The global economic costs of invasive aquatic crustaceans amounted to at least US$ 271 million

An international scientific team from Czech Republic, Spain, Germany, the UK, the USA, Italy, and France has compilled all existing published costs of invasive aquatic crustaceans and pointed out knowledge gaps.
Invasive crayfish and crabs had the highest costs, US$ 121 and US$ 150 million, respectively. Taxonomic, geographical, and temporal gaps suggest that these costs are still severely underestimated.

Researchers track nocturnal flight to reduce seabird mortality due to light pollution

The LuMinAves project in which the Doñana Biological Station (EBD-CSIC) participates has collected data to manage the seabird mortality induced by artificial lights, an important phenomenon affecting seabird conservation in the world
? With the use of GPS devices and satellite images, the researchers could monitor for the first time the night flights of Cory’s shearwaters, when they leave their nests and fly towards the sea

An EBD study shows that human action negatively affects frugivorous birds in Doñana

A study led by the Doñana Biological Station (EBD-CSIC) found that fruit-eating birds (frugivorous) in Doñana have experienced negative changes in the last 40 years: a decrease in their abundance, a lower fat reserve, and advances in their migratory timing.
? This could be due to vegetation shifts and increasing temperatures associated with climate change. Changes in the timing of migratory birds’ arrivals and departures can lead to a lack of synchronization between birds and fruit...

Grey herons as vectors of plant seeds and aquatic invertebrates

Our findings showcase the potential of predatory waterbirds as vectors of plants and invertebrates, and how they may facilitate connectivity between freshwater and terrestrial habitats.

Apple snail control does not cause many of the declines of waterbird abundance in the Ebro Delta Natural Park

A study led by the Doñana Biological Station (EBD-CSIC) and the Pyrenean Institute of Ecology (IPE-CSIC) concludes that stopping winter floods of rice field in the Ebro Delta, a management to control the invasion of the apple snail, have not had an impact to date on the abundance of many waterbirds species wintering in the area.
This apple snail control has been highly controversial due to its potential side effects on waterbird conservation. However, by assessing long series of...
