When attacked by a dingo, a tamar wallaby is often trapped with its back up against a tree.  However, the fragmentation of its range has led to high amounts of inbreeding and morphological abnormalities in some populations. Cyanide pellets have been used as an alternative. Mainland Western Australian tammar wallabies appear to be the most resistant, while those on Kangaroo Island are much more vulnerable. Within the phylum Proteobacteria, species of the family Succinivibrionaceae are the most abundant and a new species named WG–1 was discovered. The tammar wallaby has been observed to engage in alloparental care, in which an adult may adopt another's young. Seit rund 1870 gibt es eine kleine Population auf der neuseeländischen Insel Kawau. :332 From the 19th century, tammar wallabies in the Eyre Peninsula and around Adelaide were decimated by mobs of hunters organised to protect crops and pastures.  The pinna (ear) of the tammar wallaby is mobile, allowing it to track sounds from different parts of its surroundings without moving its head. Vermutet wird eine Kombination aus verschiedenen Faktoren, darunter die Zerstörung ihrer Lebensräume zur Schaffung landwirtschaftlich genutzter Flächen, die Konkurrenz durch eingeschleppte Arten wie Kaninchen und Hausschafe und die Nachstellung durch eingeschleppte Räuber wie Hauskatzen und Rotfüchse. Das Derbywallaby, auch Tammar-oder Dama-Wallaby genannt (Macropus eugenii), ist eine Känguruart aus der Untergattung der Wallabys (Notamacropus). WG–1 is a capnophilic bacterium.
