time involved in fitness activities was not related to performance. For the triathletes, a significant percentage of variance in performance was captured by practice. This was not so for sprint events for the swimmers, in which gender was a significant predictor. In the diaries, physical activities were perceived as enjoyable. In contrast to the results obtained from questionnaires, enjoyment did not covary with an activity's relevance to improving performance. Although these findings highlight the importance of sport-specific practice, the authors question a domain-independent account of expertise based on deliberate practice.
