Biological Correlates of Extinction Risk in Bats
The American Naturalist, 2003(Uploaded by Plazi for the Bat Literature Project) We investigated patterns and processes of extinction and threat in bats using a multivariate phylogenetic comparative approach. Of nearly 1,000 species worldwide, 239 are considered threatened by the International Union for Conservation of Nature and Natural Resources (IUCN) and 12 are extinct.

A Biologically-Inspired Model for Mass Extinction in Genetic Algorithms
2021 IEEE Congress on Evolutionary Computation (CEC), 2021Mass extinction events have previously been shown to be a catalyst for accelerating the rate of evolution in genetic algorithms. This increased evolution rate combined with a destabilization of the dynamic equilibrium of the genetic algorithm can allow the algorithm to overcome local maxima in the solution space; however, most implementations of mass ...

The Functions of Biological Diversity in an Age of Extinction
Science, 2012Environmental Determinism? Earth's millions of species influence a wide range of environmental processes, including elemental cycling, the stability of ecosystems, and the goods and services they provide. Naeem et al. (p.

OMICS: A Journal of Integrative Biology, 2003
AS BIOINFORMATICIANS, we think of biological data in terms of an experiment and as a snapshot of some biological process. As such, we store and process large quantity of this data, and we seek to preserve the “sanctity of this data in perpetuity.” However, our users, the biologists, never look back at old data once they have reconciled the data by an ...

Biological Selectivity of Extinction: A Link between Background and Mass Extinction
PALAIOS, 1986The phenomenon of non-random or selective survival across major extinction boundaries in the geologic past is poorly understood but increasingly recognized as a critical area for future research. A current hypothesis, developedfrom a comparison of extinction patterns among Late Cretaceous molluscs, is that biological adaptations of organisms effectual ...

Biological Extinction in Earth History
Science, 1986Virtually all plant and animal species that have ever lived on the earth are extinct. For this reason alone, extinction must play an important role in the evolution of life. The five largest mass extinctions of the past 600 million years are of greatest interest, but there is also a spectrum of smaller events, many of which indicate biological ...

On impacts and extinction: biological solutions to biological problems
Journal of Paleontology, 1990There appears to be an overwhelming urge in the study of earth sciences currently to discover the “cosmic generality.” Certainly, no observational and descriptive aspects of the study of earth history can be concluded until one has placed the observations into a broader context.

Is the Tasmanian tiger extinct? A biological–economic re-evaluation
Ecological Economics, 2003Abstract In the 1890s, a bounty scheme was implemented to rid Tasmania of the thylacine or Tasmanian tiger, a marsupial predator believed to wreak havoc on imported sheep flocks. The thylacine is now officially ‘possibly extinct’ and although, repeatedly, there have been alleged sightings in the wild, most people now believe the species is extinct as

Biological response: extinction
1996The third major type of response of organisms to global climatic change is extinction: failure to survive the new conditions. The Quaternary is characterized by its particularly extreme climatic oscillations, and also for the occurrence of wholescale extinctions of large mammals at about the glacial–Holocene transition (Grayson 1984a).

Global extinctions and the biological evolution
Journal of Palaeosciences, 1995The biosphere evolution is shown to accompany geodynamic processes and follow different-order cycles of the galactic motion of the Solar System. Restricted to critical points of the cycles are global epochs of nascencies and extinctions of taxa whose rank corresponds to a scale of geodynamic activation at their origin in critical points of the Earth’s ...
