Application of herb chronology: Annual fertilization and climate reveal annual ring signatures within the roots of US tallgrass prairie plants

  title={Application of herb chronology: Annual fertilization and climate reveal annual ring signatures within the roots of US tallgrass prairie plants},
  author={Justin R Dee and Michael W. Palmer},
The relatively new field of herbaceous root chronology (“herb chronology”) uses the annual rings of secondary xylem in roots of perennial forbs to analyze belowground secondary growth as a function of annual growth environment. By using three tallgrass forb species from long-term experiments within Konza prairie of northeastern Kansas (USA), we aimed to find the effects of fertilization, growing season temperature, and precipitation on annual secondary growth. For two of the three species, we… Expand
These results are the first evidence of herbaceous annual ring sensitivity to sudden amelioration of resources as well as a significant loss of aboveground biomass. Expand
Belowground annual ring growth coordinates with aboveground phenology and timing of carbon storage in two tallgrass prairie forb species.
This study provides a new physiological link between how ring chronologies in herbs often accord with growing-season environment and further dissecting this phenomenon is vital in unlocking the potential of herb chronology. Expand
Annual rings of perennial forbs and mature oaks show similar effects of climate but inconsistent responses to fire in the North American prairie–forest ecotone
For the prairie–forest ecotone of central North America, research of the effects of climate and fire on the annual growth of nonwoody plant types is currently needed to compliment dendrochronologicalExpand
Herb-chronology as a tool for determining the age of perennial forbs in tropical climates
Investigation of the applicability of herb-chronology on the tropical plant Pentalinon andrieuxii (Mull.) B.F. Hansen & Wunderlin shows that herb- Chronology is a potentially useful tool in determining the age of plants growing in tropical climates. Expand
A new approach towards climate monitoring in Rocky Mountain alpine plant communities: A case study using herb-chronology and Penstemon whippleanus
ABSTRACT The alpine ecosystem of the Rocky Mountains is experiencing significant increases in growing season length, summer maximum temperatures, and shifting patterns in precipitation. Alpine herbsExpand
Alpine plant growth and reproduction dynamics in a warmer world.
The results suggest that warming-induced responses in alpine plants will not be one-sided shifts to higher growth and reproduction, but rather multidimensional and spatiotemporally variable. Expand
Growth ring analysis of multiple dicotyledonous herb species—A novel community-wide approach
Anatomical analysis of roots and rhizomes is a suitable tool to study the population age structure of a large spectrum of perennial dicotyledonous herbaceous species and therefore opens new perspectives for demographic studies at the community level. Expand
Long- and short-term responses of Asclepias species differ in respect to fire, grazing, and nutrient addition.
Results indicate that A. syriaca will do best in settings with high nutrient loads, low competition, and no grazers, which indicates that milkweed species will respond differently when exposed to agricultural settings, with some less able to cope with land conversion to pasture or row-crop agriculture.

Growth rings in roots of medicinal perennial dicotyledonous herbs from temperate and subtropical zones in China
Clear variations in growth rings of different genus or species were characterized in this study, and these findings proved the feasibility of applying herbaceous plant growth rings in age identification of traditional Chinese medicine. Expand
Environmentally-Related Cherry Root Cambial Plasticity
Genotypes with moderate vessel lumen area are presumed to be both size-controlling and stable upon the drought events, and further field trials will be focused on the SV2 European ground cherry genotype, and OV13, OV32, andOV34 Oblačinska sour cherry genotypes. Expand


Growth rings in the roots of temperate forbs are robust annual markers.
The results of this study demonstrate that the growth rings in the roots of northern temperate forbs represent robust annual growth increments and can reliably be used in herb-chronological studies of age- and growth-related questions in plant ecology. Expand
Effect of climate on the growth of annual rings in the main roots of perennial forbs in an Inner Mongolian semi-arid grassland, China
Question: Is there a pattern in growth of annual rings in roots of perennial forbs in relation to climate and climate extremes in grassland ecosystems? Location: Semi-arid grassland in Duolun (42127Expand
Growth response of the alpine shrub, Linanthus pungens, to snowpack and temperature at a rock glacier site in the eastern Sierra Nevada of California, USA
Annual ring chronologies in high-elevation and high latitude plants have numerous, but largely unexplored, climatic, ecological and geomorphologic applications. This paper presents the firstExpand
Under pressure: how a Mediterranean high‐mountain forb coordinates growth and hydraulic xylem anatomy in response to temperature and water constraints
This study reinforces the evidence that the response of high-mountain plants to climatic change under simultaneous temperature and drought stress is complex and that models that simply assume an increase in elevation as a response to higher temperatures may fail to predict future responses to climate change.

Annual rings in native and introduced forbs of lower Michigan, U.S.A.
This study sampled established individuals of dicotyledonous perennial herbs in different habitats in lower Michigan and analyzed the main roots for the presence of growth rings in the secondary xylem, finding clearly demarcated growth rings among introduced species and in disturbed habitats.

Root Biomass Dynamics Under Experimental Warming and Doubled Precipitation in a Tallgrass Prairie
Human-induced climate change is expected to increase both the frequency and severity of extreme climate events, but their ecological impacts on root dynamics are poorly understood. We conducted aExpand
Interannual variability in primary production in tallgrass prairie: climate, soil moisture, topographic position, and fire as determinants of aboveground biomass
The lack of significant correlation between soil moisture with NPP on unburned sites suggests that factors other than water availability limit production in these sites, which is consistent with the concept that patterns of NPP in tallgrass prairie are a product of spatial and temporal variability in light, water, and nutrients.

Responses of a C4 Grass and Three C3 Forbs to Variation in Nitrogen and Light in Tallgrass Prairie
Estimates of potential whole-plant carbon uptake, based on leaf area distribution relative to available light and A as a function of light availability, agreed well with patterns of forb abundance and production. Expand
Evidence for life history changes in high-altitude populations of three perennial forbs.
Data for three ecologically distinct forb species provide evidence of a consistent shift toward more conservative and strongly constrained life histories at higher altitudes and indicate the possible importance of changes in selection pressures across strong environmental gradients on life history strategies within a single species.
