Are they two seeds in a pod? Comparing seed rain recovery in grasslands using artificial grass carpets versus sticky traps

Applications in Plant Sciences
Premise Seed dispersal is a critical process for plant community assembly; however, natural rates of seed arrival are rarely quantified compared with other assembly mechanisms, especially in herbaceous communities.

Impact of grazing and desertification in the Chihuahuan desert: plant communities, granivores and granivory

, 2000
Over the past 150 years, Chihuahuan Desert grasslands have been degraded into less productive shrublands (desertification). This vegetation change is believed to be related to overgrazing by domestic livestock.

Cafeteria-style experiments for granivory and its methodological issues

, 2014
La oferta de semillas ha sido el método más usado en los estudios experimentales de granivoría. Estos experimentos presuponen que las semillas faltantes en cada tratamiento han sido consumidas por los granívoros, y que el consumo experimental es similar ...

Seed Packaging and Seed Characteristics in a Raphanus Hybrid-Derived Lineage [PDF]

, 2012
Hybridization is accountable for a considerable number of plant species of which some are remarkably good invaders. Interspecific hybridization can promote plant invasiveness by leading to (1) higher reproductive output, (2) higher genetic diversity, and

Efectos de la producción de semillas y la heterogeneidad vegetal sobre la supervivencia de semillas y el patrón espacio-temporal de establecimiento de plántulas en Araucaria araucana Araucaria araucana temporal and spatial seedling establishment patterns: masting, seed predation and understory vegetation effects

Revista Chilena de Historia Natural, 2009
El establecimiento de plántulas puede estar limitado por la producción de semillas y asociada a la producción intermitente y sincronizada de semillas (masting) y/o por granivoría, o por falta de micrositios aptos para la germinación y crecimiento de las ...
