Brown Rat

Brown Rat (Rattus norvegicus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.

cluster fig

Ficus congesta, a species within the enormously diverse fig genus of the family Moraceae, is a tropical tree producing characteristic clustered figs that ripen to attract frugivorous birds, bats, and mammals. The genus Ficus comprises over 800 species distributed pantropically, and F. congesta occupies forest habitats across Southeast Asia and Melanesia, where it grows in primary and secondary lowland tropical forests at varying elevations. Like other members of the genus, Ficus congesta maintains an obligate pollination mutualism with a specific fig wasp species in the family Agaonidae; each fig species and its wasp partner have co-evolved in tight specificity over millions of years. The tree produces figs in dense clusters on the trunk and branches, providing an abundant and reliable food source for wildlife that supplement more seasonal fruiting trees. Ficus congesta is assessed as Least Concern by the IUCN given the breadth of its range across Melanesia and parts of island Southeast Asia. Figs serve critical ecological roles as keystone resources in tropical forests, sustaining frugivore populations during periods when other fruits are scarce. The species contributes to forest regeneration as frugivores disperse its seeds widely across the landscape.
