Data from: Uncovering higher-taxon diversification dynamics from clade age and species-richness data

Luna L. Sánchez-Reyes, Hélène Morlon & Susana Magallon
The relationship between clade age and species richness has been increasingly used in macroevolutionary studies as evidence for ecologically versus time-dependent diversification processes. However, theory suggests that phylogenetic structure, age type (crown or stem age), and taxonomic delimitation can affect estimates of the age-richness correlation (ARC) considerably. We currently lack an integrative understanding of how these different factors affect ARCs, which in turn, obscures further interpretations. To assess its informative breadth, we characterize ARC behavior...

Data from: Multiple scaling behavior and nonlinear traits in music scores

Alfredo González-Espinoza, Hernan Larralde, Gustavo Martinez-Mekler & Markus Mueller
We present a statistical analysis of music scores from different composers using detrended fluctuation analysis. We find different fluctuation profiles that correspond to distinct auto-correlation structures of the musical pieces. Further, we reveal evidence for the presence of nonlinear auto-correlations by estimating the detrended fluctuation analysis of the magnitude series, a result validated by a corresponding study of appropriate surrogate data. The amount and the character of nonlinear correlations vary from one composer to another....

Data from: A phylogenetic, biogeographic, and taxonomic study of all extant species of Anolis (Squamata; Iguanidae)

Steven Poe, Adrian Nieto-Montes De Oca, Omar Torres-Carvajal, Kevin De Queiroz, Julian A. Velasco, Brad Truett, Levi N. Gray, Mason J. Ryan, Gunther Kohler, Fernando Ayala-Varela & Ian Latella
Anolis lizards (anoles) are textbook study organisms in evolution and ecology. Although several topics in evolutionary biology have been elucidated by the study of anoles, progress in some areas has been hampered by limited phylogenetic information on this group. Here we present a phylogenetic analysis of all 379 extant species of Anolis, with new phylogenetic data for 139 species including new DNA data for 101 species. We use the resulting estimates as a basis for...

Data from: Speciation genomics and a role for the Z chromosome in the early stages of divergence between Mexican ducks and mallards

Philip Lavretsky, Jeffrey M. DaCosta, Blanca E. Hernández-Baños, , Michael D. Sorenson, Jeffrey L. Peters & Andrew Engilis
Speciation is a continuous and dynamic process, and studying organisms during the early stages of this process can aid in identifying speciation mechanisms. The mallard (Anas platyrhynchos) and Mexican duck (A. [p.] diazi) are two recently diverged taxa with a history of hybridization and controversial taxonomy. To understand their evolutionary history, we conducted genomic scans to characterize patterns of genetic diversity and divergence across the mitochondrial DNA (mtDNA) control region, 3523 autosomal loci and 172...

Grad-Shafranov equation: MHD simulation of the new solution obtained from the Fadeev and Naval models

Arian Ojeda Gonzalez, Leandro Nunes Dos Santos, José Juan González-Avilés, Victor De La Luz & Pablo Rubén Muñoz-Gutberlet
This article aims to obtain a new analytical solution of a specific form of the Grad-Shafranov (GS) equation using Walker's formula. The new solution has magnetic field lines with X-type neutral points, magnetic islands and singular points. The singular points are located on the x-axis. The X-points and the center of the magnetic islands do not appear on the x-axis an island appears at $z>0$ and the other two at $z<0$. The aforementioned property allows...

Atmospheric and soil drought risks combined shape community assembly of trees in a Tropical Dry Forest

Moises Méndez-Toribio, Guillermo Ibarra-Manríquez, Horacio Paz & Edwin Lebrija-Trejos
1. Predicting plant community assembly is challenging in part because the influence of environmental conditions via plant functional strategies and the relevance of mechanisms of community assembly change across habitats and these changes remain poorly studied. 2. To assess how environmental conditions drive species sorting in a tropical dry forest, we used the combined RLQ and Fourth-Corner methods to analyze changes in tree species assemblages among sites with distinct atmospheric and soil drought risks. We...

Using niche centrality within the scope of the nearly neutral theory of evolution to predict genetic diversity in a tropical conifer species-pair

Jorge Cruz Nicolás, Gustavo Ibrahim Gilés Pérez, Andrés Lira Noriega, Norberto Martínez-Méndez, Erika Aguirre-Planter, Luis E. Eguiarte & Juan Pablo Jaramillo Correa
Aim: Estimating genetic diversity is key for understanging biogeographic and evolutionary processes. However, gathering genetic information is not feasible for all taxa or populations, particularly in the tropical regions. Identifying proxies for inferring such values has thus become essential. Here, we built on the niche centrality hypothesis (NCH; or central-abundance hypothesis) and the nearly neutral theory of evolution (NNT) to identify some of such proxies using a montane tropical conifer species-pair as model. The NCH...

Data from: Ultraconserved elements reconstruct the evolution of the Chagas disease-vectoring kissing bugs (Reduviidae: Triatominae)

Troy J. Kieran, Eric R. L. Gordon, Alejandro Zaldivar-Riveron, Carlos N. Ibarra-Cerdena, Travis C. Glenn & Christiane Weirauch
With about 150 species, Triatominae, the kissing bugs, are the largest radiation of hematophagous species within the Hemiptera. Kissing bugs are the sole vectors of the causative agent of Chagas disease, a tropical neglected disease that affects millions, mostly in Central and South America. Surprisingly, given the medical importance of this group, the evolutionary origin of Triatominae from predatory assassin bug ancestors is still under debate and phylogenetic relationships among and within the five tribes...

The importance of the Mexican taxa of Asteraceae on the family phylogeny

Patricia Rivera
Asteraceae is the largest plant family in México with about 417 genera and 3,113 species, more than 60% of them endemic. Phylogenetic relationships at subfamily and tribal levels have been previously resolved employing both nuclear and plastid molecular markers. However, Asteraceae species native to Mexico have been underrepresented in such phylogenies. To tackle this issue, the taxon sampling of this study included 90 Asteraceae species native to México, four species from the Caribbean, 119 previously...

Idiosyncratic responses to drivers of genetic differentiation in the complex landscapes of Isthmian Central America

Adrián García-Rodríguez, Carlos Guarnizo, Andrew Crawford, Adrian Garda & Gabriel Costa
Isthmian Central America (ICA) is one of the most biodiverse regions in the world, hosting an exceptionally high number of species per unit area. ICA was formed < 25 million years ago and, consequently, its biotic assemblage is relatively young and derived from both colonization and in situ diversification. Despite intensive taxonomic work on the local fauna, the potential forces driving genetic divergences and ultimately speciation in ICA remain poorly studied. Here, we used a...

Duet codes do not enhance neighbour recognition in two closely related species of neotropical wrens

Esmeralda Quiros-Guerrero & Esmeralda Quiros-Guerrero
Numerous studies have shown that territorial animals exhibit less aggression in response to neighbours than to strangers, a phenomenon known as dear enemy effect. The influence of acoustic features, such as song type sharing and repertoire sizes, in neighbour recognition has been widely documented in male songbirds. However, few studies have focused on duetting species, and particularly on those where pairs have pair-specific duet codes (consistent associations of their individual phrase types). Given that each...

Landscape structure shapes the diversity of tree seedlings at multiple spatial scales in a fragmented tropical rainforest

Sergio Nicasio-Arzeta, Julieta Benítez-Malvido, Isela Zermeño-Hernández & Susana Maza-Villalobos
The maintenance of seedling diversity of animal-dispersed tree species is fundamental for the structure and function of forest patches in fragmented tropical rainforests. Nonetheless, the effects of landscape structure at different spatial scales on α- and β-diversity of tree seedling communities are recently explored. Using a multi-scale approach, we assessed the relative effect of landscape composition and configuration on α- and β-diversity of animal-dispersed seedlings within 16 forest patches in the Lacandona rainforest, Mexico. We...

Bird records and habitat covariates databases (11 species; Oaxaca 2016-2018)

Rubén Ortega-Álvarez, Esteban Berrones Benítez, Israel Medina Mena, Viviana Ruiz-Gutiérrez & J. Jaime Zúñiga-Vega
Assessing the impact of working landscapes on biodiversity and defining locally contextualized management guidelines for productive activities are key for sustainability. Occupancy dynamics provide information about sites in the landscape that are either avoided or preferred by populations through the estimation of extinction and colonization probabilities, respectively. We identified the habitat traits that affected colonization and extinction probabilities of target birds (forest-dependent, endemic, or conservation-concern species) within a Neotropical working landscape by using multi-season occupancy...

Cognitive maps in the wild: Revealing the use of metric information in black howler monkeys' route navigation

Miguel De Guinea, Alejandro Estrada, Anna Isola K. Nekaris & Sarie Van Belle
When navigating, wild animals rely on internal representations of the external world to take movement decisions – called “cognitive maps”. As a rule, flexible navigation is hypothesized to be supported by sophisticated spatial skills (i.e., Euclidean cognitive maps); however, constrained movements along habitual routes is the most commonly reported navigation strategy. Even though incorporating metric information (i.e., distances and angles between locations) in route-based cognitive maps would likely enhance an animal’s navigation efficiency, there has...

Prosopis laevigata microsatellite and sequence alignment data

Antonio González-Rodríguez, Gonzalo Contreras-Negrete, Luis Letelier & Javier Piña-Torres
Patterns of genetic and phylogeographic structure and recent population history of plant species in the Mexican arid zones has been scarcely investigated. Prosopis laevigata is the most widely spread species of mesquite in Mexico, with extensive populations in the arid and semi-arid zones of the central and northern plateaus and scattered presence in southern Mexico. We evaluated the genetic and phylogeographic structure of this species to infer its recent demographic history. We genotyped six nuclear...

Competitive effects of a dominant palm on sapling performance in a Neotropical rainforest

Miguel Martínez-Ramos, Karen Noriega-Piña, Daniel Piñero & Teresa Valverde
Eradication of herbivores, due to human disturbances, produces a demographic outburst of highly competitive prey species, which in turn reduces plant species diversity. This happens at Los Tuxtlas tropical rainforest, Mexico, where a population outburst of the understory palm Astrocaryum mexicanum is ostensibly excluding tree species, but how this is occurring is still unknown. We used a neighborhood approach to explore the effects of palm shading and palm crowding on the survival and growth (RGR)...

Data from: Mate fidelity in a polygamous shorebird, the snowy plover (Charadrius nivosus)

Naerhulan Halimubieke, José Valdebenito, Philippa Harding, Medardo Cruz-López, Martín Serrano-Meneses, Richard James, Krisztina Kupán & Tamas Szekely
Social monogamy has evolved multiple times and is particularly common in birds. However, it is not well understood why some species live in long-lasting monogamous partnerships while others change mates between breeding attempts. Here, we investigate mate fidelity in a sequential polygamous shorebird, the snowy plover (Charadrius nivosus), a species in which both males and females may have several breeding attempts within a breeding season with the same or different mates. Using six years of...

Allopatric instead of parapatric divergence in an ectomycorrhizal fungus (Laccaria trichodermophora) in tropical sky-islands

Christian Quintero-Corrales, Rodolfo Ángeles-Argáiz, Juan Pablo Jaramillo-Correa, Daniel Piñero, Roberto Garibay-Orijel & Alicia Mastretta-Yanes
In tropical sky-islands, cold-affinity populations tend to become isolated at highlands during the interglacial periods, and to expand into the lowlands where they become more connected during the glacial periods. Although this has been widely studied in trees, it is poorly understood how fungal symbionts can differentiate among mountains (allopatrically), or within a single mountain (parapatrically) due to climate fluctuations. Here, we conducted population genomic analyses on the ectomycorrhizal fungus Laccaria trichodermophora in three tropical...

Anticipating the potential impacts of Batrachochytrium salamandrivorans on Neotropical salamander diversity

Adrián García-Rodríguez, M. Delia Basanta, Mirna G. García-Castillo, Héctor Zumbado-Ulate, Kelsey Neam, Sean Rovito, Catherine L. Searle & Gabriela Parra-Olea
Emergent infectious disease caused by the fungal pathogens Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal) represent one of the major causes of biodiversity loss in amphibians. While Bd has affected amphibians worldwide, Bsal remains restricted to Asia and Europe, but also could be a major threat for salamanders in the Western hemisphere, including the 320 bolitoglossine species described. Here we predict the suitable areas for Bsal in the Neotropics and assessed its potential impact on...

Data from: Thermal physiology responds to interannual temperature shifts in a montane horned lizard, Phrynosoma orbiculare

Brooke Bodensteiner, Saúl Domínguez-Guerrero, Fausto Méndez-De La Cruz, Martha Muñoz, Alexis Pardo-Ramírez & David Aguillón-Gutierrez
As climate change marches on, rapidly rising temperatures shatter records every year, presenting ever‐growing physiological challenges to organisms worldwide. Ectotherms rely on behavioral and physiological plasticity to contend with environmental fluctuations. Nonetheless, our understanding of thermal plasticity has been largely limited to laboratory settings. Here, we test whether aspects of thermal physiology respond to interannual shifts in thermal environment in a natural population of Phrynosoma orbiculare, a montane horned lizard, from Hidalgo, Mexico. At our...

Systematics of Vigna subgenus Lasiospron (Benth.) Maréchal et al. (Leguminosae: Papilionoideae: Phaseolinae)

Alfonso Delgado, Matt Lavin, Cristiane Snak & Gwilym Lewis
A taxonomic treatment is herein provided for the six primarily Neotropical species of Vigna subg. Lasiospron. This subgenus is distinguished, in part, by its close relationship with Old World Vigna species, but rather than having an Old World Vigna floral asymmetry where distal floral parts can have a right-hand curvature (from a face-view perspective), distal parts of subg. Lasiospron flowers, like those of American Phaseolinae, curve to the left. Our proposed taxonomy reflects published phylogenetic...

A non-parametric model-free analysis of actigraphic recordings of acute insomnia patients

Arlex Marín-García, Ruben Fossion, Markus Franziskus Müller, Wady Ríos-Herrera & Ana Leonor Rivera
Both parametric and non-parametric approaches to time series analysis have advantages and disadvantages. Parametric methods, although powerful and widely used, can yield inconsistent results due to the oversimplification of the observed phenomena, they require the setting of arbitrary constants for their creation and refinement, and, although these constants relate to assumptions about the observed systems, it can lead to erroneous results when treating a very complex problem with a sizable list of unknowns. Their non-parametric...

Data for: The interplay of environmental cues and wood density in the vegetative and reproductive phenology of seasonally dry tropical forest trees

Adriana L. Luna-Nieves, Edgar J. González, Jorge Cortés-Flores, Guillermo Ibarra-Manríquez, Axel Maldonado-Romo & Jorge A. Meave
The great phenological diversification characteristic of seasonally dry tropical forests (SDTF) suggests that these patterns result from a complex interplay between exogenous (e.g., climatic) and endogenous (e.g., morphological, physiological, anatomical) factors. Based on the well-established relationships of wood density with water-storing capacity and cavitation vulnerability in woody plants, we hypothesized differential vegetative and reproductive phenological responses to environmental cues for hardwood and softwood species. To test this hypothesis, we compared phenological patterns of pairs of...

Functional divergence from ecological baselines on Caribbean coral reefs

Sara M. Melo-Merino, Andrés Lira-Noriega, F. Javier González-Barrios, Héctor Reyes-Bonilla & Lorenzo Álvarez-Filip
Understanding how emergent ecological assemblages have diverged from natural states is fundamental in predicting future functioning and services of ecosystems. Coral reefs are of particular concern due to their high susceptibility to anthropogenic stressors. Yet, little is known about their pre-disturbance ranges of natural states, and most reports of decline are based on a limited number of sites and high levels of uncertainty. Here, we used a novel approach to estimate the physical functionality of...
