The most comprehensive reference guide to mammal tracks and sign for North America. This new edition is more visual, with more than 1300 photos and 450 illustrations for easy comparison and identification of similar sign. Each species account includes information on tracks and trails, scat and urine, nests and lodges, as well as sign on the ground, in trees and shrubs, on fungi and on plants. Winner of the 2019 National Outdoor Book Award for Outdoor Classic Books.

Ranging from the largest terrestrial carnivore, the Polar Bear, to the tiny Least Weasel that can squeeze through a wedding ring, the true carnivores include some of the world's most charismatic, admired, feared and spectacular creatures. This new edition of Luke Hunter's comprehensive guide profiles all of the world's terrestrial carnivore species. Thoroughly updated throughout and covering recently described species, a detailed account describes each species' key identification characteristics, distribution and habitat, behaviour, feeding ecology, social patterns, life history statistics, conservation and the latest on classification. The new edition also includes accurate distribution maps for each species. Colour plates by top wildlife artist Priscilla Barrett depict each species, with subspecies, colour variations and behavioural vignettes for many. There are also detailed line drawings of more than 230 skulls and 110 footprints.

The origin of the human mind remains one of the greatest mysteries of all times. The last 150 years since Charles Darwin proposed that species evolve under the influence of natural selection have been marked by great discoveries. However, the discussion of the evolution of the human intellect and specific forces that shaped the underlying brain evolution is as vigorous today as it was in Darwin's times. Using his background in neuroscience, the author offers an elegant, parsimonious theory of the evolution of the human mind and suggests experiments that could be done to test, refute, or validate the hypothesis. The basis of the theory is a simple, yet fundamental question: what happens neurologically when two objects, never before seen together (say, an apple on top of a whale), are imagined together for the first time. The scientific consensus is that a familiar object, such as an apple or a whale, is represented in the brain by thousands of neurons dispersed throughout the posterior cortex. When one sees or recalls such an object, the neurons of that object’s neuronal ensemble tend to activate into synchronous resonant activity. The neuronal ensemble binding mechanism, based on the Hebbian principle “neurons that fire together, wire together,” came to be known as the binding-by-synchrony hypothesis. However, while the Hebbian principle explains how we perceive a familiar object, it does not explain the infinite number of novel objects that humans can voluntarily imagine. The neuronal ensembles encoding those objects cannot jump into spontaneous synchronized activity on their own since the parts forming those novel images have never been seen together. The author argues that to account for imagination, the binding-by-synchrony hypothesis would need to be extended to include the phenomenon of mental synthesis whereby the brain actively and intentionally synchronizes independent neuronal ensembles into one morphed image. Thus, the apple neuronal ensemble is synchronized with the whale neuronal ensemble, and the two disparate objects are perceived together. The synchronization mechanism of mental synthesis is likely responsible for many imaginative and creative traits that scientists have recognized as being uniquely human, despite not having a precise neurological understanding of the process. How did humans acquire mental synthesis? As of 100,000 years ago, hominins had already evolved both a greater control of perception by the prefrontal cortex and a nearly modern speech-production apparatus. However the connections between the prefrontal cortex and the posterior cortex remained asynchronous; the prefrontal cortex was unable to synchronize independent neuronal ensembles, speech remained finite and non-syntactic: one word was only able to communicate one image. At that time, a single mutation delayed the ontogenetic development of the prefrontal cortex and permitted the newly invented syntactic speech to train the synchronous connections between the prefrontal cortex and the posterior cortex. This allowed the acquisition of mental synthesis and propelled humans to behavioral modernity. These behaviorally modern humans excelled at performing mental simulations, which resulted in the dramatic acceleration of technological progress; the human population exploded and humans quickly settled most habitable areas of the planet. Armed with the ability to mentally simulate any plan and then to communicate it to their companions, humans rapidly became the dominant species.

The book examines the issues of sustainability in general. It addresses various socioeconomic determinants of ecological footprints in different world’s nations, regions, and cultures. Major socioeconomic determinants of ecological footprints are fleshed out using Comparative Model Analysis and rigorous Multiple Regression Analysis. The study exposes the inequitable distribution of the world’s ecological footprints and also heightens the concern about ecological imbalances and overshoots. It explains how sustainable development can be promoted and achieved in regional, national, and local jurisdictions. The study provides information that will likely help various governments and policy-makers determine if a given nation, region, or culture is on a sustainable path. It helps government leaders, planners, policy-makers, and even students of sustainability make a difference in mitigating the effects of various environmental stressors. If this book makes people and policy-makers in different countries, regions, and cultures think globally but act locally, then the objectives are well-served.

Gripping and dramatic, Yellow Footprints reveals the extraordinary journey of becoming one of the proud...and one of the few. Set in 1969 during the height of the Vietnam War, Yellow Footprints details the grueling training of Platoon 3074 to prepare them for the mighty ranks of the U.S. Marine Corps. From the harrowing first few days to the camaraderie forged by the men who shared this ordeal, author Jack Shipman presents an unrestrained look at boot camp not often viewed by the public. Yellow footprints mark the entrance to the Receiving Barracks at the U.S. Marine Corps Recruit Depot at Parris Island, South Carolina, and San Diego, California. Along with the other new recruits, Jack Shipman took his first steps on those footprints to either become a proud U.S. Marine or wash out of the toughest military training in the world. Shipman's attention to detail and his frank assessment of his experiences offers a highly readable account for those seeking to learn the fundamentals of Marine Corps history.
