Ibis, Volume 165, Issue 3, Page 986-997, July 2023., 2023 Seasonal variation in tropical and subtropical systems can have different effects on bird species depending on the resources they use and how they use them. However, despite recent research advances, knowledge of the drivers of the presence and abundance of species in different seasons is still limited for most tropical bird species.

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

Functional Ecology, Volume 36, Issue 2, Page 341-355, February 2022., 2022 A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Tropical tree species span a range of life‐history strategies within a fast–slow continuum. The position of a species within this continuum is thought to reflect a negative relationship between growth and storage, with fast‐growing species allocating ...

Ecological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022 Tropical forests have been rapidly deforested and degradation worldwide has outpaced biodiversity field sampling. We here show that a simple sampling protocol carried out by a non‐specialist can lead to inexpensive and highly reliable ecological data.

Frugivory underpins the nitrogen cycle
Functional Ecology, Volume 35, Issue 2, Page 357-368, February 2021., 2021 A free Plain Language Summary can be found within the Supporting Information of this article. Abstract Tropical rainforests are populated by large frugivores that feed upon fruit‐producing woody species, yet their role in regulating the cycle of globally important biogeochemical elements such as nitrogen is still unknown.
