Abstract. The territory establishment of male marine iguanas and their subsequent mating success were analysed to identify spatial spillover (hotshot) and temporal spillover effects on lek formation. Males started to establish small display territories 2 months ahead of the mating season. Males did not establish territories in temporal synchrony and did not settle at sites where the probability of encountering females was highest. However, males arriving later preferentially established their…

Male territoriality and mating system in the European beewolf Philanthus triangulum F. (Hymenoptera: Crabronidae): evidence for a “hotspot” lek polygyny
TLDR
It is concluded that the European beewolf exhibits a hotspot lek polygyny with female nesting sites constituting “hotspots” for lek formation.
Large Male Advantage: Phenotypic and Genetic Correlates of Territoriality in Tuatara
TLDR
An assessment of the social structure and factors affecting male territory quality and aggressive behavior in a dense population of Tuatara, a long-lived reptile that maintains long-term territories, on Stephens Island, New Zealand finds the finding of no relationship between territoriality and heterozygosity probably reflects the genetic background of this large, outbred population.
Determinants of yearling male lekking effort and mating success in black grouse (Tetrao tetrix)
TLDR
The results show that yearling male black grouse in good condition can establish territories and have some limited mating success, especially during increasing population density, and, as the results also demonstrate, on extrinsic factors such as population density.
Aggressive Transition between Alternative Male Social Tactics in a Long-Lived Australian Dragon (Physignathus lesueurii) Living at High Density
TLDR
The high level of social plasticity in this population where same-sex competitors are densely concentrated in preferred habitat suggests that chronic high energetic costs of defense may select for males to cycle between territorial and non-territorial social tactics depending upon their changing energetic status and their current capacity for competition with rivals.
Prevalence of Aggression as it Relates to Territory Size, Fish Density, and Neighbor Number in the Yellowtail Damselfish, Stegastes arcifrons
  • Reid W. Collis

Territoriality plays a key role in the survival and reproduction of many species. Damselfish (Family: Pomacentridae), reef-dwelling fish found in tropical locations, are territorial and…
The role of landmarks in territory maintenance by the black saddlebags dragonfly, Tramea lacerata
TLDR
It is hypothesized that in this species, landmarks may only reduce costs during territory establishment, rather than during territory maintenance, and thus may be more important in increasing benefits rather than decreasing the costs of territoriality.
Sex, drugs and mating role: testosterone-induced phenotype-switching in Galapagos marine iguanas
TLDR
It is hypothesized that T levels of males that are based on early-season behavioral interactions influence a males' subsequent phenotypic role, and supports previous data that females may gauge male attractiveness by using head-bob patrolling, here shown to be a T-dependent trait.
Diversity of compounds in femoral secretions of Galápagos iguanas (genera: Amblyrhynchus and Conolophus), and their potential role in sexual communication in lek-mating marine iguanas (Amblyrhynchus cristatus)
TLDR
The diversity of the lipophilic fraction of males’ femoral gland secretions among 11 island populations of marine iguanas is described and the results indicated that 11-eicosenoic acid may play an important role in intraspecific chemical communication in marine iguanaas.
Subordinate superb fairy-wrens (Malurus cyaneus) parasitize the reproductive success of attractive dominant males

  • 2003
TLDR
Microsatellite genotyping is used to assess the extra–group reproductive success of subordinate superb fairy–wrens (Malurus cyaneus), a species with extremely high rates of extra-group paternity and evidence suggests that mate choice in superb Fairy–Wrens is error–prone and subordinates can gain direct reproductive benefits through parasitizing the reproductive successof attractive dominants.
Lek Territory Size and the Evolution of Leks: A Model and a Test Using an Ungulate With a Flexible Mating System

TLDR
It is suggested that much of the variation in the size of lek-territories can be explained by the competition that arises from a female bias for mating on central territories and that is intensified by the number of territorial males in an aggregation.

TLDR
Lekking in marine iguanas may represent a ‘hotshot’ phenomenon where small territorial males associate with large males to increase reproductive success.

Establishment of breeding territory by the chaffinch Fringilla coelebs, and the brambling, F. montifringilla, in northern Finland
TLDR
The establishment of breeding territory by the chaffinch and the brambling was studied at Utajarvi in Finland in the springs of 1967-1972 and suggests that their reproductive tactics diverge.

TLDR
A shift of females from one territory to another within one colony between two succeeding years was correlated with the change in relative weight of territory owners, interpreted as an indication of female choice.
The mating systems of pinnipeds and marine iguanas : convergent evolution of polygyny
TLDR
It is hypothesize that marginal males, through continuous sexual harassment of females that stay outside territories, have exerted pressure towards the evolution of female gregariousness.

Sexual selection in a monomorphic lek-breeding bird: correlates of male mating success in the great snipe Gallinago media
TLDR
It is suggested that male great snipe are subject to sexual selection mainly in behavioural and vocal cues and that this may explain the absence of size and plumage dimorphism in this species.
Cooperation Under Sexual Selection: Age-Graded Changes in a Lekking Bird
TLDR
The results are consistent with the hypothesis that subdefinitive plumages in this species serve primarily as accurate indicators of age, which in turn largely determines status, and that males queue for positions in an age-based dominance system.
Lekking in the black grouse— a test of male viability
TLDR
It is reported here that by choosing victorious males, females mate with males that are most likely to survive the following six months, which supports a basic assumption of the 'good gene' models.
