42 p, 2.5 MB Butterfly diversity in the Montseny Mountains : patterns and processes / Carper, Lisa Gale ; Carnicer i Cols, Jofre ; Stefanescu, Constantí
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
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 Gras, Jordi, 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)
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
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, tutor (Centre de Recerca Ecològica i Aplicacions Forestals)
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, Assumpció ; Duane Bernedo, Andrea
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. [...]

42 p, 3.5 MB Drought-induced effects in coexisting Mediterranean shrubs in relation to species' bioclimatic niche / Sapés de Moreta, Gerard ; Lloret Maya, Francisco, dir. (Universitat Autònoma de Barcelona.Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Climate-induced drought is one of the principal factors altering plant community dynamics and composition as well as species' geographic distributions in the Mediterranean basin. The use of bioclimatic models that consider both bioclimatic conditions and species' geographic distributions to predict potential scenarios under these climatic conditions have recently become extensively developed. [...]

38 p, 1.3 MB Brain size and evolutionary diversification in birds / Sayol i Altarriba, Ferran ; Sol, Daniel, dir. (Centre de Recerca Ecològica i Aplicacions Forestals)
The role of behavior in evolution remains controversial, despite that some ideas are over 100 years old. Changes in behavior are generally believed to enhance evolution by exposing individuals to new selective pressures and by facilitating range expansions. [...]

39 p, 3.5 MB Invasive populations of Senecio pterophorus are neither more productive nor more plastic than the native populations / Colomer Ventura, Ferran ; Castells Caballé, Eva ; Martínez Vilalta, Jordi, 1975- (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
Successful plant invaders may have specific morphological and physiological traits that promote invasion in a new habitat. The Evolution of Increased Competitive Ability (EICA) hypothesis predicts that plants released from natural enemies in the introduced habitats are more competitive and perform better than plants from the native populations. [...]

27 p, 8.1 MB Response of fine root respiration to variations in biotic and abiotic factors in a mixed Mediterranean forest affected by drought-induced secondary succession / Pereira Blanco, Eva ; Lloret Maya, Francisco (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Curiel Yuste, Jorge ; Barba Ferrer, Josep
Understanding the factors controlling fine root respiration (FRR) at different temporal scales will help to improve our knowledge about the spatial and temporal variability of soil respiration (SR) and to improve future predictions of CO2 effluxes to the atmosphere. [...]
