Geomorphometric characterisation of natural and anthropogenic land covers

open access: yesProgress in Earth and Planetary Science, 2020
The scientific community has widely discussed the role of abiotic and biotic forces in reshaping the Earth’s surface. Currently, the literature is debating whether humans are leaving a topographic signature on the landscape.

The influence of land use on the spectrum of landform transformations (a case study of the Russian Arctic)

open access: yesRussian Journal of Earth Sciences, 2022
Human activity has a profound effect on relief. Therefore, it is crucial to study the anthropogenic relief transformation. The field of study is relatively young, although rapidly developing.

Anthropogenic impacts on multi-scale ecosystems

open access: yesEcological Informatics, 2012
Natural influences and human activities continually bring about changes in ecosystems. It is becoming increasingly clear that species are less able to adapt to natural changes at local and regional scales when those changes are compounded by human-caused alterations (UNEP, 1995; Yang and Zhao, 2008; Yang, 2011).

A Citizen Science Trial to Assess Perception of Wild Penguin Welfare

open access: yesFrontiers in Veterinary Science, 2021
Wild penguins are facing increased threats to their populations and their welfare as a consequence of human activities. Understanding the perception of animal welfare is essential to identify ethical concerns related to the negative impact of ...

Diversity of Agaricomycetes at the forest-city interface of the Adolpho Ducke Forest Reserve, Manaus, Central Amazonia [PDF]

open access: yesBrazilian Journal of Biology
Macrofungal diversity is essential to forest ecosystems, supporting carbon cycling and plant community structure. However, anthropogenic disturbance threatens this diversity, particularly near urban areas.

Assessment of Artificial Light at Night Across Geographical Features in the Sicilian Coastal Zone

open access: yesLand
This study investigates the impact of artificial light at night (ALAN) along the Sicilian coasts, using satellite data from 2016 to 2023, focusing on three distinct spatial domains: terrestrial areas within 1 km from the coastline, marine areas extending

The Pyrogenic Archives of Anthropogenically Transformed Soils in Central Russia

open access: yesGeosciences, 2021
Charred materials (anthracomass) stored within a soil constitute a major part of its pyrogenic archive and could provide evidence of past fire events, both natural and anthropogenic.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

La compensation écologique permet-elle vraiment de tendre vers l’absence de perte nette de biodiversité ?

open access: yesCybergeo
Since 2016, French law has pursued the objective of no net loss of biodiversity by requiring projects with impacts on biodiversity to avoid, reduce, and then compensate for these impacts.
