Welcome to the Grasshopper Database
Information about grasshoppers has been collected at Konza Prairie Biological Station for more than 20 years. We have made available here eight years of data from 1983 to 1990. You can ask questions (queries) of the database. For example, if you want to know how many grasshoppers of each category ( like "Spur-throated" or "Slant-faced") were found in the unburned watersheds in 1983, go to Query 1 below and select the year "1983" and the "0" for unburned treatment. The database will make a table to give you the answer. Try asking the database different questions within the parameters it sets. Ask about different combinations of years, categories or fire treatments. Each Table gives you the numbers you asked for, but does not tell you what the numbers mean. You must learn how to interpret the numbers for yourself, as every researcher must do.
You can also use the database to find the relationship of grasshoppers to the weather data. If you leave the weather data window open or minimize it so you can call it back at any time, it might help you to interpret some of the data.
There are three tables in the grasshopper database. Table One has general information in nine fields: data code, date, watershed, soil type, replications, time, wind speed (mph), temperature (°C) and cloud cover (%). Table Two has the grasshopper information in six fields: code, watershed, soil type, replication, species code, species name and quantity. This table has more than 1000 records. Table Three has the names of the grasshoppers including the common name, species name, and category. If you want to see the details of those tables, just click on the table and it will appear.
The following queries look for relationships between the number of grasshoppers and environmental conditions. For example, if you are interested in finding the relationship between numbers of grasshoppers collected and temperature, select the year and the temperature range. The database will provide a table with your answer.
There are two soil series in the three watersheds. One is the Florence series (Fl) which consists of moderately deep, sloping, or moderately steep soils on upland. The surface layer of this series is very dark cherty silt loam or cherty silty clay loam. The other is a Tully series (Tu) which is located on a plane or slightly concave base of a hill. It consists of deep, gently sloping or sloping soils with a surface layer of silty clay loam.
