Quantitative Trait Loci Mapping and The Genetic Basis of Heterosis in Maize and Rice

GENETICS, 180(3), 1707–1724.

By: A. Franco Garcia *, S. Wang*, A. Melchinger * & Z. Zeng n

MeSH headings : Clinical Trials as Topic / methods; Computer Simulation; Data Interpretation, Statistical; Disease Progression; Endpoint Determination; Humans; Likelihood Functions; Statistics, Nonparametric; Survival Analysis

Positive interactions among competitors can produce species-rich communities

ECOLOGY LETTERS, 11(9), 929–936.

By: K. Gross n

author keywords: facilitation; interaction component; resource competition; species coexistence; theoretical ecology
MeSH headings : Animals; Biodiversity; Competitive Behavior; Ecology; Models, Biological; Population Dynamics
TL;DR: It is shown that positive interactions among resource competitors can produce species-rich model communities supported by a single limiting resource and that focusing on the net interaction between species may conceal important coexistence mechanisms when species simultaneously engage in both antagonistic and positive interactions.

MeSH headings : Algorithms; Data Interpretation, Statistical; Humans; Randomized Controlled Trials as Topic / statistics & numerical data; Sampling Studies; Statistics, Nonparametric; Treatment Outcome
TL;DR: App appealing to the theory of semiparametrics is led naturally to a characterization of all treatment effect estimators and to principled, practically feasible methods for covariate adjustment that yield the desired gains in efficiency and that allow covariate relationships to be identified and exploited while circumventing the usual concerns.
