Tropical butterflies use thermal buffering and thermal tolerance as alternative strategies to cope with temperature increase

open access: yesJournal of Animal Ecology, Volume 92, Issue 9, Page 1759-1770, September 2023., 2023
Tropical butterflies with a stronger ability to thermoregulate have lower thermal tolerance, and vice versa. This implies that species adapt to climate change using one strategy at the expense of the other, and many tropical butterflies may be at risk.

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.

Direct gas heating in linear concentrating solar collectors for power and industrial process heat production: Applications and challenges

open access: yesWIREs Energy and Environment, Volume 12, Issue 4, July/August 2023., 2023
Linear concentrating collectors heating gases for power (concentrating solar power) or industrial process heat production (solar heat for industrial processes) Abstract Parabolic trough collectors and linear Fresnel collectors are mature technologies for power production, and they are being recently applied to provide solar heat for industrial needs ...

Interspecific differences in microhabitat use expose insects to contrasting thermal mortality

open access: yesEcological Monographs, Volume 93, Issue 2, May 2023., 2023
Abstract Ecotones linking open and forested habitats contain multiple microhabitats with varying vegetal structures and microclimatic regimes. Ecotones host many insect species whose development is intimately linked to the microclimatic conditions where they grow (e.g., the leaves of their host plants and the surrounding air).

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics

open access: yesGlobal Change Biology, Volume 29, Issue 2, Page 308-323, January 2023., 2023
Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

Characterization of seasons over the extratropics based on the annual daily mean temperature cycle

open access: yesInternational Journal of Climatology, Volume 42, Issue 11, Page 5570-5585, September 2022., 2022
Seasons characterization from temperature annual cycle over extratropical regions. Abstract A proposal to characterize seasons based on the annual cycle of daily mean temperature over extratropical regions is presented. Four metrics are computed, based on the dates along the year when the maximum and minimum temperature values and the maximum warming ...

Estudio del régimen de combustión sin llama ante la variación de la carga térmica

open access: yesIngeniería y Ciencia, 2017
El presente estudio evaluó numérica y experimentalmente en un horno de 20 kW (a gas natural y con un factor de aireación de 1,2) la estabilidad del régimen de combustión sin llama ante la variación de la carga térmica usando diferentes flujos de aire (43

Direct Observation of Vortex Liquid Droplets in the Iron Pnictide Superconductor CaKFe4As4 at 0.5Tc

open access: yesAdvanced Science, Volume 13, Issue 48, 28 August 2026.
Vortex matter in the iron‐based superconductor CaKFe4As4${\rm CaKFe}_4{\rm As}_4$ is visualized at the nanoscale, revealing the unexpected emergence of vortex‐liquid droplets far below the critical temperature. These localized fluctuating regions coexist with a vortex solid, demonstrating that dissipation‐related dynamics arise well before macroscopic ...
