How Earth Remote Sensing From The International Space Station Complements Current Satellite‐Based Sensors, Jennifer Gebelein, Dean Eppler Jul 2006

How Earth Remote Sensing From The International Space Station Complements Current Satellite‐Based Sensors, Jennifer Gebelein, Dean Eppler

Jennifer Gebelein

The International Space Station (ISS) will provide an Earth‐and space‐observing platform that will support sensors built by 16 different countries and deliver data and images for local, regional and global research. When complete, it will be an exceptional platform for conducting remote sensing of the Earth, astrophysics, and space physics research programmes. Additionally, the ISS will operate as a testbed for engineering studies and complex technological developments that will benefit future Earth‐observing capabilities. ...


The Scent Of Danger: Tetrodotoxin (Ttx) As An Olfactory Cue Of Predation Risk, Richard Zimmer, Daniel Schar, Ryan Ferrer, Patrick Krug, Lee Kats, William Michel Dec 2005

The Scent Of Danger: Tetrodotoxin (Ttx) As An Olfactory Cue Of Predation Risk, Richard Zimmer, Daniel Schar, Ryan Ferrer, Patrick Krug, Lee Kats, William Michel

Lee Kats

Larvae of the California newt (Taricha torosa) exhibit striking predator- avoidance behavior, escaping to refuges in response to a chemical cue from cannibalistic adults. In laboratory flow-tank experiments, stream water collected near free-ranging adults induced hiding responses in 100% of the larvae tested. Solutions prepared by bathing adults (in field and laboratory) also evoked strong hiding behaviors. Insensitive to adult feeding status (fed or starved), and clearly not an excretory product, the chemical cue was released from adult skin (i.e., in swabs of adult backs, sides, and bellies). Tetrodotoxin (TTX) was found in skin swabs of adults and in bathwater …

A New Species Of Eleutherocadtylus (Anura: Leptodactylidae) From The Eastern Andes Of Central Peru With Comments On Central Peruvian Eleutherodactylus, Edgar Lehr, Mikael Lundberg, Cesar Aguilar, Rudolf Von May Dec 2005

A New Species Of Eleutherocadtylus (Anura: Leptodactylidae) From The Eastern Andes Of Central Peru With Comments On Central Peruvian Eleutherodactylus, Edgar Lehr, Mikael Lundberg, Cesar Aguilar, Rudolf Von May

Edgar Lehr

A new species of the Eleutherodactylus nigrovittatus Group is described from five localities, at elevations of 1800-2760 m in cloud forests in the Cordillera Oriental in central Peru (Distrito de Paucartambo, Departamento de Pasco). The new species is assigned to the Eleutherodactylus nigrovittatus Group, and differs from all described species therein by having a combination of smooth skin on the venter, undilated discs on the digits, Finger I and Finger II of variable length (slightly shorter, slightly longer or of equal length), Toe III and Toe V of variable length (slightly shorter, slightly longer or of equal length), and a …


A New Species Of Glass Frog (Centrolenidae: Cochranella Ocellata Group) From Central Peru, Edgar Lehr, Juan Guayasamin, Daniel Rodriguez, Cesar Aguilar Dec 2005

A New Species Of Glass Frog (Centrolenidae: Cochranella Ocellata Group) From Central Peru, Edgar Lehr, Juan Guayasamin, Daniel Rodriguez, Cesar Aguilar

Edgar Lehr

We describe a new species of Cochranella from the Cordillera de Carpish, Departmento Huánuco, Peru. The new species is placed in the Cochranella ocellata group and can be distinguished from all other species of Cochranella by having: (1) small white and dark purple spots on the dorsum; (2) a snout slightly protruding to truncate in lateral aspect; (3) and basal webbing between Fingers III and IV.


Taxomic Status Of Some Species Of Peruvian Phrynopus (Anura: Leptodactylidae), With The Description Of A New Species From The Andes Of Southern Peru, Edgar Lehr Dec 2005

Taxomic Status Of Some Species Of Peruvian Phrynopus (Anura: Leptodactylidae), With The Description Of A New Species From The Andes Of Southern Peru, Edgar Lehr

Edgar Lehr

Based on external morphological and osteological characters, Phrynopus fallaciosus and Phrynopus flavomaculatus are placed in the Eleutherodactylus nigrovittatus Group, and the latter is reported for the first time in Peru (Departmento de Piura). Based on external morphological characters, Phrynopus laplacai is considered to be a junior synonym of P. wettsteini. The type locality of P. wettsteini in Peru is considered as doubtful, and the distribution of the species seems to be restricted to Bolivia. Based on external and internal morphological characters, including comparatively large testes, Phrynopus spectabilis is placed in the synonymy of Pleurodema marmorata. Males of several species of …


A New Species Of Marsupial Frog (Anura: Hylidae:Gastrotheca) From The Amazonian Slopes Of The Cordillera Oriental In Peru, Edgar Lehr, William Duellman, Linda Trueb Dec 2005

A New Species Of Marsupial Frog (Anura: Hylidae:Gastrotheca) From The Amazonian Slopes Of The Cordillera Oriental In Peru, Edgar Lehr, William Duellman, Linda Trueb

Edgar Lehr

A New species of marsupial frog, Gastrotheca, with prominent cranial crests is described from humid montane forest on the eastern slopes of the Andes in Departmento de Pasco, Peru. The frog ahs an exceedingly robust cranium that most closely resembles that of G. cornuta; however, the cranial crests of G. cornuta are less well developed, and less obvious externally, than those of the new taxon. Within the genus Gastrotheca, one of the most variable parts of the skull is the squamosal, which has a variety of articular arrangements with the maxilla, the pterygoid, and in some taxa, the frontoparietal. In …
