Forest change in the northern Yucatan lowlands (Mexico) during Maya cultural periods
Palaeoecological records from the Maya lowlands indicate that there is an emerging pattern of complex vegetation change across the Terminal Classic Period, a time that was characterised by frequent droughts and collapse of major Maya centres. To fully understand the extent of anthropogenic influences on Yucatan forest composition in space and time, more palaeoecological records are needed, as well as a better understanding of the relationship bet…
Past Answers to Present Concerns. The Relevance of the Premodern Past for 21st Century Policy Planners
How is history relevant to the present, or indeed the future? Governments around the world have used history to inform planning and decision‐making in various fields for years, but more recently it has taken on a renewed importance as governments grapple with increasingly complex challenges arising from the impacts of climatic change. Yet identifying “lessons from the past” is not straightforward. Especially in the case of big questions about his…
Climatic and anthropogenic influences on vegetation changes during the last 5000 years in a seasonal dry tropical forest at the northern limits of the Neotropics
Seasonal dry tropical forest (STDF) is a widespread vegetation type in western Mexico. Generally, this type of forest develops in semihumid habitats where lacustrine basins are scarce, preventing documentation of the vegetation history and forest dynamics using a paleoecological approach. Here, we present a palynological record from the Santa Maria del Oro crater lake, located within the distribution area of the STDF and the adjacent dry oak fore…
Novel responses of diatoms in neotropical mountain lakes to indigenous and post-European occupation
A Tale of Maize, Palm, and Pine
The environmental impact of the ancient Maya, and subsequent ecological recovery following the Terminal Classic decline, have been the key foci of research into socio-ecological interactions in the Yucatán peninsula. These foci, however, belie the complex pattern of resource exploitation and agriculture associated with post-Classic Maya societies and European colonisation. We present a high-resolution, 1200-year record of pollen and charcoal data…
Diatoms in a sediment core from a flood pulse wetland in Malaysia record strong responses to human impacts and hydro‐climate over the past 150 years
Rapid development and climate change in southeast Asia is placing unprecedented pressures on freshwater ecosystems, but long term records of the ecological consequences are rare. Here we examine one basin of Tasik Chini (Malaysia), a UNESCO‐designated flood pulse wetland, where human disturbances (dam installation, iron ore mining, oil palm and rubber cultivation) have escalated since the 1980s. Diatom analysis and organic matter geochemistry (δ …
An analysis of the likely success of policy actions under uncertainty
Seasonality of Holocene hydroclimate in the Eastern Mediterranean reconstructed using the oxygen isotope composition of carbonates and diatoms from Lake Nar, central Turkey
A positive shift in the oxygen isotope composition ( δ 18 O) of lake carbonates in the Eastern Mediterranean from the early to late Holocene is usually interpreted as a change to drier (reduced precipitation and evaporation (P/E)) conditions. However, it has also been suggested that changes in the seasonality of precipitation could explain these trends. Here, Holocene records of δ 18 O from both carbonates and diatom silica, from Lake Nar in cent…
Human impact on the hydroenvironment of Lake Parishan, SW Iran, through the late-Holocene
A multiproxy record from Lake Parishan, SW Iran, shows human impact on the lake and its catchment over the last 4000 years. The Parishan record provides evidence of changes in lake hydrology, from ostracod, diatom and isotope analyses, that are directly linked to human activity in the catchment; recorded by pollen and charcoal and supported by regional archaeological and historical data. The lake ostracod fauna is particularly sensitive to human-…
Diatom response to Asian monsoon variability during the Late Glacial to Holocene in a small treeline lake, SW China
Analyses of diatoms, grain size, magnetic susceptibility, total organic carbon, and total nitrogen were applied to a 9.26 m long sediment core, spanning the last 12.2 kyr, from a small treeline lake (Tiancai Lake, ~3898 m a.s.l.) in southwest China. Diatom assemblages are dominated by Cyclotella distinguenda, Aulacoseira species, and small fragilarioid taxa, all of which are sensitive to changes in water pH and light conditions that are probably …
A record of Holocene summer-season palaeohydrological changes from the southern margin of Chihuahua Desert (Mexico) and possible forcings
Proxy records of runoff, lake water salinity and aeolian activity, reconstructed by analyzing the concentrations of Ti, Ca and Zr/Ti in the sediments of palaeolake Las Cruces, provide information about millennial-scale summer season palaeohydrological changes at the southern margin of Chihuahua Desert over the last 8.4 cal. kyr BP. The data indicate generally higher-than-average runoff between c. 8.4 and 5 cal. kyr BP, correlative to the early Ho…

A 3 m core from the New River Lagoon, adjacent to the Maya city of Lamanai, Northern Belize, contains a continuous record of vegetation change between c. 1500 bc and ad 1500. Inferred changes in forest abundance and plant community assemblage build on previous palaeolimnological analysis of the same core reported by Metcalfe et al. (2009). A near-complete, abundant record of Zea mays grains provides a detailed account of field-based agriculture l…
P1-476 An assessment of the concentration-related prognostic value of cardiac troponin I in 1285 patients following acute coronary syndrome
Introduction The British Cardiac Society, in 2004, redefined myocardial infarction by troponin concentration: cTnI ≤0.06 μg/l (unstable angina), cTnI >0.06 μg/l to 0.06 and 80 years (3.30, 3.50 to 5.06), peripheral vascular disease (1.50, 1.16 to 1.94), heart failure (1.36, 1.05 to 1.83), diabetes (1.68, 1.36 to 2.07), severe LV dysfunction (1.50, 1.00 to 2.21) and creatinine per 10 μmol/l (1.65, 1.02 to 1.08), whereas ages 50 to 60 years (0.55, …
Climate variability over the last two millennia in the North American Monsoon region, recorded in laminated lake sediments from Laguna de Juanacatlán, Mexico
High-resolution titanium (Ti) data obtained using an ITRAX XRF core scanner from a laminated sediment core from the Laguna de Juanacatlán, western central Mexico yield a unique high-resolution record of runoff (precipitation) change for the last 2000 years. In the absence of reliable, long-term meteorological records, comparison of the Ti data with information from the rich Spanish colonial period archives and the post-Independence period, confir…
Sedimentary record of late-Holocene relative sea-level change and tectonic deformation from the Guerrero Seismic Gap, Mexican Pacific Coast
Studies of the coastal sedimentary record have allowed both the reconstruction of relative sea-level changes and the determination of local rates and magnitudes of tectonic deformation, particularly in tectonically active areas. Despite their successful use elsewhere, studies of this type are much less common for the Mexican Pacific coast, which parallels the Cocos-North America subduction plate boundary. Stratigraphic, geochemical and microfossi…
Integrated diatom-pollen based Holocene environmental reconstruction of lake Las Margaritas, eastern savannas of Colombia
A multiproxy analysis that includes diatoms, pollen, element geochemistry, carbon content analysis, and radiocarbon dates was carried out on a core from Las Margaritas (3023‘N, 73 0 26’W) in order to reconstruct environmental and climatic change. This lake is hydrologically closed and is located in the transitional area between the Amazonian rainforest and the savannas of the eastern part of Colombia. It therefore offers an excellent opportunity …

Modelling Acid Deposition and the Possible Effects of Emission Controls
GEOGRAPHERS HAVE PLAYED AN IMPORTANT part in highlighting the effects of acid deposition on aquatic ecosystems and on built environments (see Battarbee and Cooke pp. 353-366). At the same time a major, yet largely separate, field of research has been the development of models to investigate the long-range transport of the acidic gases (SOx, NOy, NHx) which result in what has been known as acid rain. Initially, the aim of these models was to inves…
