Just out @ Nature Ecology and Evolution Cooperative interactions within the family enhance the capacity for evolutionary change in body size Author(s) Benjamin J. M. Jarrett, Matthew Schrader, Darren Rebar, Thomas M. Houslay & Rebecca M. Kilner Abstract: Classical models of evolution seldom predict the rate at which populations evolve in the wild. One explanation is that the social environment affects how traits change in response to natural selection. Here

Just out @ Nature Ecology and Evolution Early bursts of diversification defined the faunal colonization of land Author(s) Nicholas J. Minter, Luis A. Buatois, M. Gabriela Mángano, Neil S. Davies, Martin R. Gibling, Robert B. MacNaughton & Conrad C. Labandeira Abstract: The colonization of land was one of the major events in Earth history, leading to the expansion of life and laying the foundations for the modern biosphere. We examined

Just out @ Current Biology Plasticity and Convergence in the Evolution of Short-Necked Plesiosaurs Author(s) Valentin Fischer, Roger B.J. Benson, Nikolay G. Zverkov, Laura C. Soul, Maxim S. Arkhangelsky, Olivier Lambert, Ilya M. Stenshin, Gleb N. Uspensky, Patrick S. Druckenmiller Abstract: Plesiosaurs were the longest-surviving group of secondarily marine tetrapods, comparable in diversity to today’s cetaceans. During their long evolutionary history, which spanned the Jurassic and the Cretaceous (201 to 66

On the News @ The Guardian Title:  What do the Tour de France and fossils have in common? Excerpt: “Trilobites are common fossils. Resembling nothing so much as a glorified woodlouse, these animals teemed in our oceans for millions of years. The first fossils are around 520 million years old, while the final demise of one last group of survivors took place 250 million years ago, in the Earth’s biggest known

Just out | Five palaeobiological laws needed to understand the evolution of the living biota @ Nature Ecology & Evolution

Just out @ Nature Ecology & Evolution Five palaeobiological laws needed to understand the evolution of the living biota Author(s) Charles R. Marshall Abstract: The foundations of several disciplines can be expressed as simple quantitative laws, for example, Newton’s laws or the laws of thermodynamics. Here I present five laws derived from fossil data that describe the relationships among species extinction and longevity, species richness, origination rates, extinction rates and diversification.

Just out | Interactions within and between clades shaped the diversification of terrestrial carnivores @ Evolution

Just out @ Evolution Interactions within and between clades shaped the diversification of terrestrial carnivores Author(s) Mathias M. Pires, Daniele Silvestro, Tiago B. Quental Abstract: A longstanding debate in evolutionary biology and paleontology is whether ecological interactions such as competition impose diversity dependence on speciation and extinction rates. Here we analyze the fossil record of terrestrial mammalian carnivores in North America and Eurasia using a Bayesian framework to assess whether their

Just out | Trilobite ‘pelotons’: possible hydrodynamic drag effects between leading and following trilobites in trilobite queues @ Palaeontology

Just out @ Palaeontology Trilobite ‘pelotons’: possible hydrodynamic drag effects between leading and following trilobites in trilobite queues Author(s) Hugh Trenchard, Carlton E. Brett, Matjaž Perc Abstract: Energy saving mechanisms in nature allow following organisms to expend less energy than leaders. Queues, or ordered rows of individuals, may form when organisms exploit the available energy saving mechanism while travelling at near-maximal sustainable metabolic capacities; compact clusters form when group members travel

Just out @ Palaeontology Non-traditional isotope perspectives in vertebrate palaeobiology Author(s) Jeremy E. Martin, Theo Tacail, Vincent Balter Abstract: The recent development of multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) notably in the disciplines of earth sciences, now allows the precise measurement of isotope ratios, even at low concentration. Non-traditional isotope systems, such as alkaline earth (Ca, Mg) and transition (Cu, Fe, Zn) metals are now being measured in a variety
