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.
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.
Researchers find new evidence that large eruptions were responsible for cold temperature extremes recorded since early Roman times
It is well known that large volcanic eruptions contribute to climate variability. However, quantifying these contributions has proven challenging due to inconsistencies in both historic atmospheric data observed in polar ice cores and corresponding temperature variations seen in climate indicators such as tree rings.
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.
El "grindadráp" anual de las Islas Feroe, en el que cientos de ballenas piloto son sacrificados con cuchillos y ganchos, es un espectáculo horrible, escribe David Lusseau. Pero a diferencia de la caza industrial de ballenas, no representa una amenaza para la especie. Pero, ¿es realmente peor que la crianza industrial de animales que habitualmente ignoramos?
The team of scientists, led by Monash University, along with colleagues from the British Antarctic Survey, University of Waikato in New Zealand, and Australian National University, looked at how recent investigations have revealed the continent and surrounding ocean is rich in species. They are also very highly diversified into a variety of distinct ecological regions that differ greatly from each other.
