Data from: Why are flowers sweeter than fruits or buds? Variation in extrafloral nectar secretion throughout the floral ontogeny of a myrmecophileNora Villamil
Extrafloral nectar provision during floral ontogeny in ant-plants has not been widely studied. Extrafloral nectar secretion differed between leaves associated with buds, flowers, and fruits, and peaked during anthesis when pollinators were present. This ontogenetic variation may result from mixed selective pressures involving strategies for defense and mutualist management.
Data from: Towards smarter harvesting from natural palm populations by sparing the individuals that contribute most to population growth or productivityMerel Jansen, Niels P.R. Anten, Frans Bongers, Miguel Martínez-Ramos, Pieter A. Zuidema & Niels P. R. Anten
1. Natural populations deliver a wide range of products that provide income for millions of people and need to be exploited sustainably. Large heterogeneity in individual performance within these exploited populations has the potential to improve population recovery after exploitation and thus help sustaining yields over time. 2. We explored the potential of using individual heterogeneity to design smarter harvest schemes, by sparing individuals that contribute most to future productivity and population growth, using the...
Initial offspring size is a fundamental component of absolute growth rate, where large offspring will reach a given adult body size faster than smaller offspring. Yet, our knowledge regarding the co-evolution between offspring and adult size is limited. In time-constrained environments, organisms need to reproduce at a high rate and reach a reproductive size quickly. In order to rapidly attain a large adult body size, we hypothesize that, in seasonal habitats, large species are bound...
Data from: Complex phylogeographic patterns indicate Central American origin of two widespread Mesoamerican Quercus (Fagaceae) speciesHernando Rodríguez-Correa, Ken Oyama, Mauricio Quesada, Eric J. Fuchs, Maura Quezada, Lilian Ferrufino, Susana Valencia-Ávalos, Alfredo Cascante-Marín & Antonio González-Rodríguez
The northern Neotropical region is characterized by a heterogeneous geological and climatic history. Recent studies have shown contrasting patterns regarding the role of geographic elements as barriers that could have determined phylogeographic structure in various species. Recently, the phylogeography and biogeography of Quercus species have been studied intensively, and the patterns observed so far suggest contrasting evolutionary histories for Neotropical species in comparison with their Holarctic relatives. The goal of this study was to describe...
Data from: Reorganization of interaction networks modulates the persistence of species in late successional stagesSerguei Saavedra, Simone Cenci, Ek Del-Val, Karina Boege & Rudolf P. Rohr
1.Ecological interaction networks constantly reorganize as interspecific interactions change across successional stages and environmental gradients. This reorganization can also be associated with the extent to which species change their preference for types of niches available in their local sites. Despite the pervasiveness of these interaction changes, previous studies have revealed that network reorganizations have a minimal or insignificant effect on global descriptors of network architecture, such as: connectance, modularity, and nestedness. However, little is known...
Data from: Extensive gene tree discordance and hemiplasy shaped the genomes of North American columnar cactiDario Copetti, Alberto Burquez, Enriquena Bustamante, Joseph L. M. Charboneau, Kevin L. Childs, Luis E. Eguiarte, Seunghee Lee, Tiffany L. Liu, Michelle M. McMahon, Noah K. Whiteman, Rod A. Wing, Martin F. Wojciechowski & Michael J. Sanderson
Few clades of plants have proven as difficult to classify as cacti. One explanation may be an unusually high level of convergent and parallel evolution (homoplasy). To evaluate support for this phylogenetic hypothesis at the molecular level, we sequenced the genomes of four cacti in the especially problematic tribe Pachycereeae, which contains most of the large columnar cacti of Mexico and adjacent areas, including the iconic saguaro cactus (Carnegiea gigantea) of the Sonoran Desert. We...
Data from: Domestication genomics of the open-pollinated scarlet runner bean (Phaseolus coccineus L.)Azalea Guerra-García, Marco Suárez-Atilano, Alicia Mastretta-Yanes, Alfonso Delgado-Salinas & Daniel Piñero
The runner bean is a legume species from Mesoamerica closely related to common bean (Phaseolus vulgaris). It is a perennial species, but it is usually cultivated in small-scale agriculture as an annual crop for its dry seeds and edible immature pods. Unlike the common bean, P. coccineus has received little attention from a genetic standpoint. In this work we aim to (1) provide information about the domestication history and domestication events of P. coccineus; (2)...
Data from: Phylogenetic evidence from freshwater crayfishes that cave adaptation is not an evolutionary dead-endDavid Ben Stern, Jesse Breinholt, Carlos Pedraza-Lara, Marilú López-Mejía, Christopher L. Owen, Heather Bracken-Grissom, , Keith A. Crandall & James W. Fetzner
Caves are perceived as isolated, extreme habitats with a set of uniquely specialized biota, which long ago led to the idea that caves are ‘evolutionary dead-ends.’ This suggests that cave-adapted taxa may be doomed for extinction before they can diversify or transition to a more stable state. However, this hypothesis has not been explicitly tested in a phylogenetic framework with multiple independent cave-dwelling groups. Here we use the freshwater crayfish, a group with dozens of...
Data from: Ontogenetic changes in the phenotypic integration and modularity of leaf functional traitsXóchitl Damián, Juan Fornoni, César A. Domínguez & Karina Boege
1.Changes in resource availability, functional demands, hormonal regulation and developmental constraints can promote differences in the expression of leaf traits during plant development and foster changes in the targets of natural selection. As a consequence, the pattern and magnitude of covariation among traits, and therefore their phenotypic integration and modularity are equally expected to change throughout ontogeny. However, these changes have not been described yet. 2.We measured leaf economic, defensive and morphological traits in plants...
Data from: Sympatric parallel diversification of major oak clades in the Americas and the origins of Mexican species diversityAndrew L. Hipp, Paul S. Manos, Antonio Gonzalez-Rodriguez, Marlene Hahn, Matthew Kaproth, John D. McVay, Susana Valencia Avalos & Jeannine Cavender-Bares
Oaks (Quercus, Fagaceae) are the dominant tree genus of North America in species number and biomass, and Mexico is a global center of oak diversity. Understanding the origins of oak diversity is key to understanding biodiversity of northern temperate forests. A phylogenetic study of biogeography, niche evolution and diversification patterns in Quercus was performed using 300 samples, 146 species. Next-generation sequencing data were generated using the restriction-site associated DNA (RAD-seq) method. A time-calibrated maximum likelihood...
Data from: Shoot growth of woody trees and shrubs is predicted by maximum plant height and associated traitsSean M. Gleason, Andrea E.A. Stephens, Wade C. Tozer, Chris J. Blackman, Don W. Butler, Yvonne Chang, Alicia M. Cook, Julia Cooke, Claire A. Laws, Julieta A. Rosell, Stephanie A. Stuart, Mark Westoby & Andrea E. A. Stephens
1. The rate of elongation and thickening of individual branches (shoots) varies across plant species. This variation is important for the outcome of competition and other plant-plant interactions. Here we compared rates of shoot growth across 44 species from tropical, warm temperate, and cool temperate forests of eastern Australia. 2. Shoot growth rate was found to correlate with a suite of traits including the potential height of the species, xylem-specific conductivity, leaf size, leaf area...
1.Secondary forests are increasingly dominant in human-modified tropical landscapes, but the drivers of forest recovery remain poorly understood. Soil conditions influence plant community composition, and are expected to change over a gradient of succession. However, the role of soil conditions as an environmental filter driving community assembly during forest succession has rarely been explicitly assessed. 2.We evaluated the role of stand basal area and soil conditions on community assembly and its consequences for community functional...
Data from: Predator discrimination in the hermit crab Calcinus californiensis: tight for shell breakers, loose for shell peelersGuillermina Alcaraz & Elsah Arce
Prey exposed to predators with different hunting and feeding modes are under different selective pressures, therefore it is expected that they should exhibit plastic and adaptive antipredator responses according to current risks. The hermit crab Calcinus californiensis faces two contrasting predators, the shell peeler Arenaeus mexicanus that hunts by active searching and the shell breaker Eriphia squamata that hunts by ambush. In order to discover whether C. californiensis displays plastic responses depending on the type...
