Data from: Comparative phylogeography of trans-Andean freshwater fishes based on genome-wide nuclear and mitochondrial markers

Melissa Rincon-Sandoval, Ricardo Betancur-R & Javier A. Maldonado-Ocampo
The Neotropical region represents one of the greatest biodiversity hotspots on earth. Despite its unparalleled biodiversity, regional comparative phylogeographic studies are still scarce, with most focusing on model clades (e.g., birds) and typically examining a handful of loci. Here, we apply a genome-wide comparative phylogeographic approach to test hypotheses of co-diversification of freshwater fishes in the trans-Andean region. Using target capture methods, we examined exon data for over 1,000 loci combined with complete mitochondrial genomes...

This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography. Aim. Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help...

Data from: Seasonal cycles, phylogenetic assembly, and functional diversity of orchid bee communities

Santiago R. Ramírez, Carlos Hernández, Andres Link & Margarita M. López-Uribe
Neotropical rainforests sustain some of the most diverse terrestrial communities on Earth. Euglossine (or orchid) bees are a diverse lineage of insect pollinators distributed throughout the American tropics, where they provide pollination services to a staggering diversity of flowering plant taxa. Elucidating the seasonal patterns of phylogenetic assembly and functional trait diversity of bee communities can shed new light into the mechanisms that govern the assembly of bee pollinator communities and the potential effects of...

Data from: Eating down the food chain: generalism is not an evolutionary dead end for herbivores

Danny Rojas, Maria João Ramos Pereira, Carlos Fonseca & Liliana M. Dávalos
The role of trophic specialisation in taxonomic diversification remains unclear. Plant specialists diversify faster than omnivores and animalivores, but at shorter macroevolutionary scales this pattern sometimes reverses. Here, we estimate the effect of diet diversification on speciation rates in noctilionoid bats, controlling for tree shape, rate heterogeneity and macroevolutionary regimes. We hypothesise that niche subdivision among herbivores positively relates to speciation rates, differing between macroevolutionary regimes. We found the rate at which new herbivorous lineages...

Data from: Impact of a hurricane on the herpetofaunal assemblages of a successional chronosequence in a tropical dry forest

Ireri Suazo-Ortuño, José Nicolás Urbina-Cardona, Nancy Lara-Uribe, Jorge Marroquín-Páramo, Yunuen Soto-Sandoval, Jorge Rangel-Orozco, Leonel Lopez-Toledo, Julieta Benítez-Malvido & Javier Alvarado-Díaz
Land‐use change is the main cause of deforestation and degradation of tropical forest in Mexico. Frequently, these lands are abandoned leading to a mosaic of natural vegetation in secondary succession. Further degradation of the natural vegetation in these lands could be exacerbated by stochastic catastrophic events such as hurricanes. Information on the impact of human disturbance parallel to natural disturbance has not yet been evaluated for faunal assemblages in tropical dry forests. To evaluate the...

Data from: Species sorting and mass effect along forest succession: evidence from taxonomic, functional, and phylogenetic diversity of amphibian communities

Omar Hernández-Ordóñez, Braulio A. Santos, Robert Alexander Pyron, Victor Arroyo-Rodriguez, J. Nicolás Urbina-Cardona, Miguel Martínez-Ramos, Gabriela Parra-Olea & Victor Hugo Reynoso
Species recovery after forest disturbance is a highly studied topic in the tropics, but considerable debate remains on the role of secondary forests as biodiversity repositories, especially regarding the functional and phylogenetic dimensions of biodiversity. Also, studies generally overlook how alpha and beta diversities interact to produce gamma diversity along successional gradients. We used a metacommunity approach to assess how species sorting (i.e., environmental filtering) and mass effect (i.e., source‐sink dynamics) affect 14 complementary metrics...

Data from: The dynamics of tent-roosts in the palm Sabal mauritiiformis and their use by bats in a montane dry forest

Ana María Herrera-Victoria, Marlyn Zuluaga-Egas, Vladimir Rojas-Díaz, Leonor A. Valenzuela & Gustavo H. Kattan
Tent-making bats modify leaves to build refuges. Leaf modification involves energetic and defense costs that should be balanced by the benefits of tent-roosting. The alteration of the leaf’s vascular system reduces the tent’s life expectancy, so to obtain a benefit bats are expected to use tents regularly as long as they are functional and not modify more leaves than necessary. Over two years we documented the dynamics of tent construction and use by Uroderma convexum...

Data and code for: Parthenogenesis is self-destructive for scaled reptiles

Matthew Moreira, Danny Rojas & Carlos Fonseca
Parthenogenesis is rare in nature. With 39 described true parthenogens, scaled reptiles (Squamata) are the only vertebrates that evolved this reproductive strategy. Parthenogenesis is ecologically advantageous in the short-term, but the young age and rarity of parthenogenetic species indicate it is less advantageous in the long-term. This suggests parthenogenesis is self-destructive: it arises often but is lost due to increased extinction rates, high rates of reversal or both. However, this role of parthenogenesis as a...

Data from: Functional diversity of phyllostomid bats in an urban-rural landscape: a scale-dependent analysis

Andrés F. Ramírez-Mejía, J. Nicolás Urbina-Cardona & Francisco Sánchez
Urbanization is one of the most pervasive landscape transformational processes responsible for novel selection agents promoting functional community homogenization. Bats may persist in those human environments, but the mechanisms responsible for their adaptability and the spatial scales in which landscape imposes environmental filtering remain poorly studied in the Neotropics. We tested the hypothesis that landscape composition interacts with the spatial scale to affect the functional diversity of phyllostomids in an urban-rural gradient. Based on functional...

Impacts of pastures and forestry plantations on herpetofauna: a global meta-analysis

Pablo A. López-Bedoya, Erika Alejandra Cardona-Galvis, J. Nicolás Urbina-Cardona, Felicity A. Edwards & David P. Edwards
1. The establishment of pastures and forestry plantations has increased globally to meet growing demands for meat and wood products. Pasture and plantation expansion often drives deforestation, which causes homogenization of biotic communities and is a major driver of the global extinction crisis. A core question is how the severity of losses varies between pastures and plantations, and in turn, how geographical location and plantation management characteristics moderate these impacts. 2. Focusing on herpetofauna (amphibians...

Data from: Conservation genetics of the scalloped hammerhead shark in the Pacific coast of Colombia

Sonia Quintanilla, Alberto Gomez, Camila Mariño-Ramírez, Carolina Sorzano, Sandra Bessudo, German Soler, Jaime E. Bernal & Susana Caballero
Previous investigations of the population genetics of the scalloped hammerhead sharks (Sphyrna lewini) in the Eastern Tropical Pacific have lacked information about nursery areas. Such areas are key to promoting conservation initiatives that can protect young sharks from threats such as overfishing. Here, we investigated the genetic diversity, phylogeography, and connectivity of S. lewini found in 3 areas of Colombia’s Pacific coast: around Malpelo Island and in 2 National Natural Parks on the Colombian Pacific...

Data from: Latitudinal and altitudinal patterns of plant community diversity on mountain summits across the tropical Andes

Francisco Cuesta, Priscilla Muriel, Luis D. Llambí, Stephan Halloy, Nikolay Aguirre, Stephan Beck, Julieta Carilla, Rosa I. Meneses, Soledad Cuello, Alfredo Grau, Luis E. Gámez, Javier Irazábal, Jorge Jacome, Ricardo Jaramillo, Lirey Ramírez, Natalia Samaniego, David Suárez-Duque, Natali Thompson, Alfredo Tupayachi, Paul Viñas, Karina Yager, María T. Becerra, Harald Pauli & William D. Gosling
The high tropical Andes host one of the richest alpine floras of the world, with exceptionally high levels of endemism and turnover rates. Yet, little is known about the patterns and processes that structure altitudinal and latitudinal variation in plant community diversity. Herein we present the first continental-scale comparative study of plant community diversity on summits of the tropical Andes. Data were obtained from 792 permanent vegetation plots (1m2) within 50 summits, distributed along a...

Plant dispersal strategies of high tropical alpine communities across the Andes

Carolina Tovar, Inga Melcher, Buntarou Kusumoto, Francisco Cuesta, Antoine Cleef, Rosa Isela Meneses, Stephan Halloy, Luis Daniel Llambi, Stephan Beck, Priscilla Muriel, Ricardo Jaramillo, Jorge Jacome & Julieta Carilla
• Dispersal is a key ecological process that influences plant community assembly. Therefore, understanding whether dispersal strategies are associated with climate is of utmost importance, particularly in areas greatly exposed to climate change. We examined alpine plant communities located in the mountain summits of the tropical Andes across a 4000 km latitudinal gradient. We investigated species dispersal strategies and tested their association with climatic conditions and their evolutionary history. • We used dispersal-related traits (dispersal...

Support for the habitat amount hypothesis from a global synthesis of species density studies

James Watling, Víctor Arroyo-Rodríguez, Marion Pfeifer, Lander Baeten, Cristina Banks-Leite, Laura Cisneros, Rebecca Fang, Caroli Hamel-Leigue, Thibault Lachat, Inara Leal, Luc Lens, Hugh Possingham, Dinarzarde Raheem, Danilo Ribeiro, Eleanor Slade, Nicolas Urbina-Cardona, Eric Wood & Lenore Fahrig
Decades of research suggest that species richness depends on spatial characteristics of habitat patches, especially their size and isolation. In contrast, the habitat amount hypothesis predicts that: 1) species richness in plots of fixed size (species density) is more strongly and positively related to the amount of habitat around the plot than to patch size or isolation; 2) habitat amount better predicts species density than patch size and isolation combined, 3) there is no effect...

Data from: Accelerated diversification explains the exceptional species richness of tropical characoid fishes

Bruno Melo, Brian Sidlauskas, Thomas Near, Fabio Roxo, Ava Ghezelayagh, Luz Ochoa, Melanie Stiassny, Jairo Arroyave, Jonathan Chang, Brant Faircloth, Daniel MacGuigan, Richard Harrington, Ricardo Benine, Michael Burns, Kendra Hoekzema, Natalia Sanches, Javier Maldonado-Ocampo, Ricardo Castro, Fausto Foresti, Michael Alfaro & Claudio Oliveira
The Neotropics harbor the most species-rich freshwater fish fauna on the planet, but the timing of that exceptional diversification remains unclear. Did the Neotropics accumulate species steadily throughout their long history, or attain their remarkable diversity recently? Biologists have long debated the relative support for these museum and cradle hypotheses, but few phylogenies of megadiverse tropical clades have included sufficient taxa to distinguish between them. We used 1288 ultraconserved element loci spanning 293 species, 211...
