The Giant Sea Mammal That Went Extinct in Less Than Three Decades
The Giant Sea Mammal That Went Extinct in Less Than Three Decades The quick disappearance of the 30-foot animal helped to usher in the modern science of human-caused extinctions. JACOB MIKANOWSKI, THE ATLANTIC 4/19/17 HTTPS://WWW.THEATLANTIC.COM/SCIENCE/ARCHIVE/2017/04/PLEIST OSEACOW/522831/ The Pleistocene, the geologic era immediately preceding our own, was an age of giants. North America was home to mastodons and saber-tooth cats; mammoths and wooly rhinos roamed Eurasia; giant lizards and bear-sized wombats strode across the Australian outback. Most of these giants died at the by the end of the last Ice Age, some 14,000 years ago. Whether this wave of extinctions was caused by climate change, overhunting by humans, or some combination of both remains a subject of intense debate among scientists. Complicating the picture, though, is the fact that a few Pleistocene giants survived the Quaternary extinction event and nearly made it intact to the present. Most of these survivor species found refuge on islands. Giant sloths were still living on Cuba 6,000 years ago, long after their relatives on the mainland had died out. The last wooly mammoths died out just 4,000 years ago. They lived in a small herd on Wrangel Island north of the Bering Strait between the Chukchi and East Siberian Seas. Two-thousand years ago, gorilla-sized lemurs were still living on Madagascar. A thousand years ago, 12-foot-tall moa birds were still foraging in the forests of New Zealand. Unlike the other long-lived megafauna, Steller’s sea cows, one of the last of the Pleistocene survivors to die out, found their refuge in a remote scrape of the ocean instead of on land. -
A Middle Holocene Steppe Bison and Paleoenvironments from the Versleuce Meadows, Whitehorse, Yukon, Canada Grant D
1138 ARTICLE A middle Holocene steppe bison and paleoenvironments from the Versleuce Meadows, Whitehorse, Yukon, Canada Grant D. Zazula, Elizabeth Hall, P. Gregory Hare, Christian Thomas, Rolf Mathewes, Catherine La Farge, André L. Martel, Peter D. Heintzman, and Beth Shapiro Abstract: A partial skeleton of a bison was recovered during residential house construction in Whitehorse, Yukon, Canada. The specimen represents a young (estimated 6 year old) bison individual that died, was partially scavenged by carnivores, and subsequently buried by calcareous silt sediment in a pond or small lake during the middle Holocene, ϳ5400 years ago. Palaeoenvironmental data, including molluscs, pollen, vascular plant, and bryophyte macrofossils demonstrate that the small waterbody was surrounded by white spruce dominated boreal forest. Morphometric analysis of the skeleton reveals that its taxonomic affinity is ambiguous, likely owing to it representing an ontogenetically young individual, though it does share some cranial and horn core characteristics of named species such as Bison occidentalis or Bison priscus. Mitochondrial genomic data confirm that this bison belongs to Clade 2A (northern clade), which represents Pleistocene steppe bison (B. cf. priscus) in Beringia through the Holocene and is not represented in living bison species. These data further demonstrate that northern steppe bison population survived the late Pleistocene extinction event, persisted locally in southern Yukon into the Holocene, and are best characterized as a species with a high degree of morphological variability and ecological flexibility.

Overkill, Glacial History, and the Extinction of North America's Ice Age Megafauna
PERSPECTIVE Overkill, glacial history, and the extinction of North America’s Ice Age megafauna PERSPECTIVE David J. Meltzera,1 Edited by Richard G. Klein, Stanford University, Stanford, CA, and approved September 23, 2020 (received for review July 21, 2020) The end of the Pleistocene in North America saw the extinction of 38 genera of mostly large mammals. As their disappearance seemingly coincided with the arrival of people in the Americas, their extinction is often attributed to human overkill, notwithstanding a dearth of archaeological evidence of human predation. Moreover, this period saw the extinction of other species, along with significant changes in many surviving taxa, suggesting a broader cause, notably, the ecological upheaval that occurred as Earth shifted from a glacial to an interglacial climate. But, overkill advocates ask, if extinctions were due to climate changes, why did these large mammals survive previous glacial−interglacial transitions, only to vanish at the one when human hunters were present? This question rests on two assumptions: that pre- vious glacial−interglacial transitions were similar to the end of the Pleistocene, and that the large mammal genera survived unchanged over multiple such cycles. Neither is demonstrably correct. Resolving the cause of large mammal extinctions requires greater knowledge of individual species’ histories and their adaptive tolerances, a fuller understanding of how past climatic and ecological changes impacted those animals and their biotic communities, and what changes occurred at the Pleistocene−Holocene boundary that might have led to those genera going extinct at that time. Then we will be able to ascertain whether the sole ecologically significant difference between previous glacial−interglacial transitions and the very last one was a human presence. -
Incorporating a Deeper Temporal Perspective Into Modern Ecology Felisa A

Boyer2 1Department of Biology, University of New Mexico, Albuquerque, NM 87131, USA. [email protected]; http://biology.unm.edu/fasmith/ 2Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville, TN 37996, USA. [email protected]; http://eeb.bio.utk.edu/boyer/index.html Abstract. Ecologists readily acknowledge that a temporal perspective is essential for untangling ecological complexity, yet most studies remain of relatively short duration. Despite a number of excellent essays on the topic, only recently have ecologists begun to explicitly incorporate a historical component. Here we provide several concrete examples drawn largely from our own work that clearly illustrate how the adoption of a longer temporal perspective produces results significantly at odds with those obtained when relying solely on modern data. We focus on projects in the areas of conservation, global change and macroecology because such work often relies on broad-scale or synthetic data that may be heavily influenced by historic or prehistoric anthropogenic factors. Our analysis suggests that considerable care should be taken when extrapolating from studies of extant systems. Few, if any, modern systems have been unaffected by anthropogenic influences. We encourage the further integration between paleoecologists and ecologists, who have been historically segregated into different departments, scientific societies and scientific cultures.

Leo Linnartz (Ark Nature) Summary of: Aurochs Genetics, a cornerstone of biodiversity Preface In 2015 a report is written on Aurochs genetics, made possible by a grant from the Dutch Liberty Wildlife fund. This fund provided the Taurus foundation with a grant of EUR 20.000 to conduct genetic research on aurochs and its relation with nowadays so- called ‘primitive’ breeds. This is the summary of that report. This summary shortly describes the current state of affairs, what we do know early 2015 about the aurochs, about domestic cattle and the relationship of aurochs and the primitive breeds used in the Tauros Programme.
