Hot Coffee: The Identity, Climate Profiles, Agronomy, and Beverage Characteristics of Coffea racemosa and C. zanguebariae.
Climate change poses a considerable challenge for coffee farming, due to increasing temperatures, worsening weather perturbations, and shifts in the quantity and timing of precipitation. Of the actions required for ensuring climate resilience for coffee, changing the crop itself is paramount, and this may have to include using alternative coffee... -

Molecular evidence of species- and subspecies-level distinctions in the rare Orchis patens s.l. and implications for conservation
Characterizing genetic diversity and structure of populations is essential for the effective conservation of threatened species. Orchis patens sensu lato is a narrowly distributed tetraploid species with a disjunct distribution (i.e., Northern Italy, North Africa and the Canary Islands), which is facing a severe decline. In this study, we evaluated...Calevo, Jacopo ; Gargiulo, Roberta ; Bersweden, Leif ; Viruel, Juan ; González-Montelongo, Cristina …

Geographical structure of genetic diversity in Loudetia simplex (Poaceae) in Madagascar and South Africa
Ecologically dominant species are primary determinants of ecosystem function, especially in grassy ecosystems, but the history and biology of grassy ecosystems in Madagascar are poorly understood compared to those of Africa. Loudetia simplex is a C4 perennial grass that is adapted to fire and common to dominant across Africa. It... -

Crop wild phylorelatives (CWPs): phylogenetic distance, cytogenetic compatibility and breeding system data enable estimation of crop wild relative gene pool classification
Enabling food security requires access to a broad range of genetic resources to facilitate crop breeding. This need is increased in a climate change scenario, which will require the production of novel crops adapted to new conditions. However, many major crops have reduced genetic diversity due to the genetic bottlenecks...Viruel, Juan ; Kantar, Michael B ; Gargiulo, Roberta ; Hesketh-Prichard, Peri ; Leong, Nathan …

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
