Higher bee species richness in conservation areas compared with non‐conservation areas in south‐west Germany

open access: yesInsect Conservation and Diversity, Volume 18, Issue 2, Page 191-205, March 2025.
Malaise trap records from Baden‐Württemberg, Germany, show that sites within conservation areas have higher bee species richness than sites in non‐conservation areas. Endangered bee species were closely associated with sites in conservation areas. However, flying insect biomass from 2018 to 2023 was not affected by conservation status.

Biological carbon sequestration: perspectives for application of introduced tree species (case study of Quercus rubra L.)

open access: yesІнтродукція Рослин, 2019
One of the most important tasks of modern biogeochemistry is to decrease the concentration of carbon dioxide in troposphere. Biological carbon sequestration is widely used for this purpose as a simple and effective method; and sequestration efficiency is

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

open access: yes, 2001
Six altitudinal transects through temperate rain forests were studied at different latitudes in the South and North Island of New Zealand with respect to species numbers of bryophytes, cover and phytomass of epiphytic bryophytes, composition of life ...

PRODUCTIVITY AND CONTENT OF MACRO- AND MICROELEMENTS IN THE PHYTOMASS OF GROUND VEGETATION OF TYPICAL AND UNIQUE TAIGA FORESTS OF THE NORTHERN URALS (EXAMPLE OF SPRUCE-FIR FORESTS OF THE PECHORA-ILYCH NATURE RESERVE)

open access: yes, 2020
Most woodlands of the Northern Eurasia are represented by bilberry-green moss spruce-fir forests. At the same time, a tall herb type of spruce-fir forests that occupies a much smaller area was identified and described.

Trees First Inhibit Then Promote Litter Decomposition in the Subarctic

open access: yesEcology Letters, Volume 28, Issue 1, January 2025.
Trees may influence organic matter decomposition at the soil surface and in the soil, via effects on the fungal community. However, it is still debated whether such tree effects inhibit (Gadgil effect) or promote (priming) rates of litter decomposition.

Selection and Genetic Characterization of Stevia Genotypes Based on the Rebaudioside A and Total Steviol Glycosides for Brazilian Savanna

open access: yesInternational Journal of Agronomy, Volume 2025, Issue 1, 2025.
The stevia plant has natural sweetening properties that are attracting worldwide interest. Given the significant importance of this plant, the aim of the study was to estimate genetic parameters to characterize and select superior stevia genotypes based on rebaudioside A and total steviol glycoside contents.
