HBL- Ecology by Stanley Yuan(30)

2) How has/will human activities in the Amazon regions affect the Allomerus decemarticulatus ants?

Human activities such as deforestation for land usage will affect the Allomerus decemarticulatus ants, causing their population to decrease. This is due to worker ants, which cut hairs from the stem of the plant they inhabit, and use the tiny fibers to build a spongy platform to catch unsuspecting prey. With the deforestation, the Allomerus decemarticulatus ants would have no food to eat as deforestation would destroy their traps. Furthermore, they will have a hard time adapting as there would be less plants for them to inhibit. Hence, human activities would affect the Allomerus decemarticulatus ants

3a) Predation, Allomerus decemarticulatus ants and their prey-Swarms of workers then rush over the hapless prey, stinging it into submission. The prone insect is then carted off towards the ants' home, a leaf pouch, where it is carved up

Commensalism, Allomerus decemarticulatus workers and Hirtella physophora. Allomerus decemarticulatus worker ants cut hairs from the stem of the plant they inhabit, and use the tiny fibers to build a spongy platform

Mutualism , Allomerus decemarticulatus worker ants and mould. The ants make holes in the platform and put in place pieces of sooty mould, which quickly grow around the structure and reinforce it.

3b) Predation - Cheetah & Thompson Gazelle
Commensalism - Epiphytes and Raintree
Mutualism - Clownfish & Sea anemone
