Extensive green roofs in context: An open and multidisciplinary perspective on green roofs and their practical issues KU Leuven
The 21st century will be characterized by urbanization, as the number of people living in cities will continue to rise. As cities continue to expand, their impact on the environment does as well. Rising urban temperatures, increased risk of flooding and the loss of habitat of local plants and animals are just a few of the problems with which we will be faced. Nature, however, can also deliver solutions to these issues by providing benefits (or ...
Plastid phylogenomics of the Sansevieria Clade of Dracaena (Asparagaceae) resolves a recent radiation Universiteit Gent Plantentuin Meise / Agentschap Plantentuin Meise
Best known as low maintenance houseplants, sansevierias are a diverse group of flowering plants native to Africa, Madagascar, the Arabian Peninsula, and the Indian subcontinent. Traditionally recognised as a distinct genus, Sansevieria was recently merged with the larger genus Dracaena based on molecular phylogenetic data. Within the Sansevieria Clade of Dracaena, taxonomic uncertainties remain despite attempts to unravel the relationships ...
Contribution of corticular photosynthesis to bud development in African baobab (**Adansonia digitata** L.) and Castor bean (**Ricinus communis** L.) seedlings Universiteit Antwerpen
The African baobab (Adansonia digitata L.) and castor bean (Ricinus communis L.) are drought resistant green-stemmed succulent plants which grow in the arid and semi-arid regions of Africa. Photosynthesis in the stems of green-stemmed plants is known to contribute to plant carbon gain especially during leafless periods. To study the contribution of stem photosynthesis in stem succulent plants, the height and stem diameter of baobab and castor ...
Field body temperatures, activity levels and opportunities for thermoregulation in an extreme microhabitat specialist, the girdled lizard (Cordylus macropholis) Instituut voor Natuur- en Bosonderzoek
The girdled lizard Cordylus macropholis inhabits semi-desert areas along the west coast of South Africa. Unlike many other small diurnal lizards living in open habitats, it exhibits extreme low levels of above-ground activity and does not show overt thermoregulatory behaviours, such as basking or shuttling. It has an extreme low movement rate and confines routine activity to the microhabitat of the succulent Euphorbia caput-medusae. We document ...
Endangered Species: 50% of IUCN Euphorbia species in the ex situ collection at Meise. Plantentuin Meise / Agentschap Plantentuin Meise
Objective 2 target 8 of the Global Strategy for Plant Conservation 2011-2020 aims to secure 75% of threatened plants species in ex situ collections. The Botanic Garden Meise contributes to this target by investing in conservation relevant collections. In 2015, the garden reached its conservation goal to secure 50% of the 199 Euphorbia species assessed by IUCN as vulnerable, endangered or critically endangered by at least one accession per taxon. ...
Improvised Hand Injury Treatment Using Traditional Veterinary Medicine in Ethiopia KU Leuven
In remote wilderness environments, local people with traditional knowledge of medicinal plants are potentially important first-line health care providers. We present a case of a 31-year-old man who fell off a horse while trekking through a remote mountain landscape in Ethiopia and sustained blunt force trauma to the hand. A local mountain hut keeper examined the patient’s hand and used heated leaves of the succulent plant Kalanchoe petitiana to ...
Vegetation development on different extensive green roof types in a Mediterranean and temperate maritime climate KU Leuven
© 2015 Elsevier B.V. Green roofs offer a way to improve ecosystem services in urban areas. In the Mediterranean, specialized companies are still unfamiliar with green roof installation because they consider dry conditions and appropriate plant selection as obstacles. Also in a temperate maritime climate, green roof design and vegetation composition need to be adapted to account for the projected climate changes, including an increase in ...
A preliminary overview of the diversity of species of Agave (Century Plant) as potentially invasive species in the Canary Islands Plantentuin Meise / Agentschap Plantentuin Meise
The Canary Islands have an extraordinary endemic flora that includes a high number of often tiny succulents that are adapted to the local xeric climate. In recent times, however, the composition of the local succulent flora dramatically changed: some of the native species are at risk and are increasingly replaced by taller, aggressive alien succulents, from families such as Cactaceae and Agavaceae. Agave L. is a New World genus, growing ...
