17 p, 3.0 MB Changes in the natural dynamics of Nothofagus dombeyi forests : population modeling with increasing drought frequencies / Molowny-Horas, Roberto (Centre de Recerca Ecològica i Aplicacions Forestals) ; Suárez, Maria Laura (Argentina. Consejo Nacional de Investigaciones Científicas y Técnicas) ; Lloret Maya, Francisco (Centre de Recerca Ecològica i Aplicacions Forestals)
Drought-induced episodes of tree mortality can determine forest dynamics and structure, particularly in forests dominated by single species. Short- and mid-term climate projections indicate that strong changes in annual precipitation may strike more often in northern Patagonia. [...]

14 p, 3.0 MB Plant community composition affects the species biogeochemical niche / Urbina Barreto, Ifigenia (Centre de Recerca Ecològica i Aplicacions Forestals) ; Sardans i Galobart, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Grau Fernández, Oriol (Centre de Recerca Ecològica i Aplicacions Forestals) ; Beierkuhnlein, Carl (Universität Bayreuth.

Institut für Botanik und Landschaftsökologie) ; Peñuelas, Josep (Centre de Recerca Ecològica i Aplicacions Forestals)
Nutrients are essential for plant development, and their availability and stoichiometric ratios can influence the composition of plant communities. We investigated the possibility of the reverse influence: whether the conditions of contrasting species coexistence determine foliar element concentrations and plant stoichiometry, that is, species biogeochemical niche (BN).

Stress-induced emissions of biogenic volatile organic compounds (VOCs) from terrestrial eco- systems may be one of the dominant sources of VOC emissions worldwide. Understanding the ecosystem stress response could reveal how ecosystems will respond and adapt to climate change and, in turn, quan- tify changes in the atmospheric burden of VOC oxidants and secondary organic aerosols.

20 p, 2.2 MB Spatial patterns reveal strong abiotic and biotic drivers of zooplankton community composition in Lake My´vatn, Iceland / Bartrons Vilamala, Mireia (Centre de Recerca Ecològica i Aplicacions Forestals) ; Einarsson, Árni (University of Iceland) ; Nobre, Regina L G (Universidade Federal do Rio Grande do Norte) ; Herren, Cristina M. (University of Wisconsin-Madison) ; Webert, Kyle C. (University of Wisconsin-Madison) ; Brucet, Sandra (Aarhus Universitet) ; Ólafsdóttir, Sólveig R. (Hafrannsóknastofnun) ; Ives, Anthony R. (University of Wisconsin-Madison)
Spatial patterns in the abundance of species are determined by local abiotic and biotic conditions, and by the movement of individuals among localities. For species distributed among discrete habitat "islands", such as zooplankton distributed among lakes, local conditions within lakes often dominate low movement rates among lakes to determine the composition of communities.
