aerosol Author: Rubén Soussé Villa is pursuing a PhD in atmospheric chemistry at Barcelona Supercompting Center / Universitat Politècnica de Catalunya Mineral dust aerosols are microscopic rocky particles – for instance, sand – floating in the atmosphere. They are typically windblown from deserts, arid areas and agricultural lands, where they are produced from continued erosion […]
Poland is planning to build a wall along its border with Belarus, primarily to block migrants fleeing the Middle East and Asia. But the wall would also divide the vast and ancient Białowieża Forest, a UNESCO World Heritage site which harbours more than 12,000 animal species and includes the largest remnants of primeval forest that […]
We tend to think Antarctica is isolated and far away – biologically speaking, this is true. But the continent is busier than you probably imagine, with many national programs and tourist operators crisscrossing the globe to get there. And each vessel, each cargo item, and each person could be harbouring non-native species, hitchhiking their way […]
The San Pedro River winds from rainforests in Guatemala through the Yucatan Peninsula in eastern Mexico. There, this peaceful river widens into a series of slow-flowing lakes. Along a remote 50-mile (80-kilometer) stretch, thousands of red mangroves – trees commonly found along tropical coastlines – line the river’s banks and gentle waterfalls. Unlike mangroves elsewhere […]
Is this the first time there has been a fire of this magnitude? If there have been fires like this before, what damage was done to the mountain’s vegetation and how long did it take it to recover? Fires are quite common in the higher areas of Kilimanjaro at the end of the dry seasons […]
Species distribution models (SDM) are computer algorithms that relate species distribution, occurrence or abundance, with information on environmental conditions and spatial characteristics of locations where the species has been, or is suspected to be, found. These models can be used to predict or to have a better understanding of the species distribution, and are widely […]
Author: Teresa E. Gimeno is an Ikerbasque Research Fellow at The Basque Centre for Climate Change One of the expected effects of rising atmospheric CO 2 concentration in the atmosphere is an increase in plant water use efficiency. This is due to the expected enhancement of photosynthesis under future atmospheric CO 2 concentrations, together with […]
Doñana National Park, at the South-western coast of Spain, is known to host several species of wading birds. These piscivorous birds nest in colonies in the neighboring woodlands, formed by cork oaks, close to the marshals where they feed. Ever since the park was opened, the population and nesting of birds, most of them endangered […]
Prolonged exposure to sunlight is not recommended. Even though is really important to synthesize vitamin D which helps us absorbing calcium or phosphate and maintain a mineralized skeleton, the effects of sun´s ultraviolet radiation (mainly UVA and UVB) can be prejudicial in the long term. Main issues may be sunburn (UVB), reduced skin elasticity leading […]
Today is Monday morning and I am going to my laboratory in Niteroi by ferryboat. I took it from the XV Square of Rio de Janeiro. I am looking through the window of the ferryboat and I see one of the most beautiful pictures of the city – the Guanabara Bay (GB). Cariocas (people from […]
