35 p, 111.3 KB Climate and taxonomy underlie different elemental concentrations and stoichiometries of forest species: the optimum “biogeochemical niche” / Sardans i Galobart, Jordi (Centre de Recerca Ecològica i Aplicacions Forestals) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia)
We previously hypothesised the existence of a “biogeochemical niche” occupied by each plant species. Different species should have a specific elemental composition, stoichiometry and allocation as a consequence of their particular metabolism, physiology and structure (morphology) linked to their optimal functioning under the environmental (abiotic and biotic) conditions where they have evolved.

Plant-invasive success is one of the most important current global changes in the biosphere. To understand which factors explain such success, we compared the foliar traits of 41 native and 47 alien-invasive plant species in Oahu Island (Hawaii), a location with a highly endemic flora that has evolved in isolation and is currently vulnerable to invasions by exotic plant species.

56 p, 1.4 MB Variation in roots and mycorrhizae in tropical rainforests in relation with fertility / Meus, Kris ; Verbruggen, Erik ; Jennifer ; Universiteit Antwerpen
The nutrient balances of nitrogen (N), carbon (C) and phosphorous (P) in ecosystems are changing while its effects on the Earth’s system are still a research enigma. Roots and mycorrhizae in the tropics are important in global C storage and nutrient cycling, which makes it necessary to understand how these belowground structures react to different nutrient levels.

80% of Volatile Organic Compounds (VOCs) that are emitted every year to the atmosphere come from biogenic sources (BVOCs), where many different families are included, such as isoprenoids. The production and emission of those compounds is influenced by environmental variables such as light and temperature. [...]
