Many marsupials undergo torpor as well as some birds and placental mammals. [26] There are two types of torpor: hibernation which is long term (weeks or months) and daily torpor which is usually only a few hours. [26] Daily torpor involves a less extreme lowering of body temperature and metabolic rate than hibernation. Antechinus undergo daily ...
An early birth removes a developing marsupial from its mother's body much sooner than in placentals; thus marsupials lack a complex placenta to protect the embryo from its mother's immune system. Though early birth puts the newborn at greater environmental risk, it significantly reduces the dangers associated with long pregnancies, as the fetus ...
Quolls are mostly carnivorous. The smaller quolls primarily eat insects, birds, frogs, lizards and fruit; the larger species eat birds, reptiles, and mammals, including echidnas and possums. The spotted-tailed quoll's diet is dominated by mammals such as brushtail possums, rabbits, hares and invertebrates.
Nectarivorous bats might be at particular risk of extinction due to their reliance on particular species of flowering plants. [18] A single marsupial species, the honey possum, feeds on nectar and pollen exclusively. It raises fewer young which grow more slowly than other marsupials of its size, because of the time-consuming effort of nectar ...
The kowari (Dasyuroides byrnei), also known by its Diyari name kariri, is a small carnivorous marsupial native to the gibber deserts of central Australia. It is the sole member of the genus Dasyuroides. Other names for the species include brush-tailed marsupial rat, bushy-tailed marsupial rat, kawiri, Kayer rat, and Byrne's crest-tailed ...
Frugivore seed dispersal is a common phenomenon in many ecosystems. However, it is not a highly specific type of plant–animal interaction. For example, a single species of frugivorous bird may disperse fruits from several species of plants, or a few species of bird may disperse seeds of one plant species. [3]
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The practice of restoring traditional names to marsupial species has conserved this common name. Gould referred to the species as the freckled antechinus, [5] and it has also been known as the speckled marsupial mouse. The online edition of Mammal Species of the World gave the name Southern dibbler in 2009. [12]
