10 practice questions, worked

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.

1 · Herpetology: reptiles and amphibians · medium

Legless, burrowing amphibians belong to the order:

  1. Gymnophiona
  2. Anura
  3. Caudata
  4. Squamata
Answer and working

A. Gymnophiona

Caecilians form the order Gymnophiona.

2 · Herpetology: reptiles and amphibians · medium

Chytridiomycosis, which has caused amphibian declines worldwide, is caused by:

  1. A virus
  2. A bacterium
  3. A nematode
  4. A fungus
Answer and working

D. A fungus

Batrachochytrium dendrobatidis.

3 · Herpetology: reptiles and amphibians · medium

The purple frog, which spends most of its life underground, is endemic to the:

  1. Thar desert
  2. Andaman Islands
  3. Western Ghats
  4. Trans-Himalaya
Answer and working

C. Western Ghats

Nasikabatrachus sahyadrensis.

4 · Habitat: food, water, cover and space · hard

Resource selection functions estimate habitat preference by comparing:

  1. Used with available habitat
  2. Births with deaths each year
  3. Males with females in a herd
  4. Tracks with pellet groups
Answer and working

A. Used with available habitat

Use relative to availability.

5 · Animal behaviour relevant to management · medium

The marginal value theorem predicts:

  1. When a forager should leave a patch
  2. How many young a female should rear
  3. When a population reaches K
  4. How far seeds are dispersed
Answer and working

A. When a forager should leave a patch

Charnov's optimal patch-leaving rule.

6 · Animal behaviour relevant to management · medium

Imprinting, important in captive rearing for reintroduction, was described in geese by:

  1. Aldo Leopold
  2. Konrad Lorenz
  3. Salim Ali
  4. Charles Elton
Answer and working

B. Konrad Lorenz

Lorenz's work on imprinting.

7 · Population dynamics: natality, mortality, carrying capacity · medium

Large, long-lived species with low reproductive rates are described as:

  1. r-selected
  2. Semelparous
  3. K-selected
  4. Ectothermic
Answer and working

C. K-selected

MacArthur and Wilson's K-selection.

8 · Mark-recapture estimation · medium

Which is an assumption of the Lincoln-Petersen estimator?

  1. Marked animals become easier to catch
  2. Births balance deaths between samples
  3. The population is closed between samples
  4. Capture probability rises with age
Answer and working

C. The population is closed between samples

Closure, equal catchability, harmless marks, no mark loss.

9 · Mark-recapture estimation · medium

Heterogeneity in capture probability among individuals usually causes the population to be:

  1. Overestimated
  2. Estimated exactly
  3. Underestimated
  4. Counted twice
Answer and working

C. Underestimated

Hard-to-catch animals are missed.

10 · Biodiversity monitoring and occupancy surveys · medium

Detecting species from traces of DNA in water or soil is called:

  1. Radio telemetry
  2. Environmental DNA
  3. Pellet counting
  4. Distance sampling
Answer and working

B. Environmental DNA

Environmental DNA (eDNA) detects species from traces.
