Terry Erwin’s race to document arthropod diversity inspired taxonomists, systematists, ecologists, evolutionary biologists, and the conservation community at large, as his curatorial work of more than 50 years at the Smithsonian’s National Museum of Natural History and prolific publication record attests. The biography compiles public records, publ...

Bofedales are Andean wetlands associated with glacial moraines in which water is retained due to the presence of vegetation growing in a cushion-like form. Peat accumulated through time functions as water reservoirs and carbon sinks, that constitute important hot spots for plant and animal species. Currently, the development of linear infrastructur...

We document chigger mite (Acari: Trombiculidae) ectoparasitic infestation (prevalence and intensity) on a population of Catharus ustulatus (Turdidae) wintering at a site in southeastern Peru undergoing development for natural gas exploration (PAD A). We compare prevalence (i.e., the proportion of individuals infested by chigger mites) and intensity...

We assessed area and habitat heterogeneity effects on avian richness and composition in bofedales that differed in size and microhabitat diversity. We analyzed data collected in 2 seasons and 24 bofedales using General Linear Models, Ordinary Least Square models to establish the relationship of predictor variables on richness and Akaike Information...

PERU LNG designed and constructed a trans-Andean gas pipeline and liquefied natural gas (LNG) plant and marine terminal and is in charge of its operation. A biodiversity monitoring and assessment program (BMAP) was developed and implemented as part of the company's biodiversity action plan. In this paper we provide the strengths and challenges of d...

The IXth NOC celebrated in Cusco, Peru, was dedicated to Maria Koepcke, ornithologist that contribute greatly to the knowledge of Neotropical birds and the study of Peruvian birds. For this homage, we compiled a complete list of the publications of M. Koepcke, many of which were published as coauthor with her husband, the ecologist Wilhelm Koepcke

The IXth Neotropical Ornithological Congress in Peru (Cusco, 8 – 14 November 2011). -The IXth Neotropical Congress of Ornithology (IX NOC), co-sponsored by the Neotropical Ornithological Society (NOS) and the Union of Peruvian Ornithologists (UNOP), took place in Cusco, Peru, from the 8 – 14 November 2011. The IX NOC was dedicated to the memory of...

Extendemos el rango migratorio, altitudinal y de distribución norte de Muscisaxicola frontalis (“Dormilona de Frente Negra”), migrante Austral previamente reportado para el sur del país. La especie fue observada en laderas pedregosas cerca a remanentes de bosque de Queñoa (Polylepis flavipilla, Rosaceae) a 4450 m de altitud, en el Departamento de H...

Presentamos un listado de 159 especies de aves de la Reserva Nacional de Salinas y Aguada Blanca (RNSAB), basado en la recopilación de literatura y nueva evidencia obtenida por los autores hasta la fecha. En términos de abundancia, se reportan 14 especies de aves abundantes, 32 comunes, 39 frecuentes, 32 escasas y 37 especies raras. Asimismo, nuest...

We extent the distribution range in Peru of Asthenes sclateri, Cabanis ("Puna Canastero"), a species reported only for the Puno Department. The observations of many individuals of the species (documented with pictures and specimens) were made in high Andean pastures nearby Polylepis woodlands in the Arequipa Department.

We describe a distinctive new species of twistwing (Tyrannidae: Cnipodectes) from southeastern Peru. Despite extensive ornithological research in the region, this species has escaped notice, which suggests that it may be restricted to larger blocks of forest dominated by bamboo (Guadua spp.), a habitat poorly sur-veyed in Amazonia. Currently known...

Understanding the extent to which patterns of functional structure and organization are repeated in space and time and the level or scale at which different factors (local and regional) operate to explain community patterns are of central importance in studies of community ecology. In this dissertation, I studied the extent of spatial variation in...

Los bosques de Polylepis (“queñual”) de la Cordillera del Vilcanota (3600-4500m) son ecosistemas que contienen una fauna y flora única, caracterizada por especialistas de hábitat y altos niveles de endemismo. Desdichadamente, éstos bosques también representan uno de los hábitats más vulnerables de los altos Andes por la fuerte presión antropogénica...

Includes the results of the rapid assessment of birds in the Vilcabamba Mountains of Peru

A review of the composition of five montane avifaunas in northwestern South America and southern Central America confirmed the distinctness of these communities from adjacent lowland areas. Excluding species that depend on aquatic resources, 1,800 bird species from 52 families were classified according to principal life zones in this review. There...
