AbstractEnvironmental limits of animal life are invariably revised upwards when the animals themselves are investigated in their natural habitats. Here we report results of a scientific mountaineering expedition to survey the high-altitude rodent fauna of Volcán Llullaillaco in the Puna de Atacama of northern Chile, an effort motivated by video documentation of mice (genus Phyllotis) at a record altitude of 6205 m. Among numerous trapping records at altitudes >5000 m, we captured a specimen of the yellow-rumped leaf-eared mouse (Phyllotis xanthopygus rupestris) on the very summit of Llullaillaco at 6739 m. This summit specimen represents an altitudinal world record for mammals, far surpassing all specimen-based records from the Himalayas and elsewhere in the Andes. This discovery suggests that we may have generally underestimated the altitudinal range limits and physiological tolerances of small mammals simply because the world’s highest summits remain relatively unexplored by biologists.

Solanum medians is a widely distributed species of wild potato (Solanum sect. Petota), growing along the coastal lomas and up the western slopes of the Andes Mountains from central Peru and northern Chile, from 200–3800 m elevation. Fertile diploid and sterile triploid cytotypes are common, are believed to be associated with morphological variants, and are formally named as subspecies. A morphometric study based on principal components and canonical discriminate analyses of characters obtained from herbarium specimens tests the circumscription of these subspecies and other currently recognized species that are very similar to S. medians. The results show so much overlap of these taxa that it is impractical to use morphology to define species or to provide reliable keys or identifications. We synonymize ten names under S. medians: S. medians var. angustifoliolum, S. medians var. majorifrons subvar. majorifrons, S. medians var. majorifrons subvar. protohypoleucum, S. medians var. autumnale, S. sandemannii, S. tacnaense, S. weberbaueri var. decurrentialatum, S. tacnaense f. decurrentialatum, S. weberbaueri, S. weberbaueri var. poscoanum. We also treat S. neoweberbaueri as a closely related species to S. medians. We consider the synonymy in S. medians to be part of a much larger need for reduction of names in sect. Petota.

The present study is a review of the main inland water malacostracan species of northern Chile: Cryphiops caementarius (Molina, 1782). This species sustains the local fisheries in northern and central Chilean hydrographical basins. Cryphiops caementarius, in Chile known as the northern river shrimp, is endemic to rivers west of the Andes Mountains in Peru, and south from Chancay-Lambayeque River and the rivers in the northern Chilean littoral up to 32°55′S. Research on this species in its natural habitat consigned between 1958 to 2008 was directed to population knowledge, including mainly the existing populations in rivers in the Regions of Atacama and Coquimbo. Important advances were also made with regards to the study of the embryonic development, biology, life cycle and reproduction that serve as a basis for the technological development of juvenile production in a controlled environment.
