“…In our study, glucose was significantly lower in the F2F group, and this may due to the increased locomotion of F2F respect to the other two groups. Probably for the same reason, lactate was significantly higher in F2F group, but such result is in contrast with several authors who reported a usual linear correlation between the glucose and lactate increases [30,31]. Additionally, similarly to cortisol, no differences were seen for PCV.…”

The aim of this research was to evaluate the possible usefulness of mirrors in improving rabbit behavior in a free-range breeding system. Three groups (each consisting of nine replicates of three animals) were compared: isolated, isolated with mirrors and separated by a wire mesh (possible visual and olfactory contacts). Rabbits allowed to have a visual and olfactory contact showed a significantly higher expression of important natural behaviors (olfactory investigation, gnawing, alertness, stretching, locomotion) compared to the isolated rabbits (with or without mirrors); while rabbits in the mirror group showed higher allo-grooming activity than those isolated and no different locomotion activity than those separated by wire mesh. Thus, mirrors seemed to be able to modify the behavioral repertoire of isolated rabbits by acting on social perception in rabbits reared in small groups in a free-range system. Nevertheless, despite it being advisable to use a combination of different indicators in order to assess the stress level of an animal, the accuracy of serum cortisol, as well as of some secondary stress markers assay, appeared to be limited in this type of breeding.

“…20 Rectal temperature, glucose and lactate concentrations, and PCV are also found to increase immediately after transport. 3 In both reports, these physiologic changes returned to normal within 48 h. 3,20 Because our project was designed to test the effects of MMW on rabbits, stressful procedures such as blood collection were avoided whenever possible. Examinations of the rabbits prior exposure to MMW confirmed that the frequency of animals with abnormal eye conditions was below reasonable levels (data not shown).…”

Millimeter waves (MMW) have broad applications in highdata-rate communication systems (40 to 48 GHz), automotive radar sensors (77 GHz), high-resolution sensors for airport security (100 GHz), and spectroscopy (20 to 80 GHz). 4,6,14,21 Moreover, the recent trend in wireless communications is to use MMW with frequencies greater than 100 GHz (>100 GHz MMW) to transfer larger amounts of digital data. 1 The rapid development of technology has raised concerns about the possible influence of MMW on human health. We previously investigated elevations in ocular temperature after the exposure of Dutch-belted rabbit eyes to quasi-and millimeter waves (18 to 40 GHz) and acute ocular damage caused by 40 to 95 GHz MMW. 9-11 We found that exposure to MMW induced a rapid elevation in ocular temperature, causing various types and levels of thermal injury. 9-11 MMW at frequencies exceeding 100 GHz are speculated have different thermal damage thresholds. 8 However, few scientific data regarding the effects of >100 GHz MMW on eyes are available. Acute ocular damage induced by >100 GHz MMW is difficult to determine because of limitations in generating sufficient output power to cause acute thermal effects. We, therefore, used gyrotrons at the Research Center for Development of Far-infrared Region (University of Fukui, Japan), which can generate MMW at frequencies ranging from 162 to 265 GHz, with a maximum output power exceeding 1 kW. 19 Because the gyrotron system is composed of large and immobile equipment, the rabbits had to be brought to the gyrotron facility to perform experiments. However, no laboratory animal facility for rabbits was available at that site, with the nearest one being 6.3 miles away at another UF campus. Because rabbits are prone to transportation stress, it was vital to keep them on-site during research. 18 It was not possible to build a new animal facility for this project alone. Therefore, an alternative housing system was needed that provided a stable and adequate environment for laboratory rabbits, was easy to set up for a short period (1 wk), and was affordable. This study describes the creation of a stable and adequate environment for laboratory rabbits at the gyrotron facility that allowed the performance of reliable and reproducible animal tests. A suitable environment was created in a cargo van rented from a local agency, without changing the original configuration of the vehicle. Environmental factors were monitored to ensure that they met the criteria for conventional animal facilities. The adaptation period required by the laboratory rabbits was also assessed.

“…By now, numerous studies have shown that Galen's "ephemeral fever" is not just restricted to humans. Instead, many rodent, non-hominid primate, and even bird species appear to change their body temperatures after exposure to common disturbances, such as transportation or restraint 5,6,7 .…”

Endotherms trade body temperature regulation for the stress response

In response to stressors, many species limit reproduction, reduce investment in immunity, and even forgo somatic repair to free energy for use toward coping. Often, however, the energetic costs of simply regulating body temperature can exceed those required for each of these processes, yet whether thermoregulation is also eschewed in response to stressors is not known. In this study, we used a phylogenetically-controlled meta-regression to test whether changes in body temperature that accompany the stress response - a common phenomenon among terrestrial vertebrates - represent the outcome of an energy allocation trade-off between thermoregulation and responding to stressors in these species. Our results, obtained from 65 studies and across 24 species, support this trade-off hypothesis by showing that body temperatures tended to drift toward ambient following stress exposures, but particularly in species with high costs of thermoregulation and little energy available for use (i.e those with low body mass and high resting metabolism respectively). These cross-species findings indicate that terrestrial endotherms may trade-off investment toward thermoregulation for that toward the stress response. With such findings in mind, evaluating how these endotherms may cope with warming climates and concurrent stressors should be key priority in the coming decade.
