Roubik, Henri-Pierre Aberlenc, Johannes Bail, Héctor Barrios, Jonathan R. Bridle, Gabriela Castaño-Meneses, Bruno Corbara, Gianfranco Curletti, Wesley Duarte Da Rocha, Domir De Bakker, Jacques H.C. Delabie, Alain Dejean, Laura L. Fagan, Andreas Floren, Roger L. Kitching … & Jacques H. C. Delabie
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...

Lourens Poorter, Frans Bongers, T. Mitchell Aide, Angélica M. Almeyda Zambrano, Patricia Balvanera, Justin M. Becknell, Vanessa Boukili, Pedro H. S. Brancalion, Eben N. Broadbent, Robin L. Chazdon, Dylan Craven, Jarcilene S. De Almeida-Cortez, George A. L. Cabral, Ben H. J. De Jong, Julie S. Denslow, Daisy H. Dent, Saara J. DeWalt, Juan M. Dupuy, Sandra M. Durán, Mario M. Espírito-Santo, María C. Fandino, Ricardo G. César, Jefferson S. Hall, José Luis Hernandez-Stefanoni, Catarina C. Jakovac … & Danaë M. A. Rozendaal
Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle1. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use2, 3, 4. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major...

Data from: A new platychelyid turtle (Pan-Pleurodira) from the Late Jurassic (Kimmeridgian) of Oaxaca, México

Oliver Ariel López-Conde, Juliana Sterli, Jesús Alvarado-Ortega & María Luisa Chavarría-Arellano
Until recently, the record of Mesozoic turtles in Mexico has been restricted to the Cretaceous. New discoveries in the Sabinal Formation (Tlaxiaco, Oaxaca) have extended the record into the Kimmeridgian (Late Jurassic). The Sabinal Formation is part of the Tlaxiaco Basin, which was a depocenter of continental and marine sediments dominated by transgressive-regressive marine conditions during the Jurassic–Cretaceous. The new turtle described here consists of an almost complete carapace associated with a plastron. Based on...

Data from: Competition and facilitation determine dwarf mistletoe infection dynamics

Mónica E. Queijeiro-Bolaños, Edgar Javier González, Carlos Martorell & Zenón Cano-Santana
1. Interspecific interactions have a fundamental role in plant population dynamics, as they may set the conditions for species coexistence. Parasitic plants, like dwarf mistletoes, offer the opportunity to study competition for resources that are different from those consumed by most plants, allowing for a better understanding of the interaction. 2. We explored how interspecific interactions between two dwarf mistletoe species (Arceuthobium), co-infecting the same host species (even sharing the same individual tree of Pinus...

Data from: Identifying management actions to increase foraging opportunities for shorebirds at semi-intensive shrimp farms

Juan G. Navedo, Guillermo Fernández, Nelson Valdivia, Mark C. Drever & Jose A. Masero
The expansion of aquaculture has resulted in widespread habitat conversion throughout the world. Identifying beneficial management measures may dramatically reduce negative impacts of aquaculture for migratory birds. We studied how densities of foraging shorebirds varied at ponds within a semi-intensive shrimp aquaculture farm on the north-western coast of Mexico, as related to timing of harvest and tidal cycles. Further, we estimated the total daily available area for each shorebird species throughout two entire harvesting seasons...

Data from: Columnar cacti as sources of energy and protein for frugivorous bats in a semi-arid ecosystem

L. Gerardo Herrera M. & Teresa López R.
Columnar cacti constitute the dominant elements in the vegetation structure of arid and semi-arid New World ecosystems representing a plethora of food resources for vertebrate consumers. Previous stable isotope analysis in Central Mexico showed that columnar cacti are of low importance to build tissue for frugivorous bats. We used carbon stable isotope analysis of whole blood and breath samples collected from four species of frugivorous bats (Sturnira parvidens, Sturnira ludovici, Artibeus jamaicensis, and Artibeus intermedius)...

Data from: The impact of reconstruction methods, phylogenetic uncertainty and branch lengths on inference of chromosome number evolution in American daisies (Melampodium, Asteraceae)

Jamie McCann, Gerald M. Schneeweiss, Tod F. Stuessy, Jose L. Villaseñor & Hanna Weiss-Schneeweiss
Chromosome number change (polyploidy and dysploidy) plays an important role in plant diversification and speciation. Investigating chromosome number evolution commonly entails ancestral state reconstruction performed within a phylogenetic framework, which is, however, prone to uncertainty, whose effects on evolutionary inferences are insufficiently understood. Using the chromosomally diverse plant genus Melampodium (Asteraceae) as model group, we assess the impact of reconstruction method (maximum parsimony, maximum likelihood, Bayesian methods), branch length model (phylograms versus chronograms) and phylogenetic...

Data from: Global analysis reveals that cryptic diversity is linked with habitat but not mode of life

Robert Poulin & Gerardo Perez-Ponce De Leon
The ubiquity of genetically distinct, cryptic species is limiting any attempt to estimate local or global biodiversity as well as impeding efforts to conserve species or control pests and diseases. Environmental factors or biological traits promoting rapid diversification into morphologically similar species remain unclear. Here, using a meta-analysis of 1230 studies using DNA sequences to search for cryptic diversity in metazoan taxa, we test two hypotheses regarding the frequency of cryptic taxa based on mode...

Data from: Seed to seedling transitions in successional habitats across a tropical landscape

Marinés De La Peña-Domene, Henry F. Howe, Emiliano Cruz-León, Rita Jiménez-Rolland, Cesar Lozano-Huerta & Cristina Martínez-Garza
Recognition that tree recruitment depends on the balance between seed arrival and seedling survival has led to a surge of interest in seed-dispersal limitation and seedling-establishment limitation in primary forests. Virtually unaddressed are comparisons of this balance in mature and early successional habitats. We assessed seed rain and seedling recruitment dynamics of tree species in primary forest, secondary forest and pasture released from grazing in a tropical agricultural landscape. Seed to seedling ratios (seed effectiveness;...

Data from: Tick infestation of chicks in a seabird colony varies with local breeding synchrony, local nest density and habitat structure

Alejandra G. Ramos & Hugh Drummond
Parasites are a major risk for group-living animals and seabirds are notoriously susceptible to ectoparasite infestations because they commonly nest in dense colonies. Ticks parasitize seabirds across all biogeographical regions and they can be particularly harmful to nestlings, but the ecological factors that affect their transmission to chicks are little studied and poorly understood. Here we show that abundance of tick larvae in blue-footed booby (Sula nebouxii) broods varies with local nest synchrony and density,...

Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global study

Luz Boyero, Richard Pearson, Cang Hui, Mark Gessner, Javier Perez, Markos Alexandrou, Manuel Graça, Bradley Cardinale, Ricardo Albariño, M. Arunachalam, Leon Barmuta, Andrew Boulton, Andreas Bruder, Marcos Callisto, Eric Chauvet, Russell Death, David Dudgeon, Andrea Encalada, Veronica Ferreira, Ricardo Figueroa, Alex Flecker, , Julie Helson, Tomoya Iwata, Tajang Jinggut … & Catherine Yule
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of different drivers of plant litter breakdown in fresh waters, particularly at large scales. We present a global-scale study of litter breakdown in streams to compare the roles of biotic, climatic and...

Data from: EDAPHOLOG monitoring system: automatic, real-time detection of soil microarthropods

Miklós Dombos, Oxána Bánszegi, Katalin Szlávecz & Andrés Kosztolányi
Soil microarthropods as organic matter decomposers play an important role in soil functioning thus providing ecosystem services. However, ecosystem scale investigations on their abundance and dynamics are scarce because their high spatio-temporal heterogeneity requires huge sample size. Processing and identifying large number of individuals are extremely labour-intensive. We prototyped a device called EDAPHOLOG monitoring system that consists of (1) a probe that catches and detects microarthropods and estimates their body size; (2) a data logger...

Data from: Sweat bees on hot chillies: provision of pollination services by native bees in traditional slash-and-burn agriculture in the Yucatán Peninsula of tropical Mexico

Patricia Landaverde-González, José Javier G. Quezada-Euán, Panagiotis Theodorou, Tomás E. Murray, Martin Husemann, Ricardo Ayala, Humberto Moo-Valle, Rémy Vandame & Robert J. Paxton
Traditional tropical agriculture often entails a form of slash-and-burn land management that may adversely affect ecosystem services such as pollination, which are required for successful crop yields. The Yucatán Peninsula of Mexico has a >4000 year history of traditional slash-and-burn agriculture, termed ‘milpa’. Hot ‘Habanero’ chilli is a major pollinator-dependent crop that nowadays is often grown in monoculture within the milpa system. We studied 37 local farmers’ chilli fields (sites) to evaluate the effects of...

Data from: Demography of Euterpe precatoria and Mauritia flexuosa in the Amazon: application of integral projection models for their harvest

Carolina Isaza, Rodrigo Bernal, Galeano. Gloria, Carlos Martorell & Gloria Galeano
Non-Timber Forest Products like palm fruits are fundamental in the livelihood of Amerindian groups. For the last 10 years the fruits of wild palm species, like Euterpe precatoria and Mauritia flexuosa, have been entering into global markets. These species are mostly harvested felling the adults, a practice that may have a disproportionate impact in the conservation of the populations. We studied the demography of E. precatoria and M. flexuosa, two important palms of the Amazon,...

Data from: Timing of rapid diversification and convergent origins of active pollination within Agavoideae (Asparagaceae)

Michael R. McKain, Joel R. McNeal, P. Roxanne Kellar, Luis E. Eguiarte, J. Chris Pires, James Leebens-Mack & Jim Leebens-Mack
PREMISE OF THE STUDY: Yucca species are ideal candidates for the study of coevolution due to the obligate mutualism they form with yucca moth pollinators (genera Tegeticula and Parategeticula). Yuccas are not the only species to exhibit a mutualism with yucca moths; the genus Hesperoyucca is pollinated by the California yucca moth (Tegeticula maculata). Relationships among yuccas, Hesperoyucca, and other members of subfamily Agavoideae are necessary to understand the evolution of this unique pollination syndrome....

Data from: Size distribution of function-based human gene sets and the split-merge model

Wentian Li, Oscar Fontanelli & Pedro Miramontes
The sizes of paralogues—gene families produced by ancestral duplication—are known to follow a power-law distribution. We examine the size distribution of gene sets or gene families where genes are grouped by a similar function or share a common property. The size distribution of Human Gene Nomenclature Committee (HGNC) gene sets deviate from the power-law, and can be fitted much better by a beta rank function. We propose a simple mechanism to break a power-law size...

Data from: Larger brain size indirectly increases vulnerability to extinction in mammals

Alejandro Gonzalez-Voyer, Manuela González-Suárez, Carles Vilà & Eloy Revilla
Although previous studies have addressed the question of why large brains evolved, we have limited understanding of potential beneficial or detrimental effects of enlarged brain size in the face of current threats. Using novel phylogenetic path analysis, we evaluated how brain size directly and indirectly, via its effects on life-history and ecology, influences vulnerability to extinction across 474 mammalian species. We found that larger brains, controlling for body size, indirectly increase vulnerability to extinction by...

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: Reproductive ecology and isolation of Psittacanthus calyculatus and P. auriculatus mistletoes (Loranthaceae)

Sergio Díaz Infante, Carlos Lara, María Del Coro Arizmendi, Luis E. Eguiarte & Juan Francisco Ornelas
Background: Relationships between floral biology and pollinator behavior are important to understanding species diversity of hemiparasitic Psittacanthus mistletoes (c. 120 species). We aimed to investigate trait divergence linked to pollinator attraction and reproductive isolation (RI) in two hummingbird-pollinated and bird-dispersed Psittacanthus species with range overlap. Methods: We investigated the phylogenetic relationships, floral biology, pollinator assemblages, seed dispersers and host usage, and the breeding system and female reproductive success of two sympatric populations of P. calyculatus...

Data from: Precipitation mediates the effect of human disturbance on the Brazilian Caatinga vegetation

Kátia F. Rito, Víctor Arroyo-Rodríguez, Rubens T. De Queiroz, Inara R. Leal & Marcelo Tabarelli
Seasonally dry tropical forests (SDTFs) are one of the most threatened forests worldwide. These species-rich forests not only cope with several acute (e.g. forest loss) and chronic (e.g. overgrazing and firewood extraction) human disturbances, but also with climate change (e.g. longer and more severe droughts); yet, the isolated and combined effects of climate and acute and chronic human disturbances on SDTF vegetation are poorly known. Given the environmental filter imposed by drought in SDTFs, the...

Data from: Independent origins of resistance or susceptibility of parasitic wasps to a defensive symbiont

Mariana Mateos, Lauryn Winter, Caitlyn Winter, Victor M. Higareda-Alvear, Esperanza Martinez-Romero & Jialei Xie
Insect microbe associations are diverse, widespread, and influential. Among the fitness effects of microbes on their hosts, defense against natural enemies is increasingly recognized as ubiquitous, particularly among those associations involving heritable, yet facultative, bacteria. Protective mutualisms generate complex ecological and co-evolutionary dynamics that are only beginning to be elucidated. These depend in part on the degree to which symbiont-mediated protection exhibits specificity to one or more members of the natural enemy community. Recent findings...

Data from: Oxidative stress during courtship affects male and female reproductive effort differentially in a wild bird with biparental care

Bibiana Montoya, Mahara Valverde, Emilio Rojas & Roxana Torres
Oxidative stress has been suggested as one of the physiological mechanisms modulating reproductive effort, including investment in mate choice. Here, we evaluated whether oxidative stress influences breeding decisions by acting as a cost of or constraint on reproduction in the brown booby (Sula leucogaster), a long-lived seabird with prolonged biparental care. We found that during courtship, levels of lipid peroxidation (LP) of males and females were positively associated with gular skin color, a trait presumably...

Data from: Genetic and morphological evidence of a geographically widespread hybrid zone between two crocodile species, Crocodylus acutus and Crocodylus moreletii

Gualberto Pacheco-Sierra, Zachariah Gompert, Jerónimo Domínguez-Laso & Ella Vázquez-Domínguez
Hybrid zones represent natural laboratories to study gene flow, divergence and the nature of species boundaries between closely related taxa. We evaluated the level and extent of hybridization between Crocodylus moreletii and C. acutus using genetic and morphological data on 300 crocodiles from 65 localities. To our knowledge, this is the first genetic study that includes the entire historic range and sympatric zone of the two species. Contrary to expectations, Bayesian admixture proportions and maximum...

Data from: No evidence that genetic compatibility drives extra-pair behavior in female blue-footed boobies

Lynna Marie Kiere, Alejandra G. Ramos & Hugh Drummond
The function of female birds' extra-pair (EP) behavior has remained an unresolved question in ornithology and behavioral ecology for > 30 yr. The genetic compatibility hypothesis (GCH) proposes that females benefit by acquiring biological sires that yield more heterozygous, and therefore fitter, offspring than their social mates. We used ten polymorphic microsatellite loci to test GCH predictions and its assumption that fitness increases with heterozygosity in blue-footed boobies Sula nebouxii, a long-lived tropical seabird. Our...

Data from: The activity of dung beetles increases foliar nutrient concentration in tropical seedlings

Carolina Santos-Heredia, Ellen Andresen, Ek Del-Val, Diego A. Zárate, Maribel Nava Mendoza & Víctor J. Jaramillo
Dung beetles are extensively used as a focal taxon in tropical forests. Yet, information for most of their ecological functions comes from other systems. We present results from a field experiment in a tropical rainforest showing that dung beetle activity increases foliar phosphorus concentration in seedlings of the tree Brosimum lactescens. Our results open new lines of research to assess the multiple effects that dung beetles may have on rainforest plants.
