Buffering effects of soil seed banks on plant community composition in response to land use and climate Instituut voor Natuur- en Bosonderzoek

Jan Plue, Hans Van Calster, Inger Auestad, Sofía Basto, Renée M. Bekker, Hans Henrik Bruun, Richard Chevalier, Guillaume Decocq, Ulf Grandin, Martin Hermy, et al.
Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help plant communities to resist or at least postpone the detrimental impact of global changes. This study investigates the potential for soil seed banks to achieve this. Location Europe. ...

Modelling the evolution of Djankuat Glacier, North Caucasus, from 1752 until 2100 CE Vrije Universiteit Brussel

Yoni Verhaegen, Philippe Huybrechts, Oleg Rybak, Victor Popovnin
We use a numerical flow line model to simulate the behaviour of the Djankuat Glacier, a World Glacier Monitoring Service reference glacier situated in the North Caucasus (Republic of Kabardino-Balkaria, Russian Federation), in response to past, present and future climate conditions (1752–2100 CE). The model consists of a coupled ice flow–mass balance model that also takes into account the evolution of a supraglacial debris cover. After ...

Antimony leaching from soils and mine waste from the Mau Due antimonymine, North-Vietnam KU Leuven

Valérie Cappuyns, Axelle Van Campen, Jillian Helser
Antimony (Sb) is an element with a growing concern due to its toxicity, but also because of its criticality. While the impact of Sb mining is documented in literature from China and Europe, still little data is available concerning the environmental impact of Sb mining in Vietnam. This paper presents the results of an exploratory study of mine waste and soil samples from the Mau Due mine (North Vietnam). The chemical and mineralogical ...

Trace elements leaching from Pb-Zn mine waste (Plombières, Belgium) and environmental implications KU Leuven

Jillian Helser, Valérie Cappuyns
The geochemical and mineralogical characterization of mine waste provides essential information to understand the environmental and health impacts and to adequately manage present and historical mine waste sites. In the present study, mine waste samples from a former Zn-Pb mining site were subjected to different types of leaching tests, an in-vitro bioaccessibility test, and a mineralogical analysis. The samples were characterized by elevated ...

Measuring soil evaporation from a cropped land in the semi-arid Makanya catchment, Northern Tanzania Vrije Universiteit Brussel

Kobusinge Aloys Nyabwisho, Jan Diels, Fredrick Casian Kahimba, Ann Van Griensven

Estimating soil water loss from cropped land is vital for sustainable management of water resources in semi-arid and hot regions. Soil evaporation (Es) is an important process in these regions but hard to quantify. The study aimed at quantifying Es in maize field under three treatments using micro-lysimeters (MLs). It also aims to identify sources of challenges in the method. The treatments were; flat cultivation with mulching (FCM), without ...

Complex Interactions Between Large Igneous Province Emplacement and Global‐Temperature Changes During the Cenomanian‐Turonian Oceanic Anoxic Event (OAE 2) Vrije Universiteit Brussel

Lawrence Percival, Niels van Helmond, David Selby, Steven Goderis, Philippe Claeys
Super greenhouse temperatures at the onset of the Cenomanian‐Turonian oceanic anoxic event (OAE 2) have been widely linked with large igneous province (LIP) volcanic activity. However, the extent to which volcanism influenced subsequent climate changes throughout OAE 2, such as global cooling during the Plenus Cold Event (PCE) early in the OAE, and the subsequent return to very warm conditions through the second part of the crisis remain less ...
