. According to the video and the background information, what are the effects (direct and indirect) that elephants have on acacias? (Select all that apply.)
Elephants can feed on and destroy individual acacia trees not protected by ants.
Browsing by elephants induces the acacias to provide food and shelter to the ants.
Loss of browsing by elephants eventually leads to the decrease of ant colonization of acacias.
Reduced nutritional and physical support of ants by acacias due to loss of browsing by elephants allows other ant species and stem-boring beetles to inhabit the trees.

Scenario 4: On your frequent trips to Costa Rica you have seen that there are certain trees that have
ants that live on them and the same species of trees without ants. Trees that have ants living on them
show little sign of being eaten by herbivores (deer, cows, etc.), but trees without ants are severely injured
by herbivores. You think that ants may protect these trees somehow from herbivores.

They pose an added threat to many native bee species already at risk of declining numbers or even extinction due to increasing urbanization. A research conducted in Australia has very recently published in the Biological Journal of the Linnean Society. According to the study, a competition between the native bees and the introduced European honeybee is particularly intense in residential gardens dominated by non-native flowers (the native bees have co- evolved to forage on) and occurred when the bees shared the same flower preferences. European honeybees, being very abundant, and effective foragers, with the ability to exploit a wide range of flowers, can outcompete native bees for nectar and pollen resources. In this condition, what would you suggest rescuing the native bees as a biotechnologist? Justify your reasoning.arrow_forwardBalancing palm harvest versus the incidental killing of parrots Now let's first evaluate whether harvesting palms at their optimal level can be tolerated by the parrot population, which is incidentally affected when palms felled inadvertently enclose nesting parrots. If the palm populations can be harvested in a sustainable manner at the same rate at which they can potentially grow, then what was the estimated maximum sustainable annual harvest rate for the palms? What was it for the parrots? Based on data originally given in the scenario, recall that the area is 10,000 km2, that 10 km2 hosts 1 parrot (of any age) and 1,000 palms, that felling every thousandth palm kills a nesting pair of parrots, and that carrying capacities for each species are twice their current densities. You now have all the information you need to address the question at hand: 12. If the palm population is harvested at its maximum sustainable limit, will the parrot population be at risk?
