TLDR
Clear Lake, a small Canadian Shield lake that has been influenced little by human activity, was found to be more productive than expected from chemical and optical properties and geological surroundings, although most of the sodium, potassium, and silica entering the lake is weathered from the terrestrial watershed.Abstract:

Phytochemistry of plants associated with a 400-year-old stand of hemlock at Clear Lake Reserve, Ontario
TL;DR: Several species of higher plants and mushrooms have been surveyed growing under the canopy of old stands of hemlock surrounding Clear Lake near Minden, Ontario as discussed by the authors, and the concentration of phenolic compounds was found to be highest in dying plants in sandy soils in full sunlight and lowest in shaded areas in pots filled with debris.

Environmental tracer analysis of winter profile development in two basins of Shagawa Lake, Minnesota
TL;DR: In this paper, the authors studied the winter profile development of Shagawa Lake in Minnesota and found that heat and solutes released from shelf sediments in the western basin cause convective instability at 8-11 m.

Phosphorus Transport in Subsurface Flow at Beech Forest Stands: Does Phosphorus Mobilization Keep up with Transport?
TL;DR: In this paper, the authors present results of sprinkling experiments with ca. 150mm, 2H labelled, total rainfall conducted at 200m2 plots on hillslopes with slopes between 14° and 28° at three beech forests in Germany in summer and spring.

A Working Model for the Variation in Stream Water Chemistry at the Hubbard Brook Experimental Forest, New Hampshire
TL;DR: In this article, the authors show that during the summer, biologic activity measurably reduces the concentration of nitrate and potassium in stream water, while hydrogen ion, aluminum, and nitrate concentrations are increased.

Nutrient Loss Accelerated by Clear-Cutting of a Forest Ecosystem
TL;DR: The forest of a small watershed-ecosystem was cut in order to determine the effects of removal of vegetation on nutrient cycles, and the cut ecosystem exhibited accelerated loss of nutrients.

Nitrification: importance to nutrient losses from a cutover forested ecosystem.
TL;DR: The nitrate concentration (weighted average) in stream water from an experimentally deforested watershed increased from 0.9 milligram per liter before removal of the vegetation to 53 milligrams per liter 2 years later.

Rate of chemical weathering of silicate minerals in New Hampshire
TL;DR: In this article, the losses of dissolved Ca, Na, Mg and K have been determined for six small watersheds in New Hampshire during the period 1963-1967, from the rate at which Ca and Na are lost, the steady-state chemical weathering rate is calculated at 800 kg of bedrock-till per hectare per year.
