54 p, 895.6 KB Spatial variability in the soil macroinvertebrate food web of an agroecosystem : a stable isotope analysis / Hernández-Castellano, Carlos ; Piñol, Josep, dir. ; Centre de Recerca Ecològica i d'Aplicacions Forestals
Although trophic structure and feeding preferences of soil macroinvertebrates can change among habitats, the extent to which food web structure varies within ecosystems is unknown. In this work we aimed to assess changes in food web structure in an agroecosystem using an experiment setting in which plant and macroinvertebrate community composition and stable isotopes (δ13C and δ15N) of soil, plants and macroinvertebrates were analyzed at increasing distances from trees within a citrus grove and in an adjacent abandoned field.

38 p, 5.5 MB Seasonal variation in floral resources and their potential consequences on plant-pollinator network structure / Lonighi Iturbide, Arturo ; Bosch, Jordi, 1961- , dir. (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Rodrigo Domínguez, Anselm (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Arnan, Xavier, dir. (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Universitat Autònoma de Barcelona. Facultat de Biociències
Implications of seasonal variation of floral resources in the Mediterranean on the network structure of a plant-pollinator community, regarding to changes in the degree of specialization of the network due to competition for resources.
Implicacions de la variació estacional dels recursos florals al Mediterrani sobre l'estructura de xarxa d'una comunitat planta-pol·linizador, en relació amb els canvis en el grau d'especialització de la xarxa a causa de la competència pels recursos.

22 p, 2.0 MB Inter-annual variation in the plant-pollinator network of a rupicolous plant community / Izquierdo Ferreiro, Iago ; Bosch Gras, Jordi ; Navarro Echeverría, Luis ; Universitat Autònoma de Barcelona. Facultat de Biociències
Pollination networks are a representation of the interactions between the plant and pollinator communities in a particular location. Communities change in composition and structure from year to year, and therefore their interactions. [...]
Les xarxes de pol·linització representen les interaccions entre la planta i les comunitats de pol·linitzadors en un lloc concret. Les comunitats canvien de composició i estructura d'un any a altre, i per tant les seves interaccions. [...]

38 p, 948.2 KB Modelling the dynamics of oak-pine Mediterranean forests in a climate change scenario / Bassols Garcia, Jordi ; Martínez Vilalta, Jordi, 1975-, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; García-Valdés, Raúl, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Universitat Autònoma de Barcelona. Facultat de Biociències
Climate change is affecting forest communities all around the globe. Increased aridity due to warmer temperatures is causing widespread cases of drought-induced forest dieback, thus altering forest dynamics. [...]
El canvi climàtic està afectant les comunitats forestals a nivell global. L'increment de l'aridesa causat per les altes temperatures està provocant un augment de la mortalitat, alterant així les dinàmiques dels boscos. [...]

42 p, 2.5 MB Butterfly diversity in the Montseny Mountains : patterns and processes / Carper, Lisa Gale ; Carnicer i Cols, Jofre ; Stefanescu, Constantí ; Universitat Autònoma de Barcelona. Facultat de Biociències
Aim: To describe spatial patterns of Mediterranean butterfly species richness by functional groups, analyze their main landscape and climatic drivers, test the existence of extinction debt effects, and predict past species richness distributions using past climatic and landscape data. [...]

33 p, 3.5 MB Comparative phylogeography of chloroplast and nuclear DNA markers reveals ancient and present hybridization in the Mediterranean Helichrysum pendulum complex (Compositae) / Herrando-Moraira, Sonia ; Galbany-Casals, Mercè (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Vilatersana Lluch, Roser ; Universitat Autònoma de Barcelona. Facultat de Biociències
The geological and climatic history of the Mediterranean basin over the last 6 million years has been determinant in shaping current geographic distribution of genetic variation in organisms. Phylogeographical approaches are considered one of most useful analysis for unraveling the evolutionary history of species. [...]

37 p, 1.2 MB Relationship between floral colour and pollinator composition in four plant communities / Reverté Saiz, Sara ; Bosch, Jordi, 1961-, dir. (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Retana Alumbreros, Javier (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Universitat Autònoma de Barcelona. Facultat de Biociències
Pollinators use a variety of floral cues to locate resources, but the relative importance of these different cues on pollinator foraging decisions is unclear. However, floral colour is undoubtedly one of the most important, as evidenced in previous works revealing the importance of floral colour on pollinator choices and determining flower visitor composition.

31 p, 767.0 KB Effects of past landscape and habitat changes in plant invasion provide evidence of an invasion credit / Clotet Fons, Maria ; Pino i Vilalta, Joan (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Basnou, Corina ; Universitat Autònoma de Barcelona. Facultat de Biociències
Habitats differ in the invasion degree due to habitat properties and current spatial context. Historical context effects (i. e. land use change legacy) have been little studied and can be modulated by the invasion credit (the delayed increase in habitat invasion after changes in the land use). [...]

27 p, 868.5 KB Ecology predicts life history evolution in birds / Unzeta Lloret, Mar ; Sol, Daniel, tut. (Centre de Recerca Ecològica i d'Aplicacions Forestals) ; Universitat Autònoma de Barcelona. Facultat de Biociències
Although a number of studies describe current evolutionary patterns concerning life-history evolution, how historical changes in the way organisms interact with their environment have shaped life-history evolution still remains unresolved. [...]

26 p, 977.5 KB Disentangling the probability of large fire occurrence in Mediterranean forests : management guidelides from a multiscale approach / Lasheras Álvarez, Laura ; Brotons, Lluís ; Gil-Tena, A ; Duane Bernedo, Andrea ; Universitat Autònoma de Barcelona. Facultat de Biociències
Fire is one of the main disturbances in Mediterranenan ecosystems. In the recent decades, in Catalonia (NE Spain), the number of fires has decreased while burnt area has increased. This is related to changes in land use, climate and fire suppression policies which influenced horizontal and vertical fuel continuity. [...]
