SPERMATOPHORES OF SOME NORTH AMERICAN SCORPION S (ARACHNIDA, SCORPIONES )
- O. Francke
- Biology

It is postulated that the Chaerilidae are more closely related to scorpions with lamellifor m sperMatophores than they are to buthids, and their spermatophores are probably of a lamellIfor m "type" .

The theoretical method uses a progression factor of 1.26 in linear dimensions at each molt to predict the number of molts required by young scorpions of known instar to reach adult size.
Are There Any Bothriurids (Arachnida, Scorpiones) in Southern Africa?
- O. Francke
- Biology
- 1982
As Gondwanaland fragmented due to plate tectonics, each of the southern continents carried with it a sample of the ancestral biota, and bothriurids would be predicted to occur in southern Africa as well.
Temperature Preferences of Four Species of Fire Ants (Hymenoptera: Formicidae: Solenopsis)
- J. Cokendolpher, O. Francke
- Environmental Science
- 1985
Temperature preferences are predicted to occur in insects due to homeostatic considerations. Enzymes should be adapted to function optimally within the narrow range of temperatures encountered by an…
