Farmers’ decisions and determinants of crop rotations with lupin (Lupinus spp): The case of West Amhara Region, Ethiopia
Using lupin as a break crop and for soil fertility improvement is one of the practices to enhance productivity and improve soil fertility in Ethiopian conditions. However, the use of this practice by smallholder farmers is limited. Therefore, the major objective of this study was to empirically examine factors influencing...Teferra, B ; Yeheyis, L ; Nelson, M ; Taylor, J ; McNaughton, D …

Evolutionary history of the Pasque-flowers (Pulsatilla, Ranunculaceae): Molecular phylogenetics, systematics and rDNA evolution
Pulsatilla (Anemoneae, Ranunculaceae) is sister to Anemone s.s. and contains ca 40 perennial species of considerable horticultural and medical importance. We sequenced 31 of those species, plus nine subspecies, two cultivars and six outgroups, for two nuclear regions (high-copy nrITS and low-copy MLH1) and three plastid regions (rbcL, accD–psaI, trnL...Sramkó, G ; Laczkó, L ; Volkova, P ; Bateman, R ; Mlinarec, J

Exploring At Second-Hand: Separating the Editor from the Traveller in Soeteboom’s Version of Van West-Zanen’s Sojourn in Mauritius in 1602
Willem van West-Zanen’s account of visiting Mauritius with Hans Schuurmans’s fleet of five ships on their return journey from Java to Amsterdam in 1602, is translated in full for the first time. Numerous Dodos were caught and eaten by the crews, as was much other wildlife.Cheke, Anthony ; Beentje, Henk

Ethnobotany of Aloe L. (Asphodelaceae) in Tanzania
The genus Aloe (Asphodelaceae) is well known in Tanzania for its medicinal uses, yet its ethnobotany has not previously been systematically studied in the region. To document the indigenous knowledge of Aloe species, data were collected using semi-structured interviews from 180 respondents of different gender and age groups at four...Amir, H ; Grace, O ; Wabuyele, E ; Manoko, M

Epidermal patterning and stomatal development in Gnetales
The gymnosperm order Gnetales, which has contentious phylogenetic affinities, includes three extant genera (Ephedra, Gnetum, Welwitschia) that are morphologically highly divergent and have contrasting ecological preferences: Gnetum occupies mesic tropical habitats, whereas Ephedra and Welwitschia occur in arid environments. Leaves are highly reduced in Ephedra, petiolate with a broad lamina...Rudall, Paula ; Rice, Callie

Enhancement of conservation knowledge through increased access to botanical information
Herbarium specimens are increasingly recognized as an important resource for conservation science and virtual herbaria are making specimens freely available to a wider range of users than ever before. Few virtual herbaria are designed with conservation use as a primary driver. Exceptionally, Brazil's Reflora Virtual Herbarium (RVH) was created to...Canteiro, Cátia ; Barcelos, Laísa ; Filardi, Fabiana ; Forzza, Rafaela ; Green, Laura …

Environmental stress, future climate, and germination of myracrodruon urundeuva seeds
Myracrodruon urundeuva, a native species from the Brazilian Caatinga, is widely distributed across its endemic region, where it also plays an essential socioeconomic role. The objective of this study was to evaluate the influence of environmental stress on the germination of M. urundeuva seeds harvested in different years (2010 to...De, Oliveira ; Santos da Silva, F ; Nascimento, Araujo ; Campos Da Costa, D ; Vieira Gomes, S …

Enset in Ethiopia: a poorly characterized but resilient starch staple.
Enset (Ensete ventricosum, Musaceae) is an African crop that currently provides the staple food for approx. 20 million Ethiopians. Whilst wild enset grows over much of East and Southern Africa and the genus extends across Asia to China, it has only ever been domesticated in the Ethiopian Highlands. Here, smallholder... -

Dynamics of intracellular mannan and cell wall folding in the drought responses of succulent Aloe species
Plants have evolved a multitude of adaptations to survive extreme conditions. Succulent plants have the capacity to tolerate periodically dry environments, due to their ability to retain water in a specialized tissue, termed hydrenchyma. Cell wall polysaccharides are important components of water storage in hydrenchyma cells. However, the role of...Ahl, Louise ; Mravec, Jozef ; Jørgensen, Bodil ; Rudall, Paula ; Rønsted, Nina …

Embolism resistance in petioles and leaflets of palms
Hydraulic studies are currently biased towards conifers and dicotyledonous angiosperms; responses of arborescent monocots to increasing temperature and drought remain poorly known. This study aims to assess xylem resistance to drought-induced embolism in palms.We quantified embolism resistance via P50 (xylem pressure inducing 50% of embolism or loss of hydraulic conductivity)...Emilio, Thaise ; Lamarque, Laurent ; Torres-Ruiz, José ; King, Andrew ; Charrier, Guillaume …
