Data from: Ecomorphological convergence in Eleutherodactylus frogs: a case of replicate radiations in the CaribbeanÁlvaro Dugo-Cota, Carles Vilà, Ariel Rodríguez & Alejandro Gonzalez-Voyer
Replicate radiations, the repeated multiplication of species associated with ecological divergence, have attracted much attention and generated as much debate. Due to the few well‐studied cases, it remains unclear whether replicate radiations are an exceptional result of evolution or a relatively common example of the power of adaptation by natural selection. We examined the case of Eleutherodactylus frogs, which radiated in the Caribbean islands resulting in more than 160 species that occupy very diverse habitats....
1.Despite great interest in metrics to quantify the structure of ecological networks, the effects of sampling and scale remain poorly understood. In fact, one of the most challenging issues in ecology is how to define suitable scales (i.e., temporal or spatial) to accurately describe and understand ecological systems. 2.Here, we sampled a series of ant‐plant interaction networks in the southern Brazilian Amazon rainforest in order to determine whether the spatial sampling scale, from local to...
Data from: Host plant phylogeny and abundance predict root-associated fungal community composition and diversity of mutualists and pathogensJohn W. Schroeder, Jessica T. Martin, Diego F. Angulo, Itzel Arias-Del Razo, Jomar M. Barbosa, Ramón Perea, Esther Sebastián-González & Rodolfo Dirzo
• Interactions between plants and their root-associated fungi (RAF) may influence the relative abundance of tree species and determine forest community diversity. Such plant-soil feedbacks in turn depend on the degree to which spatial distance and phylogenetic relatedness of host trees structure pathogen and mutualist communities, but research detailing these aspects of RAF communities is lacking. Here, we characterize plant-RAF associations across a diverse plant community, focusing on the degree to which RAF communities are...
Data from: Games academics play and their consequences: how authorship, h-index, and journal impact factors are shaping the future of academiaJan Gogarten, Colin Chapman, Julio Bicca-Marques, Sébastien Calvignac-Spencer, Pengfei Fan, Peter Fashing, Songtao Guo, Claire Hemingway, Fabian Leendertz, Baoguo Li, Ikki Matsuda, Rong Hou, Juan Carlos Serio-Silva & Nils Chr. Stenseth
Research is a highly competitive profession where evaluation plays a central role; journals are ranked and individuals are evaluated based on their publication number, the number of times they are cited, and their h-index. Yet, such evaluations are often done in inappropriate ways that are damaging to individual careers, particularly for young scholars, and to the profession. Furthermore, as with all indices, people can play games to better their scores. This has resulted in the...
Data from: Taxonomic and functional diversity of the co-flowering community differentially affect Cakile edentula pollination at different spatial scalesCristopher Albor, José García-Franco, Victor Parra-Tabla, Cecilia Díaz-Castelazo & Gerardo Arceo-Gomez
1. The number of co-flowering species, floral density and floral trait diversity can be major determinants of pollinator-mediated plant-plant interactions in a community. However, evaluation of how each one of these co-flowering components affects the pollination success of a single focal plant species, and how these effects vary at different spatial scales, is lacking. 2. Here we evaluated the effects of functional diversity (flower morphology and colour), taxonomic diversity (reflecting potential sampling effects) and flower...
Aim To test hypotheses on the origin and assembly of the flora of the Chihuahuan Desert using as a system the hard-leaved shrubby lineages of the Rosaceae distributed in North American Deserts. Location North American Deserts, Chihuahuan Desert, Mexican Plateau, Tehuacán Valley. Methods Phylogenetic analyses were conducted based on nine chloroplast and nuclear molecular markers of eleven newly sequenced species of Rosaceae distributed in the Chihuahuan Desert along with previous sequences of 41 species in...
Data from: Are there synergistic or antagonistic effects of multiple maternally-derived egg components (antibodies and testosterone) on offspring phenotype?Roxana Torres, Eunice Chin, Rowan Rampton & Tony D. Williams
Eggs are multivariate in that they contain multiple maternally-derived egg components (e.g. hormones, antibodies, mRNA, antioxidants) which are thought to influence offspring phenotype. However, most studies have focused on single egg components and on short-term effects. Here, we simultaneously manipulated two egg components, maternally-derived antibodies (MAb) and yolk testosterone (T) to assess potential synergistic or antagonistic effects on offspring phenotype from hatching to sexual maturity. We found no evidence for short-or long-term effects of either...
Data from: Estimated six percent loss of genetic variation in wild populations since the industrial revolutionDeborah M. Leigh, Andrew P. Hendry, Ella Vázquez-Domínguez & Vicki L. Friesen
Genetic variation is fundamental to population fitness and adaptation to environmental change. Human activities are driving declines in many wild populations and could have similar effects on genetic variation. Despite the importance of estimating such declines, no global estimate of the magnitude of ongoing genetic variation loss has been conducted across species. By combining studies that quantified recent changes in genetic variation across a mean of 27 generations for 91 species, we conservatively estimate a...
Data from: Contrasting colonization patterns of black mangrove (Avicennia germinans (L.) L.) gene pools along the Mexican coastsMaried Ochoa-Zavala, Juan Pablo Jaramillo-Correa, Daniel Piñero, Alejandro Nettel & Juan Núñez-Farfán
Aim: Historical and geological events can impact the genetic structure of species, producing signatures that vary among taxa and gene pools within taxa. Such signatures can also be affected by local geography and tolerance to environmental conditions. However, disentangling of different drivers of population structure is often difficult. In an attempt to do so, we surveyed two independent gene pools of the same species that followed similar paths of postglacial colonization across contrasting landscapes and...
Data from: Testing the Distraction Hypothesis: do extrafloral nectaries reduce ant‐pollinator conflict?Nora Villamil, Karina Boege & Graham N. Stone
1. Ant guards protect plants from herbivores, but can also hinder pollination by damaging reproductive structures and/or repelling pollinators. Natural selection should favour the evolution of plant traits that deter ants from visiting flowers during anthesis, without waiving their defensive services. The Distraction Hypothesis posits that rewarding ants with extrafloral nectar could reduce their visitation of flowers, reducing ant-pollinator conflict while retaining protection of other structures. 2. We characterised the proportion of flowers occupied by...
Data from: Plastic multicellular development of Myxococcus xanthus: genotype-environment interactions in a physical gradientNatsuko 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...
