Relative impacts of morphological alteration to shorelines and eutrophication on littoral macroinvertebrates in Mediterranean lakes [PDF]

open access: yes, 2015
Development of effective methods for assessing the ecological status of lakes based on littoral benthic fauna has been hampered by the lack of quantitative data on the relative impacts of key pressures on the benthic community.

Effect of soil waterlogging on below-ground biomass allometric relations in Norway spruce [PDF]

open access: yes, 2010
An increasing importance is assigned to the estimation and verification of carbon stocks in forests. Forestry practice has several long-established and reliable methods for the assessment of aboveground biomass; however we still miss accurate predictors ...

Production of Secondary Organic Aerosol During Aging of Biomass Burning Smoke From Fresh Fuels and Its Relationship to VOC Precursors [PDF]

open access: yes, 2019
After smoke from burning biomass is emitted into the atmosphere, chemical and physical processes change the composition and amount of organic aerosol present in the aged, diluted plume. During the fourth Fire Lab at Missoula Experiment, we performed smog-

Different biomass allocation strategies of geophytes and non-geophytes along an altitude gradient

open access: yesEcological Indicators, 2023
Biomass allocation strategies among geophytes and non-geophytes generally determine the ecological adaptation and impacts of herbaceous plants. Although geophytes and non-geophytes are key components of the biodiversity of subtropical forest ecosystems ...

Challenges in modelling dissolved organic matter dynamics in agricultural soil using DAISY [PDF]

open access: yes, 2008
Because dissolved organic matter (DOM) plays an important role is terrestrial C-,N-and P-balances and transport of these three components to aquatic environments, there is a need to include it in models.

Evaluation of Rice Straw Yield, Fibre Composition and Collection Under Mediterranean Conditions

open access: yesActa Technologica Agriculturae, 2019
Rice straw remains almost unutilised in the majority of cases and is usually burned. Data on rice residue production under European conditions are extremely limited.
