Testing hypotheses about ecological specialization using phylogenetic trees.
It is often assumed that ecological specialization represents an evolutionary "dead-end" that limits further evolution. Maximum-likelihood (ML) analyses on phylogenies for 15 groups of phytophagous insects revealed that high transition rates both to and from specialization occurred, but that the mean ratio of rates was significantly biased toward a higher rate to specialization. Here we explore...
متن کاملTesting Hypotheses with Induction Trees
Data mining has brought a new philosophy in data analysis that is primarily driven by computational efficiency and predictive performance. In this paper we attempt to show that while this new philosophy opens new horizons, these new techniques may themselves gain much when coupled with traditional statistical reasoning. For example, I recently introduced some sociologists of the University of G...
متن کاملPhylogenetic estimates of speciation and extinction rates for testing ecological and evolutionary hypotheses.
Phylogenies are used to estimate rates of speciation and extinction, reconstruct historical diversification scenarios, and link these to ecological and evolutionary factors, such as climate or organismal traits. Recent models can now estimate the effects of binary, multistate, continuous, and biogeographic characters on diversification rates. Others test for diversity dependence (DD) in speciat...
متن کاملTesting hypotheses about sun-climate complexity linking.
We reexamine observational evidence presented in support of the hypothesis of a sun-climate complexity linking by N. Scafetta and B. J. West, Phys. Rev. Lett. 90, 248701 (2003)10.1103/PhysRevLett.90.248701, which contended that the integrated solar flare index (SFI) and the global temperature anomaly (GTA) both follow Lévy walk statistics with the same waiting-time exponent mu approximately 2.1...
متن کاملComment on ‘ ‘ Testing Hypotheses about Sun - Climate
Rypdal and Rypdal (RR) [1] assert that the hypothesized linking between the Sun and climate complexity, first suggested by Scafetta and West (SW) [2] and developed in subsequent publications [3–6], is not supported by data. However, RR employed Lévy Flight noise in their analysis instead of the Lévy Walk (LW) signal used by SW. In fact, RR focused on the statistics of increments while SW focuse...
