Evidence of re-nesting after brood loss in Red Grouse Lagopus lagopus scoticus

Willow Ptarmigan (Lagopus lagopus) Science Article 9 abstract The Red Grouse Lagopus lagopus scoticus is a single-brooded species that can re-lay if a clutch is lost during the nesting period (Cramp & Simmons 1980). However, there is no reported evidence regarding second clutches being attempted after a brood of young chicks is lost. Indeed, there […]

Territorial behaviour and population dynamics in red grouse Lagopus lagopus scoticus. II. Population models

Willow Ptarmigan (Lagopus lagopus) Science Article 1 abstract 1) Recent experiments on cyclic red grouse populations discovered that aggressiveness, induced by testosterone implants, depressed population density for more than a year after the implants were exhausted. 2) This confirms the observation, also made in previous studies of this territorial species, that aggressiveness can determine population […]

Can parasites synchronise the population fluctuations of sympatrictetraonids? / examining some minimum conditions

Willow Ptarmigan (Lagopus lagopus) Science Article 12 abstract Sympatric populations of tetraonid birds tend to fluctuate in synchrony, at least onlocal scales. If shared parasites among sympatric populations of different tetraonidspecies are to operate as a local, synchronizing factor for population fluctuations atleast two conditions should be met Per R.
