A tooth wear-determined, but rainfall-mediated, onset of reproductive senescence is suggested, and the study indicates that even subtle changes in climate may affect reproductive success of rainforest species.

It is shown that folivorous primate species tend to exhibit more rapid dental development than comparably sized frugivores, and their dental development tends to be more advanced at weaning, and an important role for brain (rather than body) size as a predictor of both absolute and relative dental development is affirm.

It is proposed that the differing developmental schedules of folivorous and frugivorous lemurs may reflect different solutions to the ecological problem of environmental instability: some rely on a strategy of low maternal input and slow returns, while others rely onA strategy of high maternalinput and fast returns.
Dental use wear in extinct lemurs: evidence of diet and niche differentiation.
Paradox of peramorphic paedomorphosis: heterochrony and human evolution.
This paper reviews Gould's clock model for heterochronic processes and uses that model to develop simple matrix representations of growth and shape change and shows how neoteny can be diagnosed using such a matrix approach.

Holocene cave, marsh, and stream deposits on the island of Madagascar have yielded thousands of “subfossil” specimens that document recent megafaunal extinctions. Excavations conducted during the…

The results demonstrate that large body size in primates does not preclude exceedingly rapid dental development, and implies a pattern characteristic of Propithecus and other indrids—rapid dental development despite relatively prolonged gestation.
Schultz’s Unruly Rule: Dental Developmental Sequences and Schedules in Small-Bodied, Folivorous Lemurs
It is shown that a variety of processes allows the crowns of permanent teeth to form and to erupt into jaws that might appear to be too small to accommodate them, and Schultz’s rule, which presumes that eruption timing is dependent on the size of the jaw, will be delayed in species with slow-growing jaws.
