Diverse plant functions (e. g. , growth, storage, defense and anti-stress mechanisms) use elements disproportionally. We hypothesized that plants growing under different abiotic and biotic conditions would shift their elemental compositions in response to a very severe drought. [...]

11 p, 578.9 KB Variations in chemistry of macerals as refl ected by micro-scale analysis of a Spanish coal / Mastalerz, M. (Indiana University. Indiana Geological Survey) ; Hower, J.C. (University of Kentucky. Center for Applied Energy Research) ; Taulbee, D.N. University of Kentucky. Center for Applied Energy Research
An Oligocene lignite (Ebro Basin, Spain) and its density fractions were analyzed petrographically and with microscale techniques (electron microprobe and micro-FTIR) to gain insight into differences between individual macerals of low rank high-sulfur coal. [...]

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.

14 p, 289.2 KB Elemental ratios in sediments as indicators of ecological processes in Spanish reservoirs / López Laseras, Pilar (Universitat de Barcelona. Departament d'Ecologia) ; Navarro, E.

Reservoir sediments are important archives of biogeochemical data, reflecting ecological processes that occur at the watershed system. In this paper, a preliminary study of the limnological significance of major element composition and element ratios in sediments of Spanish reservoirs is presented, by analysing two data-sets from different limnological regions. [...]
El sedimento de los embalses constituye un importante registro de datos biogeoquímicos, ya que refleja los procesos ecológicos que tienen lugar en el conjunto de la cuenca hidrográfica. A partir del análisis de dos conjuntos de datos obtenidos en distintas regiones limnológicas, se presenta una aproximación preliminar al significado limnológico de la composición química y los cocientes elementales en el sedimento de los embalses españoles. [...]
