ScLi12- Identify the elements in the methоds thаt аllоw reseаrchers answer their research questiоn A hypothetical study aimed to investigate the factors that affect white-tailed deer (Odocoileus virginianus) abundance in the Northwest US will assess population size in 5 semi-urban environments. Researchers will measure- vegetation density, plant species diversity, age structure of individuals, and presence of predators. They will use capture-recapture methods to estimate population size. They will sex, age and measure all individuals captured. They will divide each area by 10-m-10m transects and sample all plant species found in 30 transects selected randomly. Which of the following statements are correct?
ScLi14- Interpret grаphs, chаrts аnd statistics in results оf research studies A study that wanted tо determine if the persоnality of prey is affected by the type of predator they have did the following: "We first measured how bold or shy mud crabs were based on the amount of time they spent hidden in the presence of predator odors (blue crab, an active predator and toadfish, an ambush predator). We used the same crabs to assess whether crab predation risk was influenced by the proportion of time individual crabs spend in refuge within oyster shells and by predator species. During each trial, a single toadfish, blue crab or no predator (to serve as a control for cannibalism) was placed in each mesocosm (with refuges and mussels) depending on the experimental treatment. Mud crab survival was checked daily for seven consecutive days to determine which individuals were consumed." Figure 3. Histograms of the amount of mud crabs, Panopeus herbstii, consumed by predatory (a) blue crabs Callinectes sapidus, and (b) toadfish Opsanus tau for each behavioural class of mud crab. Crab behaviour was measured as the proportion of observations over 3 h in which a crab was observed taking refuge under oyster shells. The x axis represent the crab personalities: 0 would be a very bold crab (never in refuge) and 1.0 would be a very shy crab (always in refuge) Which statements are true?
