The paper examines heat stress and its adverse effects as a hindrance to profitable poultry production in the tropics, with emphasis on the Northern Guinea Savannah zone of Nigeria. It elucidates the general negative effects of heat stress on physiological parameters of domestic chickens, and the specific impact of the stress on reproduction in the tropics. The deleterious effects are expressed in poor poultry well-being and reproductive performance. It is concluded that measures aimed at alleviating heat stress in domestic chickens must be adopted in order to enhance reproductive and, consequently, efficiency of modern poultry production in the tropics.

Introduction: Thiamine-responsive megaloblastic anaemia syndrome (TRMA) is a rare genetic disease caused by mutations in the SLC19A2 gene that encodes thiamine transporter 1 (THTR-1). The common manifestations are diabetes, anaemia, and deafness. The pathogenic mechanism has not yet been clarified.

Global warming is intensifying heatwaves worldwide, leading to more frequent and severe temperature extremes. This study investigates the impact of the unprecedented 2022 Mediterranean heatwaves on the coral eukaryome, which has received little attention despite its known importance to coral holobiont functioning. Fifty-six colonies of the iconic red coral from the Mediterranean Sea were collected at different sites, depths, and health states.

Unlabelled: Calcium (Ca⁺) as a secondary messenger has a multidimensional role, including the growth and development of plants and the adaptive response to stress conditions. Calmodulin (CaM), a calcium-binding protein, uniquely binds with these Ca⁺ ions and transmits Ca⁺ signals. Calmodulin proteins have been well-reported in various plants for playing a role in abiotic and biotic stress signaling; however, a comprehensive analysis of the genes of Indian mustard () has not been studied much.

Unlabelled: (soybean) is a highly protein-rich legume that also contains oils and vitamins. Unfortunately, soybean faces many biotic and abiotic stresses including heat, drought, pests, wounds, infections, and salinity, which limits the crop productivity. Among these, mechanical wounding (MW) causes significant harm to plants, creates a passage for invading pathogens, and disrupts plant metabolism.

The extensive industrial use of lead (Pb) and chromium (Cr) has led to their persistent release into aquatic ecosystems, posing severe ecological and toxicological challenges. While the individual toxicities of these metals are well-documented, their combined effects, particularly on toxicity mechanisms and cellular stress responses, remain inadequately understood. This study investigated the hepatotoxic effects of Pb and Cr, both individually and in combination, in zebrafish (Danio rerio), focusing on oxidative stress and the Nrf2-Keap1-ARE signaling pathway.
