Yucca schidigera, also known as the Mojave yucca or Spanish dagger, is a flowering plant native to the southwest deserts of North America.
Description
Yucca schidigera is a small
The flowers are white, sometimes with a purple tinge, 3–5 cm (1+1⁄4–2 in) long (rarely to 7.5 cm), bell-shaped and segmented into six parts;[3] they are produced in a compact, bulbous cluster 60–120 cm (24–47 in) tall at the top of the stem. The fruit is an elongate berry, up to 11.5 cm (4.5 in) long.[4][5]
Distribution and habitat
The plant is native to the Mojave Desert, Chihuahuan Desert and Sonoran Desert of southeastern California, Baja California, New Mexico, southern Nevada and Arizona.[3]
This yucca typically grows on rocky desert slopes and
Fire ecology
Post fire, the Mojave yucca produces sprouts eagerly and the regeneration of the seedlings are witnessed.[6] The fire regime is defined predominantly by heavy crop vegetation that take part in carrying the fire in the ecosystem. Over time, the invasive species that have been introduced to the ecosystem, such as grasses, have turned more fire tolerant, increasing the fire frequency and altering the fire regime that existed in the past.
Early accounts describe the flora of the Mojave Desert as arid grassland and shrubland communities. This ecosystem depended on winter precipitation. Y. schidigera was tolerant of this fire regime and rarely harmed. However, the introduction of nonnative grasses led to a higher frequency of fire, which decreased the survival rate of Y. schidigera.
Uses
Moths gather pollen from the flowers and deposit it on the stigma of a flower, the ovary of which they lay their eggs in; the larvae eat of the fruit capsule as it grows, but leave behind some seeds to develop into fruit.[7]
The fibers of the Yucca schidigera leaves are used by Native Americans to make rope, cloth,[7] thread,[8] and sandals. The flowers and fruit are eaten either raw or roasted,[7] and the black seeds were ground into a flour. The roots are used to make soap.[7] Some reports claim that Native Americans wash their hair with yucca to fight dandruff and hair loss. Among the other maladies this yucca has been used to treat are headaches, bleeding, gonorrhea, arthritis and rheumatism.[9]
Currently, extracts from this plant are in animal feed and various
Researchers have also found that the ingestion of Y. schidigera have decreased the
In fish, Yucca schidigera extract is beneficial. It can improve the growth rate in fish as a result of increased protein metabolism, requiring less food to sustain populations of fish. Outside of boosted growth rates, Yucca schidigera can also be used to improve the health of fish as it reduces ammonia that may be present in the water, generally improving the water quality. Evidence also suggests that Yucca schidigera is a suitable substitute in enabling fish to fight off the many diseases that characterize aquaculture.[13]
