Male Columbian ground squirrels, Spermophilus columbianus, give a repetitive vocalization after copulation. This ‘mating call’ sounds similar to certain alarm calls that are given during attacks by terrestrial predators. During 2005–2006, we investigated (1) the acoustic structure and similarity of mating calls and alarm calls; (2) the environmental context when mating calls occur; (3) whether males that are likely to benefit from mate guarding (viz., males that have sperm precedence because… Expand
Why do female Columbian ground squirrels (Spermophilus columbianus) give an estrus call
TLDR
Female Columbian ground squirrels sometimes emit a repetitive vocalization after copulation to encourage sperm competition through mating with additional males and to increase mate guarding by the consort male as a mechanism of postcopulatory female mate choice. Expand
Premating behavioral tactics of Columbian ground squirrels
TLDR
The results supported the hypothesis that entrance into NUCs with a female before she exhibits estrus was a premating tactic that increased male reproductive success when exhibited in concert with other mating tactics such as territorial defense. Expand
Male reproductive tactics to increase paternity in the polygynandrous Columbian ground squirrel (Urocitellus columbianus)
TLDR
The results suggest that besides being the first male to consort, first-male sperm precedence is further enhanced through longer mating bouts and by suppressing the chances and/or efforts of later mating males. Expand
Mating order and reproductive success in male Columbian ground squirrels (Urocitellus columbianus)
TLDR
It is concluded that males gain the largest part of their seasonal reproductive output from mating first with a female due to a pronounced first male advantage but gain considerable additional fitness from mating with additional, already mated females. Expand
Comparing functions of copulation calls in wild olive baboons, Papio anubis, using multimodel inference
TLDR
The possibility that copulation calls have no function, functions not included in the analysis, or that they are multifunctional, a reflection of the species' social evolution history is discussed. Expand
Scream of Death: Responses of Female Columbian Ground Squirrels to Anti-Infanticide Pup Distress Calls
TLDR
Female Columbian ground squirrels respond to distress calls based on a location-based rule or vocal recognition per se rather than true vocal recognition, which seems appropriate, since lactating females are territorial and pups rarely mix between litters during the 1–5 day period just after emergence from their natal burrow when they are susceptible to infanticide.

Mating Behavior of Columbian Ground Squirrels
TLDR
Evaluating influences on the territorial behavior of male Columbian ground squirrels in Southwestern Alberta, Canada found that females mated first with a dominant male on whose territory they resided, but mating pairs were not exclusive as females usually mated with additional males. Expand
Why are Male Columbian Ground Squirrels Territorial
TLDR
Male territorial defence is a component of many vertebrate mating systems and is often regarded as a tactic for acquiring mates, and territory ownership serves to facilitate a first mating with females that live on the territory. Expand
Variation in reproductive success of male and female Columbian ground squirrels (Urocitellus columbianus)
TLDR
Investigation of variation in reproductive success of Columbian ground squirrels investigated whether male reproductive success was more variable than that of females under this mating system, and found that males were about three times as variable in reproductiv... Expand
Male mate guarding in a socially monogamous mammal, the round-eared sengi: on costs and trade-offs
TLDR
The results show that mate guarding is the predominant male tactic in round-eared sengis, however, since mate guarding imposed costs, males may balance benefits and costs associated with guarding by varying their effort in relation to their physical capabilities and the competitive environment.

Seasonal variation in selection on male calling song in the field cricket, Gryllus rubens
TLDR
It is suggested that males that call for long periods attract more females in autumn but not in spring, which means that seasonal variation in both natural and sexual selection has resulted in seasonal differences in male calling behaviour. Expand
Mating behavior of Columbian ground squirrels. I. Multiple mating by females and multiple paternity
TLDR
Patterns of multiple mating by female Columbian ground squirrels were investigated by observing mating behavior intensively over 5 years, and data suggest that mate choice for "good genes" via sperm competition is the most plausible benefit ofmultiple mating for females. Expand
Postcopulatory mate guarding by vocalization in the Formosan squirrel

TLDR
The Formosan squirrel, Callosciurus erythraeus thaiwanensis, emitted different vocalizations in response to terrestrial and aerial predators and snakes, and none of the ten characters of duration and frequency measured differed between the two calls. Expand
Postcopulatory vocalizations of fallow bucks: who is listening?
TLDR
It is found that PCVs declined as males reached the end of their mating success, therefore suggesting that PCV are more likely to be involved in transmitting an intrasexual threat signal related to current condition and/or motivation. Expand
Why do male black-tailed prairie dogs (Cynomys ludovicianus) give a mating call?
TLDR
Notably, females that copulated with a calling male were significantly less likely to wean a litter and Coterie size varied inversely with calling. Expand

Evaluating influences on the territorial behavior of male Columbian ground squirrels in Southwestern Alberta, Canada found that females mated first with a dominant male on whose territory they resided, but mating pairs were not exclusive as females usually mated with additional males. Expand
Ultrasonic vocalizations by male hamsters: parameters of calling and effects of playbacks on female behaviour
TLDR
Results provide evidence that males utter ultrasonic vocalizations that enhance lordosis during extended sexual interactions, and that the patterns of male calling are consistent with behaviours that maintain receptivity and ensure successful fertilization. Expand
Vocalizations of Belding's ground squirrels (Spermophilus beldingi)
TLDR
Sonagrams of trills occurring in agonistic contexts suggest that a third general category of trill may exist, but agonistic trills were more variable than either anti-predator or post-copulatory trills. Expand
Temporal overlap of female kin in Columbian ground squirrels (Spermophilus columbianus)
TLDR
Life history traits of S. columbianus suggest an adult female kin cluster unlike that found for other species of Spermophilus in which littermate sisters are common, which would predict a social system strorgly influenced by nepotism. Expand

TLDR
The spacing system and associated aggressive behavior of male Columbian ground squirrels in southwestern Alberta for the 2 months following emergence from hibernation is described to maintain spatiotemporal territories. Expand
