Reproductive behavior of Spix’s Whiptails in the wild: understanding the costs and benefits of mate-guarding
By accepting mate-guarding, females do not appear to have energetic gains and lose the advantage of cryptic mate choice but can benefit from access to high-quality males and protection from harassment.
Effects of male size and mate quality on male-male contest in the hermit crab Pagurus filholi
Results suggest that a male P. filholi can assess the quality of female it is guarding and remember its assessment for at least a short period of time, and asymmetry between contestants in this memory store for female quality could affect the process and the outcome of male-male contests in P. Filholi.
Mate-guarding constrains feeding activity but not energetic status of wild male long-tailed macaques (Macaca fascicularis)
It is hypothesized that the energetic costs of mate-guarding vary inter-specifically depending on the degree of seasonality and that males of non-strictly seasonal species might be better adapted to maintain balanced energetic condition year-round.
Lack of Evidence for Energetic Costs of Mate-Guarding in Wild Male Assamese Macaques (Macaca assamensis)
The results do not support the idea that seasonally breeding males in marginal habitats face energetic costs of mate-guarding, and it is suggested that though these costs may be found in species where strength, size, and mass predict rank, mating, and reproductive success, males may not engage in costly mate-GUarding in species such as Assamese macaques.
Male mate choice as differential investment in contest competition is affected by female ornament expression
It is suggested that males adjust their energetic investment during intrasexual competitive interactions in response to variation in the contested female which, assuming males gain direct or indirect benefits from their strategic allocation of reproductive effort, fits the modern understanding of male mate choice.

An Essential Role of the Arginine Vasotocin System in Mate-Guarding Behaviors in Triadic Relationships of Medaka Fish (Oryzias latipes)
It is shown that male medaka fish prominently exhibit mate-guarding behavior and that there are redundant systems to activate V1a2 and that endogenous ligands activating the receptor may differ according to the social context.
Mate guarding and frequent copulation in birds: A meta‐analysis of their relationship to paternity and male phenotype
A significant positive correlation between both presumed paternity protection behaviors and paternity share is found, however, the relationship is weak and a negative correlation between male quality and paternity protection is found.


Increased predation risk while mate guarding as a cost of reproduction for male broad-headed skinks (Eumeces laticeps)
Studying potential antipredatory costs of mate guarding by simulating predators searching for and approaching pairs of lizards in the field found males frequently followed females by scanning visually and scent trailing, exposing themselves to the predator while the female hid.
The effectiveness of mate guarding by male black-throated blue warblers
Examination of mate guarding by male black-throated blue warblers showed that males that guarded their mates more closely were less likely to have extrapair young in their nests, and the experimental detention of a male for 1 h during the fertility risk period increased the probability that a brood would contain extrapairYoung.
Tradeoffs between courtship, fighting, and antipredatory behavior by a lizard, Eumeces laticeps

This study indicates that animals balance increased risk of predation with the opportunity to perform several reproductively important behaviors, and suggests that increasing risk was accepted when reproductive benefits were greater.
Female accompaniment by male whiptail lizards: is it mate guarding?
Analysis of potential functions of post-copulatory accompaniment in whiptail lizards, Aspidoscelis costata, finds that males likely copulate repeatedly, inseminate females more and monopolise access to fertile females, whereas females may receive (1) post-Copulatory courtship, (2) copulations with high quality males and (3) sufficient sperm for fertilisation.

It is demonstrated that mate guarding in the 1st-ranking male is a high-cost mating tactic, while opportunistic mating in subordinate males is a low- cost mating tactic.
Mate guarding, competition and variation in size in male orb-web spiders, Metellina segmentata: a field experiment
The results show that large males have a clear advantage in monopolizing females in the common orb-web spider Metellina segmentata and the manner in which selection acts to maintain large male size in this spider is discussed.
The Interaction of Female Condition and Mating Status on Male-Male Aggression in a Wolf Spider
It is suggested that diet history and body condition mitigate the reproductive advantages of mating with virgin females as indicated by levels of male-male aggression, but further investigation is needed.
Mate guarding and territorial aggression vary with breeding synchrony in golden whistlers (Pachycephala pectoralis)
Evidence is provided that males may be able to detect variation in breeding synchrony and cuckoldry risk and adjust their paternity assurance behaviour accordingly, and this study provides evidence of such sex-specific differences in the golden whistler.
Physiological Costs of Mate Guarding in the Japanese Beetle (Popillia japonica Newman)
Costs of mate guarding in Japanese beetles, a pest species which exhibits post-copulatory mate guarding during which the guarding male cannot feed, are examined to suggest that because guarding males are unable to feed, they suffer energetic and thermoregulatory costs that appear to limit the time that they can guard a female.
Mate guarding in the Seychelles warbler is energetically costly and adjusted to paternity risk

Experimental evidence is provided that mate–guarding behaviour is energetically costly and that the expression of this trade–off is adjusted to paternity risk (local male density).
