FOSSIL FOOTPRINTS FROM THE GRAND CANYON : THIRD CONTRIBUTION ( With Five Plates )

Frozen Footprints

Bibliometrics has the ambitious goal of measuring science. To this end, it exploits the way science is disseminated trough scientific publications and the resulting citation network of scientific papers. We survey the main historical contributions to the field, the most interesting bibliometric indicators, and the most popular bibliometric data sources. Moreover, we discuss distributions common...

Comment and Reply on "Fossil vertebrate footprints in the Coconino Sandstone (Permian) of northern Arizona: Evidence for underwater origin" COMMENT

Brand and Tang (1991) proposed that certain unusual vertebrate trackways "point to subaqueous deposition for at least part of the Coconino Sandstone." They supported their conclusions by demonstrating that western newts produce similar trackway configurations in aquarium experiments. While it is encouraging to see vertebrate ichnology play such a prominent role in fundamental questions concerni...

Anthropogenic footprints on biodiversity

One of the most concerning issues to modern ecology and society is the ongoing loss of biodiversity. Ecosystems are now losing species at rates only seen in previous mass extinction events (Hails, 2008; Barnosky et al., 2011) with rates of extinction between 100 and 1000 times higher than pre-human levels (Pimm et al., 1995). This loss, in turn, is impairing the functioning of ecosystems (Worm ...
