The Exhibition: Focus on Nature is a biennial exhibition of scientific, natural and cultural history. It began in 1990 in conjunction with the Northeast Natural History Conference. While the opening still coincides with the conference, the exhibit has taken on a life of its own and each year the geographical representation, breadth of subject matter and quality has increased to a level of high standard and international participation. The central purpose of Focus on Nature is to highlight illustration as a way of communicating observations of scientists and artists. Scientific discovery and illustration have always been linked, and they have advanced together. At the New York State Museum, there is a research tradition that extends back to the founding of the State Geologi- cal and Natural History Survey of 1836. Illustrations have constantly been a part of the effort to communicate the results of these studies. Purchase Awards have been offered for the past five exhibits to enhance the educational value of the NYS Museum’s Illustration Collection. The purchase(s) are selected on the basis of high technical quality, scientific ac- curacy, aesthetic achievement, and educational value. The artwork becomes part of the permanent collection owned by the people of New York State. Focus on Nature X will be exhibited from April 17–September 7, 2008. Keynote Address Dr. Kenneth B. Storey Professor of Biochemistry, Institute of Biochemistry and Departments of Biology and Chemistry, Carleton University Thursday, April 17, 2008 8:00 p.m. – 9:30 p.m. Clark Auditorium, New York State Museum Life in the Cold: A Biochemist’s Perspective on Animals in Winter Storey*, Kenneth B. (Institute of Biochemistry, Carleton University, Ottawa, Ontario, Canada) Winter temperatures below 0 °C pose a severe challenge to animal life. For many species, food supplies fail, the risk of freezing is high, endotherms are plagued by massive energy costs to stay warm, and ectotherms have low metabolic rates that are not conducive to growth and development. Some organisms escape winter by migration or avoid severe cold exposure by retreating under water or deep under ground but many must employ biochemical strategies to preserve life. My lab explores the metabolic and gene adaptations that support two main strategies of animal cold survival: mammalian hibernation and ectotherm freeze tolerance. Our hibernation studies analyze the regulatory mechanisms that allow ground squirrels and bats to sink into cold torpor, coordinating and reprioritizing all cell functions so that metabolic rate drops by >95%, body temperature falls to near 0 °C, and tissue viability is preserved over many weeks. Our research on frogs and insects explores life in a frozen state—how organisms deal with the consequences when 65–70% of total body water freezes. Survival requires extensive metabolic adjustments to deal with issues including oxygen deprivation when blood freezes, extreme cell shrinkage caused by water loss to extracellular ice masses, and physical damage to tissues by ice crystals. Hibernation and freeze tolerance are not only fascinating natural phenomena that are critical to the survival of hundreds of species in temperate and polar environments but the mechanisms identified from our studies have key applications in medicine for the long term preservation of human tissues and organs for transplant.

ROBINSON,1,4 LIDA PIGOTT BURNEY,2 AND DAVID A. BURNEY3 1Department of Natural Sciences, Fordham College at Lincoln Center, 113 West 60th Street, New York, New York 10023 USA 2The Louis Calder Biological Station, Fordham University, P.O. Box K, Armonk, New York 10504 USA 3Department of Biological Sciences, Fordham University, 441 East Fordham Road, Bronx, New York 10458 USA Abstract. Stratigraphic palynological analyses of four late Quaternary deposits com- prise a landscape-level study of the patterns and processes of megafaunal extinction in southeastern New York State. Distinctive spores of the dung fungus Sporormiella are used as a proxy for megafaunal biomass, and charcoal particle analysis as a proxy for ®re history. A decline in spore values at all sites is closely followed by a stratigraphic charcoal rise. It is inferred that the regional collapse of a megaherbivory regime was followed by landscape transformation by humans. Correlation with the pollen stratigraphy indicates these devel- opments began many centuries in advance of the Younger Dryas climatic reversal at the end of the Pleistocene. However, throughout the region, the latest bone collagen dates for Mammut are considerably later, suggesting that megaherbivores lasted until the beginning of the Younger Dryas, well after initial population collapse. This evidence is consistent with the interpretation that rapid overkill on the part of humans initiated the extinction process. Landscape transformation and climate change then may have contributed to a cascade of effects that culminated in the demise of all the largest members of North America's mammal fauna.

    Easterla, David A. (Distinguished University Professor of Biology) “A Preliminary Investigation of Pleistocene (Ice Age) Vertebrate/Mammal Fossils Unearthed at Sand/Gravel Pits in Southwest Iowa – (Continued)” Abstract – Northwest Missouri State University Faculty Research Grant Department of Biological A101 25008 222 Sciences 2009-2010 Garrett-Strong Science Building A number of sand/gravel pits in southwest Iowa were investigated for vertebrate 660.562.1388 office fossil remains. These fossils were occasionally unearthed accidently as sand and 660.562.1188 fax gravel were excavated for commercial purposes. Most of the fossils were of local Pleistocene age (still partial bone) and had been mixed with gravel and sand during this period and deposited in curves of the Ice Age rivers. Some of the fossils were completely mineralized and dated back to the Miocene and Pliocene; these fossils undoubtedly were of glacial origin (Kansasan?) and brought South from the North. Most of the mineralized fossils were fragments or badly broken and difficult to identify. Following are Pleistocene fossils identified: Extant: Coyote (Canis latrans), Red Fox (Vulpes fulva), Raccoon (Procyon lotor), Modern Beaver (Castor canadensis), Modern Bison (Bison bison), White- nsand transitions tailed Deer (Odocoileus virginianus), American Elk (Cervus elaphus), and Caribou (Rangifer tarandus). Extinct: Jefferson’s Ground Sloth (Megalonyx jeffersonii), Giant Beaver (Castoroides ohioensis), Ice Age Horses (Equus sp. – three species?), Ice Age Bisons (Bison antiquus and Bison occidentalis), Woodland Muskox (Symbos cavifrons) and Harlan’s Muskox (Bootherium bombifrons) = conspecific?, Fugitive Deer (Sangamona fugitiva)?, Stag-Moose (Cervalces scotti), Columbian Mammoth (Mammuthus columbi), Jefferson’s Mammoth (Mammuthus jeffersonii), Woolly Mammoth (Mammuthus primigenius)?, and American Mastodon (Mammut americanum).

    Florida Field Naturalist 47(3):116-126, 2019. FIELD OBSERVATIONS Winter Report: December 2018-February 2019.—This report consists of significant bird observations compiled by the Field Observations Committee (FOC). Electronic submissions to the FOC should be in the following format: species, number of individuals, age and sex of the bird(s), color morph if applicable, location (including county), date, observer(s), and significance. Seasons are winter (December-February), spring (March-May), summer (June-July), and fall (August-November). Submit observations to regional compilers within two weeks after the close of each season, or to the state compiler within one month. Addresses of the compilers follow this report. Sight-only observations are considered “reports” while only those observations supported by verifiable evidence (photographs, video or audio recordings, or specimens) are called “records.” Species for which documentation is required by the FOC and by the FOS Records Committee (FOSRC; <fosbirds.org/official-florida-state-bird-list>) are marked here with an asterisk (*). A county designation (in italics) accompanies the first- time listing of each site in this report. Abbreviations in this report are: AFB = Air Force Base, AFR = Air Force Range, CA = Conservation Area, EOS = end of season, m. obs. = many observers, NERR = National Estuarine Research Reserve, NF = National Forest, NP = National Park, NSRA = North Shore Restoration Area, NWR = National Wildlife Refuge, SF = State Forest, SP = State Park, STA = Stormwater Treatment Area, STF = sewage treatment facility, WMA=Wildlife Management Area, and N, S, E, W etc., for compass directions. Bold-faced entries denote birds newly reported or verified in Florida, or record numbers.
