New Pumarejo Bridge over Magdalena River

IABSE Reports, 2022
<p>The New Pumarejo Bridge over Magdalena River in Barranquilla, Colombia, is one of the most relevant bridges built over the past few years in South America. The bridge has a total length of 2173 m without expansion joints, divided in two access viaducts, 618 and 755 m long, and a cable-stayed central stretch of 800 m with a main 380 m long span

Potamodromous migrations in the Magdalena River basin: bimodal reproductive patterns in neotropical rivers

Journal of Fish Biology, 2016
Magdalena River basin potamodromous fishes have two annual reproductive seasons: the subienda in the first half of the year and the mitaca in the second. Both upstream migrations are c. 30–45 days long; after that, with the onset of the rainy season, fishes spawn and remain in the river (resident individuals) or start a downstream movement (the bajanza)

Magdalena, river of Colombia

Scottish Geographical Magazine, 1981
Abstract Problems of environmental perception are often critical in Third World development. Most Colombian decision‐makers today believe that the physical navigability of the Magdalena river has greatly deteriorated: after dominating Colombian transport for over four centuries, the river has lost its place to road and rail in the last twenty years ...

The Magdalena River fresh water fishes and fisheries

Aquatic Ecosystem Health & Management, 2007
The Magdalena River Basin is the most important region of Colombia in terms of development and economy. About 80% of its population lives in this basin and traditionally its waters have produced more than 60% of fish consumed in the country. Nonetheless, from a production of nearly 80,000 ton yr− 1 in the 1970s, currently those fisheries produce only ...

Upper thermal tolerance and population implications for the Magdalena River stingray Potamotrygon magdalenae

Journal of Fish Biology
AbstractKnowledge of thermal tolerance limits provides important clues to the capacity of a species to withstand acute and chronic thermal changes. Climate models predict the increase and intensification of events such as heat waves, therefore understanding the upper thermal limits that a species can tolerate has become of utmost importance.
