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.

Jirafa

La jirafa (Giraffa camelopardalis) es el animal terrestre más alto de la Tierra, puede alcanzar 5,5 metros de altura y pesar hasta 1.750 kg. Su elongado cuello, que contiene las mismas siete vértebras cervicales que todos los mamíferos, evolucionó para alimentarse de acacias en sabanas y bosques africanos. Animal social que vive en manadas sueltas, se comunica mediante infrasonidos y lenguaje corporal. Clasificada como Vulnerable debido a la pérdida de hábitat y la caza furtiva.
