Implementation of Marine Protected Areas as a governability challenge in Southern Brazil

Marine Protected Areas (MPAs) have been endorsed internationally as a tool promoting marine conservation. MPAs implementation can however be challenging, with many not achieving conservation objectives while creating conflicts with small-scale fishers, often overlooked. This study aims at exploring how MPA implementation can be improved, taking as a case study the Marine National Park of Currais Islands in Southern Brazil. Specifically, this thesis offers a theoretical contribution by applying the interactive governance framework to analyze both the natural and the social systems, focusing on small-scale fishers, governed by the MPA as an institution. The thesis also presents a methodological contribution, as it develops and applies an exploratory mapping approach. We surveyed 65 small-scale fishers from eight communities at Pontal do Paraná municipality, and conducted an exploratory mapping approach in small groups. Main findings point to challenges and opportunities to MPA implementation, and offer a way to involve small-scale fishers in the discussion about MPAs.

Coastline evolution rates of Portugal

Regional/global-scale information on coastline rates of change and trends is extremely valuable, but national-scale studies are scarce. A widely accepted standardized methodology for analysing long-term coastline change has been difficult to achieve, but is essential to conduct an integrated and holistic approach to coastline evolution and hence support coastal management actions. Additionally, databases providing knowledge on coastline evolution are of key importance to support both coastal management experts and users. The main objective of this work is to present the first systematic, global and consistent long-term coastline evolution data of Portuguese mainland low-lying sandy. The methodology used quantifies coastline evolution using an unique and robust coastline indicator (the foredune toe), which is independent of short-term changes. The dataset presented comprises: 1) two polyline sets, mapping the 1958 and 2010 sandy beach-dune systems coastline, both optimized for working at 1:50 000 scale or smaller, and 2) one polyline set representing long-term change rates between 1958 and 2010, estimated at each 250 m. Results show beach erosion as the dominant trend, with a mean change rate of -0.24 ± 0.01 m/year for all mainland Portuguese beach-dune systems. Although erosion is dominant, this evolution is variable in signal and magnitude in different coastal sediment cell and also within each cell. The most relevant beach erosion issues were found in the coastal stretches of Espinho - Torreira and Costa Nova - Praia da Mira, both at sub-cell 1b; Cova Gala - Leirosa, at sub-cell 1c and Cova do Vapor - Costa da Caparica, at cell 4. Cells 1 and 4 exhibit a history of major human interventions interfering with the coastal system, many of which originated and maintained a sediment deficit. In contrast, cells 5 and 6 have been less intervened and show stable or moderate accretion behaviour.

Social Decision-Making in Bonobos and Chimpanzees

Humans are natural politicians. We obsessively collect social information that is both observable (e.g., about third-party relationships) and unobservable (e.g., about others’ psychological states), and we strategically employ that information to manage our cooperative and competitive relationships. To what extent are these abilities unique to our species, and how did they evolve? The present dissertation seeks to contribute to these two questions. To do so, I take a comparative perspective, investigating social decision-making in humans’ closest living relatives, bonobos and chimpanzees. In Chapter 1, I review existing literature on theory of mind—or the ability to understand others’ psychological states—in these species. I also present a theoretical framework to guide further investigation of social cognition in bonobos and chimpanzees based on hypotheses about the proximate and ultimate origins of their species differences. In Chapter 2, I experimentally investigate differences in the prosocial behavior of bonobos and chimpanzees, revealing species-specific prosocial motivations that appear to be less flexible than those exhibited by humans. In Chapter 3, I explore through decision-making experiments bonobos’ ability to evaluate others based on their prosocial or antisocial behavior during third-party interactions. Bonobos do track the interactions of third-parties and evaluate actors based on these interactions. However, they do not exhibit the human preference for those who are prosocial towards others, instead consistently favoring an antisocial individual. The motivation to prefer those who demonstrate a prosocial disposition may be a unique feature of human psychology that contributes to our ultra-cooperative nature. In Chapter 4, I investigate the adaptive value of social cognition in wild primates. I show that the recruitment behavior of wild chimpanzees at Gombe National Park, Tanzania is consistent with the use of third-party knowledge, and that those who appear to use third-party knowledge receive immediate proximate benefits. They escape further aggression from their opponents. These findings directly support the social intelligence hypothesis that social cognition has evolved in response to the demands of competing with one’s own group-mates. Thus, the studies presented here help to better characterize the features of social decision-making that are unique to humans, and how these abilities evolved.

Floristic And Ethnobotanical Studies Of Medicinal Plants Of The City Of El -Jadida (MOROCCO)

Abstract: BRIGUICHE. H, ZIDANE. L. Floristic And Ethnobotanical Studies Of Medicinal Plants Of The City Of El -Jadida (MOROCCO). In the framework of the ethnobotanical studies on medicinal plants undertaken by the Laboratory of Biodiversity and Natural Resources of the Faculty of Sciences of Kenitra (Morocco), we are interested in the area of El Jadida which presents a rather important floristic richness thanks to changes in its ecological conditions By using 204 questionnaire, the ethnobotanical surveys were conducted in the field during the years 2012-2013. The location of the different sampling sites was determined by the stratified sampling method. The analysis of the results obtained from the questionnaires and forms using statistical processing allowed us to identify 70 plant species distributed in 69 genera and 37 families. These results also show that most of these species are mainly used in the care of the digestive system and respiratory system. The seed is the most used part in local traditional medicines and the decoction is the most frequent mode with a rate of 31%. The species Origanum compactum is the most used by the population of the city of El Jadida 47 quotes.  

Ecophysiology of Adonis distorta, a high-mountain species endemic of the Central Apennines

Morphological, anatomical and physiological plant and leaf traits of A. distorta, an endemic species of the Central Apennines on the Majella Massif, growing at 2,675 m a.s.l, were analyzed. The length of the phenological cycle starts immediately after the snowmelt at the end of May, lasting 128 ± 10 days. The low A. distorta height  (Hmax= 64 ± 4 mm) and total leaf area (TLA= 38 ± 9 cm2) associated to a high leaf mass area (LMA =11.8±0.6 mg cm−2) and a relatively high leaf tissue density (LTD = 124.6±14.3 mg cm−3) seem to be adaptive traits to the stress factors of the environment where it grows. From a physiological point of view, the high A. distorta photosynthetic rates (PN =19.6 ± 2.3 µmol m−2 s−1) and total chlorophyll content (Chla+b = 0.88 ± 0.13 mg g−1) in July are justified by the favorable temperature. PN decreases by 87% in September at the beginning of plant senescence. Photosynthesis and leaf respiration (RD) variations allow A. distorta to maintain a positive carbon balance during the growing season becoming indicative of the efficiency of plant carbon use. The results could be an important tool for conservation programmes of the A. distorta wild populations.

What happens at the gap between knowledge and practice? Spaces of encounter and misencounter between environmental scientists and local people

Researchers studying processes of global environmental change are increasingly interested in their work having impacts that go beyond academia to influence policy and management. Recent scholarship in the conservation sciences has pointed to the existence of a research-action gap and has proposed various solutions for overcoming it. However, most of these studies have been limited to the spaces of dissemination, where the science has already been done and is then to be passed over to users of the information. Much less attention has been paid to encounters that occur between scientists and nonscientists during the practice of doing scientific research, especially in situations that include everyday roles of labor and styles of communication (i.e., fieldwork). This paper builds on theories of contact that have examined encounters and relations between different groups and cultures in diverse settings. I use quantitative and qualitative evidence from Madidi National Park, Bolivia, including an analysis of past research in the protected area, as well as interviews (N = 137) and workshops and focus groups (N = 12) with local inhabitants, scientists, and park guards. The study demonstrates the significance of currently unacknowledged or undervalued components of the research-action gap, such as power, respect, and recognition, to develop a relational and reciprocal notion of impact. I explain why, within such spaces of encounter or misencounter between scientists and local people, knowledge can be exchanged or hidden away, worldviews can be expanded or further entrenched, and scientific research can be welcomed or rejected.

Évaluation de la modélisation de la taille de grain de neige du modèle multi-couches thermodynamique SNOWPACK: implication dans l'évaluation des risques d'avalanches

Résumé: L’Institut pour l'étude de la neige et des avalanches en Suisse (SLF) a développé SNOWPACK, un modèle thermodynamique multi-couches de neige permettant de simuler les propriétés géophysiques du manteau neigeux (densité, température, taille de grain, teneur en eau, etc.) à partir desquelles un indice de stabilité est calculé. Il a été démontré qu’un ajustement de la microstructure serait nécessaire pour une implantation au Canada. L'objectif principal de la présente étude est de permettre au modèle SNOWPACK de modéliser de manière plus réaliste la taille de grain de neige et ainsi obtenir une prédiction plus précise de la stabilité du manteau neigeux à l’aide de l’indice basé sur la taille de grain, le Structural Stability Index (SSI). Pour ce faire, l’erreur modélisée (biais) par le modèle a été analysée à l’aide de données précises sur le terrain de la taille de grain à l’aide de l’instrument IRIS (InfraRed Integrated Sphere). Les données ont été recueillies durant l’hiver 2014 à deux sites différents au Canada : parc National des Glaciers, en Colombie-Britannique ainsi qu’au parc National de Jasper. Le site de Fidelity était généralement soumis à un métamorphisme à l'équilibre tandis que celui de Jasper à un métamorphisme cinétique plus prononcé. Sur chacun des sites, la stratigraphie des profils de densités ainsi des profils de taille de grain (IRIS) ont été complétés. Les profils de Fidelity ont été complétés avec des mesures de micropénétromètre (SMP). L’analyse des profils de densité a démontré une bonne concordance avec les densités modélisées (R[indice supérieur 2]=0.76) et donc la résistance simulée pour le SSI a été jugée adéquate. Les couches d’instabilités prédites par SNOWPACK ont été identifiées à l’aide de la variation de la résistance dans les mesures de SMP. L’analyse de la taille de grain optique a révélé une surestimation systématique du modèle ce qui est en accord avec la littérature. L’erreur de taille de grain optique dans un environnement à l’équilibre était assez constante tandis que l’erreur en milieux cinétique était plus variable. Finalement, une approche orientée sur le type de climat représenterait le meilleur moyen pour effectuer une correction de la taille de grain pour une évaluation de la stabilité au Canada.

Estudo preliminar sobre a densidade de primatas no sul do Parque Nacional das Quirimbas, Moçambique

O Parque Nacional das Quirimbas (PNQ) é a primeira e única área com estatuto de Parque Nacional no norte de Moçambique. A necessidade de estudar mamíferos de médio e grande porte fez deste trabalho o primeiro estudo dedicado à densidade de primatas no sul do PNQ. De Outubro de 2014 a Janeiro de 2015 foram realizados, em duas áreas do sul do PNQ, Taratibu e Mareja, censos segundo o método de amostragem de distâncias de transectos lineares. As densidades estimadas de cada uma das espécies estudadas, Papio cynocephalus, Cercophitecus albogularis e Chlorocebus pygerythrus, revelaram ser mais elevadas em Mareja do que em Taratibu, área caracterizada pela presença de inselbergs. No total das duas áreas de estudo (sul do PNQ) a estimativa da densidade foi de 12,4855 indivíduos/km2 para P. cynocephalus, de 2,8700 indivíduos/km2 para C. albogularis e de 0,5172 indivíduos/km2 para C. pygerythrus. Estas estimativas quando comparadas com o único estudo geral sobre a densidade de mamíferos presente no PNQ, revelam ser mais elevadas. Uma vez que o método utilizado no presente estudo, permitiu uma maior facilidade na visualização direta de primatas e um maior número de indivíduos avistados, podemos concluir que estes valores de estimativas de densidade poderão ser mais fiáveis que os obtidos anteriormente para esta zona. As densidades obtidas quando comparadas com outros estudos mostram ser mais elevadas no caso P. cynocephalus, o que poderá fazer do PNQ uma área de valor inestimável e de grande importância para a conservação desta espécie, e mais baixas no que toca à espécie C. albogularis, o que poderá indicar um declíneo desta população. Relativamente a C. pygerythrus, ainda que o número de avistamentos tenha sido reduzido, a estimativa da densidade obtida segue a tendência de estabilidade da população.

Mito e historia: incursiones en la leyenda canaria La pared de Roberto

[es] Una de las manifestaciones relativas a la literatura de tradición oral de la isla de La Palma (Canarias) que se encuentra pendiente de estudio es la referida a las leyendas. Durante la segunda mitad del siglo xix, un destacado grupo de escritores rescató media docena de estas narraciones y las formalizó en algunas versiones impresas. Desde entonces, las mismas han quedado fijadas como el canon de leyendas «clásicas» de La Palma. Una de ellas es la que toca con la Pared del Diablo o de Roberto, en la Cumbre de los Andenes, en el borde superior del parque nacional de la Caldera de Taburiente. En la actualidad esta leyenda se mantiene como un relato trufado de contenidos románticos. Con el fin de profundizar en las raíces y la evolución de esta leyenda se realiza una descripción, inventario y análisis de las distintas versiones localizadas que abren nuevos horizontes de reflexión sobre cuestiones fundamentales en torno a conceptos como mito e historia, lengua y escritura, individuo y pueblo. [en] One of the manifestations related to the oral literary tradition of the island of La Palma (Canaries) which remains under study is the legendary genre. During the second half of the nineteenth century, an outstanding group of writers rescued half a dozen of these stories and formalized them in some printed versions. Since then, they have been set up as the canon of «classical» legends of La Palma. One of them deals with the wall of the Devil or the wall of Roberto, at the Cumbre de los Andenes, on the upper edge of the National Park Caldera de Taburiente. Today this legend continues to be a story charged with romantic nuances. In order to deepen into the roots and evolution of this legend, we have carried out a description, inventory and analysis of the different discovered versions, opening new horizons of reflection on fundamental questions regarding concepts such as myth and history, language and writing, individual and people.

Governança ambiental e turismo: a participação de atores no Parque Nacional Tortuguero, Costa Rica

A experiência na construção da governança ambiental em torno do Parque Nacional Tortuguero na Costa Rica é a questão principal deste artigo. A mesma será analisada a partir da implementação do Conselho Local de Tortuguero/Setor Oeste e das articulações de atores do Setor Costeiro, notadamente, onde há incidência maior de turismo. Estruturou-se este artigo com base em pesquisas qualitativas, a exemplo de coleta de informações da bibliografia especializada, de dados documentais, legais e também via entrevistas. Por meio de tais movimentos, identificou-se uma série de ações relacionadas à conservação do meio ambiente e do turismo, dentro de uma perspectiva sustentável. Entretanto, em que pese os avanços alcançados, constata-se ainda a necessidade de se empreender mais esforços por parte de todos os envolvidos, sobretudo do Estado e na sua interação com os demais atores, pois persistem problemas diversos que são, historicamente, são insustentáveis a pensar-se em manejo do meio ambiente.

Minería de oro en el marco de la inseguridad normativa, los grupos de interés y las zonas de exclusión

En este artículo se aborda el tema de la minería en zonas excluibles, por medio de una revisión bibliográfica de la legislación vigente, y se ejemplifican dos casos icono que se han presentado en Colombia en relación con la minería de oro en áreas de protección: el Parque Nacional Yaigojé-Apaporis y el Páramo de Santurbán. En ambos casos se evidencia la falta de coordinación entre las autoridades mineras y ambientales, y el vacío legislativo especialmente en la fase exploratoria, que, además de causar serios impactos ambientales y vulnerar los derechos de minorías étnicas y la población en general, crea inseguridad normativa y grandes costos a las empresas mineras. En un primer momento se describe el panorama jurídico que rige la explotación minera en Colombia, seguido de un contexto técnico del ciclo minero y de las implicaciones desde el punto de vista jurídico de este tipo de explotaciones en áreas protegidas. Luego, se presenta una cronología de los estudios de caso de la minería en un área protegida del sistema de Parques Nacionales y otra de carácter regional, concluyendo que la falta de coordinación entre instituciones deja al sector en un limbo jurídico.
