Biodiversity Hotspots Quiz

Question 1An illustrative region originally had 64000 km² of natural vegetation and retains 17920 km². Find the percentage remaining, rounded to one decimal place.

Enter a number in %.

Answers within 0.05 % of the expected value are accepted.

Question 2Within a region, an inventory lists 2250 native plant species, including 720 endemic species. Find the endemic share in percent, rounded to one decimal place.

Enter a number in %.

Answers within 0.05 % of the expected value are accepted.

Question 3Which pair of thresholds defines a terrestrial biodiversity hotspot?

At least 1,500 endemic vascular plants and at least 70% of original vegetation retainedAt least 1,500 visiting bird species and at least 70% of original vegetation lostAt least 1,500 endemic vascular plants and at least 70% of original vegetation lostAt least 1,500 protected hectares and at least 70% of original vegetation retained

Question 4A forest contains many widespread species, while another has fewer species confined to that region. What does the second forest add that total richness misses?

A greater concentration of biological uniquenessA larger share of species found across several continentsA higher total number of speciesMore vegetation covering a greater land area

Question 5Analysts combine field records with habitat imagery to draw a hotspot boundary. Which task improves the range evidence?

Place the boundary around the largest administrative districtUse the illustration’s colors to decide which plants share an identityRank reports by file size before assigning species rangesCheck record locations and reconcile species identifications

Question 6Populations on isolated mountain slopes diverge while dispersal stays limited. What geographic mechanism is involved?

A barrier to migration that allows separate lineages to developA rise in area that makes the slopes geographically identicalA change in map scale creating new organismsA legal boundary changing the inherited traits directly

Question 7A developer says a hotspot label itself is a zoning prohibition. Which correction applies?

A global inventory grants the developer ownership of the siteThe label replaces the need for a permit authorityThe designation transfers municipal powers to map publishersBinding restrictions come from applicable law and site rules

Question 8Within a hotspot, planners compare a remnant forest corridor with an industrial field. How should they choose a conservation action?

Choose the field because cleared land has greater ecological continuityAllocate identical management because both lie inside the lineAssess the functions and vulnerable populations at each siteReplace surveys with the regional designation’s publication date

Question 9An extensive intact wilderness fails the habitat-loss threshold. What follows for conservation planning?

Its ecological value is lower than that of a paved hotspot parcelOther priorities still justify assessing its protection needsIt must be cleared further before preventive action is usefulIt has no role in a plan addressing migration or freshwater

Question 10A damaged region is replanted after a narrow-range species has become extinct. What is a sound expectation?

Planting records establish that the extinct population has recoveredNew habitat develops, but the lost species is not recreatedThe original community returns as soon as the trees are plantedA matching tree count reproduces the former soil relationships
