Estuarine Salinity Response to Freshwater Pulses

Journal of Geophysical Research: Oceans, Volume 127, Issue 11, November 2022., 2022
Abstract Freshwater pulses (during which river discharge is much higher than average) occur in many estuaries and strongly impact estuarine functioning. To gain insight into the estuarine salinity response to freshwater pulses, an idealized model is presented.

The importance of seawater tolerance and native status in mediating the distribution of inland fishes

Journal of Biogeography, Volume 49, Issue 11, Page 2037-2049, November 2022., 2022
Abstract Aim Unravelling the ecological and historical factors that underlie species distributions has challenged ecologists for a long time. Thus, our objective is to understand the role of environmental variables explaining the distribution of three major eco‐evolutionary groups of inland fishes (Darlington's divisions: primary, i.e.

The impact of water quality changes on the socio-economic system of the Guadiana Estuary: an assessment of management options

Ecology and Society, 2012
Tourism related to bathing has a growing economic importance in the Guadiana Estuary in southern Spain and Portugal. Polls of local public opinion showed an awareness of potential and current threats to the aquatic environment posed by regulation of ...

Effects of tidal-forcing variations on tidal properties along a narrow convergent estuary [PDF]

, 2018
A 1D analytical framework is implemented in a narrow convergent estuary that is 78 km in length (the Guadiana, Southern Iberia) to evaluate the tidal dynamics along the channel, including the effects of neap-spring amplitude variations at the mouth.

Biomarkers in Nereis diversicolor (Polychaeta: Nereididae) as management tools for environmental assessment on the southwest Iberian coast

Scientia Marina, 2013
The environmental quality of the southwest Iberian coast was assessed in different areas (Ria Formosa Lagoon, Guadiana Estuary and Cádiz Bay) focusing on metal contamination (Cd, Cu, Ni, Pb and Zn) in Nereis diversicolor whole tissues.

The distribution of estuarine fish larvae: nutritional condition and co-occurrence with predators and prey [PDF]

, 2000
Fish larvae were collected monthly between March and September 1997 in the Mira and Guadiana estuaries (southern Portugal). Hydrological parameters were registered and zooplankton samples were obtained simultaneously. Densities of fish larvae (ind.100 m(-

Morphological response of the saltmarsh habitats of the Guadiana estuary due to flow regulation and sea-level rise [PDF]

, 2016
In the context of rapid sea-level rise in the 21st century, the reduction of fluvial sediment supply due to the regulation of river discharge represents a major challenge for the management of estuarine ecosystems.
