Data from: Limited genetic evidence for host plant-related differentiation in the Western cherry fruit fly Rhagoletis indifferens (Diptera: Tephritidae)Gilbert Saint Jean, Glen R. Hood, Scott P. Egan, Thomas H.Q. Powell, Hannes Schuler, Meredith M. Doellman, Mary M. Glover, James J. Smith, Wee L. Yee, Robert B. Goughnour, Howard M.A. Thistlewood, Sheri A.

The shift of the fruit fly Rhagoletis pomonella (Walsh) in the mid-1800s from downy hawthorn, Crataegus mollis (Torrey & Asa Gray) Scheele, to introduced domesticated apple, Malus domestica (Borkhausen), in the eastern USA is a model for ecological divergence with gene flow. A similar system may exist in the northwestern USA and British Columbia, Canada, where Rhagoletis indifferens Curran (Diptera: Tephritidae) attacks the native bitter cherry Prunus emarginata (Douglas ex Hooker) Eaton (Rosaceae). Populations of...
1. The interaction between the nurse plant Larrea tridentata and the cacti Cylindropuntia leptocaulis is thought to follow cyclical-replacement dynamics. However, the required changing nature of their interaction, from facilitation to competition, has not been investigated through their full life cycle. 2. In order to test the hypothesised cyclical dynamics, we compared the demography of four sub-populations (LA = Larrea associated to Cylindropuntia; CA = Cylindropuntia associated to Larrea, LS = solitary Larrea; CS =...
Data from: Coordinated species importation policies are needed to reduce serious invasions globally: the case of alien bumblebees in South AmericaMarcelo A. Aizen, Cecilia Smith-Ramirez, Carolina L. Morales, Lorena Vieli, Agustín Sáez, Rodrigo M. Barahona-Segovia, Marina P. Arbetman, José Montalva, Lucas A. Garibaldi, David W. Inouye & Lawrence D. Harder
The global trade of species promotes diverse human activities but also facilitates the introduction of potentially invasive species into new environments. As species ignore national boundaries, unilateral national decisions concerning species trade set the stage for transnational species invasion with significant conservation, economic and political consequences. The need for a coordinated approach to species importation policies is demonstrated by the introduction of two bumblebee species into Chile for crop pollination, despite Argentina banning commercial importation...
Data from: A dark scenario for Cerrado plant species: effects of future climate, land use and protected areas ineffectivenessSantiago José Elías Velazco, Fabricio Villalobos, Franklin Galvão & Paulo De Marco Júnior
Aim: The anthropogenic climate change and land-use change are considered two of the main factors that are altering biodiversity at the global scale. An evaluation that combined both factors can be relevant to detect which species could be the most vulnerable and reveal the regions of highest stability or susceptibility to biodiversity. We aimed to (i) assess the effect of climate change and land-use on the distribution of Cerrado plant species for different countries where...
Data from: Pleistocene range expansions promote divergence with gene flow between migratory and sedentary populations of Calothorax hummingbirdsYuyini Licona-Vera, Juan Francisco Ornelas, Susan Wethington & Kelly B. Bryan
We investigate the influence of postglacial population expansion on genetic structure of reproductively isolated populations that come into secondary contact and produce hybrid zones. We test migratory behaviour to explain geographic patterns of genetic diversity and phylogeographic structure in migratory and sedentary populations of hummingbirds in the Chihuahuan Desert. We assessed genetic structure, demographic expansion and introgression in Calothorax hummingbirds using mitochondrial DNA (mtDNA) and nuclear microsatellites (nSSRs), and ecological niche modelling (ENM) to predict...
Data from: Genetic structuring and secondary contact in the white-chested Amazilia hummingbird species complexFlor Rodríguez-Gómez & Juan F. Ornelas
Pleistocene climate cycles have been recognized to be a major driver of postglacial northward range expansion of North American bird populations. During glacial maxima, allopatric lineages that were reproductively isolated might have come into secondary contact with one another during expansion periods and the genetic signatures of past hybridization as a result of secondary contact events should produce detectable hybrid zones. The white-chested hummingbirds, Amazilia violiceps and A. viridifrons, constitute a species complex showing phenotypic...
Data from: Community composition and diversity of Neotropical root-associated fungi in common and rare treesJohn W. Schroeder, Jessica T. Martin, Diego F. Angulo, Jomar M. Barbosa, Ramón Perea, Itzel Arias-Del Razo, Esther Sebastián-González & Rodolfo Dirzo
Interactions between plants and root-associated fungi can affect the assembly, diversity, and relative abundances of tropical plant species. Host-symbiont compatibility and some degree of host specificity are prerequisites for these processes to occur, and these prerequisites may vary with host abundance. However, direct assessments of whether specificity of root-associated fungi varies with host abundance are lacking. Here, in a diverse tropical forest in Los Tuxtlas, Mexico, we couple DNA metabarcoding with a sampling design that...
Data from: Jaguar Movement Database: a GPS-based movement dataset of an apex predator in the NeotropicsRonaldo G. Morato, Jeffrey J. Thompson, Agustín Paviolo, J. Antonio De La Torre, Fernando Lima, , Rogério C. Paula, , Leandro Silveira, Daniel L.Z. Kantek, Emiliano E. Ramalho, Louise Maranhão, Mario Haberfeld, Denis A. Sana, Rodrigo A. Medellin, Eduardo Carrillo, Victor Montalvo, Octavio Monroy-Vilchis, Paula Cruz, Anah Tereza Jácomo, Natalia M. Torres, Giselle B. Alves, Ivonne Cassaigne, Ron Thompson, Carolina Saenz-Bolanos … & Joares A. May
The field of movement ecology has rapidly grown during the last decade, with important advancements in tracking devices and analytical tools that have provided unprecedented insights into where, when, and why species move across a landscape. Although there has been an increasing emphasis on making animal movement data publicly available, there has also been a conspicuous dearth in the availability of such data on large carnivores. Globally, large predators are of conservation concern. However, due...
Data from: Pollinator-mediated interactions between cultivated papaya and co-flowering plant speciesRaúl Badillo-Montana, Armando Aguirre & Miguel A. Munguía‐Rosas
Many modern crop varieties rely on animal pollination to set fruit and seeds. Intensive crop plantations usually do not provide suitable habitats for pollinators so crop yield may depend on the surrounding vegetation to maintain pollination services. However, little is known about the effect of pollinator-mediated interactions among co-flowering plants on crop yield or the underlying mechanisms. Plant reproductive success is complex, involving several pre- and post-pollination events; however, the current literature has mainly focused...
Mexico is considered an exceptional biogeographic area with a varied and unique endemic vascular flora that is estimated at half of the global total of approximately 24,500 species. However, spatial phylogenetic measures of biodiversity for this flora have not yet been estimated to understand how the Mexican flora assembled to form current vegetation. Patterns of species richness, weighted endemism, phylogenetic diversity and weighted phylogenetic endemism, as well as centers of neo- and paleo-endemism were determined...
Data from: Functional connectivity and home range inferred at a microgeographic landscape genetics scale in a desert-dwelling rodentAlejandro Flores-Manzanero, Madisson A. Luna- Bárcenas, Rodney J. Dyer & Ella Vázquez-Domínguez
Gene flow in animals is limited or facilitated by different features within the landscape matrix they inhabit. The landscape representation in landscape genetics (LG) is traditionally modeled as resistance surfaces (RS), where novel optimization approaches are needed for assigning resistance values that adequately avoid subjectivity. Also, desert ecosystems and mammals are scarcely represented in LG studies We addressed these issues by evaluating, at a microgeographic scale, the effect of landscape features on functional connectivity of...
Data from: A hyper arid environment shapes an inverse pattern of the fast–slow plant economics spectrum for above-, but not belowground resource acquisition strategiesDanny E. Carvajal, Andrea P. Loayza, Rodrigo S. Rios, Cristián A. Delpiano & Francisco A. Squeo
1. The fast–slow plant economics spectrum predicts that because of evolutionary and biophysical constraints, different plant organs must be coordinated to converge in a unique ecological strategy within a continuum that shifts from fast to slow resource acquisition and conservation. Therefore, along a gradient of aridity, taxa with different strategies will be expected to be successful because selection pressures for slow resource acquisition become stronger as the environment becomes drier. In extremely arid and seasonal...
Data from: Are pulp consumers effective seed dispersers? Tests with a large-seeded tropical relict treeMara Peña-Egaña, Andrea P. Loayza & Francisco A. Squeo
Several plant species in the Neotropics bear large, fleshy fruits that suggest adaptation to endozoochorous seed dispersal by large vertebrates. Many of these plants, however, occur in areas where large vertebrates are no longer present, consequently, their seeds are dispersed by pulp consumers; small vertebrates that only ingest the pulp reward because they are uncapable of swallowing the fruits whole. Few studies have examined the role of these pulp consumers on the regeneration of large-fruited/seeded...
