Ultrasonography-guided oocyte recovery in owl monkeys (aotus azarai infulatus)
(2021-04-01)
The study evaluated an echo-guided oocyte recovery technique in owl monkeys. Twelve females were selected for the transabdominal ovum retrieval technique. This procedure collected twenty-six follicles, of which nine oocytes ...
Ovarian and Uterine Ultrasonography in Aotus azarai infulatus
(Springer/plenum Publishers, 2014)
AVPR1A Sequence Variation in Monogamous Owl Monkeys (Aotus azarai) and Its Implications for the Evolution of Platyrrhine Social Behavior
(Springer, 2010-09)
The arginine vasopressin V1a receptor gene (AVPR1A) has been implicated in increased partner preference and pair bonding behavior in mammalian lineages. This observation is of considerable importance for studies of social ...
Children of divorce: Effects of adult replacements on previous offspring in Argentinean owl monkeys
(Springer, 2012-03)
According to the Evolutionary Theory of the Family, the replacement of one pair-member by an intruder may have profound consequences for the existing offspring. Step-parents are expected to provide less care towards unrelated ...
Food transfers to young and mates in wild owl monkeys (Aotus azarai)
(Wiley-liss, Div John Wiley & Sons Inc, 2008-01)
Accounts of food sharing within natural populations of mammals have focused on transfers to offspring or transfers of food items that are difficult to obtain (such as meat). Five groups of socially monogamous owl monkeys ...
Prolactin receptor gene diversity in Azara's owl monkeys (Aotus azarai) and humans (Homo sapiens) suggests a non-neutral evolutionary history among primates
(Springer/plenum Publishers, 2013-10-08)
Although paternal care is rare in mammals, males of several primate taxa exhibit high degrees of this behavior. Studies of many species of vertebrates found a positive correlation between prolactin (PRL) levels and paternal ...
Correlates of genetic monogamy in socially monogamous mammals: insights from Azara’s owl monkeys
(The Royal Society, 2014-02)
Understanding the evolution of mating systems, a central topic in evolutionary biology for more than 50 years, requires examining the genetic consequences of mating and the relationships between social systems and mating ...
Hematological, hepatic, and renal evaluation in Aotus azarai infulatus
(Wiley-Blackwell, 2014)
Costs and Benefits of Radio-collaring on the Behavior, Demography, and Conservation of Owl Monkeys (Aotus azarai) in Formosa, Argentina
(Springer, 2010-10)
The benefits to researchers of capturing and collaring free-ranging primates are numerous, but so are the actual and potential costs to the individuals. We aimed to 1)evaluate quantitatively the possible demographic long-term ...
