We have undertaken an exhaustive review of the literature to check if the ichnogenus Oldhamia could be used as a biostratigraphical tool in the Cambrian. On the 19 occurrences observed worldwide and positioned in the recent global chronostratigraphy of the Cambrian, onl...

Central America is characterized by the subduction of the oceanic Cocos Plate underneath the Caribbean Plate and Panama Microplate along the Middle America Trench, in a setting that is transitional between oceanic island arc and continental active margin subduction. In ...

During the past 10 years, large developments and improvements on the technical possibilities and operational availability of full-size, Class III deep ocean work ROVs took place (≫ 3000 m). This is especially true for the marine science community. Where in the early 90'...

Data on size structure and maturity of the commercially exploited Loligo gahi population in Falkland Island waters were collected by the Fisheries Department of the Falkland Islands Government for the years 1987–1991. Three methods were used to define the number of broo...

Despite their frequent occurrence and strong impacts on native biota, biological invasions can long remain undetected. One reason for this is that an invasive species can be morphologically similar to either native species or introduced species previously established in...

It is now well known that traces of molecular gases such as hydrogen or nitrogen can affect significantly the electrical characteristics, sputtering rates and relative intensities of emission lines in glow discharge optical emission spectrometry (GD-OES). These changes,...
