The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Origem dos contrastes texturais de horizontes subsuperficiais em solos do Pantanal Norte [PDF]

open access: yes, 2013
The Pantanal region can be characterized as a quaternary floodplain with predominant sedimentation in the form of alluvial fans. In the geomorphologic and sedimentary evolution, the avulsion process is inherent to this depositional system and its ...

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

open access: yesAustral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.
