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.

Jaguar

El felino más grande de las Américas, alcanzando hasta 100 kg con una constitución robusta y musculosa y un pelaje con rosetas características. Se encuentra desde México hasta América del Sur, con núcleos poblacionales en el Amazonas y el Pantanal. Nadadores poderosos y depredadores apex, los jaguares desempeñan un papel fundamental en la regulación de las poblaciones de presas. Categorizado como Casi Amenazado, su área de distribución se contrae debido a la deforestación.
