Living unicellular eukaryote Tetrahymena pyriformis as a model for study [PDF]

open access: yes, 2011
Some animals are able to survive for a long time under conditions of drastically reduced oxidative metabolism, called metabolic depression. The most investigated type of metabolic depression is hibernation.

Precise Measures of Orbital Period, Before and After Nova Eruption for QZ Aurigae [PDF]

open access: yes, 2019
For the ordinary classical nova QZ Aurigae (which erupted in 1964), we report 1317 magnitudes from 1912--2016, including four eclipses detected on archival photographic plates from long before the eruption.

Physiochemical and histological study on the effect of the hibernation on the liver of Uromastyx acanthinura (Bell, 1825).

open access: yesمجلة المختار للعلوم, 2013
This study described the changes in the liver of Uromastyx acanthinura (Bell, 1825) males and females during hibernation and activity seasons. The results revealed that, hibernation causes increase fatty liver and pigment cells with abundant damage ...

Hibernation Revived by Weak Magnetic Braking [PDF]

open access: yes, 2006
Cataclysmic variables undergo periodic nova explosions during which a finite mass of material is expelled on a short timescale. The system widens and, as a result, the mass-transfer rate drops.

Hibernation Period in Some Land Snail Species (Gastropoda: Helicidae): Epiphragmal Structure and Hypometabolic Behaviors

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2021
In this study, the hypometabolism behavior, epiphragm formation process, and the mineral composition of the epiphragmal structure of the Helix pomacella, Eobania vermiculata, Helix melanostoma, and Helix asemnis land snails were investigated during the ...

Over-Winter Survival and Nest Site Selection of the West-European Hedgehog (Erinaceus europaeus) in Arable Dominated Landscapes

open access: yesAnimals, 2020
The West-European hedgehog (Erinaceus europaeus) has declined markedly in the UK. The winter hibernation period may make hedgehogs vulnerable to anthropogenic habitat and climate changes.

Geographic body size variation in ectotherms: effects of seasonality on an anuran from the southern temperate forest [PDF]

open access: yes, 2015
Indexación: Web of Science; Scopus.Background: Body size variation has played a central role in biogeographical research, however, most studies have aimed to describe trends rather than search for underlying mechanisms.

Single-Cell Atlas Reveals the Hemocyte Subpopulations and Stress Responses in Asian Giant Softshell Turtle during Hibernation

open access: yesBiology, 2023
Hibernation in turtle species is an adaptive survival strategy to colder winter conditions or food restrictions. However, the mechanisms underlying seasonal adaptions remain unclear.

Nova Aquilae 1918 (V603 Aql) Faded by 0.44 mag/century from 1938-2013 [PDF]

open access: yes, 2013
We present the light curve of the old nova V603 Aql (Nova Aql 1918) from 1898-1918 and 1934-2013 using 22,721 archival magnitudes. All of our magnitudes are either in, or accurately transformed into, the Johnson $B$ and $V$ magnitude systems.
