Biotic predictors with phenological information improve range estimates for migrating monarch butterflies in MexicoJamie M. Kass, Robert P. Anderson, Alejandro Espinosa-Lucas, Verónica Juárez-Jaimes, Esteban Martínez-Salas, Francisco Botello, Gloria Tavera, José Juan Flores-Martínez & Víctor Sánchez-Cordero
Although long-standing theory suggests that biotic variables are only relevant at local scales for explaining the patterns of species’ distributions, recent studies have demonstrated improvements to species distribution models (SDMs) by incorporating predictor variables informed by biotic interactions. However, some key methodological questions remain, such as which kinds of interactions are permitted to include in these models, how to incorporate the effects of multiple interacting species, and how to account for interactions that may have...
Genomic analysis of the only blind cichlid reveals extensive inactivation in eye and pigment formation genesS. Elizabeth Alter
Trait loss represents an intriguing evolutionary problem, particularly when it occurs across independent lineages. Fishes in light-poor environments often evolve “troglomorphic” traits, including reduction or loss of both pigment and eyes. Here we investigate the genomic basis of trait loss in a blind and depigmented African cichlid, Lamprologus lethops, and explore evolutionary forces (selection and drift) that may have contributed to these losses. This species, the only known blind cichlid, is endemic to the lower...
Data from: Out of the Orient: Post-Tethyan transoceanic and trans-Arabian routes fostered the spread of Baorini skippers in the AfrotropicsEmmanuel F.A. Toussaint, Roger Vila, Masaya Yago, Hideyuki Chiba, Andrew D. Warren, Kwaku Aduse-Poku, Caroline Storer, Kelly M. Dexter, Kiyoshi Maruyama, David J. Lohman & Akito Y. Kawahara
The origin of taxa presenting a disjunct distribution between Africa and Asia has puzzled biogeographers for more than a century. This biogeographic pattern has been hypothesized to be the result of transoceanic long‐distance dispersal, Oligocene dispersal through forested corridors, Miocene dispersal through the Arabian Peninsula or passive dispersal on the rifting Indian plate. However, it has often been difficult to pinpoint the mechanisms at play. We investigate biotic exchange between the Afrotropics and the Oriental...
Data from: A new null model approach to quantify performance and significance for ecological niche models of species distributionsCorentin L. Bohl, Jamie M. Kass & Robert P. Anderson
Aim: Ecological niche modelling requires robust estimation of model performance and significance, but common evaluation approaches often yield biased estimates. Null models provide a solution but are rarely used in this field. We implemented an important modification to existing null-model tests, evaluating null models with the same withheld records that were used to evaluate the real model. We built and evaluated models across a range of modelling scenarios and for various performance measures using the...
Accumulating evidence indicates that the anterior insular cortex (AIC) mediates interoceptive attention, which refers to attention towards physiological signals arising from the body. However, the necessity of the AIC in this process has not been demonstrated. Using a novel task that directs attention toward breathing rhythm, we assessed the involvement of the AIC in interoceptive attention in healthy participants using functional magnetic resonance imaging and examined the necessity of the AIC in interoceptive attention in...
Links between prey assemblages and poison frog toxins: a landscape ecology approach to assess how biotic interactions affect species phenotypesIvan Prates, Andrea Paz, Jason Brown & Ana Carnaval
Ecological studies of species pairs showed that biotic interactions promote phenotypic change and eco-evolutionary feedbacks. However, it is unclear how phenotypes respond to synergistic interactions with multiple taxa. We investigate whether interactions with multiple prey species explain spatially structured variation in the skin toxins of the Neotropical poison frog Oophaga pumilio. Specifically, we assess how dissimilarity (i.e., beta diversity) of alkaloid-bearing arthropod prey assemblages (68 ant species) and evolutionary divergence between frog populations (from a...
