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

Marbled polecat

Vormela peregusna

Vormela peregusna

Some facts about this mammal:

Body length: 27–38 cm.

Tail length: 12–22 cm.

Weight: 260–520 grams.

Habitat: Dry open spaces; sometimes found in bushes and forest edges of semi-arid areas.

Distribution: From southeast Europe to Russia and China.

Diet: Chiefly feeds on rodents, occasionally on small birds, lizards, fish, frogs, snails, and insects.

Surviving number: Unknown.

Conservation status: Vulnerable (IUCN 3.1)

First described: By the German naturalist and explorer Johann Anton Güldenstädt in 1770, originally named as Mustela peregusna.


Vormela peregusna wears a very special perfume: when it is threatened, it throws its head back, displays its coloring and emits a noxious defensive odor. If all this doesn't have the desired effect, it just drops down and plays dead. This elusive hunter employs offensive strategies as well, such as approaching and attacking from the side. By using such techniques, it can overcome pray larger than itself during its forays at dusk, dawn, and throughout the night. The marbled polecat has nevertheless more trouble than it can handle in one realm: its steppe habitat is shrinking in Europe and Asia making this species status vulnerable.
