Long-term fish community response to a reach-scale stream restoration

At a global scale, aquatic ecosystems are being altered by human activities at a greater rate than at any other time in history. In recent years, grassroots efforts have generated interest in the restoration of degraded or destroyed aquatic habitats, especially small wetlands and streams where such projects are feasible with local resources. We present ecological management lessons learned from 17 years of monitoring the fish community response to the channel relocation and reach-level restoration of Juday Creek, a 3rd-order tributary of the St. Joseph River in Indiana, USA. The project was designed to increase habitat complexity, reverse the effects of accumulated fine sediment (< 2 mm diameter), and mitigate for the impacts of a new golf course development. The 1997 restoration consisted of new channel construction within two reaches of a 1.2-km section of Juday Creek that also contained two control reaches. A primary social goal of the golf course development and stream restoration was to avoid harm to the non-native brown trout fishery, as symbolic of community concerns for the watershed. Our long-term monitoring effort revealed that, although fine sediment increased over time in the restored reaches, habitat conditions have promoted the resurgence of native fish species. Since restoration, the fish assemblage has shifted from non-native Salmonidae (brown trout, rainbow trout) to native Centrarchidae (rock bass, largemouth bass, smallmouth bass). In addition, native, nongame species have remained stable or have increased in population abundance (e.g., Johnny darter, mottled sculpin). The results of this study demonstrate the value of learning from a restoration project to adjust management decisions that enhance environmental quality.

The Effect of Marine Protected Areas on Fishers' Income in the Philippines

The fisheries sector is vital to the Philippine economy, providing substantial employment and income, contributing export earnings, and meeting local food security and nutrition requirements. To protect coastal and marine habitat and to sustain fisheries, over 1000 marine protected areas (MPAs) have been established, in the Philippines. This paper provides empirical evidence on the variance of net revenues linked with MPA establishment and the possible range of relocation costs for fishing effort displaced by an MPA. A total of 424 households were randomly selected from 18 barangays (villages) adjacent to MPAs in three regions in the Philippines. Results show that incomes decrease significantly for both fulltime and seasonal types of fishers after 1-3 years of MPA establishment. The loss occurring through MPA is higher than expected and at least on the short run (up to 4 years) the spill-over effect does not compensate. This information helped to determine the necessary conditional cash transfers for coastal communities who are highly dependent on coastal and marine resources.

Globale Entwikclung als Lernbereich in den Naturwissenschaften

Mit dem Orientierungsrahmen für den Lernbereich Globale Entwicklung wurden Anregungen gegeben, die Themen nachhaltige Entwicklung und globale Entwicklung im Unterricht in allen Schulfächern aufzugreifen. Die drei naturwissenschaftlichen Schulfächer Biologie, Chemie und Physik haben sich bislang sehr unterschiedlich auf das Thema eingelassen. In der Biologiedidaktik finden sich sowohl Forschungsarbeiten als auch Unterrichtsvorschläge; für Chemie und insbesondere Physik existieren hingegen nur sehr wenige Ansätze. Im Rahmen der zu erwerbenden Bewertungskompetenz, wie sie durch die Bildungsstandards in den Fächern Biologie, Chemie und Physik beschrieben wird, ist nachhaltige Entwicklung als ein mögliches Thema, ein Kontext anzusehen. Vor diesem größeren Hintergrund wird die gängige unterrichtspraktische Literatur in allen drei Fächern exemplarisch zusammengefasst. (DIPF/Orig.)

The New Scots: Migration and Diaspora in Scottish Poetry.

This chapter examines the poetry of Scottish South Asians, the "New Scots" who bring a whole history of displacement, dislocation and relocation with them, as their memory of the "elsewhere" enters their writing. Their voices are significant as they embody multicultural Scotland with postcolonial dialects that signify an encounter in the Third Space where they are affected by and affect the "host" community. This chapter will question whether the writing of "New Scots" has added more than just "colour" to Scottish Poetry, as it traces the recent migrant history and analyses the lives and "voices" of diasporic communities as evident in their poetry. The objective is to assess how the new "voices" have blended in, expanded and/or challenged the boundaries of what defines Scottish Poetry, and determine whether they form a "community" of poets distinguished by the complexity of their regional allegiances, both past and present.

Desafios para a conquista do direito à moradia digna no assentamento Ilha

This booklet has been prepared from the actions for the university extension project entitled "Housing and Environment: building dialogue on urbanization of the settlement Ilha”. The study was conducted in a community located on the south end of the city of Almirante Tamandaré, among Barigui and Tanguá rivers. This project was conducted by a group of professors and students of the Federal University of Technology - Paraná (UTFPR), Campus Curitiba. The main objective was to investigate ways of intervention in housing and urbanization of the settlement Ilha, for the regularization of their properties. However, throughout the project, the group found that regularization of this settlement was not possible, in view of the risk of flooding on site. Therefore, this booklet provides information about the area and the rivers in their surroundings, on the positive aspects of living there, brings the story of some struggles of residents for better living conditions, as well as suggestions of funding sources for facilitating a possible relocation of existing families.

Perspective d'un développement rural durable : le cas des Hmongs du Laos

Résumé : Le développement durable est un processus d'évolution dans lequel toutes les ethnies coexistent en harmonie avec un environnement sain. Depuis une quarantaine d'années, le Laos a connu de nombreux bouleversements. Des groupes minoritaires, dont les Hmongs, ont subi les contrecoups des changements socio-politiques et économiques. Les Hmongs, qui habitent les régions montagneuses et qui pratiquent l'agriculture itinérante, sont particulièrement touchés par des inégalités économiques et sociales malgré la politique d'égalité ethnique. Les transformations progressives de leur méthode d'utilisation du sol, de leur mode de production et de leur mode de vie itinérants en sédentarisation durable deviennent fondamentales et cruciales. Les Hmongs défavorisés aspirent fortement à de meilleures conditions de vie tout comme les populations qui vivent dans les plaines. En effet, les Hmongs, qui habitent dans les régions de Lakhasipsong et de Longsan, province de Vientiane, s'adaptent aux nouvelles conditions de transformation socio-économique, soient la sédentarisation du mode de production et du mode de vie. On peut affirmer que le développement rural et communautaire permet la sédentarisation des Hmongs et que ces derniers sont aptes à s'adapter à la vie moderne. La méthode d'enquête par entrevue sur la base d'un sondage employée sur le terrain nous a permis de découvrir les caractéristiques de développement durable autant socio-économique que politique dans la province de Vientiane avec application particulière aux Hmongs. Les résultats de l'enquête démontrent que les stratégies de sédentarisation sans relocalisation et avec relocalisation sur l'initiative soit personnelle soit gouvernementale ont fait leurs preuves. Des changements dans les modes de production et de vie ont non seulement permis une meilleure utilisation du sol, une augmentation de la production et une amélioration des conditions de vie mais aussi une meilleure préservation de l'écosystème.||Abstract : Sustainable development is an evolutionary process in which all ethnie groups live in harmony with a healthy environment. For approximately forty years, Laos has been subjected to many disruptions. Minority groups, like the Hmong, have felt the full impact of the numerous socio-political and economic changes that took place in the country. The Hmong, in particular, who live in mountainous regions and practice slash and burn agriculture, have suffered from economic and social inequality policies praticed by previous governments. The progressive transformation of their methods of land use, their mode of production and their migrant life style must clearly be understood before any attempt at a sedentary life style with a view to a sustainable development be undertaken. The underprivileged Hmong aspire to better living conditions comparable to those of people living in the plains. More precisely, the Hmong, who live in Lakhasipsong and Longsan in the province of Vientiane, adapt to their new conditions of social and economic transformation by fixing into place their mode of production and their lifestyle. We can state that the rural community development taking place allows an effective sédentarisation for the Hmong and, that they are able to adapt themselves to modem life. The survey method by interview and randown sampling on the ground permits us to discover elements of farming development within the socio-economic as well as political life in Vientiane province with a particular application to the Hmong. The survey results in showing that settling down strategies without relocation or with relocation on personal or governmental initiative are truly operational. Changes in the mode of production and life style have not only permitted a better land use, an increased production and a better life style but also, a better conservation of the environment.

Protección de los ocupantes de viviendas ante la insuficiente y heterogénea regulación del derecho de realojamiento en el Derecho español

El desarrollo de las ciudades comporta una integral transformación o renovación de zonas o barrios degradados, envejecidos e inadaptados a los servicios y estructuras requeridos por las actividades económicas y sociales actuales. Estas actuaciones de transformación y regeneración exigen el derribo de aquellas edificaciones incompatibles con la ordenaciónurbanística de nueva implantación, lo que conduce al desalojo y reubicación de sus ocupantes, de comprensible complejidad por las graves consecuencias que de ello se derivan cuando se trata de viviendas habitadas.

Economic Development of Urban Areas

In this dissertation I study the development of urban areas. At the aggregate level I investigate how they may be affected by climate change policies and by being designated the seat of governmental power. At the household level I study with coauthors how microfinance could improve the health of urban residents. In Chapter 1, I investigate how local employment may be affected by electricity price increases, which is a likely consequence of climate change policies. I outline how previous studies that find large, negative effects may be biased. To overcome these biases I develop a novel estimation strategy that blends border-pair regressions with the synthetic control methodology. I show the conditions for consistent estimation. Using this estimator, I find no effect of contemporaneous price changes on employment. Consistent with the longer time-frame for manufacturing decisions, I do find evidence for negative effects from perceived permanent price shocks. These estimates are much smaller than previous research has found. National capital cities are often substantially larger than other cities in their countries. In Chapter 2, I investigate whether there is a causal effect from being a capital by studying the 1960 relocation of the Brazilian capital from Rio de Janeiro to Brasília. Using a synthetic controls strategy I find that losing the capital had no significant effects on Rio de Janeiro in terms of population, employment, or gross domestic product (GDP). I find that Brasília experienced large and significant increases in population, employment, and GDP. I find evidence of large spillovers from the public to the private sector. Chapter 3 investigates how microfinance could increase the uptake of costly health goods. We study the effect of time payments (micro-loans or micro-savings) on willingness-to-pay (WTP) for a water filter among households in the slums of Dhaka, Bangladesh. We find that time payments significantly increase WTP: compared to a lump-sum up-front purchase, median WTP increases 83% with a six-month loan and 115% with a 12-month loan. We find that households are quite patient with respect to consumption of health inputs. We find evidence for the presence of credit and savings constraints.

Spatial multicriteria decision analysis to potential beekeeping assessment. Case study: Montesinho Natural Park (Portugal)

The Multicriteria decision analysis is a tool to support decision-making in the identification of areas with the utmost beekeeping potential. This paper design a GIS multicriteria approach to assess the beekeeping potential. The development of a conceptual model structure requires the participation of stakeholders and experts in that process. The spatial Multicriteria Decision Analysis (MCDA) allowed defining the potential beekeeping map. The resulting maps can be used by the beekeepers associations to easily select the more suitable areas for the apiaries location or relocation and avoid prohibited areas by legal requirements.

Der Anti-Bias-Ansatz als Methode politischer Erwachsenenbildung

Vorurteile, Macht und Diskriminierung sind die zentralen Themen des Anti-Bias-Ansatzes, der Diskriminierung auf zwischenmenschlicher, struktureller und gesellschaftlich-kultureller Ebene berücksichtigt. Die eigene Verwobenheit in Machtverhältnisse und damit verbundene Erfahrungen von Diskriminierung und Privilegierung sind dabei der Ausgangspunkt des Lernens. Vision ist eine vorurteilsbewusste, diskriminierungskritische und machtsensible Gesellschaft. Der vorliegende Beitrag stellt den Anti-Bias-Ansatz als Methode politischer Erwachsenenbildung vor. Hierfür werden die (Macht-)Mechanismen der Entstehung, Verinnerlichung und Reproduktion von Vorurteilen und Diskriminierung beleuchtet und wird die Intersektionalität (Überkreuzung) verschiedener Differenzlinien ausgemacht und aufgedeckt. Den Abschluss bildet ein Beispiel konkreter Umsetzung. (DIPF/Orig.)

Étude des mécanismes d’extraction lipidique par le peptide mélittine et la protéine BSP1

Les peptides et protéines extracteurs de lipides (PEL) se lient aux membranes lipidiques puis en extraient des lipides en formant de plus petits auto-assemblages, un phénomène qui peut aller jusqu'à la fragmentation des membranes. Dans la nature, cette extraction se produit sur une gamme de cellules et entraîne des conséquences variées, comme la modification de la composition de la membrane et la mort de la cellule. Cette thèse se penche sur l’extraction lipidique, ou fragmentation, induite par le peptide mélittine et la protéine Binder-of-SPerm 1 (BSP1) sur des membranes lipidiques modèles. Pour ce faire, des liposomes de différentes compositions sont préparés et incubés avec la mélittine ou la BSP1. L'association aux membranes est déterminée par la fluorescence intrinsèque des PEL, tandis que l'extraction est caractérisée par une plateforme analytique combinant des tests colorimétriques et des analyses en chromatographie en phase liquide et spectrométrie de masse (LCMS). La mélittine fait partie des peptides antimicrobiens cationiques, un groupe de PEL très répandu chez les organismes vivants. Ces peptides sont intéressants du point du vue médical étant donné leur mode d’action qui vise directement les lipides des membranes. Plusieurs de ceux-ci agissent sur les membranes des bactéries selon le mécanisme dit « en tapis », par lequel ils s’adsorbent à leur surface, forment des pores et ultimement causent leur fragmentation. Dans cette thèse, la mélittine est utilisée comme peptide modèle afin d’étudier le mécanisme par lequel les peptides antimicrobiens cationiques fragmentent les membranes. Les résultats montrent que la fragmentation des membranes de phosphatidylcholines (PC) est réduite par une déméthylation graduelle de leur groupement ammonium. L'analyse du matériel fragmenté révèle que les PC sont préférentiellement extraites des membranes, dû à un enrichissement local en PC autour de la mélittine à l'intérieur de la membrane. De plus, un analogue de la mélittine, dont la majorité des résidus cationiques sont neutralisés, est utilisé pour évaluer le rôle du caractère cationique de la mélittine native. La neutralisation augmente l'affinité du peptide pour les membranes neutres et anioniques, réduit la fragmentation des membranes neutres et augmente la fragmentation des membranes anioniques. Malgré les interactions électrostatiques entre le peptide cationique et les lipides anioniques, aucune spécificité lipidique n'est observée dans l'extraction. La BSP1 est la protéine la plus abondante du liquide séminal bovin et constitue un autre exemple de PEL naturel important. Elle se mélange aux spermatozoïdes lors de l’éjaculation et extrait des lipides de leur membrane, notamment le cholestérol et les phosphatidylcholines. Cette étape cruciale modifie la composition lipidique de la membrane du spermatozoïde, ce qui faciliterait par la suite la fécondation de l’ovule. Cependant, le contact prolongé de la protéine avec les spermatozoïdes endommagerait la semence. Cette thèse cherche donc à approfondir notre compréhension de ce délicat phénomène en étudiant le mécanisme moléculaire par lequel la protéine fragmente les membranes lipidiques. Les résultats des présents travaux permettent de proposer un mécanisme d’extraction lipidique en 3 étapes : 1) L'association à l’interface des membranes; 2) La relocalisation de l’interface vers le cœur lipidique; 3) La fragmentation des membranes. La BSP1 se lie directement à deux PC à l'interface; une quantité suffisante de PC dans les membranes est nécessaire pour permettre l'association et la fragmentation. Cette liaison spécifique ne mène généralement pas à une extraction lipidique sélective. L'impact des insaturations des chaînes lipidiques, de la présence de lysophosphatidylcholines, de phosphatidyléthanolamine, de cholestérol et de lipides anioniques est également évalué. Les présentes observations soulignent la complexe relation entre l'affinité d'un PEL pour une membrane et le niveau de fragmentation qu'il induit. L'importance de la relocalisation des PEL de l'interface vers le cœur hydrophobe des membranes pour permettre leur fragmentation est réitérée. Cette fragmentation semble s'accompagner d'une extraction lipidique préférentielle seulement lorsqu'une séparation de phase est induite au niveau de la membrane, nonobstant les interactions spécifiques PEL-lipide. Les prévalences des structures amphiphiles chez certains PEL, ainsi que de la fragmentation en auto-assemblages discoïdaux sont discutées. Finalement, le rôle des interactions électrostatiques entre les peptides antimicrobiens cationiques et les membranes bactériennes anioniques est nuancé : les résidus chargés diminueraient l'association des peptides aux membranes neutres suite à l'augmentation de leur énergie de solvatation.

Zika is not a reason for missing the Olympic Games in Rio de Janeiro: response to the open letter of Dr Attaran and colleagues to Dr Margaret Chan, Director - General, WHO, on the Zika threat to the Olympic and Paralympic Games

Attaran and colleagues in an open letter to WHO expressed their concern about the upcoming Olympic and Paralympic Games in Rio de Janeiro and the threat posed by the Zika epidemic (Attaran 2016). We agree that Zika virus is of great public health concern and much remains to be known about this disease. Care should be taken to reduce the risk of infection, especially to pregnant women. However, we argue that this is not sufficient reason for changing the original plans for the Games, in particular because of the time of the year when they will take place. The present article outlines several scientific results related to Zika and mosquito-borne infectious diseases dynamics that we believe ratify the current position of WHO in not endorsing the postponing or relocation of the 2016 Olympic and Paralympic Games (WHO 2016).
