Placing unprecedented recent fir growth in a European-wide and Holocene-long context

Jed Oliver Kaplan

Forest decline played a pivotal role in motivating Europe's political focus on sustainability around 35 years ago. Silver fir (Abies alba) exhibited a particularly severe dieback in the mid-1970s, but disentangling biotic from abiotic drivers remained chal ...

Continental-Scale Footprint of Balancing and Positive Selection in a Small Rodent (Microtus arvalis)

Matthieu Foll

Genetic adaptation to different environmental conditions is expected to lead to large differences between populations at selected loci, thus providing a signature of positive selection. Whereas balancing selection can maintain polymorphisms over long evolu ...

The Limits to Parapatric Speciation: Dobzhansky-Muller Incompatibilities in a Continent-Island Model

Claudia Bank

How much gene flow is needed to inhibit speciation by the accumulation of Dobzhansky-Muller incompatibilities (DMIs) in a structured population? Here, we derive these limits in a classical migration-selection model with two haploid or diploid loci and unid ...

Water use by Sclerocarya birrea Agroforestry Trees in Sudanian Savanna: Application of Wireless Sensor Networks

Natalie Claire Ceperley

Small scale rain fed agriculture is the primary livelihood for a large part of the population of Burkina Faso. Regional climate change means that this population is becoming increasingly vulnerable. Additionally, as natural savanna is converted for agricul ...

The origin and fate of atmospheric moisture over continents

Bettina Schaefli

There has been a long debate on the extent to which precipitation relies on terrestrial evaporation (moisture recycling). In the past, most research focused on moisture recycling within a certain region only. This study makes use of new definitions of mois ...

Constructing the desert. Hotel and coach station (Ouarzazate, Maroc)

Pietro Berta, Adèle Moret

Desertification process keeps on expanding, particularly on the African continent, arid areas cover one third of the surface. At the same time, the world human population increases exponentially. For these reasons, it is important to keep on exploiting the ...

Zircon SHRIMP dating of granite from Qaidamshan, NW China

Anders Meibom

Zircon SHRIMP dating from Qaidamshan granite shows that the granite age is 446 Ma, similar to that of eclogite in the LW belt. We think that both granite and eclogite may be formed at different stages during tectonic evolution of this area. Together with o ...
