The ecology and significance of below-ground bud banks in plants

Publications Posted on: July 10, 2019
Background: Below-ground bud banks have experienced much recent interest due to discoveries that they (1) account for the majority of seasonal population renewal in many communities, (2) are crucial to regeneration following disturbance, and (3) have important consequences for plant population dynamics and plant and ecosystem function across a number of habitats.

Examining the patterns and processes of grassland resiliency to drought

Projects Posted on: November 02, 2018
With increasing temperatures due to climate change and the inherent interannual variability in precipitation of most grasslands, droughts will likely increase in frequency and intensity across the Great Plains. Precipitation legacies from previous years can impact current year productivity in arid grasslands by shifting tiller and bud bank densities of the dominant grasses. Belowground bud survival during drought and the ability of buds to break dormancy following drought are key to maintaining a resilient grassland in both arid and mesic grasslands.

Greater bud outgrowth of Bromus inermis than Pascopyrum smithii under multiple environmental conditions

Publications Posted on: August 17, 2016
Tiller recruitment of perennial grasses in mixed-grass prairie primarily occurs from belowground buds. Environmental conditions, such as temperature, soil moisture and grazing can affect bud outgrowth of both invasive and native perennial grasses. Differential bud outgrowth responses of native and invasive species to climate change and grazing could alter competitive interactions that have implications for future land management.

Bud-bank and tiller dynamics of co-occurring C3 caespitose grasses in mixed grass prairie

Publications Posted on: March 23, 2016
Tiller recruitment from the belowground bud bank of caespitose grasses influences their ability to monopolize local resources and, hence, their genet fitness. Differences in bud production and outgrowth among tiller types within a genet and among species may explain co-occurrence of caespitose grasses.

Evaluating the potential role of belowground bud banks in providing resistance and resilience to climate change in grassland ecosystems

Projects Posted on: April 22, 2015
Stem initiation of key mixed-grass prairie species will be examined under a range of temperature, clipping, and moisture treatments in a series of growth chamber and greenhouse experiments.
