A Critique of Phanerozoic Climatic Models Involving Changes in The
Earth-Science Reviews 56Ž. 2001 1–159 www.elsevier.comrlocaterearscirev A critique of Phanerozoic climatic models involving changes in the CO2 content of the atmosphere A.J. Boucot a,), Jane Gray b,1 a Department of Zoology, Oregon State UniÕersity, CorÕallis, OR 97331, USA b Department of Biology, UniÕersity of Oregon, Eugene, OR 97403, USA Received 28 April 1998; accepted 19 April 2001 Abstract Critical consideration of varied Phanerozoic climatic models, and comparison of them against Phanerozoic global climatic gradients revealed by a compilation of Cambrian through Miocene climatically sensitive sedimentsŽ evaporites, coals, tillites, lateritic soils, bauxites, calcretes, etc.. suggests that the previously postulated climatic models do not satisfactorily account for the geological information. Nor do many climatic conclusions based on botanical data stand up very well when examined critically. Although this account does not deal directly with global biogeographic information, another powerful source of climatic information, we have tried to incorporate such data into our thinking wherever possible, particularly in the earlier Paleozoic. In view of the excellent correlation between CO2 present in Antarctic ice cores, going back some hundreds of thousands of years, and global climatic gradient, one wonders whether or not the commonly postulated Phanerozoic connection between atmospheric CO2 and global climatic gradient is more coincidence than cause and effect. Many models have been proposed that attempt to determine atmospheric composition and global temperature through geological time, particularly for the Phanerozoic or significant portions of it. Many models assume a positive correlation between atmospheric CO2 and surface temperature, thus viewing changes in atmospheric CO2 as playing the critical role in r regulating climate temperature, but none agree on the levels of atmospheric CO2 through time. -
Conservation Strategy for Allotropa Virgata (Candystick), U.S
CONSERVATION STRATEGY FOR ALLOTROPA VIRGATA (CANDYSTICK), U.S. FOREST SERVICE, NORTHERN AND INTERMOUNTAIN REGIONS by Juanita Lichthardt Conservation Data Center Natural Resource Policy Bureau October, 1995 Idaho Department of Fish and Game 600 South Walnut, P.O. Box 25 Boise, Idaho 83707 Jerry M. Conley, Director Cooperative Challenge Cost-share Project Nez Perce National Forest Idaho Department of Fish and Game Purchase Order No.:95-17-20-001 ACKNOWLEDGMENTS I am grateful to the following Forest Service sensitive plant coordinators and botanists who went out of their way to provide valuable consultation, maps, and data: Leonard Lake, Linda Pietarinen, Jim Anderson, Quinn Carver, Alexia Cochrane, and John Joy. These same people are largely responsible for our current level of knowledge about Allotropa virgata. Special thanks to Janet Johnson and Marilyn Olson who found the time to show me Allotropa sites on the Bitterroot and Payette National Forests, respectively. Steve Shelly, Montana Natural Heritage Program/US Forest Service, initiated this project and provided thoughtful review. I hope that this document provides both the practical guidance and theoretical basis needed for a coordinated effort by management agencies toward conservation of Allotropa virgata. i ABSTRACT This conservation strategy provides recommendations for management of National Forest lands supporting and adjoining populations of Allotropa virgata (candystick), a plant species designated as sensitive in Regions 1 and 4 of the US Forest Service. Allotropa virgata presents a special conservation challenge because it is part of a three-way symbiosis involving conifers and their ectomycorrhizal fungi. First, the current state of our knowledge of the species is summarized, including distribution, habitat, ecology, population biology, monitoring results, past impacts, and perceived threats. -

NUTRIENT RESOURCES AND STOICHIOMETRY AFFECT THE ECOLOGY OF ABOVE- AND BELOWGROUND INVERTEBRATE CONSUMERS by JAYNE LOUISE JONAS B.S., Wayne State College, 1998 M.S., Kansas State University, 2000 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree DOCTOR OF PHILOSOPHY Division of Biology College of Arts and Sciences KANSAS STATE UNIVERSITY Manhattan, Kansas 2007 Abstract Aboveground and belowground food webs are linked by plants, but their reciprocal influences are seldom studied. Because phosphorus (P) is the primary nutrient associated with arbuscular mycorrhizal (AM) symbiosis, and evidence suggests it may be more limiting than nitrogen (N) for some insect herbivores, assessing carbon (C):N:P stoichiometry will enhance my ability to discern trophic interactions. The objective of this research was to investigate functional linkages between aboveground and belowground invertebrate populations and communities and to identify potential mechanisms regulating these interactions using a C:N:P stoichiometric framework. Specifically, I examine (1) long-term grasshopper community responses to three large-scale drivers of grassland ecosystem dynamics, (2) food selection by the mixed-feeding grasshopper Melanoplus bivittatus, (3) the mechanisms for nutrient regulation by M. bivittatus, (4) food selection by fungivorous Collembola, and (5) the effects of C:N:P on invertebrate community composition and aboveground-belowground food web linkages. In my analysis of grasshopper community responses to fire, bison grazing, and weather over 25 years, I found that all three drivers affected grasshopper community dynamics, most likely acting indirectly through effects on plant community structure, composition and nutritional quality. In a field study, the diet of M. -
Ectomycorrhizal Fungal Assemblages of Nursery-Grown Scots Pine Are Influenced by Age of the Seedlings
Article Ectomycorrhizal Fungal Assemblages of Nursery-Grown Scots Pine are Influenced by Age of the Seedlings Maria Rudawska * and Tomasz Leski Institute of Dendrology, Polish Academy of Sciences, Parkowa 5, 62-035 Kórnik, Poland; [email protected] * Correspondence: [email protected] Abstract: Scots pine (Pinus sylvestris L.) is the most widely distributed pine species in Europe and is relevant in terms of planted areas and harvest yields. Therefore, each year the demand for planting stock of Scots pine is exceedingly high, and large quantities of seedlings are produced annually throughout Europe to carry out reforestation and afforestation programs. Abundant and diverse ectomycorrhizal (ECM) symbiosis is critical for the success of seedlings once planted in the field. To improve our knowledge of ECM fungi that inhabit bare-root nursery stock of Scots pine and understand factors that influence their diversity, we studied the assemblages of ECM fungi present across 23 bare-root forest nurseries in Poland. Nursery stock samples were characterized by a high level of ECM colonization (nearly 100%), and a total of 29 ECM fungal taxa were found on 1- and 2- year-old seedlings. The diversity of the ECM community depended substantially on the nursery and age of the seedlings, and species richness varied from 3–10 taxa on 1-year-old seedlings and 6–13 taxa on 2-year-old seedlings. The ECM fungal communities that developed on the studied nursery stock were characterized by the prevalence of Ascomycota over Basidiomycota members on 1-year-old seedlings. All ecological indices (diversity, dominance, and evenness) were significantly affected by age of the seedlings, most likely because dominant ECM morphotypes on 1-year-old seedlings (Wilcoxina mikolae) were replaced by other dominant ones (e.g., Suillus luteus, Rhizopogon roseolus, Thelephora terrestris, Hebeloma crustuliniforme), mostly from Basidiomycota, on 2-year-old seedlings. -

No part of this publication may be reproduced, stored in a retrieval system or database, or transmitted in any form or by any means, including photocopying, without written permission of the authors. Produced with financial assistance from The Couchiching Conservancy. The City of Kawartha Lakes Flora Project is sponsored by the Kawartha Field Naturalists based in Fenelon Falls, Ontario. In 2008, information about plants in CKL was scattered and scarce. At the urging of Michael Oldham, Biologist at the Natural Heritage Information Centre at the Ontario Ministry of Natural Resources and Forestry, Dale Leadbeater and Anne Barbour formed a committee with goals to: • Generate a list of species found in CKL and their distribution, vouchered by specimens to be housed at the Royal Ontario Museum in Toronto, making them available for future study by the scientific community; • Improve understanding of natural heritage systems in the CKL; • Provide insight into changes in the local plant communities as a result of pressures from introduced species, climate change and population growth; and, • Publish the findings of the project . Over eight years, more than 200 volunteers and landowners collected almost 2000 voucher specimens, with the permission of landowners. Over 10,000 observations and literature records have been databased. The project has documented 150 new species of which 60 are introduced, 90 are native and one species that had never been reported in Ontario to date. -
