L. Koch to alternate temperatures of 12[degree]C and 32[degree]C, structural anomalies were caused in all abdominal metameres of that spider. The changes in the shape of abdomen and the persistence of stump appendages in the prothelar and postthelar zone of the abdomen are considered atavistic characteristics related to the phylogenetic past of Arachnida.}, keywords = {Abiotic, adult, Development, effect on opisthsoma anomalies in adult]., Evolution, factors, General morphology, Life cycle and development, Opisthosoma anomalies, Parasites diseases and disorders, phylogenetic significance] [Embryo development / /, Physical factors, significance] [Diseases and disorders / Anomalies / ] [Temperature / /, Systematics, Tegenaria atrica (Araneae)., Tegenaria atrica [Opisthosoma / / effect of temperature during embryo, temperature during embryo development, Temperature effect on opisthosoma anomalies in adult] [Phylogeny / /}, isbn = {0867-1656}, url = {://ZOOREC:ZOOR13900033055}, author = {Jacunski, Lech} }
