Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

When growth form fossilizes: the description of a new liverwort species of the family Metzgeriaceae from the Cretaceous Las Hoyas site, with insights into its architecture and life mode

open access: yesPalaeontology, Volume 69, Issue 4, July/August 2026.
Abstract Examining the liverwort fossil collection from the Las Hoyas site, which was previously classified as Thallites sp., led to the discovery of a new species of Metzgeriales: Metzgeriites gynothallicus. This species is characterized by the presence of both asexual (propagule branches) and sexual (female branches bearing sporophytes) reproductive ...

Dryopteridaceae (Polypodiopsida) no estado de Minas Gerais, Brasil

open access: yesLundiana: International Journal of Biodiversity, 2009
A taxonomic survey of Dryopteridaceae Herter (Polypodiopsida) was carried out in the state of Minas Gerais as a contribution to the knowledge of the state fern flora. This study was based on personal collections, field observations and material deposited in the Brazilian herbaria.

Detecting Forest Water‐Availability and Biomass Patterns Through a Retrospective Study in a Mediterranean Region

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Latent heat (λ $\lambda $ET) fluxes are a major component of the hydrological cycle globally. According to recent models and experimental observations, during droughts, wetter regions respond by increasing λ $\lambda $ET, while drier regions exhibit decreasing trends due to vegetation water stress.

Plant fossils in the Carboniferous beds of the motorway route at Bizovik

open access: yesGeologija, 2002
Study of fossil plants that were found during construction work of the Eastern Ljubljana motorway at Bizovik demonstrated that similar plants flourished in the uniform Euroamerican floristic area that extended in the Late Carboniferous from the present ...

A Global, Taxon‐Stratified, High‐Resolution Sampling‐Effort Dataset From GBIF for Bias‐Aware Ecological Modelling

open access: yesDiversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Introduction and Aim Spatiotemporal and taxonomic sampling bias in biodiversity occurrence data poses critical challenges for robust ecological inference, species distribution models (SDMs), and conservation planning. Despite the exponential growth in global biodiversity records over recent decades, these biases persist.

Genetic Diversity Impacts Climate‐Induced Species Range Shifts

open access: yesEcology Letters, Volume 29, Issue 4, April 2026.
Genetic diversity may buffer species against climate‐driven range contractions and facilitate expansions, but its role at a global scale remains unclear. Using 4673 range shift estimates for 1888 species, we show that higher genetic diversity reduces trailing edge contractions under rapid warming and accelerates leading edge expansions under moderate ...

Plants and Insect Eggs: First Report of a Katydid Using a Fern as Host for Oviposition

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Ferns are the second most diverse lineage of vascular plants worldwide and are particularly abundant in tropical forests. However, the ecological significance of such remarkable diversity has been often underestimated. In this article, we report for the first time the observation of ferns, specifically Polytaenium cajenense (Desv.) Benedict ...

A global review of chromosome number and genome size for the filmy ferns family (Hymenophyllaceae, Polypodiopsida) [PDF]

open access: yesRodriguésia
Hymenophyllaceae is a fern family comprising around 450 species distributed among nine genera. Genome size and chromosome number have been recurring research target for Hymenophyllaceae in taxonomic and evolutionary studies. However, there is currently a
