Fidelity to territory and mate and the causes and consequences of breeding dispersal in American goshawk (Astur atricapillus).

PloS one May 22, 2025
Using mark-resight data, we investigated fidelity to territory and mate as well as breeding dispersal rates and the causes and consequences of breeding dispersal in a 20-year study of American goshawks (Astur atricapillus) in Arizona, USA. Generalize...

Identifying mating events of group-housed broiler breeders via bio-inspired deep learning models.

Poultry science Apr 4, 2025
Mating behaviors are crucial for bird welfare, reproduction, and productivity in breeding flocks. During mating, a rooster mounts a hen, which may result in the hen overlapping or disappearing from top-view of a vision system. The objective of this r...

Estrous detection by continuous measurements of vaginal temperature and conductivity with supervised machine learning in cattle.

Theriogenology Sep 27, 2018
This study aimed to evaluate the effectiveness of estrous detection technique based on continuous measurements of vaginal temperature (VT) and conductivity (VC) with supervised machine learning in cattle. The VT and VC of 17 cows in tie-stalls were m...

Female Choice Leads to a Switch in Oval Squid Male Mating Tactics.

The Biological bulletin Feb 9, 2018
Oval squids are polyandrous, with one female mating with multiple males during the spawning season. There are two alternative male mating tactics used by Sepioteuthis lessoniana. Larger males place spermatophores at the opening of the oviduct using a...

Mate choice and the operational sex ratio: an experimental test with robotic crabs.

Journal of evolutionary biology May 8, 2016
The operational sex ratio (OSR: sexually active males: receptive females) predicts the intensity of competition for mates. It is less clear, however, under what circumstances, the OSR predicts the strength of sexual selection - that is, the extent to...

Differential testosterone response to GnRH-induced LH release before and after musth in adult Asian elephant (Elephas maximus) bulls.

Theriogenology Dec 17, 2015
Bull elephants exhibit marked increases in testosterone secretion during musth, and studies have shown a heightened sensitivity of the testis to GnRH-stimulated testosterone production in musth compared to nonmusth males. However, activity of the hyp...

Analyzing animal behavior via classifying each video frame using convolutional neural networks.

Scientific reports Sep 23, 2015
High-throughput analysis of animal behavior requires software to analyze videos. Such software analyzes each frame individually, detecting animals' body parts. But the image analysis rarely attempts to recognize "behavioral states"-e.g., actions or f...
