Her research focuses primarily on aspects of wetland plant ecology, including invasive plant ecology and management, native wetland seeds and seedlings, and wetland restoration. [1] Kettenring worked in several labs and research stations across the United States before obtaining a faculty position at Utah State University as a professor of ...
Frugivores and seed dispersal: mechanisms and consequences for biodiversity of a key ecological interaction. Biology Letters 7: 321–323. This paper discusses the consequences of losing frugivores as seed dispersers due to extinction and anthropogenic factors. Jordano, P. 2010. Pollen, seeds, and genes: the movement ecology of plants.
A 1994 study by Burkey found that seed predation did not follow a pattern supporting that of the Janzen–Connell hypothesis along a meaningful scale. Seeds within 1 metre from the trunk were highly predated. However, seeds reached their peak density while still under the canopy of their parent. The authors concluded that seed predation did not ...
Seed dormancy is an evolutionary adaptation that prevents seeds from germinating during unsuitable ecological conditions that would typically lead to a low probability of seedling survival. [1] Dormant seeds do not germinate in a specified period of time under a combination of environmental factors that are normally conducive to the germination ...
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.
The seed bank is one of the key factors for the persistence and density fluctuations of plant populations, especially for annual plants. [4] Perennial plants have vegetative propagules to facilitate forming new plants, migration into new ground, or reestablishment after being top-killed, which are analogous to seed bank in their persistence ability under disturbance.
A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.

A strawberry aggregate accessory fruit damaged by a mouse eating the seeds ().. Seed predation, often referred to as granivory, is a type of plant-animal interaction in which granivores (seed predators) feed on the seeds of plants as a main or exclusive food source, [1] in many cases leaving the seeds damaged and not viable.
