Juncus emmanuelis [PDF]

open access: yes, 2018
This species is endemic to a small area in the southwestern Iberian Peninsula, with subpopulations scattered in approximately 16 localities. It is assessed as Endangered (EN B2ab(ii,iii,iv)) because it has an Area of Occupancy (AOO) of less than 500 km2 ...

A linear sequence of extant families and genera of lycophytes and ferns [PDF]

open access: yes, 2011
Throughout the history of the classification of extant ferns (monilophytes) and lycophytes, familial and generic concepts have been in great flux. For the organisation of lycophytes and ferns in herbaria, books, checklists, indices and spore banks and on

Limitative mycotic factors for some plants from the Romanian coast of the Black Sea [PDF]

open access: yesScientific Annals of the Danube Delta Institute, 2012
Among factors which may diminish plant populations, there also the parasitic fungi. Most endangered tracheophytes seem to be those of coastal areas. In recent years almost all European beaches suffered profound modifications due to tourism.

Potential conservation of circadian clock proteins in the phylum Nematoda as revealed by bioinformatic searches [PDF]

open access: yes, 2014
Although several circadian rhythms have been described in C. elegans, its molecular clock remains elusive. In this work we employed a novel bioinformatic approach, applying probabilistic methodologies, to search for circadian clock proteins of several of

Genome-wide identification of Reverse Transcriptase domains of recently inserted endogenous plant pararetrovirus (Caulimoviridae)

open access: yesFrontiers in Plant Science, 2022
Endogenous viral elements (EVEs) are viral sequences that have been integrated into the nuclear chromosomes. Endogenous pararetrovirus (EPRV) are a class of EVEs derived from DNA viruses of the family Caulimoviridae.

Life after herbarium digitisation: Physical and digital collections, curation and use

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Societal Impact Statement Collections of dried plant specimens (herbaria) provide an invaluable resource for the study of many areas of scientific interest and conservation globally. Digitisation increases access to specimens and metadata, enabling efficient use across a broad spectrum of research.

The biodiversity audit approach challenges regional priorities and identifies a mismatch in conservation [PDF]

open access: yes, 2012
1. Despite a strong uptake of evidence-based approaches, conservation often proceeds from a grossly incomplete understanding of species priorities. To optimize conservation impact within a biogeographical region, quantitative knowledge is needed of the ...

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

open access: yesPLANTS, 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.
