High Fluctuating Asymmetry in Birds in a Large Neotropical City

Austral Ecology, Volume 51, Issue 2, February 2026.
Urbanisation is a powerful environmental force, negatively impacting the few organisms that persist in urban areas. Here, we investigated the relationship between urbanisation intensity and Fluctuating asymmetry (FA) in birds. Our results suggest that urbanisation (even at lower intensities) may impose stronger genetic and/or environmental stress on ...

The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Distinct bird communities in forests and fruit farms of Caatinga landscapes

Ibis, Volume 166, Issue 3, Page 1081-1091, July 2024.
Agricultural expansion and intensification drive changes in bird assemblages and contribute to the homogenization of communities. By working across the semi‐arid biome of the Caatinga in northeastern Brazil, this study is the first to compare the bird communities found in intensively managed fruit farms with those in remnant Caatinga forest patches. We

Co‐production of agroecological innovations to improve sustainability in South American fruit farms

People and Nature, Volume 6, Issue 2, Page 833-848, April 2024.
Abstract Agricultural intensification and expansion are the main drivers of biodiversity loss that continue to increase this century, especially in South America. International markets and global policy provide incentives and frameworks to address this, but these are unlikely to be effective unless farmers on the ground are enabled and motivated to ...

Semantic-cognitive aspects of intensification

Gragoatá, 2006
The present paper aims to focuse the semantic and cognitive aspects of the intensity processes. Thus takes the theoretic accounts of Cognitive Semantics, to which language encodes the cognitive schemas structured from our experience with reality ...

Dietary metabarcoding reveals the simplification of bird–pest interaction networks across a gradient of agricultural cover

Molecular Ecology, Volume 33, Issue 8, April 2024.
Abstract Agriculture is vital for supporting human populations, but its intensification often leads to landscape homogenization and a decline in non‐provisioning ecosystem services. Ecological intensification and multifunctional landscapes are suggested as nature‐based alternatives to intensive agriculture, using ecological processes like natural pest ...

Temporal mismatches in flight activity patterns between Pipistrellus kuhlii and Prays oleae in olive farms: Implications for biocontrol services potential

Journal of Applied Ecology, Volume 61, Issue 3, Page 526-537, March 2024.
Future research should consider mismatches between the temporal activity patterns of insectivorous bats and insect pests. Otherwise, the actual impact of agricultural intensification on bat‐mediated biocontrol services as well as the economic impact of their loss on the agriculture industry might be underestimated.
