En appliquant le concept du diagramme de sécurité à Andhra Pradesh, les AA. espèrent apporter une contribution aux analyses de vulnérabilité dans le domaine des changements climatiques.
A 12,500-yr pollen record from Loon Lake, Wyoming provides information on the climate history of the southwestern margin of Yellowstone National Park. The environmental reconstruction was used to evaluate hypotheses that address spatial variations
Paleoenvironmental changes dating back to 30,000 yr B.P. documented in a pollen record from central Brazil (lat. 19o S) permit the reconstruction of climatic changes related to shifts of the Antarctic polar fronts. The paleoclimatic inferences were
obtained by a study of modern vegetation and pollen distribution, taking into account present-day climatic parameters.

Synthèse de l'histoire de la végétation depuis 15 000 ans dans le Massif Central, à partir de nombreux diagrammes polliniques. Présentation du diagramme de Ribains (Haute-Loire).
The AA. describe 2 detailed pollen records of the late-glacial period from western Oregon. They provide information on late-glacial variations in vegetation and climate and on the extent and character of Younger Dryas cooling in the Pacific
Northwest. They compare them with published data from the the Pacific Northwest and northeast Pacific. A synchronous response at both sites would suggest a regional climatic change. Asynchrony would reflect variations in local climate conditions
of the pollen diagrams reflects a climatic phase with more rain and less-marked seasonality than today. In the middle part, a strong change is recorded in composition and structure of the vegetational landscape, with vegetation appearing that was adapted
Four pollen diagrams from Minorca (Balearic Islands) have been correlated with other previously studied sequences from Majorca and Minorca to define a Holocene landscape sequence for the region from 8000 yr B.P. to the present. The lower part
Grâce à un programme informatique, les données de 167 stations réparties dans le monde entier ont été converties en diagrammes thermo-isoplètes qui sont utiles en bioclimatologie, pour la protection de l'environnement ainsi que pour les voyageurs
Prices of food products in Polish Territory as index of climatic oscillations in the Little Ice Age

oscillations corresponding with climatic changes are found in this diagram. Three periods of a relatively rapid growth of prices can be distinguished which correspond with three cooling waves during Little Ice Age.
The results of studies of three different authors made it possible to plot for Cracow a diagram of prices expressed by a silver equivalent, comprising the period 1369-1914. Besides general tendencies depending on economic conditions, long-term
The AA. present a model to explain the pattern of Holocene vegetational changes in the Rocky Mountains. The model is based on the understanding of : 1) the vegetational and climatic history of the Yellowstone region and the northern Rocky Mountains
of Montana, Wyoming, and Idaho; 2) paleoclimate simulations from general circulation models that incorporate changes in large-scale controls; and 3) present-day climatic regimes of the western United States.
Pollen analysis of sediment cores from Grandfather and Ongivinuk Lakes reveals a record of postglacial vegetation and climate change in the northern Bristol Bay region. The chronology is based on six conventional 14C dates of bulk organic matter
from the Grandfather core. The unique features of these pollen records emphasize the spatial complexity of late Quaternary vegetation and climate history in eastern Beringia.
The purpose of this paper is to document and review further palynological evidence in relation to climatic response (or lack of it) to deglacial drainage changes for the period 10 to 8 ka throughout the Agassiz-Upper Great Lakes region
Basal sediments of Lake Torfadalsvatn record changes in terrestrial and limnic environments in the period 11,300-9000 C-14 yr B.P. These changes were probably forced by climate and connected with displacements of the marine polar front and sea-ice
Pollen evidence from Lake Shayema, Mianning County, was obtained to examine postglacial vegetation and climatic change in southwestern Sichuan. The pollen record displays several changes in the vegetation over the last 11 000 yr. Except
The Banyoles lacustrine sequence shows that the vegetational history of the northeastern Iberian Peninsula during the last 30 000 yr follows the North Atlantic pattern of climatic oscillations. This high-resolution record contains well-preserved

In this paper, the AA. extend the coverage of paleoecologic sites in the Cascade Range by reporting on pollen records from Indian Prairie, in central Oregon. These data disclose the vegetational and climatic history of middle and high elevations

Paleoenvironmental data, including pollen and sediment analyses, radiocarbon ages, and tephra identifications of a core recovered from a fen, provide a ca. 16,500 C 14 yr B.P. record of late Quaternary vegetation and climate change in the Long
Lake Johnston cirque contains some of the best subalpine rainforest in Tasmania. The vegetation composition was studied to determine locally sourced pollen inputs and to interpret the pollen diagram. Magnetic measurements of mineral properties
