Influence of characteristics of irrigation channels on the breeding bird community of a wetland zone in southeast of Spain

The “El Hondo Nature Park” is mainly composed of a series of irrigation channels and water reservoirs, subjected to various regimes of management as well as reed and vegetation control, thus creating a great variety of habitats and situations. To determine the influence of these habitats and management regimes on the local bird community, a set of characteristics of these channels and their surrounding area were analysed with a Correspondence Analysis (CA). The degree of reed development in channels and the presence in the surroundings of orchards and other reed formations were the most decisive factors to explain the probability of occurrence of reed birds and waterbirds, as well as bird species richness and abundance. Other bird species were not directly influenced by channel variables, but only by those of surrounding land uses.

Diet of Common Chiffchaffs Phylloscopus collybita wintering in a wetland in south-east Spain

The diet of Common Chiffchaffs Phylloscopus collybita wintering in a Mediterranean wetland (El Hondo Natural Park, SE Spain) was studied by analysing the gizzard content of 17 individuals that died accidentally when trapped for ringing. Prey availability was assessed via water-trap sampling over two winters. The bulk of the diet was composed of midges (Chironomidae), which were found in all the gizzards and represented approximately 95% of the prey. Brachycera flies were one of the most captured taxa in the water-traps but represented less than 0.5% of the total number of prey consumed. Compositional analysis revealed very strong prey selection, with Chiffchaffs selecting clumped and less mobile prey, such as chironomids, and avoiding abundant but fast-escaping prey, such as Brachycera.

Turismo y sostenibilidad en espacios naturales protegidos: la Carta Europea del Turismo Sostenible en la Zona Volcánica de la Garrotxa y el Plan de Desarrollo Sostenible en Cabo de Gata-Níjar

The impact of global warming on the tropical Pacific Ocean and El Niño

The El Niño–Southern Oscillation (ENSO) is a naturally occurring fluctuation that originates in the tropical Pacific region and affects ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide. Under the influence of global warming, the mean climate of the Pacific region will probably undergo significant changes. The tropical easterly trade winds are expected to weaken; surface ocean temperatures are expected to warm fastest near the equator and more slowly farther away; the equatorial thermocline that marks the transition between the wind-mixed upper ocean and deeper layers is expected to shoal; and the temperature gradients across the thermocline are expected to become steeper. Year-to-year ENSO variability is controlled by a delicate balance of amplifying and damping feedbacks, and one or more of the physical processes that are responsible for determining the characteristics of ENSO will probably be modified by climate change. Therefore, despite considerable progress in our understanding of the impact of climate change on many of the processes that contribute to El Niño variability, it is not yet possible to say whether ENSO activity will be enhanced or damped, or if the frequency of events will change.

Community involvement in urban nature conservation : case studies of the Urban Wildlife Group 1980-85

The effectiveness of the strategies employed by the Urban Wildlife Group (a voluntary conservation organisation) to provide and manage three urban nature parks has been evaluated, using a multiple methods methodology. Where the level of community interest and commitment to a project is high, the utilisation of the community nature park strategy (to maximise benefits to UWG and the community) is warranted. Where the level of interest and commitment of the local community is low, a strategy designed to encourage limited involvement of the community is most effective and efficient. The campaign strategy, whereby the community and UWG take direct action to oppose a threat of undesirable development on a nature park, is assessed to be a sub-strategy, rather than a strategy in its own right. Questionnaire surveys and observations studies have revealed that urban people appreciate and indeed demand access to nature parks in urban areas, which have similar amenity value to that provided by countryside recreation sites. Urban nature parks are valued for their natural character, natural features (trees, wild flowers) peace and quiet, wildlife and openness. People use these sites for a mixture of informal and mainly passive activities, such as walking and dog walking. They appear to be of particular value to children for physical and imaginative play. The exact input of time and resources that UWG has committed to the projects has depended on the level of input of the local authority. The evidence indicates that the necessary technical expertise needed to produce and manage urban nature parks, using a user-oriented approach is not adequately provided by local authorities. The methods used in this research are presented as an `evaluation kit' that may be used by practitioners and researchers to evaluate the effectiveness of a wide range of different open spaces and the strategies employed to provide and manage them.

Network Dynamics in Natural Resource Governance: A Case Study of Swiss Landscape Management

Structural characteristics of social networks have been recognized as important factors of effective natural resource governance. However, network analyses of natural resource governance most often remain static, even though governance is an inherently dynamic process. In this article, we investigate the evolution of a social network of organizational actors involved in the governance of natural resources in a regional nature park project in Switzerland. We ask how the maturation of a governance network affects bonding social capital and centralization in the network. Applying separable temporal exponential random graph modeling (STERGM), we test two hypotheses based on the risk hypothesis by Berardo and Scholz (2010) in a longitudinal setting. Results show that network dynamics clearly follow the expected trend toward generating bonding social capital but do not imply a shift toward less hierarchical and more decentralized structures over time. We investigate how these structural processes may contribute to network effectiveness over time.

Aprendizagem das ciências em espaços não-formais: visita de estudo na rota das energias renováveis

Nos programas actuais defende-se um ensino contextualizado numa perspectiva CTSA - Ciência, Tecnologia, Sociedade e Ambiente, e a diversificação de estratégias e actividades é recomendada. Numa perspectiva construtivista, a aprendizagem fora da sala de aula, aprendizagem em espaços não-formais - as visitas de estudo - são consideradas como uma das estratégias com elevado potencial pedagógico. No presente estudo foram realizadas e avaliadas duas visitas de estudo no âmbito da disciplina de Física e Química do 10° ano de escolaridade, tendo a primeira sido feita como estudo-piloto ao Centro de Ciência Viva de Constância e uma segunda como estudo principal, Na Rota das Energias Renováveis, à Barragem do Alqueva, Central Solar Fotovoltaica da Amareleja, Parque de Natureza de Noudar e Herdade do Esporão. Realizou-se uma pré-visita aos locais a visitar, estabeleceram-se contactos privilegiados com as instituições visitadas, preparam-se materiais didácticos, um Roteiro e um Guia de Campo para cada local visitado, foram elaborados e apresentados aos alunos questionários sobre o seu grau de satisfação com as visitas e realizaram-se ainda entrevistas em grupo com alguns alunos para recolher as suas impressões. Os alunos realizaram trabalhos de divulgação da visita tendo sido disponibilizada, no "site" da escola, informação detalhada sobre a visita. Neste estudo analisou-se em que medida uma aprendizagem contextualizada num espaço não-formal foi promotora de um envolvimento produtivo dos alunos. As aprendizagens realizadas situaram-se no domínio cognitivo, social ou atitudinal e os materiais didácticos, como o Guia de Campo tiveram um papel relevante para essas aprendizagens. A motivação dos alunos para a disciplina melhorou durante e após a visita. A colaboração com as instituições visitadas mostrou-se importante no estabelecimento de uma interface entre o espaço formal e o não-formal. A realização de visitas de estudo é uma componente importante dos curricula e deve ser encarada com naturalidade a sua realização frequente, como parte de uma estratégia para motivar os alunos para a disciplina e aumentar a sua capacidade de aprender os conteúdos. ABSTRACT: Nowadays programs defend teaching model that follows a perspective based in Science, Technology, Society and Environment, with special focus in the diversification of strategies. Outside of classroom teaching, in non-formal spaces, as in field trips, is considered one of the strategies with the highest pedagogic potential. ln this study, two field trips were made based on the Physics and Chemistry program for the 1Oth grade, with the first one as the pilot visit to Centro de Ciência Viva de Constância, and the second one as the main study, ln the Path of Renewable Energies, to Alqueva’s dam, Amareleja's Solar Photovoltaic Center, Noudar's Nature Park and Herdade do Esporão. A pre-visit was made for each one of the places to visit, contacts were made, materials were created, an itinerary and a Field Guide for both field trips, satisfaction questionaries were made to the students and the teacher also interviewed some students for appreciations about the visit. The students created posters about the field trip, and information was also showed in the school website. With this study, the benefits of a contextualized learning in a non-formal space were demonstrated. These acquisitions of knowledge were in various domains, such as cognition, social behavior and the didactic materials had a relevant role in these acquirements. Moreover, the students' motivation for the subject in question improved significantly during and after the field trip. The cooperation with the visited institutions revealed to be important in the establishment of an interface between the formal and the non-formal spaces. Making field trips is an important component in the curricula and should be encouraged and seen as a natural part of a strategy of motivation of the students for a certain subject, increasing its ability to learn matters.

ECO Sensaciones. Ecosistema del humedal Tibabúyes: valoración cultural para el patrimonio natural.

Esta propuesta tiene como objetivo central, diseñar un proyecto de gestión que sensibilice a la comunidad de la Ciudadela Colsubsidio frente al humedal Tibabúyes, promoviendo la valoración y sostenibilidad de este ecosistema, el más grande de la ciudad, vital para la preservación del ciclo hídrico. El proyecto contempla el desarrollo de estrategias que estimulen el sistema sensorial de la comunidad para así, generar transformaciones en los procesos de interacción que existen en la actualidad y hacer viable su sostenibilidad. Eco Sensaciones, es una metáfora que corresponde al resultado de una serie de estímulos sobre el sistema sensorial y que para el caso del proyecto, alude a las estrategias que se desarrollarán desde las emociones, pensadas desde el concepto de la Ecosofía, el cual hace referencia a un principio filosófico que plantea la necesidad de transformar los procesos de interacción humana con la naturaleza, para así activar y motivar la apropiación de la comunidad por el ecosistema. Contempla actividades centrales, como el desarrollo de una réplica del humedal “Tibabúyes portátil” y de recorridos por el ecosistema “Tibabúyes silencioso”, actividades que serán evaluadas en todas sus fases.
