Honest signaling in mouse lemur vocalizations?
Animal vocalizations may provide information about a sender’s condition or motivational state and, hence, mediate social interactions. In this study,...

Nocturnality and Activity Budgets of Owl Monkeys in Tropical Ecosystems
The subtropical populations of owl monkeys (Aotus) and some lemurs have flexible patterns that include activity during both day and night. Early...

Infant Development and Maternal Care in Wild Verreaux’s Sifaka (Propithecus verreauxi)
Investigating factors influencing infant physical and social development is important to elucidate primate adaptations and life history evolution....

Sources of variation in social tolerance in mouse lemurs (Microcebus spp.)
BackgroundSocial tolerance strongly influences the patterns of affiliation and aggression in animal societies. However, not much is known about the...

Agonistic vocalization behaviour in the male ring-tailed lemur (Lemur catta)
Vocalizations are used by group-living animals as aggressive and submissive signals during agonistic interactions, and are also used to maintain...

Less is more: lemurs (Eulemur spp.) may benefit from loss of trichromatic vision
AbstractVertebrate color vision is an ideal system for studying the gains and losses of genetic variation across lineages and impacts on behavior....

Using Utilitarian Plants for Lemur Conservation
Nature and species conservation often conflict with intensive natural resource or land use. Many protected areas are too small for long-term...

Comparative analyses of two primate species diverged by more than 60 million years show different rates but similar distribution of genome-wide UV repair events
BackgroundNucleotide excision repair is the primary DNA repair mechanism that removes bulky DNA adducts such as UV-induced pyrimidine dimers....

Insights from macroevolutionary modelling and ancestral state reconstruction into the radiation and historical dietary ecology of Lemuriformes (Primates, Mammalia)
BackgroundLemurs once rivalled the diversity of rest of the primate order despite thier confinement to the island of Madagascar. We test the...

Comfort Behavior of Black-and-White (Varecia variegata variegata) and Red (Varecia variegata rubra) Ruffed Lemurs (Primates, Lemuridae)
Abstract —Knowledge of grooming makes it possible to characterize the intragroup social connections of lemurs and accurately form groups in captivity....

A role for gut microbiota in host niche differentiation
If gut microbes influence host behavioral ecology in the short term, over evolutionary time, they could drive host niche differentiation. We explored...

Comparative ACE2 variation and primate COVID-19 risk
The emergence of SARS-CoV-2 has caused over a million human deaths and massive global disruption. The viral infection may also represent a threat to...

Coming into Focus
Petrus had grown up a biologist like perhaps no other person. Without a single tree to touch or be tutored by for three decades, he knew enough from...

Interrelationship among spatial cohesion, aggression rate, counter-aggression and female dominance in three lemur species
AbstractHow social and ecological factors are associated with variation in dominance style across species of animals has been studied frequently, but...

Through the Looking Glass: Effects of Visitors on Primates in Zoos
Daily exposure to visitors as well as caretakers makes the zoo environment a unique setting for primates in human care. Understanding how visitors...

The Past, Present, and Future of the Primate Pet Trade
Pet primates are those kept typically for companionship, enjoyment, and status, although their uses as pets may extend beyond these parameters. The...

Fecal contamination, parasite risk, and waterhole use by wild animals in a dry deciduous forest
AbstractWaterholes are critically important to animal survival in dry habitats but are also a potential source of parasite exposure. Avoiding feces...
