Data from: Phylogeography and population differentiation in the Psittacanthus calyculatus (Loranthaceae) mistletoe: a complex scenario of climate-volcanism interaction along the Trans-Mexican Volcanic Belt

María José Pérez-Crespo, Juan Francisco Ornelas, Antonio González-Rodríguez, Eduardo Ruiz-Sanchez, Antonio Acini Vásquez-Aguilar & Santiago Ramírez-Barahona
Aim The formation of the Trans-Mexican Volcanic Belt (TMVB) played an important role in driving inter- and intraspecific diversification at high elevations. However, Pleistocene climate changes and ecological factors might also contribute to plant genetic structuring along the volcanic belt. Here, we analysed phylogeographic patterns of the parrot-mistletoe Psittacanthus calyculatus to determine the relative contribution of these different factors. Location Trans-Mexican Volcanic Belt Methods Using nuclear and chloroplast DNA sequence data for 370 individuals, we...

Lewis, Sol Milne, Isaiah Mwesige … & Eleanor M. Slade
Biotic interactions underlie ecosystem structure and function, but predicting interaction outcomes is difficult. We tested the hypothesis that biotic interaction strength increases toward the equator, using a global experiment with model caterpillars to measure predation risk. Across an 11,660-kilometer latitudinal gradient spanning six continents, we found increasing predation toward the equator, with a parallel pattern of increasing predation toward lower elevations. Patterns across both latitude and elevation were driven by arthropod predators, with no systematic...

Data from: Development of a genotype-by-sequencing immunogenetic assay as exemplified by screening for variation in red fox with and without endemic rabies exposure

Michael E. Donaldson, Yessica Rico, Karsten Hueffer, Halie M. Rando, Anna V. Kukekova & Christopher J. Kyle
Pathogens are recognized as major drivers of local adaptation in wildlife systems. By determining which gene variants are favored in local interactions among populations with and without disease, spatially explicit adaptive responses to pathogens can be elucidated. Much of our current understanding of host responses to disease comes from a small number of genes associated with an immune response. High-throughput sequencing (HTS) technologies, such as genotype-by-sequencing (GBS), facilitate expanded explorations of genomic variation among populations....

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: 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: Primates adjust movement strategies due to changing food availability

Animals are hypothesized to search their environments in predictable ways depending on the distribution of resources. Evenly distributed foods are thought to be best exploited with random Brownian movements; while foods that are patchy or unevenly distributed require non-Brownian strategies, such as Lévy walks. Thus, when food distribution changes due to seasonal variation, animals should show concomitant changes in their search strategies. We examined this issue in six monkey species from Africa and Mexico: three...

Data from: Condition-dependent female preference for male genitalia length is based on male reproductive tactics

Armando Hernandez-Jimenez & Oscar Rios-Cardenas
There is extensive morphological variation of male genitalia across animals with internal fertilization, even among closely related species. Most studies attempting to explain this extraordinary diversity have focused on processes that occur post-copula (e.g. sperm competition, cryptic female choice). Only a few studies have focused on the pre-copula process of female preference. In addition, the extent to which this variation could be associated with the use of different reproductive tactics has yet to be explored....

Data from: Taxonomic and functional ant diversity along a secondary successional gradient in a tropical forest

Maya Rocha-Ortega, Xavier Arnan, José Domingos Ribeiro-Neto, Inara R. Leal, Mario E. Favila & Miguel Martínez-Ramos
The taxonomic diversity (TD) of tropical flora and fauna tends to increase during secondary succession. This increase may be accompanied by changes in functional diversity (FD), although the relationship between TD and FD is not well understood. To explore this relationship, we examined the correlations between the TD and FD of ants and forest age in secondary forests at the α- and β-diversity levels using single- and multi-trait-based approaches. Our objectives were to understand ant...

Data from: Prelude to a panzootic: gene flow and immunogenetic variation in northern little brown myotis vulnerable to bat white-nose syndrome

Christina M. Davy, Michael E. Donaldson, Yessica Rico, Cori L. Lausen, Kathleen Dogantzis, Kyle Ritchie, Craig K. R. Willis, Douglas W. Burles, Thomas S. Jung, Scott McBurney, Allysia Park, Donald J. McAlpine, Karen F. Vanderwolf, Christopher J. Kyle & Craig K.R. Willis
The fungus that causes bat white-nose syndrome (WNS) recently leaped from eastern North America to the Pacific Coast. The pathogen’s spread is associated with the genetic population structure of a host (Myotis lucifugus). To understand the fine-scale neutral and immunogenetic variation among northern populations of M. lucifugus, we sampled 1142 individuals across the species’ northern range. We used genotypes at 11 microsatellite loci to reveal the genetic structure of, and directional gene flow among, populations...

Data from: The conquering of North America: dated phylogenetic and biogeographic inference of migratory behavior in bee hummingbirds

Yuyini Licona-Vera & Juan Francisco Ornelas
Background: Geographical and temporal patterns of diversification in bee hummingbirds (Mellisugini) were assessed with respect to the evolution of migration, critical for colonization of North America. We generated a dated multilocus phylogeny of the Mellisugini based on a dense sampling using Bayesian inference, maximum-likelihood and maximum parsimony methods, and reconstructed the ancestral states of distributional areas in a Bayesian framework and migratory behavior using maximum parsimony, maximum-likelihood and re-rooting methods. Results: All phylogenetic analyses confirmed...

Data from: Aerobic power and flight capacity in birds: a phylogenetic test of the heart-size hypothesis

Roberto F. Nespolo, Cesar González-Lagos, Jaiber J. Solano-Iguaran, Magnus Elfwing, Alvaro Garitano-Zavala, Santiago Mañosa, Juan Carlos Alonso & Jordi Altamiras
Flight capacity is one of the most important innovations in animal evolution; it only evolved in insects, birds, mammals and the extinct pterodactyls. Given that powered flight represents a demanding aerobic activity, an efficient cardiovascular system is essential for the continuous delivery of oxygen to the pectoral muscles during flight. It is well known that the limiting step in the circulation is stroke volume (the volume of blood pumped from the ventricle to the body...

Data from: Habitat fragmentation and the prevalence of parasites (Diptera, Streblidae) on three Phyllostomid bat species

Beatriz Bolívar-Cimé, Alan Cuxim-Koyoc, Enrique Reyes-Novelo, Juan B. Morales-Malacara, Javier Laborde & Rafael Flores-Peredo
Ectoparasitism in bats seems to be influenced strongly by the type of roost preferred by the hosts, and group size; however, the effect of habitat loss and fragmentation on the prevalence of ectoparasites in bats has scarcely been studied. In northeastern Yucatan, Mexico, we estimated the prevalence of infestation by Streblidae flies in three phyllostomid bat species with different roost preferences (caves, trees, or both) in two types of landscape matrices (tropical semi-deciduous forest and...
