Interactions between plant genome size, nutrients and herbivory by rabbits, molluscs and insects on a temperate grassland
Angiosperm genome sizes (GS) vary ca 2400-fold. Recent research has shown that GS influences plant abundance, and plant competition. There are also tantalizing reports that herbivores may select plants as food dependent on their GS. To test the hypothesis that GS plays a role in shaping plant communities under herbivore...Guignard, Maïté ; Crawley, Michael ; Kovalenko, Dasha ; Nichols, Richard ; Trimmer, Mark …

Indigenous knowledge networks in the face of global change
Indigenous communities rely extensively on plants for food, shelter, and medicine. It is still unknown, however, to what degree their survival is jeopardized by the loss of either plant species or knowledge about their services. To fill this gap, here we introduce indigenous knowledge networks describing the wisdom of indigenous...Cámara-Leret, R ; Fortuna, M ; Bascompte, J

INDEL variation in the regulatory region of the major flowering time gene LanFTc1 is associated with vernalization response and flowering time in narrow-leafed lupin (Lupinus angustifolius L.)
Narrow‐leafed lupin (Lupinus angustifolius L.) cultivation was transformed by 2 dominant vernalization‐insensitive, early flowering time loci known as Ku and Julius (Jul), which allowed expansion into shorter season environments. However, reliance on these loci has limited genetic and phenotypic diversity for environmental adaptation in cultivated lupin. We recently predicted that...Taylor, Candy ; Kamphuis, Lars ; Zhang, Weilu ; Garg, Gagan ; Berger, Jens …

Incorporating evolutionary history into conservation assessments of a highly threatened group of species, South African Dioscorea (Dioscoreaceae)
In an era of increasing threat most species of plant still lack an assessment of extinction risk or an understanding of priority for conservation. Evolutionary distinctiveness (ED) has been used in conjunction with extinction risk to prioritise species for conservation. We apply this approach to an economically important group of...Hills, R ; Bachman, S ; Forest, Félix ; Moat, Justin ; Wilkin, Paul

Homoisoflavonoids and cardenolides from cultivated Ornithogalum species: Ornithogalum dubium Houtt. and Ornithogalum ponticum ‘Sochi’
Three new homoisoflavonoids, (3R)-3,5-dihydroxy-7-methoxy-3-(4′-hydroxybenzyl)-4-chromanone, 4, and its 5-O-β-D-glucopyranoside and 5-O-β-D-gentiobiose derivatives, 5 and 6, along with the known homoisoflavonoids, (3S)-5-hydroxy-7-methoxy-3-(4-methoxybenzyl)-4-chromanone, 1, (3R)-5-hydroxy-7-methoxy-3-(4-methoxybenzyl)-4-chromanone (2) and (3S)-5-hydroxy-7-methoxy-3-(4-hydroxybenzyl)-4-chromanone, 3, were isolated from the bulbs of Ornithogalum dubium Houtt. In addition, three known cardenolides, 3β-(O-α-L-rhamnoside)-5β,14β-dihydroxy-19-oxocardenolide 7, 3β-(O-α-L-rhamnoside)-5β,11α,14β-trihydroxy-19-oxocardenolide, 8 and 3β-(O-α-L-rhamnoside)-5β,11α,14β,19-tetrahydroxycard-20(22)-enolide, 9, were isolated from...Langat, L ; Langat, Moses K. ; Mulholland, D

Human activity is altering the world’s zoogeographical regions
Zoogeographical regions, or zooregions, are areas of the Earth defined by species pools that reflect ecological, historical and evolutionary processes acting over millions of years. Consequently, researchers have assumed that zooregions are robust and unlikely to change on a human timescale. However, the increasing number of human-mediated introductions and extinctions...Bernardo-Madrid, Rubén ; Calatayud, Joaquín ; González-Suárez, Manuela ; Rosvall, Martin ; Lucas, Pablo …

Harnessing the potential of integrated systematics for conservation of taxonomically complex, megadiverse plant groups
The value of natural history collections for conservation science research is increasingly recognized, despite their well-documented limitations in terms of taxonomic, geographic, and temporal coverage. Specimen-based analyses are particularly important for tropical plant groups for which field observations are scarce and potentially unreliable due to high levels of diversity-amplifying identification...Nic Lughadha, Eimear ; Graziele Staggemeier, Vanessa ; Vasconcelos, Thais ; Walker, Barnaby ; Canteiro, Cátia …

Hydrothermal thresholds for seed germination in winter annual forbs from old-field Mediterranean landscapes
Under Mediterranean climates with dry-hot summers and cool-wet winters, many forbs with potential for habitat restoration are winter annuals, but there is little information about their germination. We performed laboratory germination experiments on 13 ruderal dicots native to Andalusia (southern Spain). We measured the germination of recently harvested seeds from...Frischie, S ; Fernández-Pascual, E ; Ramirez, C ; Toorop, P ; González, M …

High extinction risk for wild coffee species and implications for coffee sector sustainability
Wild coffee species are critical for coffee crop development and, thus, for sustainability of global coffee production. Despite this fact, the extinction risk and conservation priority status of the world’s coffee species are poorly known. Applying IUCN Red List of Threatened Species criteria to all (124) wild coffee species, we...Davis, Aaron ; Chadburn, Helen ; Moat, Justin ; O’Sullivan, Robert ; Hargreaves, Serene …
