Seabird species world‐wide are integral to both marine and terrestrial environments,
connecting the two systems by transporting vast quantities of marine‐derived nutrients and …

This paper provides an overview of stable isotope analysis (H, C, N, O, Si) of the macro-and
microscopic remains from aquatic organisms found in lake sediment records and their …

Organic fertilizers have the capacity to alter the nitrogen isotopic composition of plants.
Camelid dung and seabird guano are two potentially important fertilizers in the agricultural …

Numerous environmental pressures have precipitated long-term population reductions of
many insect species. Population declines in aerially foraging insectivorous birds have also …

Eutrophication is perhaps the most pervasive form of pollution. Here we first review its effects
on lake ecosystems based largely on modern ecological investigation. The longer time scale …

The lack of long-term monitoring data for many wildlife populations is a limiting factor in
establishing meaningful and achievable conservation goals. Even for well-monitored …

Lakes are a dominant feature of the Arctic landscape and a focal point of regional and global
biogeochemical cycling. We collected a sediment core from a High Arctic Lake in …

Considerable progress has been made using experimental approaches and spatial surveys
to better understand and manage shallow lake ecosystems. Meanwhile, research on the …

The stable isotopic composition of fossil resting eggs (ephippia) of Daphnia spp. is being
used to reconstruct past environmental conditions in lake ecosystems. However, the …

Remains of chironomid larvae, especially their strongly sclerotized head capsules, can be
found abundantly and well preserved in most lake sediment records. These remains mainly …
