Taxonomists specializing in different groups once based phylogenetic analysis only on morphological data; molecular data was used more rarely. Although…
molecular systematics is routine today, the use of morphological data continues to be important, especially for phylogenetic placement of many taxa known only from fossils and rare or difficult to collect species. In addition, morphological analyses help identify potential biases in molecular analyses. And finally, scenarios with respect to morphology continue to motivate biologists: the beauty of a cheetah or a baobab does not lie in their DNA sequence, but instead on what they are and do! This book is an up-to-date revision of methods and principles of phylogenetic analysis of morphological data. It is also a general guide for using the computer program TNT in the analysis of such data. The book covers the main aspects of phylogenetic analysis and general methods to compare classifications derived from molecules and morphology. The basic aspects of molecular analysis are covered only as needed to highlight the differences with methods and assumptions for analysis of morphological datasets.By Stephen J. Harper. 1912
Drawing on extensive archival records and illustrations, histories of the sport, and newspaper files, Canada’s Prime Minister delves into the…
fascinating early years of ice hockey.In the tumultuous beginnings of hockey, the fights were as much off the ice as on it. This engaging new book is about the hockey heroes and hard-boiled businessmen who built the game, and the rise and fall of legendary teams pursuing the Stanley Cup. With a historian’s perspective and fan’s passion, Stephen Harper presents a riveting and often-surprising portrait, capturing everything from the physical contests on the rinks to the battles behind the scenes.Stephen Harper shows that many things have stayed the same. Rough play, fervent hometown loyalties, owner-player contract disputes, dubious news coverage, and big money were issues from the get-go. Most important in these early years was the question: Was hockey to be a game of obsessed amateurs playing for the love of the sport, or was it a game for paid professionals who would give fans what they wanted? Who should be responsible for the sport—including its bouts of violence—both on and off the ice.A century ago, rinks could melt, and by halftime the blades screwed to the players’ shoes could be sinking in mud. It was during this time that the unsuccessful Toronto Professionals of 1908 and the victorious Toronto Blue Shirts of 1914 battled for the city’s very first Stanley Cup. Against the fanatical opposition of amateur hockey leaders, these “forgotten Leafs” would lay the groundwork for the world’s most profitable hockey franchise.In paying tribute to these hockey pioneers and the contagious loyalty of their fans, Harper resurrects the history of hockey’s first decades. Lavishly illustrated with photographs of the game’s greatest arenas and earliest star players, this entertaining and original book will captivate you from start to finish.By Federico Agnolin. 2024
The Cenozoic history of South America faunas mainly rests on the evidence yielded by the study of fossil mammals. Following…
the seminal work of William D. Matthew, George G. Simpson established the slogan “Splendid Isolation” for describing the evolutionary history of South American faunas. He envisaged South America (as well as other Southern Hemisphere landmasses) as dead ends in the evolution and geographical expansion of animals and plants that since the Mesozoic come in successive migratory waves from the North.More than 40 years passed away from the last important contribution by Simpson (1980). Since then, in spite to the exponential increase in biological, paleontological and geological knowledge, and an incredibly new number of fossils, his scheme remained almost unpolluted and most recent books regarding the palaeobiogeography of South American vertebrates follow this paradigm nearly without criticism.However, the factthat South America was joined to Africa, Australia, Antarctica and India during most of the Cretaceous, and that it was still connected Australia (via Antarctica) and probably Africa up to the Paleogene, together with the large number of shared biotic components between these landmasses, point in favor of a different paleobiogeographical scenario.The book aims to demonstrate that during the Paleogene (and most of the Neogene) the nature and evolutionary history of South American vertebrates is by far much more intricate than previously envisaged. As will be shown, new evidence suggests that southern landmasses may have played an important role in the early evolution and radiation of extant mammal clades. This book is not written to conform with the ideal of a technical manual or a review, and is not carried forward to collect all that has been said before. The main goals are to criticize the current Palaeobiogeographic Model of Vertebrate Settlement of South America, and to propose a new vision based on the evidence provided by the natural world in the last decades.By Lisa Randall. 2015

Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs.Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.By John Webb, Susan White, Garry K.

This book, part of the series Cave and Karst Systems of the World, begins with a review of the interaction…
between people and caves in Australia (including conservation), followed by descriptions of the spectacular cave diving sites, before comprehensively covering all the major carbonate and noncarbonate karst areas, subdivided by rock type and region, and including the origin of the caves. This is followed by broad overviews of cave minerals and speleothems, cave biology and cave fossils. Each section was written by one or more specialists in the topic and is illustrated by clear diagrams and superb colour photos. The book emphasises the unique aspects of the Australian karst, including the variability in the age of the caves (very old to very young) and the impact of isolation on the stygofauna, as well as the vertebrate fossils preserved in the caves. Written in an easy-to-read style, the book is a primary reference guide to Australian karst and represents a valuable asset for anyone interested in the topic, not only cavers and academics.By Michael Novacek. 2003
Hunting for fossils with a preeminent guide and teacherMichael Novacek, a world-renowned paleontologist who has discovered important fossils on virtually…
every continent, is an authority on patterns of evolution and on the relationships among extinct and extant organisms. Time Traveler is his captivating account of how his boyhood enthusiasm for dinosaurs became a lifelong commitment to vanguard science. He takes us with him as he discovers fossils in his own backyard in Los Angeles, then goes looking for them in the high Andes, the black volcanic mountains of Yemen, and the incredibly rich fossil badlands of the Gobi desert.Wherever Novacek goes he searches for still undiscovered evidence of what life was like on Earth millions of years ago. Along the way he has almost drowned, been stung by deadly scorpions, been held at gunpoint by a renegade army, and nearly choked in raging dust storms. Fieldwork is very demanding in a host of unusual, dramatic, sometimes hilarious ways, and Novacek writes of its alluring perils with affection and discernment. But Time Traveler also makes sense of many complex themes - about dinosaur evolution, continental drift, mass extinctions, new methods for understanding ancient environments, and the evolutionary secrets of DNA in fossil organisms. It is also an enthralling adventure story.
