When two spiny mouse species coexist, Acomys cahirinus is nocturnal, whereas A. russatus is active during the day. When all A. cahirinus were removed from a research site, diurnal A. russatus mice became nocturnal. How were resources partitioned between these species when they coexisted, and what do these results indicate about the niche of A. russatus?

When two spiny mouse species coexist, Acomys cahirinus is nocturnal, whereas A. russatus is active during the day. When all A. cahirinus were removed from a research site, diurnal A. russatus mice became nocturnal. How were resources partitioned between these species when they coexisted, and what do these results indicate about the niche of A. russatus?

Expert Solution & Answer

Summary Introduction

To determine: The way in which resources are partitioned between the co-existed species, Acomys cahirinus and Acomys russatus. Also, determine the nature of the niche of Acomys russatus.

Introduction: The two species of Acomys, namely Acomys cahirinus and Acomys russatus, are co-existed species. Acomys cahirinus is a nocturnal species whereas Acomys russatus is a diurnal species.

Explanation of Solution

In this case, when all the Acomys cahirinus were removed from a particular site of research, all the species of Acomys russatus became nocturnal. It describes the concept of displacement of characters where the sympatric type of species diverge more than the allopatric ones.

When these species co-exist, they must differentiate their ecological niches to guard against dying out.

Also, Acomys russatus possesses a higher potential niche than its actual niche. It occurs because this species also exist at night, but this species has somehow adjusted their niche to survive in the surrounding environment.

Conclusion

Thus, both the species differentiate their resources to co-exist in a better way. Also, Acomys russatus adjusted its particular niche for its survival in the living environment.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
