Alloparental care in glassfrogs: males care for unrelated clutches only when as...
Valencia-Aguilar, Anyelet [UNESP]; Guayasamin, Juan M.; Prado, Cynthia P. A. [UNESP]Made available in DSpace on 2021-06-25T12:40:13Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-14; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Parental care is costly, thus theory predicts that parents should avoid caring for unrelated offspring. However, alloparenting has been reported in many taxa because it may increase the caregiver mating success or offspring survival. We expe...
Validating anthropogenic threat maps as a tool for assessing river ecological i...
Lessmann, Janeth; Troya, Maria J.; Flecker, Alexander S; Funk, W Chris; Guayasamin, Juan M.; Ochoa-Herrera, Valeria; Poff, N LeRoy; Suarez, EstebánAnthropogenic threat maps are commonly used as a surrogate for the ecological integrity of rivers in freshwater conservation, but a clearer understanding of their relationships is required to develop proper management plans at large scales. Here, we developed and validated empirical models that link the ecological integrity of rivers to threat maps in a large, heterogeneous and biodiverse Andean-Amazon watershe...
Freshwater vertebrate and invertebrate diversity patterns in an Andean-Amazon b...
Lessmann, Janeth; Guayasamin, Juan M.; Casner, Kayce L.; Flecker, Alexander S.; Funk, W. Chris; Ghalambor, Cameron K.; Gill, Brian A.The Napo Basin in Ecuador is an important drainage of the Amazon Basin, the most biodiverse ecosystem for freshwater species. At the same time, this basin has conspicuous information gaps on its biodiversity patterns and human threats. Here, we estimated the diversity distribution patterns of freshwater vertebrates and invertebrates in the Napo Basin, as a tool for present and future management and conservation...

Notes on the taxonomy of some Glassfrogs from the Andes of Peru and Ecuador (Am...
Cisneros-Heredia, Diego F.; Guayasamin, Juan M.We present new information on several species of centrolenid frogs from Ecuador and Peru that justify the placement of Centrolene fernandoi Duellman and Schulte as a junior synonym of Centrolenella audax Lynch and Duellman; Centrolenella puyoensis Flores & McDiarmid as a synonym of Centrolenella mariae Duellman & Toft; and Cochranella tangarana Duellman & Schulte as a synonym of Cochranella saxiscandens Duellma...
Distribution, vocalization and taxonomic status of hypsiboas roraima and h. ang...
Barrio-Amorós, César L.; Señaris, Josefa Celsa; Macculloch, Ross D.; Lathrop, Amy; Guayasamin, Juan M.; Duellman, William E.The distribution of the poorly known hylid frog Hypsiboas roraima Duellman & Hoogmoed, on the Guiana Shield is redefined, including new records from Venezuela. The advertisement call of this species is analyzed and Hypsiboas angelicus Myers & Donnelly is associated as a junior synonym of H. roraima.; Redefinimos la distribución del hílido guayanés Hypsiboas roraima Duellman & Hoogmoed. Analizamos su canto y con...
Una nueva especie de sapo del género Osornophryne (Anura: Bufonidae) de las est...
Mueses-Cisneros, Jonh Jairo; Yánez-Muñoz, Mario Humberto; Guayasamin, Juan M.Se describe una nueva y llamativa especie de Osornophryne de las estribaciones orientales de los Andes norte de Ecuador, Provincia de Sucumbíos, entre los 2.600 y 2.800 m. La nueva especie se distingue de la mayoría de sus congéneres (excepto de O. guacamayo) por presentar los dedos pediales IV y V alargados, probablemente como una adaptación a hábitos arbóreos. Osornophryne cofanorum sp. nov. difiere de todos ...
Redescripción de Cochranella megista (Rivero, 1985) y ampliación de la distribu...
Rada, Marco; Guayasamin, Juan M.In 1980, Marco Antonio Serna collected two individuals of an unusual glassfrog from Departamento de Antioquia, Colombia. These specimens exhibit some peculiar characteristics, including a large body size. It seems that only one of these specimens was sent to Juan A. Rivero for its identification; Rivero (1985) described the species under the name of Centrolenella megistra. Herein, we redescribe and designate a ...
