Given the critical role of metabolism in the life history of all organisms, there is particular interest in understanding the relationship between individual metabolic phenotypes and the capacity to partition energy into competing life history traits. Such relationships could be predictive of individual phenotypic performances throughout life. Here, we were specifically interested in whether an individual

Torpor, the temporary reduction of metabolic rate and body temperature, is a common energy-saving strategy in endotherms. Because of their small body size and energetically demanding life histories, hummingbirds have proven useful for understanding when and why endotherms use torpor. Previous studies of torpor in hummingbirds have been largely limited to tropical montane species or long-distance migrants

The Physiological Costs of Reproduction in a Capital Breeding Fish Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-12-09 Kim Birnie-Gauvin, Carsten Berthelsen, Torben Larsen, Kim Aarestrup
Reproduction represents the most energetically demanding period of life for many organisms. Capital breeders, such as anadromous sea trout (Salmo trutta), provide a particularly interesting group of organisms to study within the context of reproduction because they rely on energy stores accrued before breeding to reproduce and sustain all phenotypic and behavioral changes related to reproduction. Energy

Sex-Specific Effects of Blood Serotonin on Reproductive Effort in a Small Passerine Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-11-28 Vallo Tilgar

Serotonin could also help to understand intraspecific variation in reproductive strategies, although the mechanisms are poorly understood. In this study, the relationships of plasma serotonin with breeding parameters and parental behavior were

Flexible Employment of Torpor in Squirrel Gliders (Petaurus norfolcensis): An Adaptation to Unpredictable Climate? Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-11-21 Kathrin H. Dausmann, Gerhard Körtner, Yaara Aharon-Rotman, Shannon E. Currie, Fritz Geiser
Torpor is a highly effective response to counter various ecological and physiological bottlenecks in endotherms. In this study, we examined interrelations between thermoregulatory responses and key environmental variables in free-living squirrel gliders (Petaurus norfolcensis) in a habitat with drastic climatic and ecological changes across seasons. To this end, we measured body temperature (Tb) and

The Inverse Krogh Principle: All Organisms Are Worthy of Study Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-11-08 Christopher J. Clark, John R. Hutchinson, Theodore Garland
Krogh’s principle states, “For such a large number of problems there will be some animal of choice, or a few such animals, on which it can be most conveniently studied.” The downside of picking a question first and then finding an ideal organism on which to study it is that it will inevitably leave many organisms neglected. Here, we promote the inverse Krogh principle: all organisms are worthy of study

Mitigating Apoptotic and Inflammatory Signaling via Global Caspase Inhibition in Hibernating Ground Squirrels, Spermophilus lateralis Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-11-04 Michael D. Treat, Anthony J. Marlon, Lorena Samentar, Nora Caberoy, Frank van Breukelen
In most systems, the caspase cascade is activated during cellular stress and results in inflammation and apoptosis. Hibernators experience stressors such as extremely low body temperatures, bradycardia, possible ischemia and reperfusion, and acidosis. However, widespread inflammation and apoptosis would represent an energetic expense that is incompatible with hibernation. To better understand global

Divergent Pathways of Ammonia and Urea Production and Excretion during the Life Cycle of the Sea Lamprey Physiol. Biochem. Zool.

Vijayan, Michael P. Wilkie
Little is known about nitrogenous waste (N waste) handling and excretion (JN waste) during the complex life cycle of the sea lamprey (Petromyzon marinus), an extant jawless fish that undergoes a complete metamorphosis from a filter-feeding larva (ammocoete) into a parasitic juvenile that feeds on the blood of larger, jawed fishes. Here, we investigate the ammonia- and urea-handling profiles of sea

Altricial Bird Early-Stage Embryos Express the Molecular “Machinery” to Respond to and Modulate Maternal Thyroid Hormone Cues Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-10-14 Suvi Ruuskanen, Mikaela Hukkanen, Natacha Garcin, Nina Cossin-Sevrin, Bin-Yan Hsu, Antoine Stier
Maternal hormones, such as thyroid hormones (THs) transferred to embryos and eggs, are key signaling pathways for mediating maternal effects. To be able to respond to maternal cues, embryos must express the key molecular “machinery” of hormone pathways, such as enzymes and receptors. While altricial birds begin TH production only at or after hatching, experimental evidence suggests that their phenotype

PUFA Changes in White Adipose Tissue during Hibernation in Common Hamsters Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-09-30 Carina Siutz, Matthias Nemeth, Ruth Quint, Karl-Heinz Wagner, Eva Millesi
Hibernators save energy during winter by expressing torpor bouts characterized by strongly reduced body temperature and metabolic rate. Polyunsaturated fatty acids (PUFAs), specifically n-6 PUFAs, are known to positively affect hibernation performance and thereby energy savings predominantly in fat-storing hibernators. Accordingly, hibernators usually retain PUFAs and mobilize monounsaturated fatty

Variation in Melanin Content of Lizard Livers: Hybrids Turning to the Dark Side Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-09-30 Victoria Del Gaizo Moore, Gregory J. Haenel
Pigments such as melanin are most often associated with the surface of an organism, providing functions such as coloration and protection from UV radiation. However, the internal organs of some species also contain melanin. Internal melanin may also perform protective functions when cellular stress is experienced. We tested liver tissue of two tree lizard species that experienced introgression of their

A Standardized Protocol for Measuring Bioelectrical Impedance in Green Turtles (Chelonia mydas) Physiol. Biochem. Zool. (IF 1.6) Pub Date : 2022-09-23 Sara Kophamel, Leigh C. Ward, Ellen Ariel, Diana Mendez, Lauren M. O’Brien, Lauren Burchell, Suzanne L. Munns
Bioelectrical impedance analysis (BIA) is gaining popularity in wildlife studies as a portable technology for immediate and nondestructive predictions of body composition components, such as fat-free and fat masses. Successful application of BIA for field-based research requires the identification and control of potential sources of error, as well as the creation of and adherence to a standardized
