El desarrollo de edificios tobáceos origen fluvial se asocia a menudo con fases cálidas y húmedas cuaternarias son comúnmente empleados como indicadores climáticos. En el presente trabajo estudia depósito tobáceo Holoceno del Nogal Batán, situado en valle río Las Parras (Cordillera Ibérica, NE España), bajo una perspectiva cronológica, estratigráfica palinológica. La acumulación tobácea 8,2 m e...

Freshwater ecosystems are positioned at low levels in the landscape and receive large inputs of diverse plant-based detritus, a major source of energy for consumers in aquatic ecosystems. We conducted field experiments in Urbana, IL to determine the independent and combined effects of leaves of common tree species including the northern red oak (Quercus rubra L.), sugar maple (Acer saccharum M...

This study was conducted to investigate the effects of increasing levels of extracts of Byrsonima crassifolia, Celtis pallida, Enterolobium cyclocarpum, Fraxinus excelsior, Ficus trigonata, Phoradendrom brevifolium and Prunus domestica on in vitro gas production (GP) and ruminal fermentation of a high concentrate diet. Plant extracts were prepared at 1 g dry matter (DM)/8 mL of solvent mixture ...

Although noncrop woody plants in crop field landscapes serve multiple functions, the modernization of agriculture has threatened their preservation. In this study, isolated woody plants used as farmland boundary markers were investigated in Ibaraki Prefecture in the eastern Kanto region. A total of 2001 individuals of 50 species were found around 177 equidistantly spaced points. The most freque...

Celtis sinensis is an introduced plant species to the southeastern region of Queensland that has had a destructive affect on indigenous plant communities and its pollen has been identified as an allergen source. Pollen belonging to C. sinensis was sampled during a 5-year (June 1994-May 1999) atmospheric pollen-monitoring programme in Brisbane, Australia, using a Burkard 7-day spore trap. The se...

The Mediterranean basin has been a refugium for relict plant taxa and native laurophyllic forests. Latium coasts and, especially, the Antica Lavinium site, host forest communities, whose natural importance is enriched by their cultural value. Here, we aim at investigating ecological framework, historical values, management over time, of communities that have Laurus nobilis Celtis australis as p...
