The genus Akodon is one of the most species-rich rodent lineages in South America. In Peru, this genus contains 14 species subdivided in two groups: aerosus and boliviensis. Akodon orophilus Osgood, 1913 (Rodentia: Cricetidae) is a member of the Akodon aerosus group that inhabits the northern Peruvian montane forest, but is poorly characterized and its distri-bution is vaguely known. We review the status of the species based on morphology, morphometric and karyology, and compared with all members of the Akodon aerosus clade from Peruvian montane forests. As a result, we provide a com-plete redescription of A. orophilus, present new information on its natural history, restrict its distribution to the east of Río Marañón, and describe a new species of Akodon from Huánuco Department, central Peru, a population previously as-signed to A. orophilus.

Evaluación de mamíferos medianos y grandes mediante trampas cámara en un bosque montano del norte del PerúAbstract Camera traps are a powerful tool for inventorying elusive and rare species and very useful to obtain ecological data for plans that involve wildlife conservation. In Peru, several surveys have been carried out in lowland Amazonia especially in the southeastern part of the country, but none in montane cloud forests or Yungas. We present the first camera trap studies produced in Peruvian Yungas at the locality of Querocoto village (Chota, Cajamarca), based on 2002 (dry season) and 1264 (wet season) camera traps-days (CTD). Two localities were surveyed in wet and dry season: The Pagaibamba Protection Forest and the San Lorenzo Forest. The wet season study was carried out in October and November, and the dry season in July to September of 2008. Eight mammalian species were recorded in both seasons. Some 66 (91.7%) independent records were obtained in the dry season, but only six (8.3%) in the wet one, suggesting a seasonality effect. The Mountain Paca Cuniculus taczanowskii was the most commonly photographed species, with 17.0 and 1.6 capture frequencies (dry and wet season respectively), whereas the Long-tailed weasel Mustela frenata (0.5 capture frequency in the dry season) was the most rare species. Activity patterns suggest that Mountain Paca C. taczanowskii and the Andean Skunk C. chinga are nocturnal, while Spectacled Bear T. ornatus and Tayra E. barbara are diurnal in the study area. Our records of the Ocelot Leopardus pardalis and the Tayra E. barbara are among the highest altitudinal records known for each species. In addition, the Anta Tapirus pinchaque was also identified by its tracks, representing one of the first record known south of the Huancabamba Depression. . registraron ocho especies de mamíferos. En la época seca se obtuvo 66 (91,7%) de los eventos independientes mientras en la época húmeda solamente seis eventos (8,3%) sugiriendo un efecto por estacionalidad. La Paca de Montaña (Cuniculus taczanowskii) fue el mamífero más fotografiado con frecuencias de captura de 17,0 y 1,6 para época seca y húmeda respectivamente mientras que Mustela frenata con 0,5 fue la especie más rara registrada solo en la época seca. Los patrones de actividad sugieren que la Paca de Montaña, C. taczanowskii y el Zorrillo Andino, Conepatus chinga son nocturnos, mientras que el Oso de Anteojos, Tremarctos ornatus y la Tayra Eira barbara son diurnos en el área de evaluación. Nuestros registros del Ocelote Leopardus pardalis y la Tayra E. barbara están entre los registros altitudinales más altos conocidos para ambas especies. En adición el Anta Tapirus pinchaque fue identificado por medio de sus huellas y representa su primer registro al sur de la depresión de Huancabamba.Palabras clave: Trampas cámara, inventario, bosques de niebla, Cuniculus taczanowskii, Perú.

The Critically Endangered Peruvian yellow-tailed woolly monkey Lagothrix flavicauda was presumed to only occur in the tropical montane cloud forests between the Marañón and Huallaga rivers in northern Peru. Here we report the discovery of a population to the south of its previously known range, in the Región Junín. During September-December  we carried out transect surveys to record large mammals present near the village of San Antonio in the district of Pampa Hermosa, at ,-, m altitude. We recorded five primate species during transect surveys. Lagothrix flavicauda was seen four times, and appeared phenotypically distinct from populations to the north, with notable white patches above each eye and a reduced yellow patch at the end of the tail. The presence of L. flavicauda in Junín extends its known geographical range over  km southwards from the closest previously known population in the Huánuco region, and presents a unique opportunity for the conservation of this Critically Endangered species.

The Collective Article on "New Mediterranean Biodiversity Records" offers the means to publish biodiversity records in the Mediterranean Sea. The current article presents new biodiversity data information on 18 taxa (14 alien, 3 native and 1 cryptogenic species) belonging to 5 Phyla that are reported for 11 different countries listed according to their geographic position from the western to the eastern Mediterranean Sea. Algeria: the alien green alga Caulerpa taxifolia var. distichophylla and the heterobranchs Aplysia dactylomeda and Aplysia punctata are first reported from the entire country. France: a new record of the alien hydroid Porpita porpita is reported from the Corsican Sea, representing the second record of the species in the western Mediterranean Sea. Tunisia: the alien fish Scatophagus argus is reported from the Gulf of Gabès, probably representing an aquarium release. Italy: the well-established Mediterranean alien bivalve Malleus regula is first reported from the entire country. Slovenia: the alien marine bivalve Xenostrobus securis is reported for the first time from the entire country. Croatia: the alien gastropod Biuve fulvipunctata is reported for the first time from the country but also from the entire Adriatic Sea. Montenegro: the alien bivalve Rapana venosa is reported for the first time from the Montenegrin waters. Albania: the well-established alien fish Lagocephalus sceleratus and the rare native shark Rhizoprionodon acutus are reported for the first from the entire country. Greece: the rare native ray Leucoraja circularis is reported for the first time from the Argolikos Gulf and for the first time for the entire country its identification is confirmed morphologically and molecularly; additional records of the alien nomad jellyfish Rhopilema nomadic document its expanding distribution, while the occurrence and the alien fishes Sillago suezensis and Pomadasys stridens are reported for the first time from Hellenic waters. Turkey: additional records of the Egyptian Prawn Metapenaeopsis aegyptia are reported with some biological information. Cyprus: the alien fish Variola louti is reported for the first time for the entire Mediterranean Sea, probably released from an aquarium, while the alien moon crab Matuta victor is reported for the first time from the entire country.http://epublishing.ekt.gr | e-Publisher: EKT | Downloaded at 16/07/2020 01:30:09 |
