The People's Trust for Endangered Species is awarding funding for students/recent graduates who wish to gain experience by taking up an internship with conservation or research organisations - details available here.
For work with invertebrates, two internships are available this year, deadline for applications is 15 June 2009. Mammal internships have been allocated for 2009 but will be available again in 2010 (I see that there are seven mammal internships available, which is a bit unbalanced given the relative number of species to choose from, but far be it from me to criticise funding for worthwhile causes!).
(I'm indebted to the Amateur Entomologists' Society for information on these awards, via the AES Twitter feed.)
