Growth of Corophium volutator under laboratory conditions.
Temperature-dependent growth is an important factor in the population model of Corophium volutator that was developed to translate responses in a 10-day acute bioassay to ecological consequences for the population. The growth rate, however, was estimated from old data, based on a Swedish population. Therefore, new growth rates are estimated herein from two experiments using Corophium volutator....
متن کاملDiscrimination, previous experience and substrate selection by the amphipod Corophium.
The experiments reported below were undertaken to give more information about why animals prefer one habitat or substrate to another. They are a continuation of work already reported on substrate selection by Corophium volutator (Meadows, 1964 a, b, c). Consider an experiment in which animals may choose between two substrates, A and B, and in which at equilibrium 75 % are found in A and 25 % in...
متن کاملClimate change, parasitism and the structure of intertidal ecosystems.
Evidence is accumulating rapidly showing that temperature and other climatic variables are driving many ecological processes. At the same time, recent research has highlighted the role of parasitism in the dynamics of animal populations and the structure of animal communities. Here, the likely interactions between climate change and parasitism are discussed in the context of intertidal ecosyste...
متن کاملComparison of laboratory and in situ sediment bioassays using Corophium volutator.
Bioassays with the marine amphipod Corophium volutator were performed simultaneously in situ and in the laboratory using sediments sampled from the in situ locations. In most cases, the in situ response was significantly higher compared to the laboratory response. This difference was not caused by direct influence of the use of the field chamber on Corophium sp., nor was the difference caused b...
متن کاملMacrobenthos abundance and distribution on a spatially patterned intertidal flat
Natural ecosystems can show regular spatial vegetation patterns, which develop from small-scale ecological interactions. Some studies suggest that grazers can play a major role in controlling vegetation distribution in ecosystems with regular vegetation patterns, but the distribution of grazers and the effects of grazing on vegetation in spatially patterned ecosystems remains poorly understood....
