Diversity in the Development of the Neuromuscular System of Nemertean Larvae (Nemertea, Spiralia)
Frontiers in Ecology and Evolution, 2021 In studies on the development of nervous systems and musculature, fluorescent labeling of neuroactive substances and filamentous actin (f-actin) of muscle cells and the subsequent analysis with confocal laser scanning microscopy (CLSM), has led to a ...

A new substrate for sampling deep river macroinvertebrates [PDF]
, 2009 We compared macroinvertebrate communities colonising multiplate samplers constructed from perspex or tempered hardboard (wood) with an alternative artificial substrate constructed from folded coconut fibre matting (coir) enclosed in nylon netting ...
