Drivers of Beta Diversity in Modern and Ancient Reef-Associated Soft-Bottom Environments
Drivers of beta diversity in modern and ancient reef-associated soft-bottom environments Vanessa Julie Roden1, Martin Zuschin2, Alexander Nützel3,4,5, Imelda M. Hausmann3,4 and Wolfgang Kiessling1 1 GeoZentrum Nordbayern, Section Paleobiology, Friedrich-Alexander University Erlangen-Nürnberg, Erlangen, Germany 2 Department of Palaeontology, University of Vienna, Vienna, Austria 3 SNSB—Bayerische Staatssammlung für Paläontologie und Geologie, Munich, Germany 4 Department of Earth & Environmental Sciences, Ludwig-Maximilians-Universität München, Munich, Germany 5 GeoBio-Center, Ludwig-Maximilians-Universität München, Munich, Germany ABSTRACT Beta diversity, the compositional variation among communities, is often associated with environmental gradients. Other drivers of beta diversity include stochastic processes, priority effects, predation, or competitive exclusion. Temporal turnover may also explain differences in faunal composition between fossil assemblages. To assess the drivers of beta diversity in reef-associated soft-bottom environments, we investigate community patterns in a Middle to Late Triassic reef basin assemblage from the Cassian Formation in the Dolomites, Northern Italy, and compare results with a Recent reef basin assemblage from the Northern Bay of Safaga, Red Sea, Egypt. We evaluate beta diversity with regard to age, water depth, and spatial distance, and compare the results with a null model to evaluate the stochasticity of these differences. Using pairwise proportional dissimilarity, we find very high beta diversity for the Cassian Formation (0.91 ± 0.02) and slightly lower beta diversity for the Bay of Safaga (0.89 ± 0.04). Null models show that stochasticity only plays a minor role in determining faunal differences. Spatial distance is also irrelevant. Contrary to expectations, there is no tendency of beta Submitted 26 September 2019 Accepted 16 April 2020 diversity to decrease with water depth. -

Bush, 1968, pp. 94-99 in: San Juan, San Miguel, La Plata Region (New Mexico and Colorado), Shomaker, J. W.; [ed.], New Mexico Geological Society 19th Annual Fall Field Conference Guidebook, 212 p. This is one of many related papers that were included in the 1968 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Catalogue of Type Fossils in the Geological Museum at the Ohio State University
CATALOGUE OF TYPE FOSSILS IN THE GEOLOGICAL MUSEUM AT THE OHIO STATE UNIVERSITY. HELEN MORNINGSTAR Department of Geology, Ohio State University INTRODUCTION. The following catalogue consists of an alphabetic list of all fossil types (holotypes, paratypes, and cotypes), all subsequently described and figured specimens (plesiotypes), as well as artificial models of type fossils (plastotypes) in the Geological Museum of The Ohio State University. It is patterned directly after the catalogue compiled by Dr. Charles Schuchert, assisted by W. H. Dall, T. W. Stanton, and R. S. Bassler, for the fossil invertebrates in the United States National Museum.1 The catalogue is designed for the convenience of workers in Paleontology and in response to a constant inquiry for informa- tion concerning type specimens of Ohio fossils. Unfortunately, many of the type fossils thought to be located here, according to statements in the older reports of the Geological Survey of Ohio, are missing, and although some of them may have been lost at some former time, it seems probable that many have never been placed in this Museum, but have found their way into other collections. An attempt is now being made to recover as many as possible of the types which have been described in the reports of the Geological Survey of Ohio, and any information concerning tHe location of such specimens will be appreciated. The work of collecting the data for the following catalogue of type fossils extended over a period of several years during which the writer has been engaged in identifying and reclassify- ing the paleontological material in the Geological Museum at The Ohio State University. -

San Juan National Forest
SAN JUAN NATIONAL FOREST Colorado UNITED STATES DEPARTMENT OF AGRICULTURE V 5 FOREST SERVICE t~~/~ Rocky Mountain Region Denver, Colorado Cover Page. — Chimney Rock, San Juan National Forest F406922 UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1942 * DEPOSITED BY T,HE UNITED STATES OF AMERICA San Juan National Forest CAN JUAN NATIONAL FOREST is located in the southwestern part of Colorado, south and west of the Continental Divide, and extends, from the headwaters of the Navajo River westward to the La Plata Moun- \ tains. It is named after the San Juan River, the principal river drainage y in this section of the State, which, with its tributaries in Colorado, drains the entire area within the forest. It contains a gross area of 1,444,953 ^ acres, of which 1,255,977 are Government land under Forest Service administration, and 188,976 are State and privately owned. The forest was created by proclamation of President Theodore Roosevelt on June 3, 1905. RICH IN HISTORY The San Juan country records the march of time from prehistoric man through the days of early explorers and the exploits of modern pioneers, each group of which has left its mark upon the land. The earliest signs of habitation by man were left by the cliff and mound dwellers. Currently with or following this period the inhabitants were the ancestors of the present tribes of Indians, the Navajos and the Utes. After the middle of the eighteenth century the early Spanish explorers and traders made their advent into this section of the new world in increasing numbers. -

Thus, we’ve teamed up with the American Breast Cancer Foundation, an organization that is doing their part to save our world, one breast at a time, in order to do our part, in hopes of becoming role models and encouraging the rest of the world to do their part too. So here’s our plan: We are going to climb Denali (Mount McKinley) via the West Buttress route in June of 2006. -
The Carboniferous Evolution of Nova Scotia
Downloaded from http://sp.lyellcollection.org/ by guest on September 27, 2021 The Carboniferous evolution of Nova Scotia J. H. CALDER Nova Scotia Department of Natural Resources, PO Box 698, Halifax, Nova Scotia, Canada B3J 2T9 Abstract: Nova Scotia during the Carboniferous lay at the heart of palaeoequatorial Euramerica in a broadly intermontane palaeoequatorial setting, the Maritimes-West-European province; to the west rose the orographic barrier imposed by the Appalachian Mountains, and to the south and east the Mauritanide-Hercynide belt. The geological affinity of Nova Scotia to Europe, reflected in elements of the Carboniferous flora and fauna, was mirrored in the evolution of geological thought even before the epochal visits of Sir Charles Lyell. The Maritimes Basin of eastern Canada, born of the Acadian-Caledonian orogeny that witnessed the suture of Iapetus in the Devonian, and shaped thereafter by the inexorable closing of Gondwana and Laurasia, comprises a near complete stratal sequence as great as 12 km thick which spans the Middle Devonian to the Lower Permian. Across the southern Maritimes Basin, in northern Nova Scotia, deep depocentres developed en echelon adjacent to a transform platelet boundary between terranes of Avalon and Gondwanan affinity. The subsequent history of the basins can be summarized as distension and rifting attended by bimodal volcanism waning through the Dinantian, with marked transpression in the Namurian and subsequent persistence of transcurrent movement linking Variscan deformation with Mauritainide-Appalachian convergence and Alleghenian thrusting. This Mid- Carboniferous event is pivotal in the Carboniferous evolution of Nova Scotia. Rapid subsidence adjacent to transcurrent faults in the early Westphalian was succeeded by thermal sag in the later Westphalian and ultimately by basin inversion and unroofing after the early Permian as equatorial Pangaea finally assembled and subsequently rifted again in the Triassic.
