The functional microclimate of an urban arthropod pest: Urban heat island temperatures in webs of the western black widow spider J. Therm. Biol. (IF 2.7) Pub Date : 2024-02-22 Ryan C. Clark, J. Chadwick Johnson
Urbanization alters natural landscapes and creates unique challenges for urban wildlife. Similarly, the Urban Heat Island (UHI) effect can produce significantly elevated temperatures in urban areas, and we have a relatively poor understanding of how this will impact urban biodiversity. In particular, most studies quantify the UHI using broad-scale climate data rather than assessing microclimate temperatures

Individual variation in energetics, environment, and genetics can influence population-level processes. However, it is often assumed that locally measured thermal and bioenergetic responses apply among broadly related species. Even closely related taxa may differ in the thermal sensitivity of performance, which in turn influences population persistence, population vital rates, and the ability to respond

Chill susceptible insects are thought to be injured through different mechanisms depending on the duration and severity of chilling. While chronic chilling causes “indirect” injury through disruption of metabolic and ion homeostasis, acute chilling is suspected to cause “direct” injury, in part through phase transitions of cell membrane lipids. Dietary supplementation of cholesterol can reduce acute

Skeletal muscle is a highly plastic tissue. The role of heat shock protein 72 (Hsp72) in heat stress-induced skeletal muscle hypertrophy has been well demonstrated; however, the precise mechanisms remain unclear.

Nightly reductions in body temperature and effect of transmitter attachment method in free-living welcome swallows (Hirundo neoxena) J. Therm. Biol. (IF 2.7) Pub Date : 2024-01-28 Alice Barratt, Christopher Turbill
Small birds and mammals can face similar energetic challenges, yet use of torpor to conserve energy while resting is considered less common among birds, especially within the most specious order Passeriformes. We conducted the first study to record the natural thermoregulatory physiology of any species from the family Hirundinidae, which we predict to use torpor because of their specialised foraging

Elevational variation in metabolic rate, feeding capacity and their associations in the Asiatic toad Bufo gargarizans J. Therm. Biol. (IF 2.7) Pub Date : 2024-01-26 Yuechan Zhang, Song Tan, Jinzhong Fu, Jingfeng Chen
Foraging behavior is known to place demands on the metabolic characteristics of anurans. Active foragers feeding on sedentary prey typically have high aerobic capacity and low anaerobic capacity, whereas sit-and-wait foragers feeding on active and mobile prey have the opposite pattern. Thus, the energetic demands of foraging may influence their metabolic adaptations to harsh environments, such as high

As traditionally cold areas become warmer due to climate change, temperature could no longer be a barrier to the establishment of non-native insects. This is particularly relevant for pest insects from warm and tropical areas, mainly those with some tolerance to moderately low temperatures, which could expand their range into these new locations. From this perspective, in this work we studied the morphological

Geography and developmental plasticity shape post-larval thermal tolerance in the golden star tunicate, Botryllus schlosseri J. Therm. Biol. (IF 2.7) Pub Date : 2023-12-05 Zachary Tobias, Andrew Solow, Carolyn Tepolt
Local adaptation and phenotypic plasticity play key roles in mediating organisms’ ability to respond to spatiotemporal variation in temperature. These two processes often act together to generate latitudinal or elevational clines in acute temperature tolerance. Phenotypic plasticity is also subject to local adaptation, with the expectation that populations inhabiting more variable environments should

3D printed models are an accurate, cost-effective, and reproducible tool for quantifying terrestrial thermal environments J. Therm. Biol. (IF 2.7) Pub Date : 2023-12-04 Karla Alujević, Leah A. Bakewell, Ian T. Clifton, Christian L. Cox, Luke O. Frishkoff, Eric J. Gangloff, Guillermo Garcia-Costoya, Matthew E. Gifford, Madison Glenwinkel, Samir A.K. Gulati, Alyssa Head, Monica Miles, Ciara Pettit, Charles M. Watson, Kelly L. Wuthrich, Michael L. Logan
Predicting ecological responses to rapid environmental change has become one of the greatest challenges of modern biology. One of the major hurdles in forecasting these responses is accurately quantifying the thermal environments that organisms experience. The distribution of temperatures available within an organism's habitat is typically measured using data loggers called operative temperature models

In vivo heat production dynamics during a contraction-relaxation cycle in rat single skeletal muscle fibers J. Therm. Biol. (IF 2.7) Pub Date : 2023-11-30 Ayaka Tabuchi, Yoshinori Tanaka, Hiroshi Horikawa, Takuto Tazawa, David C. Poole, Yutaka Kano
Skeletal muscle generates heat via contraction-dependent (shivering) and independent (nonshivering) mechanisms. While this thermogenic capacity of skeletal muscle undoubtedly contributes to the body temperature homeostasis of animals and impacts various cellular functions, the intracellular temperature and its dynamics in skeletal muscle in vivo remain elusive. We aimed to determine the intracellular

Rectal and gastrointestinal temperature differ during passive heating and subsequent recovery J. Therm. Biol. (IF 2.7) Pub Date : 2023-12-04 Thomas J. O'Brien, Victoria L. Goosey-Tolfrey, Christof A. Leicht
We aimed to compare rectal temperature (Trec) and gastro-intestinal temperature (TGI) during passive heating and subsequent recovery with and without ice slurry ingestion. Twelve males (age: 25 ± 4 years, body mass index: 25.7 ± 2.5 kg m−2) were immersed in hot water on two occasions (Trec elevation: 1.82 ± 0.08°C). In the subsequent 60-min recovery in ambient conditions, participants ingested either

Comparing thermoregulatory responses between short and long moderate intensity intermittent exercise protocols with the same duty cycle J. Therm. Biol. (IF 2.7) Pub Date : 2023-11-29 Tze-Huan Lei, Chien Lin, Tatsuro Amano, Anna Ooue, Toby Mündel, James David Cotter, Naoto Fujii, Takeshi Nishiyasu, Narihiko Kondo
To date, the thermoregulatory response between continuous and intermittent exercise has been investigated whilst limited studies are available to examine the thermoregulatory response between different modes of intermittent exercises. We sought to determine the effect of two patterns of short duration intermittent exercises (180:180 (3-min) and 30:30 s (30-s) work: rest) on thermoregulatory responses

Exploring the impact of heat stress on oocyte maturation and embryo development in dairy cattle using a culture medium supplemented with vitamins E, C, and coenzyme Q10 J. Therm. Biol. (IF 2.7) Pub Date : 2023-11-25 Aref Maddahi, Adel Saberivand, Hossein Hamali, Farnoosh Jafarpour, Maryam Saberivand
Heat stress is a significant factor affecting the fertility of dairy cattle due to the generation of free radicals. In assisted reproductive techniques, the inclusion of protective antioxidants becomes crucial to mitigate potential cellular damage. This study aimed to explore the impact of supplementing vitamins E, C, and coenzyme Q10 into the oocyte culture medium, with the goal of ameliorating the

Assessing the effects of oxytocin in changes of core body temperature during LPS-induced endotoxemia: A novel approach using Extended Poincaré Plot Analysis J. Therm. Biol. (IF 2.7) Pub Date : 2023-11-30 Óscar Javier López-Troncoso, José Javier Reyes-Lagos, Martin Hadamitzky, Miguel Ángel Peña-Castillo, Juan Carlos Echeverría, Laura Lückemann, Manfred Schedlowski, Gustavo Pacheco-López
Oxytocin has shown cardioprotective effects during inflammation and may modify the core body temperature changes in LPS-induced endotoxemia. Notably, the time series analysis of core body temperature fluctuations may indicate thermoregulation alterations. This study aims to assess the effects of oxytocin on changes in the core body temperature by analyzing the fluctuations of the temperature time series
