Question 1

Slide 2

Answer 1

Share deciduous and conifer tree habitats and so compete for resources

315 mm more than reds

Forage faster so source food more effectively

Successful beh – guard seeds by storing them in hard to access areas and strip bark of oak and beach trees that make red specific habitats and reduce their availability.

Greys multiple habitat ranges that change seasonally reds struggle to adapt.

Intelligent behaviour – cut red oak radicles before germination

Host squirrel pox and have antibodies and resist symptoms whilst reds die weeks after exposure

Question 2

Answer 2

Scent use – population growth /disease – 2003-2010 reduced population of infectious greys in Europe by 4%

Scent use – future – hazelnut paste override smell of immunocontraceptives so consumed.

-Other notably expressed behaviours - stuck their head into cups - ss/co - 9 times - smelled cups - ss/co - 10 times.

Question 4

Slide 10

Answer 4

Ss – not sig co – study communication through tail movement
Ss – No. Inter beh. – energy expenditure during foraging
Ss – inter beh - Sticking head in cup and Object smelling which has been counted as a sign of significant attraction in other studies.

Pb – not sig co - study testing lure success
Pb – No. Inter beh – food availability and marking them
Pb – inter beh – aforementioned study cup smelling could be significant and bait container biting has been treated a sig attraction, and cup tugging been argued as sign of desire for investigation not attraction.

Question 5

Slide 11

Answer 5

Ro – not sig co – studies conducted before the year 2000 and other studies found better for luring other rodents e.g cotton mice
Ro – no. inter beh – studies outdated and had to mix them with other attractants.
