Data and code from: Amphibian speciation rates support a general role of mountains as biodiversity pumps

Adrián García-Rodríguez
Continental mountain areas cover less than 15% of global land surface, yet, these regions concentrate over 80% of global terrestrial diversity. One prominent hypothesis to explain this pattern proposes that high mountain diversities could be explained by higher diversification rates in regions of high topographic complexity. While high speciation in mountains has been detected for particular clades and regions, the global extent to which lineages experience faster speciation in mountains remains unknown. Here we address...

Phenotypic and genomic diversification with isolation by environment along elevational gradients in a neotropical treefrog

Ricardo Medina, Ella Vázquez-Domínguez, Guinevere O.U. Wogan, Ke Bi, Flavia Termignoni-García, Manuel Hernando Bernal, Juan P. Jaramillo-Correa & Ian J. Wang
Understanding how geographic and environmental heterogeneity drive local patterns of genetic variation is a major goal of ecological genomics and a key question in evolutionary biology. The tropical Andes and inter-Andean valleys are shaped by markedly heterogeneous landscapes, where species experience strong selective processes. We examined genome-wide SNP data together with behavioral and ecological traits (mating calls and body size) known to contribute to genetic isolation in anurans in the emerald-eyed treefrog, Boana platanera, distributed...

Data from: National assessments of species vulnerability to climate change strongly depend on selected data sources

Daniel Scherrer, Manuel Esperon-Rodriguez, Linda J. Beaumont, Victor L. Barradas & Antoine Guisan
Aim: Correlative species distribution models (SDMs) are among the most frequently used tools for conservation planning under climate and land-use changes. Conservation-focused climate change studies are often conducted on a national or local level and can use different sources of occurrence records (e.g., local databases, national biodiversity monitoring) collated at different geographic extents. However, little is known about how these restrictions in geographic space (i.e., Wallacean shortfall) can lead to restrictions in environmental space (i.e....

Data from: A new Cenomanian acanthomorph fish from the El Chango quarry (Chiapas, South-Eastern Mexico) and its implications for the early diversification and evolutionary trends of acanthopterygians

Kleyton Magno Cantalice, Bruno Andrés Than-Marchese & Eduardo Villalobos-Segura
A new Cenomanian spiny-rayed fish from El Chango quarry, Chiapas, South Eastern Mexico is described and included, together with Zoqueichthys carolinae and Pepemkay maya, in the most recent phylogenetic analysis of acanthomorph fishes encompassing both extant and extinct taxa. The topologies recovered from the parsimony phylogenetic analysis using both multistate, or composite, and contingent, or reductive, coding are compared against each other and with a Bayesian estimation. All the analyses corroborate the placement of Z....

Phylogenomic and ecological analyses reveal the spatiotemporal evolution of global pines

Wei-Tao Jin, David Gernandt, Christian Wehenkel, Xiao-Mei Xia, Xiao-Xin Wei & Xiao-Quan Wang
How coniferous forests evolved in the Northern Hemisphere remains largely unknown. Unlike most groups of organisms that generally follow a latitudinal diversity gradient, most conifer species in the Northern Hemisphere are distributed in mountainous areas at middle latitudes. It is of great interest to know whether the mid-latitude region has been an evolutionary cradle or museum for conifers and how evolutionary and ecological factors have driven their spatiotemporal evolution. Here, we investigated the macroevolution of...

Data from: Dung beetle activity had no positive effect on nutrient concentration or performance of established rainforest seedlings

Lina Adonay Urrea-Galeano, Ellen Andresen, Rosamond Coates, Francisco Mora Ardila, Ek Del-Val & Maribel Nava Mendoza
All five datasets from this study correspond to field observations collected for seedlings of six tree species (Brosimum alicastrum, Calophyllum brasiliense, Cymbopetalum baillonii, Diospyros digyna, Omphalea oleifera and Poulsenia armata) in a tropical rainforest (Los Tuxtlas, Mexico). We estimated the concentrations of foliar nitrogen (N) and phosphorus (P), resource allocation (the ratio of biomass allocated to shoot vs root), seedling survival, and growth. Experimental seedlings were subject to three treatment levels: (a) feces added and...

Environmental heterogeneity shapes physiological traits in tropical direct-developing frogs

Ruth Percino-Daniel, José M Contreras López, Oswaldo Telléz-Valdés, Fausto R Mendéz De La Cruz, Alejandro Gonzalez-Voyer & Daniel Piñero
1. Tropical ectotherm species tend to have narrower physiological limits than species from temperate areas. As a consequence, tropical species are considered highly vulnerable to climate change since minor temperature increases can push them beyond their physiological thermal tolerance. Differences in physiological tolerances can also be seen at finer evolutionary scales, such as among populations of ectotherm species along elevation gradients, highlighting the physiological sensitivity of such organisms. 2. Here we analyze the influence of...

Selection for phage resistance reduces virulence of Shigella flexneri

Kaitlyn Kortright, Rachel Done, Benjamin Chan, Valeria Souza & Paul Turner
There is increasing interest in phage therapy as an alternative to chemical antibiotics for treating bacterial infections, especially using phages that select for evolutionary trade-offs between increased phage resistance and decreased fitness traits such as virulence in target bacteria. A vast repertoire of virulence factors allows the opportunistic bacterial pathogen, Shigella flexneri, to invade human gut epithelial cells, to replicate intracellularly, and to evade host immunity through intercellular spread; the latter is an infection stage...

Data from: Tree recruitment failure in old-growth forest patches across human-modified rainforests

Ricard Arasa-Gisbert, Víctor Arroyo-Rodríguez, Carmen Galán-Acedo, Jorge A. Meave & Miguel Martínez-Ramos
1. Land-use change threatens biodiversity in tropical landscapes, but its impact on forest regeneration remains poorly known. In fact, the landscape-scale patterns driving the diversity of regenerating plants within forest fragments have been rarely explored, and we are uncertain whether such drivers vary across regions with different land-use change patterns. 2. We assessed the effect of landscape composition (forest cover and matrix openness) and configuration (forest patch density) on species diversity of sapling assemblages (trees...

Etnoarqueología para el combate a la pobreza: la estrategia ignorada por el estado Mexicano

Sandra L. López Varela
pp. 195-211 Alexander von Humboldt (1988 [1811]) describes in his Essai Politique sur le Royaume de la Nouvelle Espagne, the landscape of social inequality that existed in New Spain in terms of the distribution of wealth, civilization and soil cultivation during the reign of Charles IV. For more than two centuries, the Mexican government has tried unsuccessfully to revert social end economic inequality through economic growth and development policies. In the following pages, I discuss...

Good alimentation can overcome the negative effects of climate change on growth in reptiles

Pilar Rueda-Zozaya, Melissa Plasman & Victor Hugo Reynoso
Climate change may lead to higher nest temperatures, which may increase embryo development rate, but reduce hatchling size and growth. Larger body size permits better performance, making growth an important fitness trait. In ectotherms, growth is affected by temperature and food quality. To segregate the effects of incubation temperature vs. alimentation on the growth of the Mexican black spiny tailed iguana Ctenosaura pectinata, we incubated eggs at 29 and 32ºC, and hatchlings were kept at...

Data from: Low-copy nuclear genes reveal new evidence of incongruence in relationships within Malvaceae s.l.

Rebeca Hernández-Gutiérrez, Carolina Granados Mendoza & Susana Magallón
The family Malvaceae s. l. is a clade that comprises nine subfamilies. Phylogenetic relationships among them are not completely resolved and are inconsistent among studies, probably due to low phylogenetic informativeness of conventional molecular markers. In the present study, we provide new phylogenetic information for Malvaceae s.l. derived from newly-designed group-specific nuclear markers. By mining transcriptome data from the One Thousand Plant Project (1KP) and publicly available genome information from cotton, cacao, and Arabidopsis, we...

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress

Viridiana Avila-Magaña, Bishoy Kamel, Michael DeSalvo, Kelly Gómez-Campo, Susana Enríquez, Hiroaki Kitano, Rori Rohlfs, Roberto Iglesias-Prieto & Mónica Medina
As coral reefs struggle to survive under climate change, it is crucial to know whether they have the capacity to withstand changing conditions, particularly increasing seawater temperatures. Thermal tolerance requires the integrative response of the different components of the coral holobiont (coral host, algal photosymbiont, and associated microbiome). Here, using a controlled thermal stress experiment across three divergent Caribbean coral species, we attempt to dissect holobiont member metatranscriptome responses from coral taxa with different sensitivities...

Volcanism and paleoclimate change drive diversification of world’s largest whip spider (Amblypygi)

Frederic Dominique Schramm, Alejandro Valdez-Mondragón & Lorenzo Prendini
The tropics contain many of the most biodiverse regions on Earth but the processes responsible for generating this diversity remain poorly understood. This study investigated the drivers of diversification in arthropods with stenotopic ecological requirements and limited dispersal capability using as model the monotypic whip spider (Amblypygi) genus Acanthophrynus, widespread in the tropical deciduous forests of Mexico. We hypothesized that for these organisms, the tropical deciduous forests serve as a conduit for dispersal, with their...

Cumulative germination of seeds ingested by black howler monkeys

Julieta Benitez Malvido & Ana Maria González-Di Pierro
Premise of the Study: Primates are important seed dispersers, especially for large-seeded (> 1 cm length) tropical species in continuous and fragmented rainforests. Methods: In three forest fragments within the Montes Azules Biosphere Reserve, southern Mexico, we investigated the effect of howler monkeys´ (Alouatta pigra) gut passage on the germination rate and maximum germination (%) of native large-seeded species. One group of howler monkeys, per fragment, was followed and fresh feces collected. Large seeds were...

Data for: Using spatial patterns of seeds and saplings to assess the prevalence of heterospecific replacements among cloud forest canopy tree species

Nancy R. Mejía-Domínguez, Jorge A. Meave, Carlos Díaz-Ávalos & Lorena Gómez-Aparicio
Questions: To gain insights into the role of species-by-species replacements in cloud forest community structuring, we asked: (1) What are the effects of the spatial distribution of standing individuals on the seed rain, soil seed bank, and sapling density and survival in this cloud forest? and (2) What is the prevalence of conspecific vs. heterospecific replacements in the regeneration of this forest? Location: Santo Tomás Teipan, Oaxaca State, southern Mexico. Methods: In a 1-ha cloud...

Data from: Molecular and morphological evidence reveals a new species of Antiphytum (Echiochiloideae, Boraginaceae) from Guerrero, Mexico

Nidia Mendoza-Díaz, Helga Ochoterena, Michael J. Moore & Hilda Flores-Olvera
Molecular and morphological evidence supports a new species in the genus Antiphytum from the Sierra Madre del Sur, in the state of Guerrero, Mexico, here described as A. brevicalyx. This species is unique in the genus by possessing a calyx shorter than the corolla tube at anthesis; it is similar to A. floribundum in inflorescence arrangement, but differs from that species in lacking a basal leaf rosette and having appendages on the corolla throat. According...

The relative effects of pace of life and habitat characteristics on the evolution of sexual ornaments: a comparative assessment

Will Sowersby, Simon Eckerström-Liedholm, Piotr Rowiński, Julia Balogh, Stefan Eiler, Joseph Upstone, Alejandro Gonzalez-Voyer & Björn Rogell
Selection may favor greater investment into sexual ornaments when opportunities for future reproduction are limited (e.g., due to high adult mortality). However, a key driver of mortality, predation, typically selects against elaborate sexual ornaments. Here, we examine the evolution of sexual ornaments in a group of killifishes, which have marked contrasts in life-history strategy between species and inhabit environments that differ in their accessibility to aquatic predators. We first assessed if the size of sexual...

Colorful traits in female birds relate to individual condition, reproductive performance, and male mate preferences: A meta-analytic approach dataset

America Hernandez, Rene Beamonte-Barrientos, Margarita Martinez-Gomez & Bibiana Montoya
Colorful traits in females are suggested to have evolved and be maintained by sexual selection. Although several studies have evaluated this idea, support is still equivocal. Evidence has been compiled in reviews, and a handful of quantitative synthesis have explored evidence of the link between condition and specific color traits in males and females. However, understanding the potential function of females’ colorful traits in sexual communication has not been the primary focus of any of...

Non-adaptive evolutionary processes governed the diversification of a temperate conifer lineage after its migration into the tropics

Jorge Cruz Nicolás, Alfredo Villarruel-Arroyo, David S. Gernandt, Rosa M. Fonseca, Erika Aguirre-Planter, Luis E. Eguiarte & Juan Pablo Jaramillo-Correa
Constructing phylogenetic relationships among closely related species is a recurrent challenge in evolutionary biology, particularly for long-lived taxa with large effective population sizes and uncomplete reproductive isolation, like conifers. Conifers further have slow evolutionary rates, which raises the question of whether adaptive or non/adaptive processes were predominantly involved when they rapidly diversified after migrating from temperate regions into the tropical mountains. Indeed, fine-scale phylogenetic relationships within several conifer genus remain under debate. Here, we studied...

The details regarding data processing are provided...

Saguaro recruitment data obtained by inverse-growth modelling

Eugenio Larios, Ricardo Efren Felix-Burruel, Edgar J. Gonzalez & Alberto Burquez
Each year, an individual mature large saguaro cactus produces about one million seeds in attractive juicy fruits that lure seed predators and seed dispersers in a three-month feast. From the million seeds produced, however, only a few will persist into mature saguaros. A century of research on saguaro population dynamics has led to the conclusion that saguaro recruitment is an episodic event that depends on the convergence of suitable conditions for survival during the critical...

Data from manuscript: Assessment of the 7075-T6-aluminum-alloy/microalloyed-dual-phase-steel joint for automotive chassis

Rodrigo Mayen-Mondragon, Juan Genesca-Llongueras & Vianey Torres-Mendoza
The corrosion behavior of a 7075-T6 Aluminum Alloy sample (AA7075-T6) and a low-Carbon low-Manganese microalloyed dual-phase steel sample (MADPS) were studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP). The galvanic corrosion resulting from their assembly within a dissimilar joint, was studied by the zero-resistance ammeter technique (ZRA). The tests were conducted at room temperature and pressure (Mexico City) using an aqueous solution of 3% NaCl as electrolyte (pH 5.3) and without deaereating the...
