Dr. Stefanny C. M. Titon (Postdoctoral) and Dr. Vania R. Assis (egress) from the Graduate Program in General Physiology, were Guest Editors of the special issue "Ecoimmunology in Ectotherms" in the Journal of Experimental Zoology - Part A (JEZ-A). This SI brings ecoimmunology studies with a focus on ectotherms (fish, amphibians, and reptiles). The papers show the effects of the environment, hormones, sex, and age on the ectotherms immunology and updates on host-pathogen interactions that affect host immunity and survival. For an overview of all manuscripts, see the introductory paper they wrote by clicking on this link: https://doi.org/10.1002/jez.2437

Both are also authors of manuscripts within the SI. Dr. Vania presents immuno-endocrine differences in a gradient of South-North distribution of invasive cane toads (Rhinella marina) populations in Florida. The toads of the southern populations had a better baseline immune surveillance system (higher natural antibody titers and higher bacterial killing ability) and were more responsive to a new acute stressor (higher plasma corticosterone levels).

Dr. Stefanny shows differences in the thermal sensitivity of the bullfrog (Lithobates catesbeianus) immune response. Plasma bacterial killing ability (protein measure) showed thermal sensitivity, with higher values ​​found around 15°C. While the phagocytosis index (cell measure) did not show thermal sensitivity.
