Abstract
A key aspect of a primate’s ecology is its food source, the very nature of which is spatially and seasonally dependent and may be affected by anthropic pressures. One of the most endangered, yet best-studied, strepsirrhine primates is the ring-tailed lemur (Lemur catta), a species that has experienced significant human-induced habitat loss over many decades. To help understand feeding variability across time and space, I present a literature review of plant species (and parts) fed on by ring-tailed lemurs at nine sites in Madagascar: Ambatotsirongorongo, Andringitra Massif, Anja Reserve, Antserananomby, Berenty Reserve, Beza Mahafaly Special Reserve, Cap Sainte-Marie, Tsaranoro Valley Forest, and Tsimanampetsotsa National Park. I gathered literature using keyword searches on Google Scholar ( https://scholar.google.com/ ) and verified scientific names using the “Catalogue of the Plants of Madagascar” ( http://legacy.tropicos.org/Project/Madagascar ). From 24 studies, I identify 221 genera and 241 species of consumed plants, with 92 genera and 70 species consumed at two or more sites. Based on the available distribution data, 63% of species are endemic and 22% native. Sixty-seven plants are known only by Malagasy common names and excluded from analyses. When authors identify the plant tissue consumed, 52% of species in the diet are represented by a single tissue type, typically leaves (mature and immature) or fruit (ripe or unripe). This review highlights the importance of studying multiple populations when creating dietary summaries of species and should prove valuable to those exploring ecological trends and habitat use by ring-tailed lemurs.
