ScLi14- Interpret grаphs, chаrts аnd statistics in results оf research studies A study wanted tо determine the relatiоnship between two species of ant (P. ferrugineus and P gracilis) and an acacia tree. Both species of ants take nectar from the tree. One hypothesis is that in return, ants protect the trees by killing bacteria that can infect acacias. This are their results: What did researchers show?
ScLi6- Identify reseаrch questiоns/gаps аddressed by research papers The fоllоwing paragraph describes a study about the introduction of the Burmese python in the Everglades. "The Burmese python, Python bivittatus Kuhl, is an invasive apex predator that has established in southern Florida and has been incriminated in large-scale mammal declines. We investigated whether the python-attributed impacts on the mammal community of southern Florida have impacted contact between the hosts and vectors of the Everglades virus (EVEV, a mosquito-borne Alphavirus endemic to Florida). The hispid cotton rat, Sigmodon hispidus, and the cotton mouse, Peromyscus gossypinus, are reservoir hosts of EVEV and the mosquito Culex cedecei is the sole vector. Field studies from southern Florida during the late 1970s demonstrated that Cx. cedecei feeds predominantly (88–90%) upon mammals, acquiring about half of blood meals from rodents in the Everglades, the remainder (46%) being derived from medium-sized (northern raccoon, Procyon lotor (Linnaeus), Virginia opossum, Didelphis virginiana Kerr) and large-sized mammals (white-tailed deer, Odocoileus virginianus (Zimmermann)). During the 1970s and thereafter, these medium- and large-sized mammals were common in the Everglades National Park. However, by the early 2000s, raccoon, opossum and deer experienced massive declines (87.5–99.3% reductions) in the Everglades National Park linked to the proliferation of the Burmese python, while rodent populations have remained stable or even slightly increased. These changes in host abundance may have profound effects on host use, given dramatic differences in size (deer versus rat) and circadian patterns of activity of the hosts as well as vectors, resulting in unequal exposure to bites. Comparing host use of the EVEV vector Cx. cedecei prior to python invasion with current host use patterns provides the opportunity to investigate how an invasive apex predator may alter host–vector contact, a key interaction driving pathogen transmission. " Based on this paragraph, what is the gap that the paper is addressing?
