Root foraging strategies and niche segregation of three mediterranean shrub species

open access: yesOikos, Volume 2024, Issue 11, November 2024.
Shrubs are usually adapted to stressful environments in which soil resources are limited, and thus, roots are fundamental for their biological success. However, root measures are challenging to collect, especially in field conditions and at the individual level.

Impact of various moisture regime on selected growth-production characteristics of Medicago sativa L. and Trifolium pratense L.

open access: yesActa Fytotechnica et Zootechnica, 2019
The aim of the experiment was to find out the impact of different moisture regime on selected indicators of the growth and production process of Medicago sativa L. cv. Zuzana and Trifolium pratense L. cv. Poľana. The pot experiment was carried out at the

International Biological Flora: Trapa natans†

open access: yesJournal of Ecology, Volume 112, Issue 10, Page 2386-2420, October 2024.
The water caltrop (Trapa natans L.) was once widely distributed in its native range, but is in some part (i.e. Europe) nowadays very rare, highly threatened and of conservation concern for still unknown reasons. It has been introduced beyond its native range (e.g.

Nutrient Stocks in Four Stages of a Lowland Rain Forest at Pasirmayang, Jambi, Central Sumatra, [PDF]

open access: yes, 1998
Studies of nutrient cycling of tropical forests should differentiate between dynamic stages of the forest. We studied the nutrient concentration (N, P, K, Ca and Mg) and phytomass of aboveground (living and non living parts) and belowground compartments (

Close to the edge: Spatial variation in plant diversity, biomass and floral resources in conventional and agri‐environment cereal fields

open access: yesJournal of Applied Ecology, Volume 61, Issue 9, Page 2075-2086, September 2024.
The strong edge effects we found in conventional cultivation support the premise that reducing field sizes could play a role in promoting in‐crop biodiversity. However, incorporating extensive field margins as an AEM would be more efficient at maximising the diversity of generalists whilst maintaining high yields.

THE USE OF CONIFEROUS PLANTS AS PHYTOREMEDIATORS OF TECHNOSOIL IN UKRAINIAN STEPPE [PDF]

open access: yes, 2018
In the process of coal mining, particularly under conditions of operation of mines, significant disturbance and pollution of land occurs, being especially relevant for agricultural lands.

Role of Surface Energy Fluxes in Urban Overheating Under Buoyancy‐Driven Atmospheric Conditions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 129, Issue 13, 16 July 2024.
Abstract Urbanization alters land surface properties in absorbing, reflecting and emitting radiation as well as infiltrating, evaporating and storing water. This consequently modifies surface energy and water fluxes and, thus, urban climates. Weak synoptic flow, clear sky conditions and higher surface temperatures in cities compared to their rural ...

Characterization of vegetation by microwave and optical remote sensing [PDF]

open access: yes
Two series of carefully controlled experiments were conducted. First, plots of important crops (corn, soybeans, and sorghum), prairie grasses (big bluestem, switchgrass, tal fescue, orchardgrass, bromegrass), and forage legumes (alfalfa, red clover, and ...

Effects of Ponderosa Pine Ecological Restoration on Forest Soils and Understory Vegetation in Northern Arizona [PDF]

open access: yes, 2017
The human exclusion of wildfire and overgrazing by livestock since settlement have caused dramatic changes in ponderosa pine (Pinus ponderosa Dougl ex Laws) forest ecosystems.

Stream Nitrogen Concentrations Across Arctic Vegetation Gradients

open access: yesGlobal Biogeochemical Cycles, Volume 38, Issue 2, February 2024.
Abstract The Arctic is experiencing dramatic climate‐induced changes, which could have substantial consequences for nutrient export from land to streams and, thus, in‐stream nutrient availability and composition. Arctic freshwater ecosystems are low‐productive systems often limited by nitrogen (N) availability.
