Abstract

We report a rare behavioral observation involving an individual of Chionis alba (snowy sheathbill) attempting to consume a basidiome of the toxic mushroom Galerina marginata on Livingston Island, Antarctica. The bird briefly picked up the basidiome before rejecting it. This event, to our knowledge, represents the first recorded interaction between an Antarctic bird and this deadly fungus, suggesting possible chemical or gustatory deterrence mechanisms. Such interactions, though anecdotal, contribute to the understanding of trophic dynamics and fungal ecology in polar environments.

南极雪鞘喙菌与产蛋黄素的蘑菇Galerina marginata的探索相互作用。

我们报告了一个罕见的行为观察，涉及到一只Chionis alba（雪鞘喙）个体试图消耗有毒蘑菇Galerina marginata的担子子。这只鸟短暂地捡起了担子架，然后拒绝了它。据我们所知，这一事件代表了南极鸟类与这种致命真菌之间首次有记录的相互作用，表明可能存在化学或味觉威慑机制。这种相互作用，虽然道听途说，有助于理解营养动力学和真菌生态在极地环境。

期刊介绍： (aka Journal of Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases -- MEEGID) Infectious diseases constitute one of the main challenges to medical science in the coming century. The impressive development of molecular megatechnologies and of bioinformatics have greatly increased our knowledge of the evolution, transmission and pathogenicity of infectious diseases. Research has shown that host susceptibility to many infectious diseases has a genetic basis. Furthermore, much is now known on the molecular epidemiology, evolution and virulence of pathogenic agents, as well as their resistance to drugs, vaccines, and antibiotics. Equally, research on the genetics of disease vectors has greatly improved our understanding of their systematics, has increased our capacity to identify target populations for control or intervention, and has provided detailed information on the mechanisms of insecticide resistance. However, the genetics and evolutionary biology of hosts, pathogens and vectors have tended to develop as three separate fields of research. This artificial compartmentalisation is of concern due to our growing appreciation of the strong co-evolutionary interactions among hosts, pathogens and vectors. Infection, Genetics and Evolution and its companion congress [MEEGID](http://www.meegidconference.com/) (for Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases) are the main forum acting for the cross-fertilization between evolutionary science and biomedical research on infectious diseases. Infection, Genetics and Evolution is the only journal that welcomes articles dealing with the genetics and evolutionary biology of hosts, pathogens and vectors, and coevolution processes among them in relation to infection and disease manifestation. All infectious models enter the scope of the journal, including pathogens of humans, animals and plants, either parasites, fungi, bacteria, viruses or prions. The journal welcomes articles dealing with genetics, population genetics, genomics, postgenomics, gene expression, evolutionary biology, population dynamics, mathematical modeling and bioinformatics. We also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more.
