África tiene la mitad de los leones que tenía hace 20 años, pero no culpe a los trofeos de caza. El asesinato del León Cecil de Zimbabwe, ha puesto los reflectores sobre la alarmante disminución de los leones en África, escriben Lochran Traill y Norman Owen-Smith. Pero para salvar a la especie, no hay que obsesionarse con la obtención de trofeos, sino con problemas mucho más graves, como la falta de desarrollo y la fragmentación del hábitat.
People who eat spicy foods nearly every day have a 14% lower risk of death compared with those who consume spicy foods less than once a week, according to a new study. Regular spicy food eaters are also less likely to die from cancer, heart, and respiratory diseases than those who eat spicy foods infrequently.
“The findings are highly novel,” said Lu Qi, associate professor in the Department of Nutrition at Harvard T.H. Chan School of Public Health and Channing Division of Network Medicine, Brigham and Women’s Hospital, and the study’s co-lead author. “To the best of our knowledge, this study is the first reporting a link between spicy food intake and mortality.”
Turning natural landscapes in the Caribbean into urban areas or farmland may increase the risk of people dying from floods and storms, scientists suggest.
In a study published by Scientific Reports last month (8 July), researchers from Anguilla’s health ministry and the Catholic University of Louvain in Belgium investigate which factors make the region more prone to deaths related to these disasters. Out of 20 variables, they found that using a greater proportion of land for agriculture and having a higher percentage of people living in urban areas were consistently linked with deadlier floods and storms.
In summertime, bats are a common feature in the night sky, swooping around backyards to gobble up mosquitos. Bats also help with crops: they act as a natural pesticide by feeding on harmful insects. But these winged mammals are now under threat. As agricultural intensification expands across the world, the conversion of their natural habitats has caused a dramatic decline in population.
The past few weeks have been filled with headlines of crimes against our wildlife from the heartbreaking loss of Cecil the Lion to five more elephant deaths. But justice for our wildlife is on the horizon. The United Nations recently recognized that wildlife crime matters, and it’s on a similar level as human, arms and drug trafficking.
As grasses grew more common in Africa, most major mammal groups tried grazing on them at times during the past 4 million years, but some of the animals went extinct or switched back to browsing on trees and shrubs, according to a study led by the University of Utah.
