Relationship between metabolic rate and blood perfusion under Fanger thermal comfort conditions.

J Therm Biol 2019 Feb 7;80:94-105. Epub 2019 Jan 7.

Faculty of Mechanical Engineering, University of Maribor, 2000, Slovenia.

The one-dimensional steady Pennes (bioheat) equation was applied to analyze heat conduction inside a combined layer of human muscle and fat, under Fanger thermal comfort conditions. The bioheat equation was solved subject to two boundary conditions at the skin surface: a prescribed skin temperature satisfying the Fanger comfort criterion, and a prescribed heat flux obtained from the overall energy balance for the system. In addition to a fixed body core temperature, an adiabatic condition was imposed as an auxiliary condition at the core of the body, and a pair of equations were derived, relating the blood perfusion and the volumetric heat generation rate for a given activity level and environmental conditions.

Ambient temperature preferences of chimney swifts (Chaetura pelagica) for Nest Site Selection.

J Therm Biol 2019 Feb 18;80:89-93. Epub 2018 Dec 18.

University of New Brunswick, 3 Bailey Drive, Fredericton, New Brunswick, Canada E3B 5A3.

Chimney swift (Chaetura pelagica) populations are declining rapidly, with no clear indication as to why. Reduced availability of nesting habitat (chimneys) was thought to be a limiting factor for this threatened species, but data from Ontario, Canada did not support this hypothesis. If availability is not limiting, then perhaps habitat quality may play a role. Read More

Effects of a broad range of experimental temperatures on the population growth and body-size of five species of free-living nematodes.

J Therm Biol 2019 Feb 15;80:21-36. Epub 2018 Dec 15.

EDF R&D LNHE - Laboratoire National d'Hydraulique et Environnement, Chatou, France.

The temperature-size rule postulates that the growth rates of ectotherms increase under rising temperatures, while the sizes of these organisms at maturity decrease. However, the upper temperature-tolerance range is also typically represented by a metabolic tipping point after which growth suddenly ceases. Free-living nematodes are important members of ecosystems, but little is known about their thermal tolerance. Read More

One way to understand ecological patterns of species is to determine their physiological diversity on a large geographic and/or temporal scales, in a context of hierarchical biodiversity framework. In particular, macrophysiological studies analyze how environmental factors affect the physiology and therefore the distribution of species. Subterranean species are an excellent model for evaluating the large-scale effects of ambient temperature (T) conditions on thermal physiology and distribution, due to their extensive use of burrows that provide a relatively thermal stable environment.

Exploring the human thermoneutral zone - A dynamic approach.

J Therm Biol 2019 Jan 18;79:199-208. Epub 2018 Dec 18.

Department of Human Biology and Movement Sciences, NUTRIM, Maastricht University, the Netherlands.

To date, the position and shape of the human thermoneutral zone (TNZ) remain uncertain. Indications exist that the individual TNZ might be influenced by age, body composition and level of acclimatisation. The objective of the present study was to explore the individual metabolic TNZ, using dynamic thermal conditions to assess both metabolic lower and upper critical temperatures (LCT and UCT) and, secondly, to test the effect of passive mild heat acclimation on the human metabolic TNZ.

Authors:
Radim Šumbera

J Therm Biol 2019 Jan 15;79:166-189. Epub 2018 Nov 15.

Department of Zoology, Faculty of Science, University of South Bohemia, Branišovská 1760, České Budějovice 37005, Czech Republic. Electronic address:

African mole-rats are subterranean rodents, which rarely if ever leave the safety of their burrow systems. The environment of the burrows is humid, with relatively stable temperatures, and may have a hypoxic and hypercapnic atmosphere. One of crucial problems related to the subterranean way of life in mammals is avoidance of overheating, because traditional mammalian cooling mechanisms are not effective under high humidity.

Temperature and depth profiles of Chinook salmon and the energetic costs of their long-distance homing migrations.

J Therm Biol 2019 Jan 11;79:155-165. Epub 2018 Dec 11.

Department of Fish and Wildlife Sciences, College of Natural Resources, University of Idaho, 875 Perimeter Drive MS 1136, Moscow, ID 83844-1136, USA.

River warming poses an existential threat to many Pacific salmon (Oncorhynchus spp) populations. However, temperature-mediated risks to salmon are often complex and addressing them requires species- and population-specific data collected over large spatial and temporal scales. In this study, we combined radiotelemetry with archival depth and temperature sensors to collect continuous thermal exposure histories of 21 adult spring- and summer-run Chinook salmon (O. Read More

The heat is on: A device that reduces cold stress-induced tachycardia in laboratory mice.

J Therm Biol 2019 Jan 13;79:149-154. Epub 2018 Dec 13.

Department of Biology, Williams College, Williamstown, MA 01267, USA. Electronic address:

Mouse vivaria are typically maintained at an ambient temperature (T) of 20-26 °C which is comfortable for human researchers. However, as this T is well below the mouse thermoneutral zone (TNZ) of 30-32 °C, typical vivarium temperatures result in cold stress for mice. Recently, a cage has been developed that provides variable cage floor heating, allowing mice to behaviorally regulate body temperature through thermotaxis. Read More

Interactions between thermoregulatory behavior and physiological acclimatization in a wild lizard population.

J Therm Biol 2019 Jan 11;79:135-143. Epub 2018 Dec 11.

Laboratorio de Herpetología 2, Departamento de Zoología, Instituto de Biología, Universidad Nacional Autónoma de México, Ciudad Universitaria, 04510 Coyoacán, Ciudad de México, México.

Although the importance of thermoregulation and plasticity as compensatory mechanisms for climate change has long been recognized, they have largely been studied independently. Thus, we know comparatively little about how they interact to shape physiological variation in natural populations. Here, we test the hypothesis that behavioral thermoregulation and thermal acclimatization interact to shape physiological phenotypes in a natural population of the diurnal lizard, Sceloporus torquatus.
