The Miners of South America: Impacts of Climate Change on the Distribution of Geositta Miners Along Elevational Gradients

Biotropica, Volume 58, Issue 1, January 2026.
We modeled the current and future distributions of seven Geositta species along elevational gradients in South America under two climate change scenarios. Our results show that most species are projected to lose suitable habitats, particularly under the high‐emission scenario, with distinct responses between lowland and highland taxa.

An approximation to the prediction of the summery emergence of "Ochlerotatus caspius" (Diptera: Culicidae) based on the relationship between degree-days accumulations and adult captures [PDF]

, 2006
Ochlerotatus caspius (Pallas) (Diptera, Culicidae) es el culícido más abundante durante el verano en las marismas de Huelva. Este estudio demuestra que la relación entre capturas de adultos, convertidas en probit, y la acumulación de temperatura o número

Exploring the Effects of Ultrasound Processing on Food Packaging Laminated With Aluminum Foil

Polymer Engineering &Science, Volume 65, Issue 12, Page 7136-7147, December 2025.
ABSTRACT This study investigates the effects of ultrasound (US) processing on laminated plastic packaging containing aluminum foil for food contact applications. Two multilayer structures, PET/Al/PE and PET/Al/PP, were exposed to US at 25 kHz and 8.75 W/L for up to 40 min at 25°C and 60°C, using a 3% acetic acid as a food simulant.

Microclimate refugia shape microclimatic niches and predict individual variability in post‐breeding migration in a partially migratory species

Journal of Animal Ecology, Volume 94, Issue 12, Page 2527-2541, December 2025.
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.

Sea surface temperature and the distribution and apparent abundance of skipjack (Katsuwonus pelamis) in the Eastern Pacific Ocean, 1951-1968 [PDF]

, 1970
ENGLISH: Isograms of sea surface temperature (OC) have been produced for 1949-1968 for the areas of the eastern Pacific Ocean in which the majority of the skipjack catch is taken. These are in the immediate coastal zone, California (35° N) to Chile (20 0
