TLDR
The vegetative reproduction and dynamics of Andropogon gerardii, a dominant C4 perennial grass of the Great Plains of North America, were compared between tallgrass and northern mixedgrass prairie habitats and similar population growth rates occurred in both habitats.Abstract:
Plant species with wide distributions may differ in their population dynamics across their range, especially in contrasting habitats. Most tiller recruitment of perennial grasses occurs vegetatively from the belowground bud bank rather than from seed. Seed reproduction often occurs under a narrower range of environmental conditions than vegetative reproduction. As a result flowering and seedling recruitment patterns of a species often differ between contrasting habitats and across its range. How vegetative reproduction and bud bank dynamics of a species vary between contrasting habitats has not been well studied and could explain the differences in its persistence and productivity between habitats. Therefore, the vegetative reproduction and dynamics of Andropogon gerardii, a dominant C4 perennial grass of the Great Plains of North America, were compared between tallgrass and northern mixedgrass prairie habitats. Bud production and tiller recruitment in 10 populations were examined throughout an a...read more

The ecology and significance of below-ground bud banks in plants.
TL;DR: This review presents an overview of the role of bud banks in plant population renewal, examines bud bank life history, summarizes bud bank traits and their potential ecological implications, synthesizes the response of bud Banks to disturbance, and highlights gaps to guide future research.

Differences in below-ground bud bank density and composition along a climatic gradient in the temperate steppe of northern China

TL;DR: Belowground bud bank density decreases towards the dry, hot end of the climatic gradient, and bulb buds and tiller buds of tussock grasses seem to be more resistant to environmental stress than rhizome buds.

The disturbance and disturbance intensity of small and semi-fossorial herbivores alter the belowground bud density of graminoids in alpine meadows
TL;DR: It is suggested that disturbance by the plateau pika has different effects on belowground bud densities of graminoids versus forbs, and disturbance up to the optimal intensity may improve grazing quality of alpine meadow in the long term through increasing graminoid bud density.

The Compensatory Tillering in the Forage Grass Hordeum brevisubulatum After Simulated Grazing of Different Severity
TL;DR: The results indicated that different grazing severities in the jointing stage could promote the output of tillers with matter production capacity from vegetative reproduction modules, as well as improve the capability of compensatory growth.

TL;DR: This special issue on clonal plant ecology focuses on a set of pressing questions to highlight both the obstacles and opportunities to more explicitly incorporate clonal growth in research on plant ecology and evolution.

On the Relationship between Abundance and Distribution of Species
TL;DR: The general relationships between abundance and distribution developed here eventually should contribute to the understanding of the biogeography, population genetics, and evolution of species as well as the ecological attributes of populations and communities.

Risks of Population Extinction from Demographic and Environmental Stochasticity and Random Catastrophes.
TL;DR: The relative risks of extinction from environmental stochasticity and random catastrophes depend on the mean and environmental variance of population growth rate, and the magnitude and frequency of catastropheses.
