Ecology of neotropical mistletoes: an important canopy-dwelling component of Brazilian ecosystems Acta Botanica
Arruda,Rafael; Fadini,Rodrigo Ferreira; Carvalho,Lucélia Nobre; Del-Claro,Kleber; Mourão,Fabiana Alves; Jacobi,Claudia Maria; Teodoro,Grazielle Sales; Berg,Eduardo van den; Caires,Claudenir Simões; Dettke,Greta Aline.
Mistletoes have been studied in temperate countries regularly because they can be pests of cultivated plants and forest plantations. In comparison with temperate habitats, little is known about the ecology of mistletoes in the Neotropics. More emphasis should be given to neotropical mistletoes because they could be important elements of plant communities, acting as key resources for pollinators, seed dispersers and herbivores. Using a combination of findings from early mistletoe studies and empirical evidence from several recent case studies, we report emerging patterns of mistletoe interactions with associated organisms and propose aims for further studies. There has been increasing interest in working with mistletoes in Brazil. Although there are some...

Learning in Adaptive Management: Insights from Published Practice Ecology and Society
Fabricius, Christo; Sustainability Research Unit, Nelson Mandela Metropolitan University, South Africa; christo.fabricius@nmmu.ac.za; Cundill, Georgina; Department of Environmental Science, Rhodes University, Grahamstown, South Africa; georgina.cundill@gmail.com.
Adaptive management is often advocated as a solution to understanding and managing complexity in social-ecological systems. Given the centrality of learning in adaptive management, it remains unclear how learning in adaptive management is understood to occur, who learns, what they learn about, and how they learn. We conducted a systematic review using the Thomson Reuters Web of Science, and searched specifically for examples of the practical implementation of adaptive management between 2011 and 2013, i.e., excluding articles that suggested frameworks, models, or recommendations for future action. This provided a subset of 22 papers that were analyzed using five elements: the aims of adaptive management as stated in each paper; the reported achievements...

Structure et connectivité de la mégafaune marine à l’échelle d’une région océanique. Enjeux pour la gestion durable des tortues vertes dans l’océan Indien occidental ArchiMer
Bourjea, Jerome.
This thesis is a comprehensive work aiming to improve scientific knowledge on the green turtle (Chelonia mydas) in order to provide key scientific evidences needed for the implementation of coherent and effective management measures to protect at the Western Indian Ocean scale this threatened species. In a first step, this work aimed to established baseline data on the abundance of green turtles nesting females and long term trends of some key nesting populations of the region by applying different modelling methods. In a second step, this work determined the regional genetic structure of this species and the relationships that exists between the different populations. Finally, the conservation of marine turtles being closely dependant to external...
