Choke

Choke (Epichloe typhina) is an endophytic and pathogenic fungus in the family Clavicipitaceae, phylum Ascomycota, that colonises the tissues of various cool-season grasses (Poaceae) across Europe and North America. The name refers to the disease it causes — infected grass tillers are typically 'choked' (prevented from flowering) when the fungus produces a dense, white to cream-coloured, stromata (a compact fungal structure) that surrounds the flowering stem before it can emerge, suppressing seed production. Epichloe species exist along a mutualism-parasitism continuum; some strains are biotrophic endophytes living almost entirely within grass tissues without obvious symptoms and conferring benefits to the host such as increased drought resistance and deterrence of herbivores through alkaloid production, while others — including E. typhina — are more parasitic in nature, sterilising infected host tillers. The fungus spreads via airborne ascospores produced on its stroma that infect new host plants. Related Epichloe/Neotyphodium endophytes are of great practical importance to agriculture as they produce ergot alkaloids and other compounds that can cause toxicosis in livestock grazing infected pasture grasses. As a fungal pathogen/endophyte rather than a wildlife species, it is Not Evaluated by the IUCN.

호주 동부와 동남부의 상징적인 유대류로, 체중이 최대 15kg이며 저칼로리인 유칼립투스 잎 식단에서 에너지를 절약하기 위해 하루 최대 22시간을 잠으로 보낸다. 대부분의 다른 포유류를 죽일 수 있는 유독한 유칼립투스 성분을 처리하도록 고도로 특화되어, 해독에 특별히 적응된 장내 미생물총을 지닌다. 2022년 기후 변화, 서식지 개발, 클라미디아 감염으로 인한 개체수 감소로 위기종으로 지정되었다.
