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

Common European Glowworm

Lampyris noctiluca

Lampyris noctiluca (Linnaeus, 1758)

Some facts about this beetle:

Average Size: The adult female is 12–20 mm long, while males rarely grow longer than 10 mm. The larvae are often only a few milimeters long.
Protection status: Not assessed.
Diet: Even though they are small in size the larvae are fierce carnivores, roaming leaf litter in search of tiny slugs and snails. Adults rarely feed at all.
Range: From Portugal and Britain in the west, right across Europe and Asia to China in the east. It also survives further north than any other firefly, almost reaching the Arctic Circle. For example, it is fairly common in south- and central Sweden and southern Finland.
Strange fact: The light of this firefly is actually cold light, producing very little wasted heat. When glowing only 2–10 percent of the energy is wasted as heat, while a whopping 90–98 percent of the energy is converted into light. This makes the process much, much more energy efficient than any light sources ever manufactured by humans.
