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.

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 ...

Quantified vegetation change over 42 years at Cape Hallett, East Antarctica [PDF]

open access: yes, 2006
This paper reports on the remapping of a carefully documented vegetation plot at Cape Hallett (72°19′S 170°16′E) to provide an assessment of the rates of vegetation change over decadal time scales. E.D.

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.
