Effects of forest fragmentation on the weight of understory birds at the Biological Dynamics of Forest Fragments Project in Amazonia

open access: yesBiotropica, Volume 54, Issue 4, Page 852-859, July 2022., 2022
Deforestation and habitat fragmentation are known as the chief drivers of biodiversity loss. Habitat fragmentation in the Brazilian Amazon was found to affect the weight of birds that remained in isolated areas. Our results provide a novel analysis into how avian body mass responds to habitat fragmentation.

Global maps of soil temperature

open access: yesGlobal Change Biology, Volume 28, Issue 9, Page 3110-3144, May 2022., 2022
We provide global maps of soil temperature at a 1 km2 resolution, based on a global database of more than 8500 in situ soil temperature time series. We show that over the year, soils in cold and/or dry biomes are on average 3.6°C warmer, whereas soils in warm and humid environments are 0.7°C cooler than gridded air temperature.

Causes and consequences of liana infestation in southern Amazonia

open access: yesJournal of Ecology, Volume 108, Issue 6, Page 2184-2197, November 2020., 2020
Lianas are a pervasive and influential feature of the extensive forests at the southern edge of Amazonia. Our long‐term research here shows that liana infestation is closely linked to tree properties, including species‐level variables such as potential growth and wood density as well as the dimensions of individual trees. The growth of heavily infested

Seeing the woods through the saplings: Using wood density to assess the recovery of human‐modified Amazonian forests

open access: yesJournal of Ecology, Volume 106, Issue 6, Page 2190-2203, November 2018., 2018
Plant communities in human‐modified Amazonian forests appear to not be recovering a key functional property—wood density, which in turn may affect their ability to store carbon in the future. If the aim of conservation programs in tropical forests is to maintain existing rates of ecosystem functions, processes and services, then they must concentrate ...

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

Edge effects on fern community in an Atlantic Forest remnant of Rio Formoso, PE, Brazil Efeitos de borda na comunidade de samambaias em um remanescente de Floresta Atlântica de Rio Formoso, PE, Brasil

open access: yesBrazilian Journal of Biology, 2011
We have investigated how edge effects influence the fern community of Jaguarão Forest (08º 35' 49" S and 35º 15' 39" W), located in the district of Rio Formoso, Pernambuco, Brazil.

Patch and Landscape Predictors of Mammal Diversity and Their Trait‐Relationships in the Largest Atlantic Forest Island in Brazil

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
Urbanization and habitat fragmentation reshape mammal communities on Santa Catarina Island, one of the largest Atlantic Forest islands in Brazil. Using camera traps across protected forest patches, we show that species richness declines with urban and unvegetated matrices, while abundance increases in smaller and more isolated fragments dominated by ...
