Experts warn: Planned reforestation vital to prevent spread of wildfire

An international group of experts, led by the University of Granada (UGR), has signalled the need for carefully planned reforestation on a worldwide scale—and not simply in terms of planting as many trees as possible but, rather, planting specific species that can help curb the propagation of wildfires and that are able to re-sprout following fire damage. The experts have shared their views in an open Letter published in Science, one of the world’s most prestigious journals dealing with scientific matters.

Scientists analyse the fossil pollen of cedars that were deposited in the lakes of Sierra Nevada

A team of scientists from the University of Granada has analysed the pollen records of the Cedrus (the cedar), a forest species that disappeared from the Iberian Peninsula due to natural—mainly climatic—causes at some point in the Pleistocene, to study why this species is also now disappearing in the Middle Atlas and the Rif Mountains of Morocco.

UGR scientists prove that no glasses can enable colour-blind people to perceive new colours

This work is part of a strand of research being undertaken by the Department of Optics of the University of Granada (UGR) in Spain to analyse the effectiveness of various aids marketed as ostensibly ‘improving’ colour vision among colour-blind people. In 2018 and 2019, the research team demonstrated the ineffectiveness of two such products: EnChroma’s Cx-65 glasses and VINO’s 02 Amp Oxy-Iso glasses. Neither was found to improve the colour vision of colour-blind people.

Study provides new data on the complex ‘love–hate’ relationship between lions and hyaenas

A team of researchers, led by the University of Granada, has unravelled the complex relationship between the two species concerning the carrion on which they feed, which will help to better understand how the two largest African carnivores can coexist even in small natural reserves. Lions, the dominant species, show a greater preference for large animal carcasses, while hyaenas also feed off smaller carcasses, which are practically ignored by lions.
