Island biogeography is an important subject for
several reasons. First, it has been and remains a
field which feeds ideas, theories, models, and tests
of same into ecology, evolutionary biology, and biogeography.
This is because islands provide natural
scientists with model systems—replicated and simplified
contexts—allowing us to isolate particular
factors and processes and to explore their effects.
This short book is about conserving insects, the most diverse and abundant
animals that share our world. In particular, it is about the common
focus of conserving individual species of insects. This so-called ‘fine filter’
(or ‘fine grain’) level of conservation parallels much conservation effort
for better-understood groups of animals such as mammals and birds,
for which species-focused conservation exercises are commonplace.
Nowadays, environmental issues including air and water pollution, climate
change, overexploitation of marine ecosystems, exhaustion of fossil resources,
conservation of biodiversity are receiving major attention from the public,
stakeholders and scholars from the local to the planetary scales. It is now
clearly recognized that human activities yield major ecological and environ-
mental stresses with irreversible loss of species, destruction of habitat or cli-
mate catastrophes as the most dramatic examples of their eﬀects.
