Seed dispersal by neotropical seed predators

American Journal of Primatology, 1998
From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms.

Seeds of Dementia

Scientific American, 2013
The article discusses how a chain reaction of toxic proteins may help explain neurodegenerative disorders such as Alzheimer's, Parksinson's, and amyotrophic lateral sclerosis (ALS). Topics include an overview of proteinaceous infectious particle (PrP), called prions, research in the 1980s by Stanley B.

Pollination, Seed Predation, and Seed Dispersal

2006
Insects are the major agents of pollination, seed predation, or seed dispersal in many ecosystems. Animal pollinators are critical to pollination and survival of many plant species that typically occur as widely scattered individuals, especially in deserts and tropical forests. Seed predators often consume the entire reproductive effort of host plants.

Effect of Seeding Date, Seeding Rate, and Seed Treatments on Saltgrass Seed Germination and Establishment

Crop Science, 2008
Inland saltgrass [Distichlis spicata var. stricta (L.) Greene], native to the western United States, has potential for use as a turfgrass and a revegetation species on saline sites. This study was conducted (i) to evaluate the effect of seeding date, seeding rate, and seed treatments on saltgrass establishment; and (ii) to determine the required ...

SEED TECHNOLOGY AND SEED ENHANCEMENT

Acta Horticulturae, 2008
This paper reviews the uses, properties and manufacture of the main array of ‘seed enhancement technologies’ that are implemented in current commercial practice, with a particular emphasis on cultivated horticultural and ornamental species. Recent developments, as well as some of the newer technical approaches that are still in the research or at ...
