These two sympatric congeners are key components of the jarrah forest and share pollinators and seed dispersers, but contrast markedly in their population densities.
By controlling the timing of flowering through irrigation or managing domesticated bee hives, farmers effectively reduce the dependency on nearby forest cover for pollinator services irrespective of the distance between forests and agro-forests, but these management practices incur costs that not every farmer can cover.
In other words, tree assemblages in this habitat appear to carry a narrower range of floral traits and pollination systems in comparison to patches of forest interior, particularly for pollinators such as mammals and hawkmoths (reduced support capacity).
To better understand climate change impacts this chapter explores three diverse assemblages of insects—(1) forest insect herbivores, (2) pollinators and other flower visitors, and (3) insects of freshwater ecosystems.
We attribute this to the small-scale staggered flowering of irrigated agro-forests resulting in the concentration of pollinators at these sites regardless of its proximity to forests or the size of nearby forest.
We investigated the combined effect of distance from forest and forest size on pollinator abundance at coffee agro-forests in Kodagu District, India, under two contrasting flowering scenarios: irrigation triggered flowering in a single agro-forest, and rain triggered flowering at all the remaining agro-forests that received rain but were not previously irrigated.
It has been recently suggested that Amegilla may be the most important pollinator in the forest understory [ 31- 33], particularly in the Oriental (Indomalayan) region [ 31].
Therefore, the similar responses of native plant and native pollinator species to forest area caused a positive relationship between forest area and the numbers of links at the same spatial scale (i.e., 820 m; Figures 6b 7b).
And it's their tendency to keep bug populations down and plant populations up (they act as pollinators in the rain forest) that makes them good friends to man.
Invertebrates are a vital component of forest biodiversity, functioning as decomposers and pollinators, herbivores, predators and prey.
