  abstract = {{A}im {T}o investigate how {Q}uaternary climatic changes affected the habitats that support endemic tree species distributions in a tropical rain forest. {B}ased on past and present predicted species distributions, we assessed (1) whether climatic conditions may have supported species survival in the same area over the studied period, (2) the effect of ecological niche specialization on species-specific responses, and (3) the persistence of current populations in areas that were more climatically stable over time. {L}ocation {W}estern {G}hats, {W}estern {G}hats-{S}ri {L}anka {B}iodiversity {H}otspot, {I}ndia. {M}ethods {W}e assessed species' current bioclimatic preferences based on their occurrence data using {MAXENT} distribution modelling. {T}he models were projected onto past climatic conditions of the {L}ast {G}lacial {M}aximum ({LGM}) and the {L}ast {I}nterglacial ({LIG}) to assess the extent of changes in species' predicted distributions through time. {F}urther, we tested whether species' current occurrences were located non-randomly in pixels predicted to have been suitable in the past. {F}inally, we characterized species-specific responses in relation to plausible biogeographical scenarios. {R}esults {W}e identified three distinct scenarios of species' responses to past climate changes - stability, contraction and shift - depending on their bioclimatic preferences. {F}or high-elevation species, the cool, dry {LGM} was less restrictive than for medium-elevation and northern lowland species. {S}outhernmost species requiring minimal seasonality were restricted by higher {LIG} seasonality, and only predicted to have been present in {S}ri {L}anka at that time. {B}arring these southernmost narrow endemics, past suitable habitat, within which observed current occurrences are located, were predicted for most species. {M}ain conclusions {P}alaeoclimate modelling reveals the likely local persistence of most {W}estern {G}hats endemics over the last 150 kyr, a relatively recent period in this {P}aleogene refugium. {T}he large spectrum of bioclimatic preferences probably arose as a result of evolutionary events prior to the {Q}uaternary. {O}ur results highlight the need for further studies based on molecular phylogenetics in this relatively poorly studied biodiversity hotspot.},
