The amphipod Corophium multisetosum (Corophiidae) in Ria de Aveiro (NW Portugal...

The population of Corophium multisetosum Stock, 1952 in Areao displayed a semiannual, iteroparous life history. Mean longevity was similar to6 mo, with the estimated life span longer for overwintering individuals born in autumn than for individuals born in spring. Length-frequency data indicated that the length increment per moult is probably higher in males than females; however females moulted more frequently...

The amphipod Corophium multisetosum (Corophiidae) in Ria de Aveiro (NW Portugal...

The abundance and biomass of Corophium multisetosum Stock, 1952 were determined from benthic corer samples collected monthly over 1 yr in the upper reaches of Canal de Mira (Ria de Aveiro, Portugal). Both density and biomass over the sampling period were negatively correlated with water temperature and positively correlated with chlorophyll n concentration in the sediment. C, multisetosum density was significan...

Building a reference DNA barcode library for marine amphipods of Portugal

Systematic and evolutionary insights derived from mtDNA COI barcode diversity i...

Decapods are the most recognizable of all crustaceans and comprise a dominant group of benthic invertebrates of the continental shelf and slope, including many species of economic importance. Of the 17635 morphologically described Decapoda species, only 5.4% are represented by COI barcode region sequences. It therefore remains a challenge to compile regional databases that identify and analyse the extent and pa...

High ethanol productivity by fermentation of concentrated industrial substrates...

Ethanol production from high-glucose industrial substrates using ethanol-tolera...

Ethanol is well known as a toxic metabolite for yeast cells. Thus, strains that can grow well under high ethanol stress condition are highly desirable. This work aims to select and characterize Saccharomyces cerevisiae strains with improved ethanol tolerance. Moreover, it aims to evaluate the feasibility of industrial residues as fermentation media and to optimize the composition of such media. The ethanol prod...

Spatial and seasonal changes of brackish peracaridan assemblages and their rela...

The shallow-water fauna of 2 main channels in the Ria de Aveiro (Canal de Ovar and Canal de Mira) was sampled between June 1995 and June 1996 using a suprabenthic sled. Samples were collected monthly at 5 stations and every third month at 11 other stations, covering both channels from the lower to the upper reaches. The channels differ in their hydrodynamics, in the distribution of the sediment environments and...

On the structure of the neritic suprabenthic communities from the Portuguese co...

This work presents the investigations made on the neritic suprabenthic communities of the Portuguese margin (continental shelf and upper slope) exposed to seasonal upwelling. These communities were sampled during the AVEIRO-94 cruise at 5 sites located along an E-W bathymetric transect from 21 to 299 m depth using a suprabenthic sled with superposed nets. In the 0 to 100 cm water layer, the total densities rang...
