Sentence examples for observations of mating from inspiring English sources

These results reveal that the time course of accessory gland recovery corresponds to field observations of mating behaviour and suggest that accessory gland size may limit male mating frequency in C. dalmanni.

Detailed observations of mating behaviour and molecular analyses of paternity patterns might provide useful information about the risk and outcome of sperm competition, but such data are relatively costly to obtain and therefore not available for very many species.

Since direct observations of mating in the wild are not possible, we assayed the frequency of outcrossing in individual trials in which two or three asci were placed in contact with one another, and in mass mating assays of dense sporulated populations using natural strains.

Precopulatory isolation was determined from observations of mating behavior, and postcopulatory isolation, from progeny data.

All observations of mating behaviour commenced at the start of the dawn period.

Furthermore, we demonstrate that the timecourse of post-copulatory recovery of accessory gland size closely mirrors field observations of mating patterns in C. dalmanni.

The location is the most probable site where population subdivision occurred, and observation of mating behavior in the location would give clues to the diversification mechanism occurring in those marginal seas.

Secondary screening of putative mutants by observation of mating behavior allowed us to determine those mutants with defects in sperm transfer.

The occurrence of such a selection effect among ferns has been suggested before based on observations of mating-system variation among populations e.g. [ 22, 46, 47].

Lionesses aren't bound by African weather cycles when they reproduce, and therefore observations of lions mating can take place any time of the year.

Giving a little sediment and minute artificial tubes for one male and two females of the callianassid, Nihonotrypaea harmandi, in small transparent containers under illumination, observations and video-recordings of mating behaviors were made for the one pair three times, for the first time for Axiidea.
