wildlife habitat quiz 3

if a moose selects wetland habitats within its established home range, the behavior is best described as:

3rd order selection

what method of combining variables would most penalize a site that is unsuitable for 1 variable but suitable for another?

geometric mean

what is the role of splitting data into a testing & training dataset in species distribution modeling?

it evaluates how well the model predicts unseen data

a conservation team creates a stage-structured model for a bird and finds that adult survival has a higher elasticity than chick survival, though chick survival is low. What should they prioritize in management?

reducing adult mortality

which model would be best at tracking how changes in adult vs. juvenile survival affect population growth: stage-structured demographic model or a simple logistic growth population model?

stage-structured

why did the Crawford et al. (2020) paper model habitat suitability separately for different ecoregions?

species-habitat relationships varied geographically

in Johnson’s orders of habitat selection, which tree species the fruit dove prefers to forage within is ____ order selection

fourth

in species distribution models, ________ data represent locations where a species is not detected and thought not to occur, but actual absence has not been confirmed

pseudoabsence

elasticity analyses in demographic models help identify which life stages or parameters have the greatest influence on __________ ______

population growth

in a stage-structured diagram, a looped arrow from the adult stage back to itself represents ______

survival

The abundance of newts depends on the presence of vernal pools, amount of forested cover, and proximity to ponds. This is an example of a __________ model

conceptual

the area used by an animal for normal activities like foraging, mating, and shelter

home range

if an animal defends part of its home range from others of the same species, the defended portion is known as its _________

the biggest difference between HSI and niche modeling is that HSI models are based on known life requisites and expert judgement, while niche models are based on _______ patterns

statistical

“lower SI value” approach

overall HSI = lowest SI
