Reproduction in herbivore species is generally timed to coincide with the peak growth period of plant populations (their food resources). If the timing of reproduction in herbivore species and the peak growth of plant populations repsond differently to changing climate conditions, how might this influence the interaction between herbivores and their food resources?

Answer #1

Many insect species have co-evolved their reproductive behaviors with respect to their habitat conditions.

It is given that certain species of insects reproduce during the peak growth period of plant populations. This helps the insect to get more food and better survival rates for their progeny.

If climatic conditions change and high plant growth rate season shifts to a different season,

i. The insect species will be negatively affected as food resources will be less during their reproductive season. Their progeny also find it difficult to get food and escape from predation.

ii. If the insect population co-evolves with the plant community (shifting its reproductive season), then it can survive. Otherwise, the insect species may become extinct.

Plant growth provides food for herbivores that in turn can impact the productivity of the ecosystems that they graze. Herbivores remove green leaves and therefore lower potential whole-ecosystem photosynthesis by reducing the leaf area index. However herbivores may also reduce the amount of shading in the lower plant canopy and fertilize soils with their feces and urine, increasing the amount of light and nutrients for the remaining uneaten plants. Removal of leaves by herbivores may also warm up soils, leading...

Fueling Indonesians: Window of Opportunity or Regret? Kerosene is widely used as cooking fuel by Indonesian households, with an annual usage of 10 million Kiloliters. It is a major subsidized fuel for household cooking, where its usage is over sixty percent of the 230 million population. The subsidy program costs the government heavily, where it amounts up to U.S.$4 billion a year. As the practice tends to bleed government expenditures quite heavily, the Indonesian government is embarking on a change...
