Effects of climate change and nutrient concentrations on carbon sources for zooplankton in a Tibetan Plateau lake over the past millennium
Autochthonous and allochthonous organic carbon (OC) are important carbon sources for zooplankton in lakes, and changes in the abundance and...

How warming and other stressors affect zooplankton abundance, biomass and community composition in shallow eutrophic lakes
We aimed to investigate the influence of environmental factors and predict zooplankton biomass and abundance in shallow eutrophic lakes. We employed...

Zooplankton Size Structure in the Kolsay Mountain Lakes (Kungei Alatau, Southeastern Kazakhstan) and Its Relationships with Environmental Factors
AbstractThe size structure of zooplankton in Kolsay Lakes was characterized with the use of the values of Clarke W -statistic, ∆-Shannon–Weaver, and...

Identifying invasive Daphnia species by morphological analysis of postabdominal claws in Sierra Nevada alpine lakes
Sedimentary postabdominal claws, among other remains, have been used successfully in paleolimnological studies to reconstruct past environmental...

Effects of Acidic Substances on Ecosystems
Acidic substances, such as sulfur dioxide (SO2), nitrogen oxides (NOX), and their producing acids (sulfuric acid and nitric acid), which are...

A 450-year record of environmental change from Castle Lake, California (USA), inferred from diatoms and organic geochemistry
A 39-cm sediment core from Castle Lake, California (USA) spans the last ~ 450 years and was analyzed for diatoms and organic geochemistry (δ 15 N, δ 13 C,...

Effects of Acidic Substances on Ecosystems
Acidic substances, such as sulfur dioxide (SO2), nitrogen oxides (NOX), and their producing acids (sulfuric acid and nitric acid), which are...

The impact of trout introductions on macro- and micro-invertebrate communities of fishless boreal lakes
Effects of fish introductions on lake ecosystems have long been debated. It has been hypothesized that such effects should be strongest in...

Sedimentary macrofossil records reveal ecological change in English lakes: implications for conservation
Aquatic macrophytes play a key role in providing habitat, refuge and food for a range of biota in shallow lakes. However, many shallow lakes have...

Fossil chironomid assemblages and inferred summer temperatures for the past 14,000 years from a low-elevation lake in Pacific Canada
Fossil midge remains in a sediment core from Lake Stowell, a low-elevation lake in coastal British Columbia, Canada, were used to assess temporal...

The effect of fish stocking on mountain lake plankton communities identified using palaeobiological analyses of bottom sediment cores
The artificial introduction of fish into a naturally fishless lake can effectively modify the food web and trophic status of that lake. We observed...

Catchment biogeochemistry modifies long-term effects of acidic deposition on chemistry of mountain lakes
Using relationships between the composition of precipitation and emission rates of sulphur and nitrogen compounds and dust from 1978 to 2012, we...

Discontinuities in the microfossil record of middle Eocene Lake Messel: clues for ecological changes in lake’s history?
We analysed the sediment and small fish coprolites from the 140-m thick lacustrine sediments of the middle Eocene maar lake Messel using material...

Chaoborus americanus predation influences Bosmina mucro lengths in fishless lakes
Size attributes of the cladoceran taxon Bosmina are known to vary in response to the intensity and dominant type of predation. Using a...

Biogeochemical evidence of eutrophication and metal contamination of Frame Lake, City of Yellowknife, Northwest Territories, Canada
The sediments of Frame Lake, Yellowknife, NWT were examined to evaluate human impact due to urbanization and mining and provide background...

Persistence of clear-water, shallow-lake ecosystems: the role of protected areas and stable aquatic food webs
The roles of both landscape alteration and in-lake processes need to be considered in conservation strategies for shallow lakes in the prairie...

Predation of adult large diving beetles Dytiscus marginalis (Linnaeus, 1758), Dytiscus circumcinctus (Ahrens, 1811) and Cybister lateralimarginalis (De Geer, 1774) (Coleoptera: Dytiscidae) on fish fry
The presented study describes the presence of fish fry in the diet of imagines of large Dytiscidae. The study was conducted between March and...

Reduction of zooplankton communities in small lake outlets in relation to abiotic and biotic factors
The aim of this study was to answer the following questions: (1) which environmental variables, biotic (fish predation) or abiotic factors, have a...

Phantom midge-based models for inferring past fish abundances
We sampled living and subfossil phantom midge (Diptera: Chaoboridae) larvae from surface sediments of 21 small lakes in Southern Sweden to examine...

Evidences of zooplankton vertical migration in stocked and never-stocked alpine lakes in Gran Paradiso National Park (Italy)
Zooplankton vertical migration was described in four high altitude lakes in Gran Paradiso National Park (Northern Italy) during 2008 summertime. The...
