“…Low temperatures during pupal development may impair learning and cause significant differences in the behaviour of adult bees . Colony temperature also affects the basal metabolism of hive bees (Stabentheiner et al, 2003a;Kovac et al, 2007). Social thermoregulation allows for overwintering of colonies in cold climates (Stabentheiner et al, 2003b).…”

“…Its great advantage is that the bees are supplied with fresh air throughout the experiment, which makes possible measurements over extended time periods (Kovac and Stabentheiner, 2007). If necessary, the atmospheric composition may be changed artificially, for example to investigate the impact of tracheal mites on flight capability (Harrison et al, 2001) (2008) and Lighton and Halsey (2011).…”

SummaryDespite their tremendous economic importance, and apart from certain topics in the field of neurophysiology such as vision, olfaction, learning and memory, honey bees are not a typical model system for studying general questions of insect physiology. The reason is their social lifestyle, which sets them apart from a "typical insect" and, during social evolution, has resulted in the restructuring of certain physiological pathways and biochemical characteristics in this insect. Not surprisingly, the questions that have attracted most attention by researchers working on honey bee physiology and biochemistry in general are core topics specifically related to social organization, such as caste development, reproductive division of labour and polyethism within the worker caste. With certain proteins playing key roles in these processes, such as the major royal jelly proteins (MRJPs), including royalactin and hexamerins in caste development, and vitellogenin in reproductive division of labour and age polyethism, a major section herein will present and discuss basic laboratory protocols for protein analyses established and standardized to address such questions in bees. A second major topic concerns endocrine mechanisms underlying processes of queen and worker development, as well as reproduction and polyethism, especially the roles of juvenile hormone and ecdysteroids. Sensitive techniques for the quantification of juvenile hormone levels circulating in haemolymph, as well as its synthesis by the corpora allata are described. Although these require certain instrumentation and a considerable degree of sophistication in the analysis procedures, we considered that presenting these techniques would be of interest to laboratories planning to specialize in such analyses. Since biogenic amines are both neurotransmitters and regulators of endocrine glands, we also present a standard method for the detection and analysis of certain biogenic amines of interest. Further questions that cross borders between individual and social physiology are related to energy metabolism and thermoregulation. Thus a further three sections are dedicated to protocols on carbohydrate quantification in body fluid, body temperature measurement and respirometry.

Life originated in anoxia, but many organisms came to depend upon oxygen for survival, independently evolving diverse respiratory systems for acquiring oxygen from the environment. Ambient oxygen tension (PO2) fluctuated through the ages in correlation with biodiversity and body size, enabling organisms to migrate from water to land and air and sometimes in the opposite direction. Habitat expansion compels the use of different gas exchangers, for example, skin, gills, tracheae, lungs, and their intermediate stages, that may coexist within the same species; coexistence may be temporally disjunct (e.g., larval gills vs. adult lungs) or simultaneous (e.g., skin, gills, and lungs in some salamanders). Disparate systems exhibit similar directions of adaptation: toward larger diffusion interfaces, thinner barriers, finer dynamic regulation, and reduced cost of breathing. Efficient respiratory gas exchange, coupled to downstream convective and diffusive resistances, comprise the “oxygen cascade”—step-down of PO2 that balances supply against toxicity. Here, we review the origin of oxygen homeostasis, a primal selection factor for all respiratory systems, which in turn function as gatekeepers of the cascade. Within an organism's lifespan, the respiratory apparatus adapts in various ways to upregulate oxygen uptake in hypoxia and restrict uptake in hyperoxia. In an evolutionary context, certain species also become adapted to environmental conditions or habitual organismic demands. We, therefore, survey the comparative anatomy and physiology of respiratory systems from invertebrates to vertebrates, water to air breathers, and terrestrial to aerial inhabitants. Through the evolutionary directions and variety of gas exchangers, their shared features and individual compromises may be appreciated.

Nasal airflow and thoracoabdominal motion in children using infrared thermographic video processing

The assessment of apnea and asynchronous breathing requires the application of a facemask connected to a pneumotachograph and inductive transducer bands placed around the chest wall. These contact devices may alter the breathing pattern and are difficult to implement, especially in infants and children. This study validates a contactless image-processing system that simultaneously retrieves breath-related thermal variations from nasal, ribcage, and abdomen regions of interest (ROI) from infrared thermographic video recordings of children. Thermographic videos were obtained in 17 supine, spontaneously breathing unsedated children (0.33-13.75 years), including 8 patients with respiratory pathology. Representative thermographic signals were obtained from each ROI on a frame-by-frame basis. Cronbach's Alpha reliability coefficient assessed the correlation between control nasal pressure period, the visually scored respiratory rate and the fundamental period in the frequency domain of thermographic signals. A cross-correlation function calculated the time delay and the phase angle between ribcage and abdomen variability. A Cronbach's Alpha value of 0.976 (0.992-0.944 95% CI) suggests a small-scale measurement error between thermographic and control periods. The ribcage-abdomen time delay in children with respiratory disease (-0.42 ± 0.707 sec) significantly differed from healthy children (0.22 ± 0.426 sec, P = 0.0125). This novel system reliably acquired time-aligned nasal airflow and thoracoabdominal motion estimates without relying on attached sensor performance and detected asynchronous breathing in pediatric patients.
