Reevaluating claims of ecological speciation in Halichoeres bivittatus

Dan Warren, Ron Eytan, Alex Dornburg, Teresa Iglesias, Matt Brandley & Peter Wainwright
Allopatry has traditionally been viewed as the primary driver of speciation in marine taxa, but the geography of the marine environment and the larval dispersal capabilities of many marine organisms render this view somewhat questionable. In marine fishes, one of the earliest and most highly cited empirical examples of ecological speciation with gene flow is the slippery dick wrasse, Halichoeres bivittatus. Evidence for this cryptic or incipient speciation event was primarily in the form of...

Clinging performance on natural substrates predicts habitat use in anoles and geckos

Amber Wright, Stevie Kennedy-Gold, Emily Naylor, Robyn Screen, Carla Piantoni & Timothy Higham
1. For arboreal lizards, the ability to cling or adhere to the substrate is critical for locomotion during prey capture, predator escape, thermoregulation, and social interactions. Thus, selection on traits related to clinging is likely strong. 2. Correlations between morphology, performance, and habitat use have been documented in arboreal lizards, providing a framework for using functional traits to predict habitat use in the field. 3. We tested the hypothesis that clinging performance predicts habitat use...

Feedbacks between forest structure and an opportunistic fungal pathogen

Christopher Lee, Ricardo Holdo & Rose-Marie Muzika
Abiotic stresses, physiological dysfunction, forest stand dynamics, and primary tree attackers (native and non-native) are all recognized as important contributors to both anomalous tree mortality and background tree mortality, and thus as important influences on biogeochemical cycling and habitat for associated terrestrial organisms. Opportunistic and latent tree pathogens and insect pests have largely been left out of this discussion, probably because they are difficult to monitor and their effects sometimes more diffuse, yet they play...
