Spore diversity among species of Blechnaceae in the Atlantic Forest

open access: yesActa Botânica Brasílica
The palynological diversity of Blechnaceae in the Atlantic Forest was investigated. While the monophyletic family belongs to the group of leptosporangiate ferns, a new classification proposed by recent phylogenetic study reorganizes the family and adds ...

Spore morphology of Onychium ipii Ching (Pteridoideae, Pteridaceae)

open access: yesTurczaninowia, 2017
The ultrastructure of the spore surface of Onychium ipii Ching (Pteridoideae, Pteridaceae) was investigated by using of scanning electron microscopy. Spores of Onychium ipii are trilete, tetrahedral, with hemispherical distal side and convex proximal one.

Pteris madhusoodananii (Pteridaceae), a new fern species from India

open access: yesNordic Journal of Botany, EarlyView.
Pteris madhusoodananii sp. nov. (Pteridaceae), from the Kolli hills of Eastern Ghats, India, is described. The new taxon is morphologically distinct, characterized by a unique lamina texture and coloration, specific pinna‐pinnule architecture and distinct spore micromorphology.

Taxonomy of a novel and a new geographical record of Nigropunctata species (Pallidoperidiaceae) on Bambusa vulgaris from northern Thailand

open access: yesNordic Journal of Botany, EarlyView.
Nigropunctata is an understudied genus of bambusicolous fungi, and its diversity in Thailand remains poorly known. This study aimed to investigate species of Nigropunctata associated with bamboo in Thailand using morphological observations along with multi‐locus phylogenetic analyses of the internal transcribed spacer (ITS), large subunit (LSU), RNA ...

Taxonomy and phylogeny of the intercontinental disjunctive ferns: series Reniformia Adiantum

open access: yesNordic Journal of Botany, EarlyView.
There are disputed opinions about the three taxa of series Reniformia, namely A. nelumboides X.C.Zhang (A. reniforme var. sinense Y.X.Lin), A. reniforme var. reniforme, and A. reniforme var. asarifolium (Willd.) R. Sim, owing to their similar morphology but intercontinental disjunctive distribution and close lineage with the series Venusta (only ...

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

open access: yesNordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

Palynological analysis of Dennstaedtiaceae taxa from the Paranaense Phytogeographic Province that produce Trilete spores II: Microlepia speluncae and Pteridium arachnoideum

open access: yesAnais da Academia Brasileira de Ciências, 2016
The spore morphology and wall ultrastructure of Microlepia speluncae and Pteridium arachnoideum from the Paranaense Province were analyzed with LM, SEM and TEM and a comparative analysis was carried out.

Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

open access: yesOikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...

Endophytic fungi from two isolated Bethencourtia palmensis populations: metabolomic and bioactivity fingerprinting

open access: yesPest Management Science, EarlyView.
We compared two island populations of Bethencourtia palmensis and their culturable endophytic fungi, revealing distinct plant chemistries and a higher biopesticidal potential in the endophytic fungi from La Palma population along with high potential for the discovery of novel compounds.
