Ecology and Distribution of Diatoms from Boreal Forest Lakes in Wood Buffalo National Park, Northern Alberta and the Northwest Territories, Canada: Special Pub. No. 22 of the Acad. of Natural Sciences of Phila.
|
|
|
Diatoms were identified from the surface sediments of 35 small to intermediate-sized boreal forest lakes in Wood Buffalo Nat. Park, located on the border of Alberta and the NW Terr., Canada. A total of 276 diatom taxa were recorded; of these, 112 taxa, belonging to 29 genera, are illustrated. Detailed taxonomic descriptions and ecological info. are provided for 62 of these taxa. Striking differences in diatom assemblages were observed between the lakes sampled, which included 3 types: Shield lakes, situated in the granites and granitic gneisses of the Canadian Shield; sinkhole lakes, located in Palaeozoic-aged limestones and gypsums; and muskeg lakes, found in poorly drained areas characterized by Palaeozoic-aged calcareous shales.

|
|
|
The diversity and bizarre beauty of the Rotifera, a little known group of predominantly freshwater animals, is revealed by high resolution digital images in greater detail than ever before. This illustrated catalog extends the expertise of Frank J. Myers, the foremost rotiferologist of his generation, by taking advantage of the technological advances of today’s generation. More than 700 species are included, providing complete coverage of the world’s most comprehensive rotifer collection on microslides. Includes an introduction to Frank J. Myers by Howard L. Taylor.

Mineralogy of Pennsylvania 1922-1965: Supplementing and Updating Gordon’s “The Mineralogy of Pennsylvania (1922)”: Special Pub. No. 9 of The Acad. of Natural Sciences of Phila.
|
|
|
In 1922 Samuel Gordon’s “The Mineralogy of PA” was pub. by the Acad. of Natural Sci. The editing of the material incorp. in this updated vol. utilizes and brings up-to-date the more significant data bearing on mineral discoveries, occurrences and origin, and covers the period of pub. of a one-page column, “PA Minerals,” in the Keystone Newsletter, monthly journal of the Mineralogical Soc. of PA from 1962-1965. Contents: (1) Aims, and Contents; (2) Revised List of PA Minerals; (3) Descriptive Mineralogy of Newly Recorded Species; (4) New Data on Earlier Recorded Minerals: Minerals of Historical Interest; Minerals of Geochem. Interest; and Zeolites and Related Secondary Minerals; and (5) Index of PA Minerals and Mineral Localities. Illustrations.

Changing Scenes in the Natural Sciences, 1776-1976: A Symposium to Commemorate the Bicent. of the U.S.: Special Pub. of The Academy of Natural Sciences of Phila., No. 12
|
|
|
This book is the result of a symposium held in Phila., PA, in April 1976, on the bicentennial of Amer. independence. It reviewed the contributions of evolution, systematics, quantitative genetics, ecology, and sociobiology to our understanding of the natural world. The papers identify fundamental shortcomings existing within each discipline. They suggest a need for an integration of these sciences and a more thorough testing within each discipline of the theory of evolution by means of natural selection. Papers are organized by theme: The Changing Scenes; The Influence of the New World on the Study of Natural History; Evolution and Systematics; Population Genetics; Terrestrial Ecology; Aquatic Ecology; and Behavior and Sociobiology.

Lewis and Clark Herbarium: Academy of Natural Sciences of Philadelphia Digital Imagery Study Set: Special Publication 19
|
|
|
The Lewis and Clark (L&C) Expedition of 1804-1806 is one of the great stories of exploration in America. Few of the scientific specimens collected by L&C survive, except for hundreds of pressed plants in The Acad. of Natural Sciences in Phila. Digital images in this CD-ROM show each plant in more detail than ever before. Browse through the collection, plant by plant. Read the labels written by Lewis in the field. Refer to facsimile reprints of the original records and colored engravings of Lewis’s gatherings as pub. in the first comprehensive catalogue of American plants by Frederick Pursh in 1813. Read facsimile reprints of important 19th cent. pub. about the plants. Scientific descriptions and comments by L&C scholars bring the herbarium up-to-date.

Annotated Bibliography of Quaternary Shorelines: Second Supplement 1970-1973: Special Publication 11 of the Academy of Natural Sciences of Philadelphia
|
|
|
This work is the Second Supplement to the Annotated Bibliography of Quaternary Shorelines pub. by the Academy of Natural Sciences in 1965 (Special Pub. 6), which covered the years 1945 through 1964 & contained about 2400 abstracts. The First Supplement, pub. by the Academy in 1970, covered the years 1965 through 1969 (Special Pub. 10) & contained slightly more than 1800 abstracts. This supplement covers the years 1970 through 1973 & contains about 2100 abstracts. A few pre-1970 abstracts are included, mainly of articles pub. in 1969 which reached the Academy too late for pub. in the 1970 vol. There are also some earlier abstracts, mainly from areas not thoroughly covered in the previous volumes.

Bone Sharp: The Life of Edward Drinker Cope: Special Publications of The Acad. of Natural Sciences of Phila., No. 17
|
|
|
Edward Drinker Cope (1840-1897), the grandson of wealthy Phila. merchant, grew up to be a keenly intellectual, energetic, and argumentative naturalist. He was among the last of the great school of late 19th century naturalists who studied almost everything, excelling in the study of reptiles, amphibians, and fish, fossil and modern alike. Cope soared to international prominence among natural scientists. Here, Davidson has critically looked into Cope the man more than any other previous biographer. Cope was acclaimed by international scholarly soc. for his scientific work, yet lost his fortune in bad mining ventures & remained a complex, fierce-minded man. Davidson shows him to have been a very human, personable, self-assured, and brilliant man. Illus.

Diatoms of Low-Alkalinity Lakes in the Northeastern United States: Academy of Natural Sciences of Phila., Special Pub 18
|
|
|
Diatoms are valuable ecological indicators. In lakes, diatoms accrue in sediments over time, providing a lasting record of response to changing environ. conditions. Data from analysis of this record can be used to address many environ. issues, incl. lake acidification, eutrophication and climate change. Successful use of diatoms to assess ecological conditions requires that taxa be identified correctly and that their ecological characteristics be known. This publication contains photomicrographs and ecological data for diatom taxa found in sediment samples collected from 116 lakes in the Adirondack Park, N.Y. The taxonomic and ecological info. is applicable to low-alkalinity lakes throughout the NE U.S. and SE Canada. 37 plates.

Annotated Bibliography of Quaternary Shorelines (1945-1964): Special Pub. 6 of the Academy of Natural Sciences of Philadelphia
|
|
|
This bibliography was first suggested at a meeting of the Commission on Shorelines at the sixth congress of the International Assoc. for Quaternary Reserarch (INQUA) held in Warsaw, Poland, in Sept. 1961. Funds for its preparation & pub. were provided by the National Science Foundation (NSF: Grant GN 163), & work started during the summer of 1963. The present work lists some 2400 articles. While the bibliography was intended to cover a 20-year period from 1945 to 1964, there are undoubtedly conspicuous gaps for the year 1964 because not all pertinent pubs. were available by the time that the vol. went to press, early in 1965.
