Data from: Horizontal transmission of Rickettsia felis between cat fleas, Ctenocephalides felis

Supanee Hirunkanokpun, Chutima Thepparit, Lane D. Foil & Kevin R. Macaluso
Rickettsia felis is a rickettsial pathogen primarily associated with the cat flea, Ctenocephalides felis. Although laboratory studies have confirmed that R. felis is maintained by transstadial and transovarial transmission in C. felis, distinct mechanisms of horizontal transmission of R. felis among cat fleas is undefined. Based on the inefficient vertical transmission of R. felis by cat fleas and the detection of R. felis in a variety of hematophagous arthropods, we hypothesize that R. felis is...

Data from: Is sexual selection driving diversification of the bioluminescent ponyfishes (Teleostei: Leiognathidae)?

Prosanta Chakrabarty, Matthew P Davis, W. Leo Smith, Zachary H Baldwin & John S Sparks
Sexual selection is a mechanism of speciation that theoretically could provide genetic isolation among populations and lead to an increase in diversification rates. In this study, we investigate the impact of potential sexual selection on the tempo and mode of ponyfish evolution. Ponyfishes (Leiognathidae) are bioluminescent marine fishes that exhibit sexually-dimorphic features of their unique light-organ system (LOS). Given that some leiognathid species have a sexually dimorphic LOS, whereas others do not, this family provides...

Data from: Small-scale variation in fuel loads differentially affects two co-dominant bunchgrasses in a species-rich pine savanna

Paul R. Gagnon, Kyle E. Harms, William J. Platt, Heather A. Passmore & Jonathan A. Myers
Ecological disturbances frequently control the occurrence and patterning of dominant plants in high-diversity communities like C4 grasslands and savannas. In such ecosystems disturbance-related processes can have important implications for species, and for whole communities when those species are dominant, yet mechanistic understanding of such processes remains fragmentary. Multiple bunchgrass species commonly co-dominate disturbance-dependent and species-rich pine savannas, where small-scale fuel heterogeneity may influence bunchgrass survival and growth following fires. We quantified how fire in locally...
