The Hydrobia ulvae-Maritrema subdolum association: influence of temperature, salinity, light, water-pressure and secondary host exudates on cercarial emergence and longevity.
The effects of environmental factors and exudates from the amphipod Corophium volutator on the emergence of Maritrema subdolum cercariae (Digenea: Microphallidae) from the snail Hydrobia ulvae were investigated in the laboratory. Increasing the temperature (15 to 25 degrees C) caused an overall 11-fold increase in emergence rate under varying salinities (24 to 36 per thousand). The effect of sa...
متن کاملGrowth 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 کاملThe Hydrobia ulvae-Maritrema subdolum association: cercarial emergence controlled by host activity.
The release of Maritrema subdolum cercariae (Digenea: Microphallidae) from the marine mud snail Hydrobia ulvae is significantly affected by temperature, salinity, light and exudates from the second intermediate amphipod host. Based on (i) previously published data on temperature-salinity dependent H. ulvae activity, (ii) new experimental data on H. ulvae activity in light and darkness as well a...
متن کاملSocioeconomic Factors Associated With Mortality Rate Caused by Severe Stroke
Background: Stroke is one of the most important causes of disability-adjusted life years lost. Low socioeconomic status is associated with increased stroke-related morbidity and mortality. Objective: This study aimed to investigate in-hospital mortality rate caused by severe cases of ischemic and hemorrhagic stroke and its relationship with patients’ socioeconomic status. Materials and Method...
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...
