“…Recent phylogeographic studies have shown that the Iberian Central System has acted as an historical barrier to gene flow in the two species, separating different evolutionary groups north and south of this mountain range (Gutiérrez‐Rodríguez, Barbosa, & Martínez‐Solano, ,b). These groups would have experienced limited connectivity during the Last Glacial Maximum (21 ka), as glacial areas occupied lower altitudes around 1,350 m in the study area (Bullón, ). In contrast, vegetation dynamics in the Central System mountains have been constantly changing during the Holocene due to human activities (López‐Sáez et al., ).…”

Comparative landscape genetics studies can provide key information to implement cost-effective conservation measures favouring a broad set of taxa. These studies are scarce, particularly in Mediterranean areas, which include diverse but threatened biological communities. Here, we focus on Mediterranean wetlands in central Iberia and perform a multi-level, comparative study of two endemic pond-breeding amphibians, a salamander (Pleurodeles waltl) and a toad (Pelobates cultripes). We genotyped 411 salamanders from 20 populations and 306 toads from 16 populations at 18 and 16 microsatellite loci, respectively, and identified major factors associated with population connectivity through the analysis of three sets of variables potentially affecting gene flow at increasingly finer levels of spatial resolution. Topographic, land use/cover, and remotely sensed vegetation/moisture indices were used to derive optimized resistance surfaces for the two species. We found contrasting patterns of genetic structure, with stronger, finer scale genetic differentiation in Pleurodeles waltl, and notable differences in the role of fine-scale patterns of heterogeneity in vegetation cover and water content in shaping patterns of regional genetic structure in the two species. Overall, our results suggest a positive role of structural heterogeneity in population connectivity in pond-breeding amphibians, with habitat patches of Mediterranean scrubland and open oak woodlands ("dehesas") facilitating gene flow. Our study highlights the usefulness of remotely sensed continuous variables of land cover, vegetation and water content (e.g., NDVI, NDMI) in conservation-oriented studies aimed at identifying major drivers of population connectivity.

“…Sin embargo, debido a la morfología glaciar residual (Acaso, 2006;Bullón, 1997Bullón, , 2016 y a la evolución periglaciar (Palacios et al, 2004(Palacios et al, , 2012 que afecta a algunos sectores de las altas vertientes del área de estudio, los procesos de arroyada mixta nivo-pluvial generan, en la base de los circos y nichos de nivación, un incremento considerable de pequeñas incisiones y regueros como reflejan los altos valores de densidad de la disección en las altas laderas del macizo de Peñalara -en el sector central-o en el ámbito al norte de Flecha y área de los Pelados -en el tercio septentrional de la zona de estudio-, tal y como se aprecia en el mapa (Bullón, 1995;Palacios et al, 2012Palacios et al, , 2016. Mientras que en la mayor de la zona de estudio con valores similares evidencian un claro y marcado control tectónico, al concentrarse la escorrentía explotando la red de fracturas, lo cual disminuye la densidad de la disección, dado que de otra forma la dureza de los materiales -granitos y gneis-hace difícil el encajamiento.…”

The arid aeolian sedimentary systems in the Canary Islands have suffered notable environmental impacts. The transition from traditional land uses to other more recent uses has generated a series of environmental changes that are reflected both in the vegetation and in the aeolian sedimentary dynamics. The aim of this research is to reconstruct and analyze these processes and to know the response capacity of these ecosystems to anthropogenic alterations. The methodology used to make the historical reconstruction of land uses and their socio-environmental consequences combines historical and current sources under the framework of Historical ecology. The historical land uses have been analyzed and the environmental consequences on the studied systems have been evaluated. The main results show that the use of vegetation was decisive in the transformation of the systems between 1750 and 1960 for El Jable and Jandía; while, for El Médano, the extraction of aggregates and the creation of an aerodrome are responsible for the alteration of the sedimentary system. In all three systems, when land uses cease and the systems are protected, although there is a recovery, new environmental impacts also appear and the legacy of the existing ones is still notorious.
