Macroevolutionary patterns in seed component mass and different evolutionary trajectories across seed desiccation responses.
Seed coat and seed reserve show substantial mass variation, play different roles in plant life strategies and are shaped by different selective forces. However, remarkably little is known about the macroevolution of the relative allocation in seed components and its influence on important ecophysiological processes. Using phylogenetic comparative methods and...Chen, Si‐Chong ; Wu, La‐Mei ; Wang, Bo ; Dickie, John B.

Hibiscus fabiana sp. nov. (Malvaceae) from the Guinea Highlands (West Africa)
Hibiscus fabiana Cheek (sect. Furcaria, Malvaceae) is described from the Guinea Highlands of West Africa, and its taxonomic affinities and ecology are considered. Hibiscus fabiana has previously been confused with H. rostellatus but has red fleshy calyx ribs (vs not red and non-fleshy), the calyx surface is glabrous apart...Cheek, M. ; Haba, P.K. ; Cisse, S.

Plant dispersal strategies of high tropical alpine communities across the Andes
Dispersal is a key ecological process that influences plant community assembly. Therefore, understanding whether dispersal strategies are associated with climate is of utmost importance, particularly in areas greatly exposed to climate change. We examined alpine plant communities located in the mountain summits of the tropical Andes across a 4000 km... -

Convergent molecular evolution among ash species resistant to the emerald ash borer
Recent studies show that molecular convergence plays an unexpectedly common role in the evolution of convergent phenotypes. We exploited this phenomenon to find candidate loci underlying resistance to the emerald ash borer (EAB, Agrilus planipennis), the United States’ most costly invasive forest insect to date, within the pan-genome of ash...Kelly, Laura J. ; Plumb, William J. ; Carey, David W. ; Mason, Mary E. ; Cooper, Endymion D. …

Microsatellite marker development in the crop wild relative Linum bienne using genome skimming
Premise: Nuclear microsatellite markers were developed for Linum bienne, the sister species of the crop L. usitatissimum, to provide molecular genetic tools for the investigation of L. bienne genetic diversity and structure. Methods and Results: Fifty microsatellite loci were identified in L. bienne by means of genome skimming, and 44...Landoni, Beatrice ; Viruel, Juan ; Gómez, Rocio ; Allaby, Robin G. ; Brennan, Adrian C. …

Monitoring Biodiversity and Ecosystem Services in Colombia's High Andean Ecosystems: Toward an Integrated Strategy
There is growing consensus that biodiversity losses resulting from global change profoundly affects ecosystem services and human welfare. However, biodiversity and ecosystem processes are commonly monitored independently and on spatiotemporal scales inadequate to inform decision-making. The high Andean ecosystems of Colombia, extending from high Andean forests and páramos to glacier...Llambí, Luis D. ; Becerra, María Teresa ; Peralvo, Manuel ; Avella, Andrés ; Baruffol, Martín …

Lost and Found: Coffea stenophylla and C. affinis, the Forgotten Coffee Crop Species of West Africa.
Coffea arabica (Arabica) and C. canephora (robusta) almost entirely dominate global coffee production. Various challenges at the production (farm) level, including the increasing prevalence and severity of disease and pests and climate change, indicate that the coffee crop portfolio needs to be substantially diversified in order to ensure resilience and...Davis, Aaron P. ; Gargiulo, Roberta ; Fay, Michael F. ; Sarmu, Daniel ; Haggar, Jeremy

Comparing essential oils from Australia's ‘Victorian Christmas Bush’ (Prostanthera lasianthos Labill., Lamiaceae) to closely allied new species: Phenotypic plasticity and taxonomic variability
Prostanthera lasianthos (Lamiaceae) is commonly referred to as the ‘Victorian Christmas Bush’, a name that derives from the floral display it gives in the Christmas period. However, botanists recognise P. lasianthos as a heterogeneous species aggregate that includes several putative new species that are confined to disjunct locations. Recently one...Sadgrove, Nicholas John

Virotia azurea (Proteaceae: Macadamieae), a striking new species endemic to New Caledonia and notes on V. francii and V. leptophylla
Virotia azurea H.C. Hopkins & Pillon (Proteaceae), the seventh species in the endemic genus Virotia L.A.S. Johnson & B.G. Briggs from New Caledonia is described and illustrated. A distribution map and preliminary conservation assessment are provided. This new species occurs principally on non-ultramafic substrates in a restricted area of central...Hopkins, Helen C.F. ; Pillon, Yohan
