Environmental correlates of Leguminosae species richness in Mexico: quantifying the contributions of energy and environmental seasonality

Maribel Arenas-Navarro, Oswaldo Téllez-Valdés, Gabriel López-Segoviano, Miguel Murguía-Romero & Sebastián Tello
Explaining species richness patterns is a central issue in ecology, but a general explanation remain elusive. Environmental conditions have been proposed to be important drivers of these patterns, but we still need to better understand the relative contribution of environmental factors. Here we aim at testing two environmental hypotheses for richness gradients: energy availability and environmental seasonality using diversity patterns of the family Leguminosae across Mexico. We compiled a database of 502 species and 32,962...

Data from: Background matching, disruptive coloration and differential use of microhabitats in two neotropical grasshoppers with sexual dichromatism

Víctor Hugo Ramírez-Delgado & Raúl Cueva Del Castillo
Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration-matching and disruptive coloration. Disruptive coloration may evolve in visually heterogeneous microhabitats, whereas background matching could be favored in chromatically homogeneous microhabitats. In this work, we used digital photography to explore the potential use of disruptive coloration and background matching in males and females of two grasshopper species of the Sphenarium genus in different habitats. We found chromatic differences...

Data from: Immune response declines with age in a wild lizard

Melissa Plasman, Estela Sandoval-Zapotitla & Roxana Torres
The immune system allows animals to survive the constant attacks of pathogens. Even though it is essential for survival and fitness, the performance of the immune system can decline with age -a process known as immunosenescence- which may be responsible for the increased mortality of older individuals. There are few studies regarding the effect of age on the immune system in reptiles, and no evidence of immunosenescence has yet been reported in lizards. In a...

Data from: High genetic diversity and stable Pleistocene distributional ranges in the widespread Mexican red oak Quercus castanea Née (1801) (Fagaceae)

Juan Manuel Peñaloza-Ramírez, Hernando Rodríguez-Correa, Antonio González-Rodríguez & Ken Oyama
The Mexican highlands are areas of high biological complexity where taxa of Nearctic and Neotropical origin and different population histories are found. To gain a more detailed view of the evolution of the biota in these regions, it is necessary to evaluate the effects of historical tectonic and climate events on species. Here, we analyzed the phylogeographic structure, historical demographic processes, and the contemporary period, Last Glacial Maximum (LGM) and Last Interglacial (LIG) ecological niche...

Data from: Solitary ecology as a phenomenon extending beyond insular systems: exaptive evolution in Anolis lizards

Julián A. Velasco, Steven Poe, Constantino González-Salazar & Oscar Flores-Villela
The mechanisms driving phenotypic evolution have been of interest to biologists since Darwin. Ecological release—wherein adaptive evolution occurs following relaxation of constraining selective pressures—and environmental filtering—wherein exaptive traits allow colonization of a new area—have been studied in several insular cases. Anolis lizards, which may exist in solitude or sympatry with multiple congeners, are an excellent system for evaluating whether ecological release and environmental filtering are associated with phenotypic shifts across phylogenetic and geographical scales. Insular...

El Camino Tierra Adentro as a rural landscape

Graciela Mota, Pilar Rincón & Sara E. Narvaez Martínez
Camino Real de Tierra Adentro was the Royal Inland Road, also known as the Silver Route. The inscribed property consists of 55 sites and five existing World Heritage sites lying along a 1400 km section of this 2600 km route, that extends north from Mexico City to Texas and New Mexico, United States of America. The route was actively used as a trade route for 300 years, from the mid-16th to the 19th centuries, mainly...

In vitro impact of distinct FSH glycosylation variants on FSH receptor-stimulated signal transduction and functional selectivity

Alfredo Ulloa-Aguirre
Follicle-stimulating hormone (FSH) exists as different major glycoforms that differ in glycosylation of the hormone-specific β-subunit. Tetra-glycosylated FSH (FSH24) and tri-glycosylated FSH (FSH21) are the most abundant forms found in humans. Employing distinct readouts in HEK293 cells stably expressing the human FSH receptor, we here compared intracellular signaling triggered by human pituitary FSH preparations (FSH21and FSH24) as well as by equine FSH (eFSH), and human recombinant FSH (recFSH), each exhibiting distinct glycosylation patterns. The potencies...

Data from: Dung beetle activity affects rainforest seed bank dynamics and seedling establishment

Lina Adonay Urrea-Galeano, Ellen Andresen, Rosamond Coates, Francisco Mora Ardila & Guillermo Ibarra-Manríquez
Dung beetles relocate vertebrate feces under the soil surface, and this behavior has many ecological consequences. In tropical forests, for example, seeds defecated by mammals that are subsequently buried by dung beetles are less likely to suffer predation. While the effects of dung beetles on the fate of defecated seeds have been relatively well studied, their effect on seeds already buried in the soil has not. To contribute to fill this gap we designed a...

Data from: The sex determination pattern in crocodilians: a systematic review after three decades of research

Edgar Javier González, Marcela Martínez-López, Marco Antonio Morales-Garduza, Rodrigo García-Morales, Pierre Charruau & José Alberto Gallardo Cruz
1. Sex in crocodilians is not determined by chromosomes, but by egg incubation temperature, where different temperatures produce different clutch sex ratios. Two patterns have been proposed to describe these changes in sex ratios: a 100% female proportion at low and high temperatures with male predominance at intermediate ones (FMF) or a simpler pattern with a single female to male transition (FM). Over the last three decades, researchers have provided empirical information to support either...

Data from: Adsorption and corrosion inhibition behavior of new theophylline-triazole based derivatives for steel in acidic medium

Araceli Espinoza-Vázquez, Francisco Javier Rodríguez Gómez, Ivonne Karina Martínez-Cruz, Deyanira Ángeles-Beltrán, Guillermo Enrique Negrón-Silva, Manuel Palomar-Pardavé, Leticia Lomas Romero, Diego Pérez Martínez & Alejandra M. Navarrete-López
The design and synthesis of a series of theophylline derivatives containing 1,2,3-triazole moieties is presented. The corrosion inhibition activities of these new triazole-theophylline compounds were evaluated by studying the corrosion of API 5L X52 steel in 1 M HCl media. The results showed that an increase in the concentration of the theophylline-triazole derivatives also increases the charge transference resistance (Rct) value, enhancing inhibition efficiency and decreasing the corrosion process. The electrochemical impedance spectroscopy under static...

West Nile Virus evolves at the pace of its avian hosts’ life-history

Gabriel Ernesto García Peña
Disease resistant hosts are central in the spread, persistence, adaptation and diversification of infectious pathogens. In theory, resistant hosts must compromise on reproduction and invest more energy in self maintenance and immune defence. Here we investigated these hypotheses on the emergence of West Nile Virus (WNV) from 1999 to 2012 in the United States, when the virus caused mass mortality in some bird species. Our study comprehends two steps: First, we used regression tree meta-analysis...

Biotic predictors with phenological information improve range estimates for migrating monarch butterflies in Mexico

Jamie M. Kass, Robert P. Anderson, Alejandro Espinosa-Lucas, Verónica Juárez-Jaimes, Esteban Martínez-Salas, Francisco Botello, Gloria Tavera, José Juan Flores-Martínez & Víctor Sánchez-Cordero
Although long-standing theory suggests that biotic variables are only relevant at local scales for explaining the patterns of species’ distributions, recent studies have demonstrated improvements to species distribution models (SDMs) by incorporating predictor variables informed by biotic interactions. However, some key methodological questions remain, such as which kinds of interactions are permitted to include in these models, how to incorporate the effects of multiple interacting species, and how to account for interactions that may have...

Species richness of urban and rural fish assemblages in the Grijalva Basin floodplain, southern Gulf of Mexico

Alberto J. Sánchez, Nicolás Álvarez-Pliego, Héctor Espinosa-Pérez, Rosa Florido, Alberto Macossay-Cortez, Everardo Barba, Miguel Ángel Salcedo & Arturo Garrido-Mora
Urban sprawl poses a major threat to aquatic biodiversity. The species richness in fish assemblages of fifteen ecosystems with different degrees of hydraulic connectivity in the floodplain of the Grijalva River watershed has been analysed and described along five years. After human interventions, four lagoons are permanently disconnected and three are temporarily connected. The other three lagoons stay permanently interconnected. Native cichlids and poeciliids dominated in number of species, representing 24 of the 55 listed...

Data from: Plastic multicellular development of Myxococcus xanthus: genotype-environment interactions in a physical gradient

Natsuko Rivera-Yoshida, Alejandro Arzola, Juan Antonio Arias Del Angel, Alessio Franci, Michael Travisano, Ana E. Escalante & Mariana Benítez
In order to investigate the contribution of the physical environment to variation in multicellular development of Myxococcus xanthus, phenotypes developed by different genotypes in a gradient of substrate stiffness conditions were quantitatively characterized. Statistical analysis showed that plastic phenotypes result from the genotype, the substrate conditions and the interaction between them. Also, phenotypes were expressed in two distinguishable scales, the individual and the population levels, and the interaction with the environment showed scale and trait...

The spatial analysis of biological interactions: morphological variation responding to the co-occurrence of competitors and resources

Leonel Herrera-Alsina, Rosa Daniela Tovilla-Sierra, Rafael Bribiesca & Hector T Arita
By sharing geographic space, species are forced to interact with one another and the contribution of this process to evolutionary and ecological patterns of individual species is not fully understood. At the same time, species turnover makes that species composition varies from one area to another, so the analysis of biological interaction cannot be uncoupled from the spatial context. This is particularly important for clades that show high degree of specialization such as hummingbirds, where...

Beyond pairwise interactions: multispecies character displacement in Mexican freshwater fish communities

Andrea J Roth-Monzón, Mark C Belk, J. Jaime Zúñiga-Vega & Jerald B Johnson
Competition has long been recognized as a central force in shaping evolution, particularly through character displacement. Yet research on character displacement is biased as it has focused almost exclusively on pairs of interacting species, while ignoring multispecies interactions. Communities are seldom so simple that only pairs of species interact, and it is not clear if inferences from pairwise interactions are sufficient to explain patterns of phenotypes in nature. Here we test for character displacement in...

Data from: A metadata approach to evaluate the state of ocean knowledge: strengths, limitations, and application to Mexico

Juliano Palacios-Abrantes, Andrés M. Cisneros-Montemayor, Miguel A. Cisneros-Mata, Laura Rodríguez, Francisco Arreguín-Sánchez, Veronica Aguilar, Santiago Domínguez-Sánchez, Stuart Fulton, Raquel López-Sagástegui, Hector Reyes-Bonilla, Rocio Rivera-Campos, Silvia Salas, Nuno Simoes & William W. L. Cheung
Climate change, mismanaged resource extraction, and pollution are reshaping global marine ecosystems with direct consequences on human societies. Sustainable ocean development requires knowledge and data across disciplines, scales and knowledge types. Although several disciplines are generating large amounts of data on marine socio-ecological systems, such information is often underutilized due to fragmentation across institutions or stakeholders, limited standardization across scale, time or disciplines, and the fact that information is often not searchable within existing databases....

Data from: Species diversification in a lineage of Mexican red oak (Quercus section Lobatae subsection Racemiflorae)—the interplay between distance, habitat, and hybridization

Ross A. McCauley, Aurea C. Cortés-Palomec & Ken Oyama
In widespread taxa in which hybridization is suspected of being an important aspect of species biology, the patterns and drivers of lineage diversification are not always clear. Here, we examine the patterns of species diversification in a monophyletic lineage of oaks endemic to western Mexico, a center of global oak diversity. This group of four species inhabits a variety of soil types and exhibits varying patterns of species distribution ranging from widespread to restricted, with...

Data from: Infection with Batrachochytrium dendrobatidis is common in tropical lowland habitats: implications for amphibian conservation

Hector Zumbado-Ulate, Adrián García-Rodríguez, Vance T. Vredenburg & Catherine Searle
Numerous species of amphibians declined in Central America during the 1980s and 1990s. These declines mostly affected highland stream amphibians and have been primarily linked to chytridiomycosis, a deadly disease caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd). Since then, the majority of field studies on Bd in the Tropics have been conducted in midland and highland environments (>800 m) mainly because the environmental conditions of mountain ranges match the range of ideal abiotic conditions...

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...

Life history plasticity and water use trade-offs associated with drought resistance in a clade of California jewelflowers

Sharon Strauss, Ian Pearse, Jessica Aguilar, Patrick McIntyre & N. Ivalu Cacho
Water limitation is a primary driver of plant geographic distributions and individual plant fitness. Drought resistance is the ability to survive and reproduce despite limited water, and numerous studies have explored its physiological basis in plants. However, it is unclear how drought resistance and trade-offs associated with drought resistance evolve within plant clades. We quantified the relationship between water availability and fitness for 13 short-lived plant taxa in the Streptanthus clade that vary in their...
