Mother-to-daughter transmission of hygiene in mandrills

Clemence Poirotte & Marie Charpentier
Social animals are particularly exposed to infectious diseases. Pathogen-driven selection pressure has thus favoured the evolution of behavioural adaptations to decrease transmission risk, such as “social distancing”. Yet, such strategy might deprive individuals from valuable social interactions, generating a cost-benefit trade-off between pathogen avoidance and social opportunities. Recent studies revealed that hosts differ in the expression of these behavioural defences but the determinants driving such inter-individual variation remain poorly understood. Using 5 years of detailed...

Mandrill mothers associate with infants who look like their own offspring using phenotype matching

Marie Charpentier, Clémence Poirotte, Berta Roura-Torres, Paul Amblard-Rambert, Eric Willaume, Peter Kappeler, François Rousset & Julien Renoult
Behavioral discrimination of kin is a key process structuring social relationships in animals. In this study, we provide a first example of discrimination towards non-kin by third-parties through a mechanism of phenotype matching. In mandrills, we recently demonstrated increased facial resemblance among paternally-related juvenile and adult females indicating adaptive opportunities for paternal kin recognition. Here, we hypothesize that mothers use offspring’s facial resemblance with other infants to guide offspring’s social opportunities towards similarly-looking ones. Using...

Cleavage of SARS-CoV-2 spike protein mutants

Markus Hoffmann, Prerna Arora, Sidarovich Anzhalika, Luise Graichen, Bojan Hörnich, Alexander Hahn & Stefan Pöhlmann
Several SARS-CoV-2 variants emerged that harbor mutations in the surface unit of the viral spike (S) protein that enhance infectivity and transmissibility. Here, we analyzed whether ten naturally-occurring mutations found within the extended loop harboring the S1/S2 cleavage site of the S protein, a determinant of SARS-CoV-2 cell tropism and pathogenicity, impact S protein processing and function. None of the mutations increased but several decreased S protein cleavage at the S1/S2 site, including S686G and...

Relationship between genome-wide and MHC class I and II genetic diversity and complementarity in a nonhuman primate

Rachel Petersen, Christina Bergey, Christian Roos & James Higham
Although mate choice is expected to favor partners with advantageous genetic properties, the relative importance of genome-wide characteristics, such as overall heterozygosity or kinship, versus specific loci, is unknown. To disentangle genome-wide and locus-specific targets of mate choice, we must first understand congruence in global and local variation within the same individual. This study compares genetic diversity, both absolute and relative to other individuals (e.g., complementarity), assessed across the genome to that found at the...

Bergey, Jeffrey Rogers, Jane E. Phillips-Conroy, Clifford J. Jolly, Amanda D. Melin, Jay F. Storz … & Noah Snyder-Mackler
Primates have adapted to numerous environments and lifestyles but very few species are native to high elevations. Here, we investigated high-altitude adaptations in the gelada (Theropithecus gelada), a monkey endemic to the Ethiopian Plateau. We examined genome-wide variation in conjunction with measurements of haematological and morphological traits. Our new gelada reference genome is highly intact and assembled at chromosome-length levels. Unexpectedly, we identified a chromosomal polymorphism in geladas that could potentially contribute to reproductive barriers...

No evidence that grooming is exchanged for coalitionary support in the short- or long-term via direct or generalized reciprocity in unrelated rhesus macaques

William O'Hearn, Angelina Ruiz-Lambides, Michael Platt & Lauren Brent
Reciprocity is a prominent explanation for cooperation between non-kin. Studies seeking to demonstrate reciprocity often focus on direct reciprocity in the timescale of minutes to hours, whereas alternative mechanisms like generalised reciprocity and the possibility of reciprocation over longer timescales of months and years are less often explored. Using a playback experiment, we tested for evidence of direct and generalised reciprocity, across short and longer timescales. We examined the exchange of grooming for coalitionary support...
