Sentence examples for copulation frequency in from inspiring English sources

To test this hypothesis, we collected data on meat sharing and copulation frequency in a group of wild chimpanzees in the Taï National Park, Côte d'Ivoire between 2003 and 2006.

The overall positive relationship between realized matings and mating attempts indicates that morph-specific copulation frequencies in the field do, to some extent, reflect the total number of previous male mating attempts (Fig 3).

Copulation frequency assays were performed in single-pair assays in chambers of 1 cm diameter for 10 min under constant light.

Understanding female choice and male-female meat sharing in species in which copulation frequency can be easily measured and dyadic transfers of meat can be directly quantified is likely to give us insight into the mechanisms driving the latter relationship in humans.

We did this to test alternative explanations to having a relationship between meat sharing and copulation frequency and additionally to reduce, in each case, the number of predictor variables included in the model.

Copulation frequency was calculated as percentage of flies in each condition that successfully copulated during the 10 min assay.

Overall, the predictor variables included in the model had a significant effect on copulation frequency (likelihood-ratio test: χ2 = 27.64, df = 4, N = 30, p<0.0001).

Overall, the predictor variables included in this model had a significant effect on copulation frequency (likelihood-ratio test: χ2 = 32.83, df = 7, N = 30, p<0.0001).

The original Wolbachia-infected wild-type strain was itself male-courtship defective, when tested in this assay with Oregon R females (giving a copulation frequency of only 57%).

Three additional females also had sexual swellings and copulated during the study but were excluded from analyses due to low copulation frequency (<15 copulations).

Instead, in the mating period male-to-female grooming correlated with the copulation frequency.
