1. EXTERNAL SITES
- Metric tape measures
One meter (or lower increment) sticks, ropes, PVC pipes
(A good size indicator for photographs is a stick of any designated length, painted white, with black electrical tape wound at measured stated intervals e.g. every 10 or 50 cm.)
- Metric quadrats: full, 1/2, 1/4, 1/10 m
It is imperative that whatever measuring device is used that it be clearly visible in all images that are presented of the site. Fractional intervals along the transect markers must also be visible
2. LABORATORY BASED SITES
Metric rulers
Stage and ocular micrometers
Linear and quadrat inscribed dishes and plates
3. HORIZONTAL AND VERTICAL TRANSECTS
Although most biological systems are perhaps best studied by the establishment of horizontal transects, there are some sites that can only be investigated by vertical transects into the system. These latter transects are best seen in mud and sand flat habitats where the inflora and infauna may only be investigated by taking vertical cores and dividing along a vertical transect, or on a cliff face or through a forest canopy. Vertical sites may also be established into and through systems such as plants and animals, or parts of organisms.
4. CONTRIBUTING YOUR TRANSECTS TO THIS SITE:
In order to collaborate with us in building this resource for transect investigations, you may do the following: If you are able to put your transect images on your own web site, just send us the URL and file location and we will designate a number reference and hyperlink it from our index of transects at this location. Or send your transect photo strips along with any additional information you can provide on physical factors or organism identification by e-mail to the following address:
Send comments to: Garry Fletcher
Be sure to include as much information as possible about the site. For example,
Temperature variations along the transect
Elevations
Measurements of sunlight intensity
Any other measurements that may help to relate abiotic effects to occurrence of organisms.
Information about the species that are visible in the transect. ( Identification, known associations, etc.). Photos, drawings or maps should be sent as picture files (.jpg or .jpg extensions), you may also send them as zipped files ( using pkzip) . Text materials can be sent as ordinary e-mail text files. (If it is possible to send text information already done in hypertext as a .htm file, that would be preferred.)
