저명한 생물학자

Adriana Hoffmann Jacoby
Born 1940. Standard IPNI form: A.E.Hoffm.

As a Chilean botanist and environmentalist, Adriana Hoffmann Jacoby has authored over a dozen books on the flora of Chile and has identified and classified more than 100 new species of cacti. She was Chile's Environment Minister in 2000 and 2001. She has advocated for the sustainable management and protection of Chilean forests, leading opposition to illegal logging in her role as coordinator of Defensores del Bosque Chileno (Defenders of the Chilean Forest) since 1992.

Hoffmann was recognized by the United Nations in 1997 as one of the 25 leading environmentalists of the decade for her efforts to protect Chile's forests. In 1999 she won the National Environmental Prize in the category of Environmental Education, awarded by Comisión Nacional del Medio Ambiente (CONAMA). For her research into Chilean flora and her work in environmental education, Hoffmann received the Luis Oyarzún Award from the Austral University of Chile in 2003. She received a Fellow Award from the Cactus and Succulent Society of America in 2009.

Hoffmann has also served on the judging panel for the United Nations Environment Programme's Sasakawa Prize.

Species of the month

Danaus plexippus

Danaus plexippus

Some facts on this insect:

Wingspan: 8.9–10.2 cm.

Range: North America to 50°N in summer, migrating south to California and Mexico to over-winter; also Canary Islands, Madeira, Azores, Bermuda, many Pacific islands, including Galapagos Islands, Hawaii, New Zealand, Australia, Moluccas, Philippines, Taiwan.

Habitat: Can be found in a wide range of habitats such as fields, meadows, prairie remnants, urban and suburban parks, gardens, and roadsides.

Adult diet: Flower nectar.

Larvae diet: Milkweed leaves.

Life-span: 2 to 8 weeks; hibernating generation: 6 to 8 months.

Conservation status: Near Threatened (IUCN 3.1).

First described: By the Swedish naturalist Linnaeus in 1758.


Danaus plexippus just loves travelling. This butterfly is the only insect which migrates up to 4,000 km., from Canada to Mexico and Baja California and back again, to reach warmer weather and to hibernate. Only the fourth generation migrates each year. The first three generations live only a few weeks, while the forth continues to live on for up to six or eight months so that they can migrate to a warmer climate, hibernate, and start a new first generation in the springtime when they return. The monarchs are poisonous from the milkweed plant chemicals that the larva eat. This creates a defense against predators like frogs, birds, mice and lizards. Recent deforestation of the monarch's overwintering grounds have led to a drastic population decline. Efforts to classify it as a protected species and to restore its habitat are under way.
