Indrikis Krams, Sanita Kecko, Priit Jõers, Giedrius Trakimas, Didzis Elferts, Ronalds Krams, Severi Luoto, Markus J. Rantala, Inna Inashkina, Dita Gudrā, Dāvids Fridmanis, Jorge Contreras-Garduño, Lelde Grantiņa-Ieviņa & Tatjana Krama
Communities of symbiotic microorganisms that colonize the gastrointestinal tract play an important role in food digestion and protection against opportunistic microbes. Diet diversity increases the number of symbionts in the intestines, a benefit that is considered to impose no cost for the host organism. However, less is known about the possible immunological investments that hosts have to make in order to control the infections caused by symbiont populations that increase due to diet diversity. By...

Data from: An experimental demonstration that house finches add cigarette butts in response to ectoparasites

Monserrat Suárez-Rodríguez & Constantino Macías Garcia
Urban species encounter resources that are uncommon in nature, such as materials found in city waste. Many studies have shown that these can be harmful to wildlife. In Mexico City, house finches bring cigarette butts to their nests, which reduces the amount of ectoparasites, but also induces genotoxic damage in chicks and parents. Yet, the reason for this behaviour is unknown. One possibility is that birds extract the cellulose fibres from discarded butts simply because...

Data from: Morphological convergence in a Mexican garter snake associated with the ingestion of a novel prey

Javier Manjarrez, Constantino Macías Garcia & Hugh Drummond
Morphological convergence is expected when organisms which differ in phenotype experience similar functional demands, which lead to similar associations between resource utilization and performance. To consume prey with hard exoskeletons, snakes require either specialized head morphology, or to deal with them when they are vulnerable, e.g. during molting. Such attributes may in turn reduce the efficiency with which they prey on soft-bodied, slippery animals such as fish. Snakes which consume a range of prey may...

Data from: Towards smarter harvesting from natural palm populations by sparing the individuals that contribute most to population growth or productivity

Merel 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...

Data from: High fidelity: extra-pair fertilisations in eight Charadrius plover species are not associated with parental relatedness or social mating system

Kathryn H. Maher, Luke J. Eberhart-Phillips, András Kosztolányi, Natalie Dos Remedios, María Cristina Carmona-Isunza, Medardo Cruz-López, Sama Zefania, James J. H. St Clair, Monif AlRashidi, Michael A. Weston, Martín A. Serrano-Meneses, Oliver Krüger, Joseph I. Hoffmann, Tamás Székely, Terry Burke, Clemens Küpper & Joseph I. Hoffman
Extra-pair paternity is a common reproductive strategy in many bird species. However, it remains unclear why extra-pair paternity occurs and why it varies among species and populations. Plovers (Charadrius spp.) exhibit considerable variation in reproductive behaviour and ecology, making them excellent models to investigate the evolution of social and genetic mating systems. We investigated inter- and intra-specific patterns of extra-pair parentage and evaluated three major hypotheses explaining extra-pair paternity using a comparative approach based on...

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: Reorganization of interaction networks modulates the persistence of species in late successional stages

Serguei 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: Soil-mediated filtering organizes tree assemblages in regenerating tropical forests

Bruno Ximenes Pinho, Felipe Pimentel Lopes De Melo, Víctor Arroyo-Rodríguez, Simon Pierce, Madelon Lohbeck & Marcelo Tabarelli
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: Complex phylogeographic patterns indicate Central American origin of two widespread Mesoamerican Quercus (Fagaceae) species

Hernando 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: Why are flowers sweeter than fruits or buds? Variation in extrafloral nectar secretion throughout the floral ontogeny of a myrmecophile

Nora 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: Phylogenetic evidence from freshwater crayfishes that cave adaptation is not an evolutionary dead-end

David 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: Sympatric parallel diversification of major oak clades in the Americas and the origins of Mexican species diversity

Andrew 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: Predator discrimination in the hermit crab Calcinus californiensis: tight for shell breakers, loose for shell peelers

Guillermina 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...

Data from: Ontogenetic changes in the phenotypic integration and modularity of leaf functional traits

Xóchitl 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: Time-limited environments affect the evolution of egg - body size allometry

Simon Eckerström-Liedholm, Will Sowersby, Alejandro Gonzalez-Voyer & Björn Rogell
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: Shoot growth of woody trees and shrubs is predicted by maximum plant height and associated traits

Sean 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...

Data from: Extensive gene tree discordance and hemiplasy shaped the genomes of North American columnar cacti

Dario 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: Finding a needle in a haystack: distinguishing Mexican maize landraces using a small number of SNPs

Jose Luis Caldu-Primo, Alicia Mastretta-Yanes, Ana Wegier & Daniel Piñero
In Mexico's territory, the center of origin and domestication of maize (Zea mays), there is a large phenotypic diversity of this crop. This diversity has been classified into “landraces.” Previous studies have reported that genomic variation in Mexican maize is better explained by environmental factors, particularly those related with altitude, than by landrace. Still, landraces are extensively used by agronomists, who recognize them as stable and discriminatory categories for the classification of samples. In order...

Data from: Canopy height variation and environmental heterogeneity in the tropical dry forests of coastal Oaxaca, Mexico

Silvia H. Salas-Morales, Edgar J. González, J.A. Meave & Jorge A. Meave
Despite its importance for carbon storage and other ecosystem functions, the variation of vegetation canopy height is not yet well understood. We examined the relationship between this community attribute and environmental heterogeneity in a tropical dry forest of southern Mexico. We sampled vegetation in 15 sites along a 100-km coastal stretch of Oaxaca State, and measured the heights of all woody plants (excluding lianas). The majority of the ca. 4000 individuals recorded concentrated in the...

Data from: Commonness, rarity and oligarchies of woody plants in the tropical dry forests of Mexico

John N. Williams, Irma Trejo & Mark W. Schwartz
We assessed woody plant communities in two widely separated forests in the tropical dry forest (TDF) biome of Mexico for evidence of similar patterns of species commonness and rarity. We used belt transects laid out along contour lines (i.e., constant elevation) and stratified across elevation gradients at sites in Jalisco and Oaxaca to sample woody plant species diversity, abundance, relative frequency and basal area. We assembled a combined species list and compared species found in...

Data from: Herbivory facilitates growth of a key reef-building Caribbean coral

Adam Suchley & Lorenzo Alvarez-Filip
The decline of reef-building corals in conjunction with shifts to short-lived opportunistic species has prompted concerns that Caribbean reef framework-building capacity has substantially diminished. Restoring herbivore populations may be a potential driver of coral recovery; however, the impact of herbivores on coral calcification has been little studied. We performed an exclusion experiment to evaluate the impact of herbivory on Orbicella faveolata coral growth over 14 months. The experiment consisted of three treatments: full exclusion cages;...

Data from: The role of livestock intensification and landscape structure in maintaining tropical biodiversity

Fredy Alvarado, Federico Escobar, David R. Williams, Víctor Arroyo-Rodríguez & Fernando Escobar-Hernández
1. As tropical cattle ranching continues to expand, successful conservation will require an improved understanding of the relative impacts of different livestock systems and landscape structure on biodiversity. Here, we provide the first empirical and multi-scale assessment of the relative effects of livestock intensification and landscape structure on biodiversity in the threatened tropical dry forests of Mesoamerica. 2. We used a dataset of dung beetles (169 372 individuals from 33 species) collected from twenty 1-km2...

Data from: When homoplasy is not homoplasy: dissecting trait evolution by contrasting composite and reductive coding

Alejandro Torres-Montúfar, Thomas Borsch & Helga Ochoterena
The conceptualization and coding of characters is a difficult issue in phylogenetic systematics, no matter which inference method is used when reconstructing phylogenetic trees or if the characters are just mapped onto a specific tree. Complex characters are groups of features that can be divided into simpler hierarchical characters (reductive coding), although the implied hierarchical relational information may change depending on the type of coding (composite vs reductive). Up to now, there is no common...

Data from: A phylogenomic perspective on the biogeography of skinks in the Plestiodon brevirostris group inferred from target enrichment of ultraconserved elements

, Charles W. Linkem, Carlos J. Pavón-Vázquez, Adrián Nieto-Montes De Oca, John Klicka, John E. McCormack & Robert W. Bryson
Aim: The aim of our study was to reconstruct ancestral geographic distributions from time-calibrated phylogenies generated from phylogenomic data to answer three broad questions about the biogeography of skinks in the Plestiodon brevirostris group: (1) Are biogeographic patterns correlated with the formation of the Trans-Mexican Volcanic Belt? (2) Do different methods of phylogenetic estimation result in different topologies? If so, (3) are biogeographic reconstructions impacted by the use of different phylogenetic trees? Location: Mexico. Methods:...

Data from: Genomic footprints of adaptation in a cooperatively breeding tropical bird across a vegetation gradient

Flavia Termignoni-Garcia, Juan P. Jaramillo-Correa, Juan Chablé-Santos, Mark Liu, Allison J. Shultz, Scott V. Edwards, Patricia Escalante Pliego & Patricia Escalante-Pliego
Identifying the genetic basis of phenotypic variation and its relationship with the environment is key to understanding how local adaptations evolve. Such patterns are especially interesting among populations distributed across habitat gradients, where genetic structure can be driven by isolation by distance (IBD) and/or isolation by environment (IBE). Here, we used variation in ~1,600 high-quality SNPs derived from paired-end sequencing of double-digest restriction site-associated DNA (ddRAD-Seq) to test hypotheses related to IBD and IBE in...
