Historic range of longleaf pine savannas

Problem

  • Historic range: nearly 100 million acres

  • Present day: less than 5 million acres

  • Long legacy of fire suppression

Consequences of “woody encroachment”?

Causes of “woody encroachment”?

Current focus:

  • Interactions between plants and microbes in the soil
  • Fire suppression

Approach

  • Field studies

  • e.g. “How does variation in fire severity affect plants and soil microbes?”

LSU AgCenter’s Lee Memorial Forest, FranklintonLA

Low fuel

Mean fuel

High fuel

Approach

  • Field studies

  • e.g. “How does variation in fire severity affect plants and soil microbes?”

But, there are limitations to what we can do in the field!

  • Lots of species in the system! How to generalize?

  • Fires happen every 2–3 years – how to make long-term predictions?

How to tackle this challenge?

Empty patches

\[\frac{dP_{00}}{dt} = \overbrace{\mu_g P_{g0} +\mu_s P_{s0}}^{\substack{\text{ plant mortality}}\\{\text{in unconditioned soil}}} + \overbrace{d_g P_{0g} + d_s P_{0s}}^{\substack{\text{microbial decay} \\ \text{in empty patches} }} - \\ \overbrace{r_gP_{00}(P_{{g0}+}P_{gg}+P_{gs})}^{\text{grass establishment}} - \\ \overbrace{r_sP_{00}(P_{{s0}+}P_{ss}+P_{sg})}^{\text{shrub establishment}} \]

Patches with plant present but soil not yet conditioned

\[\frac{dP_{g0}}{dt} = \overbrace{r_gP_{00}(P_{g0} + P_{gg} + P_{gs})}^{\substack{\text{grass establishment in} \\ \text{unconditioned soil}}} - \overbrace{c_g P_{g0}}^{\substack{\text{soil conditioning}\\\text{by grass}}} - \overbrace{\mu_g P_{g0}}^{\text{grass mortality}}\]

\[\frac{dP_{s0}}{dt} = \overbrace{r_sP_{00}(P_{s0} + P_{ss} + P_{sg})}^{\substack{\text{shrub establishment in } \\ \text{empty patch}}} - \overbrace{c_sP_{s0}}^{\substack{\text{soil conditioning}\\\text{by shrub}}} - \overbrace{\mu_sP_{s0}}^{\text{shrub mortality}}\]
Patches with plants and corresponding soil conditioning effects

\(\frac{dP_{gg}}{dt} = c_g (P_{g0} + P_{gs}) + r_g m_{gg} P_{0g}(P_{g0} + P_{gg} + P_{gs}) - \mu_g P_{gg}\)

\(\frac{dP_{ss}}{dt} = c_s (P_{s0} + P_{sg}) + r_s m_{ss} P_{0S}(P_{s0} + P_{ss} + P_{sg}) - \mu_s P_{ss}\)
Patches with no plant present but conditioned soil persists

\(\frac{dP_{0g}}{dt} = \mu_g P_{gg} + \mu_s P_{sg} - r_g m_{gg} P_{0g}(P_{g0}+P_{gg}+P_{gs}) - r_s m_{sg} P_{0g}(P_{s0}+P_{ss}+P_{sg})\)

\(\frac{dP_{0s}}{dt} = \mu_s P_{ss} + \mu_g P_{gs} - r_s m_{ss} P_{0s}(P_{s0}+P_{ss}+P_{sg}) - r_g m_{gs} P_{0s}(P_{s0}+P_{ss}+P_{sg})\)

Patches with plants growing in the other plant’s conditioned soil

\(\frac{dP_{sg}}{dt} = r_s m_{sg} P_{0g} (P_{s0} + P_{ss} + P_{sg})\)

\(\frac{dP_{gs}}{dt} = r_g m_{gs} P_{0s} (P_{g0} + P_{gg} + P_{gs})\)

Increasing emphasis in using math and computers for biological problems

Biology education is evolving to keep up…

… but we need your help!

  • We want to know:
    • What is your experience with math and computers?
    • What is your enthusiasm for math and computers?
    • How can quantitative/computational biology help you?

Help us by completing a short survey!

Benefits:

  • Help design future of biology education at LSU and beyond

  • Chance to win $25 giftcard

  • Responses will be used for research articles - participation is completely anonymous and voluntary

Interested in learning about fieldwork, mathematics, and computers in ecology?
We’re always open to undergraduate researchers!
