Physiological and Biochemical Zoology is a peer-reviewed scientific journal published by the University of Chicago Press on behalf of the Society for Integrative and Comparative Biology. PBZ presents current research on the biochemistry, physiology, and genetics of animals. PBZ focuses on the environment, ecology, and evolution of the organism -- from cellular mechanisms to whole animal adaptations, from protozoa to mammals, from eggs to larvae to adult organisms. According to the Instructions for Authors, PBZ publishes papers "about animal physiology and biochemistry at all levels of organization, from the molecular to the organismic, focusing on adaptations to the environment. The journal s specific emphasis is on studies that investigate the ecological and/or evolutionary aspects of physiological and biochemical mechanisms.
Salmon forced to 'sprint' less likely to survive migration
Sockeye salmon that sprint to spawning grounds through fast-moving waters may be at risk, suggests new research by University of British Columbia scientists.
Summertime cholesterol consumption key for wintertime survival for Siberian hamsters
Increasingly, scientific findings indicate that an organism's diet affects more than just general health and body condition. In an article published in a forthcoming issue of the journal Physiological an ...
Bluebirds struggle to find happiness on island paradise
Island plants and animals are often different from their mainland relatives. In general, the lack of top predators and large herbivores on isolated oceanic islands influences traits of island organisms. Consider, ...
Nature's glowing slime: Scientists peek into hidden sea worm's light
Scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues are unraveling the mechanisms behind a little-known marine worm that produces a dazzling bioluminescent display in the ...
Personality differences: In lean times red deer with dominant personalities pay a high price
Saving energy is important for humans and animals alike when resources are limited. Scientists at the Research Institute of Wildlife Ecology of the University of Veterinary Medicine, Vienna, found out that ...
Shifts in physiological mechanisms let male bats balance the need to feed and the urge to breed
A forthcoming article in Physiological and Biochemical Zoology reveals shifts in the mechanisms bats use to regulate metabolism throughout their seasonal activity period.
Why are there redheads? Birds might hold the clues
Red coloration—historically seen as costly in vertebrates—historically seen as costly in vertebrates—might represent some physiological benefit after all, according to research published in the journal Physiological an ...
Red hair is a sign of oxidative stress in wild boars, but gray is a-ok
A coat of a certain color could be costly for wild boars, according to research published in the journal Physiological and Biochemical Zoology.
Anxious mice make lousy dads: study
Normally, male California mice are surprisingly doting fathers, but new research published in the journal Physiological and Biochemical Zoology suggests that high anxiety can turn these good dads bad.
Brightly colored bird bills indicate good health
Troy Murphy has found female bill colour reflects the health of the bird. Females with more colourful bills have higher antibody levels, indicating greater strength and the ability to fight off invaders.
Why bigger animals aren't always faster (w/ Video)
New research in the journal Physiological and Biochemical Zoology shows why bigger isn't always better when it comes to sprinting speed.
Lizard moms may prepare their babies for a stressful world
Stressed out lizard moms tend to give their developing embryos short shrift, but the hardship may ultimately be a good thing for the babies once they're born, according to a study published in the journal ...
Energy requirements make Antarctic fur seal pups vulnerable to climate change
A new study suggests that climate change could pose a risk for Antarctic fur seals in their first few months of life.
