Original ResearchRangeland Responses to Predicted Increases in Drought ExtremityUnder a Creative Commons license Open access On the Ground• Rangeland managers actively focus on the potential to induce a shift in a site to an alternative state, but predicted changes in climate, particularly the likelihood of more extreme drought, necessitate reevaluating risks for alternative states. •Rangelands will differ in their susceptibility to undergo state changes due to climate change in general and for droughts of the future, in particular, which may be hotter. Trees, shrubs, and grasses are expected to differ in their sensitivity to drought, with trees likely being most sensitive; this affects the likelihood for state changes in grasslands, shrublands, woodlands, and savannas. •Considering these differences can help rangeland managers deal with the challenges of increasing drought that is forecast to occur with climate change.

They were introduced into southern Florida in1992. These pythons feed on many of the native Florida species, establishing the pythons as the top predator in theenvironment. By the year 2000, their population had increased dramatically.Figures 1 and 2 display data collected by ecologists studying the results of the Burmese python invasion. Figure 1shows counts of animals collected from nighttime road surveys in southern Florida, which are used to estimatepopulation size. Figure 2 shows data collected from mosquitoes captured from the wild.sequencing was usedto identify the species of blood that the mosquitoes had in their stomachs, identifying various hosts used by themosquitoes.Figure 1.

Researchers counted the numbers of plants species in four different categories at two nearby sites within the savanna rangeland; one lightly grazed by herbivores andone heavily grazed by herbivores(Figure 1).Which of the following best predicts the results of a drought in the savanna research area withregards to community resilience to this environmental change? Get answer to your question and much more 4.The following data was collected from two separate communities of trees: Get answer to your question and much more 5.Students in a class were divided into five groups to analyze community structure. Each group ofstudents assessed the species of plants in four environments and determined the Simpson'sDiversity Index for each environment. The Simpson's Diversity Index takes into account thenumber of species present as well as the abundance of each species. The index values are shown inFigure 1.Based on the data in Figure 1, which of the following statements is most accurate about the speciesdiversity of the four different environments that the students analyzed?

Without natural herbivores or competitors C. texifolia will grow rapidly and crowd out native species of producers. Which of the following best predicts a key difference in prokaryotes and eukaryotes with regard to transcription and translation?Based on the information in Table 1, which of the following best predicts a key difference in prokaryotes and eukaryotes with regard to transcription and translation? The two processes will occur simultaneously in prokaryotes but not eukaryotes. Which of the following best predicts the effects of an increase in killer whale predation on sea otters on the Adak Island ecosystem?Which of the following best predicts the effects of an increase in killer whale predation on sea otters on the Adak Island ecosystem? The sea urchin population will increase and the kelp population will decrease, leading to reduced total biomass and diversity in the Adak Island ecosystem. Which of the following statements best predicts the effect of increased Cottonwood growth on the food web?Which of the following statements best predicts the effect of increased cottonwood growth on the food web? Increased cottonwood growth will provide more resources for cicadas, resulting in an increase in the kestrel population. Which of the following most accurately explains an impact of Burmese pythons on the Everglades community in southern Florida using the data provided quizlet?Which of the following most accurately explains an impact of Burmese pythons on the Everglades community in southern Florida using the data provided? Python predation has caused a trophic cascade that changed the mosquitoes' niche.
