Disturbance chapter



John,
I'm just getting this into the archives for completeness.  I'll put into
proper format later.

Bob:

Attached below is the current version of the Disturbance chapter outline.  I
have emailed it to the potential authors and asked that they return any
comments for revisions to me withn a week.  At that point, I will revise the
outline again if needed and email it to you.

As for the Succession outline, once I get the marsh material from Osgood and
Zieman, I will follow along with the revision for that chapter.  My hope is
to have that one nailed by early April

Thanks again for the productive meeting,

Don



Section II. Response of landscape to disturbance

II.2. Barrier Island (Young, Day, Kochel, Osgood, and Zieman)

A.  Introduction (relate to discussions in previous chapters (e.g. I.0.b and
I.2))
     1.  Landscape units are interrelated
     2.  Landscape units are dynamic
     3.  Disturbance accelerates/alters landscape dynamics
     4.  Disturbance and state change Hayden et al BioScience paper
     5.  Disturbance forms (if not in Intro to Section II)
          a.  Spring tides
          b.  Northeaster storms
               i.  flooding
               ii.  overwash
               iii.  wind damage
          c.  Hurricanes
          d.  North Inlet - Hugo results ?
          e.  Others (fire, large herbivore grazing, thunderstorms)
B.  Beaches
     1.  Profile vs storm response
          a.  form vs stability
          b.  location vs stability
     2.  Seasonality vs disturbance and response
     3.  Overwash
          a.  size and frequency
          b.  locations
          c.  response (landscape and vegetation)
          d.  Fahrig et al paper
C.  Upland
     1.  Introduction
          a.  importance of topographic position
               i.  swale vs dune
               ii.  distance from ocean beach
          b.  effect of vegetation type )grassland vs shrub thicket
     2.  Effects and responses (relate to disturbance forms (section A.5)
          a.  flooding patterns
          b.  changes in soil  and groundwater salinity
          c.  response of vegetation, especially to Oct '91 storm
          d.  revisit Fahrig et al. paper
          e.  thicket gaps (Young, Crawford and Day work)
               i.  small vs large gaps/disturbance
               ii.  plant response and the effects of thicket age
D.  Backbarrier marshes
     1.  Introduction
          a.  island dynamics dictate stage of marsh development (Hayden et
al., Dame et al, Childers)
          b.  position of present backbarrier marshes
               i.  w/r/t/ landscape
               ii.  w/r/t/ time
                    A)  short term - S. Parramore / Oct 91 sotrm
                    B)  long term - S. Hog chronosequence
     2.  Comparsion/contrast with other VCR marshes: role of island dynamics
(overwash)
          a.  structure
               i.  position w/r/t tidal range
               ii.  sediment characteristics (lots and lots of sand)
               iii.  flora and fauna distribution
          b.  processes
               i.  primary production
               ii.  hydrology
               iii.  nutrient cycling (also covered in separate chapter)
     3.  Comparison/contrast with other coastal marsh ecosystems
          a.  landscape dynamics
          b.  sediment characteristics
          c.  tidal range (compare to other coastal areas)
E.  Synthesis
     1.  Disturbances contribute to distinct vegetation patterns on barrier
islands
     2.  Predicted response to sea level rise
          a.  increased frequency of overwash
          b.  movement on landscape (relate to Brinson et al '95)
     3.  Relate to Disturbance theory (e.g. Connell 1978)
     4.  Summarize relative to Hayden et al BioScience
     5.  Emphasize that these disturbance responses/processes affect
successional dynamics (i.e. autogenic changed to allogenic, Chapter
III.4)
