Assessment of Aquatic Invertebrates
2009The assessment of freshwater habitats using benthic macroinvertebrates as a proxy indicator of the general ‘health’ of the freshwater environment has a long and illustrious history. This chapter introduces the means of undertaking such assessments. It outlines how and when to sample, the differing strategies used, depending on the questions to be asked

Aspartic proteinases in fishes and aquatic invertebrates
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19881. The literature on molecular properties and physiological role of aspartic proteinases in fishes and aquatic invertebrates has been reviewed. 2. Pepsins have not been detected in invertebrates, and apparently cathepsin D, as well as other cathepsins, act both as digestive and lysosomal enzymes in many of these animals.

Pro‐oxidant and antioxidant processes in aquatic invertebrates
Annals of the New York Academy of Sciences, 2014Most aquatic organisms behave as conformers with respect to environmental variables, including changes in O2 availability. Aquatic species that show tolerance to hypoxia/anoxia or hyperoxia can be excellent models for investigating physiological and biochemical adaptations that deal with changing O2 and consequent changes in metabolic rate and ...

Aquatic Invertebrate Dormancy and Medicine
2019Aquatic organism dormancy has interesting medical applications, which include dormancy in parasite species, dormancy in intermediate hosts of parasites, and several diseases that seem to present a kind of dormancy. Among these, the most remarkable is the state of dormancy in some types of cancer, one of the most serious human diseases.

Volume regulation in aquatic invertebrates
Journal of Experimental Zoology, 1981AbstractVolume regulation in marine and estuarine invertebrates is usually assessed by the extent of restoration of original weight following a salinity transfer. However, volume regulation also includes the limitation of osmotic water movements. Mechanisms of volume regulation include (1) reduction of permeability of the body wall to water, reducing ...

Respiratory faculties of aquatic invertebrates
2019Abstract This chapter introduces the ‘who has what’ in terms of respiratory organs for major water-breathing invertebrate groups. It begins with sponges and cnidarians—groups that have no recognizable respiratory faculty—and continues through the bilaterian lineage, pointing out how bits and pieces of a respiratory faculty accumulate ...

Sample Preparation for Proteogenomics of Aquatic Invertebrates
Aquatic invertebrates account for many known animal species. Their diversity of form and lifestyle and adaptation to various habitats are outstanding. Several of these animals are considered reliable indicators of watershed health and are thus frequently used as environmental sentinels in ecotoxicology programs.Christine, Almunia +2 more

Sampling invertebrates: aquatic environments
1998Abstract This chapter outlines the principles and conditions for use of some of the techniques used to sample invertebrates from aquatic habitats, both fresh¬ water and marine. Many of the principles and apparatus are similar for the two habitats, but there are numerous differences due to scale and ease of access.

Aquatic invertebrates of the Coastal Plain
1993The Coastal Plain of Suriname, located at 0-11 m above sea level, covers about 18,000 km2 and is divided into the Old Coastal Plain with Pleistocene soils of clays and fine sands, and the Young Coastal Plain with Holocene soils of mainly clays with some beach ridges. The fine sands and clays of the Coastal Plain are probably mainly of Amazonian (Andean)
