For antagonists and mutualists: the paradox of insect toxic secondary metabolites in nectar and pollen
The plant kingdom produces an extraordinary diversity of secondary metabolites and the majority of the literature supports a defensive ecological role for them, particularly against invertebrate herbivores (antagonists). Plants also produce secondary compounds in floral nectar and pollen and these are often similar to those produced for defense against invertebrates...Stevenson, Philip C.

Dendrobium annulatum (Orchidaceae: Epidendroideae), a new species of Dendrobium section Grastidium from Indonesian New Guinea
The second largest genus of Orchidaceae, Dendrobium Swartz (1799: 82), has close to 1600 accepted species names (Govaerts et al. 2019). Indonesia is particularly rich in species of Dendrobium, with, for example, 114 and 53 species recorded from Sumatra and Java, respectively (Comber 1990, 2003). However, this pales in comparison...Juswara, Lina S. ; Schuiteman, André ; Champion, Jeffrey

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. Specimens of...Guerrero, Pablo C. ; Walter, Helmut E. ; Arroyo, Mary T. K. ; Peña, Carol M. ; Tamburrino, Italo …

The climatic challenge: Which plants will people use in the next century?
More than 31,000 useful plant species have been documented to fulfil needs and services for humans or the animals and environment we depend on. Despite this diversity, humans currently satisfy most requirements with surprisingly few plant species; for example, just three crops – rice, wheat and maize – comprise more... -

Potential adaptive strategies for 29 sub-Saharan crops under future climate change
Climate change is expected to severely impact cultivated plants and consequently human livelihoods, especially in sub-Saharan Africa (SSA). Increasing agricultural plant diversity (agrobiodiversity) could overcome this global challenge given more information on the climatic tolerance of crops and their wild relatives. Using >200,000 worldwide occurrence records for 29 major crops... -

Thermal thresholds for seed germination in Mediterranean species are higher in mountain compared with lowland areas
Each taxon is characterized by a temperature range over which seed germination is possible and this may vary in space and time in relation to climate and ecological conditions. We used thermal modelling to test the hypothesis that thermal thresholds for seed germination can predict germination timing of Mediterranean species...Picciau, R. ; Pritchard, Hugh ; Mattana, E. ; Bacchetta, G.

The Manokwari Declaration: Challenges ahead in conserving 70% of Tanah Papua’s forests
The Manokwari Declaration is an unprecedented pledge by the governors of Indonesia’s two New Guinea provinces to promote conservation and become SE Asia’s new Costa Rica. This is an exciting, yet challenging endeavour that will require working on many fronts that transcend single disciplines. Because Indonesian New Guinea has the...Cámara-Leret, Rodrigo ; Schuiteman, Andre ; Utteridge, Timothy ; Bramley, Gemma ; Deverell, Richard …

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...
