In a published paper, a method for testing the correlation between two discrete characters was presented and applied to test whether in butterfly larvae origins of gregariousness are concentrated to lineages with aposematic coloration. The relationship was found to be nonsignificant. However, the butterfly data on which the test was applied had been compiled in another study to investigate evolutionary sequences and was biased, because there was an overrepresentation of aposematic, as compared… Expand
Phylogenies and the Comparative Method: A General Approach to Incorporating Phylogenetic Information into the Analysis of Interspecific Data
TLDR
A generalized linear model (GLM) is presented for the analysis of comparative data, which can be used to address questions regarding the relationship between traits or between traits and environments, the rate of phenotypic evolution, the degree of phylogenetic effect, and the ancestral state of a character.

CONDUCTING PHYLOGENETIC COMPARATIVE STUDIES WHEN THE PHYLOGENY IS NOT KNOWN
  • E. Martins
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1996
TLDR
A method is proposed to conduct phylogenetic analyses of comparative or interspecific data when the true phylogeny is not known and the mean of this distribution is proposed as a reasonable estimate of the true evolutionary statistic of interest. Expand
A COMPARISON OF TWO METHODS TO STUDY CORRELATED DISCRETE CHARACTERS ON PHYLOGENETIC TREES
Abstract — We use a simulation approach to study two methods proposed for the analysis of correlated discrete characters on cladograms, the concentrated changes test (CCT) and the contingent statesExpand
Evolutionary Diversification of Continuous Traits: Phylogenetic Tests and Application to Seed Size in the California Flora
TLDR
The F-test for trait variances provides a simple, phylogenetically structured approach to test for differences in rates of phenotypic diversification and could also provide a valuable tool in the study of adaptive radiations. Expand
Analysis of comparative data using generalized estimating equations.
TLDR
A new method is introduced, based on the use of generalized estimating equations (GEE), for the analysis of comparative data, to incorporate a correlation matrix that specifies the dependence among observations in the phylogenetic tree of the studied species. Expand
TAXON SAMPLING, CORRELATED EVOLUTION, AND INDEPENDENT CONTRASTS
  • D. Ackerly
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2000
TLDR
The simulations showed that random samples, with respect to the traits under consideration, provide statistically robust estimates of trait correlations, but exact significance tests are highly dependent on appropriate branch length information; equal branch lengths maintain lower Type I error than alternative topological approaches, and adjusted critical values of the independent contrast correlation coefficient are provided.

A phylogenetic analysis of the Gruiformes (Aves) based on morphological characters, with an emphasis on the rails (Rallidae).
TLDR
In the species–level analysis of modern Grues, special efforts were made to limit the analytical impacts of homoplasy related to flightlessness in a number of rallid lineages, and relationships among ‘crakes’ remain poorly resolved. Expand
Correlated evolution in fig pollination.
TLDR
This is the first comparative study of correlated evolution between figs and their pollinators based on molecular phylogenies of both lineages and shows that interacting trait correlations are stronger than within-lineage allometric relationships. Expand
COVARIATION OF DEFENSIVE TRAITS IN TIGER BEETLES (GENUS CICINDELA): A PHYLOGENETIC APPROACH USING mtDNA
TLDR
This study of character covariation clarifies earlier analyses of the adaptive significance of benzaldehyde defense, which were inconclusive without a phylogenetic hypothesis. Expand
TESTING FOR UNEQUAL AMOUNTS OF EVOLUTION IN A CONTINUOUS CHARACTER ON DIFFERENT BRANCHES OF A PHYLOGENETIC TREE USING LINEAR AND SQUARED‐CHANGE PARSIMONY: AN EXAMPLE USING LESSER ANTILLEAN ANOLIS LIZARDS
  • M. Butler, J. Losos
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1997
TLDR
Results confirm that P‐values for tests using ancestor reconstruction methods should be assessed via simulation rather than from standard statistical tables, and suggest how to investigate the robustness of the hypothesis test by varying the reconstruction methods or simulation parameters. Expand

PATTERNS OF VARIATION IN LEVELS OF HOMOPLASY
TLDR
There is no significant difference between plant and animal data sets in the amount of homoplasy when the relationship between consistency index and number of taxa is taken into account, although there are still too few molecular studies to be confident of this result. Expand
IN SEARCH OF HOMOPLASTIC TENDENCIES: STATISTICAL INFERENCE OF TOPOLOGICAL PATTERNS IN HOMOPLASY
  • M. Sanderson
  • Mathematics, Medicine
  • Evolution; international journal of organic evolution
  • 1991
TLDR
The present findings do not provide compelling evidence for the existence of “tendencies” in homoplasy, at least among characters used to reconstruct phylogenies, and should be sought elsewhere, probably among a class of characters defined a priori on a structural or functional basis. Expand
A METHOD FOR TESTING THE CORRELATED EVOLUTION OF TWO BINARY CHARACTERS: ARE GAINS OR LOSSES CONCENTRATED ON CERTAIN BRANCHES OF A PHYLOGENETIC TREE?
  • W. Maddison

TLDR
Simulations suggest that biases resulting from errors in parsimony reconstructions of ancestral states are not extreme, and are in fact not extreme. Expand
The Relationship between Concealed Ovulation and Mating Systems in Anthropoid Primates: A Phylogenetic Analysis
TLDR
There is a linkage between absence of ovulation signs and monogamy, but the temporal relationship is generally such that the lack of ovulatory signs is more likely to promote monogamy than monogamy is to promote a lack of Ovulatory signs. Expand
EVOLUTION OF GREGARIOUSNESS IN APOSEMATIC BUTTERFLY LARVAE: A PHYLOGENETIC ANALYSIS
TLDR
It is concluded that unpalatability is an important predisposing factor for the evolution of egg clustering and larval gregariousness in butterflies and kin selection is of minor importance for the development of both unpal atability and warning coloration. Expand
CLADISTIC TESTS OF ADAPTATIONAL HYPOTHESES
TLDR
A cladistic viewpoint provides an historical definition of adaptation and an operational ecological test for evolutionary adaptations, and useful to distinguish whether hypotheses about characters identify selection as facilitating: 1) the origin of a character; 2) its maintenance; 3) neither; or 4) both.

PHYLOGENIES AND THE ANALYSIS OF EVOLUTIONARY SEQUENCES, WITH EXAMPLES FROM SEED PLANTS
  • M. Donoghue
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1989
TLDR
A cladistic test of the hypothesis that the evolution of dioecy is favored in animal‐dispersed plants indicates that dioECy may have originated somewhat more often in such lineages, which must largely account for the observed species‐level correlation between dispersal and breeding system. Expand
The benefits of communication between comparative ethology and phylogenetic systematics: a case study using gasterosteid fishes
TLDR
The decline of phylogenetically based explanations of behavioural evolution is mirrored by the decline in the utilization of behavioural data in systematic analyses, and the tendency of many researchers to confuse character maintenance (stasis) with character origin and divergence (evolution). Expand
The systematic position of Antirrhea and Caerois, with comments on the classification of the Nymphalidae (Lepidoptera)
TLDR
The authors suggest that a solution to the seemingly intractable problem posed by nymphalid higher classification can be sought by the application of cladistic analysis to a large data set gathered from all developmental stages, with special emphasis on detailed comparative larval morphology.

SURVIVAL OF DISTASTEFUL INSECTS AFTER BEING ATTACKED BY NAIVE BIRDS: A REAPPRAISAL OF THE THEORY OF APOSEMATIC COLORATION EVOLVING THROUGH INDIVIDUAL SELECTION
  • C. Wiklund, T. Järvi
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1982
TLDR
It is concluded that the belief that kin selection is necessary for the evolution of aposematic coloration depends on the untested assumptioin that distasteful animals are killed during experimental tasting by predators. Expand
