Evaluation of climate change scenarios based on aquatic food web modelling [PDF]

open access: yes, 2008
In the years 2004 and 2005 we collected samples of phytoplankton, zooplankton and macroinvertebrates in an artificial small pond in Budapest. We set up a simulation model predicting the abundance of the cyclopoids, Eudiaptomus zachariasi and Ischnura ...

Recent advances of emergent extraction technologies to enhance bioactive compounds extraction of microalgae—An overview towards application in cosmetics

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Microalgae extracts show immense potential in cosmetics for their bioactivities; emerging extraction techniques enhance bioactive compound yield from microalgae. Abstract Microalgae have attracted significant interest in numerous sectors, particularly in the cosmetic industries, owing to their rich composition of bioactive compounds. This paper aims to

Seasonal succession of free-living bacterial communities in coastal waters of the Western Antarctic Peninsula

open access: yesFrontiers in Microbiology, 2016
The marine ecosystem along the Western Antarctic Peninsula (WAP) undergoes a dramatic seasonal transition every spring, from almost total darkness to almost continuous sunlight, resulting in a cascade of environmental changes, including phytoplankton ...

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Processes controlling the quantities of biogenic materials in lakes and reservoirs subject to cultural eutrophication [PDF]

open access: yes, 1980
The processes which control the growth, composition, succession and loss from suspension of phytoplankton algae are briefly reviewed, with special reference to function in eutrophic reservoir systems.

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

open access: yesJournal of Fish Biology, EarlyView.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Community assembly mechanism of phytoplankton in drinking water sources of tropical island, China

open access: yesFrontiers in Ecology and Evolution
IntroductionPhytoplankton, as primary producers in aquatic ecosystems, serves as indicators of the health of water environments. In tropical island regions facing the combined pressures of human activities and climate change, understanding the mechanism ...

Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

open access: yesJournal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from
