The first record of millipedes (Diplopoda) being regularly used for food by humans (the Bobo people of Burkina Faso) is given, including information on how the millipedes are prepared. The species in question are Tymbodesmus falcatus (Karsch, 1881) and Sphenodesmus sheribongensis (Schiøtz, 1966) (Gomphodesmidae) and an unidentified species of Spirostreptidae. New information on the nutritional ...

In a previous paper we have shown that disalicyli­ denepropanediamine (DSPD), an inhibitor of photo­ synthetic reduction of ferredoxin1, stimulates re ­ labelling of glycollic acid in algal cells2. Further ex­ periments led to the observation that also the excretion of 14C-labelled glycollate is enhanced by DSPD 3. We supposed that the increase of glycollate formation and excretion by DSPD is d...

A consistent population bias to detour a vertical-bar barrier preferentially leftwise during approach to inspect a dummy predator was demonstrated in the poeciliid fish Girardinus falcatus. The asymmetry seems to be due to a preferential use of the lateral visual field of the right eye during fixation of biologically relevant stimuli such as a predator. Viewing tests revealed in fact that fish ...

The mimetic juveniles of a number of carangid fish species resemble plant parts floating near the water surface, such as leaves, seeds and other plant debris. The present study is the first to verify the morphological similarities and ecomorphological relationships between three carangids (Oligoplites saurus, Oligoplites palometa and Trachinotus falcatus) and their associated plant models. Beha...

We studied detour responses of two species of poeciliid fish (Gambusia hoolbroki and Girardinus falcatus) faced with a vertical-bar barrier, through which conspecifics of the same or different sex or a simulated-predator (which induced detour behaviour for predator-inspection responses) were visible. Both species showed a consistent bias to turn leftward when faced with the predator, and a cons...

Trematode cercariae are commonly found in many freshwater gastropods. These cercariae can serve to identify the occurrence of such trematodes as Centrocestus formosanus, Haplorchis taichui, Haplorchoides sp, and Stellantchasmus falcatus, which are important parasites in Chiang Mai Province, Thailand. As the species of these cercariae cannot be identified accurately based on morphology, this stu...
