Life at Small Scale
Our world is swarming with invisible organisms - bacteria and fungi that affect their hosts and environments in diverse ways. This text looks at the mysterious microscopic world of microbes and investigates how they behave, and why. It tells stories of how scientists have discovered the laws of behaviour of the world of microbes, including the principles of locomotion, navigation, survival, reproduction and communication. In addition, the text relates the behaviour of bacteria and other microbes to our more familiar world and shows their impact on our lives.
Living at Micro Scale
Kermit the Frog famously said that it isn’t easy being green, and in Living at Micro Scale David Dusenbery shows that it isn’t easy being small—existing at the size of, say, a rotifer, a tiny multicellular animal just at the boundary between the visible and the microscopic. “Imagine,” he writes, “stepping off a curb and waiting a week for your foot to hit the ground.” At that scale, we would be small enough to swim inside the letter O in the word “rotifer.” What are the physical consequences of life at this scale? How do such organisms move, identify prey and predators and (if they’re so inclined) mates, signal to one another, and orient themselves? In clear and engaging ...
Life at small scale
In Life at Small Scale, noted biophysicist David B. Dusenbery describes how microbes obtain and use information from their environments to meet the fundamental challenges all organisms face - getting food, avoiding predators and competitors, and dispersing progeny. As Dusenbery demonstrates, these organisms are hardly as simple as is often presumed. Despite their size (or rather because of it), microbes develop some surprisingly complex behaviors, all in response to the physical demands of the worlds they inhabit. Thus the pages of this captivating, richly illustrated volume are filled with descriptions of organisms that have devised remarkably sophisticated, often bizarre ways of moving, na...
Sensory Ecology
This book aims to define and establish the field of sensory ecology. Drawing knowledge from physics, microbiology, botany, animal behaviour and psychology, this landmark work provides a universal approach to understanding how organisms of all kinds obtain and use information about their environment. A seleciton of technical background and problems should stimulate ideas and experiments.

Ecology of Sensing
Sense organs serve as a kind of biological interface between the environment and the organism. Therefore, the relationship between sensory systems and ecology is very close and its knowledge of fundamental importance for an understanding of animal behavior. The sixteen chapters of this book exemplify the diversity of the constraints and opportunities associated with the sensation of stimuli representing different forms of energy. The book stresses the events taking place in the sensory periphery where the animal is exposed to and gets in touch with its natural habitat and acquires the information needed to organize its interaction with its environment. Ecology of Sensing brings together the leading experts in the field.
Sensors and Sensing in Biology and Engineering
Biological sensors are usually remarkably small, sensitive and efficient. It is highly desirable to design corresponding artificial sensors for scientific, industrial and commercial purposes. This book is designed to fill an urgent need for interdisciplinary exchange between biologists studying sensors in the natural world and engineers and physical scientists developing artificial sensors. The main topics cover mechanical sensors, e.g. waves and sounds, visual sensors and vision and chemosensors. Readers will obtain a fuller understanding of the nature and performance of natural sensors as well as enhanced appreciation for the current status and the potential applicability of artificial microsensors.
