Abstract This study investigates social monogamy in the Australian sleepy lizard, Tiliqua rugosa. At a 70-ha site near Mount Mary, South Australia, we radio tracked 55 adult female and 39 adult male lizards during their spring activity periods. Each lizard was observed in 1–5 years. Females were observed with a single male partner on an average of 10.8 days per year, although in 17.3% of cases, females were observed on 2 or fewer days with a male. The most intense pairing period each year was… 
Following trails of partners in the monogamous lizard, Tiliqua rugosa
TLDR
There is trail following, at least by females, and that females play an active role in maintaining the partnership, which refutes male-based explanations, like mate guarding, for monogamy.

High levels of genetic monogamy in the group‐living Australian lizard Egernia stokesii
TLDR
The results suggest that monogamy both within and between seasons is a common mating strategy of E. stokesii and that breeding partners maintain stable associations together and with multiple cohorts of their offspring over periods of up to at least 5 years.
Aggressiveness during monogamous pairing in the sleepy lizard, Tiliqua rugosa: a test of the mate guarding hypothesis
TLDR
It is suggested that monogamy may be maintained through some form of female coercion, allowing females to gain additional fitness from the enhanced vigilance that results from male proximity.
Reunion vigour: an experimental test of the mate guarding hypothesis in the monogamous sleepy lizard (Tiliqua rugosa)
TLDR
Results are consistent with predictions that the monogamous relationship in the sleepy lizard is a form of mate guarding by males, but the incidence of females re-uniting with males, and the long duration of pair bonds before mating occurs are not predicted by a mate guarding hypothesis.
Monogamy in an Australian arboreal marsupial, the yellow-bellied glider (Petaurus australis)
TLDR
It is suggested that social and genetic monogamy predominated in this population of yellow-bellied gliders in south-western Victoria, demonstrated by extensive home-range overlap between cohabiting adult males and females and little home- range overlap between adjacent territories.
Multiple paternity in a salamander with socially monogamous behaviour
TLDR
Paternity in clutches of red‐backed salamanders (Plethodon cinereus), a species in which social monogamy has been demonstrated in the laboratory, and 28% of individuals in the forest are found in male‐female pairs in the noncourtship season is analysed, concludes that, at least in this population, social monogaming is not concomitant with genetic monogamy.
Size-Assortative Pairing and Social Monogamy in a Neotropical Lizard, Anolis limifrons (Squamata: Polychrotidae)
TLDR
Although social monogamy has not been widely reported in squamates, it is suggested that more examples of this phenomenon will be described as the social behaviors of poorly known species are increasingly subject to study.
Relatedness and avoidance of inbreeding in the lizard, Tiliqua rugosa
TLDR
Females were as closely related to other females as they were to males, both within the whole study area, and within home ranges, which suggests that dispersal in the population is not sex-biased.
Home Ranges and Reproductive Strategies in a Neotropical Lizard, Liolaemus quilmes (Iguania: Liolaemidae)
TLDR
Female home ranges, on the other hand, remained stable throughout the study except for a tendency to be larger during the post-reproductive than during the reproductive season, which suggests that food availability during their post-oviposition recovery period could be more important than number of males.

Asynchronous Seasonal Activity of Male and Female Sleepy Lizards, Tiliqua rugosa
An eight-year survey of a population of the sleepy lizard, Tiliqua rugosa, near Mt. Mary in South Australia, resulted in 10,771 random encounters of active adult lizards. Among this sample there was
Enhanced vigilance in monogamous pairs of the lizard, Tiliqua rugosa
The Australian sleepy lizard, Tiliqua rugosa, forms monogamous pairs for up to 8 weeks each spring before r"=»ring We observed that males had food in their mouths significantly less often when they
Sexually dimorphic head sizes and reproductive success in the sleepy lizard Tiliqua rugosa
TLDR
In 1993, 458 males and 346 females of the largve Australian skink, Tiliqua rugosa, were captured in a study area near Mt. Mary, South Australia and the hypothesis that head size is under sexual selection was supported.
Comparisons of Displaced and Retained Partners in a Monogamous Lizard
TLDR
A population of the skink Trachydosaurus rugosus from near Mt Mary, South Australia, was studied over 7 years and found that lizards that were displaced were as likely as retained partners to survive, as measured by recaptures in subsequent years.
A Population Study of the Viviparous Australian Lizard, Trachydosaurus rugosus (Scincidae)
TLDR
Growth rate data from recaptured individuals indicated that a lizard can reach maturity by its third spring season at an approximate age of 30 mo, and longevity could not be assessed, but many lizards were at least 9 yr old by the end of the study.
Population ecology of the sleepy lizard, Tiliqua rugosa, at Mt Mary, South Australia
TLDR
A population of the sleepy lizard, Tiliqua rugosa, near Mt Mary, South Australia, was surveyed by random encounter captures along 42 km of transects over a 10 year period from 1982 to 1991, which revealed a population structure governed by low recruitment, but long survival of established adults.
Home range overlap of mothers and their offspring in the sleepy lizard, Tiliqua rugosa
TLDR
A field investigation of interactions between juveniles and their mothers in the Australian sleepy lizard, Tiliqua rugosa, finds the extended tolerance of home range overlap represents a greater degree of mother-offspring association than has been previously reported for other lizards.
Characterization of microsatellite loci from the socially monogamous lizard Tiliqua rugosa using a PCR‐based isolation technique
TLDR
The characterization of polymorphic microsatellite loci from Tiliqua rugosa are reported and their potential use for testing whether T. rugosa is sexually monogamous is discussed.
Maximizing male reproductive success in the broad-headed skink (Eumeces laticeps): preliminary evidence for mate guarding, size-assortative pairing, and opportunistic extra-pair mating
Several lines of evidence suggest that male Eumeces laticeps may increase reproductive success by 1) mating with larger females to increase clutch size, 2) mate guarding to be present during the
Sperm competition in the sand lizard, Lacerta agilis
TLDR
Sperm did not survive in the female reproductive tract between ovulations, and sterilized males did not lower the probability of paternity for males in a second copulation occurring within 24 h, suggesting that neither mating order nor time between copulations has any impact on the reproductive success of first or last males.
