Through a selection of her stunning photographs, Alexandra Morton
portrays life on the central British Columbia coast.She arrived in
the area in 1984 as a whale researcher, and at first, she was
absorbed in studying the orca and admiring the magnificent scenery.
It is a coast with a long history: dolphins have pulsed in and out
for 10,000 years; First Nations people have lived here for almost
as long; European settlers arrived a scant century ago. As time
passed, Morton began to observe the lives of other creatures that
share the sea and land-humpback whales, bears, salmon, eagles,
deer, and humans-and understand how they are all interconnected. As
one example, "Bears drag salmon beneath the trees of the forest,
feeding the giant plants that shade the river nursery, protect its
banks and allow it to make more fish." In "Beyond the Whales,"
Alexandra explains what is going on beyond the beauty of the
images: "One of the joys of watching a place for 20 years is being
able to read the signs upon the sea-bubbles on the surface mean
tons of herring below; three birds over an orca mean the whale has
brought fish to the surface; shearwaters in Blackfish Sound mean
autumn is here. The ocean feeds the rivers and the rivers feed the
ocean."
"Rodent Societies "synthesizes and integrates the current state of
knowledge about the social behavior of rodents, providing
ecological and evolutionary contexts for understanding their
societies and highlighting emerging conservation and management
strategies to preserve them. It begins with a summary of the
evolution, phylogeny, and biogeography of social and nonsocial
rodents, providing a historical basis for comparative analyses.
Subsequent sections focus on group-living rodents and characterize
their reproductive behaviors, life histories and population
ecology, genetics, neuroendocrine mechanisms, behavioral
development, cognitive processes, communication mechanisms,
cooperative and uncooperative behaviors, antipredator strategies,
comparative socioecology, diseases, and conservation. Using the
highly diverse and well-studied Rodentia as model systems to
integrate a variety of research approaches and evolutionary theory
into a unifying framework, "Rodent Societies "will appeal to a wide
range of disciplines, both as a compendium of current research and
as a stimulus for future collaborative and interdisciplinary
investigations.

This book presents five chapters describing the characteristics and
behaviors of Bubalus bubalis, or domestic water buffalo. Chapter
One provides an update on recent developments in the approaches for
estrus detection in buffalo. Chapter Two explains the pelvimetry of
the female buffalo reproductive system and the biometry of the
reproductive system of male and female buffaloes. Chapter Three
assesses the effect of slow-release subcutaneous exogenous
melatonin implant on hematological profiles, endocrinological
profiles, biochemical profiles and antioxidant and oxidative stress
profiles in anestrus buffalo cows during the summer season to
improve reproductive efficiency. Chapter Four consists of a study
of Andaman local buffaloes that may serve as the reference values
in which alterations due to metabolic, nutrient deficiency,
physiological and health status can be compared for diagnostic and
therapeutic purposes. Lastly, Chapter Five focuses mainly on the
impact of heat stress on buffalo's behavior, physiology,
metabolism, and acclimatization.
