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

open access: yesOikos, 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.

Effect of fertilization on the distribution of root phytomass and the yield of meadow stands

open access: yesPlant, Soil and Environment, 2004
In 1998-2000 the effect of fertilization on the quantity, stratification of root phytomass and yields of dry mass on mesophyte meadow stands was studied.

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

open access: yesAgronomy 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 ...

The dynamics of growing herbaceous plants in the soil contaminated with sodium formiate

open access: yesMokslas: Lietuvos Ateitis, 2010
Salts are most frequently used for road maintenance in cold seasons in Lithuania. In case the use of salts is mandatory, the proposal is to apply as small amounts as possible following the norms of use.

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

open access: yes, 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.

Estimation of above-ground phytomass and carbon in tree resources outside the forest (TROF): A geo-spatial approach

open access: yesBanko Janakari, 2015
This study aims to estimate above-ground phytomass and carbon of TROF ecosystem in part of Bijnor district in Uttar Pradesh state of India using IRS P6 LISS-IV satellite image by geo-spatial approach coupled with field sampling. Chacko’s formula was referred to compute number of samples in each TROF types and the sample plot size in each stratum was ...
