On the #biology of #rockwallabies of the genus #Petrogale and the #faecal #microbiome of the #yellowfooted #rock #wallaby. Rock wallabies are widespread in northwestern, eastern, and southeastern #Australia and, unlike other #kangaroo #species, are mostly not severely threatened. Seventeen species are recognized, most of which are medium-sized and distinguished by their ability to climb and jump in #rockyterrain. These nocturnal animals possess special #adaptations to their rugged #environment. The pads of their hind feet are particularly thick, providing better grip on the rocky ground. The tail primarily serves to maintain balance during #jumps, which can reach distances of more than 4 meters. Like all kangaroos, these species are herbivores and can be very frugal when #food is scarce, even subsisting on bark if necessary. It is suspected that their habitat is responsible for the fact that the animals are less threatened in their populations, because they do not occur in areas where they could become food competitors with livestock. #Sistergroup, thus the closest phylogenetic relatives of the rock wallabies are the #treekangaroos of genus Dendrolagus. The authors L. E. Werner et al. (2025) investigated the faecal microbiome of Petrogale #xanthopus xanthopus. In addition to the faecal microbiome, they also examined its relationship to #diet and #season/rainfall. The studies were conducted using two #populations of this species native to two separate, ecologically differing regions of South Australia. The researchers found that (citation) "Sequencing targeting the 16S rRNA gene revealed that location was the greatest driver of faecal microbial differences (P < 0.01), with season (P < 0.01) and the interaction of location × season also statistically significant (P < 0.01)." According to the authors, knowledge of a species' microbiome is important e.g. for implementing #conservation measures particularly in the context of #globalwarming. © #StefanFWirth Berlin December 2025 References: Video about rock wallabies: Australian Geographic on X (2025): https://t.co/T1t01zYLZe L.

🤔 #AcademicTwitter, any wild guesses 🙄about what called this maze of electric wires a nest location? Zoom in 🧐to find the outcome of #Green vs #Grey . A female incubates around what can be termed as kissing #death every second. #YellowFooted #ornithology @wii_india @egioxford
