According to the IUCN, about 60% of the ~500 primate species are threatened by extinction, and this is mainly the result of human activity
Environmental changes linked to human activities include landscape modifications, hunting and other interactions between human and non-human primates, and climate change:
Primates seem to be especially vulnerable to these rapid changes because of their slow life-histories and long generation times. On the other hand, primates show considerable behavioral flexibility, which may help them to respond to environmental change in an adaptive way (Kalbitzer & Chapman, 2018). The question as to how such flexibility may help animals to respond to environmental changes associated with the ‘Anthropocene’ is generally discussed in behavioral ecology (e.g. here or here), and I would like to contribute to this discussion by investigating how environmental changes affect breeding seasonality, infant survival and adaptive social behavior in different species of primates.
