The Evolution Of The Eastern North American Isopods Of The Genus Asellus (Crustacea: Asellidae) Part Ii, Laurence E. Fleming
The Evolution Of The Eastern North American Isopods Of The Genus Asellus (Crustacea: Asellidae) Part Ii, Laurence E. Fleming
International Journal of Speleology
This paper is the second in the three part series dealing with the evolution of the North American isopods of the genus Asellus. The generic status of Asellus is discussed with emphasis placed on the newly proposed genera of Henry and Magniez (1968). Use is made of comparative anatomical and where feasible statistical methods during this investigation. The first, shorter portion of the study deals with the presentation of evidence supporting the viewpoint that if "Pseudobaicalasellus” is to be considered a valid genus then it must include the members of the Cannulus Group of Steeves (1965). The …

Breeding And Fecundity In A Subterranean Mysid, Lepidomysis Longipes (Pillai And Mariamma), C. N. Nath
International Journal of Speleology
The hypogean mysid, Lepidomysis longipes has a breeding period extending from December to April with the peak period in March. A secondary breeding period appears in August and September. The females have low fecundity and carry a maximum of nine eggs. Development is delayed due to lack of nourishment in the environment. The mysids breed only once a year.

International Journal of Speleology
Differences between tropical and temperate cave communities are an important topic in the actual biospeleological thinking. Among the most striking differences is the paucity of terrestrial troglobites in tropical caves. This fact may depend on the higher energy input into tropical caves which lessens the selection pressures for energy-economizing troglobite adaptations. Consequently evolutionary rates would be slowed in tropical caves and, in a date group, troglobites would appear later in such caves than in temperate ones with lower energy input. In order to investigate this point the authors studied the degree of adaptation to the cave environment in two species …
