The diatom record of V95-2P, a 7.6 m long sediment core collected from 67 m depth, is the first from the east central portion of Lake Victoria. A soil horizon developed at the coring site shortly before 12,400 14C yr BP due to a lakewide desiccation…

Diatom analysis of a varved sediment core from Elk Lake, Minnesota documents important natural and human- caused shifts in primary productivity at decadal scales for the past 1500 years. Interpretations from a perspective of planktic diatom seasonal…

This paper introduces the background and main results of a research project aimed at unravelling the paleolimnological and paleoclimatological history of Lago Puyehue (40 degrees S, Lake District, Chile) since the Last Glacial Maximum (LGM), based…

A 2200-yr long, high-resolution approximately 5 yr) record of drought variability in northwest Montana is inferred from diatoms and δ18O values of bio-induced carbonate preserved in a varved lacustrine core from Foy Lake. A previously developed…

A series (N = 12) of short 1 m) sediment cores were collected from meromictic Green Lake in Fayetteville, New York to investigate potential anthropogenic impacts on the watershed during historic time and environmental change over the past ~ 2,500…

Analyses of plant macrofossils, testate amoebae and humification have been carried out on a 2800-year core from Tore Hill Moss, a raised bog in the Strathspey region of Scotland. All three analyses were carried out at the same 4cm intervals allowing…

A continuous record of lacustrine sedimentation capturing the entire full-glacial period was obtained from Arolik Lake in the Ahklun Mountains, southwestern Alaska. Fluctuations in magnetic susceptibility (MS), grain size, organic-matter (OM)…

This paper presents the ecological modelling instrument BLOOM/GEM and several applications to the southern North Sea, including a 3-dimensional model validation. The current instrument and its predecessors have been used since the 1980s for…

A survey to inventory the natural enemies of the horse-chestnut leafmining moth, Cameraria ohridella Deschka and Dimic (Lepidoptera, Gracillariidae) and to evaluate their relative abundance, was conducted from 2001 through 2003 in Lombardy, northern…

Lake Nabugabo is widely known as the home of endemic cichlid fishes, but virtually nothing has been published regarding the limnological setting in which those species evolved during the late Holocene. Analysis of a 2.7 m long sediment core…

We present the first high-resolution alkenone-derived sea surface temperature (SST) reconstruction in the southeast Pacific (Ocean Drilling Program Site 1233) covering the major part of the last glacial period and the Holocene. The record shows a…
-
A high-resolution, independent pollen-inferred paleoclimate record and direct algal seasonality data from the actual time of sediment deposition are used to interpret the high-resolution diatom and chrysophyte record of varved Lake Mina,…

The South African abalone cultivation industry has developed rapidly and is now the largest producer outside Asia.With a rapid decline in wild abalone fisheries, farming now dominates the abalone export market in South Africa. Kelp (Ecklonia maxima)…

We present a Bayesian hierarchical multinomial regression model (Bummer) for organism-based quantitative paleoenvironmental reconstruction. The model is based on the classical (direct) approach to calibration and on careful statistical environmental…

Iron is an essential trace metal and a limiting factor for microalgal growth, but bioavailable dissolved iron concentrations in seawater are low. Microalgal blooms have frequently occurred in coastal areas under such iron limitation accompanied by…

Lagoons are highly productive areas representing more than 50% of the coastline area in Languedoc-Roussillon (South of France, Mediterranean sea). These lagoons are very different in their environmental conditions, human influences, eutrophication…

Abstract The Delaware River and Bay Estuary is one of the major urbanized estuaries of the world. The 100-km long tidal river portion of the estuary suffered from major summer hypoxia in the past due to municipal and industrial inputs in the urban…

The major nutrients nitrate and phosphate have one of the strongest correlations in the sea, with a slope similar to the average nitrogen (N) to phosphorus (P) content of plankton biomass (N/P = 16:1). The processes through which this global…

Lake Võrtsjärv (270 km2, mean depth 2.8 m, Estonia) is an eutrophic and turbid lake (Secchi depth 0.5-1 m) with a high nutrient load (total nitrogen 1-2 mg N l(-1), total phosphorus approximately 50 microg P l(-1)) leading to a highly productive…
