It is distributed from approximately 27°18’S – 70°25’W in the north (Atacama) to 36°00’S – 73°7’W in the south (BíoBío). We report the finding of a cranium in excellent conditions, which is the first record of this species in the coastal shrubby Mediterranean desert of the Antofagasta Region. -

Extension of distribution range in Chile Nuevo hallazgo de Abrocoma bennetti murrayi (Rodentia, Abrocomidae) en la Región de Atacama. Extensión de su rango de distribución en Chile Pablo Valladares1, Claudio Campos2 ABSTRACT The present note reports the first record of the rodent Abrocoma bennetti (Waterhouse 1837) for the Copiapó Valley, located between the cities of Copiapó and Caldera, Chile. Specimens were captured and then released to their natural environment. This record extends the northern and northwestern distribution limits of this rodent from Vallenar to Copiapó (ca. 145 km) and from Ramadilla to Copiapó (ca. 120 km), respectively. Other species collected were Oligoryzomys longicaudatus and Abrothrix olivaceus. We present a map of the new distribution range for this species based on taxonomic collections and previously published papers. Key words: chinchilla rat, Abrocoma, Copiapó, distribution. RESUMEN En la presente nota reportamos el primer registro de Abrocoma bennetti para el valle de Copiapó. Los especímenes fueron capturados y luego liberados a su ambiente natural en la localidad de Piedra Colgada. Este nuevo registro extiende su rango de distribución desde el valle de Vallenar a Copiapó en 145 kilómetros, y desde Ramadilla a Copiapó en 120 kilómetros, respectivamente.

Field interviews were con- ducted with local villagers, in parallel with an intensive search for direct and/or indirect signs of the 2 species. Confirmed records for the Andean cat suggest that the species is mainly restricted to the high Andean region of Bolivia (elevations above 4100 m), whereas the pampas cat can be found both in this region and at lower elevations. Most of the confirmed records were for the pam- pas cat, suggesting that it is more abundant than the Andean cat. Both species are generally referred to by local people as ‘titi’ and are culturally associated with Earth’s abundance and fertil- ity. -

Phylogeny and Evolutionary Patterns of South American Octodontoid Rodents
Phylogeny and evolutionary patterns of South American octodontoid rodents DIEGO H. VERZI, A. ITATÍ OLIVARES, and CECILIA C. MORGAN Verzi, D.H., Olivares, A.I., and Morgan, C.C. 2014. Phylogeny and evolutionary patterns of South American octodontoid rodents. Acta Palaeontologica Polonica 59 (4): 757–769. Octodontoidea is the most diverse clade of hystricognath rodents, and is richly recorded in South America since at least the Oligocene. A parsimony-based morphological phylogenetic analysis of a wide range of extant and extinct octodon- toids recovered three major clades, here recognised as Echimyidae, Octodontidae, and Abrocomidae. Taxa previously assigned to Echimyidae or Octodontoidea incertae sedis are here interpreted for the first time as early representatives of Ctenomyinae (Octodontidae), Octodontinae or Abrocomidae. Based on our results, we estimate the divergence of octodontoid families and subfamilies to have occurred during the Late Oligocene, which is consistent with molecular estimates, but older than previous inferences based on the fossil record. Contrary to previous suggestions, we show the first appearances of modern members of Abrocomidae, Octodontinae and Ctenomyinae to be distinctly decoupled from the origin of these clades, with different stages in the evolutionary history of octodontoids seemingly following distinct phases of palaeoenvironmental change. Depending on the phylogenetic pattern, fossils from the stage of differentiation bear evolutionary information that may not be provided by crown groups, thus highlighting the unique and important contribution of fossils to our understanding of macroevolutionary patterns.

Behavioral Ecology of Grey Eagle-Buzzards, Geranoaetus

JAKSI~ Departamentode Ecologfa,Universidad Catblica de Chile, Casilla 114-D. Santiago, Chile Abstract. Throughout 1 year we observedthe behavioral ecologyof Grey Eagle-Buzzards (Geranoaetusmelanoleucus) in central Chile. The eagles’ activity period was bimodal, with peaks in mid-morning and mid-afternoon. During the day they spent most of their time flying (except during winter), extensively soaringin thermal and wind updrafts, rarely using flapping flight. Eagles appeared to select specific physiographic features that favored the presenceof updrafts, particularly north- and west-facingslopes and ridge tops. Use of these featuresapparently was unrelatedto prey abundanceor vegetativecover. Prey were primarily large-sizedsmall mammals, and secondarilyreptiles and birds. Although aggressive,eagles were attackedby a number of speciesof other raptors. Comparison of the behavioral ecology of eaglesand of Nearctic buteoninesdemonstrated some marked differences,particularly in activity time and habitat use. Thesedifferences appear to be relatedto weatherconditions prevailingin montanevs. lowlandterrain.

Diets and Selectivity of Two Chilean Predators in the Northern Semi-Arid Zone
Revista Chilena de Historia Natural 60: 93-99, 1987 Diets and selectivity of two Chilean predators in the northern semi-arid zone Hábitos alimenticios y selectividad de dos depredadores chilenos en la zona semiarida nortina PETER L. MESERVE, EDWARD J. SHADRICK, and DOUGLAS A. KELT Department of Biological Sciences, Northern Illinois University, DeKalb, Illinois 60115-2861, USA ABSTRACT The diets of two common Chilean predators, the culpeo (Dusicyon culpaeus), and the Burrowing Owl or pequén (Athene cunicularia) were analyzed by identification of the contents of 53 scats, and 19 pellets, respectively, collected during June 1985 in Parque Nacional Fray Jorge, Coquimbo Province (IV Region), Chile. Small mammals made up the ma- jority of prey items for both predators. Comparisons of proportions of identified small mammal prey remains with availability of small mammals in the semi-arid thorn scrub community as determined by snap-trapping indicated strong selectivity for some prey species. Skulls and teeth of the degu (Octodon degu), and the chinchilla rat (Abrocoma bennetti) were significantly overrepresented in the scats/pellets of both predators. This indicates that certain prey types may be more common in predator diets due to attributes such as body size and/or their vulnerability in the natural community. Although European hares (Lepus capensis) are present in the park, no remains were found in the scats/pellets of either predator. Small mammals in this community are significantly smaller than their counter- parts in central mediterranean scrub communities: since they are still utilized, other aspects such as time of activity may influence incorporation into predator diets. Key words: Athene cunicularia, Dusicyon culpaeus, predators, small mammals, predator diets, Chile, mediterranean ecosystems. -

B. 0' Higgins 949, P. 13, Santiago, Chile. 3 Museo Nacional de Historia Natural, Interior Quinta Normal, Santiago, Chile. ABSTRACT Octodontoidea have 2n from 10 to 102, and NF from 16 to 202, the largest ranges known for a mammal family group. Although 4 out of the 7 genera have very similar karyotypes to the one found in Octodon de gus 2n=58, NF=116, other two genera are extremely divergent ones. We describe and compare here the undescribed chromosome data from seven specimens of Octodon lunatus 2n=78, NF=128, and of thirteen specimens of Abrocoma bennetti 2n=64, NF= 114, from the related monogenetic Abrocomidae. Karyotype and chromosome analysis based on shape, size, and G-, C-, and AgAs bands detected 20 and 7 telocentric pairs respectively. Most of these characters were previously unknown in non-Ctenomys octodontoids. Some large metacentric chromosomes differed among species, and the differences in G bands were more abundant than what would be expected from their 2n and NF. C bands were very heterogenous withinkaryotypes.
