Mating Preferences of the Gynogenetic Amazon Molly Differ Between Populations Sympatric with Different Host Species
Gynogenetic species rely on sperm from heterospecifics for reproduction but do not receive genetic benefits from mating because none of the paternal genome is incorporated into offspring. The gynogenetic Amazon molly (Poecilia formosa) is a species of hybrid origins that are sympatric with one of the two parent species that provide sperm for reproduction, P. latipinna or P. mexicana. Amazons sh...
متن کاملAmazons is PSPACE-complete
Amazons is a board game which combines elements of Chess and Go. It has become popular in recent years, and has served as a useful platform for both game-theoretic study and AI games research. Buro [2] showed that simple Amazons endgames are NP-equivalent, leaving the complexity of the general case as an open problem. We settle this problem, by showing that deciding the outcome of an n×n Amazon...
متن کاملSimple Amazons Endgames and Their Connection to Hamilton Circuits in Cubic Subgrid Graphs
Amazons is a young board game with simple rules and a high branching factor, which makes it a suitable test-bed for planning research. This paper considers the computational complexity of amazons puzzles and restricted amazons endgames. We rst prove the NP{ completeness of the Hamilton circuit problem for cubic subgraphs of the integer grid. This result is then used to show that solving amazons...
متن کاملGigantic cannibals driving a whole-lake trophic cascade.
Trophic cascades have been a central paradigm in explaining the structure of ecological communities but have been demonstrated mainly through comparative studies or experimental manipulations. In contrast, evidence for shifts in trophic cascades caused by intrinsically driven population dynamics is meager. By using empirical data of a cannibalistic fish population covering a 10-year period and ...
