Rotation of the c‐Ring Promotes the Curvature Sorting of Monomeric ATP Synthases [PDF]

open access: yesAdvanced Science, Volume 10, Issue 31, November 3, 2023., 2023
An active curvature sorting of monomeric ATP synthases into lipid nanotubes is measured under rotating conditions. As suggested by coarse‐grained simulations, the rotational movement of proteins produces a hydrophobic mismatch at the protein–lipid interface leading to a membrane‐mediated attractive interaction among proteins.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient [PDF]

open access: yesNew Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Thermoregulatory ability and mechanism do not differ consistently between neotropical and temperate butterflies

open access: yesGlobal Change Biology, Volume 29, Issue 15, Page 4180-4192, August 2023., 2023
We studied how temperate and neotropical butterflies respond to temperature change. Neotropical butterflies were better at regulating their body temperature than temperate butterflies, mainly because at high air temperatures neotropical butterflies cooled themselves more.

Upper thermal tolerances and vulnerability to global warming in a Brazilian Caatinga fish Astyanax bimaculatus (Linnaeus, 1758) population

open access: yesAustral Ecology, Volume 47, Issue 6, Page 1157-1161, September 2022., 2022
Abstract Global warming is predicted to increase both average temperatures and the frequency and duration of heat waves. Tropical ectotherms, particularly those living in warm environments are more prone to receive heat impacts. Then, it is crucial to identify those populations already exposed to high temperatures that may be at risk of decimation by ...

Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics

open access: yesJournal of Animal Ecology, Volume 90, Issue 7, Page 1623-1634, July 2021., 2021
Using tank‐bromeliads, the authors experimentally investigated for the first time how aquatic–terrestrial linkages are affected by warming in the tropics. In contrast to temperate regions, warming is predicted to cause strong declines in tropical aquatic insect emergence into terrestrial ecosystems, while variably affecting terrestrial detritus ...

‘Blue-’ and ‘Brown-speckled’ pottery from Qalhât, the Sultanate of Oman (13–16th centuries): Comparison with traditional Omani 19–20 century productions

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2022
Representative ‘Blue speckled’ (13–16th centuries) and ‘Brown speckled’ (13–21st century) wares recovered from the excavations in Qalhât or collected around Bahlâ city (Sultanate of Oman) were characterized by XRPD, SEM-EDS, Raman/optical ...

Hydrodynamic Analysis of the Flow inside the Submerged Entry Nozzle

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
The quality of steel produced by continuous casting depends mainly on the characteristics of the liquid steel flow pattern within the mold. This pattern depends on the flow dynamics of the nozzle that is immersed in liquid steel. This work characterizes the fluid dynamics within two separate submerged entry nozzle models with a square cross section ...
