The effect of vegetation structure on seasonal density of Sylvia warblers in the eastern Iberian Peninsula
2021
Vegetation characteristics determine seasonal habitat selection by Eurasian Blackcaps Sylvia atricapilla, Dartford Warblers Sylvia undata, and Sardinian Warblers Sylvia melanocephala, and changes i...
New Data on Orthotrichum gigantosporum Lewinsky (Orthotrichaceae, Bryophyta), a Widespread Northern Andean-Patagonian Endemic Moss
2021
The moss family Orthotrichaceae is still poorly known in the southern extreme of South America. This is especially true regarding the morphological variability, geographical distribution, and ecological affinities of the species restricted to the Andean-Patagonian area. These deficiencies are addressed for Orthotrichum gigantosporum Lewinsky, one of the least known and most interesting endemics of the area. After examining the rich collections made by our team in southern Chile and Argentina, we have found numerous new localities for the species. Orthotrichum gigantosporum has proven to be a widespread moss in the forests and scrublands of the northern sector of the Andean-Patagonian area. …

Diversity of Diatrypaceae species in three Spanish grapevine producing regions.
2015
The objective of this study was to identify species of Diatrypaceae associated with trunk diseases in three different Spanish grapevine producing regions: Albacete, Cádiz and Valencia provinces, located, respectively, in geographically distant areas of Central, South and Eastern Spain. Species identification of 71 isolates was performed using a combination of morphological characters and phylogenetic analyses based on the internal transcribed spacer regions of the rDNA (ITS) and the β-tubulin gene. Four species of Diatrypaceae were identified: Cryptovalsa ampelina was the predominant species (63.4%) followed by Eutypa lata (19.7%), Eutypella microtheca (4.2%), and Eutypella citricola (2.8%)…
Metabolites produced by agents of dieback of grapevine in Sicily: Lasiodiplodia mediterranea, Neofusicoccum parvum and N. vitifusiforme
2015
Botryosphaeria dieback was recently reported in West Sicilian vineyards. The disease complex was only associated with isolates of genus Lasiodiplodia in 2007 and together with Diplodia seriata, Neofusicoccum parvum and Neofusicoccum vitifusiforme, this latest reported for the first time on Vitis vinifera in Italy. Moreover, a representative isolate of each species was inoculated on green shoots and fulfilled Koch’s postulates, although the lengths of vascular discolourations were variable depending on the species. As well as the other GTD causal agents, the expression of foliar symptoms (pale colour along the margins and between veins) was also occasional in Sicily, it was hypothesized that…
Public and Private Economic Feasibility of Green Areas as a Passive Energy Measure: A Case Study in the Mediterranean City of Trapani in Southern Ita…
2022
Green infrastructure in urban environments provides a wide range of ecological, social, aesthetic, and health co-benefits. Urban plant covers in particular contribute to improved outdoor environmental conditions that, in turn, influence the energy behavior of buildings and their indoor thermo-hygrometric comfort performance. Within this context, this study illustrates a methodology aimed at verifying the economic feasibility of alternative types of green areas for public and private stakeholders, which are analyzed as passive energy measures. Therefore, our methodology integrates approaches from different disciplines and consists of a microclimatic analysis of different vegetation scenarios…
Urban Heat Island (UHI) and heat waves: what relations?
2018
With four years of measurements and alarge sample of stations, the MUSTARDijon network allows for a detailed characterization of the Urban HeatIsland (UHI), a warm season phenomenon. But UHI and maximum temperature values are out of phase at twodistinct time-scales. Seasonally, the maxima of UHI occur from May to July, i.e. before the annual peak oftemperature (July to August). At a daily time-scale, analysis of the two heat waves of July 2015 shows a lag of afew days between the peak of UHI and the heat wave. Two hypotheses are suggested to explain these lags:changes in radiative conditions and/or energy fluxes between the ground surface and the atmosphere.
Protocolo de germinación de Thelypteris palustris Schott (THELYPTERIDACEAE) y cultivo de planta adulta.
2015
El conocimiento de métodos para la propagación de los helechos, especialmente los acuáticos, hoy en día en el que el cambio climático, y en general el impacto que el ser humano tiene en los hábitats naturales, es un paso necesario para su conservación. Esta ficha aporta datos relevantes sobre la germinación de las esporas, el cultivo de gametofitos y la obtención de esporofitos de esta especie. Este trabajo se ha cofinanciado por la Generalitat Valenciana (Consellería de Agricultura, Medio Ambiente, Cambio Climático y Desarrollo Rural, Servicio de Biodiversidad) y la Universitat de València.
Protocolo de germinación de Asplenium marinum L. (ASPLENIACEAE) y cultivo de planta adulta. (Botanic asPPECTS Número 1.1)
2015
Conseguir un protocolo de propagación a partir de esporas, de un helecho considerado de gran rareza en nuestro territorio, contribuye al éxito en la conservación de sus poblaciones naturales.
Protocolo de germinación de esporas y caracterización del desarrollo de los gametofitos de Asplenium majoricum Litard. (ASPLENIACEAE)
2017
Los planes de conservación de flora amenazada incluyen acciones que requieren la conservación de esporas a largo plazo en bancos de germoplasma y la determinación de protocolos de germinación y cultivo de plántulas para la obtención de planta. En los helechos el estudio de la respuesta germinativa y desarrollo gametofítico es fundamental para tener éxito en las labores de propagación orientadas a los programas de refuerzo y reintroducción.
