Slash-and-burn agriculture and tropical cyclone activity in Madagascar: Implication for soil fertility dynamics and corn performance

Alexandre Buttler, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Justine Marie Gay des Combes, Thomas Guillaume

On the western coast of Madagascar, the dry tropical forest of Kirindy may disappear in the next 50 years because of its rapid conversion into agricultural land by slash-and-burn cultivation. The slash-and-burn fields are cultivated during 3 years in avera ...

Improving slash-and-burn agriculture in Central Menabe, Madagascar

Justine Marie Gay des Combes

Slash-and-burn agriculture is considered as an important driver of deforestation in the tropics. In Madagascar, a biodiversity hotspot, this type of agriculture particularly threatens the tropical forest cover. On the south-western coast of the island, in ...

Linking historical land use to present vegetation and soil characteristics under slash-and-burn cultivation in Madagascar

Alexandre Buttler, Rodolphe Schlaepfer, Robert Thomas Edmund Mills, Andry Randriamikatra Randrianarison

Aim: In this paper, we link historical land use of cultivated parcels formerly slashed and burnt, with current secondary vegetation and soil characteristics, in the region of evergreen rain forest in Madagascar. Aim is to understand the legacy effect of fo ...

Detection of Convergent Genome-Wide Signals of Adaptation to Tropical Forests in Humans

Matthieu Foll

Tropical forests are believed to be very harsh environments for human life. It is unclear whether human beings would have ever subsisted in those environments without external resources. It is therefore possible that humans have developed recent biological ...

Biodiversity Mapping in a Tropical West African Forest with Airborne Hyperspectral Data

Francesco Giuseppe Miglietta, Qi Chen

Tropical forests are major repositories of biodiversity, but are fast disappearing as land is converted to agriculture. Decision-makers need to know which of the remaining forests to prioritize for conservation, but the only spatial information on forest b ...

Alien plant species distribution in the European Alps: influence of species' climatic requirements

Luca Bragazza

The paper provides the first estimate of the role of abiotic and anthropogenic variables driving both alien plant species richness and composition covering the whole region of the European Alps. To establish and spread in a new area, alien plants must be a ...

Extreme temperature analysis under forest cover compared to an open field

Anthony Christopher Davison, Martine Rebetez, Jacques Ferrez

We analyse air temperature data from 14 sites in Switzerland, each with two weather stations in close proximity, one under a forest canopy and the other in the open. We use the statistics of extremes to investigate how extremely high maximum and extremely ...

Autogenic succession, land-use change, and climatic influences on the Holocene development of a kettle hole mire in Northern Poland

Edward Mitchell, Mariusz Lamentowicz

We reconstructed the Holocene developmental history of a kettle-hole peatland in the Tuchola forest of Northern Poland, using pollen, testate amoebae and plant macrofossils indicators. Our aims were to determine the timing and pattern of autogenic successi ...

Short-term effects of cattle browsing on tree sapling growth in mountain wooded pastures

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountainwooded pasture. Two siz ...
