(1) The cold hardiness of four species was studied in respect of supercooling ability, cryoprotective substances, chill-coma temperatures and survival under anaerobiosis. The effects of low temperature acclimation and starvation […]
1. Mean supercooling points of eleven species of arthropods (three Collembola, seven Acari and one Diptera) ranged from ‐6.2 to ‐9.4°C (high group), and from ‐17.7 to ‐31.0°C (low group). […]
1. 1. A selective review is made of the information on cold hardiness in the following taxonomic groups: Protozoa, Platyhelminthes, Rhynchocoela, Rotifera, Nematoda, Mollusca, Annelida, Tardigrada, micro-Arthropoda (Collembola & Acari) […]
Two calc-alkaline plutonic complexes. Bazman and Natanz, intruded through the south-eastern active and south-western ancient continental margins of Central Iran, Have been dated by the Rb-Sr whole-rock isochron method at […]
The 4C DNA amounts of 23 native or alien angiosperms from South Georgia, or the maritime Antarctic, ranged from 1.4 to 80.5 pg (in 14 monocots) and from 1.3 to […]
Recent research strongly suggests that harmonic radiation from electrical power distribution networks in industrialized regions (PHLR) has a significant effect on the occurrence of VLF waves and the energetic electron […]
The distribution of Chromobacterium on islands of the Scotia Ridge and Antarctic Peninsula was monitored during 1975–81. Three groups of strains were recognized: (1) an acid-tolerant group at South Georgia […]
