Statisticians work with figures, whereas scientists work with estimated quantities. Every direct (physical) measurement has some degree of uncertainty. Single numbers pose no problems, and an implied range can always be specified. Difficulties arise

Concepts in science have an important role: They delimit and specify objects, activities, processes, and abstract entities. When terms are diffuse, mean different things to different persons, and lead more to qualifications than demarcation, they cea

Sorting of freshwater invertebrate samples is best done while the animals are still alive. However, sorting in the field generally means less overall sampling can be done in the allotted time. Placing samples under cold conditions has been the tradi

The systematics of many groups of organisms has been based on the adult stage. Morphological transformations that occur during development from the embryonic to the adult stage make it difficult (or impossible) to identify a juvenile (larval) stage i

The biogeography of organisms, particularly those with complex lifestyles that can affect dispersal ability, has been a focus of study for many decades. Most Hydrachnidia, commonly known as water mites, have a parasitic larval stage during which disp

Visualization and representation are two processes at the core of basic biodiversity studies. Visualization involves the examination, sorting, and evaluation of similarities and differences among specimens by specialists who then assign them to the s

Public molecular databases are fundamental tools for modern taxonomic studies whose usefulness rely on the soundness of the data within them. Here, we study potential errors that can arise along the data pipeline from sampling, specimen identificatio

This is an excellent monograph on a group of animals largelyunknown to the general public: the water mites. It has detailedinformation on the 273 water mite species recorded in theNetherlands to date, a key for identification, data on phenologyand di
