Various ways to determine rational number size: An exploration across primary and secondary education KU Leuven
Understanding rational numbers is a complex task for primary and secondary school students. Previous research has shown that a possible reason is students’ tendency to apply the properties of natural numbers (inappropriately) when they are working with rational numbers (a phenomenon called natural number bias). Focusing on rational number comparison tasks, recent research has shown that other incorrect strategies such as gap thinking or reverse ...
National or European Agents? An Exploration into the Representation Behaviour of the EU Member States at the UN Security Council KU Leuven
Nationale of Europese Agenten?Een Exploratie van het Vertegenwoordingsgedrag van de Europese Lidstaten in de VN-VeiligheidsraadDit werk exploreert de manifestatie van EU actorness in de VN-Veiligheidsraad (VNVR), zowel empirisch als theoretisch. Het begrip actorness verwijst naar de capaciteit van de EU om extern op te treden en is uitgegroeid tot een van de basisconcepten in de literatuur over het buitenlands beleid van de EU. Ook voor de ...
Woodland management as major energy supply during the early industrialization : a multiproxy analysis in the northwest European lowlands Universiteit Gent
Wood and charcoal were key sources of energy during early industrialization in Europe (18th century), preceding the large-scale exploitation of fossil coal. Past timber harvesting implied land transformation and woodland resources management. Therefore, relict charcoal kilns and historical documents of forest management are important sources of information about past woodland composition and structure. However, ancient charcoal kilns are poorly ...
Western lowland gorilla density and nesting behavior in a Gabonese forest logged for 25 years: implications for gorilla conservation Koninklijke Maatschappij voor Dierkunde van Antwerpen
Impacts of logging and hunting on western lowland gorilla ( Gorilla gorilla gorilla) populations and consequences for forest regeneration . A review Koninklijke Maatschappij voor Dierkunde van Antwerpen
Timber exploitation is rapidly expanding throughout the Congo Basin. Forest areas assigned to timber harvesting have sharply expanded over the decades and logging concessions now largely overlap with the range of western lowland gorilla (Gorilla gorilla gorilla Savage Wyman, 1847). However this species, which is considered as critically endangered by IUCN, could play an essential role in maintaining the structure and composition of tropical ...
Short term impact of selective logging on a western lowland gorilla population Koninklijke Maatschappij voor Dierkunde van Antwerpen
Selective timber production is implemented over a large proportion of the world’s tropical forests. Within these forest ecosystems, the frugivore community contributes important ecological services through animal-mediated seed dispersal. However, there is no clear understanding of the impacts of logging on wildlife or of the extent to which seed dispersal is preserved in logged forests. Given its tendency for nesting in light gaps, the western ...
Old trees: Extraction, Conservation Can Coexist KU Leuven
Letters Because large old trees are essential for forest ecosystem integrity and biodiversity, timber extraction in managed forests should preferentially be concentrated where large old trees are least likely to develop ("Global decline in large old trees," D. B. Lindenmayer et al., Perspectives, 7 December 2012, p. 1305). However, timber extraction and the conservation of large old trees are not necessarily mutually exclusive. Current forest ...
