The present work focuses on the optimization of energy conversion process and use algal resources for biodiesel production with ultrasound microwave techniques in Oedogonium, Oscillatoria, Ulothrix, Chlorella, Cladophora, Spirogyra first time. fuel properties are investigated to optimize efficiency newly emerging feedstock. study indicates that optimized technique improves lipid extraction (38....

Sacoglossans are specialized marine herbivores that tend to have a close evolutionary relationship with their macroalgal hosts, but the widely distributed species Elysia viridis can associate with several algal species. However, most previous investigations on the field abundance and size distribution of E. viridis have focussed on Codium spp. in the British Isles, and algae from this genus are...

A survey was conducted from May to Oct of 2011 of the parasitoid community of the imported cabbageworm, Pieris rapae (Lepidoptera: Pieridae), in cole crops in part of the eastern United States and southeastern Canada. The findings of our survey indicate that Cotesia rubecula (Hymenoptera: Braconidae) now occurs as far west as North Dakota and has become the dominant parasitoid of P. rapae in th...

Photosynthesis is a fundamental process sustaining heterotrophic organisms at all trophic levels. Some mixotrophs can retain functional chloroplasts from food (kleptoplasty), and it is hypothesized that carbon acquired through kleptoplasty may enhance trophic energy transfer through increased host growth efficiency. Sacoglossan sea slugs are the only known metazoans capable of kleptoplasty, but...

The wellbeing of marine organisms is connected to their microbiome. Oysters are a vital food source and provide ecological services, yet little known about how climate change such as ocean acidification warming will affect We exposed the Sydney rock oyster, Saccostrea glomerata, orthogonal combinations temperature (24, 28 °C) pCO2 (400 1000 ?atm) for eight weeks used amplicon sequencing 16S rRN...

The objective of the study was to evaluate the effect of the biostimulant Kelpak on true protein and simple sugar contents of Dactylis glomerata and Festulolium braunii at different nitrogen rates. A field experiment was set up as a randomised sub-block design (split-split-plot) with three replicates. The following factors were ha, pure-sown grass species and cultivars (monoculture). Protein co...

The presence of potentially toxic elements (PTEs) in soils can upset the natural balance and increase risk PTE incorporation into food chain. use composite biochar with municipal sewage sludge compost (MSSC/C) be an effective way both managing waste, such as sludge, providing additive-supporting phytostabilization processes. effectiveness D. glomerata MSSC/C technique assisted industrially cont...

We quantified microscale flow forces and their ability to entrain the freshwater polychaete, Manayunkia speciosa, the intermediate host for 2 myxozoan parasites (Ceratomyxa shasta and Parvicapsula minibicornis) that cause substantial mortalities in salmonid fishes in the Pacific Northwest. In a laboratory flume, we measured the shear stress associated with 2 mean flow velocities and 3 substrate...

Isothiocyanates and substituted pyrazoles were combined to form a series of novel isothiocyanates with highly effective herbicidal activity. The target compounds were analyzed by elemental analysis, 1H-NMR, EI-MS and IR spectroscopy. The synthesized compounds, particularly compounds 3-1 and 3-7, exhibited good herbicidal activities against four weeds. The EC(50) values of compound 3-1 against E...
