An updated assessment of Symbiodinium spp. that associate with common scleractinian corals from Moorea (French Polynesia) reveals high diversity among background symbionts and a novel finding of clade B ArchiMer
Rouze, Heloise; Lecellier, Gael J.; Saulnier, Denis; Planes, Serge; Gueguen, Yannick; Wirshing, Herman H.; Berteaux-lecellier, Veronique.
The adaptative bleaching hypothesis (ABH) states that, depending on the symbiotic flexibility of coral hosts (i.e., the ability of corals to “switch” or “shuffle” their algal symbionts), coral bleaching can lead to a change in the composition of their associated Symbiodinium community and, thus, contribute to the coral’s overall survival. In order to determine the flexibility of corals, molecular tools are required to provide accurate species delineations and to detect low levels of coral-associated Symbiodinium. Here, we used highly sensitive quantitative (real-time) PCR (qPCR) technology to analyse five common coral species from Moorea (French Polynesia), previously screened using only traditional molecular methods, to assess the presence of...

Determinación del efecto de las importaciones en precios internos de granos básicos utilizando un sistema inverso de demanda Colegio de Postgraduados
Hernández Ortiz, Juan.
Con la entrada en vigor del TLCAN las importaciones de granos básicos en México han crecido sustancialmente, a raíz de este fenómeno mucho se ha comentado sobre la conveniencia o no del Tratado de Libre Comercio y sus efectos en la agricultura, derivados del crecimiento de las importaciones de dichos productos, sin embargo, no existen estudios donde se cuantifique la magnitud del impacto en la agricultura nacional. Por esta razón en este trabajo se aborda el efecto que tienen las importaciones de granos básicos en los precios internos de México, utilizando para ello un sistema inverso de demanda casi ideal; como resultado se obtienen flexibilidades menores que 1 en valor absoluto lo cual significa que los precios son inflexibles al cambio en...

Effect of frequency of static stretching on flexibility, hamstring tightness and electromyographic activity BJMBR
Marques,A.P.; Vasconcelos,A.A.P.; Cabral,C.M.N.; Sacco,I.C.N..
We compared the effect of the number of weekly repetitions of a static stretching program on the flexibility, hamstring tightness and electromyographic activity of the hamstring and of the triceps surae muscles. Thirty-one healthy subjects with hamstring tightness, defined as the inability to perform total knee extension, and shortened triceps surae, defined by a tibiotarsal angle wider than 90° during trunk flexion, were divided into three groups: G1 performed the stretching exercises once a week; G2, three times a week, and G3, five times a week. The parameters were determined before and after the stretching program. Flexibility improved in all groups after intervention, from 7.65 ± 10.38 to 3.67 ± 12.08 in G1, from 10.73 ± 12.07 to 0.77 ± 10.45 in G2,...

Forest Management Approaches for Coping with the Uncertainty of Climate Change: Trade-Offs in Service Provisioning and Adaptability Ecology and Society
Wagner, Sven; Chair of Silviculture, TU-Dresden; wagner@forst.tu-dresden.de; Nocentini, Susanna; Department of Agricultural, Food and Forestry Systems, University of Florence; susanna.nocentini@unifi.it; Huth, Franka; Chair of Silviculture, TU-Dresden; mario@forst.tu-dresden.de; Hoogstra-Klein, Marjanke; Forest and Nature Conservation Policy Group, Wageningen University; Marjanke.Hoogstra@wur.nl.
The issue of rapid change in environmental conditions under which ecosystem processes and human interventions will take place in the future is relatively new to forestry, whereas the provision of ecosystem services, e.g., timber or fresh water, is at the very heart of the original concept of forest management. Forest managers have developed ambitious deterministic approaches to provide the services demanded, and thus the use of deterministic approaches for adapting to climate change seem to be a logical continuation. However, as uncertainty about the intensity of climate change is high, forest managers need to answer this uncertainty conceptually. One may envision an indeterministic approach to cope with this uncertainty; but how the services will be...

Integrating Citizens in Adaptive Management: A Propositional Analysis Ecology and Society
Shindler, Bruce; Oregon State University; bruce.shindler@orst.edu; Aldred Cheek, Kristin; University of Montana; cheekK@forestry.umt.edu.
Lee has advocated for the use of civic science in the implementation of adaptive management experiments, noting that people and political processes are central features of adaptive approaches to land management. This paper explores the growing relationship between the public and forest management agencies, and uses a propositional analysis to guide methods for integrating citizens into adaptive management situations. Important characteristics are organized and discussed in six thematic areas. Citizen-agency interactions are more effective when (1) they are open and inclusive, (2) they are built on skilled leadership and interactive forums, (3) they include innovative and flexible methods, (4) involvement is early and continuous, (5) efforts result in...

Qualification of the adaptive capacities of livestock farming systems R. Bras. Zootec.
Dedieu,Benoît.
This paper aims at exploring what is covered by « adapting to last » with a farming systems approach. Long term dynamics can be analysed as adaptive cycles, the system being permanently exposed to disturbances and shocks. Mobilizing the concept of resilience, we analyse the factors that differentiate the principles for long term action the livestock farmers have, principles which give consistency to the family - farms trajectories. With the concept of operational flexibilty, we qualify the sources of flexibility the livestock farmers maintain to cope with hazards. They are internal, related to the production process regulation properties, to the technical (adaptive or rigid) specifications, to the sales policies, or external related to the information and...

Resilience, Flexibility and Adaptive Management - - Antidotes for Spurious Certitude? Ecology and Society
Gunderson, Lance; Emory University; lgunder@emory.edu.
In many cases, a predicate of adaptive environmental assessment and management (AEAM) has been a search for flexibility in management institutions, or for resilience in the ecological system prior to structuring actions that are designed for learning. Many of the observed impediments to AEAM occur when there is little or no resilience in the ecological components (e.g., when there is fear of an ecosystem shift to an unwanted stability domain), or when there is a lack of flexibility in the extant power relationships among stakeholders. In these cases, a pragmatic solution is to seek to restore resilience or flexibility rather than to pursue a course of broad-scale, active adaptive management. Restoration of resilience and flexibility may occur through novel...

The effects of stretching on the flexibility, muscle performance and functionality of institutionalized older women BJMBR
Gallon,D.; Rodacki,A.L.F.; Hernandez,S.G.; Drabovski,B.; Outi,T.; Bittencourt,L.R.; Gomes,A.R.S..
Stretching has been widely used to increase the range of motion. We assessed the effects of a stretching program on muscle-tendon length, flexibility, torque, and activities of daily living of institutionalized older women. Inclusion/exclusion criteria were according to Mini-Mental State Examination (MMSE) (>13), Barthel Index (>13) and Lysholm Scoring Scale (>84). Seventeen 67 ± 9 year-old elderly women from a nursing home were divided into 2 groups at random: the control group (CG, N = 9) participated in enjoyable cultural activities; the stretching group (SG, N = 8) performed active stretching of hamstrings, 4 bouts of 1 min each. Both groups were supervised three times per week over a period of 8 weeks. Peak torque was assessed by an...

The Role of Adaptive Management as an Operational Approach for Resource Management Agencies Ecology and Society
Johnson, Barry L; USGS, Upper Midwest Enviromental Sciences Center; barry_johnson@usgs.gov.
In making resource management decisions, agencies use a variety of approaches that involve different levels of political concern, historical precedence, data analyses, and evaluation. Traditional decision-making approaches have often failed to achieve objectives for complex problems in large systems, such as the Everglades or the Colorado River. I contend that adaptive management is the best approach available to agencies for addressing this type of complex problem, although its success has been limited thus far. Traditional decision-making approaches have been fairly successful at addressing relatively straightforward problems in small, replicated systems, such as management of trout in small streams or pulp production in forests. However, this success...
