Data from: Estimating the temporal and spatial extent of gene flow among sympatric lizard populations (genus Sceloporus) in the southern Mexican highlands

Interspecific gene flow is pervasive throughout the tree of life. Although detecting gene flow between populations has been facilitated by new analytical approaches, determining the timing and geography of hybridization has remained difficult, particularly for historical gene flow. A geographically explicit phylogenetic approach is needed to determine the overlap of ancestral populations. In this study, we performed population genetic analyses, species delimitation, simulations and a recently developed approach of species tree diffusion to infer the...

Data from: Nectar robbing: a common phenomenon mainly determined by accessibility constraints, nectar volume and density of energy rewards

Sandra V. Rojas-Nossa, José María Sánchez & Luis Navarro
Nectar robbers use a hole made in the perianth to extract nectar. Since robbers may modify plant fitness, they play an important role by driving evolution on floral traits, shaping population structure and influencing community dynamics. Although nectar robbing is widespread in angiosperms, the causes and ecological implications of this behaviour on large ecological scales are still unexplored. Our aim is to study the frequency of nectar robbing in plants of temperate and tropical regions...

Data from: Short tree, long tree, right tree, wrong tree: new acquisition bias corrections for inferring SNP phylogenies

Adam D. Leaché, Barbara L. Banbury, Joseph Felsenstein, Adrián Nieto-Montes De Oca & Alexandros Stamatakis
Single nucleotide polymorphisms (SNPs) are useful markers for phylogenetic studies owing in part to their ubiquity throughout the genome and ease of collection. Restriction site associated DNA sequencing (RADseq) methods are becoming increasingly popular for SNP data collection, but an assessment of the best practises for using these data in phylogenetics is lacking. We use computer simulations, and new double digest RADseq (ddRADseq) data for the lizard family Phrynosomatidae, to investigate the accuracy of RAD...

Data from: Post-dispersal seed recovery by animals: is it a plant- or an animal-driven process?

Ramón Perea, Rodolfo Dirzo, Alfonso San Miguel & Luis Gil
The ability of animals to find and consume hoarded seeds (i.e. seed recovery) is a key stage within the seed dispersal process. However, the ecology of seed recovery is still poorly understood. Here, we analyze the factors controlling seed recovery by scatter-hoarding rodents in an oak-dominated temperate forest. We examined the relative importance of intrinsic seed traits (i.e. plant-driven) and extrinsic seed factors (i.e. animal-driven) on the probability of seed recovery. We found that seed...

Data from: In and out of refugia: historical patterns of diversity and demography in the North American Caesar’s mushroom species complex

Santiago Sánchez-Ramirez, Rodham E. Tulloss, Laura Guzmán-Davalos, Joaquín Cifuentes-Blanco, Ricardo Valenzuela, Arturo Estrada-Torres, Felipe Ruán-Soto, Raúl Díaz-Moreno, Nallely Hernández-Rico, Mariano Torres-Gómez, Hugo León & Jean-Marc Moncalvo
Some of the effects of past climate dynamics on plant and animal diversity make-up have been relatively well studied, but to less extent in fungi. Pleistocene refugia are thought to harbor high biological diversity (i.e. phylogenetic lineages and genetic diversity), mainly as a product of increased reproductive isolation and allele conservation. In addition, high extinction rates and genetic erosion is expected in previously glaciated regions. Some of the consequences of past climate dynamics might involve...
