Mass Extinction in a Simple Mathematical Biological Model
, 1997 Introducing the effect of extinction into the so-called replicator equations in mathematical biology, we construct a general model of ecosystems. The present model shows mass extinction by its own extinction dynamics when the system initially has a large number of species ( diversity).

Phylogenetically clustered extinction risks do not substantially prune the Tree of Life. [PDF]
PLoS ONE, 2011 Anthropogenic activities have increased the rate of biological extinction many-fold. Recent empirical studies suggest that projected extinction may lead to extensive loss to the Tree of Life, much more than if extinction were random.

Extinction events can accelerate evolution. [PDF]
PLoS ONE, 2015 Extinction events impact the trajectory of biological evolution significantly. They are often viewed as upheavals to the evolutionary process. In contrast, this paper supports the hypothesis that although they are unpredictably destructive, extinction ...

Permian-Triassic insect diversity revealed by fossils from China [PDF]
BIO Web of Conferences, 2023 Most of the research on Paleoentomology focuses on describing morphology and classification of one species of fossil insects. However, there is little information on the temporal diversity of insects during the Permian and Triassic periods.

The ethics of species extinctions
Cambridge Prisms: Extinction, 2023 This review provides an overview of the ethics of extinctions with a focus on the Western analytical environmental ethics literature. It thereby gives special attention to the possible philosophical grounds for Michael Soulé’s assertion that the untimely

Survival of small populations under demographic stochasticity [PDF]
, 1992 We estimate the mean time to extinction of small populations in an environment with constant carrying capacity but under stochastic demography. In particular, we investigate the interaction of stochastic variation in fecundity and sex ratio under several

Targets for maintenance of dead wood for biodiversity conservation based on extinction thresholds [PDF]
, 2006 Forestry decreases the amount of dead wood, thereby threatening the persistence of many saproxylic (wood-living) organisms. In this article, we discuss how targets for efforts to maintain and restore dead wood in managed forest landscapes should be ...

Fear conditioning- and extinction-induced neuronal plasticity in the mouse amygdala [PDF]
, 2009 Experience-dependent changes in behavior are mediated by long-term functional modifications in brain circuits. To study the underlying mechanisms, our lab is using classical auditory fear conditioning, a simple and robust form of associative learning. In

Local extinction and colonisation in native and exotic fish in relation to changes in land use [PDF]
, 2011 Distribution patterns of many native and exotic fish species are well documented, yet little is known about the temporal dynamics of native and exotic diversity in relation to changes in land use.

Journal of Marine Science and Engineering, 2023 The Late Ordovician–Early Silurian period was a significant transitional phase in geological history and has garnered global interest. This study focuses on the black shale series of the Wufeng Formation–Longmaxi Formation of the Upper Ordovician–Lower ...
