No one-size-fits-all solution to clean GBIF.
Species occurrence records provide the basis for many biodiversity studies. They derive from georeferenced specimens deposited in natural history collections and visual observations, such as those obtained through various mobile applications. Given the rapid increase in availability of such data, the control of quality and accuracy constitutes a particular concern.... -

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.

Diterpenoids from the stem bark of Croton megalocarpoides Friis & M. G. Gilbert.
Five previously undescribed compounds, megalocarpoidolide I (1), megalocarpoidolide J (3), 12-epi-crotonzambefuran A (4), megalocarpoidolide K (5), 1-trans-p-hydroxycoumaroyl–geranylgerani-1-ol (6) were isolated from the stem bark of Croton megalocarpoides Friis & M. G. Gilbert. The known ent-trachyloban-18-ol, megalocarpoidolide B, megalocarpoidolide C (2), megalocarpoidolide H, crotocorylifuran, 7,8-dehydrocrotocorylifuran, 1,2-dehydrocrotocorylifuran-2-one, acetyl aleuritolic acid, lupeol, N-trans-p-coumaroyl-3′,4′-dihydroxyphenylethylamine,... -

Cytotoxic diterpenoids from the leaves and stem bark of Croton haumanianus (Euphorbiaceae).
The leaf extract of Croton haumanianus J. Léonard (Euphorbiaceae) yielded twenty-six compounds, including eight previously reported ent-kauranes and an ent-labdane and eight undescribed ent-kauranes, ent-16R-kauran-17-al, ent-3β-hydroxy-16R-kauran-17-al, ent-16S,17-epoxykauran-19-ol, ent-16S,17-epoxykauran-3β-ol, ent-17-palmityloxykaurane-3β,16β-diol, ent-17-palmityloxykauran-16β-ol, ent-3α,18-cyclokaurane-16β,17-diol and 19-nor-16α,17-dihydroxy-ent-kaur-4(18)-ene and three undescribed ent-clerodanes, dimethyl ent-15,16-epoxy-6β-hydroxy-1,3,13(16),14-clerodatetraen-20,12S-olide-18,19-dioate (saniolide A), dimethyl ent-15,16-epoxy-6β-hydroxy-1,3,13(16),14-clerodatetraen-20,12R-olide-18,19-dioate (12-epi-saniolide A), methyl ent-15,16-epoxy-1,3,13(16),14-clerodatetraen-18,6R:20,12S-diolide-19-oate (saniolide B).

Genome characterization of brugmansia latent virus, a novel tobamovirus.
A novel tobamovirus, brugmansia latent virus (BrLV), was discovered during a study of brugmansia (Brugmansia spp.) in the living collections held at the Royal Botanic Gardens, Kew. Here, we report the complete genome sequence of BrLV, which is 6,397 nucleotides long and contains the four open reading frames (RNA-dependent RNA...Scott-Brown, Alison S. ; D’Elia, Tom ; Devey, Dion S. ; Funderburk, Joseph E. ; Adkins, Scott

Using analytical pyrolysis and scanning electron microscopy to evaluate charcoal formation of four wood taxa from the caatinga of north-east Brazil.
People in north-east Brazil mostly rely on fuelwood and charcoal for domestic energy consumption. Traditionally, four local wood taxa (Mimosa tenuiflora, Mimosa ophthalmocentra, Croton sonderianus and Cenostigma pyramidale) from the caatinga have been selected for this purpose. As the final quality of charcoal is directly related to the charring conditions,... -

α-Amylase and α-glucosidase inhibitors from Zanthoxylum chalybeum Engl. root bark.
A systematic analysis of the root bark of Zanthoxylum chalybeum was conducted to establish the antidiabetic potential of isolated compounds based on its ethnomedicinal use to manage diabetes. Chromatographic separation of alkaloid extracts led to isolation of three undescribed amides, chaylbemide A (1), chalybemide B (2) and chalybemide C (3)...Ochieng, Charles O. ; Nyongesa, Daniel W. ; Yamo, Kevin O. ; Onyango, Joab O. ; Langat, Moses K. …

Born to Eat Wild: An Integrated Conservation Approach to Secure Wild Food Plants for Food Security and Nutrition.
Overlooked in national reports and in conservation programs, wild food plants (WFPs) have been a vital component of food and nutrition security for centuries. Recently, several countries have reported on the widespread and regular consumption of WFPs, particularly by rural and indigenous communities but also in urban contexts. They are...Borelli, Teresa ; Hunter, Danny ; Powell, Bronwen ; Ulian, Tiziana ; Mattana, Efisio …

A new malaria vector in Africa: Predicting the expansion range of Anopheles stephensi and identifying the urban populations at risk.
In 2012, an unusual outbreak of urban malaria was reported from Djibouti City in the Horn of Africa and increasingly severe outbreaks have been reported annually ever since. Subsequent investigations discovered the presence of an Asian mosquito species; Anopheles stephensi, a species known to thrive in urban environments. Since that...Sinka, M.

Two new combinations in Elatostematoides (Urticaceae) for species from Sarawak and Sumatra.
Based on a recently published phylogeny, Elatostematoides is monophyletic and distinct from Elatostema. As more taxa are included in the molecular phylogeny, new combinations will need to be created to accommodate in Elatostematoides species formerly in Elatostema. In the present paper we provide evidence that Elatostema hirtum belongs to Elatostematoides....
