Effect of Paper Sludge and Dendromass on Properties of Phytomass Pellets

Applied Sciences, 2020
Woody and agricultural wastes are important fuels in many countries, and have the potential of being even more important in the future. The main problems of plant biomass combustion are low ash melting temperatures and increased emissions.

Ecology of bryophytes along altitudinal and latitudinal gradients in Chile [PDF]

, 2002
The bryophyte vegetation in twenty-eight hectare plots in forests of S-Chile between 38° and 42°S and sea level and the forest line has been studied. Since bryophytes are fully dependend on atmospheric water and nutrient supply, they are good indicators ...

Melon Seedlings Phytomass under Poultry Litter Biochar Doses

Agricultural Sciences, 2021
The use of organic waste for the preparation of seedling substrates is an important environmental and economic option. In this perspective, substrates using biochar emerges as an alternative for seedling production due to their favorable physical and chemical characteristics. The present study aimed to evaluate the efficiency of doses of poultry litter

Recurrent drought amplifies drought impacts and increases seasonal synchrony in mountain grassland communities

Oikos, EarlyView.
Climate change increases the recurrence of drought events with strong repercussions on grassland ecosystems. While the effects of single drought events on ecosystem structure and functioning are well understood, it is largely unknown whether and how recurrent drought events modify ecosystem responses to subsequent drought.

Generic Models of Willow (genus Salix L.) Tree Phytomass: a Meta-Analysis

Лесной журнал
Climate change has a negative impact on the environment, including forest ecosystems. However, forests are not only passive objects affected by climate change, but also, due to their ability to absorb and accumulate carbon, they themselves can ...

Taxonomic, Phylogenetic and Functional Diversity Behave Differently Under Disturbance Pressure and Complex Land‐Use History: Assembly Rules in Grassland Communities

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Grasslands in the Alps are undergoing land‐use change triggering ecological succession and affecting community composition. Taxonomic, phylogenetic, and functional diversity are used as complementary information to infer on community assembly processes, supporting conservation practices.

Soil background effects on UAS and proximal remote sensing‐derived vegetation indices

Agronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Exposed soil, due to low vegetation cover or in open canopy crops, influences scene reflectance derived from remotely sensed data. An experiment was conducted in College Station, TX, to investigate the potential of six unmanned aerial systems (UASs)‐derived and proximally sensed vegetation indices (VIs) in suppressing soil background ...

Tree Stands and Their Productivity Dynamics at the Upper Growing Limit in Khibiny on the Background of Modern Climate Changes [PDF]

, 2019
Within the ecotone of the upper limit of woody vegetation on the southeastern macroslope of the Khibiny Mountain ridge (Kola Peninsula), the spatial and age structure, as well as features of the phytomass accumulation of spruce–birch stands, were studied.
