Ecological variation and niche construction: 1, 2, 3

Part 1 From its most basic expression in grazing and predatory nematodes with differences in morphological and behavioral phenotypes, neurogenic niche construction is nutrient-dependent and pheromone-controlled. One of these two worms has teeth. It also recognizes self vs other differences and eats other worms. “The patterns of synaptic connections perfectly mirror the fundamental differences in Ecological variation and niche construction: 1, 2, 3
