Assessing the mechanisms and impacts of shrub invasion in forests: A meta‐analysis

Journal of Applied Ecology, Volume 60, Issue 11, Page 2314-2326, November 2023., 2023
Taken together, these results suggest that restoration efforts should focus on (i) increasing the presence of strong native competitors or functionally diverse native communities, (ii) decreasing sources of invasive shrub propagules while keeping the canopies closed when invasion occurs via high propagule pressure, (iii) avoiding management techniques ...

Fish on Fire: Shifts in Amazonian fish communities after floodplain forest fires

Journal of Applied Ecology, Volume 60, Issue 8, Page 1637-1646, August 2023., 2023
Amazonian fish communities change after floodplain forest fires. Unburnt forests have diverse fish communities, with a large proportion of unique and small omnivorous species. In contrast, carnivores and detritivores become more common in fire scars and white‐sand savannas formed after forest fires. Less omnivore fish after forest fires can reduce tree

Large‐scale impacts of selective logging on canopy tree beta‐diversity in the Brazilian Amazon

Journal of Applied Ecology, Volume 60, Issue 6, Page 1181-1193, June 2023., 2023
Minimal impacts on tree beta‐diversity across large spatial scales points towards the retention of substantial conservation value in logged tropical forests. Strong subtractive heterogenization in very large trees indicates the breakdown of broad scale patterns of composition with potential negative consequences for recruitment processes, fauna reliant

Providing long‐term care: Options for a better workforce

International Social Security Review, Volume 75, Issue 3-4, Page 121-144, July-December 2022., 2022
Abstract Older people and their care workers have been disproportionately affected by the COVID‐19 pandemic. Many OECD Member countries have taken measures to contain the spread of the infection and improve the care workforce. Yet the health crisis is highlighting and exacerbating pre‐existing structural problems in the long‐term care (LTC) sector.

Why forest fails to recover after repeated wildfires in Amazonian floodplains? Experimental evidence on tree recruitment limitation

Journal of Ecology, Volume 109, Issue 10, Page 3473-3486, October 2021., 2021
Our experimental evidence suggests that soil nutrient limitations may slow down forest recovery after repeated wildfires in Amazonian floodplains. Yet, because floodplain trees are able to germinate from seeds and establish successfully in twice burnt forests, seed limitation seems to be the reason why forest recovery fails persistently. Seeding native

Stakeholders engagement as an important step for the long‐term monitoring of wild ungulate populations

Ecological Solutions and Evidence, Volume 2, Issue 3, July–September 2021., 2021
Ongoing monitoring is essential for the management of wildlife populations. The collaboration between local stakeholders and researchers is envisaged as an important partnership to monitor game species for long periods and vast territories. Here, we implemented a framework aimed at broadening the field applicability of Distance sampling techniques to ...
