A Simple SEM (Scanning Electron Microscope) Preparation Protocol for Tardigrades

A Simple SEM (Scanning Electron Microscope) Preparation Protocol for Tardigrades

Tardigrades are animals that lend themselves to Scanning Electron Microscopy (SEM), yet the literature is vague about the process of preparing of the animals for the procedure. A simple, step-by-step protocol for the preparation of tardigrades for SEM is provided. The method includes the construction of a

Tardigrades of North America: Influence of Substrate On Habitat Selection

  Journal of the Pennsylvania Academy of Science 83(1): 10-16, 2009 ABSTRACT The patterns of habitat (moss or lichen) selection have been elusive for tardigrades. Samples of habitat were coUected from ten different substrates (species of tree), the nematodes, rotifers, and tardigrades counted, and their distribution, density,
