FLESHY ALCYONARIANS FROM SOUTHERN FORMOSA

Reproductive cycle of Bolinus brandaris (Gastropoda: Muricidae) in the Ria Formosa lagoon (southern Portugal)

The purple dye murex Bolinus brandaris is a commercially valuable gastropod in Portugal. However, there is a lack of knowledge on the reproductive cycle in Atlantic populations of this species. In this context, the reproductive cycle of B. brandaris from the Ria Formosa lagoon, southern Portugal, was studied using standard histology and light microscopy and the calculation of bio-physiological ...

Grayanane Diterpenoids from the Fruits of Pieris formosa

Many species of the family Ericaceae, such as the plants belonging to the genera Pieris, Rhododendron, Lyonia, Kalmia, and Leucothoe, are usually rich in grayanane-type diterpenoids with a 5/7/6/5 ring system, which is responsible for the toxicity of these species [1, 2]. Recently, a series of novel highly acylated diterpenoids with specific 3,4-secograyanane skeleton have been reported from Rh...

New Antifeedant Grayanane Diterpenoids from the Flowers of Pieris formosa.

Three new grayanane diterpenoids, pierisoids C‒E (1-3), as well as 10 known ones (4-13), were evaluated from the flowers of Pieris formosa, which is used as an insecticide in rural areas of China. Their structures were elucidated on the basis of extensive 1D and 2D NMR spectroscopic data analyses. Significant antifeedant activity of 1, 3 and 10 against the beet armyworm (Spodoptera exigua) was ...

The Nature of the Tuberose Fleshy Mole

Tidal controls on trace gas dynamics in a seagrass meadow of the Ria Formosa lagoon (southern Portugal)

Coastal zones are important source regions for a variety of trace gases, including halocarbons and sulfurbearing species. While salt marshes, macroalgae and phytoplankton communities have been intensively studied, little is known about trace gas fluxes in seagrass meadows. Here we report results of a newly developed dynamic flux chamber system that can be deployed in intertidal areas over full ...
