Open Thesis Final V2.Pdf
The Pennsylvania State University The Graduate School Department of the Geosciences TAXONOMIC AND ECOLOGIC IMPLICATIONS OF MAMMOTH MOLAR MORPHOLOGY AS MEASURED VIA COMPUTED TOMOGRAPHY A Thesis in Geosciences by Gregory J Smith 2015 Gregory J Smith Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science August 2015 ii The thesis of Gregory J Smith was reviewed and approved* by the following: Russell W. Graham EMS Museum Director and Professor of the Geosciences Thesis Advisor Mark Patzkowsky Professor of the Geosciences Eric Post Director of the Polar Center and Professor of Biology Timothy Ryan Associate Professor of Anthropology and Information Sciences and Technology Michael Arthur Professor of the Geosciences Interim Associate Head for Graduate Programs and Research *Signatures are on file in the Graduate School iii ABSTRACT Two Late Pleistocene species of Mammuthus, M. columbi and M. primigenius, prove difficult to identify on the basis of their third molar (M3) morphology alone due to the effects of dental wear. A newly-erupted, relatively unworn M3 exhibits drastically different characters than that tooth would after a lifetime of wear. On a highly-worn molar, the lophs that comprise the occlusal surface are more broadly spaced and the enamel ridges thicken in comparison to these respective characters on an unworn molar. Since Mammuthus taxonomy depends on the lamellar frequency (# of lophs/decimeter of occlusal surface) and enamel thickness of the third molar, given the effects of wear it becomes apparent that these taxonomic characters are variable throughout the tooth’s life. Therefore, employing static taxonomic identifications that are based on dynamic attributes is a fundamentally flawed practice. -
Newsletter March 2021
Dzanga Sangha Protected Areas © David Santiago Newsletter March 2021 Wildlife During the month of March, the UICN publicly announced two decisions concerning forest elephants. The first one was declaring the forest elephant (Loxodonta Cyclotis) an altogether different species, as until recently it was merely considered a subspecies. The second decision was declaring this species critically endangered. Dzanga Sangha remains for the moment one of the few places in all of Africa where the number of individuals has remained relatively stable in recent years, and it is also the place where they are most easily observed. The links attached below talk more about this subject. https://www.theguardian.com/environment/2021/mar/25/shades-of-grey-how-to-tell-african-elephant-species-apart- aoe https://www.theguardian.com/commentisfree/2021/mar/25/africas-forest-elephant-has-been-largely-overlooked-now- we-need-to-fight-for-it-aoe https://www.nationalgeographic.com/animals/article/both-african-elephant-species-are-now-endangered-one-critically https://citizen.co.za/news/south-africa/environment/2466472/african-elephant-status-change-a-wake-up-call-for- humans/ https://theconversation.com/new-decisions-by-global-conservation-group-bolster-efforts-to-save-africas-elephants- 158157 In the other hand, Terence Fuh, Head of Primate Habituation, Research and Monitoring for the DSPA has been listed among the top 100 Young African Conservation Leaders, out of the 565 nominations received from 425 youth organizations and networks which underwent a rigorous judging and verification process. https://top100youth.africa/ Over the last three years we have had a total of 4 gorillas babies born into the three habituated groups in DSPA. -
A Report on Late Quaternary Vertebrate Fossil Assemblages from the Eastern San Francisco Bay Region, California
PaleoBios 30(2):50–71, October 19, 2011 © 2011 University of California Museum of Paleontology A report on late Quaternary vertebrate fossil assemblages from the eastern San Francisco Bay region, California SUSUMU TOMIYA*,1,2,3, JENNY L.

At least six species of extinct mammalian megaherbivores are known from Pacheco 1. The probable occurrence of Megalonyx jeffersonii suggests a late Pleistocene age for the assemblage. Pacheco 2 has yielded a minimum of 20 species of mammals, and provides the first unambiguous Quaternary fossil record ofUrocyon , Procyon, Antrozous, Eptesicus, Lasiurus, Sorex ornatus, Tamias, and Microtus longicaudus from the San Francisco Bay region. While a radiocarbon date of 405 ± 45 RCYBP has been obtained for a single bone sample from Pacheco 2, the possibility that much of the assemblage is considerably older than this date is suggested by (1) the substantial loss of collagen in all other samples for which radiocarbon dating was unsuccessfully attempted and (2) the occurrence of Microtus longicaudus approximately 160 km to the west of, and 600 m lower in elevation than, its present range limit. -
Distinguishing Extant Elephants Ivory from Mammoth Ivory Using a Short
www.nature.com/scientificreports OPEN Distinguishing extant elephants ivory from mammoth ivory using a short sequence of cytochrome b gene Jacob Njaramba Ngatia1, Tian Ming Lan2,3,4, Yue Ma1,5, Thi Dao Dinh1, Zhen Wang1,5, Thomas D. Dahmer6 & Yan Chun Xu1,5,7* Trade in ivory from extant elephant species namely Asian elephant (Elephas maximus), African savanna elephant (Loxodonta africana) and African forest elephant (Loxodonta cyclotis) is regulated internationally, while the trade in ivory from extinct species of Elephantidae, including woolly mammoth, is unregulated. This distinction creates opportunity for laundering and trading elephant ivory as mammoth ivory. The existing morphological and molecular genetics methods do not reliably distinguish the source of ivory items that lack clear identifcation characteristics or for which the quality of extracted DNA cannot support amplifcation of large gene fragments. We present a PCR-sequencing method based on 116 bp target sequence of the cytochrome b gene to specifcally amplify elephantid DNA while simultaneously excluding non-elephantid species and ivory substitutes, and while avoiding contamination by human DNA. The partial Cytochrome b gene sequence enabled accurate association of ivory samples with their species of origin for all three extant elephants and from mammoth. The detection limit of the PCR system was as low as 10 copy numbers of target DNA. The amplifcation and sequencing success reached 96.7% for woolly mammoth ivory and 100% for African savanna elephant and African forest elephant ivory. This is the frst validated method for distinguishing elephant from mammoth ivory and it provides forensic support for investigation of ivory laundering cases. -
Behavioral Characteristics of Sri Lankan Elephants
Asian Elephants in Culture & Nature Behavioral Characteristics of Sri Lankan Elephants Jinadasa Katupotha1, Aravinda Ravibhanu Sumanarathna2 ABSTRACT Two species of elephants are traditionally recognized, the African elephant (Loxodontaafricana) and the Asian elephant (Elephas maximus). The Asian Elephant (also recognized as the Indian Elephant) is a large land animal (smaller than the African Elephant) that lives in India, Malaysia, Sumatra, and Sri Lanka. This elephant is used extensively for labor; very few are left in the wild. Their life span is about 70 years. Classification of animals shows that the Sri Lankan elephants belong to Kingdom Animalia (animals), Phylum Chordata, Class Mammallia (mammals), Order Proboscidea, Family Elephantidae, Genus Elephas, Species E. maximus. Herds of elephants live in tight matriarchal family groups consisting of related females. A herd is led by the oldest and often largest female in the herd, called a matriarch. A herd would consist of 6-100 individuals depending on territory, environment suitability and family size. Compared to other mammals, elephants show signs of grief, joy, anger and have fun. They are extremely intelligent animals and have memories that would span many years. It is this memory that serves matriarchs well during dry seasons when they need to guide their herds, sometimes for tens of miles to watering holes that they remember from the past. Mating Season of the elephants is mostly during the rainy season and the gestation period is 22 months. At birth a calf (twins rare) weighs between 90 - 110 kg. As a calf's trunk at birth has no muscle quality it suckles with its mouth. -
The Easternmost Occurrence of Mammut Pacificus (Proboscidea: Mammutidae), Based on a Partial Skull from Eastern Montana, USA

Dooley Jr1 and Charlotte J.H. Hohman2,3 1 Western Science Center, Hemet, CA, United States of America 2 Museum of the Rockies, Montana State University, Bozeman, MT, United States of America 3 Department of Earth Sciences, Montana State University, Bozeman, MT, United States of America ABSTRACT Mammut pacificus is a recently described species of mastodon from the Pleistocene of California and Idaho. We report the easternmost occurrence of this taxon based upon the palate with right and left M3 of an adult male from the Irvingtonian of eastern Montana. The undamaged right M3 exhibits the extreme narrowness that characterizes M. pacificus rather than M. americanum. The Montana specimen dates to an interglacial interval between pre-Illinoian and Illinoian glaciation, perhaps indicating that M. pacificus was extirpated in the region due to habitat shifts associated with glacial encroachment.

México - [email protected], [email protected], [email protected] 2Facultad de Ciencias de la Tierra, Universidad Autónoma de Nuevo León, Linares, México - [email protected] SUMMARY: Aim of this study is to clarify the occurrence of the American mastodon Mammut americanum at the southern portion of its distribution. Twenty-three specimens from 15 localities in Mexico have been recorded, most of them from the Central Plateau, up to an altitude of 1500 meters above sea level, and to the east of the country. In addition, the mammoth Mammuthus and the American mastodon are contemporaneous in three localities, and mastodon possible association with man in two localities. Their southernmost record is from Honduras. Our data indicate that the American mastodon is a rare taxon at the southern portion of its distribution, which could be related to the presence and possible feeding overlap with the gomphothere Cuvieronius. 1.

La Brea and Beyond: the Paleontology of Asphalt-Preserved Biotas
La Brea and Beyond: The Paleontology of Asphalt-Preserved Biotas Edited by John M. Harris Natural History Museum of Los Angeles County Science Series 42 September 15, 2015 Cover Illustration: Pit 91 in 1915 An asphaltic bone mass in Pit 91 was discovered and exposed by the Los Angeles County Museum of History, Science and Art in the summer of 1915. The Los Angeles County Museum of Natural History resumed excavation at this site in 1969. Retrieval of the “microfossils” from the asphaltic matrix has yielded a wealth of insect, mollusk, and plant remains, more than doubling the number of species recovered by earlier excavations. Today, the current excavation site is 900 square feet in extent, yielding fossils that range in age from about 15,000 to about 42,000 radiocarbon years.

The remains were recovered mostly from ca. 170–260 cm below the current land surface in marl overlain by peat and peaty marl. The stratigraphy of the site indicates that the remains were deposited in a small, open-water pond that subsequently filled. The skeleton, which is 41–48% complete, is that of a mature female, ca. -

We have attempted to interpret the biogeographical history of trilophodont gomphotheres in the context of the geological evolution of the continents they inhabited during the Cenozoic. To reconstruct this biogeographic history we used DIVA 1.1. This application resulted in an exact solution requiring three vicariant events, and 15 dispersal events, most of them (i.e., 14) occurring at terminal taxa. The single dispersal event at an internal node affected the common ancestor to Sinomastodon plus the clade Cuvieronius – Stegomastodon. A vicariant event took place which resulted in two isolated groups: (1) Amebelodontinae (Africa – Europe – Asia) and (2) Gomphotheriinae (North America). The Amebelodontinae clade was split by a second vicariant event into Archaeobelodon (Africa and Europe), and the ancestors of the remaining genera of the clade (Asia). In contrast, the Gomphotheriinae clade evolved mainly in North America. -
Thailand About Wildaid
THAILAND ABOUT WILDAID ildAid’s mission is to end the illegal wildlife trade in our lifetimes by reducing demand Wthrough public awareness campaigns and providing comprehensive marine protection. The illegal wildlife trade is estimated to be worth over $10 billion (USD) per year and has drastically reduced many wildlife populations around the world. Just like the drug trade, law and enforcement efforts have not been able to resolve the problem. Every year, hundreds of millions of dollars are spent protecting animals in the wild, yet virtually nothing is spent on stemming the demand for wildlife parts and products. WildAid is the only organization with a mission focused on reducing the demand for these products, with the strong and simple message: When the buying stops, the killing can too. Via public service announcements and short-form documentary pieces, WildAid partners with Save the Elephants and African Wildlife Foundation to educate consumers and to reduce the demand for ivory products worldwide. Through our highly leveraged pro-bono media distribution EVERY YEAR, UP TO outlets, our message reaches hundreds of millions of people each year in China alone. www.wildaid.org CONTACT INFORMATION WILDAID 333 Pine Street #300 San Francisco, CA 94104 33,000 ELEPHANTS Tel: 415.834.3174 Christina Vallianos ARE KILLED FOR THEIR IVORY [email protected] PARTNERS Special thanks Save the Elephants to the following supporters & partners African Wildlife Foundation who have made this work possible: PHOTOGRAPHERS Poulomee Basu Kristian Schmidt Vichan Poti Chris Schmid COVER PHOTO Chris Schmid IVORY DEMAND IN THAILAND | wildaid.org/elephants PAGE // 2 PAGE // 3 Baby elephant staying next to its mother in Etosha National Park, Namibia (Chris Schmid) EXECUTIVE SUMMARY rowing affluence in Asia has and control ivory trading and aware that Thailand’s ivory Gproduced a new class of ivory possession by passing the new trade is contributing to the consumers who have reignited Elephant Ivory Act in 2015 and poaching crisis in Africa.
