Air exposure test in Colossoma macropomum juveniles maintained in water at suboptimal temperature: Physiological, metabolic and oxidative stress responses

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the physiological, metabolic and oxidative responses of Colossoma macropomum subjected to air exposure when maintained in water at suboptimal temperature (23°C). A total of 54 fish (81.33 ± 11.90 g) were distributed into nine tanks (6 fish per tank). For the air exposure test, 24 animals were exposed for 30 min and another

Invasive pine control promotes native plant regeneration, but with limited effect in the Cerrado, Brazil

Restoration Ecology, EarlyView.
Abstract Introduction Invasions by Pinus represent major challenges for conservation and ecological restoration, especially in open ecosystems of tropical South America, such as the Brazilian neotropical savanna (Cerrado). Objective We evaluated whether the clear‐cutting and manual removal of Pinus caribaea reduce the impacts of invasion on woody plant

Contrasting Osmotic Stress Responses and Provenance Effects on Seed Germination and Seedling Performance in Two Andean Species

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
Oreocallis grandiflora was highly drought‐sensitive, whereas Salvia corrugata recovered and showed adaptive traits. Provenance effects were strong in O. grandiflora but weak in S. corrugata. These results reveal species‐ and provenance‐dependent responses to water limitation, highlighting the importance of selecting suitable species and seed sources ...

How vulnerable are amphibians to climate change? A mechanistic perspective

Functional Ecology, Volume 40, Issue 6, Page 1550-1560, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Amphibians are frequently identified as highly vulnerable to climate change, yet the mechanisms driving this sensitivity remain uncertain. Approaches that explicitly link physiological mechanisms to environmental variation provide powerful tools for forecasting climate ...
