Maryland Academy Of Sciences Bulletin

The definitive resource for finding, identifying, and conserving Maryland’s amphibians and reptiles. Naturalists, herpetologists, and ecologists alike agree that tracking herpetofauna is a challenging undertaking. Scientists are concerned about the decline of once-familiar species, but evidence has often been too anecdotal to support firm conclusions. To better understand the distribution of amphibians and reptiles in Maryland and forecast species' futures in a time of accelerated environmental threats, conducting a comprehensive statewide survey updating 1970s-era distribution maps seemed ideal. However, this endeavor was of an impossibly ambitious scope for scientists alone to tackle. Enter the Maryland Amphibian and Reptile Atlas project, comprising nearly a thousand dedicated citizen scientists who discovered and recorded the locations of herpetofauna throughout every corner of Maryland. In The Maryland Amphibian and Reptile Atlas, Heather R. Cunningham and Nathan H. Nazdrowicz present the findings of this massive undertaking. This definitive guide combines nearly 160 comprehensive new herpetological maps with historical distribution maps and in-depth species accounts. Color photos illustrate the natural history of the 89 species of frogs, salamanders, turtles, snakes, and lizards that call the state home. Essays discuss historical studies, the effects of Maryland's current climate, geology, and habitat diversity—and the myriad conservation issues these animals face. This richly detailed book represents a triumph of citizen science and the culmination of an intensive research partnership. It will appeal to both amateurs and professionals interested in herpetology, natural history, or ecology, as well as those with a special interest in Maryland's biodiversity.

A full range of rock art appearances, including dendroglyphs, pictographs, and a selection of portable rock objects The Indians of northeastern North America are known to us primarily through reports and descriptions written by European explorers, clergy, and settlers, and through archaeological evidence. An additional invaluable source of information is the interpretation of rock art images and their relationship to native peoples for recording practical matters or information, as expressions of their legends and spiritual traditions, or as simple doodling or graffiti. The images in this book connect us directly to the Indian peoples of the Northeast, mainly Algonkian tribes inhabiting eastern Pennsylvania, Maryland and the lower Potomac River Valley, New York, New Jersey, the six New EnglandStates, and Atlantic Canada. Lenik provides a full range of rock art appearances in the study area, including some dendroglyphs, pictographs, and a selection of portable rock objects. By providing a full analysis and synthesis of the data, including the types and distribution of the glyphs, and interpretations of their meaning to the native peoples, Lenik reveals a wealth of new information on the culture and lifeways of the Indians of the Northeast.
