Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1042-1056, July 2026.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

Using large language models to automate herbarium specimen transcription: A case study at the Missouri Botanical Garden

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1068-1075, July 2026.
Biological specimens housed in natural history collections are indispensable resources for documenting where species occur and how they have changed through time, and are thus vital for combating biodiversity loss. Digitization of these collections promises to make these critical resources globally available.

Individual Trees Respond to 40 Years of Climate Change Through Leaf Functional Trait Acclimation

Global Change Biology, Volume 32, Issue 7, July 2026.
We measured leaf traits from historic and contemporary herbarium specimens collected from the same individual trees in the southern Peruvian Amazon and compared trait changes to local changes in climate which included increasing temperature, decreasing precipitation, and increasing [CO2]. We found significant decreases in leaf mass per area (LMA), leaf

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Harnessing the benefits of herbarium specimen digitisation for inferring recent and ongoing plant extinctions

New Phytologist, Volume 251, Issue 2, Page 677-688, July 2026.
Summary Evidence for the ongoing biodiversity crisis rests on assessment of a small fraction of described species, with major knowledge gaps for most organisms, including plants. Here, we highlight how digitised herbarium specimens can be used to accelerate and improve estimates of recent and ongoing plant extinctions.

Tree Cover and Temperature Shape the Distribution of Epiphytic Pleurozia in Asia: Forest Havens in a Warming Climate

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study uses an optimized MaxEnt model to predict the potential distribution of Pleurozia across Asia under current and future climate scenarios. Our results show that evergreen broadleaf forest cover, temperature annual range, mean diurnal range, and altitude are the key environmental determinants, and that suitable habitats are projected to expand
