Just out @ Proceedings of the Royal Society B Lizards of the lost arcs: mid-Cenozoic diversification, persistence and ecological marginalization in the West Pacific Author(s) Paul M. Oliver, Rafe M. Brown, Fred Kraus, Eric Rittmeyer, Scott L. Travers, Cameron D. Siler Abstract: Regions with complex geological histories often have diverse and highly endemic biotas, yet inferring the ecological and historical processes shaping this relationship remains challenging. Here, in the context of the taxon cycle model

Just out @ Proceedings of the Royal Society B The evolution of tail weaponization in amniotes Author(s) Victoria M. Arbour, Lindsay E. Zanno Abstract: Weaponry, for the purpose of intraspecific combat or predator defence, is one of the most widespread animal adaptations, yet the selective pressures and constraints governing its phenotypic diversity and skeletal regionalization are not well understood. Here, we investigate the evolution of tail weaponry in amniotes, a rare

Just out @ Paleobiology Punctuated changes in the morphology of an endemic diatom from Lake Titicaca Author(s) Trisha L. Spanbauer, Sherilyn C. Fritz, Paul A. Baker Abstract: High levels of biodiversity and endemism in ancient lakes have motivated research on evolutionary processes in these systems. Drill-core records from Lake Titicaca (Bolivia, Peru), an ancient lake in the high-elevation Altiplano, record the history of climate, landscape dynamics, and diatom evolution. That record

Just out @ Evolution Out of the dark: 350 million years of conservatism and evolution in diel activity patterns in vertebrates Author(s) Samantha R. Anderson, John J. Wiens Abstract: Many animals are active only during a particular time (e.g., day vs. night), a partitioning that may have important consequences for species coexistence. An open question is the extent to which this diel activity niche is evolutionarily conserved or labile. Here, we

Just out @ Proceedings of the Royal Society B Testing the molecular clock using mechanistic models of fossil preservation and molecular evolution Author(s) Rachel C. M. Warnock, Ziheng Yang, Philip C. J. Donoghue Abstract: Molecular sequence data provide information about relative times only, and fossil-based age constraints are the ultimate source of information about absolute times in molecular clock dating analyses. Thus, fossil calibrations are critical to molecular clock dating, but competing methods are difficult to

Just out @ Proceedings of the Royal Society B Hierarchical complexity and the size limits of life Author(s) Noel A. Heim, Jonathan L. Payne, Seth Finnegan, Matthew L. Knope, Michał Kowalewski, S. Kathleen Lyons, Daniel W. McShea, Philip M. Novack-Gottshall, Felisa A. Smith, Steve C. Wang Abstract: Over the past 3.8 billion years, the maximum size of life has increased by approximately 18 orders of magnitude. Much of this increase is associated with two major evolutionary innovations: the evolution of eukaryotes from prokaryotic cells approximately 1.9 billion years ago (Ga),

Just out @ Nature Ecology & Evolution The palaeogenetics of cat dispersal in the ancient world Author(s) Claudio Ottoni, Wim Van Neer […] Eva-Maria Geigl Excerpt: The cat has long been important to human societies as a pest-control agent, object of symbolic value and companion animal, but little is known about its domestication process and early anthropogenic dispersal. Here we show, using ancient DNA analysis of geographically and temporally widespread

Just out @ BMC Evolutionary Biology Pre-Quaternary divergence and subsequent radiation explain longitudinal patterns of genetic and morphological variation in the striped skink, Heremites vittatus Author(s) Felix Baier, Andreas Schmitz, Hedwig Sauer-Gürth and Michael Wink Abstract: Background Many animal and plant species in the Middle East and northern Africa have a predominantly longitudinal distribution, extending from Iran and Turkey along the eastern Mediterranean coast into northern Africa. These species are potentially characterized by longitudinal patterns

On the News @ Science Title:  De-extinction, nomenclature, and the law Norman Wagner, Axel Hochkirch, Henrike Martin, Daniela Matenaar, Katja Rohde, Frank Wacht, Charlotte Wesch, Sarah Wirtz, Roland Klein, Stefan Lötters, Alexander Proelss, Michael Veith Summary: The concept of de-extinction, aimed at restoration of extinct species, is controversial. Improvements in de-extinction techniques (back-breeding, cloning, and genomic engineering) now provide the opportunity to attempt to resurrect extinct species. Up to 25 extinct

Just out @ Current Biology Infrasonic and Ultrasonic Hearing Evolved after the Emergence of Modern Whales Author(s) Mickaël J. Mourlam, Maeva J. Orliac Abstract: Mysticeti (baleen whales) and Odontoceti (toothed whales) today greatly differ in their hearing abilities: Mysticeti are presumed to be sensitive to infrasonic noises, whereas Odontoceti are sensitive to ultrasonic sounds. Two competing hypotheses exist regarding the attainment of hearing abilities in modern whales: ancestral low-frequency sensitivity or
