THE CONCEPT OF ALLOSTASIS: COPING WITH A CAPRICIOUS ENVIRONMENT
Abstract Vertebrates have regular patterns and routines that involve obtaining food and carrying out life-history stages such as breeding, migrating, molting, and hibernating. These are generally…

Excretion of Steroid Hormones in Rodents: An Overview on Species Differences for New Biomedical Animal Research Models
“environmental endocrinology” has developed in response to the need to understand how hormones modulate and control physiological processes in animals exposed to the exigencies of their particular natural environment.
Parasite ecology in spotted hyena in Serengeti National Park in Tanzania
It is revealed that age and co-infecting interactions are key factors of infection intensity of Ancylostoma spp.
Hormesis Against Aging and Diseases: Using Properties of Biological Adaptation for Health and Survival Improvement
- MedicineDose-response : a publication of International Hormesis Society
It is shown that redundancy in renewal capacity, some portion of which become activated and manifested in hormesis effects, may originate as a result of interaction between living organisms and their environment.
The application of allostasis and allostatic load in animal species: A scoping review
- BiologyPloS one
Although concepts of allostasis and allostatic load are being applied broadly across animal species, most publications use single biomarkers that are more likely indicative of short-term rather than chronic stress.
Physiological consequences of social descent: studies in Astatotilapia burtoni.
- BiologyThe Journal of endocrinology
The results suggest that in the short run, deposed T males essentially mount a neural 'defense' against loss of status, as they relate to short-term stress and the stress hormone cortisol.
Assessing the role of reproduction and stress in the spring emergence of haematozoan parasites in birds
- BiologyJournal of Experimental Biology
It is suggested that both seasonal increases in vector activity and relapse of latent (i.e. dormant) infections contribute to the spring emergence in birds.

ECOLOGICAL BASES OF HORMONE-BEHAVIOR INTERACTIONS : THE EMERGENCY LIFE HISTORY STAGE
Field work reveals that changes in responsiveness to LPFs have ecological bases, such as reproductive state, body condition etc., that in turn indicate different hormonal control mechanisms in the HPA cascade.
Allostasis and Allostatic Load: Implications for Neuropsychopharmacology
Human obesity: an evolutionary approach to understanding our bulging waistline
- MedicineDiabetes/metabolism research and reviews
The unique worldwide spread of the human species and the remarkably long post‐reproductive survival show that the authors' genome permits excellent adaptation to vastly different environments, and public health measures should be aggressively directed at the prevention of obesity from childhood.
Hormonal and Behavioral Responses to Food and Water Deprivation in a Lizard (Sceloporus occidentalis): Implications for Assessing Stress in a Natural Population
- Biology, Environmental Science
Western fence lizards, Sceloporus occidentalis, inhabiting the Mojave desert can face long periods of drought leading to dehydration and starvation. To examine behavioral and hormonal responses to…
Modulation of the Adrenocortical Responses to Acute Stress in Arctic Birds: A Possible Ecological Basis
- Biology, Environmental Science
Comparisons of the increases in plasma levels of corticosterone following capture in several taxa of arctic birds indicated that suppression of the adrenocortical response to acute stress was not ubiquitous, and comparative data from free-living arctic Birds suggest an ecological basis for modulation of the cortisol responses to stress.
Hormonal Alterations and Reproductive Inhibition in Male Fence Lizards (Sceloporus occidentalis) Infected with the Malarial Parasite Plasmodium mexicanum
- BiologyPhysiological Zoology
It is hypothesize that the parasite induces alterations in the adrenal response to acute stress, resulting in a suppression of testosterone and the inhibition of reproductive behavior, which is associated with hormonal alterations associated with malarial parasitism.
External and internal influences on indices of physiological stress: II. Seasonal and size-related variations in blood composition in free-living lizards, Sceloporus occidentalis.
- Environmental ScienceThe Journal of experimental zoology
Seasonal changes in blood composition in two free-living populations of fence lizards, Sceloporus occidentalis, one living in a very arid environment and another in a milder desert were analyzed and suggested that the physiological condition of the California population was affected by seasonal changes in the external environment.
Adrenocortical Response to Stress in the Common Diving Petrel, Pelecanoides urinatrix
- Biology, Environmental SciencePhysiological Zoology
Free-living common diving petrels, Pelecanoides urinatrix, captured at sea off South Georgia Island, showed highly significant elevations of circulating corticosterone levels after capture and handling stress, which suggests that these birds were already maximally stressed when captured.
Stress and the individual. Mechanisms leading to disease.
- MedicineArchives of internal medicine
A new formulation of the relationship between stress and the processes leading to disease is presented, emphasizing the cascading relationships between environmental factors and genetic predispositions that lead to large individual differences in susceptibility to stress and, in some cases, to disease.
Diabetes mellitus: a "thrifty" genotype rendered detrimental by "progress"?
- BiologyAmerican journal of human genetics
Current developments in the study of diabetes mellitus suggest an explanation with important biological ramifications, and changes in the environment are responsible for the increase.
