BEEHOPE: um projeto de conservação das subespécies nativas de abelha da Europa Ocidental (linhagem M) à escala Europeia

O projeto BEEHOPE, com o título original “Honeybee conservation centres in western Europe - an innovative strategy using sustainable beekeeping to reduce honeybee decline”, foi um dos 10 aprovados na área da biodiversidade do 5º concurso transnacional (2013-2014) BiodivErsA/FACCE-JPI (http://www.biodiversa.org/766), subordinado ao tema “Promover sinergias e reduzir o compromisso entre o abastecimento de alimentos, biodiversidade e serviços dos ecossistemas”. A diversidade nativa das populações de abelha melífera (Apis mellifera) da linhagem da Europa ocidental (M) tem vindo a ser crescentemente ameaçada pela introdução massiva de colónias da linhagem da Europa oriental (C, onde se incluem as subespécies A. m. ligustica, A. m. carnica, A. m. macedónica etc.), e também por outros fatores bióticos (Varroa e vírus associados, Nosema etc.) e abióticos (pesticidas, perda e fragmentação de habitat, alterações climáticas etc.). É neste contexto que surge o projeto BEEHOPE, o qual tem por objetivo último contribuir para a conservação da diversidade genética das populações de abelha melífera da linhagem M.info:eu-repo/semantics/publishedVersio

Algorithmic Information Theory-Based Analysis of Earth Observation Images: An Assessment

Earth observation images can be analyzed by a number of techniques. Information theory allows us to conceive algorithmic analyses of satellite images

Object Oriented Simulation: Highlights on The PROSIT Parallel Discrete Event Simulator

The Prosit project, launched in 1991, is devoted to the development of a new discrete event simulation system based on the object paradigm. Object orientation is used to ensure two main concerns: ffl performance on both conventional and multiprocessor machines ffl versatility and ease of use. In particular, Prosit user programs (models and experiment descriptions) should need only a new compilation so as to run efficiently on either a single monoprocessor workstation, a cluster of workstations or a multi-processor machine. This paper describes the design status of the project. It discusses the implementation strategies for several key aspects of the project. Rather than the model architecture that was presented and discussed in (MM93), it details the Prosit simulation environement architecture and addresses many aspects of distributed object oriented programming

Observer, évaluer et suivre la biodiversité sous marine des lagons : Intérêt des techniques vidéo rotatives en haute dé:nition. Où en est-on en Nouvelle-Calédonie ?

This article first draws up a balance sheet of all various implemented techniques to observe and monitor the shallow marine biodiversity. Then the article focuses on the techniques of the rotating high resolution submarine video and their implementation in New Caledonia on various sites and habitats under various management / protection policies such as Marines Protected Areas, strict marine reserves, registered sites on UNESCO world heritage or free access zones. An evaluation of these techniques and of their contributions is proposed in terms of transfer to other geographical zones, of practical feasibility in the technical, logistic and cost point of view as also are analyzed the perspectives offered by those technologies in terms of innovation, of support for the management or as communication tool on the health of the observed biodiversity.Cet article dresse tout d’abord un bilan des différentes techniques mises en oeuvre pour observer et suivre la biodiversité marine peu profonde. Ensuite l’article se focalise sur les techniques de la vidéo sous marine rotative de haute définition et leur mise en œuvre en Nouvelle-Calédonie sur différents sites et habitats soumis ou non à des règles de gestion/protection tels que des Aires Marines Protégées, des réserves intégrales ou des sites inscrits au patrimoine mondial. Une évaluation de ces techniques et de leur apports est proposée en termes de transfert à d’autres zones géographiques, de faisabilité pratique aux plans techniques, logistiques et de coût comme également sont analysées les perspectives en termes d’innovation, d’appui à la gestion ou encore d’outil de communication sur les états de la biodiversité observée
