Ecological correlates of Golden Eagle Aquila chrysaetos breeding occurrence in Sardinia

2020

Capsule Golden Eagles Aquila chrysaetos in Sardinia are clustered across the main mountain ranges of the island, with a preference for undisturbed and homogeneous inland habitats. Aims To analyse habitat preferences of the Golden Eagle in Sardinia, Italy, at the landscape and home range spatial scales. Methods Landscape scale habitat preferences were analysed using the 10 × 10 km Universal Transverse Mercator grid and the home range scale was based on the spatial distribution of breeding territories. Generalized linear models were fitted with three different sets of environmental predictors (topographic, bioclimatic and land use variables) to analyse the spatial distribution of Golden Eagle…

New populations of the threatened fern Equisetum moorei Newman in the Valencian Community (Spain)

2020

Se aportan nuevas citas del helecho amenazado Equisetum moorei en la Comunidad Valenciana, donde solo se conocían previamente seis localidades con presencia actual de la especie. Una de las nuevas poblaciones am­plía notablemente el área de distribución conocida en esta región, ya que la mayor parte de las localidades conocidas se concentraban en el macizo del Peñagolosa (provincia de Castellón). Se describen las características ecológicas y demográficas de las nuevas localidades en el contexto de las poblaciones previamente conocidas en la región valenciana.

Testing macroecological abundance patterns:the relationship between local abundance and range size, range position and climatic suitability among Eur…

2020

Aim A fundamental question in macroecology centres around understanding the relationship between species' local abundance and their distribution in geographical and climatic space (i.e. the multi-dimensional climatic space or climatic niche). Here, we tested three macroecological hypotheses that link local abundance to the following range properties: (a) the abundance-range size relationship, (b) the abundance-range centre relationship and (c) the abundance-suitability relationship. Location Europe. Taxon Vascular plants. Methods Distribution range maps were extracted from the Chorological Database Halle to derive information on the range and niche sizes of 517 European vascular plant speci…

Factores que influyen en la colonización vegetal y la revegetación de taludes de carreteras en ambiente mediterráneo.

2007

Actualmente la construcción de carreteras produce un grave impacto ambiental, produciéndose extensas áreas sin vegetación en forma de taludes. En ambientes mediterráneos áridos o semiáridos la restauración de la cubierta vegetal después de las obras resulta muy complicada debido a diversos factores. Tanto propios de los taludes de carreteras como debidos a las especies que se utilizan en las revegetaciones.En esta tesis doctoral se pretende estudiar la importancia relativa de diversos factores que modulan la colonización vegetal y la revegetación en taludes de carreteras. Se ha planteado que en zonas alteradas la principal limitación para la colonización es la falta semillas, pero la aplica…

Política nacional de agroecología y producción orgánica: productores de café en el sur de Minas Gerais: Brasil.

2017

Resumen El crecimiento del consumo de café robusta (originario de Vietnam) en España, las estrategias del mercado de cafés especiales procedentes de Etiopía, Panamá y Guatemala para ampliar sus márgenes de mercado en España y la evidente reducción de la participación del café brasileño en el mercado español me han motivado a hacer el estudio sobre evaluación de la Política Nacional de Agroecología y Agricultura Orgánica- PLANAPO en el sector de café. La PLANAPO es una política pública del gobierno brasileño creada para extender e implementar acciones para el desarrollo rural sostenible. En el trabajo de investigación, el objetivo general ha sido analizar los efectos globales y de largo plaz…

EUNIS Habitat Classification: Expert system, characteristic species combinations and distribution maps of European habitats

2020

Aim The EUNIS Habitat Classification is a widely used reference framework for European habitat types (habitats), but it lacks formal definitions of individual habitats that would enable their unequivocal identification. Our goal was to develop a tool for assigning vegetation-plot records to the habitats of the EUNIS system, use it to classify a European vegetation-plot database, and compile statistically-derived characteristic species combinations and distribution maps for these habitats. Location Europe. Methods We developed the classification expert system EUNIS-ESy, which contains definitions of individual EUNIS habitats based on their species composition and geographic location. Each ha…
