Convergent Evolution and the Diverse Ontogenetic Origins of Tendrils in Angiosperms

open access: yesFrontiers in Plant Science, 2018
Climbers are abundant in tropical forests, where they constitute a major functional plant type. The acquisition of the climbing habit in angiosperms constitutes a key innovation.

RNA interference in crop protection: opportunities and challenges during the transition to commercialization

open access: yesPest Management Science, Volume 82, Issue 7, Page 5971-5986, July 2026.
RNA interference (RNAi) technologies, host‐induced gene silencing (HIGS) and spray‐induced gene silencing (SIGS), potentially offer sustainable crop protection. However, efficacy, costs, regulatory clarity, and socio‐environmental impacts require further evaluation for broader use.

Is There Life After Death? The Role of Standing Dead Phorophytes in Supporting Tropical Epiphyte Diversity

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
ABSTRACT Global increases in tree mortality from climate change and land‐use are altering forest structures, impacting canopy‐dwelling plants like vascular epiphytes, which depend on host trees (phorophytes). When a phorophyte dies standing, it becomes a snag, the local substrate conditions change and microclimatic exposure may increase, particularly ...

The promise of digital herbarium specimens in large‐scale phenology research

open access: yesNew Phytologist, Volume 251, Issue 2, Page 617-624, July 2026.
Summary The online mobilization of herbaria has made tens of millions of specimens digitally available, revolutionizing investigations of phenology and plant responses to climate change. We identify two main themes associated with this growing body of research and highlight a selection of recent publications exemplifying: investigating phenology at ...

Reconsideraciones taxonómicas en especies mexicanas de Gonolobus (Apocynaceae-Asclepiadoideae)

open access: yesBotan‪ical Sciences
Antecedentes:  En la revisión de Gonolobus para México se observó que G. fuscus, G. luridus y G. tingens carecen de los apéndices estaminales y anillo faucal típicos del género.

Using reflectance spectra and Pl@ntNet to identify herbarium specimens: a case study with Lithocarpus

open access: yesNew Phytologist, Volume 251, Issue 2, Page 800-810, July 2026.
Summary The digitisation of plant collections is bringing large quantities of information into accessible electronic databases. However, in recent decades, traditional taxonomic work in collections has declined, meaning that more specimens are only determined to family or genus, particularly when lacking key identification structures.

Automated extraction of leaf mass per area from digitized herbarium specimens

open access: yesNew Phytologist, Volume 251, Issue 2, Page 896-908, July 2026.
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Specimen‐tailored ‘lived’ climate reveals precipitation onset and amount best predict specimen phenology, but only weakly predict estimated reproduction across a clade

open access: yesNew Phytologist, Volume 251, Issue 2, Page 768-781, July 2026.
Summary Herbarium specimens are widely distributed in space and time, thereby capturing diverse conditions. We reconstructed specimen ‘lived’ climate from knowledge of germination cues and collection dates for 14 annual species in the Streptanthus (s.l.) clade (Brassicaceae) to ask: which climate attributes best explain specimen phenological stage and ...

Digitised herbarium specimen data reveal a climate change‐related trend to an earlier, shorter Canadian Arctic flowering season, and phylogenetic signal in Arctic flowering times

open access: yesNew Phytologist, Volume 251, Issue 2, Page 696-706, July 2026.
Summary The Arctic is experiencing some of the world's most rapid changes in climate. Arctic plant flowering time responses to climate change are understudied. Globally, conflicting evidence exists on whether flowering time responses to temperature are evolutionarily conserved.

Documenting biodiversity with digital data: comparing and contrasting the efficacy of specimen‐based and observation‐based approaches

open access: yesNew Phytologist, Volume 251, Issue 2, Page 721-736, July 2026.
Summary Digitized herbarium specimens and iNaturalist observations provide invaluable plant biodiversity data. Combining these two data sources could create a more holistic representation of local biodiversity; however, understanding biases inherent to each is critical to determine how to best combine and utilize these data.
