Glacial and vegetation history of the Polar Ural Mountains in northern Russia during the Last Ice Age, Marine Isotope Stages 5–2

Bears Ears National Monument (BENM) is a new, landscape-scale national monument jointly administered by the Bureau of Land Management and the Forest Service in southeastern Utah as part of the National Conservation Lands system. As initially designated, BENM encompasses 1.3 million acres of land with exceptionally fossiliferous rock units. These units comprise a semi-continuous depositional record from the Pennsylvanian Period through the middle of the Cretaceous Period. Additional Quaternary and Holocene deposits are known from unconsolidated river gravels and cave deposits. The fossil record from BENM provides unique insights into several important paleontological periods of time, including the Pennsylvanian-Permian transition from fully aquatic to more fully terrestrial tetrapods; the rise of the dinosaurs following the Triassic-Jurassic extinction; and the response of ecosystems in dry climates to sudden temperature increases at the end of the last ice age and across the Holocene. While the paleontological resources of BENM are extensive, they have historically been under-studied. Here we summarize prior paleontological work in BENM and review the data used to support paleontological resource protection in the 2016 BENM proclamation.

Campbell Island

ABSTRACTCampbell Island is a small, uninhabited peat-covered island lying in the cool southern ocean 600 km south of the New Zealand mainland. Dracophyllum scrub is the main cover from sea level to 200 m, above which tussock grassland, macrophyllous forbs and tundra dominate. Seven peat profiles from sea level to the tundra zone provide an elevational transect for pollen and charcoal records spanning the last 500 years. Scrub density was relatively low between 200 and 400 cal yrs BP, possibly due to Little Ice Age cooling, but had recovered by the time Europeans discovered the island in AD 1810. Burning and grazing during a brief farming episode (AD 1895–1931) severely reduced scrub and palatable grasses and forbs. Vegetation recovery is now well advanced following cessation of farming and the later elimination of all feral grazing animals, cats and rats. Climates were cool in the southwest Pacific during the farming period, and since AD 1970 the island has warmed by c. 0·5°C. However, there has been no upwards movement of the scrubline despite vigorous regeneration of scrub at lower altitudes. The island's cloudy, highly oceanic climate appears to offset increasing summer warmth, and scrubline is likely to rise only if clearer and less windy, as well as warmer, summers eventuate.

The City

The essays in this special issue all focus on the city of Berlin, in particular, its relationship with its margins and borders over thelongue dureé. The authors—Kristin Poling, Marion Gray, Barry Jackisch, and Eli Rubin—all consider the history of Berlin over the last two centuries, with special emphasis on how Berlin expanded over this time and how it encountered the open spaces surrounding it and within it—the “green fields” (grüne Wiesen) referred to in the theme title. Each of them explores a different period in Berlin's history, and so together, the essays form a long dureé history of Berlin, although each of the essays in its own way explores the roots of Berlin's history in deeper time scales, from the early modern period, to the Middle Ages, and even to the very end of the last ice age, more than 10,000 years ago.

Important Evidence

Tierra del Fuego and Patagonia are geographically so closely related that they can he called Fuego-Patagonia. Its two main units are the Andes and the region of the mesetas to the east of them. As a result of the predominantly westerly winds, the rainfall and the forests are concentrated in the Andes whereas in the region of the mesetas and the plains there are steppes and semideserts. The boundary between them seems to be a zone of struggle between the forest and the steppe. Its past oscillations can be studied against the background of palaeogeographic evolution especially since the last ice age. The stratigraphy of bogs and alluvial clays provides most important evidence on this topic. Tierra del Fuego is especially suitable as a study area since bogs are present all over the main island. In order to separate the ice ages with certainty, and thus to find out how many ice ages there were in Fuego-Patagonia, I looked for organic interglacial layers. Those found are the only ones so far recorded in South America. The southernmost is on the east coast of Tierra del Fuego in a till cliff facing the Atlantic Ocean, about 20 km from the Viamonte estancia (figure 26). The peat is, according to a dating at the Yale Geochronometric Laboratory, over 41000 years old. Its macro- and microscopic plant remains reflect a richer flora than the present one.
