Seseli farrenyi (Apiaceae) is an extremely narrow endemic plant, which is considered as one of the species of most conservation concern in Catalonia (NW Mediterranean Basin). Given the accelerated fragmentation and reduction of population size (of over 90%), the environmental agency of Catalonia is currently preparing a recovery plan that includes...

RESUMEN: Dentro del proceso de enseñanza-aprendizaje cada vez son más necesarias habilidades de edición de libros de texto electrónicos realizados por los propios estudiantes y tutorizados por el profesor. En este marco se describe el diseño y se aporta el análisis de los resultados de una experiencia colaborativa llevada a cabo con 228 estudiante...
Article
Protection and management of closely related endangered species and subspecies at a very narrow regional scale is the origin of multiple dysfunctional conservation decisions. These include artificially increased IUCN risk assessment categories and derived consequences: poor effectiveness in allocating public and private funds or repeat of unnecessa...

D’ençà la implantació de l’EEES, els sistemes d’avaluació han esdevingut clau en el procés d’ensenyament-aprenentatge universitari, fins el punt que són determinants en com l'alumnat aprèn-estudia, alhora que tenen una gran influència en què i com s'ensenya. Presentem una primera anàlisi comparativa dels sistemes avaluatius de les 80 assignatures t...

The chromosome database of the wild vascular flora of the Catalan Countries (CromoCat) contains a total of 57.7012 records, documented in 8157 bibliographic references. It includes 3135 chromosome number reports from the territories covered by the Flora dels Països Catalans (Bolòs et al., 2005), representing 27,7% of the total number of taxa (speci...

Low levels of genetic diversity in endemic species are generally attributable to the small size of their populations. This lack of genetic variability will, predictably, be more evident in those species that occur in only one or a very few localities with a total population consisting of a few dozen individuals, or sometimes fewer. López-Pujol et a...

We used allozyme electrophoresis to survey genetic diversity of Agrostis barceloi L.Sáez & Rosselló, an extremely narrow endemic species from the island of Majorca (Balearic Islands, Western Mediterranean Basin). This species is a tetraploid with a single natural population of less than 100 individuals. All analyzed individuals of A. barceloi showe...

Stachys maritima is a species typical of the coastal dunes with a wide distribution within the Mediterranean Basin. During the last century, this species was subjected to severe habitat fragmentation, mainly as a consequence of tourism activities and urban pressures, with a decreasing of area up to 99% in the Iberian Peninsula and a remaining total...

Dichoropetalum schottii is a species that lives at low to medium altitudes in the southern European mountain ranges, from the Balkans (N Greece) to the Pyrenees. Its legal protection status is not homogeneous along its distribution range, as only some of its edge populations, in the Pyrenees, are protected. Here, by means of allozyme electrophoresi...

Silene sennenii is a narrow endemic species from the NE of the Iberian Peninsula. It is considered as EN (“Endangered”) according to the IUCN criteria and is under legal protection in Catalonia. In the present work we report an assay using three different approaches for surveying the genetic diversity in this rare, endangered campion: analysis of c...

Aquilegia paui is an extremely narrowly endemic species from the northeastern Iberian Peninsula. It is restricted to a few populations with a reduced number of individuals living in summit rock cliffs. It is studied and compared to the widespread Aquilegia vulgaris to assess differences in their breeding system and pollination ecology, expected by...
Article
Full-text available
The extremely rare Aquilegia paui (Ranunculaceae) was described in 1920 but was not found again until 1999, when it was discovered in the Parc Natural dels Ports in Tarragona Province, Spain. This species had been confused with the widespread A. vulgaris and consequently its taxonomic and conservation status had been misinterpreted. Based on the li...
Article
Sexual dimorphism can have implications in the reproductive biology of gynodioecious species, affecting sex fitness. We explored the effects of flower sex on pollination visitation rates and pollinator efficiency in terms of stigmatic pollen loads, as well as on quantitative and qualitative aspects of reproductive success in two populations of Thym...

L’endemisme empordanes Silene sennenii es una especie singular que es troba en perill d’extincio a causa, principalment, de la desaparicio progressiva del seu habitat. En els ultims anys, l’interes en la seva conservacio ha anat en augment, donant lloc a diversos estudis cientifics adrecats a coneixer-la millor i a proposar mesures i mecanismes per...

Seseli farrenyi es un endemismo estrictamente catalán, que cuenta con un número muy reducido de poblaciones en la franja litoral norte del cabo de Creus (Alt Empordà). La especie ha sido catalogada como “En Peligro” (EN) según los criterios de la UICN basándose en una serie de estudios realizados a finales de los años noventa, incluyendo censos y c...

Deu anys de seguiment demogràfic i genètic d’Stachys maritima a Catalunya (2001-2010). Implicacions per a un pla de recuperació.- Stachys maritima és una espècie característica de dunes litorals, amb una àmplia àrea de distribució a la Mediterrània. Malgrat això, la planta sembla estar en clara regressió. A Catalunya, s’ha observat un declivi signi...

L'any 2010 va iniciar-se com l'any internacional de la diversitat biològica, com a punt d'inflexió en el context del "Compte enrere 2010", amb l'objectiu de deturar la pèrdua de biodiversitat a escala mundial. Si bé s'han aconseguit progressos significatius, propiciats per l'efemèride, encara som lluny d'haver revertit la situació de manera satisfa...

Seseli farrenyi is a narrow endemic from Catalonia (Spain). Only a very limited number of populations of this species are known, located in the north coast of the Creus Cape (Alt Empordà). This species has been catalogued as “Endangered” (EN) according to the IUCN criteria, based on a series of studies performed in the late 1990s, which included ce...
