Interpretive Summary: As agricultural research organizations place more attention on climate change impacts it becomes informative to understand who is performing this research and the connectivity to other research groups in various countries. Using bibliographic information as a data source, we showed that countries primarily engaged (50% of all publications) in climate change impacts on livestock included: USA, China, Brazil, India, UK, Turkey, Germany, Egypt and Australia. Many scientists from developing countries lacked global connections, perhaps due to journal processing fees. It is suggested that research dealing with other avian species beside chickens needs strengthening.

Technical Abstract: Heat tolerance, especially under climate change scenarios, plays an increasingly import factor in pig and chicken production. We therefore evaluated bibliographic mapping of citation, co-occurrence of keywords, co-citation and bibliographic coupling for heat tolerance and these species. Data was obtained from Scopus (Elsevier) and analysed in Vosviewer. We found a total of 2023 documents from 102 countries, of which 10 countries account for 50% of the publications (USA, China, Brazil, Iran, India, UK, Turkey, Germany, Egypt and Australia). While heat tolerance is important worldwide, Global South countries, especially China, have become more prominent in publishing on this topic in recent years. Researchers from South America appear relatively isolated using the metrics of this study, with no clear explanation why, we speculate funding for publication may be a governing factor. The literature reviewed suggests an emphasis on mitigation strategies, that include nutrition and genetics. An emphasis in poultry for studying Gallus gallus was observed and suggests more attention is needed on other species (for example, ducks and turkey). Biases in the analysis could arise due to lack of citations from recent papers, those not indexed in Scopus or in other languages.
