Over 100 courtship encounters involving 32 Blanding's turtles, Emydoidea blan- dingi, were observed under seminatural conditions and the data were analyzed by cinemato- graphic techniques. Eight mutually exclusive motor patterns are described for males. A definite sequence is necessary in order for mating to occur. Following initial chasing and mounting, the male exhibits a series of tactile, visual and (possibly) olfactory displays that lead either to ter- mination of the sequence by the… 
An analysis of courtship behaviour in the four-eyed spotted turtle, Sacalia quadriocellata (Reptilia: Testudines: Geoemydidae)
TLDR
A total of 168 courtship sequences from 12 male and 18 female adult captive Sacalia quadriocellata were recorded on video and the behavioural sequences were summarized in an intra-individual dyadic transition matrix and analyzed using chi-square and kappa analyses.
03. Quantitative analysis of courtship and mating behaviours in the big-headed turtle, Platysternon megacephalum
TLDR
This study provides the first record of male biting during courtship behaviour in an Asian turtle species, and recommendations for captive breeding of the endangered species P. megacephalum are presented.
An overview of same-sex mounting in turtles and tortoises
TLDR
Compilation of the data revealed that in almost every species with reports of same-sex mounting there were dominance relationships mediated by aggressive/submissive interactions; most of these cases occurred in captivity, and the sex ratios were not skewed.
Sex in the Half-Shell: A Review of the Functions and Evolution of Courtship Behavior in Freshwater Turtles
TLDR
The evolution of courtship behavior in freshwater turtles might accompany the evolution of sexual dimorphism, which is directly subject to natural selection.
Analysis of courtship behaviors of the desert tortoise, Gopherus agassizii
TLDR
Male courtship behavior changed with increased courtship experience, and smaller males showed more variable behavior than larger males, which lends insight into the sources and amount of variability in reptilian reproductive behaviors.
High Frequency of Multiple Paternity in Blanding's Turtle (Emys blandingii)
TLDR
The high frequency of multiple paternity observed here suggests that multiple mating may be beneficial to females and/or their offspring and further research is needed to determine whether this is the case and, if so, how females may benefit from multiple matings.
Courtship Behavior of the Cumberland Plateau Woodland Salamander, Plethodon kentucki (Amphibia: Plethodontidae), with a Review of Courtship in the Genus Plethodon
TLDR
This work investigated the courtship behavior of the Cumberland Plateau woodland salamander (Plethodon kentucki) and compared it to previous accounts of courtship in other Plethodon species, and constructed a flow diagram of significant motor-pattern transitions during courtship.
HOW, WHEN, AND WHERE TO PERFORM VISUAL DISPLAYS: THE CASE OF THE AMAZONIAN FROG HYLA PARVICEPS
TLDR
It is suggested that the simultaneous production of auditory and visual signals may momentarily increase a sender's locatability when a conspecific receiver is detected.
Assessing Head Morphology Dimorphism in the Midland Painted Turtle (Chrysemys picta marginata) Using a Photographic Questionnaire
TLDR
This study is among the first to describe, assess, and discuss the functional significance of head dimorphism in this model species, and suggests that visual questionnaires are a quantifiable method of assessing dimorphic characters that can be used in addition to traditional morphometrics or geometric Morphometrics to demonstrate a visual, rather than simply statistical, difference among characters and sexes.
Spectral Reflectance of Blanding’s Turtle (Emydoidea blandingii) and Substrate Color-Induced Melanization in Laboratory-reared Turtles
TLDR
The authors' data, and comparisons with other studies, indicated that different physiological control systems of the melanization process appear to exist among species and among tissue regions within individuals.

Display Behavior in Tortoises
When compared to lizards or snakes, signals related to warning and threat are not very important in land tortoises. Within social and sexual contexts, tactile and chemical signals seem more important
Observations on the ecology and population dynamics of the Blanding's turtle, Emydoidea blandingi
TLDR
Ecological studies were made on the Blanding's turtle in southwestern Michigan regarding population size and structure, seasonal activity, and reproductive potential and cycles.
Observations on behavior and ecology in an Australian turtle, Chelodina expansa (Testudines: Chelidae)
TLDR
Observations of natural populations and captives over a period of 6 years provide preliminary information on the ecology of a poorly known and secretive species and head bobbing and self-grooming behavior are described.
VARIATION, SEXUAL DIMORPHISM, AND MATURITY IN A QUEBEC POPULATION OF THE COMMON SNAPPING TURTLE, CHELYDRA SERPENTINA
TLDR
The sex ratio is one, males grow to a larger size than females, and the ratio precloacal distance over posterior lobe of the plastron gives a practical index for sex determination in adults.
