Fauna of Scotland
Only six amphibians and four land reptiles are native to Scotland. The amphibians include three species of newt: the great crested, of which fewer than 1,000 individuals survive; the smooth, and the palmate. The other amphibians are the common toad, the natterjack toad, found in only four locations in the south-west, and the common frog. A single alien amphibian is known in Scotland, the Alpine newt, a recent escapee confined to the Edinburgh area.
Thomas Belt
In this book, he also first described the mutualistic relationship of certain Acacias and the ant we now know as "Pseudomyrmex spinicola". These are a species of red myrmecophyte-inhabiting neotropical ants which are found only in Nicaragua and Costa Rica. They live in the thorns of a tropical tree, "Acacia collinsii", feeding on nectaries along with the protein and lipid-rich pods produced by the plant for the ants and now known as Belsian bodies (or Beltian bodies) in honor of Belt.
