          Resumen/AbstractNine-spined stickleback (Pungitius pungitius) has a circumpolar distribution, and can successfully persist in a bewildering array of habitats from coastal marine areas through large lakes or rives systems to small isolated ponds. By comparing pond populations (nine-spined stickleback is often the only fish species) to lake and marine populations (nine-spined stickleback is a member of a diverse fish community including predators and competitors), I could study how sticklebacks adapted to varying levels of predation and interspecific competition. In general, I found that a ‘pond ecomorph’ emerged in several geographically and genetically isolated ponds throughout Fennoscandia. Sticklebacks in ponds evolved into aggressive and bold giants with extended longevity, delayed maturation and reduced or lost body armour. These results suggest that in the absence of significant predation risk and interspecific competition, a phenotype superior in intraspecific competition is favoured. In my talk, I will first overview the basic patterns of population divergence in fitness-related traits and in their phenotypic plasticity, and then present the quantitative genetic and functional genomic background of some key morphological, life-history and behavioural traits.”

Hola a todas/os:
El VIERNES 1 de FEBRERO, a las 12h hay un seminarion de investigación en el salón de actos del Museo de Ciencias Naturales (C/José Gutiérrez Abascal 2, 28006-Madrid)
Título:SECASOL project: direct and indirect effects of climatic variability on soil microbial communities and soil C fluxes”
     Impartido por: Dr. Jorge Curiel Yuste, Ramón y Cajal Fellow, Museo Nacional de Ciencias Naturales (MNCN-CSIC)
          Resumen/Abstract:The aim of our talk will be to show an overview of the results obtained within the framework of SECASOL project. The central hypotheses of this project was that both direct effects (increasing summer droughts) and indirect effects (climate-change driven changes in forest structure and composition) of climate change in the Mediterranean basin would strongly affect microbial community ecology and functioning, and consequently affecting C cycles in these ecosystems. More in detail, activities within this project were: (1) To investigate possible effects of climate -change driven secondary succession on soil bacterial/fungal taxonomic composition as well as soil C dynamics in ecotonal forest. (2) To investigate possible effects of long-term droughts (10 years) on both structure and functioning (SOM decomposition) of soil microbial communities (3) To investigate the effects of secondary succession and drought on soil respiration and its different biological soil compartments (autotrophic, symbiotic and heterotrophic). We applied a very interdisciplinary approach for these purposes, combining state-of-the-art molecular methodologies (DNA pyrosequencing), 13C solid-state Nuclear Magnetic Resonance (CP-MAS 13C NMR) to investigate changes in SOM composition, different techniques to study soil respiration (soda lime, IRGA and solid-state open path sensors) and methods to partition flux in its main biological compartments. Besides the observed high functional redundancy and resilience of soil microbial communities, our results points to mechanisms of plant-soil interactions as main controllers of soil C dynamics.
