Structural Color in Amber-Entombed Wasp: A Detailed Study Using NS-FDTD Simulations
IEEE AccessThe multilayer reflectors of insect epidermis can produce unique structural color through interactions with light. Many fossilized insects, like amber-entombed wasps, present structural colors. However, how this multilayer structure and structural colors

Simple Model of Large Scale Organization in Evolution [PDF]
arXiv, 1996 A mathematical model of interacting species filling ecological niches left by the extinction of others is introduced. Species organize themselves into genera of all sizes. The size of a genus on average grows linearly with its age, confirming a general relation between Age and Area proposed by Willis.

Mass extinctions and supernova explosions [PDF]
, 2016 A nearby supernova (SN) explosion could have negatively influenced life on Earth, maybe even been responsible for mass extinctions. Mass extinction poses a significant extinction of numerous species on Earth, as recorded in the paleontologic, paleoclimatic, and geological record of our planet.

PLoS ONE, 2014 Neotaphonomic studies of large carnivores are used to create models in order to explain the formation of terrestrial vertebrate fossil faunas. The research reported here adds to the growing body of knowledge on the taphonomic consequences of large ...

A mathematical model for Neanderthal extinction [PDF]
arXiv, 1997 A simple mathematical homogeneous model of competition is used to describe Neanderthal extinction in Europe. It considers two interacting species, Neanderthals and Early Modern Men, in the same ecological niche. Using paleontological data we claim that the parameter of similarity, between both species, fluctuates between 0.992 and 0.997.

Geological workshop for primary schools
Geologija, 2010 Systematical teaching of geology is (yet) not established in primary and secondary school in Slovenia. In primaryschool, geological topics are divided among numerous subjects and levels therefore they receive more attention onlyif alternative courses or ...

Mathematical Modeling of Extinction of Inhomogeneous Populations [PDF]
arXiv, 2016 Mathematical models of population extinction have a variety of applications in such areas as ecology, paleontology and conservation biology. Here we propose and investigate two types of sub-exponential models of population extinction.The results of performed analysis show that the principle of minimum of information loss is the underlying law for the ...

Beyond the print—virtual paleontology in science publishing, outreach, and education
Journal of Paleontology, 2014 Virtual paleontology unites a variety of computational techniques and methods for the visualization and analysis of fossils. Due to their great potential and increasing availability, these methods have become immensely popular in the last decade. However,

Digitization workflows for paleontology collections
, 2016 The development of digitization workflows is an essential part of any formalized large-scale digitization program. Paleontological collections literature has addressed the need for, and utility of, digitized collections for nearly four decades, but no ...
