In the book Niche Construction: The Neglected Process in Evolution [Error: Wrong macro arguments: "http://zotero.org/users/438144/items/7NJ4SSM9" for macro 'ref' (maybe wrong macro tag syntax?)] the authors use examples from the book Journey to the Ants [Error: Wrong macro arguments: "http://zotero.org/users/438144/items/6GX882QH" for macro 'ref' (maybe wrong macro tag syntax?)] to illustrate ecosystem engineering. Though the examples from the New World ants might be more impressive, European and do significant ground work too.
