Madagascar Grass Atlas
Madagascar has a unique heritage in terms of biodiversity. Its separation from Africa set the backdrop for the unique evolution of its flora and fauna. Its isolated island nature gave rise to high endemism and explosive speciation. Of its estimated 12,000 vascular plant species, 83% are unique to Madagascar (Madagascar... -

Islands in the desert: environmental distribution modelling of endemic flora reveals the extent of Pleistocene tropical relict vegetation in southern Arabia
Background and Aims Southern Arabia is a global biodiversity hotspot with a high proportion of endemic desert-adapted plants. Here we examine evidence for a Pleistocene climate refugium in the southern Central Desert of Oman, and its role in driving biogeographical patterns of endemism. Methods Distribution data for seven narrow-range endemic... -

Unearthing the “Lost” Andean Root Crop “Mauka” (Mirabilis expansa [Ruíz & Pav.] Standl.)
Although recognized as part of the vibrant array of native roots and tubers that support farmers’ livelihoods in the Andean region, the root vegetable “mauka” (Mirabilis expansa (Ruíz & Pav.) Standl.) is little known outside the scattering of communities where it is cultivated and is considered at risk of disappearance....Gendall, H. ; Seminario, J. ; Sørensen, M. ; Theilade, I.

Conservation of the threatened species Pulsatilla vulgaris Mill. (pasqueflower) is aided by reproductive system and polyploidy
Population loss due to habitat disturbance is a major concern in biodiversity conservation. Here we investigate the genetic causes of the demographic decline observed in English populations of P ulsatilla vulgaris and the consequences for conservation. Using ten nuclear microsatellite markers, we compare genetic variation in wild populations with restored... -

Cryobiotechnology for the long-term preservation of oak (Quercus sp.) genetic resources.
Oaks (genus Quercus) are dominant and iconic trees in most European, American, Asian and North African forests, from cool temperate to tropical environments. There are at least 600 species of Quercus globally with high ecological and economical importance. However, 45% of the species evaluated by IUCN are considered threatened, being...Ballesteros, D. ; Nebot, A. ; Pritchard, H.

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... -

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

Lessons from the past and the future of food.
Perspectives from the recent and ancient past are largely underutilized in modern sustainability or food systems studies. However, information about regional crop histories and land use systems through time can add essential value and context to debates concerning future agricultural strategies and food security. In particular, archaeological and anthropological research...Reed, Kelly ; Ryan, Philippa

Mechanisms in mutualisms: a chemically mediated thrips pollination strategy in common elder
The concept of flower-feeding thrips as pollinating insects in temperate regions is rarely considered as they are more frequently regarded to be destructive florivores feeding on pollen and surrounding plant tissue. Combining laboratory and field-based studies we examined interactions between Sambucus nigra (elderflower) and Thrips major within their native range... -

Phylogenomics of Orchidaceae based on plastid and mitochondrial genomes
To advance our knowledge of orchid relationships and timing of their relative divergence, we used 76 protein-coding genes from plastomes (ptCDS) and 38 protein-coding genes from mitochondrial genomes (mtCDS) of 74 orchids representing the five subfamilies and 18 tribes of Orchidaceae, to reconstruct the phylogeny and temporal evolution of the...Li, Yun-Xia ; Li, Zhang-Hai ; Schuiteman, Andre ; Chase, Mark ; Li, Jian-Wu …

The Antiangiogenic Activity of Naturally Occurring and Synthetic Homoisoflavonoids from the Hyacinthaceae (sensu APGII)
Excessive blood vessel formation in the eye is implicated in wet age-related macular degeneration, proliferative diabetic retinopathy, neovascular glaucoma, and retinopathy of prematurity, which are major causes of blindness. Small molecule antiangiogenic drugs are strongly needed to supplement existing biologics. Homoisoflavonoids have been previously shown to have potent antiproliferative activities... -

Molecular phylogeny of the large South American genus Eriosyce (Notocacteae, Cactaceae): Generic delimitation and proposed changes in infrageneric and species ranks
Eriosyce is one of most species‐rich genera within Notocacteae (Cactaceae) harboring a variety of stem and flower morphologies, and fruits with basal abscission. The lack of a well‐sampled molecular phylogeny contributes to the current taxonomic instability of the genus, where its circumscription and infrageneric classification has been questioned.
