Our study aims to reveal the histophysiology of adrenal glands and gonads in relation to hormone levels and discover the impact of anthropogenic activities on the stress and reproductive hormones in wild brown bears.
In morphology and histophysiology of the adrenal and reproductive glands of a brown bear, there are certain knowledge gaps which are to be clarified. Furthermore, how the adrenal glands modulate the architecture and physiology of gonads in different seasons including reproductive season is also unknown. Uncovering these physiological phenomena will help to increase the fundamental understanding of the brown bear’s reproductive biology and the role of adrenal glands in the context of reproductive fitness. To carry out the study, histological, immunohistochemical, and electron microscopy techniques will be applied. Electronograms revealing the ultrastructure of glands and their secretional capacity will be analyzed in relation to other measured stress and reproductive indices. Samples for this study will be obtained from Croatia during trophy hunting seasons.
Ghulam Nabi joined the Polish Academy of Sciences in 2022. His research focuses on the ecophysiology of mammals. He completed his master's degree in Endocrinology in Pakistan and earned a PhD degree in Hydrobiology from the University of the Chinese Academy of Sciences. Afterwards, he continued his postdoctoral research in avian endocrinology and physiology at Hebei Normal University in China and was appointed associate professor there.
