20.500.12556/DKUM-67168 Cold tolerance in terrestrial invertebrates inhabiting subterranean habitats Most organisms are able to survive shorter or longer exposure to sub-zero temperatures. Hypothetically, trogloxenes characterized as not adapted, and troglophiles as not completely adapted to thermally stable subterranean environment, have retained or partially retained their ability to withstand freezing, while most troglobionts have not. We tested this hypothesis experimentally on 37 species inhabiting caves in Slovenia, analyzing their lower lethal temperatures in summer and winter, or for one season, if the species was not present in caves during both seasons. Specimens were exposed for 12 hrs to 1°C-stepwise descending temperatures with 48 hr breaks. In general, the resistance to freezing was in agreement with the hypothesis, decreasing from trogloxenes over troglophiles to troglobionts. However, weak resistance was preserved in nearly all troglobionts, which responded in two ways. One group, withstanding freezing to a limited degree, and increasing freezing tolerance in winter, belong to the troglobionts inhabiting the superficial subterranean habitats. The other group, which equally withstand freezing in summer and winter, inhabit deep subterranean or other thermally buffered subterranean habitats. Data on cold resistance can thus serve as an efficient additional measure of adaptation to particular hypogean environments. endemites superficial subterranean habitats trogloxenes troglophiles troglobionts endemiti podzemni habitati troglokseni troglofili troglobionti true true true University of South Florida Libraries Angleški jezik Slovenski jezik Znanstveno delo 2017-08-04 11:21:34 2017-08-04 11:23:11 2026-09-03 11:57:28 2019-07-11 16:11:16 2014 0 0 str. 265-272 št. 3 Letn. 43 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2013-10-24 2014-03-26 2014-04-07 0392-6672 591.9:551.44 858900 20595208 10.5038/1827-806X.43.3.3 0392-6672 URN:SI:UM:DK:FOOP7CFS International_Journal_of_Speleology_2014_Novak_et_al._Cold_tolerance_in_terrestrial_invertebrates_inhabiting_subterranean_habitats.pdf International_Journal_of_Speleology_2014_Novak_et_al._Cold_tolerance_in_terrestrial_invertebrates_inhabiting_subterranean_habitats.pdf 1 701ED0982B8BA3A79372D5558DEAAAA2 5354206cf7894ae9210f1f955b35b5302fe5a1b098ae5867728afb7a86b1a083 7b20a61f-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/f653a59e-73f7-4fdd-bc57-3100078f16f5 https://dk.um.si/Dokument.php?lang=slv&id=114865 http://scholarcommons.usf.edu/ijs/vol43/iss3/3/ 1 https://dk.um.si/Dokument.php?lang=slv&id=114864 Fakulteta za naravoslovje in matematiko 0 0 0
