Habitat & Geographic Range
Christmas Fern Leaf Curl
Native to North America, inhabiting ecosystems characteristic of the region.
Found in United States.
Green Sea Turtle
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 8 distinct biome types. Populations are also found in montane and highland environments at higher elevations.
Distributed across Australia, Brazil, Costa Rica, Indonesia, and Mexico. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.
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.
Green Sea Turtle
La tortuga verde (Chelonia mydas) es una de las tortugas marinas más grandes. Su nombre proviene del color verde de su cartílago y grasa, no del caparazón.
