Honoring the Life and Legacy of Oliver P. Pearson
PATTERNS OF SMALL MAMMAL SPECIES RICHNESS IN MEDITERRANEAN AND TEMPERATE CHILE PATRONES EN LA RIQUEZA DE ESPECIES DE PEQUEÑOS MAMÍFEROS EN LAS REGIONES MEDITERRÁNEA Y TEMPLADA DE CHILE Hernán L. Cofré, Horacio Samaniego, and Pablo A. Marquet ABSTRACT While it is widely accepted that species richness and rarity are non‑randomly distributed across time, space, and taxa, it is by no means evident which are the factors affecting the distribution paerns of both aributes. In this study we analyze richness and rarity paerns of small mammals (rodents and marsupials) in Mediterranean and Temperate Chile. We test for the effect of environmental factors that may explain richness and endemism variability aer accounting for spatial autocorrelation. We also analyze the relationship between species traits and correlates of rarity (density and range size) aer accounting for phylogenetic relatedness. Our results show that energy input and to a lesser degree glaciations may explain richness paern of small mammals from forest habitats in Chile, whereas glaciations and topographic heterogeneity are associated with endemicity paerns. Both factors may explain the high richness found at 37° S and the low values at the southernmost tip of the continent. When phylogenetic relatedness was accounted for, the number of vegetation types was the only ecological trait significantly associated with density and latitudinal range. Our results reinforce the importance of energy availability and productivity in determining paerns in biodiversity. Key words: Chile, diversity, mammals, Mantel test, rarity, macroecology, phylogenetic effects RESUMEN Si bien la idea de que la riqueza y la rareza específica tienen una distribución no aleatoria con relación al tiempo, el espacio, y la taxonomía, no es para nada evidente cuáles son los factores que afectan los patrones de distribución de aquellos dos atributos. -

Species composition was compared among past and present assemblages. Also composition, as well as individual and population parameters were compared among island habi- tats. Specimens from archaeological sites included Oligoryzomys longicaudatus, Abrothrix sp., and Octodon pacificus, whereas Abrothrix longipilis, A. olivaceus, Oligoryzomys longicaudatus,and Geoxus valdivianus were captured. Higher richness was observed in intermediate-disturbed habitat. Body size and tail length, as well as body mass did not vary among island habitats for A. longipilis or A. olivaceus. Higher abundance was associated to less perturbed habitat. Key words: Octodon pacificus, archaeozoology, Isla Mocha, Chile Introduction Islands comprise an important part of the 1999).
