View Resource Laboratory Transmission of Xanthomonas Campestris Pv. Raphani by a Tardigrade (Parachela = Macrobiotidae)

This Florida Entomologist scholarly article, written by Thomas G. Benoit, Jennifer Locke, James R. Marks and Clark W. Beasley, (3-page PDF) investigates the ability of tardigrades, also known as water bears, to transmit phytopathogenic bacteria to suitable plant hosts where they could then cause disease. The study showed that when tardigrades were inoculated with Xanthomonas campestris pv....

View Resource The Incredible Water Bear

This image-rich Micscape Magazine article explores how water bears can be found almost everywhere yet are still unknown to almost everybody, why there are relatively few light microscope photographs of water bears in the literature and on the Web, and how light microscopy can outperform scanning electron microscopy when viewing these animals. It includes a list of historical references, early...

View Resource What a Couple of Dimensions Can Do For You: Comparative Developmental Studies Using 4D Microscopy, Examples from Tardigrade Development

This Integrative and Comparative Biology scholarly paper (11-page PDF) presents a sophisticated method of microscopy, 4D microscopy (3D time-lapse microscopy), which records the entire development of an embryo and allows detailed analyses of events such as cleavage, cell migration, cell death (apoptosis), and cell differentiation during development. Using tardigrade development as an example,...

View Resource Tardigrades as Environmental Indicators

This essay was written by Amber, a high school senior who won the Young Naturalist Award in 2001 for her research on tardigrades (also known as water bears) as environmental bioindicators. Amber discusses how she became interested in tardigrades and her project, including sampling techniques, results, and her trip to Greenland with 15 prestigious tardigradologists from around the world. The...

View Resource Dry Up Baby! Anhydrobiosis

This lab activity offers students an exploration into the survival mechanisms of organisms inhabiting the extreme environmental conditions of the Polar Regions. Students will design experiments using Tardigrades and Rotifers to expand their knowledge and understanding of normal behavior followed by experiments to explore anhydrobiosis, an adaptation of psychrophiles. The resource, available in...
