Viability and Vigor of Dura, Pisifera and Tenera Oil Palm (Elaeis Guineensis Jacq.) Pollen [PDF]
, 2010 Selecting pollen with high viability and vigor are important for ensuring the success of oil palm seed production through controlled pollination. Therefore, an estimation of pollen viability and vigor is essential for fruit and seed setting.

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]
, 2008 1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

American Journal of Botany, EarlyView.Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Applications in Plant Sciences, EarlyView.Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...
