Patterns in estuarine macrofauna body size distributions: The role of habitat a...

Schwinghamer's (1981) habitat architecture hypothesis for body mass spectra in marine sediments predicts a single macrofauna mode in response to the bulk nature of the sediment. This proposition was examined for intertidal macrofauna from a well-studied estuarine system, using kernel density estimation to define modality and the locations of peaks and troughs. Three sedimentary environments and habitats were ex...

Effects of local and large-scale climate patterns on estuarine resident fishes:...

Large-scale and local climate patterns are known to influence several aspects of the life cycle of marine fish. In this paper, we used a 9-year database (2003e2011) to analyse the populations of two estuarine resident fishes, Pomatoschistus microps and Pomatoschistus minutus, in order to determine their relationships with varying environmental stressors operating over local and large scales. This study was perf...

Influence of benthic macroinvertebrates on the erodability of estuarine cohesiv...

The impact of three dominating benthic invertebrates on sediment stability and erosion conditions of cohesive sediments in the Mondego Estuary, Portugal, was examined in laboratory annular flume experiments. The purpose was to test how the life habits and body size of the three involved species (Hydrobia ulvae, Nereis diversicolor and Scrobicularia plana) in terms of density or biomass influence sediment erosio...

Education, capacity building and public awareness for including ecosystem servi...

The contribution of scientific research for integrated coastal management: the ...

The present paper quantifies and summarizes the research performed in the Mondego estuary (Portugal) over the last decades. Online databases were used to quantitatively assess the international publications, the master dissertations and PhD theses focused in the research about that estuary, from 1989 to 2012. In general, there had been a notable growth trend in publication output. Estuarine, Coastal and Shelf S...

The use of an estuarine system (Mondego estuary, Portugal) as didactic tool to ...

The present paper reviews and discusses the use of the Mondego estuary (Portugal) ecosystem as educational tool for science and environmental teachers/educators. The Mondego estuary is a coastal area of acknowledged high socioeconomic and environmental value (National Ecological Reserve, Important Bird Area and RAMSAR site) whose characteristics (e.g. two distinct subsystems with different physicochemical and e...

Influence of sex and age on PCBs accumulation in the commercial fish Chelon lab...

Thicklip grey mullet, Chelon labrosus, is an important commercial fish species and has been studied worldwide. However, no recent studies have been made regarding polychlorinated biphenyls (PCBs) in wild C. labrosus. Due to that, the concentration of 13 PCBs congeners was measured in muscles and livers, of males and females, of C. labrosus of different ages, allowing the estimation of PCB bioaccumulation throug...

Large-scale and local climate patterns are known to influence several aspects of the life cycle of marine fish. In this paper, we used a 9-year database (2003–2011) to analyse the populations of two estuarine resident fishes, Pomatoschistus microps and Pomatoschistus minutus, in order to determine their relationships with varying environmental stressors operating over local and large scales.

Sociocultural and educational factors in the sustainability of coastal zones : ...

Purpose - Environmental threats of immediate risk in areas such as coastal zones (CZ) have aroused new trends of citizenship and participatory democracy. This article intends to analyse elements within those trends, such as environmental culture; socio-political context; dynamics of social associative movement and integration of local knowledge. It also aims to contribute to an overview of the opportunities and...

Impact of climate variability on ichthyoplankton communities: An example of a s...

Recent variations in the precipitation regime across southern Europe have led to changes in river fluxes and salinity gradients affecting biological communities in most rivers and estuaries. A sampling programme was developed in the Mondego estuary, Portugal, from January 2003 to December 2008 at five distinct sampling stations to evaluate spatial, seasonal and inter-annual distributions of fish larvae. Gobiida...
