Threatened flora and forest in the Azores

The authors visited the Azores in September 1986 to investigate the status of the archipelagos natural forests and the rare endemic trees they contain. They carried out intensive investigation only on the island of Pico, although they also worked on Terceira and Sao Miguel. These three are the only islands on which moderately large areas of forest are believed to remain.

The role of the North Atlantic Oscillation in controlling U.K. butterfly population size and phenology

1. The North Atlantic Oscillation (NAO) exerts considerable control on U.K. weather. This study investigates the impact of the NAO on butterfly abundance and phenology using 34 years of data from the U.K. Butterfly Monitoring Scheme (UKBMS).

Ocean acidification needs more publicity as part of a strategy to avoid a global decline in calcifier populations

Ocean acidification (OA) is caused by increasing atmospheric concentrations of carbon dioxide, which dissolves in seawater to produce carbonic acid. This carbonic acid reduces the availability of dissolved aragonite needed for production of some invertebrate exoskeletons with potentially severe consequences for marine calcifier populations. There is a lack of public information on OA with less than 1% of press coverage on OA compared with climate change; OA is not included in UK GCSE and A Level specifications and textbooks; environmental campaigners are much less active in campaigning about OA compared with climate change. As a result of the lack of public awareness OA is rarely discussed in the UK Parliament. Much more public education about OA is needed so that people can respond to the urgent need for technological and lifestyle changes needed to massively reduce carbon dioxide emissions.

A game demonstrating aspects of bumblebee natural history

The Bumblebee Game is an exciting outdoor game, which demonstrates aspects of bumblebee natural history including food chains, food webs and competition for food, predation by crab spiders, parasitism by Conopidae (Diptera) and brood parasitism by cuckoo bees. It has been played successfully with groups of 10–25 people. Although most suitable for 6–14 year olds, adults have had a lot of fun playing this game.
