Using remote seminars to teach animal behavior

Loren D. Hayes, Leticia Aviles, Eduardo Fernandez‐Duque, Maren Huck, more

In response to the COVID‐19 crisis, numerous academic conferences and seminars were moved online. Some remote (online) seminars have the aim to be maintained permanently after the pandemic, offering weekly opportunities for scientists, postdocs, and students to learn about research and to improve global networking. Remote seminars are a good option to promote inclusion and diversity, allowing students...

The evolution of pair‐living, sexual monogamy, and cooperative infant care: Insights from research on wild owl monkeys, titis, sakis, and tamarins

Eduardo Fernandez‐Duque, Maren Huck, Sarie Van Belle, Anthony Di Fiore

American Journal of Physical Anthropology > 171 > S70 > 118 - 173

“Monogamy” and pair bonding have long been of interest to anthropologists and primatologists. Their study contributes to our knowledge of human evolutionary biology and social evolution without the cultural trappings associated with studying human societies directly. Here, we first provide an overview of theoretical considerations, followed by an evaluation of recent comparative studies of the evolution...

The floater's dilemma: use of space by wild solitary Azara's owl monkeys, Aotus azarae, in relation to group ranges

Maren Huck, Eduardo Fernandez-Duque

Animal Behaviour > 2017 > 127 > C > 33-41

The fate and behaviour of animals that leave their natal group (‘floaters’) is usually poorly understood, which can limit the understanding of a species' population dynamics. Attempted immigrations can have serious negative effects on residents who therefore may forcibly reject intruders. Consequently, floaters face a dilemma: they need to leave their natal range to find a breeding territory while...

Relationship between moonlight and nightly activity patterns of the ocelot (Leopardus pardalis) and some of its prey species in Formosa, Northern Argentina

Maren Huck, Cecilia P. Juárez, Eduardo Fernández-Duque

Mammalian Biology - Zeitschrift f�r S�ugetierkunde > 2017 > 82 > C > 57-64

The moon can profoundly influence the activity patterns of animals. If predators are more successful under bright moonlight, prey species are likely to respond by shifting their own activity patterns (predator-avoidance hypothesis). However, the assumption that prey will necessarily avoid full-moon nights does not take into account that moonlight also allows prey to more easily detect predators, and...

Double effort: Parental behavior of wild Azara's owl monkeys in the face of twins

Maren Huck, Mari Van Lunenburg, Victor Dávalos, Marcelo Rotundo, more

American Journal of Primatology > 76 > 7 > 629 - 639

In species of mammals that habitually bear single offspring, like most anthropoid primates, the occurrence of twins is expected to impose considerable energetic costs on the caretakers. The question then arises of how caregivers cope with the potentially increased costs of raising twins. These increased costs should lead to differing developmental rates in twins when compared to singletons, and/or...

Children of divorce: effects of adult replacements on previous offspring in Argentinean owl monkeys

Maren Huck, Eduardo Fernandez-Duque

Behavioral Ecology and Sociobiology > 2012 > 66 > 3 > 505-517

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 immatures than to genetic offspring, unless caring also serves as a mating strategy. Furthermore, because an intruder will be a potential mate for opposite-sexed offspring, relationships...

Growth and Development in Wild Owl Monkeys (Aotus azarai) of Argentina

Maren Huck, Marcelo Rotundo, Eduardo Fernandez-Duque

International Journal of Primatology > 2011 > 32 > 5 > 1133-1152

Life history predicts that in sexually dimorphic species in which males are the larger sex, males should reach sexual maturity later than females (or vice versa if females are the larger sex). The corresponding prediction that in sexually monomorphic species maturational rates will differ little between the sexes has rarely been tested. We report here sex differences in growth and development to adulthood...

Analyses of least cost paths for determining effects of habitat types on landscape permeability: wolves in Poland

Maren Huck, Włodzimierz Jędrzejewski, Tomasz Borowik, Bogumiła Jędrzejewska, more

Acta Theriologica > 2011 > 56 > 1 > 91-101

Determining ecological corridors is crucial for conservation efforts in fragmented habitats. Commonly employed least cost path (LCP) analysis relies on the underlying cost matrix. By using Ecological Niche Factor Analysis, we minimized the problems connected with subjective cost assessment or the use of presence/absence data. We used data on the wolf presence/absence in Poland to identify LCPs connecting...

Habitat suitability, corridors and dispersal barriers for large carnivores in Poland

Maren Huck, Włodzimierz Jędrzejewski, Tomasz Borowik, Małgorzata Miłosz-Cielma, more

Mammal Research > 2010 > 55 > 2 > 177-192

Carnivores are often particularly sensitive to landscape fragmentation. Ecological corridors may help to connect local populations, ensuring gene flow and retaining viable meta-populations. We aimed to establish habitat suitability models for two large carnivores in Poland, the grey wolf Canis lupus Linnaeus, 1758 and the Eurasian lynx Lynx lynx Linnaeus, 1758, based on ecological niche factor analysis...

Characterization and Social Correlates of Fecal Testosterone and Cortisol Excretion in Wild Male Saguinus mystax

Maren Huck, Petra Löttker, Eckhard W. Heymann, Michael Heistermann

International Journal of Primatology > 2005 > 26 > 1 > 159-179

Reproductive success in male primates can be influenced by testosterone (T) and cortisol (C). We examined them in wild Saguinus mystax via fecal hormone analysis. Firstly, we wanted to characterize male hormonal status over the course of the year. Further we tested the influence of the reproductive status of the breeding female, social instability, and intergroup encounter rates on T levels, comparing...

Endocrine Correlates of Reproductive Status in Breeding and Nonbreeding Wild Female Moustached Tamarins

Petra Löttker, Maren Huck, Eckhard W. Heymann, Michael Heistermann

International Journal of Primatology > 2004 > 25 > 4 > 919-937

In callitrichid primates, reproduction is usually restricted to a single female per group. Reproductive rate is high and the occurrence of a postpartum estrus can lead to simultaneous lactation and pregnancy. In contrast, nonreproductive females often show ovarian inactivity. However, most studies on callitrichid reproductive physiology have been conducted in captivity, where conditions differ considerably...
