Chemical constituents of liverwort (Porella cordaeana) extracts have been identified using solid-phase microextraction-gas chromatography mass spectrometry (SPME-GC/MS). The methanol, ethanol and ethyl acetate extracts were rich in terpenoids such as sesquiterpene hydrocarbons (53.12%, 51.68%, 23.16%), and monoterpene hydrocarbons (22.83%, 18.90%, 23.36%), respectively. The dominant compounds i...

Pseudoleptocheliajuliae n. sp. is described from Puerto Rican waters in depths from 1 to 28 m. The new species and P. fairgo from western Australia are the only members of the genus as defined in this revision that have a distinct process on the posterior margin of the cheliped carpus. The male of P. juliae is distinguished from that of P. fairgo by this process being sub-acute and having a dis...

1. The ecological effects of invasive species depend on myriad environmental contexts, rendering understanding problematic. Functional responses provide a means to quantify resource use by consumers over short timescales and could therefore provide insight into how the effects of invasive species vary over space and time. Here, we use novel in situ microcosm experiments to track changes in the ...

Compared to their fossil counterparts, living brachiopods are investigated far less often, due occurrence in remote environments such as dark caves or deep environments. Due the scarcity of studies targeting situ brachiopods’ populations, large-scale information on distribution and ecological preferences is still lacking, especially hardgrounds. The extensive employment remotely operated vehicl...

The myxobacterial fungicide, ambruticin, kills the yeast, Hansenula anomala, with high efficacy (MIC 0.05 microg/ml), but only when the cells are growing. The earliest effect, observed almost immediately after the addition of the antibiotic, is a transient but substantial increase of intracellular glycerol, followed by an accumulation of triacylglycerols and free fatty acids. At about the time ...
