Data from: Cenozoic colonization and diversification patterns of tropical American palms: evidence from Astrocaryum (Arecaceae)

Julissa Roncal, Francis Kahn, Betty Millan, Thomas L. P. Couvreur & Jean-Christophe Pintaud
With 788 species in 67 genera in the Neotropics, Arecaceae are an important ecological and economic component of the region. We review the influence of geological events such as the Pebas system, the Andean uplift and the land connections between South and Central/North America, on the historical assembly of Neotropical palms. We present a case study of the palm genus Astrocaryum (40 species) as a model for evaluating colonization and diversification patterns of lowland Neotropical...

Data from: Cough frequency during treatment associated with baseline cavitary volume and proximity to the airway in pulmonary TB

Alvaro Proaño, David P. Bui, José W. López, Nancy M. Vu, Marjory A. Bravard, Gwenyth O. Lee, Brian H. Tracey, Ziyue Xu, Germán Comina, Eduardo Ticona, Daniel J. Mollura, Jon S. Friedland, David A. J. Moore, Carlton A. Evans, Philip Caligiuri, Robert H. Gilman & Tuberculosis Working Group In Peru
Background: Cough frequency, and its duration, is a lab-free biomarker that can be used in low-resource settings and has been associated with transmission and treatment response. Radiological characteristics associated with increased cough frequency may be important in understanding transmission. The relationship between cough frequency and cavitary lung disease has never been studied. Methods: We analyzed 41 human immunodeficiency virus-negative adults with culture-confirmed, drug-susceptible pulmonary tuberculosis throughout treatment. Cough recordings were based on the Cayetano Cough...

Data from: Mating patterns and post-mating isolation in three cryptic species of the Engystomops petersi species complex

Paula A. Trillo, Andrea E. Narvaez, Santiago R. Ron & Kim L. Hoke
Determining the extent of reproductive isolation in cryptic species with dynamic geographic ranges can give us important insights into the processes that generate and maintain genetic divergence in the absence of severe geographic barriers. We studied mating patterns, propensity to crossbreed in nature and subsequent fertilization rates, as well as survival and development of hybrid F1 offspring for three species of the E. petersi species complex in Yasuní National Park, Ecuador. We found at least...

Data from: Integrative taxonomy and preliminary assessment of species limits in the Liolaemus walkeri complex (Squamata, Liolaemidae) with descriptions of three new species from Peru

César Aguilar, Wood Jr, Perry L., Juan C. Cusi, Alfredo Guzmán, Frank Huari, Mikael Lundberg, Emma Mortensen, César Ramírez, Daniel Robles, Juana Suárez, Andres Ticona, Víctor J. Vargas, Pablo J. Venegas, Sites Jr, Jack W., Perry Wood & Jack Sites
Species delimitation studies based on integrative taxonomic approaches have received considerable attention in the last few years, and have provided the strongest hypotheses of species boundaries. We used three lines of evidence (molecular, morphological, and niche envelopes) to test for species boundaries in Peruvian populations of the Liolaemus walkeri complex. Our results show that different lines of evidence and analyses are congruent in different combinations, for unambiguous delimitation of three lineages that were “hidden” within...

High-resolution satellite-gauge merged precipitation climatologies of the tropical Andes

B. Manz, W. Buytaert, Z. Zulkafli, W. Lavado, B. Willems, A. Robles L. & J.-P. Rodríguez Sánchez
A set of 130 digital precipitation maps of the tropical Andes, covering Colombia, Ecuador and Peru at a 5km resolution. The maps represent different realizations of mean precipitation totals of the period 1981-2010 using different satellite-gauge merging methods. The work draws on a large database of 723 rain gauges and the full 5km Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (TPR) record from 1998 to 2014. Each map is approximately 1MB
