Synergistic efforts in specimen digitisation, curation and cataloguing of Brazil's megadiverse flora and funga

PLANTS, PEOPLE, PLANET, EarlyView.
The advancement of digital technologies has brought a rapid global information exchange, impacting all areas of our lives. This also applies to science. Knowledge, conservation and scientific innovation on global biodiversity are being strengthened and disseminated at unprecedented scales.

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

PLANTS, PEOPLE, PLANET, EarlyView.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

O sistema autopoiético e seus paradoxos

Sequência: Estudos Juridicos e Politicos, 2010
No presente trabalho, estuda-se a autopoiese, sua origem desde as ciências biológicas, com Maturana e Varela, até sua adaptação às ciências sociais com Niklas Luhmann, formulando uma autopoiese social.

Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

PLANTS, PEOPLE, PLANET, EarlyView.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Detecting extirpation: A localized approach to a global problem

PLANTS, PEOPLE, PLANET, EarlyView.
The global biodiversity crisis stems from a cascading series of extirpations driving species toward extinction. Addressing this crisis requires methods for early detection of extinction at local scales, where communities can mobilize conservation efforts.

A pipeline to compile expert‐verified datasets of digitised herbarium specimens for automated plant identification to accelerate taxonomy

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding and protecting plant life is essential for tackling the twin challenges of biodiversity loss and climate change. To support this, we have developed a new digital approach that helps identify plant species more quickly and accurately.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

Pest Management Science, EarlyView.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.
