Ice Accretion Under Natural and Laboratory Conditions

Radiotelemetric study of hibernation under natural and laboratory conditions.

WANG, LAWRENCE C. H. Radiotelemetric study of hibernation under natural and laboratory conditions. Am. J. Physiol. 224(3): 673-677. 1973.-The body temperature of hibernating Richardson’s ground squirrel (Spermophilus richardsom) was measured by radiotelemetry both in its natural habitat and in the laboratory. Under natural conditions, hibernation extended from mid-September to early March. The ...

Growth of Heterostegina depressa under natural and laboratory conditions

The use of micro-computed tomography (μCT) provides a unique opportunity to look inside the shells of larger benthic foraminifera to investigate their structure by measuring linear and volumetric parameters. For this study, gamonts/schizonts and agamonts of the species Heterostegina depressa d'Orbigny were examined by μCT; each single chamber's volume was digitally measured. This approach enabl...

OBSCURA AND DROSOPHILA PERSIMILIS UNDER NATURAL AND UNDER LABORATORY CONDITIONS By THEODOSIUS DOBZHANSKY

Cryopreservation of Smirnovia iranica (Sabeti) Seeds and Evaluation of Cryopreserved Seeds under Laboratory, Greenhouse and Natural Habitat Conditions

Smirnovia iranica (Sabeti) synonym: Smirnovia turkestana (Bunge) is a deciduous perennial bushy species of the Fabaceae (Papilionaceae) family. The species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. They have an important role in natural vegetation of desert and sand dune stabilization. Limited growing areas, grazing due to good pa...

Predation in two species of leech under laboratory conditions

Two 60 day experiments on predation behavior of leeches were conducted concurrently. In the first, medicinal leeches, Hirudo orientalis (Utevsky and Trontelj, 2005) were fed to satiation on bovine blood and subsequently transferred into two large opaque plastic containers of equal size but with differing temperatures, 6-7?C and 23-24?C, containing starved Erpobdella octoculata (L.). At the high...
