Data from: A metacalibrated time-tree documents the early rise of flowering plant phylogenetic diversity

Susana Magallón, Sandra Gómez-Acevedo, Luna L. Sánchez-Reyes & Tania Hernández-Hernández
The establishment of modern terrestrial life is indissociable from angiosperm evolution. While available molecular clock estimates of angiosperm age range from the Paleozoic to the Late Cretaceous, the fossil record is consistent with angiosperm diversification in the Early Cretaceous. The time-frame of angiosperm evolution is here estimated using a sample representing 87% of families and sequences of five plastid and nuclear markers, implementing penalized likelihood and Bayesian relaxed clocks. A literature-based review of the palaeontological...

Data from: The evolution of signal-reward correlations in bee and hummingbird-pollinated species of Salvia

Santiago Benitez-Vieyra, Juan Fornoni, Jessica Pérez Alquicira, Karina Boege, César Augusto Domínguez, C. A. Dominguez & J. Perez-Alquicira
Within-individual variation in floral advertising and reward traits is a feature experienced by pollinators that visit different flowers of the same plant. Pollinators can use advertising traits to gather information about the quality and amount of rewards, leading to the evolution of signal–reward correlations. As long as plants differ in the reliability of their signals and pollinators base their foraging decisions on this information, natural selection should act on within-individual correlations between signals and rewards....

Data from: There is no such thing as a free cigarette: lining nests with discarded butts brings short-term benefits, but causes toxic damage

Monserrat Suárez-Rodríguez & Constantino Macías Garcia
Adaptation to human-modified environments such as cities is poised to be a major component of natural history in the foreseeable future. Birds have been shown to adapt their vocalizations, use of nesting places and activity rhythms to the urban environments, and we have previously reported that some species, including the house finch (Carpodacus mexicanus), use cellulose from smoked cigarette butts as lining material and thus reduce the number of ectoparasites in their nests, probably because...

Data from: Do freshwater ecoregions and continental shelf width predict patterns of historical gene flow in the freshwater fish Poecilia butleri?

J. Jaime Zúñiga-Vega, Spencer J. Ingley, Peter J. Unmack & Jerald B. Johnson
We examined historical patterns of gene flow in the freshwater fish Poecilia butleri in western Mexico. We tested the hypothesis that the boundaries between four freshwater ecological communities (ecoregions) might have limited the movement of P. butleri because changes in species compositions might restrict establishment between adjacent ecoregions, even in situations where a physical barrier is absent. Hence, we predicted that boundaries between ecoregions should correspond to phylogeographical breaks in P. butleri. We also tested...

Data from: Molecular proxies for climate maladaptation in a long-lived tree (Pinus pinaster Aiton, Pinaceae)

Juan Pablo Jaramilo-Correa, Isabel Rodríguez-Quilón, Delphine Grivet, Camille Lepoittevin, Federico Sebastiani, Myriam Heuertz, Pauline H. Garnier-Géré, Ricardo Alía, Christophe Plomion, Giovanni G. Vendramin, Santiago C. González-Martínez, J.-P. Jaramillo-Correa, S. C. Gonzalez-Martinez & P. H. Garnier-Gere
Understanding adaptive genetic responses to climate change is a main challenge for preserving biological diversity. Successful predictive models for climate-driven range shifts of species depend on the integration of information on adaptation, including that derived from genomic studies. Long-lived forest trees can experience substantial environmental change across generations, which results in a much more prominent adaptation lag than in annual species. Here, we show that candidate-gene SNPs (Single Nucleotide Polymorphisms) can be used as predictors...

Data from: A new species of horned lizard (genus Phrynosoma) from Guerrero, México, with an updated multilocus phylogeny

Adrián Nieto-Montes De Oca, Diego Arenas-Moreno, Elizabeth Beltrán-Sánchez & Adam D. Leaché
We describe a new species of Phrynosoma from central northeastern Guerrero, México; perform a phylogenetic analysis of mitochondrial and nuclear sequence data to estimate its phylogenetic relationships; and investigate the monophyly of Phrynosoma asio, P. braconnieri, and P. taurus. The new species can be distinguished from all of its congeners by the possession of a unique combination of morphological characteristics. The molecular genetic data include three fragments of the mitochondrial genome and six nuclear genes...

Data from: Enhanced male coloration after immune challenge increases reproductive potential

Alberto Velando, Rene Beamonte-Barrientos & Roxana Torres
In many animal species, females select a mate on the basis of the expression of secondary sexual traits. A prevalent theory suggests that male ornaments are reliable indicators of immunocompetence, because the cost of immune function prevents cheating. However, sexual signalling is a component of males’ reproductive effort, and an immune challenge may also alter the organism’s perceived future prospects and hence their signalling effort. In this study, to investigate the consequences of mounting an...

Data from: The role of mitochondrial introgression in illuminating the evolutionary history of Nearctic treefrogs

, Brian Tilston Smith, Adrian Nieto-Montes De Oca, Uri Omar Garcia-Vazquez, Brett R. Riddle & Robert W. Bryson
Inferring the evolutionary history of lineages often becomes difficult when gene histories are in conflict with each other. Introgression, for example, can cause DNA sequences from one species to be more similar to sequences of a different species and lead to incongruence amongst gene trees. However, incorporating congruent and incongruent locus-specific phylogenetic estimates with the geographical distribution of lineages may provide valuable insight into evolutionary processes important to speciation. In this study, we investigated mitochondrial...

Data from: Sustainable harvesting of non-timber forest products based on ecological and economic criteria

Juan C. Hernández-Barrios, Niels P. R. Anten & Miguel Martínez-Ramos
Harvesting of highly valuable non-timber forest products (NTFPs) has been considered a win-win strategy where local people profit while conserving forest biodiversity and ecosystem services. Nevertheless the sustainability of NTFP harvesting has been debated as the nature of NTFPs, harvesting regimes, and scale of commercialization are highly heterogeneous and few studies have evaluated the cumulative ecological and economic effects of such regimes. Here, we assessed the medium-term (10 years) sustainability of NTFP harvesting, using Chameadorea...

Data from: Experimental defaunation of terrestrial mammalian herbivores alters tropical rain forest understory diversity

Angela A. Camargo-Sanabria, Eduardo Mendoza, Roger Guevara, Miguel Martínez-Ramos & Rodolfo Dirzo
It has been suggested that tropical defaunation may unleash community-wide cascading effects, leading to reductions in plant diversity. However, experimental evidence establishing cause–effect relationships thereof is poor. Through a 5 year exclosure experiment, we tested the hypothesis that mammalian defaunation affects tree seedling/sapling community dynamics leading to reductions in understorey plant diversity. We established plot triplets (n = 25) representing three defaunation contexts: terrestrial-mammal exclosure (TE), medium/large mammal exclosure (PE) and open access controls (C)....

Data from: RAD sequencing, genotyping error estimation and de novo assembly optimization for population genetic inference

Alicia Mastretta-Yanes, Nils Arrigo, Nadir Alvarez, Tove H. Jorgensen, Daniel Piñero & Brent C. Emerson
Restriction site-associated DNA sequencing (RADseq) provides researchers with the ability to record genetic polymorphism across thousands of loci for non-model organisms, potentially revolutionising the field of molecular ecology. However, as with other genotyping methods, RADseq is prone to a number of sources of error that may have consequential effects for population genetic inferences, and these have received only limited attention in terms of the estimation and reporting of genotyping error rates. Here we use individual...

Data from: Do the historical biogeography and evolutionary history of the digenean Margotrema spp. across central Mexico mirror those of their freshwater fish hosts (Goodeinae)?

Andrés Martínez-Aquino, Fadia Sara Ceccarelli, Luis E. Eguiarte, Ella Vázquez-Domínguez & Gerardo Pérez-Ponce De León
Host-parasite systems provide an ideal platform to study evolution at different levels, including codivergence in a historical biogeography context. In this study we aim to describe biogeographic and codivergent patterns and associated processes of the Goodeinae freshwater fish and their digenean parasite (Margotrema spp.) over the last 6.5 Ma (million years), identifying the main factors (host and/or hydrogeomorphology) that influenced the evolution of Margotrema. We obtained a species tree for Margotrema spp. using DNA sequence...

Data from: Community assembly and functional diversity along succession post-management

Radika Bhaskar, Todd E. Dawson & Patricia Balvanera
1. Despite extensive development of successional theory, few empirical studies have evaluated whether existing models are applicable to human-modified landscapes. Seasonally dry tropical forests are experiencing widespread transformation, and represent a critical system to assess in a successional framework to infer the mechanisms that shape assembly of secondary forests post-management. 2. We used a functional trait-based approach to assess changes in community assembly mechanisms along succession in secondary dry forests of varying stages following abandonment...

Data from: Abortion legislation, maternal healthcare, fertility, female literacy, sanitation, violence against women, and maternal deaths: a natural experiment in 32 Mexican states

Elard Koch, Monique Chireau, Fernando Pliego, Joseph Stanford, Sebastián Haddad, Byron Calhoun, Paula Aracena, Miguel Bravo, Sebastián Gatica & John Thorp
Objective: To test whether there is an association between abortion legislation and maternal mortality outcomes after controlling for other factors thought to influence maternal health. Design: Population-based natural experiment. Setting and data sources: Official maternal mortality data from 32 federal states of Mexico between 2002 and 2011. Main outcomes: Maternal mortality ratio (MMR), MMR with any abortive outcome (MMRAO) and induced abortion mortality ratio (iAMR). Independent variables: Abortion legislation grouped as less (n=18) or more...

Data from: Genetic diversity and population history of the endangered killifish Aphanius baeticus

Elena G. Gonzalez, Carlos Pedraza-Lara & Ignacio Doadrio
The secondary freshwater fish fauna of the western-Iberian Peninsula basin is primarily restricted to local coastal streams, and man-made salt evaporation ponds, etc., which are susceptible to periodical flood and drought events. Despite its uniqueness in ecological adaptation to high saltwater tolerance, very little is known about this fauna’s population dynamics and evolutionary history. The killifish, Aphanius baeticus (Cyprinodontidae) is an endemic species restricted to river basins on Spain’s southern Atlantic coastline, considered as “Endangered.”...

Data from: Better stay together: pair bond duration increases individual fitness independent of age-related variation

Oscar Sánchez-Macouzet, Cristina Rodríguez & Hugh Drummond
Prolonged pair bonds have the potential to improve reproductive performance of socially monogamous animals by increasing pair familiarity and enhancing coordination and cooperation between pair members. However, this has proved very difficult to test robustly because of important confounds such as age and reproductive experience. Here, we address limitations of previous studies and provide a rigorous test of the mate familiarity effect in the socially monogamous blue-footed booby, Sula nebouxii, a long-lived marine bird with...
