On the Occurrence of Metadiaptomus chevreuxi (Calanoida, Diaptomidae, Paradiaptominae) in the Iberian Peninsula, With Notes on the Ecology and Distri…
2020
Temporary ponds are one of the most peculiar ecosystems in the world, being characterized by an extraordinarily rich crustacean fauna, with a high degree of endemism. Among them, diaptomid copepods are among the most biogeographically interesting taxa. However, the present knowledge on diaptomid distribution is still far from being exhaustive, even in the relatively well-studied western European countries. In this study, we report the first record of the diaptomid calanoid copepod Metadiaptomus chevreuxi for the Iberian Peninsula, where it was collected in five temporary ponds in Andalusia (Spain). The characteristics of the new sites are described, the literature dealing with the European …
The future of temporary wetlands in drylands under global change
2021
The Andalusian International University held a workshop entitled Temporary wetlands’ future in drylands under the projected global change scenario in March 2020 in Baeza, Spain, with 26 participants from 10 countries. The workshop objectives were to promote international cooperation and scientific exchange on the conservation and protection of temporary wetlands. The participants highlighted the extreme conditions that temporary and permanent wetlands, ponds, and shallow lakes are currently facing and predicted a dismal future for these systems due to climate change. To foster a holistic view of these ecosystems, the workshop included wetland watersheds. It was concluded that the main threa…

El tratamiento de los bienes y servicios que aporta la biodiversidad en manuales de los educación secundaria española: un estudio epistemológico.
2016
Este trabajo estudia el tratamiento del concepto de servicios ecosistémicos en libros de texto de la educación secundaria obligatoria (ESO) y bachillerato de España. Con el objetivo de definir su marco conceptual se recopilaron publicaciones científicas de la 'comunidad de expertos', que actúa de referente epistemológico en el proceso de transposición didáctica. El concepto de servicios ecosistémicos estuvo presente sólo en el 10 % de los manuales analizados (de un total de 50); sin embargo, en la mayoría de ellos se mencionó algún bien o servicio (sobre todo en libros de ciencias de la tierra y medioambientales). Estos resultados se relacionan con la ausencia de la conceptualización en el …
Situació actual del concepte de biodiversitat en l'educació obligatòria: revisió bibliogràfica
2013
L’educació a les escoles és fonamental per garantir la transmissió de coneixements que consciencien la població sobre la importància de la biodiversitat per tal de formar ciutadans respectuosos amb el medi. El principal objectiu d’aquest treball és analitzar la situació de l’ensenyament del concepte de biodiversitat en l’educació obligatòria. L’anàlisi es divideix en dues parts, en la primera, es realitza un estudi de l’art que ens mostra els temes de major interés en les investigacions relacionades amb l’ensenyament de la biodiversitat. En la segona part, s’agrupen les investigacions seleccionades i es classifiquen segons la temàtica de què tracten. Finalment, es presenta una taula amb els…
The bryophyte flora of the city of Valencia (Eastern Spain)
2021
Bryophytes constitute an important part of the unmanaged plant diversity of urban areas, however, it is generally overlooked and poorly understood. In this study, we investigate the urban bryoflora of Valencia, the third most important Spanish city. A total of 1,178 bryophyte samples from 94 sampling sites were identified rendering 102 taxa, 96 mosses and 6 liverworts. Despite the high overall taxon richness, the number of taxa per locality was rather low, 12.53±8.06. The sites that harbored the highest taxon richness were those with a variety of natural, old and relatively unmanaged substrates such as the Botanical Garden, Viveros Garden and the Turia River Garden. The high species richnes…
INSTITUT CAVANILLES DE BIODIVERSITAT I BIOLOGIA EVOLUTIVA
2005
L'Institut Cavanilles de la Universitat de València es dedica a l'estudi de la biodiversitat i la biologia evolutiva amb un enfocament integrador i pluridisciplinar. El punt més fort de l'Institut està en la seua capacitat per abordar pràcticament qualsevol qüestió relativa a la biodiversitat des de múltiples facetes, estudiant des de la morfologia fins al comportament, des de la variació genètica molecular fins a la quantitativa, i integrant experts en àrees complementàries.
Living on the edge: assessing the extinction risk of critically endangered Bonelli’s eagle in Italy
2012
Background: The population of Bonelli’s eagle (Aquila fasciata) has declined drastically throughout its European range due to habitat degradation and unnatural elevated mortality. There are less than 1500 breeding pairs accounted for in Europe, and the species is currently catalogued as Critically Endangered in Italy, where the 22 territories of Sicily, represent nearly 95% of the entire Italian population. However, despite national and European conservation concerns, the species currently lacks a specific conservation plan, and no previous attempts to estimate the risk of extinction have been made. Methodology/Principal Findings: We incorporated the most updated demographic information ava…
Saving the pharmacy of the sea: How does global change affect species with bioactive potential in the Mediterranean?
2020
Several marine species in the Mediterranean produce molecules with bioactive potential that could be used to develop new drugs (antibiotics, antifungals, antivirals, and antitumourals). Different human activities such as pollution, marine recreation, and fishing, as well as climate change, threaten and even endanger some of these species. These vulnerable species with bioactive potential must be protected, especially in marine reserves, not only because they are valuable components of marine ecosystems, but also because they are a potential source of molecules with pharmacological properties that are currently being researched for the creation of new drugs.
