Dynamique de la biodiversité dans la Serra do Itajaí, Brésil : une approche bioacoustique de la conservation

Le suivi des populations animales et végétales nous a amené à constater une perte importante de la diversité biologique. Les objectifs de la Convention sur la diversité biologique à atteindre pour 2010 sous-tendent la poursuite détaillée de ce suivi à l’échelle mondiale (CBD 2000). Cependant, il est difficile d’avoir une perception d’ensemble de la biodiversité d’un territoire, car les écosystèmes sont des entités dynamiques et évolutives, dans l’espace et dans le temps. Le choix d’un indicateur relevant de l’ensemble des ces caractéristiques devient donc primordial, bien qu’il s’agisse d’une tâche laborieuse. Ce projet propose d’utiliser la bioacoustique comme indicateur environnemental pour faire le suivi des espèces animales en milieu tropical. Afin de faire un suivi à une échelle régionale de la biodiversité, et ce, dans l’un des biomes les plus menacés de la planète, soit celui de la Mata Atlântica brésilienne, ce projet de recherche a comme objectif général de démontrer qu’il est possible d’associer la biophonie (événements sonores), à des événements biologiques (la richesse spécifique animale) en quantifiant des événements sonores (à l’aide des chants produits par les oiseaux, les insectes chanteurs de même que par les anoures) et en tentant de les associer aux fluctuations de la biodiversité. En plus de répondre à cet objectif général, trois objectifs spécifiques ont été définis : 1) comparer la biophonie et l’anthropophonie de milieux soumis à différents niveaux d’anthropisation ou de conservation afin d’évaluer l’impact anthropique sur le milieu, 2) évaluer la variabilité spatiale de la biodiversité, de même que 3) sa variabilité temporelle. Les résultats ont démontré que la biophonie est représentative de la biodiversité d’un milieu, et ce, même dans des conditions de biodiversité maximale puisqu’il existe une très forte relation entre les deux variables. De plus, les résultats révèlent une différence significative dans le ratio anthropophonie/biophonie de milieux soumis à différents niveaux de protection du territoire. La différenciation d’indices de puissance relative (dB/kHz) nous indique également l’importance de la variabilité spatiale et temporelle de la biodiversité, et par conséquent, l’importance de faire le suivi des espèces dans divers milieux et à diverses périodes afin d’obtenir une vision adéquate de la biodiversité régionale.

Utilisation de l’habitat et pressions anthropiques sur une population de rorquals à bosse (Megaptera novaeangliae) de Guadeloupe par suivi terrestre

Le sanctuaire Agoa est une aire marine protégée dans la zone économique exclusive (ZEE) des Antilles françaises qui fut créée en 2010 pour la conservation des mammifères marins et de leurs habitats. Il est connu que le rorqual à bosse fréquente les eaux des Antilles de décembre à mai pour la reproduction et la mise bas. Par contre, peu d’information existe sur l’abondance, le comportement, la distribution et les pressions anthropiques sur cette espèce aux Antilles et encore moins dans le sanctuaire. Cette maîtrise s’intéresse principalement à connaître cette espèce dans un secteur précis de cette aire marine et les liens qu’elle entretient avec certains utilisateurs humains de son habitat. Le tout vise à informer les intervenants en place, autant institutionnels qu’utilisateurs, vers une mise en place de mesures de conservation adaptées. Un suivi terrestre hivernal de plus de 300 heures, en 2012 et 2013, a permis de déterminer l’utilisation de l’habitat et les pressions anthropiques sur une population de rorquals à bosse fréquentant le sud de la péninsule de la Pointe-des-Châteaux en Guadeloupe. Il s’agit du premier suivi terrestre de cette espèce aux Antilles françaises et un des premiers dans l'arc caribéen. La zone d’étude couvre environ 264 km2 et serait une des zones les plus fréquentées de l’archipel guadeloupéen par l’espèce. À l’aide d’un théodolite, la trajectoire de 107 groupes différents (137,8 heures, 699 remontées) a été décrite. Les résultats montrent que la zone d’étude est principalement fréquentée en mars et avril, avec une abondance maximale au début du mois d’avril. La forte présence de baleineaux, particulièrement au mois de mars, pousse à croire que cette zone est utilisée comme pouponnière. Le comportement n’est pas aléatoire dans la zone d’étude et les trajectoires convergent vers certaines zones ayant possiblement un lien avec la bathymétrie. De plus, la zone marine à proximité de la Pointe-des-Châteaux pourrait potentiellement être un lieu de convergence des groupes. Ceux-ci se déplacent à vitesse réduite en direction ENE en général, à l’exception des femelles accompagnées de baleineaux qui prennent une orientation tout autre, c’est-à-dire vers le ONO, et ce à plus grande vitesse. Bien que la pression d’observation soit considérée comme modérée, une forte proportion des remontées se trouve dans les corridors de navigation présents dans la zone d’étude. De plus, le corridor de navigation des navettes entre Saint-François et La Désirade comporte le plus grand risque relatif de collision mortelle. Une réduction de vitesse des embarcations fréquentant le corridor des navettes diminuerait significativement le risque de collision mortelle. Ces pistes de réflexion mèneront sans doute à d’autres études plus poussées afin de continuer à en apprendre sur l’écologie de cette espèce fascinante.

Cuando creces, yo crezco contigo”: La configuración de áreas de protección ambiental y de subjetividades en el Humedal de Córdoba y la vereda El Verjón Bajo

La configuración de lugares como áreas de protección ambiental puede ser vista como un proceso técnico y objetivo, en el que se crean políticas públicas que definen prácticas adecuadas e inadecuadas en el lugar. Pero esta configuración es un proceso histórico y negociado. Este se construye en contante diálogo entre diferentes actores que se preocupan por definir qué es la naturaleza y el cuidado ambiental, y las percepciones que individuos que habitan en o cerca a estos lugares construyen en su diario vivir. Es así como la configuración socioambiental de lugares como áreas de protección ocurre por transformaciones en la forma de percibir un lugar, la relaciones con este y sobre todo, prácticas y relaciones que se traducen en formas de negociar nociones de naturaleza y cuidado ambiental. Esta negociación tiene grandes implicaciones en los individuos, particularmente en su subjetividad. Es decir, en hechos como la forma de nombrarlo, caminarlo, observar las especies, iniciar proyectos de agricultura orgánica, cambiar prácticas productivas, el cerramiento de zonas para proteger las fuentes de agua o zonas de vegetación. También sobre su subjetividad, la manera como se sienten frente al lugar, como juzgan sus acciones y las de otros y cómo construyen objetivos personales con respecto a la idea de cuidado ambiental.

El turismo en los espacios naturales protegidos. Análisis de los objetos de consumo turístico y del comportamiento de los turistas en los parques naturales de Liguria

The objectives of the thesis are identify in the current tourism landscape, tourist typologies which are capable of ensuring an adequate level of sustainability, ie that take into account the need to establish effective partnerships between major players in the touristic sector: 1. Looking for practical examples of more responsible tourism forms with resources. 2. Stressing the role played by ecotourism, this form of tourism according to the qual makes your holiday visitors relate more directly conscious of environmental and sociocultural present in the venue. 3. identifying actions to ensure the protection of the environment and the economic take off by traditionally depressed areas. 4. identifying objects aimed at boosting tourism consumption of a natural protected area interpreted as ideal as post-Fordist real space and identify profiles of tourists in protected areas. Also if tourism products linked to nature, culture and cuisine can help to revitalize the Ligurian coastal tourism 5. Checking if the regional system of protected areas has produced results in both environmental protection and endogenous development through tourism. 6. Quantifying the actual supply of the areas studied. 7. Checking if the three parks studied were identified and developed specific objects of tourist consumption.

Nature protection in Greece: an appraisal of the factors shaping integrative conservation and policy effectiveness

The proliferation of designated areas following the implementation of Natura 2000 in Greece has initiated changes in the protected area design and conservation policy making aiming at delivering action for biodiversity and integrative planning on a wider landscape. Following the sustainability concept, an integrative approach cannot realistically take place simply by extending the protected area and designations. The paper addresses public involvement and inter-sectoral coordination as major procedural elements of integrative management and evaluates the nature and strength of their negative or positive influences on the fulfillment of an integrative vision of nature conservation. A review of the history of protected areas and administration developments in Greece provide useful input in the research. The analysis has shown that the selected network of Natura 2000 sites has been superimposed upon the existing system and resulted in duplication of administrative effort and related legislation. As a result the overall picture of protected areas in the country appears complex, confusing and fragmented. Major failures to integrated conservation perspective can be traced to structural causes rooted in politico-economic power structures of mainstream policy and in a rather limited political commitment to conservation. It is concluded that greater realisation. of integrated conservation in Greece necessitates policy reforms related mainly to sectoral legal frameworks to promote environmentalism as well as an increased effort by the managing authorities to facilitate a broader framework of public dialogue and give local communities incentives to sustainably benefit from protected areas.

PGR forum: serving the crop wild relative user community

The Euro-Mediterranean region is an important centre for the diversity of crop wild relatives. Crops, such as oats (Avena sativa), sugar beet (Beta vulgaris), apple (Malus domestica), annual meadow grass (Festuca pratensis), white clover (Trifolium repens), arnica (Arnica montana), asparagus (Asparagus officinalis), lettuce (Lactuca sativa), and sage (Salvia officinalis) etc., all have wild relatives in the region. The European Community funded project, PGR Forum (www.pgrforum.org) is building an online information system to provide access to crop wild relative data to a broad user community; including plant breeders, protected area managers, policy-makers, conservationists, taxonomists and the wider public. The system will include data on uses, geographical distribution, biology, population and habitat information, threats (including IUCN Red List assessments) and conservation actions. This information is vital for the continued sustainable utilisation and conservation of crop wild relatives. Two major databases have been utilised as the backbone to a Euro-Mediterranean crop wild relative catalogue, which forms the core of the information system: Euro+Med PlantBase (www.euromed.org.uk) and Mansfeld’s World Database of Agricultural and Horticultural Crops (http://mansfeld.ipk-gatersleben.de). By matching the genera found within the two databases, a preliminary list of crop wild relatives has been produced. Around 20,000 of the 30,000+ species listed in Euro+Med PlantBase can be considered crop wild relatives, i.e. those species found within the same genus as a crop. The list is currently being refined by implementing a priority ranking system based on the degree of relatedness of taxa to the associated crop.

Protecting developing countries' forests: enforcement in theory and practice

This paper relates the key findings of the optimal economic enforcement literature to practical issues of enforcing forest and wildlife management access restrictions in developing countries. Our experiences, particularly from Tanzania and eastern India, provide detail of the key pragmatic issues facing those responsible for protecting natural resources. We identify large gaps in the theoretical literature that limit its ability to inform practical management, including issues of limited funding and cost recovery, multiple tiers of enforcement and the incentives facing enforcement officers, and conflict between protected area managers and rural people's needs.

Making robust policy decision using global biodiversity indicators

In order to influence global policy effectively, conservation scientists need to be able to provide robust predictions of the impact of alternative policies on biodiversity and measure progress towards goals using reliable indicators. We present a framework for using biodiversity indicators predictively to inform policy choices at a global level. The approach is illustrated with two case studies in which we project forwards the impacts of feasible policies on trends in biodiversity and in relevant indicators. The policies are based on targets agreed at the Convention on Biological Diversity (CBD) meeting in Nagoya in October 2010. The first case study compares protected area policies for African mammals, assessed using the Red List Index; the second example uses the Living Planet Index to assess the impact of a complete halt, versus a reduction, in bottom trawling. In the protected areas example, we find that the indicator can aid in decision-making because it is able to differentiate between the impacts of the different policies. In the bottom trawling example, the indicator exhibits some counter-intuitive behaviour, due to over-representation of some taxonomic and functional groups in the indicator, and contrasting impacts of the policies on different groups caused by trophic interactions. Our results support the need for further research on how to use predictive models and indicators to credibly track trends and inform policy. To be useful and relevant, scientists must make testable predictions about the impact of global policy on biodiversity to ensure that targets such as those set at Nagoya catalyse effective and measurable change.

A new species of the lizard genus Bachia (Squamata : Gymnophthalmidae) from the Cerrados of Central Brazil

A new species of Bachia of the bresslaui group, is described from Estacao Ecologica Serra Geral do Tocantins, a recently created protected area in the Central Brazilian Cerrados of state of Tocantins. The new species is most similar to Bachia psamophila from which it differs in limb morphology and head and body scalation. As in Bachia psamophila the shovel-shaped snout of the new species is highly prominent, an adaptation related to its psamophilous habits.

Governança ambiental e unidades de conservação do meio ambiente: uma abordagem institucionalista

Os esforços de conservação ambiental têm enfrentado muitos desafios, dentre os quais a dificuldade para implementar áreas protegidas. As evidências sugerem que a criação legal de uma área protegida não é condição suficiente para sua efetiva implementação. O presente trabalho adota uma abordagem institucionalista para entender as condições que poderiam levar ao sucesso ou ao fracasso de tais áreas. O arcabouço teórico é composto por trabalhos de Direito Ambiental, Biologia da Conservação e, principalmente, da Nova Economia Institucional. Inicialmente, busca-se reunir estes diversos campos do conhecimento sob um mesmo corpo de conhecimento, a Governança ambiental. Em seguida, formula-se uma hipótese de complementaridade institucional, i.e., a possibilidade de que exista sinergia na interação entre determinadas instituições. Esta discussão é utilizada para analisar a legislação brasileira referente às Unidades de Conservação. E, por fim, as hipóteses teóricas são examinadas em um estudo de caso da região de Mata Atlântica no Vale do Ribeira, São Paulo.

Conselhos gestores em unidades de conservação: caracterização da efetividade na perspectiva dos stakeholders

A participação de atores sociais na governabilidade e na aplicabilidade de políticas públicas no Brasil é tema recorrente em debates da gestão pública (SANTANA, 2011; TENÓRIO, 2002; NASCIMENTO, 1967), e tem sido defendida por organismos de defesa da sustentabilidade e da preservação ambiental como elemento imprescindível para a gestão de territórios naturais (VAN DE KERKHOF, 2006; UICN, 2011; HOCKINGS ET AL, 2006; BRASIL, 2013; ERVIN, 2003a; BRASIL, 2002; 2014). Para a política ambiental em vigência no Brasil, os conselhos gestores de políticas públicas, tradicionais espaços de consulta e controle social das políticas públicas, encontram-se legalmente institucionalizados como fóruns para garantir a participação de atores sociais na gestão das chamadas unidades de conservação, as UCs (BRASIL, 2000; 2002). Entretanto, o respaldo institucional não se traduz por si só em participação social na gestão destes territórios e o cenário é o de um grau reduzido de conselhos gestores em atividade. O presente trabalho assumiu o desafio de identificar os aspectos que caracterizam a efetividade dos conselhos gestores em sua atuação, sob a perspectiva dos atores que integram estes espaços. Para tanto, foi aplicada uma metodologia de caráter exploratório, adotando-se métodos de análise qualitativa a partir da aplicação de entrevistas semiestruturadas em profundidade. Com o apoio de especialistas em gestão socioambiental, identificou-se conselhos gestores apontados como referências por sua efetividade. E, a partir da perspectiva de especialistas e dos atores que integram tais conselhos gestores em atividade (stakeholders), foi possível compreender variáveis determinantes e fatores como instrumentos e dinâmicas que contribuem para uma atuação efetiva. Concluiu-se que o arcabouço legal e institucional que respalda a existência dos conselhos em unidades de conservação é significativo ao favorecer o envolvimento da sociedade civil, organizações sem fins lucrativos e poder público na gestão de áreas naturais, mas não se traduz por si só em conselhos gestores autônomos e em atividade como fóruns de consulta ou deliberação de questões de interesse para a gestão. Sob a ótica dos stakeholders, a efetividade engloba tanto as ações que geram resultados para a preservação e para o manejo sustentável dos recursos naturais quanto a própria capacidade de existir como um fórum legítimo de debates e de participação social local.

Caracterização ecológica dos peixes recifais do Atol das Rocas

The present work was carried out at the Atol das Rocas (3º 51 S; 33º 49 W), the only atoll of the South Atlantic and the first Brazilian marine protected area. It was guided by the following hypothesis: the composition of the fish communities varies in agreement with the position of the pools; in other words, with or without permanent ocean connection. To test the validity of this hypothesis, the fish abundance was estimated in the connected pools (Barretinha/Barreta Falsa) and unconnected ones (Cemiteriozinho/Âncoras), carrying an ecological characterization of the fishes that inhabit these pools. Additionally, the structural complexity of the sampled places was also evaluated intending to verify the variations of the abundance and diversity of fishes in function to this factor. By the fact of this research was being carried out through the limits of a conservation unit, the samples was realized using visual census techniques. The results generated through uni and multivariate analytic techniques allowed the evidence that decisive factor in the density, richness and diversity variations of fishes are linked to the substratum type (Hard / Soft bottom) and not by the fact that the pool are or are not connected permanently to the ocean. In relation to the structural complexity; 58% of the variations in the diversity of fishes were attributed to changes in the structural complexity, while 12% of the variations in the abundance were attributed to the structural complexity
