Genetic structuring in a Neotropical palm analyzed through an Andean orogenesis‐scenario
Sebastián Escobar, Jean‐Christophe Pintaud, Henrik Balslev, Rodrigo Bernal, Mónica Moraes Ramírez, Betty Millán & Rommel Montúfar
Andean orogenesis has driven the development of very high plant diversity in the Neotropics through its impact on landscape evolution and climate. The analysis of the intraspecific patterns of genetic structure in plants would permit inferring the effects of Andean uplift on the evolution and diversification of Neotropical flora. In this study, using microsatellite markers and Bayesian clustering analyses, we report the presence of four genetic clusters for the palm Oenocarpus bataua var. bataua which...

• 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...
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...
Data from: Temperature and vegetation complexity structure mixed-species flocks along a gradient of elevation in the tropical Andes
Flavia A. Montaño-Centellas & Harrison Jones
Mixed-species flocks constitute community modules that can help test mechanisms driving changes to community composition across environmental gradients. Here, we examined elevational patterns of flock diversity (species richness, taxonomic diversity, species and guild composition) and asked if these patterns were reflections of the full bird community at a given elevation (open-membership hypothesis), or if they were instead structured by environmental variables. We surveyed both the overall avian community and mixed-species flocks across an undisturbed elevational...
Data from: Multiple dimensions of bird beta diversity support that mountains are higher in the tropics
Flavia A. Montaño-Centellas, Bette Loiselle & Christy McCain
Aim We examine latitudinal effects of breeding bird taxonomic, phylogenetic and functional β-diversity (Tβ, Pβ and Fβ, respectively) along elevational gradients to test predictions derived from Janzen’s (1967) classic ideas that tropical mountains represent stronger dispersal barriers than temperate mountains. Location Global Taxon Birds Methods Using a global dataset from 46 mountains, we examine latitudinal patterns of Tβ, Pβ, and Fβ, and their components: β rich and β repl. For each mountain and each dimension...
The behavioral responses of the Chiguanco thrush to urbanization in a Neotropical city comes from preadapted behavioral traits
Alvaro Garitano-Zavala, Rodrigo Calbimonte & Guillermo Esteve-Herraiz
Several animal species can survive within cities by changing their behavior; such changes could be the result of evolutionary adaptation, epigenetic effects, or come from preadapted traits through phenotypic plasticity or non-random dispersal. Exploring whether behavioral preadapted traits are present in non-urbanized populations could improve our understanding of the processes that allow animals to cope with urbanization. We compared the boldness, neophobia, and solving-test skills of adult individuals of the Chiguanco Thrush (Turdus chiguanco) between...
Predator and destructor species of artificial bird nests in La Paz, Bolivia
Álvaro Garitano-Zavala & Andrea Salazar-Pammo
Urbanization alters the composition of biological communities and, therefore, ecological processes such as predation and destruction of bird nests. The identification of predator and destructor species is useful for designing research for the understanding of the effects of urbanization on these ecological processes. In this study, we identify the diurnal predator and destructor species of artificial bird nests in urban and peri-urban sites of the metropolitan region of La Paz, Bolivia, using webcams. The House...
ANDEAN frugivory: data on plant–bird interactions and functional traits of plant and bird species from montane forests along the Andes
D. Matthias Dehling, Irene M. A. Bender, Pedro G. Blendinger, Marcia C. Muñoz, Marta Quitián, Francisco Saavedra, Vinicio Santillán, Katrin Böhning-Gaese, Eike-Lena Neuschulz & Matthias Schleuning
Species differ in their resource use and their interactions with other species and, consequently, they fulfil different functional roles in ecological processes. Species with specialized functional roles (specialists) are considered important for communities because they often interact with species with which few other species interact, thereby contributing complementary functional roles to ecological processes. However, the contribution of specialists could be low if they only interact with a small range of interaction partners. In contrast, species...
Dataset: Local hydrological conditions influence tree diversity and composition across the Amazon basin

Sousa, Juliana Schietti, Luiz De Souza Coelho, José Ferreira Ramos, Diogenes De Andrade Lima Filho, Iêda Leão Amaral, Francisca Dionízia De Almeida Matos, Lorena M.

Salomão, Leandro Valle Ferreira, Dário Dantas Do Amaral, Nigel C.A. Pitman, Corine Vriesendorp, Tim R. Baker, Roel Brienen, Marcelo De Jesus Veiga Carim … & Flávia R.C. Costa
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well-drained and potentially dry areas. While these conditions may be expected to influence species distribution, the impacts of local hydrological conditions on tree diversity and composition remain...
Data and code: Global and regional ecological boundaries explain abrupt spatial discontinuities in avian frugivory interactions

Donatti, Carine Emer, Mauro Galetti, Ruben Heleno, Pedro Jordano, Ícaro Menezes, José Carlos Morante-Filho, Marcia C. Muñoz, Eike Lena Neuschulz, Marco Aurélio Pizo, Marta Quitián, Roman A. Ruggera, Francisco Saavedra, Vinicio Santillán, Virginia Sanz D’Angelo, Matthias Schleuning, Luís Pascoal Da Silva … & Jason M. Tylianakis
Species interactions can propagate disturbances across space via direct and indirect effects, potentially connecting species at a global scale. However, ecological and biogeographic boundaries may mitigate this spread by demarcating the limits of ecological networks. We tested whether large-scale ecological boundaries (ecoregions and biomes) and human disturbance gradients increase dissimilarity among plant-frugivore networks, while accounting for background spatial and elevational gradients and differences in network sampling. We assessed network dissimilarity patterns over a broad spatial...
Data for: Environmental gradualism explains variation in pollination systems of columnar cacti: Phylogenetic and trait evolution analyses
Damián Freilij, Daniel Larrea Alcazar, Ramiro Pablo Lopez, Fernando Velarde Simonini, Kazuya Naoki & Cecilia Bessega
Aim: The Geographic Dichotomy Hypothesis (GDH) states several flowering plant groups have specialized pollination systems in tropical areas, where resources are more reliable and pollinator communities tend to be more stable. Our main goal was to understand the scope of the GDH and/or gradual environmental variation considering the evolutionary history of the pollination traits. Location: Neotropical tropics and adjacent extra-tropics. Major taxa studied: Columnar cacti. Methods: Using a database composed of ~54 columnar cacti species...
