Signal Functions

We examined the species specificity of the responses to female pheromones by males of Trichogaster trichopterus, the blue gourami, and Trichogaster pectoralis, the snakeskin gourami, sympatric belontiids from Southeast Asia. Using only chemical signals, males of both species discriminated between ripe females and nonripe females, suggesting that the female chemical signal functions in reproduction. Trichogaster trichopterus males also discriminated between and nonripe females and plain water. Two different experimental procedures showed that male T. pectoralis discriminated between chemical cues from conspecific and heterospecific females while male T. trichopterus did not. This asymmetric specificity of male response is consistent with the ecological histories of the experimental stocks. Trichogaster trichopterus used in these experiments came from a population historically isolated from congeneric species, while T. pectoralis came from a population originally sympatic with three congeners.

Scanning Electron

The low-loss electron (LLE) image in the scanning electron microscope (SEM) is useful for the study of uncoated photoresist and some other poorly conducting specimens because it is less sensitive to specimen charging than is the secondary electron (SE) image. A second advantage can arise from a significant reduction in the width of the “penetration fringe” close to a sharp edge. Although both of these problems can also be solved by operating with a beam energy of about 1 keV, the LLE image has the advantage that it permits the use of a higher beam energy and therefore (for a given SEM) a smaller beam diameter. It is an additional attraction of the LLE image that it can be obtained simultaneously with the SE image, and this gives additional information in many cases. This paper shows the reduction in penetration effects given by the use of the LLE image.
