Figure 1 in Predation of the black-eared opossum (Didelphis aurita) on the great kiskadee (Pitangus sulphuratus) and the water rat (Nectomys squamipes)
Figure 1: Predation of Pitangus sulphuratus by Didelphis aurita at the Institute of Biodiversity and Sustainability, Macaé, Rio de Janeiro, Brazil. (A) A young individual of P. sulphuratus sleeps on a top of a box on the ground. (B) D. aurita appears in the video in a sinuous way being guided by smell. (C) The opossum moves behind the young P. sulphuratus, which shows no reaction. (D) D. aurita walks towards the P. sulphuratus individual. (E) D. aurita attacks young P. sulphuratus by grabbing it with its front limbs. (F) The opossum makes a fatal bite on the bird.

Figure 2 in Opossums cleaning our cities: consumption of rodent carcasses in an urban reserve
Figure 2: Schematics of the trophic interactions around a rodent carcass (percentages indicate the proportion of consumed carcasses). Note that flies are consumed by lizards (as adults) and by possums and ringtails (as eggs and larvae); however, there is no consumption of ants by any animal in this net.

Histological stacks for: Vestigial structures and variation in the evolution of the marsupial mammal dental development: A study of the Woolly Opossum Caluromys philander
<p>The pattern of dental replacement in marsupial mammals has received much attention for its derived nature and potential relationship to the life history of the group. However, few species have been studied thoroughly and little is known about the embryonic structures and their use in addressing issues of homology and dental evolution in general. We studied a developmental series of ten individuals of pouch young Caluromys philander to thoroughly document dental development with histological sections and 3D models of dental series.</p> <p>This dataset contains the raw TIFF stacks for the above histological sections. These may be used for direct histological analysis, or to generate 3D-reconstructions using software such as Fiji and TrakEM2.</p>
