Living Coordination (Co)Polymerization of Norbornene Derivatives by Using Nickel Catalysts Derived From Bis(1,5‐Cyclooctadiene)nickel(0) and 2,6‐Dihydroxybenzoic Acid

open access: yesJournal of Polymer Science, EarlyView.
The living coordination polymerization of norbornene is achieved using a nickel catalyst derived from Ni(cod)2 and 2,6‐dihydroxybenzoic acid with trityl borate as cocatalyst to produce poly(norbornene) with controllable molecular weights and narrow polydispersity.

Repositories of biocultural diversity: Toward best practices for empowering ethnobotany in digital herbaria

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement As herbaria digitize millions of plant specimens, ethnobotanical information associated with them is becoming increasingly accessible. These biocultural data include plant uses, names, and/or management practices of Indigenous Peoples and Local Communities (IPLCs).

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.
