Abstract:
Downstream-migrating Anguilla celebesensis eels were predominant relative to Anguilla marmorata in October, November, December, January and February (75.9-92%), while no A. celebesensis occurred and A. marmorata were predominant in May and July (96-100%), at the outlet of Poso Lake, Sulawesi Island, Indonesia. Merging these results with those from published data suggests that most A. celebesensis start downstream migration during the early to middle rainy season, and A. marmorata migrate almost year-round with a peak from the late rainy to middle dry season.

Sum and Difference OpAmps
A summing amplifier, or an adder, utilizes an op-amp to merge multiple input signals into a single output signal. When audio signals are introduced into its input channels, the input resistors initiate currents that traverse feedback resistors, resulting in an output voltage. Applying Kirchhoff's current...
