Indumento y tricomas en la caracterización de un grupo de nueve especies del género Mortoniodendron (Tiliaceae) Indument and trichomes in the characterization of a group of nine species of Mortoniodendron (Tiliaceae)

open access: yesRevista Mexicana de Biodiversidad, 2006
Se estudió el indumento y la morfología de los tricomas del envés de las hojas y del endocarpo de 9 especies del género Mortoniodendron (Tiliaceae). Se establece el tipo de indumento y de tricomas según la forma, simetría, tamaño y densidad, mediante ...

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, EarlyView.
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 ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

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

open access: yesNew Phytologist, EarlyView.
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.

PEP725: 15 years of driving European and global phenology science

open access: yesNew Phytologist, EarlyView.
Summary Phenology – the timing of seasonal biological events – is a sensitive indicator of climate change and ecosystem dynamics. Long‐term, broad‐scale phenological data are crucial for understanding and predicting plant responses to environmental change.

Population genomic signatures of founding events in autonomously self‐fertilizing plants: a test with Impatiens capensis

open access: yesNew Phytologist, EarlyView.
Summary Autonomously self‐fertilizing plants possess disproportionate abilities to found populations. Viewed from the metapopulation perspective, founding events should be frequent in such plants, but the intensity and timing of bottlenecks and recovery should vary among populations.

Landless peasants, soilless cultivation: British agricultural experimentation and intervention in post‐independence Iraq (1932–1958)

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 603-610, March 2026.
‘Greening’ is often depicted as an inherently benevolent practice, turning arid stretches of land into arable and fertile plots. However, by considering a longer history of place and taking archival records into account, such transformations are rendered more complex and, often, more fraught.

Descomposición del mantillo y liberación foliar neta de nutrientes de Austrocedrus chilensis (D. Don) Pic. Serm. et Bizzarri en El Bolsón, Río Negro

open access: yesEcología Austral, 2004
Se determinó la descomposición de hojas, ramas y troncos en tres rodales maduros de Austrocedrus chilensis. La tasa de descomposición (k) foliar no mostró diferencias significativas entre rodales, siendo el promedio de 0.27 año-1.
