Data from: Phylogenetic eigenvectors and non-stationarity in the evolution of theropod dinosaur skulls

Jose A. F. Diniz-Filho, Davi M. C. C. Alves, Fabricio Villalobos, Manabu Sakamoto, Steve L. Brusatte & Luis M. Bini
Despite the longstanding interest in non-stationarity of both phenotypic evolution and diversification rates, only recently have methods been developed to study this property. Here, we propose a methodological expansion of the Phylogenetic Signal Representation (PSR) curve based on phylogenetic eigenvectors to test for non-stationarity. The PSR is built by plotting the coefficients of determination R2 from Phylogenetic Eigenvector Regression (PVR) models increasing the number of phylogenetic eigenvectors against the accumulated eigenvalues. The PSR curve is...

Data from: Ancestral reconstruction of reproductive traits shows no tendency toward terrestriality in Leptodactyline frogs

Elisa Barreto Pereira, Rosane Garcia Collevatti, Marcelo Nogueira De Carvalho Kokubum, Núbia Esther De Oliveira Miranda & Natan Medeiros Maciel
Background:Traditionally, the evolution of terrestrial reproduction in anurans from ancestors that bred in water has been accepted in the literature. Still, the existence of intermediate stages of water dependency, such as species that lay eggs close to water (e.g., in burrows) instead of in bodies of water, supports the hypothesis of an ordered and gradual evolution in the direction of a more terrestrial form of reproduction. However, this conventional view has recently been challenged for...

Data from: Contemporary and historic factors influence differently genetic differentiation and diversity in a tropical palm

Carolina C. Carvalho, Milton C. Ribeiro, Mauro Galetti & Rosane G. Collevatti
Population genetics theory predicts loss in genetic variability because of drift and inbreeding in isolated plant populations; however, it has been argued that long-distance pollination and seed dispersal may be able to maintain gene flow, even in highly fragmented landscapes. We tested how historical effective population size, historical migration and contemporary landscape structure, such as forest cover, patch isolation and matrix resistance, affect genetic variability and differentiation of seedlings in a tropical palm (Euterpe edulis)...

Data from: Multi-objective optimization for plant germplasm collection conservation of genetic resources based on molecular variability

Shana Schlottfeldt, Maria Emília M. T. Walter, Andre Carlos P. L. F. Carvalho, Thannya N. Soares, Mariana P. C. Telles, Rafael D. Loyola & Jose Alexandre F. Diniz-Filho
Germplasm collections play a significant role among strategies for conservation of diversity. It is common to select a core collection to represent the genetic diversity of a germplasm collection, in order to minimize the cost of conservation, while ensuring the maximization of genetic variation. We aimed to solve two main problems: (1) to select a set of individuals, from an in situ data set, that is genetically complementary to an existing germplasm collection, and (2)...

Data from: Correlation between genetic diversity and environmental suitability: taking uncertainty from ecological niche models into account

José Alexandre F. Diniz-Filho, Hauanny Rodrigues, Mariana Pires De Campos Telles, Guilherme De Oliveira, Levi Carina Terribile, Thannya Nascimento Soares & João Carlos Nabout
The hindcast of shifts in the geographical ranges of species as estimated by ecological niche modelling (ENM) has been coupled with phylogeographical patterns, allowing the inference of past processes that drove population differentiation and genetic variability. However, more recently, some studies have suggested that maps of environmental suitability estimated by ENM may be correlated to species' abundance, raising the possibility of using environmental suitability to infer processes related to population demographic dynamics and genetic variability....

Data from: Phylogenetic uncertainty revisited: implications for ecological analyses

Thiago Fernando Rangel, Robert K. Colwell, Gary R. Graves, Karolina Fučíková, Carsten Rahbek & José Alexandre F. Diniz-Filho
Ecologists and biogeographers usually rely on a single phylogenetic tree to study evolutionary processes that affect macroecological patterns. This approach ignores the fact that each phylogenetic tree is a hypothesis about the evolutionary history of a clade, and cannot be directly observed in nature. Also, trees often leave out many extant species, or include missing species as polytomies because of a lack of information on the relationship among taxa. Still, researchers usually do not quantify...
