Excerpt: The science of zoology is expanding at such a rate that it is difficult for even the relatively narrow specialist to keep up with the ever- increasing literature on his subject, and almost impossible to assimilate recent findings in the entire field of zoological research. The international congresses of zoology and entomology have helped, considerably by facilitating personal contact between workers of different nationalities. On a more modest scale, the symposia of the Royal Entomological Society of London have provided a useful means of bringing together entomologists in an atmosphere conducive to the free exchange of ideas and information

Chapter II-2 - Edward S. Morse grows up

In which teenage Edward S. Morse of Salem, Massachusetts, begins a life-long love affair with shells, leaves home for Boston, studies with Louis Agassiz at the Museum of Comparative Zoology in Cambridge, and becomes the world's leading authority on brachiopods (by proving conclusively that these tiny creatures are not mollusks, but worms), and how these same brachiopods lead him, at the age of thirty-nine, to Japan

\u3ci\u3eForficula Auricularia\u3c/i\u3e L. (Dermaptera: Forficulidae) in Michigan

(excerpt) Although Forficula auricularia Linnaeus, the European Earwig, has been known to occur in Ontario, Canada since prior to 1937 (Vickery and Kevan, 1967), invasion of Michigan by this species is of more recent date. A specimen in the University of Michigan Museum of Zoology was taken at Lansing in 1948 and, judging from specimens at hand, the species was fairly common there by 1964. In 1966, Thomas E. Moore, of the Museum of Zoology, took a number of specimens at Beulah in Benzie County and informed me that the earwig was rather abundant on common milkweed. Since that time there appears to have been an explosive build up of populations in the northwestern part of the state. Auricularia is reported as occurring in great numbers around Benzonia, Benzie County and in Charlevoix, Charlevoix County where they have been observed in numbers approaching tens of thousands. I have also seen specimens from Missaukee County, Harbor Springs in Emmet County, Alpena in Alpena County, and Detroit, Wayne County. An undocumented report indicates that the species was observed in 1971 in large numbers at Big Rapids, Mecosta County

Introduction to Zoology. T. H. Savory. New York: Philosophical Library, 1968. viii, 239 pp. $6.00.

Excerpt: This book would delight the traditional zoologist as its emphasis is on systematics and evolution. primarily based on morphology. By the author\u27s own admission he neglects areas concerning histology, embryology, physiology and genetics, while giving little time to areas he terms animal biology--symbiosis, parthenogenesis, behavior and parasitism. Dr. Savory feels the aforementioned areas warrant volumes of their own. Yet this book is titled Introduction to Zoology. Perhaps a better title would be Introduction to Zoology, Part I. Systematics and Evolution

Two examples of non strictly convex large deviations

We present two examples of a large deviations principle where the rate function is not strictly convex. This is motivated by a model used in mathematical finance (the Heston model), and adds a new item to the zoology of non strictly convex large deviations. For one of these examples, we show that the rate function of the Cramer-type of large deviations coincides with that of the Freidlin-Wentzell when contraction principles are applied.Comment: 11 page

Zoology of instanton solutions in flat potential barriers

We perform a detailed study of the existence and the properties of O(4)-invariant instanton solutions in Einstein-scalar theory in the presence of flat potential barriers, i.e. barriers where the second derivative of the potential is small at the top of the barrier. We find a whole zoo of solutions: Hawking-Moss, Coleman-De Luccia (CdL), oscillating instantons, asymmetric CdL as well as other non-standard CdL-like solutions with additional negative modes in their spectrum of fluctuations. Our work shows how these different branches of solutions are connected to each other via "critical" instantons possessing an extra zero mode fluctuation. Overall, the space of finite action euclidean solutions to these theories with flat barriers is surprisingly rich and intricate.Comment: 22 pages, 11 figure
