Christmas Fern Leaf Curl

The Christmas fern leaf curl (Olpidium polystichi) is a fungal pathogen in the family Olpidiaceae, occurring as a parasite on Christmas fern (Polystichum acrostichoides) and related host plants. Olpidium species are endobiotic chytrid fungi — organisms in the phylum Chytridiomycota — that complete their entire life cycle within the cells of host plant tissue, particularly in young, actively growing tissue. The disease caused by Olpidium polystichi on Christmas fern is associated with the characteristic curling, distortion, and stunting of developing fronds, giving rise to its common name. Chytrid fungi in the genus Olpidium are biotrophic parasites that form zoosporangia within host cells; these release motile zoospores that disperse in water films or free water to infect new host tissue. Many Olpidium species are also known as vectors of plant viruses, transmitting viral pathogens to host plants through their zoospores. The host specificity and ecological impact of Olpidium polystichi on Christmas fern populations are not extensively documented in the scientific literature. As a microscopic fungal pathogen, it is unlikely to cause significant population-level impacts on the widespread and robust Christmas fern under typical conditions.

Gorille de l'Ouest

The world's largest primate, western gorillas weigh up to 180 kg and inhabit the tropical and subtropical forests of equatorial Africa. Primarily herbivorous, living in family groups led by a silverback male who protects the troop and mediates social conflicts. Critically Endangered, with populations threatened by deforestation, poaching for bushmeat, and outbreaks of Ebola virus disease.
