Rusa

Rusa Alfredi(Visayan Spotted Deer)

Rusa Marianna (Philippine Deer

Rusa Timorensis (Sunda Sambar)

Rusa unicolour (Sambar)

These deer’s feed at night, they eat fruits, cogon grass and young leaves and buds found near the forest floor. They also lick on the ashes from burned forest clearings, it is said that Rusa’s do this because they receive minerals from the ashes.

Food web

Deer live in a variety of different biomes, from tundras and tropical rainforests. Some deer live in transitional areas between forests and thickets (for cover) and prairie and savanna (open space). The majority of deer live in temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest, and savanna habitats around the world.

Biome

Since deer are herbivores they only eat plants and so its main competition is with other grass eaters for food.

Competition

There are four species of Rusa’s:Rusa alfrediRusa mariannaRusa timorensisRusa unicolor

Biodiversity of Rusa

Domain: EukaryaKingdom: AnimaliaPhylum: ChordataSubphylum: VertebrataClass: MammaliaOrder: ArtiodactylaFamily: CervidaeSubfamily: Cervinae

Scientific Classification

 Early animalia is the Flagellated Eukaryote. Early chordata is the Kimberella.Early vertebrata is a Myllokunmingia. Earliest origin of mammalia is the

Sinconodon.There is not an earliest origin for artiodactyla

but it is split inot three groups and deer is in the Ruminantia group.

Adaptive radiation

The earliest fossil deer date to the Oligocene of Europe. Later on some species were found larger, with more impressive antlers. They rapidly spread to other continents. Some extinct deer had huge antlers, larger than those of any living species. Examples Eucladoceros and Megaloceros.

Syndoyocera, Dicrocerus elegans, Archaeomeryx are three of the first animals that are considered to be related to the deer.

Evolution of Rusa

Their coat can act like a camouflage in the woods

They can run fastTheir sense of smell also protects them from

harmThey have long necks that help them see

predators from a distanceTheir eyes help them see in the darkThey can hear predators approaching

Adaptations Found in Rusa

Primary and Secondary Succession would affect these organisms by a lot. Deer genus’s are herbivores so they eat herbs such as grass, weeds and etc,. If there is no soil these herbs cannot grow and if there is no food then there is no point of the deer’s being there. When Secondary Succession happens there is soil but there are no plants. Because there are no plants there is no vegetation for the deer.
