Data from: Phylogenomics reveals novel relationships among Neotropical crocodiles (Crocodylus spp.)

Yoamel Milian-Garcia, George Amato, John Gatesy, Evon Hekkala, Natalia Rossi & Michael Russello
Extant species in the order Crocodylia are remnants of an ancient lineage of large-bodied archosaur reptiles. Despite decades of systematic studies, phylogenetic relationships among members of the genus Crocodylus (true crocodiles) in the Neotropics are poorly understood. Here we estimated phylogenomic relationships among the four extant Crocodylus species in the Americas. Species-tree reconstructions using genotypic data from 17,538 SNPs collected for 33 individuals spanning six Crocodylus species (four ingroup and two outgroup) revealed novel relationships...

Facultative chemosynthesis in a deep-sea anemone from hydrothermal vents in the Pescadero Basin, Gulf of California

Shana Goffredi, Cambrie Motooka, David Fike, Luciana Gusmão, Ekin Tilic, Greg Rouse & Estefanía Rodríguez
Background Numerous deep-sea invertebrates have formed symbiotic associations with internal chemosynthetic bacteria in order to harness inorganic energy sources typically unavailable to most animals. Despite success in nearly all marine habitats and their well-known associations with photosynthetic symbionts, Cnidaria remain without a clear dependence on hydrothermal vents and chemosynthetic bacterial symbionts specifically. Results A new chemosynthetic symbiosis between the sea anemone Ostiactis pearseae (Daly & Gusmão, 2007) and intracellular bacteria was discovered at ~3700 m...

Saproxylic fly diversity in a Costa Rican forest mosaic

Lance Jones & Amy Berkov
This paper presents the first assessment of the diversity of tropical saproxylic Diptera, done on the Osa Peninsula of Costa Rica. Forty-one trees representing nine species and six plant families were sampled in a rearing experiment. In total, 272 individuals attributable to 18 families of Diptera were reared. Low abundance and species richness of flies was observed overall. A majority of taxa were in saprophagous and mycophagous larval feeding guilds, followed by predators. Host associations,...

Disentangling interactions among mercury, immunity, and infection in a Neotropical bat community

Daniel Becker, Kelly Speer, Jennifer Korstian, Dmitriy Volokhov, Hannah Droke, Alexis Brown, Catherene Baijnauth, Ticha Padgett-Stewart, Hugh Broders, Raina Plowright, Thomas Rainwater, Brock Fenton, Nancy Simmons & Matthew Chumchal
Contaminants such as mercury are pervasive and can have immunosuppressive effects on wildlife. Impaired immunity could be important for forecasting pathogen spillover risks, as many land-use changes that generate mercury contamination also bring wildlife into close contact with humans and domestic animals. However, the interactions among contaminants, immunity, and infection are difficult to study in natural systems, and empirical tests of possible directional relationships remain rare. We capitalized on extreme mercury variation in a diverse...

Evolutionary and morphological patterns underlying carnivoran body shape diversity

Chris Law
The diversity of body shapes is one of the most prominent features of phenotypic variation in vertebrates. Biologists, however, still lack a full understanding of the underlying morphological components that contribute to its diversity, particularly in endothermic vertebrates such as mammals. In this study, I tested hypotheses pertaining to the evolution of the cranial and axial components that contribute to the diversity of carnivoran body shapes. I found three trends in the evolution of carnivoran...
