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

Agile Gibbon

Hylobates agilis

Hylobates agilis

Some facts on this ape:

Head and body length: 45–65 cm.

Weigth: Males: 5–7.5 kg.; females: 4.5–7.3 kg.

Habitat: Semi-deciduous (trees that lose some of their leaves seasonally) monsoon and tropical evergreen forest.

Distribution: Indonesia on the island of Sumatra, Malaysia, and southern Thailand.

Diet: Generally frugivorous but subsists also on leaves, flowers, and insects.

Surviving number: Unknown, population declining.

Conservation status: Endangered (IUCN 3.1).

First described: By the French zoologist and palaeontologist Frédéric Cuvier in 1821.


Hylobates agilis is an able singer as well as an accomplished swinger. This gibbon begins its day with complex songs, including solos and male-female duets. The calls serve to advertise territory and the strength of the pair's bond. As to swinging, these primates use their long, powerful arms to swing rapidly from tree to tree in search of sweet fruit, immature leaves and insects. They contribute to the forest's health by dispersing seeds for next tree generations. As trees are being cut, the apes become vulnerable to habitat loss and fragmentation, and their songs may be silenced forever. The Agile Gibbon belongs to the family Hylobatidae (Gibbons) which includes 17 species.
