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,...

Le développement de la mytiliculture dans un bassin conchylicole peut aboutir à la surexploitation du site avec des conséquences néfastes pour les populations en cours d'exploitation. Pour cette raison, il est particulièrement important de développer un plan d'aménageme...

Abstract The presented investigation focuses on the correlation between concrete physical quantities and resulting modifications. The idea is that not the different manufacturing processes itself produce the modifications but the generated physical and chemical loads. T...

Review of several recent ocean surface wave models finds that while comprehensive in many regards, these spectral models do not satisfy certain additional, but fundamental, criteria. We propose that these criteria include the ability to properly describe diverse fetch c...

Calculations of air-mass factors (AMFs) for ground-based zenith-sky UV-visible spectrometers are presented and discussed. Causes and size of errors in AMFs of ozone in the visible are evaluated. Errors can be caused by approximations in the calculation (intensity-weight...

Abstract Diptera is one of the biggest insect orders and displays a large diversity of visual adaptations. Similarly to other animals, the dipteran visual process is mediated by opsin genes. Although the diversity and function of these genes are well studied in key mode...

Three Ecopath models were built to reproduce 3 experimental treatments carried out in earthen ponds located in Olhao, southern Portugal, to understand the energy transferred and the ecosystem state in integrated multi-trophic aquaculture (IMTA). These earthen ponds beha...

Les poissons des récifs coralliens ont souvent une forte structuration spatio-temporelle de leur distribution et de leur abondance, mais les facteurs qui l’influencent sont encore peu connus. Cette étude a pour but d’analyser la distribution spatiale des communautés de ...
