Effects of Different Methods on the Comparison between Land Surface and Ground Phenology—A Methodological Case Study from South-Western Germany

Remote Sensing, 2016
Several methods exist for extracting plant phenological information from time series of satellite data. However, there have been only a few successful attempts to temporarily match satellite observations (Land Surface Phenology or LSP) with ground based ...

Weeds under the canopies of tree species submitted to different planting densities and intercropping Plantas daninhas sob copas de espécies arbóreas submetidas a consórcios e densidades de plantio diferentes

Planta Daninha, 2013
Assessing the growth and floristic composition of species that grow under the canopy of trees is important for weed control (WC). The objective of this study was to assess two experiments (E1 and E2), when the trees were two years and one year of age ...

Bacterial multi-resistance to antibiotics in water from plant cavities (phytotelms) in a deep tropical forest from Costa Rica

Cuadernos de investigación UNED, 2023
Introduction: The spread of antimicrobial resistance in natural environments continues to be reported throughout the world; nevertheless, there is no study about phytotelms (water in the natural cavities of plants) in the deep understory of tropical ...

Dryland management regimes alter forest habitats and understory arthropod communities [PDF]

, 2018
Dryland forests, those characterised as having low precipitation and soil nutrients, account for over a quarter of forests globally. Increasing their productivity often relies on irrigation and fertilisation, but the impacts on the wider habitat are ...

Net Ecosystem Exchange of CO₂ in Deciduous Pine Forest of Lower Western Himalaya, India

Resources, 2019
Carbon cycle studies over the climate-sensitive Himalayan regions are relatively understudied and to address this gap, systematic measurements on carbon balance components were performed over a deciduous pine forest with an understory layer.

The effects of stand characteristics on the understory vegetation in Quercus petraea and Q. cerris dominated forests [PDF]

, 2013
The shelterwood system used in Hungary has many effects on the composition and structure of the herb layer. The aim of our study was to identify the main variables that affect the occurence of herbs and seedlings in Turkey oak-sessile oak (Quercus cerris

The influence of leaf characteristics on epiphyllic cover : a test of hypotheses with artificial leaves [PDF]

, 1995
Studies of epiphyll ecology have been hindered by the biochemical and morphological variability of the leaf substrate. The use of artificial (plastic ribbon tape) leaves solved that problem in a study done at the Braulio Carrillo National Park, Costa ...

Estimating aboveground live understory vegetation carbon in the United States

Environmental Research Letters, 2017
Despite the key role that understory vegetation plays in ecosystems and the terrestrial carbon cycle, it is often overlooked and has few quantitative measurements, especially at national scales.

Rapid Increases in Forest Understory Diversity and Productivity following a Mountain Pine Beetle (Dendroctonus ponderosae) Outbreak in Pine Forests [PDF]

, 2015
The current unprecedented outbreak of mountain pine beetle (Dendroctonus ponderosae) in lodgepole pine (Pinus contorta) forests of western Canada has resulted in a landscape consisting of a mosaic of forest stands at different stages of mortality. Within
