ScLi9- Identify type оf reseаrch in reseаrch аrticles The fоllоwing is an excerpt of the study The Diversity of Sulfide Oxidation and Sulfate Reduction Genes Expressed by the Bacterial Communities of the Cariaco Basin, Venezuela performed by Dr. Maria Jose Rodriguez Mora, professor in our bio department. "The Cariaco Basin, off the coast of Venezuela, is the largest truly marine permanently anoxic basin in the world. [...] [...]a localized sulfur cycle has been postulated for the redoxcline/anoxic zones of the Cariaco Basin [...]: a portion of the carbon fixed by chemoautotrophic microorganisms could be oxidized by sulfate-reducing microorganisms [...] The dissimilatory sulfite reductase, encoded by the dsrAB genes [13], is ubiquitous to all known sulfate-reducing prokaryotes. [...] The diversity of either sqr or dsrA has not yet been studied in the Cariaco Basin. [...] Therefore, in order to build a cloning library for both DNA and mRNA of the sqr and dsrAB genes, a novel sampling devise “Deep-SID” was used and, as a result, the diversity and expression of the two sulfur metabolism genes in the Cariaco Basin redox transition zone were ascertained. [...] Bacterioplankton samples were collected during the Car153 cruise on January 13th 2009 at station A (10.30°N, 64.40°W), [...] situated in the eastern sub-basin, with a depth of 1400 m. [...] The dsrA gene from sulfate-reducing microorganisms was amplified using primers designed to target conserved regions of the gene, based on multiple alignments of cultured and environmental SRB sequences retrieved from GenBank. dsrA1FM [...] To perform phylogenetic analyses of the cloned genes, alignments were built that included sequences of respective genes from several representatives of known cultured bacteria as well as sequences from the closest cultured and non-cultured relatives identified by BLASTn. [...] What type of study is this?

ScLi15- Determine whether results оf а reseаrch study аnswer the research questiоn The fоllowing excerpt belongs to the study Anthropogenic Marsh Impoundments Alter Collective Tendency in Schooling Fish coauthored by Dr. Kevin Boswell (professor in our bio department). "The objective of this study was to determine whether the collective tendency of schooling fish is modulated by anthropogenically introduced habitat complexity, prior to and in response to predator attack. To achieve this objective, we compared collective state of fish schools before and during predator attack, between an open salt marsh canal and a Water Control Structure (man-made). In those environments, we observed schools of free-ranging juvenile gulf menhaden (Brevoortia patronus) [...]The collective behavioural state of each fish school was quantified using six behavioural parameters [...]: school area, group speed, angular velocity, orientational alignment (polarization), coherence of rotation (rotational order) (Attanasi et al. 2014), and correlation strength (degree of influence on neighbours) (Cavagna et al. 2008; Handegard et al. 2012). [...] we predict that fish schools in the vicinity of a WCS will adjust their schooling tendencies and form less aligned shoals, exhibiting increases in area and decreases in polarization compared to the natural marsh environment. " This is figure 2 Mean comparisons of six behavioural metrics that describe schooling tendency between habitat context and predator attack. Raw metric data is shown behind the mean. Habitat context comparisons, separated on the bottom axis, are separated between pre- and mid-predator attack (separated by colour), presenting comparisons between and within habitat context. Significant differences at 95% confidence level are denoted with an asterisk. Comparisons that do not meet the traditional level of significance but are nearly significant are shown without the asterisk What can researchers conclude?
