🧬 New study!
How do mitochondria change across life? We tracked mtDNAcn within Zebra finches and found early-life decline and links of mtDNAcn to late-life flight performance

Abstract. Ageing is characterized by complex biological processes reflected in cellular and molecular changes. Mitochondria, which are crucial for energy p
We did not find any evidence of direct cytotoxicity on certain endocrine glands and/or of disruption of common molecular pathways associated with hormone chemical structure
The first paper of my PhD is now out in STOTEN
We carried out a systematic review and meta-analysis to evaluate the endocrine-disrupting properties of Hg exposure in wild birds, using hormone concentrations as a proxy for endocrine status
Great experience at the @eoufledglings.bsky.social meeting in Gdańsk #EOU26, presenting my research on seasonal changes in prolactin levels in magnificent frigatebirds and how mercury-induced disruption of this parental-care hormone may contribute to the emergence of disease outbreaks

However, we identified hormone-specific effects of Hg, including a significant negative association with thyroxine, and a significant positive association with triiodothyronine
Non-significant negative effects on baseline corticosterone and prolactin were also suggested
We provide a series of guidelines for future studies, highlighting current limitations and the importance of quantifying multiple hormones simultaneously in both sexes, during different reproductive stages while using the same biological matrix for both Hg and hormones
Incredible experience last month, sampling the magnificent frigatebird colony of Saint Giles Island (Tobago) for the first time ever to gather information about how latitudinal differences in environmental stressors might be driving disease outbreaks
