How do centipedes and millipedes respond to grazing intensity in an integrated crop-livestock system with soybean-pasture succession? [PDF]

Revista Brasileira de Ciência do Solo
Centipedes and millipedes promote important functions in the ecosystem. However, land use intensification in agricultural areas can reduce the abundance and diversity of these organisms.

Oxygen consumption from air and water, ammonia and urea‐N excretion, and Na+ fluxes during progressive aquatic hypoxia in Amazonian armoured catfish Pterygoplichthys gibbiceps and Pterygoplichthys pardalis

Journal of Fish Biology, Volume 108, Issue 3, Page 867-880, March 2026.
Abstract The Amazonian loricariid fish Pterygoplichthys gibbiceps, from the Rio Negro, and Pterygoplichthys pardalis, from the Rio Solimões, are facultative air‐breathers that can use the stomach as an air‐breathing organ. Measurement of oxygen uptake under progressive aquatic hypoxia revealed a relatively high hypoxia resistance of both species.

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

Journal of Fish Biology, Volume 108, Issue 3, Page 881-893, March 2026.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

Assisted recovery of tissue loss in massive corals Orbicella faveolata: an alternative conservation tool for restoring damaged colonies

Restoration Ecology, Volume 34, Issue 3, March 2026.
Abstract Introduction Coral reefs, vital for marine ecosystems and human well‐being, face drastic decline due to climate change effects. In the Caribbean, global disturbances and regional water pollution exacerbate conditions, eliciting disease outbreaks that, in synergy with coral bleaching and hurricanes, cause significant damage to key reef‐building
