In B. hyopro- ra (AMARAL,1935) the maximum litter size known is much lower (13) (CAMPBELL & LAMAR 2004). Accordingly, the mean snout-vent length of newborn B. campbelli (149±8.41 mm) is small in comparison to B. hyoprora (180.7±3.9 mm) and B. microph- thalmus (167.2±8.5 mm) (see CISNEROS- HEREDIA et al. 2006; CAMPBELL & LAMAR 2004).

Methods We updated distribution maps for 41 taxa, using species distribution A Journal of Conservation Biogeography models and a revised presence-records database. We estimated evolutionary dis- tinctiveness (ED) for each taxon using recent molecular and morphological phylogenies and weighted these values with two measures of extinction risk: percentages of habitat loss and IUCN threat status. We mapped phylogenetic diversity and richness levels and compared phylogenetic distances in pitviper subsets selected via endemism, richness, threat, habitat loss, biome type and the presence in biodiversity hotspots to values obtained in randomized assemblages. Results Evolutionary distinctiveness differed according to the phylogeny used, and conservation assessment ranks varied according to the chosen proxy of extinction risk. Two of the three main areas of high phylogenetic diversity were coincident with areas of high species richness. A third area was identified only by one phylogeny and was not a richness hotspot. Faunal assemblages identified by level of endemism, habitat loss, biome type or the presence in biodiversity hotspots captured phylogenetic diversity levels no better than random assem- blages.

CISNEROS-HEREDIA & MARIA OLGA BORJA & DANIEL PROANO & JEAN-MARC TOUZET KURZFASSUNG Spärlich sind die Kenntnisse über Grubenottern der Gattung Bothrocophias. Die vorliegende Arbeit enthält Informationen zu drei Bothrocophias Arten aus Ecuador: Bothrocophias campbelli (FREIRE LASCANO, 1991), B. hyoprora (AMARAL, 1935) und B. microphthalmus (COPE, 1875), einschließlich Angaben zur geographischen und vertikalen Verbreitung, zu Nachweisen in den Provinzen, sympatrischen Grubenotternarten, Aktivitätsmustern, Verhalten, Körpergröße, Fortpflanzungsbiologie, Nahrung und Lebensalter. Bothrocophias campbelli bewohnt die nördlichen, zentralen und südlichen Gebiete der pazifischen Andenabhänge Ecuadors zwischen 800 und 2000 m; Bothrocophias hyoprora kommt im nördlichen und südlichen Amazonastiefland und an den unteren östlichen Hän- gen der Anden Ecuadors zwischen 210 und 1500 m vor, Bothrocophias microphthalmus an deren Südosthängen zwischen 600 und 2350 m. Die Arbeit berichtet über den zweiten Fundortnachweis von B. campbelli in der Provinz Imbabura und den westlichsten Fundort von B. hyoprora im Tal des Nangaritza Flusses. Das ympatrische Vorkom- men von B. hyoprora und B. microphthalmus im Makuma-Gebiet, Provinz Morona-Santiago, wird bestätigt, was die bisher bekannte obere Verbreitungsgrenze von B. microphthalmus auf zumindest 600 m anhebt. Das Weiß- bauch-Mausopossum Marmosops noctivagus wird erstmals als Beutetier von B. microphthalmus beschrieben. Die neuen Daten über die Fortpflanzungsbiologie von Grubenottern der Gattung Bothrocophias umfassen Wurfgröße und Körperlänge Neugeborener bei B.

School and University Center, The City Location United States, North America. University of New York, 365 Fifth Avenue, New York, NY 10016, USA Methods Using total length and mass, we examine body size frequency distribu- tions (BSFD) across 79 sites and respective biomes to determine if these areas represent random subsamples from the source pools of taxon body sizes. Using QuaSSE, we determine if the most probable model of trait-driven diversification in the three most common groups of snakes in North America, the ratsnakes, pitvipers and watersnakes, is similar to the predicted regional BSFD. Results BSFD of snakes at the community, biome, regional and clade scales show symmetric distributions of body size. These patterns may simply be generated from random statistical subsampling. Speciation rates are not highest at or near the modal body size and simulations show that linear trait-driven models can still yield highly symmetric distributions of body size. Main conclusions In this study region, processes such as competition due to size do not alter BSFD from one scale to the other.

This richness is represented by 35 species of turtles, fve crocodilians, and 437 squamates including three amphisbaenians, 197 lizards, and 237 snakes. Of these, 45 species are endemic to the Galápagos Islands and 111 are mainland endemics. The high rate of species descriptions during recent decades, along with frequent taxonomic changes, has prevented printed checklists and books from maintaining a reasonably updated record of the species of reptiles from Ecuador. Here we present Reptiles del Ecuador (http://bioweb.bio/faunaweb/reptiliaweb), a free, resource-rich online portal with updated information on Ecuadorian reptiles. This interactive portal includes encyclopedic information on all species, multimedia presentations, distribution maps, habitat suitability models, and dynamic PDF guides. We also include an updated checklist with information on distribution, endemism, and conservation status, as well as a photographic guide to the reptiles from Ecuador.
