Some statements.

• Spatial ecology is the study of the
  interrelationship between organisms and their
  environment, with particular emphasis on the
  spatial nature of these interactions.
• Spatial analysis commonly requires the use of
  large, complex databases using software that is
  not specifically designed for ecological
  applications.
• The purpose of this talk is to help bridge the
  gap between people, software, data and the
  spatial analyses that are needed in modern
  ecological research.

• What is our aim of bringing GIS in our
  department?
• Explaining GIS with some examples out of our
• own database!
• Where are we standing at this moment?
• Discussion
• What is the future of GIS in our department?

Spatial ecology, what is our aim?

• The importance of space in explaining adaptation
  of organisms
• Species can adapt to local conditions via
  evolutionary changes but this adaptation can be
  hampered by gene-flow from other parts of the
  environment where different genotypes are
  favored.
• Spatial characteristics of the environment in
  which the focal population is located are
  therefore of crucial importance for our
  understanding of local adaptation. See the Animal
  population biology department and

From features to raster.

• Line data
• Point data
• Polygon data

Latitude

• Raster point features
• Raster Point features
• Raster polygon features

Longitude

• When data are in a raster (grid) layer there are
  several analyzing methods possible.
• Grid Query
• Grid Overlay
• Grid filtering
• Interpolatie. - Raster Combinations
• - Conversion
• - Reclassify
• - Zonal Statistics.
• - Kriging.

There are different interpolation techniques.
(Spatial analyst)

• Interpolation techniques.
• IDW (Inverse Distance Weighted)
• every point influence the other neighbor
  point , distance is of great influence ,useful
  by gradual differences
• The values are averaged.
• Spline Is used for making a smooth curve
  relation between the distance of the pionts.
• Kriging. With this technique you get the most
  reliable grid results.
• This is done in two steps before doing this
  interpolation technique
• 1. what is the relation between the points.
• 2. what is the max. distance from the weighing
  point.

Where are we standing at this moment?Projects
and pilot studies.

• What is the relationship between first egg-date
  and the vegetation composition on the Hoge
  Veluwe.
• Marcel Visser and Leonard Holleman
• The Pied Flycatcher.
• What is the relationship between arrival date
  and the vegetation composition of choice of
  breeding place on the Hoge Veluwe.
• Students project. (Maartje Oonk)
• Dispersion.
• What is the distribution of great tits, with
  different coping strategies, in different
  habitats (vegetation composition) as consequence
  of dispersal during settlement.
• Kees van Oers en Piet Drent.
• Territory occupation

  territories in relation to habitat and density
  and the composition of the tit population on the
  Westerheide.

56
What to do in the near future ?

• Collecting updates of vegetation-maps of our
  studie-areas.
• Hoge Veluwe, Oosterhout and Deelerwoud in
  progress
• Is the environment changing?
• Measuring possitions of nestboxes.
• Georefering.
• What will be the consequences of the database
  structures?
• Working in an online environment.
• GIS-format by data-input.
• Remote desktop.

57
What is the future of GIS in the our department
(CTE)?

• Can we do research on adaptation-strategies
  under a changing environment,
• whiteout monitoring (analyzing) the
  environment?
• Ask yourself!
• Will GIS be of any help to you, now or in the
  near future?
• Orther applications.
