- Ecological and evolutionary legacy of megafauna extinctions
Here we use body-mass based scaling and range maps for extinct and extant mammal species to show that these extinctions led to an almost seven-fold reduction in the movement of gut-transported microbes, such as Escherichia coli (3 3 km2 day to 0 5 km2 day)
- Biogeography of time partitioning in mammals - PNAS
We cross-referenced our dataset with a published species-level mammal phylogeny (61, 62) To avoid circular reasoning, we omitted species from the phylogenetic analysis for which we had interpolated activity pattern on the basis of family, order, or genus without species-specific information (with the exception of bats)

- From Alpacas to Yaks, Mammal DNA Yields Its Secrets
The Zoonomia data set has limitations It contains just one genome per species (with the exception of the domestic dog, which was sequenced twice), and thousands of mammals are missing
- Armadillo - Wikipedia
Today, all extant armadillo species are still present in South America They are particularly diverse in Paraguay (where 11 species exist) and surrounding areas Many species are endangered Some, including four species of Dasypus, are widely distributed over the Americas, whereas others, such as Yepes's mulita, are
- List of domesticated animals - Wikipedia
A number of factors determine how quickly any changes may occur in a species, but there is not always a desire to improve a species from its wild form Domestication is a gradual process, so there is no precise moment in the history of a given species when it can be considered to have become fully domesticated
