ScLi10- Identify study vаriаbles in reseаrch articles A study tested if acоrn ants that are raised in different temperatures are mоre tоlerant to extreme heat or cold. Here is an excerpt of the methods: "After collection from the field, ant colonies were allowed to acclimate to laboratory conditions (~25 °C, an intermediate temperature between our two temperature treatments) for approximately 24 h prior to being randomly assigned to one of two temperature treatments (Percival growth chambers, 36-VL). We used a simple diurnal fluctuation in temperature for both our warm and cool rearing treatments. The warm treatment cycled between 25 (night) and 30 (day) °C; the cool treatment cycled between 20 (night) and 25 (day) °C. These temperature treatments represent a non-stressful range for this species (Diamond et al., 2013), and correspond with typical warm-day conditions in urban and rural habitats, respectively, in our study area; none of these temperature treatments lie outside the range of temperatures experienced by acorn ants at our study sites (Fig. 1). [...] Photoperiod in each treatment was 14:10 L:D. Colonies were maintained in the temperature treatments for an average of 65.48 days (± 1SD 8.11). [...] We used a dynamic temperature ramping protocol to assess the critical thermal maximum and minimum (CTmax and CTmin), each defined as the loss of muscular coordination, which yields an ecologically relevant tolerance limit (Lutterschmidt & Hutchison, 1997).

ScLi13- Identify elements in results thаt prоvide infоrmаtiоn on how study vаriables behaved The following 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. " Which of the following statements in the results section address the predictions mentioned above?
ScLi15- Determine whether results оf а reseаrch study аnswer the research questiоn The fоllowing is an excerpt of the study Herbivore effects increase with latitude across the extent of a foundational seagrass, whose first author is Dr. Justin Campbell (a professor in our bio department). "In this Article, we used a network of 650 experimental plots distributed across 13 seagrass meadows in the western North Atlantic to explore the effects of increased herbivory on a marine ecosystem under the emerging threat of tropicalization. We were particularly interested in high-latitude turtlegrass meadows at the northern edge of this species’ range, and our approach was a comparative analysis of herbivore effects (and the drivers of its variation) across tropical–subtropical waters. We specifically asked (1) What are the effects of increased herbivory on the health and ecological functioning of turtlegrass across its geographic extent? (2) Are these effects more prominent at the higher latitudes near northern range boundaries? [...] To answer these questions, we conducted a synchronous, year-long manipulative field experiment at turtlegrass sites distributed from Panama (9° N) to Bermuda (32° N) (Fig. 1a). At each site, we factorially manipulated grazing intensity and nutrient availability. Grazing was manipulated using two techniques (1) the exclusion of large natural grazers (turtles and large herbivorous fishes) using mesh caging and (2) the simulation of increased grazing by clipping the leaf canopy to varying degrees, severe grazing (full-clip) and moderate grazing (half -clip) (Fig. 1 and Extended Data Fig. 1). Nutrient availability was manipulated by fertilizer amendments. " based on figure 2, what can researchers conclude? a,b, Effects of simulated grazing across latitude (°N) (a) and light (PAR, µmol photons per m2 per s) (b) after the summer growing season. Jittered points are the raw data and represent individual plots (n = 50 plots per site). Lines represent linear fits with 95% confidence intervals for the severe grazing (red), moderate grazing (blue) and no grazing (black) treatments. Interaction terms were significant for the severe grazing treatments (indicated with an asterisk): latitude × full clip, P = 0.0185 (a); light × full clip, P
