The present work aimed to reconstruct rockrose (Cistus ladanifer L.) historical and future spatial distribution, a typically Mediterranean species with abundant occurrence in North Africa, Iberian Peninsula, and Southern France. The R ensemble modeling approach was made using the biomod2 package to assess changes in the spatial distribution of the species in the Last Interglacial (LIG), the Last Glacial Maximum (LGM), and the Middle Holocene (MH), in the present, and in the future (for the years 2050 and 2070), considering two Representative Concentration Pathways (RCP 4.5 and RCP 8.5). The current species potential distribution was modeled using 2,833 occurrences, six bioclimatic variables, and four algorithms, Generalized Linear Model (GLM), MaxEnt, Multivariate Adaptive Regression Splines (MARS), and Artificial Neural Networks (ANN). ...

This protection could be granted only to the varieties that comply with the DUS test. That is, the new variety must be distinct (D) from any other existing variety, and also sufficiently uniform (U) and stable (S). Liquidambar styraciflua L. is an ornamental tree species with a high economic value. Several varieties of this plant have been obtained. Nevertheless, the Guidelines for the conduct of the DUS test in this species are not defined yet. In this paper, we have evaluated a set of Characteristics (covering variation in size, shape and colour of leaves and branches) in sixteen L. styraciflua varieties in order to select those traits that better fulfil the DUS test requirements. For this purpose, Classification And Regression Trees (CART) [1] have been used. In comparison with ...

Os autores coordinaron as actividades de presentacion deste proxecto, co afan de resumir un sentimento compartido.

We conducted a pilot-scale study to assess the potential conversion of A. dealbata biomass by vermicomposting via the earthworm Eisenia andrei. The flowering aerial A. dealbata biomass was shredded and placed in a vermireactor under greenhouse conditions for 56 days. The vermicomposted material was sampled every two weeks to analyse its biological and chemical parameters. The phytotoxicity of the fresh A. dealbata material and vermicompost was assessed via an ecotoxicological test with Lepidium sativum seeds. The activity of the earthworms caused strong modifications of the properties of the processed material: the electric conductivity, basal respiration, and organic matter content were reduced, whereas the concentrations of other elements such as N, P, or Zn increased. The earthworm biomass incr...

Roteiro 1: “Árbores de dous grandes grupos: ximnospermas e anxiospermas”. As plantas produtoras de sementes divídense en dous grandes grupos: as ximnospermas (piñeiros, alciprestes, xinkgos, cicas, etc.) e as anxiospermas (a maioría das plantas con flor, tanto silvestres como cultivadas). Durante este roteiro aprenderemos a diferenciar estes dous grandes grupos, e coñeceremos varias especies representativas de cada un deles. Roteiro 2- “Unha volta ao mundo coas árbores”. Neste roteiro desenvolveremos unha viaxe no espazo e no tempo, acompañando a comerciantes e descubridores, para coñecer como o contacto con rexións e culturas afastadas serviron para que os nosos xardíns se fosen enriquecendo con plantas traídas de diferentes continentes. Ademais, empregaremos os xardíns do Campus Sur da USC como unha xanela desde a que podemos albiscar, ao tempo que paseamos, unha parte da diversidade vexetal que existe no mundo. Roteiro 3. “Árbores con proveito”. Alén do valor intrínseco que posúe a biodiversidade, as árbores e arbustos supuxeron xa desde hai milleiros de anos unha fonte de recursos: madeira, alimento, medicina..., para o ser humano. Mais certas especies tamén foron orixe de lendas e tradicións, de xeito que para moitas culturas as árbores tiveron o papel de protectoras espirituais ou mesmo de sustentadoras do universo. Neste roteiro coñeceremos moitos segredos das árbores! Roteiro 4 “AS CORES E AS FORMAS DAS ÁRBORES” As copas, follas, flores, codias... de árbores e arbustos poden adquirir unha gran diversidade de formas e cores, como se pode ver se por exemplo, se compara un magnolio cun cedro. Centraremos este roteiro no recoñecemento desta variabilidade, ao tempo que aprendemos cousas novas das plantas.

(=Alyssum serpyllifolium Desf.) occurs in the Iberian Peninsula and adjacent areas on a variety of soils including both limestone and serpentine (ultramafic) substrates. Populations endemic to serpentine are known to hyperaccumulate nickel, and on account of this remarkable phenotype have, at times, been proposed for recognition as taxonomically distinct subspecies or even species. It remains unclear, however, to what extent variation in nickel hyperaccumulation within this taxon merely reflects differences in the substrate, or whether the different populations show local adaptation to their particular habitats. To help clarify the physiological basis of variation in nickel hyperaccumulation among these populations, 3 serpentine accessions and 3 limestone accessions were cultivated hydroponically under common-garden conditions incorporating a range of Ni concentrations, along with 2 closely related non-accumulator species, Clypeola j...
