Sporangium Exposure and Spore Release in the Peruvian Maidenhair Fern (Adiantum peruvianum, Pteridaceae). [PDF]

, 2015
We investigated the different processes involved in spore liberation in the polypod fern Adiantum peruvianum (Pteridaceae). Sporangia are being produced on the undersides of so-called false indusia, which are situated at the abaxial surface of the ...

Sporangium motion sequences and spore dissemination.

, 2015
The sporangia have been gripped at their stalks with tweezers and adjusted vertically. Sporangium 2 in (D) is still situated on a false indusium. ac = apical cup; bc = basal cup; s1 = spores from apical cup; s2 = spores from basal cup.

Reducing copper inputs through integration of essential oil‐based formulations: laboratory and 2‐year vineyard evaluation against Plasmopara viticola

Pest Management Science, EarlyView.
Combining an essential oil (EO)‐based formulation with copper effectively controls Plasmopara viticola. Field trials showed a 92–99% protection with lower copper inputs, achieving a 45% copper reduction without compromising efficacy. This approach supports EO‐based products as sustainable alternatives for grapevine downy mildew management.

Lithochloron, a new genus of green algae residing in coral skeleton (Cladophorales, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Coral skeletons host diverse microbial communities, including endolithic green algae that contribute to holobiont functioning. The siphonous green alga Ostreobium (Bryopsidales) is arguably the best‐known coral endolith, but recent environmental sequencing has indicated that other lineages of green algae may also inhabit the coral skeleton ...
