    Ecology and conservation of the endemic lizard Tropidurus hygomi in “restinga” habitats of the north coast of Bahia state, Brazil by Karina Vieira Martins, Eduardo José dos Reis Dias, Carlos Frederico Duarte da Rocha

    Published 2010-12-01
    “…Fragmentation of the landscape and habitat loss within natural ecosystems are the factors which are mainly responsible for reduction of species diversity by extinction events. The goal of thepresent study was elucidate whether the conservation status of restinga habitats on the northern coast of Bahia state was interfering with microhabitat use by the endemic lizard Tropidurus hygomi. …”

    Towards a Mathematical Description of Biodiversity Evolution by Jorge E. Horvath

    Published 2014-09-01
    “…The known solutions for the homogeneous problem are then tentatively related to the biodiversity curves of Sepkoski and Alroy et al., suggesting mostly an inertial behavior of the time evolution of the number of genera and a quadratic behavior in some long-term evolution after extinction events. We present the Green function for the dynamical system and apply it to the description of the recovery curve after the Permo-Triassic extinction, as recently analyzed by Burgess, Bowring and Shen. …”

    Scaled biotic disruption during early Eocene global warming events by S. J. Gibbs, P. R. Bown, B. H. Murphy, A. Sluijs, K. M. Edgar, H. Pälike, C. T. Bolton, J. C. Zachos

    Published 2012-11-01
    “…Here we quantify marine biotic variability through three million years of the early Eocene that include five hyperthermals, utilizing a method that allows us to integrate the records of different plankton groups through scenarios ranging from background to major extinction events. Our long time-series calcareous nannoplankton record indicates a scaling of biotic disruption to climate change associated with the amount of carbon released during the various hyperthermals. …”

    Distribution of the fittest individuals and the rate of Muller's ratchet in a model with overlapping generations. by Jakob J Metzger, Stephan Eule

    Published 2013-01-01
    “…As a click in this regime is caused by a rare, large fluctuation from a metastable state, we do not resort to a diffusion approximation but apply an approximation scheme which is especially well suited to describe extinction events from metastable states. This method also allows for a derivation of expressions for the quasi-stationary distribution of the fittest class. …”
