Circumscription of three new taxa of Merismopedia‐like Cyanobacteria shows how far convergent evolution can go

open access: yesJournal of Phycology, EarlyView.
Abstract The genus Merismopedia (Merismopediaceae, Chroococcales), characterized by rectangular colonies with cells arranged in regular perpendicular rows and columns, represents a challenging study system due to its limited cultivability. The genus recently underwent taxonomic revision using cultivation‐independent techniques and a polyphasic approach.

A compositional data (CoDa) method for soil organic carbon VISNIR measurement, preventing moisture interference

open access: yes
Comunicación oral presentada en Budapest Soil Health Forum on 4th December 2024, in Budapest, HungarySoil organic matter content (SOM) has an important role in modulating atmospheric CO2, while soil organic carbon (SOC) is the best marker of SOM.

Short‐term changes in photographed dental calculus coverage and pooled supragingival microbiota after baked dental treats containing a pomegranate–propolis blend or sodium hexametaphosphate in dogs

open access: yesJournal of Small Animal Practice, EarlyView.
Objectives To compare short‐term changes in the photographed percentage of visible tooth surface covered by pre‐existing dental calculus among dogs receiving additive‐free baked treats, sodium hexametaphosphate‐containing treats or pomegranate–propolis‐containing treats, and to describe pooled supragingival bacterial profiles before and after the ...

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Ecological determinants of stability in dryland plant communities

open access: yesNew Phytologist, EarlyView.
Conceptual framework for partitioning the drivers of community stability. Summary Community stability is often presented as crucial for sustaining ecosystem services under environmental change. Yet, its determinants (dominance, asynchrony in species fluctuations, averaging effect of species diversity) have rarely been disentangled in natural systems ...

Jasmonate biosynthesis regulates key events in barley vegetative and reproductive development

open access: yesNew Phytologist, EarlyView.
Generation and general phenotypes of hvaoc mutants. Summary Cereal grain is a global food staple. Filial tissues in grain, such as the embryo and endosperm, grow embedded in the maternal ovule and surrounding ovary wall. Maternal tissues provide nutrition and protection but are progressively reduced and degraded as filial tissues expand, driving grain ...

Provenance and environment jointly shape early regeneration in fir and beech: evidence from distributed participatory trials across Europe

open access: yesNew Phytologist, EarlyView.
Location of fir (Abies) and beech (Fagus) seed provenances and the experimental field sites called micro‐gardens. Summary Forest regeneration is shaped by strong demographic filters during germination and early establishment, yet the relative contributions of seed provenance and environment remain poorly understood under natural conditions. We combined

Canopy‐scale VPD reduction in a mature forest alters stomatal response to soil drought in Pinus sylvestris L.

open access: yesNew Phytologist, EarlyView.
In a mature Scots pine forest (Pfynwald, Switzerland), canopy vapor pressure deficit (VPD)a was reduced with a misting system (a) and combined with a throughfall‐exclusion roof that imposed soil drought (b). Under the roofs (c), trees at ambient VPD closed their stomata steeply as predawn water potential (ΨPD) fell, reaching closure around −1.2 MPa ...
