Extinct Animals Pt2: Bramble Cay melomys

Their diet was primarily herbivorous, as they feasted on the limited vegetation of the cay, including plant materials and seeds. As nocturnal creatures, they adeptly navigated the night, seeking food and avoiding potential threats under the cover of darkness.
However, by around 2016, this species was declared extinct. The primary culprit behind this somber event was climate change, which led to rising sea levels. The increased water levels resulted in frequent inundations of their habitat, eroding the cay and leading to significant habitat degradation. As the waters rose, the available land shrunk, and with it, the vegetation that was crucial to the melomys' survival dwindled. This reduced food supply, coupled with the loss of shelter, made it nearly impossible for the species to sustain itself.
In addition to the direct impacts of climate change, the Bramble Cay melomys faced other challenges. Their restricted habitat meant that they had little to no chance of migrating or seeking refuge elsewhere when conditions became adverse. Furthermore, while human intrusions on the island were occasional, any such disturbances could have consequential effects on the small population. There's also the potential that predation by introduced species may have played a role in their decline.
The extinction of the Bramble Cay melomys is not just a tale of a species lost, but also a grim reminder of the cascading impacts of climate change on fragile ecosystems and the species that inhabit them. It underscores the urgency of addressing global environmental challenges, as even isolated pockets of life, like that on Bramble Cay, aren't spared from the overarching effects of a warming planet.
