Pelican Lagoon Research Centre. This is Peggy Rismiller's research center on Kangaroo Island, the premiere spot for Echidna research. Their website is a font information about echidnas and the other inhabitants of the island. Their DHTML menus, however, don't work in Mac IE, so I find their site extremely annoying to use...
Join the Echidna-work on Kangaroo Island. Earthwatch runs a program assisting Peggy Rismiller and her staff. The program is called "Echidnas and Goannas of Kangaroo Island," and is not free to join.
Natalie Mikecz's account of her experience on an Earthwatch echidna project, from Paddy Pallin, an Australian clothing merchant. Interesting account. Mikecz states "Despite over 200 years of research, little relevant knowledge is known of the echidna." I can't resist imagining that 200 years of research has yielded only irrelevant knowledge--the echidna's favorite Pez, perhaps, or how many echidnas will fit in a telephone booth.
Project Proposal: "Breeding Ecology and Conservation of Short-Beaked Echidnas". The American Zoo and Aquarium Association is sponsoring work on Kangaroo Island, Australia (the Pelican Lagoon Research Centre). Echidna export has been restricted since the 1970s, and echidnas don't breed well in captivity, so American zoos find echidnas in short supply.
Effort to save the Bruce/O'Connor Ridge in Canberra, includes a letter from Echidna researcher Peggy Rismiller and an extremely cute echidna close-up.
"Echidna Love Trains" from the Scribbly Gum program on Australian Broadcasting. This is hands-down the best single echidna page out there. The main focus is mating (including photographs of this delicate event), but the page brims with facts of all kinds and includes an eight-minute interview with Peggy Rismiller, a top echidna researcher. Includes a good Photo Gallery .

Monotremes and other relatives
Mesozoic Mammals? Monotremata, an internet directory by Trevor Dykes. This is an large and varied set of information and resources. Some links are dead. This is just one sub-page of his The Evolution of Mesozoic Mammals, a Rough Sketch, which includes many such directories. Dykes is to be congratulated for his prodigous efforts. He notes repeatedly that he is a hobbyist, not a scientist. I think there is significant value in popularizing, and in applying an educated layman's omniverous but discerning eye to topics like this.
