Hawaiian forests grow on nutrient-poor, volcanic-derived soils that have Very low
phosphorus levels. In an experiment, scientists fertilized some areas of Hawaiian
forest with phosphorus. As a control, they left other areas unfertilized. After one
year, they observed increased tree growth on fertilized sites. Fertilized trees
supported 37% more herbivorous insect biomass than unfertilized trees. These
findings provide evidence that:
Hawaiian forest food chains exhibit bottom-up structure
Hawaiian forest food chains exhibit both bottom-up and top-down structure
Hawaiian forests are resilient but not necessarily resistant
Hawaiian forests exhibit alternate stable states
Hawaiian forest food chains exhibit top-down structure
In 1970 the deer population of an island forest reserve about 518 square kilometers in size was about 2000 animals. Although the island had excellent vegetation for feeding, the food supply obviously had limits. Thus the forest management personnel feared that overgrazing might lead to mass starvation. Since the area was too remote for hunters, the wildlife service decided to bring in natural predators to control the deer population. It was hoped that natural predation would keep the deer population from becoming too large and also increase the deer quality (or health), as predators often eliminate the weaker members of the herd. In 1971, ten wolves were flown into the island. The data collected during this program are shown in the following table. The Population Change is the number of deer born minus the number of deer that died during that year. Fill in the last column for each year. The first has been calculated for you. Then graph the deer and wolf populations on the graph below.…

- About 25 years ago, the crazy ant (Anoplolepis gracilipes) was introduced to Christmas Island (a 134 km2 island in the Indian Ocean). Despite accounting for less than 2% of the total biomass in the ecosystem, crazy ants drove the native red land crab extinct. The red land crab was the dominant consumer on the forest floor. By eliminating the land crab, crazy ants indirectly release seedling recruitment, enhance species richness of seedlings. In the forest canopy, new associations between this invasive ant and honeydew-secreting scale insects accelerated changes. Sustained high densities of foraging ants on canopy trees result in high population densities of host- generalist scale insects and growth of sooty molds, leading to the death of canopy trees. The total impact (Tli) of the crazy ant is 0.85. Based on this information, you can conclude that the crazy ant is: both a keystone and a dominant species both a keystone and a parasite species a dominant species a keystone species a…arrow_forwardproductivity in above-ground biomass increment is greater in the estuarine stand than the island fringing stand productivity in litterfall is greater in the estuarine stand than the island fringing stand O productivity can be measured in part by measuring carbon in litterfall O productivity can be measured in part by measuring carbon in above-ground biomass increment subtracting above-ground biomass increment from litterfall provides the total productivity for a mangrove standarrow_forwardFigure 5.

- Fox Mountain Lion Snake Hawk Frog Robin Deer Grasshopper Rabbit Caterpillar Grass Tree In this ecosystem, hunting for deer has become a common practice among many residents of nearby communities. If hunting continues and drastically reduces the deer population, how might this impact the hawk population? Hawks do not rely on deer for food, so the hawk population would be unaffected. Having less deer would increase the mountain lion dependency on rabbits, which would lead to fewer rabbits available for the hawks. Having less deer would affect the trees in the ecosystem leading to fewer nesting sites for the hawks. Having less deer would increase the rabbit population providing additional food for the hawks and increase the hawk population.arrow_forwardWhy have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems? 2 of 302 of 30 Questions Listen Question Why have frequent small controlled-burn wildfires not helped to maintain chaparral ecosystems? Seeds of chaparral shrubs need a large accumulation of leaf litter in order to sprout. The heat from forest fires destroys the roots of chaparral plants. Fire destroys the seeds of many types of chaparral shrubs. Burnt ground encourages the growth of grasses, which compete with shrubs for nutrients.arrow_forwardt or f If a pesticide was applied to gourds and started to bioaccumulate in them, biomagnification would result in high concentrations of the pesticide in wild dogs.
