This Test Guideline is designed to be used for assessing the effects of chemicals on the reproductive output of the enchytraeid worm, Enchytraeus albidus Henle 1873, in soil.
This Test Guideline is designed to be used for assessing the effects of chemicals on the reproductive output of the enchytraeid worm, Enchytraeus albidus Henle 1873, in soil. Adult enchytraeid worms are exposed to a range of concentrations of the ...
This Test Guideline describes a method to assess the effects of chemical substances in soil on the reproductive output of the soil mite species Hypoaspis (Geolaelaps) aculeifer Canestrini (Acari: Laelapidae). It can be used for water soluble or ...
This Test Guideline describes a method to estimate the developmental toxicity of a test chemical to the dung dwelling life stages of dung-dependent dipteran species. Two test species can be used. The test chemical is mixed with bovine faeces, to ...
Pesticide usage is increasing worldwide and considered among the main factors contributing to the global decline in biodiversity. This Research Topic provides an overview of the state-of-knowledge regarding non-target effects of herbicides, fungicides, insecticides and rodenticides on a variety of ecosystem functions and organisms. Taxa covered in the contributions include algae, amphibians, aquatic fungi, aquatic insects, bats, bumblebees, butterflies, earthworms, enchytraeids, honeybees, plants, rodents and soil microorganisms. The papers also highlight many gaps in our understanding of non-target effects of pesticides and their consequences for biodiversity and functions of various ecosystems. Overall, it became clear that priorities for future work on pesticides and their effects should more focus on investigating or simulating realistic field situations, i.e., multiple applications of pesticides during the growing season including their temporal and spatial interactions with fauna and flora.
This guidance document was originally published in 2012 and updated in 2018 to reflect new and updated OECD test guidelines, as well as reflect on scientific advances in the use of test methods and assessment of the endocrine activity of chemicals.
Terrestrial isopods (woodlice) are the only group of crustaceans fully adapted to life on land and with about 3,700 species known at present represent the largest suborder of Isopoda. They occur in almost any kind of terrestrial habitat, from littoral to high mountains, from forests to deserts, with some species adapted to live in subterranean environments and others secondarily having returned to water. Woodlice are particularly important from a biogeographical and an ecological point of view, since they have limited dispersal ability, are often endemic to small geographic areas, and are extremely diverse ecologically.ÿThey also represent en excellent model group of animals to study the physiological adaptations related to the transition from an aquatic to a terrestrial way of life. This special issue of ZooKeys includes a collection of 20 papers presented during the 8th International Symposium on Terrestrial Isopod Biology, which was held at Bled, Slovenia from 19th to 23rd June 2011. Contributions address a wide range of topics related to terrestrial isopods, such as systematics, biogeography, morphology, physiology, molecular biology, microbiology, and ecology. Two contributions are related to the state of the art and future perspectives on biomineralizations in crustaceans and ecotoxicology in soil fauna. This special issue will be of great value for anyone interested in the biology of crustaceans in general and of terrestrial isopods in particular, stimulating future research on this unique group of animals.
Founded on the paradox that all things are poisons and the difference between poison and remedy is quantity, the determination of safe dosage forms the base and focus of modern toxicology. In order to make a sound determination there must be a working knowledge of the biologic mechanisms involved and of the methods employed to define these mechanisms. While the vastness of the field and the rapid accumulation of data may preclude the possibility of absorbing and retaining more than a fraction of the available information, a solid understanding of the underlying principles is essential. Extensively revised and updated with four new chapters and an expanded glossary, this fifth edition of the classic text, Principles and Methods of Toxicology provides comprehensive coverage in a manageable and accessible format. New topics include 'toxicopanomics', plant and animal poisons, information resources, and non-animal testing alternatives. Emphasizing the cornerstones of toxicology-people differ, dose matters, and things change, the book begins with a review of the history of toxicology and followed by an explanation of basic toxicological principles, agents that cause toxicity, target organ toxicity, and toxicological testing methods including many of the test protocols required to meet regulatory needs worldwide. The book examines each method or procedure from the standpoint of technique and interpretation of data and discusses problems and pitfalls that may be associated with each. The addition of several new authors allow for a broader and more diverse treatment of the ever-changing and expanding field of toxicology. Maintaining the high-quality information and organizational framework that made the previous editions so successful, Principles and Methods of Toxicology, Fifth Edition continues to be a valuable resource for the advanced practitioner as well as the new disciple of toxicology.
