The evolution of sexually dimorphic traits in ecological gradients: An interplay between natural and sexual selection in hummingbirds

Diego F. Beltrán, Marcelo Araya-Salas, Juan Parra, F. Gary Stiles & Alejandro Rico-Guevara
Traits that exhibit differences between the sexes have been of special interest in the study of phenotypic evolution. Classic hypotheses explain sexually dimorphic traits via intrasexual competition and mate selection, yet natural selection may also act differentially on the sexes to produce dimorphism. Natural selection can act either through physiological and ecological constraints on one of the sexes or by modulating the strength of sexual/social selection. This predicts an association between the degree of dimorphism...

Data from: The Odonate Phenotypic Database, a new open data resource for comparative studies of an old insect order

John T. Waller, Beatriz Willink, Maximilian Tschol & Erik I. Svensson
We present The Odonate Phenotypic Database (OPD): an online data resource of dragonfly and damselfly phenotypes (Insecta: Odonata). Odonata is a relatively small insect order that currently consists of about 6400 species belonging to 32 families. The database consists of a variety of morphological, life-history and behavioral traits, and biogeographical information collected from literature sources. We see taxon-specific phenotypic databases from Odonata and other organismal groups as becoming an increasing valuable resource in comparative studies....

Individual signatures outweigh social group identity in contact calls of a communally nesting parrot

Grace Smith-Vidaurre, Marcelo Araya-Salas & Timothy F. Wright
Despite longstanding interest in the evolutionary origins and maintenance of vocal learning, we know relatively little about how social dynamics influence vocal learning processes in natural populations. The “social group membership” hypothesis proposes that socially learned calls evolved and are maintained as signals of group membership. However, in fission-fusion societies, individuals can interact in social groups across various social scales. For learned calls to signal group membership over multiple social scales, they must contain information...

Global biogeography and diversification of a group of brown seaweeds (Phaeophyceae) driven by clade-specific evolutionary processes

Christophe Vieira, Frederique Steen, Sofie D'hondt, Quinten Bafort, Cindy Fernandez-García, Brian Wysor, Lennert Tyberghein, Ana Tronholm, Lydiane Mattio, Claude Payri, Gary Saunders, Frederik Leliaert, Heroen Verbruggen & Olivier De Clerck
Aim: Historical processes that shaped current diversity patterns of seaweeds remain poorly understood. Using Dictyotales, a globally distributed order of brown seaweeds as a model, we test if historical biogeographical and diversification patterns are comparable across clades. Dictyotales contain some 22 genera, three of which, Dictyota, Lobophora and Padina, are exceptionally diverse. Specifically we test if the evolutionary processes in these clades that shaped their latitudinal diversity patterns are in line with the tropical conservatism,...

Data from: Relative selectivity of plant cardenolides for Na+/K+-ATPases from the monarch butterfly and non-resistant insects

Georg Petschenka, Colleen S. Fei, Juan J. Araya, Susanne Schröder, Barbara N. Timmermann & Anurag A. Agrawal
A major prediction of coevolutionary theory is that plants may target particular herbivores with secondary compounds that are selectively defensive. The highly specialized monarch butterfly (Danaus plexippus) copes well with cardiac glycosides (inhibitors of animal Na+/K+-ATPases) from its milkweed host plants, but selective inhibition of its Na+/K+-ATPase by different compounds has not been previously tested. We applied 17 cardiac glycosides to the D. plexippus-Na+/K+-ATPase and to the more susceptible Na+/K+-ATPases of two non-adapted insects (Euploea...

Data from: Rapid evolution of a floral trait following acquisition of novel pollinators

Christopher R. Mackin, Julián F. Peña, Mario A. Blanco, Nicholas J. Balfour & Maria Clara Castellanos
1. Changes in the pollinator assemblage visiting a plant can have consequences for reproductive success and floral evolution. We studied a recent plant trans-continental range expansion to test whether the acquisition of new pollinator functional groups can lead to rapid adaptive evolution of flowers. 2. In Digitalis purpurea, we compared flower visitors, floral traits and natural selection between native European populations and those in two Neotropical regions, naturalised after independent introductions. Bumblebees are the main...

Data from: Unrecognized coral species diversity masks differences in functional ecology

Jennifer N. Boulay, Michael E. Hellberg, Jorge Cortés, Iliana B. Baums & J. Cortes
Porites corals are foundation species on Pacific reefs but a confused taxonomy hinders understanding of their ecosystem function and responses to climate change. Here, we show that what has been considered a single species in the eastern tropical Pacific, Porites lobata, includes a morphologically similar yet ecologically distinct species, Porites evermanni. While P. lobata reproduces mainly sexually, P. evermanni dominates in areas where triggerfish prey on bioeroding mussels living within the coral skeleton, thereby generating...

Data from: A Mesoamerican origin of cherimoya (Annona cherimola Mill.). Implications for the conservation of plant genetic resources

Nerea Larranaga, Federico J. Albertazzi, Gustavo Fontecha, Margarita Palmieri, Heimo Rainer, Maarten Van Zonneveld & Jose I Hormaza
Knowledge on the structure and distribution of genetic diversity is a key aspect in order to plan and execute an efficient conservation and utilization of the genetic resources of any crop as well as for determining historical demographic inferences. In this work, a large data set of 1765 accessions of cherimoya (Annona cherimola Mill, Annonaceae), an underutilized fruit tree crop native to the neotropics and used as a food source by pre-Columbian cultures, was collected...

Global gradients in intraspecific variation in vegetative and floral traits are partially associated with climate and species richness

Jonas Kuppler, Cécile H. Albert, Gregory M. Ames, W. Scott Armbruster, Gerhard Boenisch, Florian C. Boucher, Diane R. Campbell, Liedson T. Carneiro, Eduardo Chacón-Madrigal, Brian J. Enquist, Carlos R. Fonseca, José M. Gómez, Antoine Guisan, Pedro Higuchi, Dirk N. Karger, Jens Kattge, Michael Kleyer, Nathan J. B. Kraft, Anne-Amélie C. Larue-Kontić, Amparo Lázaro, Martin Lechleitner, Deirdre Loughnan, Vanessa Minden, Ülo Niinemets, Gerhard E. Overbeck … & Robert R. Junker
Aim Intraspecific trait variation (ITV) within natural plant communities can be large, influencing local ecological processes and dynamics. Here, we shed light on how ITV in vegetative and floral traits responds to large-scale abiotic and biotic gradients (i.e. climate and species richness). Specifically, we tested if associations of ITV with temperature, precipitation and species richness were consistent with any of from four hypotheses relating to stress-tolerance and competition. Furthermore, we estimated the degree of correlation...

Data from: Phylogenetic systematics of subtribe Spiranthinae (Orchidaceae: Orchidoideae: Cranichideae) based on nuclear and plastid DNA sequences of a nearly complete generic sample

Gerardo A. Salazar, Joao A.N. Batista, Lidia I. Cabrera, Cassio Van Den Berg, W. Mark Whitten, Eric C. Smidt, Cristiano R. Buzatto, Rodrigo B. Singer, Gunter Gerlach, Rolando Jimenez-Machorro, Jose A. Radins, Irma S. Insaurralde, Leonardo R.S. Guimaraes, Fabio De Barros, Francisco Tobar, Jose L. Linares, Ernesto Mujica, Robert L. Dressler, Mario A. Blanco, Eric Hagsater & Mark W. Chase
Subtribe Spiranthinae is the most species-rich lineage of terrestrial Neotropical orchids, encompassing > 500 species and 40 genera. We conducted maximum parsimony and maximum likelihood phylogenetic analyses of DNA sequence data of plastid matK-trnK and trnL-trnF and nuclear ribosomal ITS sequences for 36 genera and 182 species of Spiranthinae plus appropriate outgroups. The results strongly support monophyly of Spiranthinae (minus Discyphus, Discyphinae and Galeottiella, Galeottiellinae) and five major lineages, namely monospecific Cotylolabium (sister to the...

Data from: Flower consumption, ambient temperature and rainfall modulate drinking behavior in a folivorous-frugivorous arboreal mammal

Óscar M. Chaves, Vanessa B. Fortes, Gabriela P. Hass, Renata B. Azevedo, Kathryn E. Stoner & Júlio César Bicca-Marques
In these datasets we provided information on the drinking behavior in 14 wild groups of brown howler monkeys (Alouatta guariba clamitans) inhabiting small, medium, and large Atlantic Forest fragments in southern Brazil. We provided two datasets: (1) full data on the drinking behavior of the 14 study groups, and (2) the dataset used to run the GLMMs described in the main manuscript. Overall, we found a wide variation in the mean rate of drinking among...

Data from: Gone with the rain: negative effects of rainfall on male mating success in a nest-building arachnid

Andrés Rojas, Diego Solano-Brenes, Danilo G. Muniz & Glauco Machado
In nest-building species, offspring survival and reproductive success of parental individuals are strongly influenced by nest quality. Thus, quantifying the influence of abiotic conditions on nest integrity is important to predict the effects of weather variability on the fitness of parental individuals. Here we investigated how rainfall affects nest integrity and how nest integrity influences males’ attractiveness and nest tenure. Our study species was the harvestman Quindina limbata, in which males build mud nests on...

Population structure and dynamics, breeding activity and phenology of the blue-sided treefrog (Agalychnis annae)

Viviana Arguedas, Marco D. Barquero & José Manuel Mora
Agalychnis annae is a species endemic to Costa Rica and Panama with populations shrinking or disappearing from several locations. We studied the reproduction of a relict population of A. annae in a 1,300 m2 natural pond in Costa Rica during 2007–2008. We marked adults with a visible implant alphanumeric tag injected in the thigh. We measured reproductive effort considering calling males per night and per hour, number of pairs in amplexus, and number of egg...

Canopy cover data from: Applied nucleation facilitates tropical forest recovery

Karen D. Holl, J. Leighton Reid, Rebecca J. Cole, Federico Oviedo‐Brenes, Juan A. Rosales & Rakan A. Zahawi
Applied nucleation, mostly based upon planting tree islands, has been proposed as a cost‐effective strategy to meet ambitious global forest and landscape restoration targets. We review results from a 15‐year study, replicated at 15 sites in southern Costa Rica, that compares applied nucleation to natural regeneration and mixed‐species tree plantations as strategies to restore tropical forest. We have collected data on planted tree survival and growth, woody vegetation recruitment and structure, seed rain, litterfall, epiphytes,...

Data from: Porcine colonization of the Americas: a 60k SNP story

M. Pérez-Enciso, William Burgos-Paz, Carla A. Souza, Hendrik Jan Megens, Yuliaxis Ramayo-Caldas, Maximo Melo, C. Lemús-Flores, Eduardo Caal, Henry W. Soto, Rodrigo Martínez, Luz A. Álvarez, Lenin Aguirre, Volga Iñiguez, M. A. Revidatti, O. R. Martínez-López, Silvia Llambi, Anna Esteve-Codina, M. C. Rodríguez, Richard P. M. A. Crooijmans, Samuel R. Paiva, Larry B. Schook & Martien A. M. Groenen
The pig, Sus scrofa, is a foreign species to the American continent. Although pigs originally introduced in the Americas should be related to those from the Iberian Peninsula and Canary islands, the phylogeny of current creole pigs that now populate the continent is likely to be very complex. Because of the extreme climates that America harbours, these populations also provide a unique example of a fast evolutionary phenomenon of adaptation. Here, we provide a genome...

Data from: Molecular phylogenetics and the evolution of fruit and leaf morphology of Dichaea (Orchidaceae: Zygopetalinae)

Kurt M. Neubig, Norris H. Williams, W. Mark Whitten & Franco Pupulin
BACKGROUND AND AIMS: The orchid genus Dichaea, with over 100 species found throughout the neotropics, is easily recognized by distichous leaves on long stems without pseudobulbs and flowers with infrastigmatic ligules. The genus has previously been divided into four sections based primarily on presence of ovary bristles and a foliar abscission layer. The aim of this work is to use DNA sequence data to estimate phylogenetic relationships within Dichaea and map the distribution of major...

Data from: Testing the link between population genetic differentiation and clade diversification in Costa Rican orchids

Yael Kisel, Alejandra C. Moreno-Letelier, Diego Bogarín, Martyn P. Powell, Mark W. Chase & Timothy G. Barraclough
Species population genetics could be an important factor explaining variation in clade species richness. Here we use newly generated AFLP data to test whether five pairs of sister clades of Costa Rican orchids that differ greatly in species richness also differ in average neutral genetic differentiation within species, expecting that if the strength of processes promoting differentiation within species is phylogenetically heritable, then clades with greater genetic differentiation should diversify more. Contrary to expectation, neutral...

Data from: The chimerical genome of Isla del Coco feral pigs (Costa Rica), an isolated population since 1793 but with remarkable levels of diversity

E. Bianco, H. W. Soto, L. Vargas & M. Perez-Enciso
The history of domestic species and of their wild ancestors is not a simple one, and feral processes can clarify key aspects of this history, including the adaptive processes triggered by new environments. Here, we provide a comprehensive genomic study of Isla del Coco (Costa Rica) feral pigs, a unique population that was allegedly founded by two individuals and has remained isolated since 1793. Using SNP arrays and genome sequencing, we show that Cocos pigs...

Data from: Changes in gene expression during female reproductive development in a colour polymorphic insect

Beatriz Willink, M. Catherine Duryea, Christopher Wheat & Erik I. Svensson
Pleiotropy (multiple phenotypic effects of single genes) and epistasis (gene interaction) have key roles in the development of complex phenotypes, especially in polymorphic taxa. The development of discrete and heritable phenotypic polymorphisms often emerges from major-effect genes that interact with other loci and have pleiotropic effects on multiple traits. We quantified gene expression changes during ontogenetic colour development in a polymorphic insect (damselfly: Ischnura elegans), with three heritable female morphs, one being a male mimic....

Data from: Association between rainfall seasonality and the flowering of epiphytic plants in a Neotropical montane forest

Alfredo Cascante-Marín, Christian Trejos & Ricardo Alvarado
The association between the reproductive phenology of epiphytic communities with environmental and ecological factors remains largely unexplored. Because epiphytes depend on environmental moisture, seasonal changes in moisture conditions likely act as the primary determinants of their reproductive timing. We examined whether water limitation or pollinator competition structures the flowering phenologies of an epiphytic community in a seasonal mountain forest in Costa Rica. Additionally, we addressed the environmental factors that might trigger floral induction. Using a...

Successional and phenological effects on plant-floral visitor interaction networks of a tropical dry forest

Jorge Cortés-Flores, Martha Lopezaraiza-Mikel, Martín De Santiago-Hernández, Silvana Marten-Rodriguez, Edson Jacob Cristobal Perez, María De Jesus Aguilar-Aguilar, Francisco Javier Balvino-Olvera, Roberto Carlos Sayago-Lorenzana, Oliverio Delgado-Carrillo, Eric J. Fuchs, Gumersindo Sánchez-Montoya & Mauricio Quesada
1. Plant-pollinator interactions are fundamental to ecosystem functioning; however, the role that succession and phenology have on these interactions is poorly understood, particularly in endangered tropical ecosystems. In highly diverse ecosystems such as tropical dry forests (TDF), variation in water and food availability determines the life cycles of animal pollinators. Therefore, understanding patterns of flowering phenology and plant-pollinator interactions across seasons in successional environments is key to maintaining and restoring TDF. 2. We analysed the...

2) A list of 30 different conservation projects on 17 primate species in Latin America.

Gone with the wind: Negative genetic and progeny fitness consequences of habitat fragmentation in the wind pollinated dioecious tree Brosimum alicastrum

MARIA DE JESUS AGUILAR-AGUILAR, EDSON JACOB CRISTOBAL PEREZ, Jorge A. Lobo, Eric J. Fuchs, Ken Oyama, Silvana Martén-Rodríguez, Yvonne Herrerías-Diego & Mauricio Quesada
Habitat fragmentation negatively affects population size and mating patterns that directly impact progeny fitness and genetic diversity; however, little is known about the effects of habitat fragmentation on dioecious, wind pollinated trees. We assessed the effects of habitat fragmentation on population sex ratios, genetic diversity, gene flow, mating patterns and early progeny vigor in the tropical dioecious tree, Brosimum alicastrum. We conducted our study in three continuous and three fragmented forest sites in a Mexican...

Data from: Not everything is black and white: color and behavioral variation reveal a continuum between cryptic and aposematic strategies in a polymorphic poison frog

Beatriz Willink, Esteban Brenes-Mora, Federico Bolaños & Heike Pröhl
Aposematism and crypsis are often viewed as two extremes of a continuum of visual conspicuousness to predators. Theory predicts that behavioral and coloration conspicuousness should vary in tandem along the conspicuousness spectrum for antipredator strategies to be effective. Here we used visual modeling of contrast and behavioral observations to examine the conspicuousness of four populations of the granular poison frog, Oophaga granulifera, which exhibits almost continuous variation in dorsal color. The patterns of geographic variation...

Data from: Temperature drives pre-reproductive selection and shapes the biogeography of a female polymorphism

Erik I. Svensson, Beatriz Willink, M. Catherine Duryea & Lesley Lancaster
Conflicts of interests between males and females over reproduction is a universal feature of sexually reproducing organisms and has driven the evolution of intersexual mimicry, mating behaviors and reproductive polymorphisms. Here we show how temperature drives pre-reproductive selection in a female colour polymorphic insect that is subject to strong sexual conflict. This species has three female colour morphs, one of which is a male mimic. This polymorphism is maintained by frequency-dependent sexual conflict caused by...
