Cunha, M. R.; Sorbe, J. C.; Moreira, M. H.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...

Cunha, M. R.; Moreira, M. H.; Sorbe, J. C.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...
Spatial and seasonal changes of brackish peracaridan assemblages and their rela...
Cunha, M. R.; Sorbe, J. C.; Moreira, M. H.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...
Cunha, M. R.; Sorbe, J. C.; Bernardes, C.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...
