Translucent windows: How uncertainty in competitive interactions impacts detection of community pattern
Rafael D'Andrea, Annette Ostling, James P O'Dwyer
Trait variation and similarity among coexisting species can provide a window into the mechanisms that maintain their coexistence. Recent theoretical explorations suggest that compe…
Widespread bursts of diversification in microbial phylogenies
Alice Doucet-Beaupré, James P. O'Dwyer
Until recently, much of the microbial world was hidden from view. A global research effort has changed this, unveiling and quantifying microbial diversity across enormous range of…
Cross-scale ecological theory sheds light on the maintenance of biodiversity
James P. O'Dwyer, Stephen J. Cornell
One of the first successes of neutral ecology was to predict realistically-broad distributions of rare and abundant species. However, it has remained an outstanding theoretical cha…
The impact of species-neutral stage structure on macroecological patterns
Rafael D'Andrea, James P. O'Dwyer
Despite its radical assumption of ecological equivalence between species, neutral biodiversity theory can often provide good fits to species abundance distributions observed in nat…
Reinterpreting Maximum Entropy in Ecology: a null hypothesis constrained by ecological mechanism
James P. O'Dwyer, Andrew Rominger, Xiao Xiao
Simplified mechanistic models in ecology have been criticized for the fact that a good fit to data does not imply the mechanism is true: pattern does not equal process. In parallel…
Inferring processes of cultural transmission: the critical role of rare variants in distinguishing neutrality from novelty biases
James P. O'Dwyer, Anne Kandler
Neutral evolution assumes that there are no selective forces distinguishing different variants in a population. Despite this striking assumption, many recent studies have sought to…
Comparing process-based and constraint-based approaches for modeling macroecological patterns
Xiao Xiao, James P. O'Dwyer, Ethan P. White
Ecological patterns arise from the interplay of many different processes, and yet the emergence of consistent phenomena across a diverse range of ecological systems suggests that m…
Epsilon Expansion for Multicritical Fixed Points and Exact Renormalisation Group Equations
J. O'Dwyer, H. Osborn
The Polchinski version of the exact renormalisation group equations is applied to multicritical fixed points, which are present for dimensions between two and four, for scalar theo…
Non-Perturbative Tachyon Potential from the Wilsonian Renormalization Group
James P. O'Dwyer
The derivative expansion of the Wilsonian renormalization group generates additional terms in the effective beta-functions not present in the perturbative approach. Applied to the…
One Mass-Radius relation for Planets, White Dwarfs and Neutron Stars
D. Lynden-Bell, J. P. O'Dwyer
We produce the simple formula for the radius R of a cold body of mass M, (4 pi rho/3)^{1/3} R = I.M^{1/3} / [1+ (M/Mp)^{2/3}], where I is one for white dwarfs with non-relativistic…
