ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...

Control Strategies in Guanine Biocrystallization
Biological guanine crystals produce spectacular photonic phenomena in animals and hold great promise as new, sustainable optical materials. We review how organisms precisely control the structure, morphologies, and resulting optical properties of these crystals using a set of ingenious ‘design’ strategies, including control of pH, template‐directed ...

Food Web Properties and the Type of Invasive Species Make the Ecosystem Vulnerable to Invasion
ABSTRACT Invasive species have long been acknowledged as potentially severe dangers to native ecosystems. Although some work has also been done with empirical food webs, more information is still needed to shed light on the cascading effects of invasive species in aquatic ecosystems.

Continued DDT Persistence in Mississippi River Delta Streams: A Case Study [PDF]
Fish samples representative of several trophic levels were taken from the Wolf and Loosahatchie Rivers of western Tennessee during the early 1980s. Results indicate that DDT, with metabolites DDD and DDE, remains common in fish tissues in these areas and

Altered greenhouse gas emissions in shallow lakes invaded by common carp (Cyprinus carpio)
Abstract Species invasions are among the most important environmental problems facing freshwater ecosystems this century, contributing to biodiversity loss and changes in ecosystem function. Freshwater lakes are an important component of the global carbon cycle and a key source of atmospheric greenhouse gases, yet the consequences of species invasions ...

Impact of improved systems on rice and common carp Cyprinus carpio multitrophic tropical aquaculture, Antananarivo, Madagascar [PDF]
Flooded rice fields are ecosystems favorable to the growth and production of many aquatic organisms. They can even play a major role in the feeding and nutrition of local communities, as a source of self-recruiting species or by supporting the production
