Decrease in CO2 efflux from northern hardwater lakes with increasing atmospheric warming
Boreal lakes are biogeochemical hotspots that alter carbon fluxes by sequestering particulate organic carbon in sediments1, 2 and by oxidizing terrestrial dissolved organic matter to carbon dioxide (CO2) or methane through microbial processes3, 4. At…
Defining the Anthropocene
Time is divided by geologists according to marked shifts in Earth’s state. Recent global environmental changes suggest that Earth may have entered a new human-dominated geological epoch, the Anthropocene. Here we review the historical genesis of the…

Contents: What Is a Desert; How the Atmosphere Influences Aridity; Where Deserts Form; Types of Deserts; Desert Features; Eolian Processes; Types of Dunes; Remote Sensing of Arid Lands; Mineral Resources in Deserts; Desertification.

The bioeconomy and
future rural pathways
Expectations and contradictions in the rural, played out through small-scale farming, the pervasive nature of globalization, discourses of food security, new productivism and escalation in global land grabs have been shown in previous reports to…
Drought impact on forest carbon dynamics and fluxes in Amazonia
Severe drought in a tropical forest ecosystem suppresses photosynthetic carbon uptake and plant maintenance respiration, but growth is maintained, suggesting that, overall, less carbon is available for tree tissue maintenance and defence, which may…
Ecosystems: Time to model all life on Earth
The authors discuss the importance for international authorities such as the Intergovernmental Platform on Biodiversity and Ecosystem Services to simulate the physics and chemistry of the ecosystem to better understand the climate system. They…
Erosion of organic carbon in the Arctic as a geological carbon dioxide sink
Robert G. Hilton, Valier Galy, Jérôme Gaillardet, Mathieu Dellinger, Charlotte Bryant, Matt O'Regan, Darren R. Gröcke, Helen Coxall, Julien Bouchez & Damien Calmels
Evolution of endemism on a young tropical mountain
Investigating the evolutionary origins of montane biodiversity by sampling the entire biota from a single mountain, Mount Kinabalu in Borneo, allows for a better understanding not only of the origins of endemism, but also of this biota’s forecasted…
Fundamentals of Physical Geography, 2nd Edition
The Fundamentals of Physical Geography (2nd Edition) online textbook describes an area of knowledge within Geography known as Physical Geography. The textbook contains over three hundred pages of information and more than four hundred 2-D…
Genetic evidence for two founding populations of the Americas
Previous genetic studies have suggested that the Americas were peopled by a single founding population of Eurasian origin, but a genome-wide study of 30 Native American groups shows that Amazonian Native Americans also have a second source of…
Geographies of race and ethnicity 1
In this report I compare two forms of racism: white privilege and white supremacy. I examine how they are distinct and can be seen in the environmental racism arena. I argue that within US geographic scholarship white privilege has become so…
Geography, Globalization, and the Problematic of Area Studies
There has been considerable debate about the challenges and opportunities posed for geographical scholarship by globalization. In similar contexts, however, the discipline's relationship to area studies merits careful review and reworking. Three…

Aleksander Stamboliski and the Bulgarian Contract
Bulgaria suffered a swift and devastating defeat in the First World War, due, G.D. Sheppard argues, to its peasant leader-in-waiting’s shrewd use of…
