Article
As currently understood, the genus Octodon contains five species degus, lunatus, bridgesii, pacificus, and ricardojeda. Previous phylogenetic studies suggest that genus specific diversity is underestimated. In order to evaluate the taxonomic diversity of Octodon, we implemented unilocus (cytochrome-b) and multilocus (cytochrome-b + 4 nuclear genes)...
Article
The caviomorph Octodon degus is likely the most studied Chilean mammal species. Several studies have centered in its natural history, ecology, behavior, and physiology; in addition, the species is used as model organism in biomedicine and neurobiology research. However, basic aspects such as its genetic and morphological variation throughout its di...

Se presenta una lista actualizada de los mamíferos vivientes con registros en Chile, compilada en diciembre de 2020. La lista incluye 163 especies silvestres agrupadas en 85 géneros, 31 familias y ocho órdenes. De estas especies, 20 son endémicas del país. También se provee la lista de 22 especies exóticas con poblaciones silvestres en Chile. Dado...
Article
We combine morphological (qualitative and quantitative data) and genetic (one mitochondrial and one nuclear gene) data from a large set of specimens of Octodon from the four currently recognized living species of the genus. The integration of the results (qualitative assessment, multivariate analysis of cranial measurements, and gene trees) allows...

The present study reports the southernmost record of Tomopeas ravus and the first capture of this species after more than 30 years since the last known report. This record extends the distribution of the species approximately 230 km south of the current known distributional range.
Article
Full-text available
The monotypic bat genera Platalina and Tomopeas are rare and known from few localities throughout their distributions. These species have not been recorded in the northern half of their distributions for the last 4 and 3 decades, respectively, suggesting local extirpation. Here we present new records for both taxa from a 2012 expedition conducted i...

The Neotropical bat genus Lophostoma (Phyllostomidae: Phyllostominae) currently includes seven species. Two taxa, Lophostoma aequatorialis and Lophostoma silvicolum occidentalis, occur west of the Andes in Ecuador and Peru. In the de-scription of L. aequatorialis, these two taxa were compared solely on the basis of morphology because DNA sequence d...

The role of fruit bats was evaluated in three habitat types of Cerros de Amotape National Park, Tumbes, Peru. The diet was quantified by analyzing the seeds found in fecal samples and testing the preference for plant resources, niche breadth, the importance of each bat species as dispersors, and the level of trophic niche overlap. We captured 33 sp...

En el Perú se reporta la presencia de 18 especies de murciélagos nectarívoros, sin embargo se cuenta con poca información sobre la dieta de estas especies. En este estudio se reporta por primera vez la dieta de los nectarívoros Glossophaga soricina, Lonchophylla hesperia y Anoura geoffroyi en el bosque seco ecuatorial y del bosque tropical del Pací...

We report the first record of Gracilinanus agilis (Mammalia: Didelphidae) for the department of Loreto, Peru. This represents the northermost record of the species. Se reporta el primer registro de Gracilinanus agilis (Mammalia: Didelphidae) para el departamento de Loreto, Perú; el cual representa el registro más septentrional conocido de la especi...

We present an annotated list for all land, aquatic and marine mammals known to occur in Peru and their dis- tribution by ecoregions. We also present species conservation status according to international organizations and the legal conservation status in Peru. At present, we record 508 species, in 13 orders, 50 families, and 218 genera, making Peru...

In the present work, Tricholeiperia peruensis. n sp. (Nematoda, Molineidae) is described on the basis of 25 collected specimens from 5 bat intestines of the Lophostoma silvicolum occidentalis species from Angostura, district of Pampas de Hospital, department of Tumbes, Peru. The new species is characterized by the morphology of the cephalic vesicle...

The bat fauna of the Pacific Tropical rainforest region in Peru is poorly known. Here we report noteworthy range extensions of 12 bat species, including: Diaemus youngi, Chrotopterus auritus, Micronycteris minuta, Mimon crenulatum, Vampyrum spectrum, Chiroderma salvini, Enchisthenes hartii, Noctilio leporinus, Thyroptera discifera, Eptesicus chiriq...

The european hare Lepus europaeus is an invasive species that has been reported for the southern departments of Arequipa and Tacna. In September of 2005, different coastal and highland areas of Tacna were visited to evaluate the presence of this species. Twenty nine transect were established but the species was only registered in two of them. Howev...

Restos fósiles del "zorro de Sechura" - llamado Dusicyon sechurae en este trabajo, actualmente atribuido al género Lycalopex - son conocidos en los yacimientos paleontológicos del Pleistoceno superior de La Brea (Provincia de Talara, Departamento de Piura, Perú) y La Carolina (Provincia de Guayas, Ecuador). A primera vista, estos fósiles no present...

El análisis de las comunidades de mamíferos presentes en el registro fósil de Rancho La Brea (Los Angeles, California, U.S.A.) y Pampa La Brea (Talara, Piura, Perú) permite emitir hipótesis en cuanto a los paleoambientes de estos dos grandes yacimientos fosilíferos y las eventuales diferencias entre ellos. Los cenogramas sugieren en ambos casos un...

Project
A report of the results obtained from an experimental infection of the domestic dog Canis familiaris, with Corynosoma obtuscens Lincicome, 1943, which is an acanthocephale of great infectious capacity and unspecific for the ultimate host, for which it may be considered a potential parasite for the people who eat raw fish as “cebiche”, a typical dish of our country, is given in the present work. The presence of mature eggs of C. obtuscens in the feces of a non-habitual host is reported for the first time. Key words: Corynosoma obtuscens, Experimental infection, Canis familiaris.
