Dear All,
Quick reminder that today we have a seminar led by Ashleigh Messenger (University of Stirling) about her PhD study entitled "The importance of personality in ex-situ ring-tailed lemurs (Lemur catta)" - abstract below. The meeting will be held in-person in the Psychology common room with a possibility of joining online.
Abstract
Ex-situ conservation of ring-tailed lemurs (Lemur catta) is becoming increasingly important, due to threats in the wild (LaFleur & Gould, 2020). However, there are many difficulties associated with the husbandry of this species, due to their complex social structure (Sauther & Sussman, 1993) and aggressive tendencies (Gould, Sussman & Sauther, 2003).
Personality has been used as an indicator of welfare in many species. However, it is often difficult to determine which aspects of personality are the most relevant in a given species. The trait theory of personality can distinguish differences between species (allowing for cross-species comparison) and acknowledges individual differences within a given species (Tetley & O’Hara, 2012). This has been applied successfully to many species, including primates King & Figuerdo, 1997; Weiss et al., 2006; 2009; 2011) However, there has thus far been no attempt to describe personality structure in ring-tailed lemurs. This research aims to uncover the major traits of ring-tailed lemur personality by utilising these established methods.

Dear All,
This Wednesday (4pm) we have a seminar led by Berta Roura-Torres (Georg-August University Göttingen) entitled "Early challenges shape fitness trajectories in mandrills" (abstract below). The meeting will be held online (link below).
Abstract:
Adverse events during early life that reduce access to resources or hinder their allocation can have lasting effects on health, survival, and reproduction in mammals, including humans, and the accumulation of such challenges often has stronger consequences than single events. Using a 12-year dataset from a wild population of mandrills (Mandrillus sphinx), a cercopithecine primate, we examined how early life adversity (ELA) influences survival during infancy (under 1 year) and juvenility (1–4 years), female age at first reproduction, and male age at dispersal. We identified seven types of adversity, covering maternal, social, environmental, and demographic factors, and analyzed both their cumulative and individual effects. Infant survival was affected solely by maternal loss, with cumulative ELA showing no impact. Female reproductive timing responded to specific early-life conditions: individuals with a closely spaced younger sibling, born to low-ranking mothers, born in years with reduced rainfall, or with higher cumulative ELA reproduced later, whereas females born to primiparous mothers reproduced earlier. In contrast, male age at dispersal showed no effect of ELA. Overall, these findings indicate that cumulative adversity does not consistently shape survival in mandrills, but it can influence female reproductive timing. They further suggest that the consequences of early-life challenges vary across life-history traits and sexes, with particular conditions sometimes playing a larger role than the accumulation of adversity in shaping fitness. Finally, this talk presents preliminary results on early physical development during infancy, obtained using an innovative non-invasive approach based on a trained AI model applied to photographic portrait, which may represent a potential pathway linking ELA to later-life survival and reproductive outcomes.
