The present experiment was designed to investigate the subsequent influences of supplementing different levels of intact green seaweed Ulva lactuca (0%, 3%, and 5% DM) to growing sexually immature lambs during the growth period (74 d) on the seminal and testicular characteristics of sexually mature rams. Ulva lactuca was manually collected, adequately prepared, and then incorporated into lambs'...

Coastal ecosystems are subjected to global and local environmental stressors, including increased atmospheric carbon dioxide (CO2) (and subsequent ocean acidification) and nutrient loading. Here, we tested how two common macroalgal species in the Northwest Atlantic (Ulva spp. and Fucus vesiculosus Linneaus) respond to the combination of increased CO2 and nutrient loading. We utilized two levels...

Ulva Linnaeus genus (Ulvaceae, Ulvales) is an ubiquitous genus widely distributed in oceans and estuaries. Currently, 128 species (accepted taxonomically) have been listed all around the world [1]. Individuals of this genus are characterized by a broad range of environmental tolerance, high growth rate and photosynthetic activity leading to a relatively abundant natural biomass. Aditionnaly, in...

It has been demonstrated that treatment of algae at low pH values, similar to those found in the stomachs of herbivorous fishes, damages the algal cells, allowing digestive enzymes to enter the cells. However, the effects of the low pH treatment on the porosity of algal cell walls has not been examined. We tested the effects of low pH on the porosity of cells of four species of dietary algae, E...

Enrichment of nutrients and metals in seawater associated with anthropogenic activities can threaten aquatic ecosystems. Consequently, nutrient and metal concentrations are parameters used to define water quality. The European Union's Water Framework Directive (WFD) goes further than a contaminant-based approach and utilises indices to assess the Ecological Status (ES) of transitional water bod...

Objective: The primary objective is to morphologically identify a marine sponge from Sethubavachatram village in Tamil Nadu, India. Then the bacteria associated with sample synthesize silver nanoparticles and know antimicrobial property of samples. Methods: sponges identified by morphology found be Hippospongia intestinalis. Lysinibacillus macrolides. Silver were synthesikzed analyzed SEM TEM. ...
