Antioxidant Defenses in the Kidneys and Heart of the Freshwater Fish Astyanax lacustris Subjected to High (31°C) and Low (15°C) Temperatures

Cell Biochemistry and Function, Volume 43, Issue 11, November 2025.
ABSTRACT Aquatic ecosystems have their abiotic and biotic factors constantly altered by various factors. Among them, water temperature is an abiotic factor that can significantly affect fish physiology, increasing energy demand, which can impact homeostasis and survival. Endocrine and metabolic changes and enzymatic modulation are referred to as stress

New insights into the biology of the rare ectoparasitoid rhopalosomatid wasps (Hymenoptera: Rhopalosomatidae) in the Neotropics: parasitoid–host relationships in Brazil and Costa Rica

Austral Entomology, Volume 64, Issue 4, November 2025.
Abstract Rhopalosomatidae (Hymenoptera, Vespoidea) are rare ectoparasitoid wasps that parasitize crickets (Grylloidea), with few records documented in the literature, which originate from the Nearctic and Australian regions. Here, we report the first record of Rhopalosomatidae larvae parasitizing crickets of the family Phalangopsidae in the Neotropics.
