Unexpected spatial aggregation between two species of hummingbirds and their inconsistent spatial interactions with native and exotic plants in an urban ecological reserve

open access: yesIbis, Volume 167, Issue 4, Page 927-944, October 2025.
Hummingbirds play an important role as pollinators and are one of the primary examples of animal–plant coevolution. However, factors such as land‐use change, urbanization, exotic species introductions and the disappearance of native plants can negatively affect the persistence of hummingbird populations.

Bioinspired Design of Isotropic Lattices with Tunable and Controllable Anisotropy

open access: yesAdvanced Engineering Materials, Volume 27, Issue 11, June 2025.
This study introduces nested isotropic lattices, integrating architectural elements like nesting orders and orientations inspired by bioarchitectures. The design enables tunable anisotropy across nine mono‐nest and twenty multi‐nest lattices with 252 parametric variations, demonstrating transitions from shear‐ to tensile‐compression‐dominant behaviors ...

Droplet dynamics on slippery surfaces: small droplet, big impact

open access: yesBiosurface and Biotribology, Volume 5, Issue 2, Page 35-45, June 2019., 2019
The dynamic interaction of droplets with slippery surfaces is essential to various industrial applications, such as anti‐icing, water‐repellency or water‐harvesting, anti‐bacterial, and phase change heat transfer. With recent progress in materials, manufacturing as well as learning from nature, the physics of droplet dynamics has been greatly enriched ...

Reactivation of Chagas Disease in the Central Nervous System Among Heart Transplant Recipients: A Clinical Series From Brazil, 2006–2023

open access: yesTransplant Infectious Disease, Volume 27, Issue 2, March/April 2025.
ABSTRACT Background Chagas disease is a relevant cause of heart transplantation. The risk of reactivation is a potential concern. This study aimed to describe the reactivation of Trypanosoma cruzi in the central nervous system (CNS). Methods We performed a retrospective study of all heart transplants for Chagas disease undertaken between 2006 and 2023 ...

Evolving paradigms of aspen ecology and management: impacts of stand condition and fire severity on vegetation dynamics

open access: yesEcosphere, Volume 6, Issue 1, Page 1-16, January 2015., 2015
Quaking aspen (Populus tremuloides Michx.) comprises only a small fraction of western USA forests, yet contributes significant biological diversity and is considered by many to be the most important deciduous forest type in western North America. There is currently a high level of concern in the western United States as many seral aspen populations are

Links between the ornamental sector and alien plants in Southern Africa

open access: yesGeo: Geography and Environment, Volume 12, Issue 1, January‐June 2025.
Short Abstract Given the historical role of the ornamental industry in plant invasions in Southern Africa, we assess how the ornamental sector and practices there relate to alien plants. The sector's operation and gardening practices show different expressions of the typical cultural hybridity of postcolonial states, where alien plants and foreign ...

Revisiting an ecophysiological oddity: Hydathode‐mediated foliar water uptake in Crassula species from southern Africa

open access: yesPlant, Cell &Environment, Volume 47, Issue 2, Page 460-481, February 2024.
Abstract Hydathodes are usually associated with water exudation in plants. However, foliar water uptake (FWU) through the hydathodes has long been suspected in the leaf‐succulent genus Crassula (Crassulaceae), a highly diverse group in southern Africa, and, to our knowledge, no empirical observations exist in the literature that unequivocally link FWU ...
