Data from: Co-feeding intra- and interspecific transmission of an emerging insect-borne rickettsial pathogen

Lisa D. Brown, Rebecca C. Christofferson, Kaikhushroo H. Banajee, Fabio Del Piero, Lane D. Foil & Kevin R. Macaluso
Cat fleas (Ctenocephalides felis) are known as the primary vector and reservoir of Rickettsia felis, the causative agent of flea-borne spotted fever; however, field surveys regularly report molecular detection of this infectious agent from other blood-feeding arthropods. The presence of R. felis in additional arthropods may be the result of chance consumption of an infectious bloodmeal, but isolation of viable rickettsiae circulating in the blood of suspected vertebrate reservoirs has not been demonstrated. Successful transmission...

Data from: Coordinated dispersal and pre-Isthmian assembly of the Central American ichthyofauna

Victor A. Tagliacollo, Scott M. Duke-Sylvester, Wilfredo A. Matamoros, Prosanta Chakrabarty & James S. Albert
We document patterns of coordinated dispersal over evolutionary time frames in heroine cichlids and poeciliine live-bearers, the two most species-rich clades of freshwater fishes in the Caribbean basin. Observed dispersal rate (DO) values were estimated from time-calibrated molecular phylogenies in Lagrange+, a modified version of the ML-based parametric biogeographic program Lagrange. DO is measured in units of ‘wallaces’ (wa) as the number of biogeographic range-expansion events per million years. DO estimates were generated on a...

Data from: Biological evidence supports an early and complex emergence of the Isthmus of Panama

Christine D. Bacon, Daniele Silvestro, Carlos Jaramillo, Brian Tilston Smith, Prosanta Chakrabarty & Alexandre Antonelli
The formation of the Isthmus of Panama, which linked North and South America, is key to understanding the biodiversity, oceanography, atmosphere, and climate in the region. Despite its importance across multiple disciplines, the timing of formation and emergence of the Isthmus and the biological patterns it created have been controversial. Here, we analyze molecular and fossil data, including terrestrial and marine organisms, to show that biotic migrations across the Isthmus of Panama began several million...

Data from: Whole genome sequencing of elite rice cultivars as a comprehensive information resource for marker assisted selection

Jorge Duitama, Alexander Silva, Yamid Sanabria, Daniel Felipe Cruz, Constanza Quintero, Carolina Ballen, Mathias Lorieux, Brian Scheffler, Andrew Farmer, Edgar Torres, James Oard & Joe Tohme
Current advances in sequencing technologies and bioinformatics revealed the genomic background of rice, a staple food for the poor people, and provided the basis to develop large genomic variation databases for thousands of cultivars. Proper analysis of this massive resource is expected to give novel insights into the structure, function, and evolution of the rice genome, and to aid the development of rice varieties through marker assisted selection or genomic selection. In this work we...

Data from: Sequence capture of ultraconserved elements from bird museum specimens

John E. McCormack, Whitney L. E. Tsai, Brant C. Faircloth & Whitney L.E. Tsai
New DNA sequencing technologies are allowing researchers to explore the genomes of the millions of natural history specimens collected prior to the molecular era. Yet, we know little about how well specific next-generation sequencing (NGS) techniques work with the degraded DNA typically extracted from museum specimens. Here, we use one type of NGS approach, sequence capture of ultraconserved elements (UCEs), to collect data from bird museum specimens as old as 120 years. We targeted 5060...

Data from: Inferring speciation history in the Andes with reduced-representation sequence data: an example in the bay-backed antpittas (Aves; Grallariidae; Grallaria hypoleuca s. l.)

Benjamin M. Winger, Peter A. Hosner, Gustavo A. Bravo, Andrés M. Cuervo, Natalia Aristizábal, Luis E. Cueto & John M. Bates
In the Andes, humid-forest organisms frequently exhibit pronounced genetic structure and geographic variation in phenotype, often coincident with physical barriers to dispersal. However, phylogenetic relationships of clades have often been difficult to resolve due to short internodes. Consequently, even in taxa with well-defined genetic structure, the temporal and geographic sequences of dispersal and vicariance events that led to this differentiation have remained opaque, hindering efforts to test the association between diversification and earth history and...

Data from: Historical climatic variability and geographical barriers as drivers of community composition in a biodiversity hotspot

Jessica A. Oswald, J. Gordon Burleigh, David W. Steadman, Scott K. Robinson & Andrew W. Kratter
Aim: To evaluate the roles of Quaternary (< 2.6 Ma) climatic stability and geologic barriers (i.e. the Andes Mountains) in shaping the modern community composition and patterns of endemism in Neotropical dry forest bird communities. Location: Marañón Valley and Tumbes, north-western Peru. Methods: We recorded presence and abundance of species in six dry forest bird communities on either side of the Andes Mountains. We used the data to calculate the beta diversity and phylogenetic beta...
