TLDR
In this article, the authors consider some of the ecological interactions and linkages that occur between land and water, and show the need for a comprehensive understanding of the intricate and complicated interactions.Abstract:
prehending the implications of this disposal downstream. The implications of this are more and more evident in the widespread cultural eutrophication of rivers and lakes. Attempts to understand these problems have been based upon information pieced together from separate (independent) aquatic and terrestrial studies. This ignores important linkages, is inadequate, and shows the need for a comprehensive understanding of the intricate and complicated interactions between land and water. The purpose of this paper, then, is to consider some of the ecological interactions and linkages that occur betweenread more

Tangled webs: reciprocal flows of invertebrate prey link streams and riparian zones
TL;DR: Characteristics of reciprocal prey subsidies are reviewed and it is investigated whether reciprocal prey fluxes stabilise linked stream–riparian ecosystems, how landscape context affects the magnitude and importance of subsidies, and how impacts of human disturbance can propagate between streams and riparian zones via these trophic linkages.

Riverine landscapes: taking landscape ecology into the water
John A. Wiens,John A. Wiens +1 more
TL;DR: In this article, the authors focus on the influence of spatial pattern on ecological processes and consider the ecological consequences of where things are located in space, where they are relative to other things, and how these relationships and their consequences are contingent on the characteristics of the surrounding landscape mosaic at multiple scales in time and space.

An ecosystem perspective of alluvial rivers: connectivity and the hyporheic corridor
Jack A. Stanford,James V. Ward +1 more
TL;DR: In this article, the authors show that large-scale (km 3 ) hyporheic zones contain speciose food webs, including specialized insects with hypogean and epigean life history stages (amphibionts) and obligate groundwater species (stygobionts).

A Comparative Analysis of Potential Nitrification and Nitrate Mobility in Forest Ecosystems
TL;DR: In this article, the authors investigated the controls of potential nitrogen mineralization, nitrate production, and nitrate mo- bilization in a wide range of forest ecosystems through a combination of field and laboratory experiments.

Fish invasion restructures stream and forest food webs by interrupting reciprocal prey subsidies
TL;DR: Evidence is reported from a large-scale field experiment in northern Japan that invasion of nonnative rainbow trout interrupted reciprocal flows of invertebrate prey that drove stream and adjacent riparian forest food webs and led to a 65% reduction in the density of riparian-specialist spiders in the forest.

Effects of Forest Cutting and Herbicide Treatment on Nutrient Budgets in the Hubbard Brook Watershed-Ecosystem
TL;DR: Large increases in streamwater concentration were observed for all major ions, except NH4+, SO4 = and HCO3—, approximately five months after the deforestation, and an inverse relationship between sulfate and nitrate concentrations in stream water was observed in both undisturbed and deforested situations.

Polychlorinated biphenyls in the global ecosystem.
TL;DR: Polychlorinated biphenyls are widely dispersed in the global ecosystem, and are powerful inducers of hepatic enzymes which degrade oestradiol, which could account for a large part of the aberration in calcium metabolism which has been observed in many species of birds since the Second World War.

Some chemical observations on post-glacial lake sediments
TL;DR: In this article, the results of a somewhat exploratory investigation of the chemical composition of cores taken from the sediments of a number of lakes of the English Lake District were reported.
