Male Reproductive Strategies in Black and Gold Howler Monkeys (Alouatta caraya) [PDF]

open access: yes, 2013
Behavioral and demographic factors such as group size, social structure, dispersal patterns, and mating systems affect male reproductive success. In the present study, we analyze the relationship between social structure, genetic relatedness of adult ...

Behavioral characterization of opioid mixed agonist-antagonists [PDF]

open access: yesDrug and Alcohol Dependence, 1987
The effects of agonists and partial agonists of both mu and kappa receptor systems are described in several behavioral tests in rhesus monkeys. Procedures measuring drug discrimination, drug self-administration, drug dependence, and drug-induced analgesia are differentially sensitive to the agonist and antagonist effects of various opioids.

From molecule to behavior: Brain aromatase (cyp19a1b) characterization, expression analysis and its relation with social status and male agonistic behavior in a Neotropical cichlid fish

open access: yesHormones and Behavior, 2017
&NA; The enzyme aromatase, responsible for the conversion of C19 androgens to C18 estrogens, exists as two paralogue copies in teleost fish: Cyp19a1a mostly expressed in the gonads, referred as gonadal aromatase, and Cyp19a1b, mostly expressed in the ...

Quantifying agonistic interactions between group-housed animals to derive social hierarchies using computer vision: a case study with commercially group-housed rabbits

open access: yesScientific Reports, 2023
In recent years, computer vision has contributed significantly to the study of farm animal behavior. In complex environments such as commercial farms, however, the automated detection of social behavior and specific interactions between animals can be ...

NMDA channel behavior depends on agonist affinity [PDF]

open access: yesThe Journal of Neuroscience, 1992
We have compared the kinetic properties of NMDA receptor channels activated by exogenous agonists with those activated synaptically. Short (4 msec) applications of L-glutamate to outside-out patches from hippocampal neurons evoked currents that decayed with a double exponential time course that was controlled by both the unbinding rate of agonist and ...

open access: yesAnimals, 2023
In intensive swine production systems,, the practice of regrouping unfamiliar pigs is common, often leading to aggressive behavior. Although the effect of different musical genres composed for humans has been evaluated in pigs to mitigate aggression ...

Agonistic behavior of Hammond’s Flycatcher (Empidonax hammondii) on Pine Toad (Incilius occidentalis)

open access: yesHuitzil, 2019
Aggression is an important agonistic behavior in animals, with influence on the survival and reproductive success of the species. Flycatchers (Tyrannidae) exhibit highly visible social behaviors, but little has been documented on their agonistic behavior.
