Reproductive Senescence in Two Lemur Lineages
Frontiers in Ecology and Evolution, 2022 The relationship between age and reproductive performance is highly variable across species. Humans and some cetaceans exhibit an extreme form of reproductive senescence in that female reproduction ceases years or even decades before average life ...

The ant’s weapon improves honey bee learning performance
Scientific Reports, 2023 Formic acid is the main component of the ant’s major weapon against enemies. Being mainly used as a chemical defense, the acid is also exploited for recruitment and trail marking. The repelling effect of the organic acid is used by some mammals and birds

Sex differences in audience effects on anogenital scent marking in the red-fronted lemur
Scientific Reports, 2022 How the presence of conspecifics affects scent mark deposition remains an understudied aspect of olfactory communication, even though scent marking occurs in different social contexts.

Active anti-predator behaviour of red titi monkeys (Plecturocebus cupreus) [PDF]
Primate Biology, 2019 Due to their inconspicuous behaviour and colouration, it has been assumed that titi monkeys' main anti-predator behaviour is passive crypsis and hiding.

Infants as Social Magnets: The Influence of Births on Social Interactions in Redfronted Lemurs (Eulemur rufifrons). [PDF]
Am J PrimatolABSTRACT Infant survival is an important component of parental fitness in iteroparous species with slow life histories. From the infant's perspective, survival can be more or less directly influenced by the social environment, with group members potentially representing either a threat or a buffer against external stressors.

Individual identification of bony fishes using unique body markings: Implications and applications. [PDF]
J Fish BiolAbstract The natural variation in animal body markings, such as spots, stripes and blotches, offers a powerful tool for researchers, conservationists, citizen scientists and resource managers to distinguish specific individuals within species. By building libraries of photo‐identified individuals, we can track and differentiate individuals over time ...

Life on the edge: behavioural and physiological responses of Verreaux's sifakas (Propithecus verreauxi) to forest edges [PDF]
Primate Biology, 2021 Forest edges change micro-environmental conditions, thereby affecting the ecology of many forest-dwelling species. Understanding such edge effects is particularly important for Malagasy primates because many of them live in highly fragmented forests ...
