A study led by the CSIC finds that the Egyptian vulture selects the areas with the highest density of individuals to reproduce for the first time

The data have been obtained from the long-term monitoring programs of six populations of Egyptian vultures (Neophron percnopterus) from Spain and France. The study makes it possible to advance in the knowledge of the natal dispersal of long-lived territorial birds, such as the Egyptian vulture.
The median dispersal distance was 48 km, while there were cases of movement longer than 500 km to settle as breeders. In addition, it was detected that females and males followed different...

Gulls can spread weeds over large distances and between habitats

A study from the Doñana Biological Station has developed a seed dispersal model based on the movement of gulls monitored by GPS telemetry, while feeding in rice fields in Andalusia, South-West Spain.
Modelling shows that gulls can disperse weeds over large distances and between different hábitats, causing the exchange of weed and alien plant species between agricultural crops and natural areas.

A study led by the Doñana Biological Station assesses the combined impacts of weeds and climate change on crops

Crops worldwide are simultaneously affected by weeds, which reduce yield, and by climate change, which can negatively or positively affect both crop and weed species. While the individual effects of environmental change and of weeds on crop yield have been assessed, the combined effects have not been broadly characterized

Seagulls act as vectors of metals and arsenic between landfills and protected wetlands

Researchers from the Doñana Biological Station assessed the spatial variation in concentrations of ten metals in faeces of the lesser black-backed gull (Larus fuscus) wintering at seven localities in South-West Spain. They found high concentrations of metals in gull faeces, with several elements (arsenic, copper, molybdenum, lead and zinc) locally exceeding (by 2 to 11 times) derived Lowest Effect Level (LEL) values.

The European ShowCase project will help build bridges between agriculture and biodiversity conservation

Biodiversity on farmland is steeply declining throughout Europe and society at large is increasingly concerned about the loss of public goods, such as iconic local fauna and cultural landscapes. In this context, the SHOWCASE project was launched to create synergies and bridges of knowledge incentives between agricultural producers and biodiversity management practices with the aim of facilitating the agricultural sector’s transition towards more sustainable farming.
