Spatial and temporal variability of macrobenthic communities in Chalus Shore of the Caspian Sea

open access: yes‬‭Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 2011
The changes in density and biomass of macrobenthos were seasonally investigated from winter 2005 till fall 2006 in southern Caspian Sea. Samples were taken with a 225cm2 Van Veen grab from depths of 7 and 20 meters along two transects: Line 8 area ...

Ecological pellets from brown coal and biomass

open access: yesActa Montanistica Slovaca, 2007
One way of renewable energy sources applications in the Czech republic is a cultivation of biomass plants. After the biomass reformation, it is possible to add it to palletizing mixes with coal and delulfurisative additives. Possibilities of brown coal of palletizing with biomass adds were tested recently.

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

open access: yesAdvanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.

Evaluation of the reserve effect in a marine protected area in Sagres (PNSACV) [PDF]

open access: yes, 2019
Marine Protected Areas (MPAs), especially when set up as marine reserves, have been found beneficial for fish communities and species worldwide. Evaluation of MPA effects needs to be done to understand whether existing protection measures are efficient ...

Assessing the ecological status of Italian lagoons using a biomass-based index

open access: yesMarine Pollution Bulletin, 2018
We compared the performance of abundance- and biomass-based M-AMBI in the 13 major Italian lagoons, using a benthic dataset constituted by 208 sampling sites. The relative importance of ecological groups changed when using abundance or biomass, sometimes leading to an improved ecological status classification.
