AbstractEach of 32 male, Dendrobates pumilio (red phase) were allowed to establish a territory in one half of a 40 liter aquarium. Each enclosure contained a substrate of Sphagnum, a potted plant, and a water dish. Males occupying the same aquarium were prevented from seeing one another by an opaque barrier. In the first experiment, residents were presented with a conspecific intruder matched for size and color. Based on a numerical index of aggression, residents were consistently dominant over intruders. When reciprocal trials were conducted, the results were reversed (i.e. residents were dominant over males to which they previously had been subordinate). The success of resident males was not influenced by the size of conspecific intruders. In addition, residents consistently dominated a sympatric confamilial intruder (Phyllobates lugubris). Removal experiments revealed that resident males recognize and defend their enclosures after 3, and to a lesser degree, 6 days of isolation. We also examined the effect of territorial markers on the prior residence effect by stepwise removal of the plant and Sphagnum. Residents aggressively defended enclosures in both experiments. When Sphagnum was removed from the resident's enclosures and placed in a previously unused aquaria, 7 of 10 males exhibited dominance over conspecific intruders.

Testing For Selection

Abstract In this paper, we analyze variation in spectral reflectance and color pattern among populations to demonstrate dramatic divergence between four distinct morphs of the mimic poison frog Ranitomeya imitator. We also analyze genetic divergence in d-loop mtDNA sequences between populations. We then use coalescent-based simulations to demonstrate that the high levels of observed phenotypic divergence are not consistent with levels of genetic divergence expected under neutral drift among populations, implying an important role for selection in driving divergence between these populations.

The total synthesis of two decahydroquinoline poison frog alkaloids ent-cis-195A and cis-211A were achieved in 16 steps (38% overall yield) and 19 steps (31% overall yield), respectively, starting from known compound 1. Both alkaloids were synthesized from the common key intermediate 11 in a divergent fashion, and the absolute stereochemistry of natural cis-211A was determined to be 2R, 4aR, 5R, 6S, and 8aS. Interestingly, the absolute configuration of the parent decahydroquinoline nuclei of cis-211A was the mirror image of that of cis-195A, although both alkaloids were isolated from the same poison frog species, Oophaga (Dendrobates) pumilio, from Panama.
