International study on Artemia : 15. Effect of light intensity on hatching rate of Artemia cysts from different geographical origin [PDF]

open access: yes, 1981
Artemia cysts from 4 geographical strains were incubated under standard hatching rates increased with increasing light intensities. The light-intensity threshold at which the maximal hatching rate was attained, varied from strain to strain.

Geographical Variation in Responses to Photoperiod and Temperature by \u3ci\u3eLeptinotarsa decemlineata\u3c/i\u3e (Coleoptera: Chrysomelidae) During and After Dormancy [PDF]

open access: yes, 1988
The intensity of diapause has a distinct seasonal pattern in the Colorado potato beetle, Leptinotarsa decemlineata (Say). During August, temperature and photoperiod only slightly affected the very intense diapause in field populations. By summer\u27s end,

Movement analyses of wood cricket ( Nemobius sylvestris) (Orthoptera: Gryllidae) [PDF]

open access: yes, 2010
Information on the dispersal ability of invertebrate species associated with woodland habitats is severely lacking. Therefore, a study was conducted examining the movement patterns of wood cricket (Nemobius sylvestris) (Orthoptera: Gryllidae) on the Isle

Seasonal and altitudinal regulation of embryonic and nymphal development in Allonemobius fasciatus (Orthoptera:Gryllidae) [PDF]

open access: yes
The physiological adaptations involved in the seasonal and altitudinal regulation of the life cycle in Allonemobius fasciatus were studied. This species maintains a univoltine life cycle with an embryonic diapause over an altitudinal gradient of as large
