A speleothem record of hydroclimate variability in northwestern Madagascar during the mid-late Holocene
We present a continuous high-resolution precisely dated multiproxy record of hydroclimate variability at Anjohibe cave in northwestern Madagascar using speleothem AB13. The record spans from ~4484 y BP to ~2863 y BP. Stalagmite δ 18 O, δ 13 C and Sr/Ca ratios show very similar changes in hydroclimate. The mechanism controlling Sr/Ca changes, however, from prior calcite precipitation to degree of dolomite dissolution at about 4 ky BP. Our record i…
The Gender of the Neuronovel
For good reasons, most criticism of the term neuronovel has focused on the impact that the eye-catching and fashionable prefix “neuro” has upon the stem, “novel.” For less clear reasons, the canon of neuronovels (primarily bequeathed by Marco Roth) has tended to pivot on a homogeneously white-male axis, dominated by Mark Haddon, Jonathan Lethem, Ian McEwan, and Richard Powers. This essay explores what we might learn by enlarging the scale of our …

Speleothem records of changes in tropical hydrology over the Holocene and possible implications for atmospheric methane
Recent speleothem records from the tropics of both hemispheres document a gradual decrease in the intensity of the monsoons in the Northern Hemisphere and increase in the Southern Hemisphere monsoons over the Holocene. These changes are a direct response of the monsoons to precession-driven insolation variability. With regard to atmospheric methane, this shift should result in a decrease in Northern Hemisphere tropical methane emissions and incre…
Paleoclimatic implications of the spatial patterns of modern and LGM European land-snail shell δ 18 O
The oxygen isotopic composition of land-snail shells may provide insight into the source region and trajectory of precipitation. Last glacial maximum (LGM) gastropod shells were sampled from loess from Belgium to Serbia and modern land-snail shells both record δ 18 O values between 0‰ and − 5‰. There are significant differences in mean fossil shell δ 18 O between sites but not among genera at a single location. Therefore, we group δ 18 O values f…
High resolution stalagmite climate record from the Yucatán Peninsula spanning the Maya terminal classic period
Holocene ITCZ and Indian monsoon dynamics recorded in stalagmites from Oman and Yemen (Socotra)
Regional atmospheric circulation change in the North Pacific during the Holocene inferred from lacustrine carbonate oxygen isotopes, Yukon Territory, Canada
Analyses of sediment cores from Jellybean Lake, a small, evaporation-insensitive groundwater-fed lake, provide a record of changes in North Pacific atmospheric circulation for the last ∽7500 yr at 5- to 30-yr resolution. Isotope hydrology data from the southern Yukon indicate that the oxygen isotope composition of water from Jellybean Lake reflects the composition of mean-annual precipitation, δ 18 O p . Recent changes in the δ 18 O of Jellybean …
Climatic information from δ13C in plants by combining statistical and mechanistic approaches
The approach commonly used to assess the potential for climate reconstruction is to use linear regressions to compare the isotopic signal stored in archives to instrumental climatic data sets. A new method is proposed that combines statistical and mechanistic approaches to extract climatic information from δ 13 C records in organic matter. Both a spatial and a temporal gradient of 13 C discrimination in a moss species commonly found in temperate …
Changing moisture sources over the last 330,000 years in Northern Oman from fluid-inclusion evidence in speleothems
Speleothems from Hoti Cave in northern Oman provide a record of continental pluvial periods over the last 330,000 yr. Periods of rapid speleothem deposition occurred from 6000 to 10,500, 78,000 to 82,000, 120,000 to 135,000, 180,000 to 200,000, and 300,000 to 330,000 yr ago, with little or no growth during the intervening periods. During each of these five pluvial periods, δ D values of water extracted from speleothem fluid inclusions (δ D FI ) a…
Holocene Forcing of the Indian Monsoon Recorded in a Stalagmite from Southern Oman
A high-resolution oxygen-isotope record from a thorium-uranium–dated stalagmite from southern Oman reflects variations in the amount of monsoon precipitation for the periods from 10.3 to 2.7 and 1.4to 0.4thousand years before the present (ky B.P.). Between 10.3 and 8 ky B.P., decadal to centennial variations in monsoon precipitation are in phase with temperature fluctuations recorded in Greenland ice cores, indicating that early Holocene monsoon …
Holocene palaeoclimates of southern Patagonia
Multiproxy palaeoenvironmental and palaeolimnological analyses of two Holocene-age sediment cores from the margin of Lago Cardiel, a 76 m deep, closed-basin lake in southern Patagonia (latitude 49°S), provide information on lake-level changes that can be related to regional palaeoclimate scenarios. Sedimentol ogic (magnetic susceptibility, organic and inorganic carbon content) and environmental indicators (pollen, dia toms, ostracodes and stable …
