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

open access: yesNew Phytol
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.

Microclimate refugia shape microclimatic niches and predict individual variability in post-breeding migration in a partially migratory species. [PDF]

open access: yesJ Anim Ecol
The niche is characterized along a gradient of temperature and microclimate refugia. Individuals in breeding areas with low microclimate refugia availability are more likely to cover larger distances to post‐breeding areas, increasing exposure to risks.

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 ...

Composite Resin Preheating Techniques for Cementation of Indirect Restorations

open access: yesInternational Journal of Biomaterials, Volume 2022, Issue 1, 2022., 2022
Purpose. Resin‐based materials have been preheated by using different techniques and commercial devices. However, a consensus on the clinical protocol for cementing with preheated composite resins is lacking. The aim of this scoping review was to identify the different methods used for heating composite resins as used for cementing indirect adhesive ...

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 ...
