Abstract

The pantropical genus Ixora is highly diverse, with several species endemic to the Philippines.Owing to their endemic nature, many of these species are endangered and little is known about their basic biology. This study aimed to establish baselineinformation about the bioclimatic niches of Ixora species endemic to the Philippines, determine suitable areas and potential range shifts under future climate conditions, and identify priority areas for conservation and future research. Locality records of 12 endemic Ixora species from the Philippine archipelago were analyzed, with a particular focus on the five mostabundant species I. auriculata, I. bartlingii, I. cumingiana, I. macrophylla, and one island endemic species, Ixora palawanensis. Bioclimatic variables from the WorldClim database at 2.50 resolution were used, with a focus on annual means and seasonality of temperatureand precipitation as well as precipitation of the warmest quarter. Analysis of the relationships of the species locations with the bioclimatic variables showed that the bioclimatic niches of the five focal Ixora species generally had narrow temperature and wider precipitation niches. Species distribution modelingwith the model Maxent suggested that I. auriculata and I. bartlingii will likely shift their geographic distributions southwards under predicted levels of climate change, while I. cumingiana and I. macrophylla were found to likely expand their ranges. Ixora palawanensis, in contrast, was predicted to decrease its potential distribution with future climate change. Further, results of species distribution modelingfor the rare endemic Ixora species I. bibracteata,I. chartacea, I. ebracteolata, I. inaequifolia, I. longistipula, I. luzoniensis, and I. macgregorii were presented,which, however, had much less observation points and therefore only provide a first estimate ofpotential species distributions. The generated potential habitat suitability maps can assist policy makers in designing conservation strategies for the species andin identifying areas with potential to withstand climatechange until at least 2080.
