Comparing coastal storm impact to decadal change in barrier island ecosystems [PDF]

open access: yes, 2020
Highly dynamic coastal systems respond to disturbance events with a combination of topographic and vegetative changes. Sea level rise impacts on barrier islands have been quantified, but storm effects on vegetation are limited. Here we quantified barrier

Patch and matrix characteristics determine the outcome of ecosystem engineering by mole rats in dry grasslands [PDF]

open access: yesPeerJ, 2022
Background Burrowing mammals are important ecosystem engineers, especially in open ecosystems where they create patches that differ from the surrounding matrix in their structure or ecosystem functions.

Quantifying regional vegetation cover variability in North China during the Holocene: implications for climate feedback. [PDF]

open access: yesPLoS ONE, 2013
Validating model simulations of vegetation-climate feedback needs information not only on changes in past vegetation types as reconstructed by palynologists, but also on other proxies such as vegetation cover.

A Comprehensive Emission Inventory of Bbiogenic Volatile Organic Compounds in Europe: Improved Seasonality and Land-cover [PDF]

open access: yes, 2013
Biogenic volatile organic compounds (BVOC) emitted from vegetation are important for the formation of secondary pollutants such as ozone and secondary organic aerosols (SOA) in the atmosphere.

Assessment of soil erosion in olive orchards (Olea europaea L.) under cover crops management systems in the tropical region of Brazil [PDF]

open access: yes, 2020
In the tropics, water erosion is one of the most important factors leading to the degradation and deterioration of agricultural land. Olive orchards have a low canopy coverage, especially during the first years after planting, due to the low density of ...

The comprehensive evaluation of how water level fluctuation and temperature change affect vegetation cover variations at a lake of ecological importance (Poyang Lake), China

open access: yesEcological Indicators, 2023
Wetland vegetation is crucial to ecosystem services provided by lake wetlands worldwide. While environmental elements like hydrological factors and temperature have a wide impact on vegetation cover changes in lake wetlands, their effects on vegetation ...
