ARTICLE Ongoing harlequin toad declines suggest the amphibian extinction crisis is still an emergency Biodiversity loss is extreme in amphibians. Despite ongoing conservation action, it is difficult to determine where we stand in overcoming their extinction crisis. Among the most threatened amphibians are the 131 Neotropical harlequin toads. Many o...
This preprint is to try understand evolutionary basis of life diversification. It looks to solve macroevolutionary dilemmas
Anthropogenic biodiversity loss is extreme in amphibians. Despite ongoing conservation action, it is difficult to determine where we stand in overcoming their extinction crisis 1,2. Extinction risk is not equally distributed across amphibians 3-5. Among the most threatened amphibians are the 131 Neotropical harlequin toads (Atelopus), many of which...
I report the first encounter in Central America of an individual of Caecilia guntheri Dunn, 1942 (Gymnophiona, Caeciliidae). The individual was observed and collected in a primary evergreen submontane forest in Cerro Pirre, Darien Province, Republic of Panama. It was identified mainly by the low counts of secondary and primary folds. The encounter...
Despite historical interest in brain size evolution in vertebrates, few studies have assessed variation in brain size in squamate reptiles such as snakes and lizards. Here, we analyzed the pattern of brain allometry at macroevolutionary scale in snakes and lizards, using body mass and snout vent length as measures of body size. We also assessed pot...
Resumen Describimos la comunidad de reptiles escamosos registrados durante muestreos diurnos y nocturnos en el bosque submontano de la localidad de Cerro Bruja, provincia de Colón. Estos muestreos forman parte de un programa de monitoreo de anfibios, pero cuya oportunidad para detectar reptiles fue muy útil. Cerro Bruja está dentro de los límites d...
Se presentan datos sobre la composición de comunidades de anfibios y reptiles en
localidades del Parque Nacional Santa Fé (PNSF) y del Parque Nacional General de
División Omar Torrijos Herrera (PNGDOTH). Ambas áreas protegidas fueron
impactadas respectivamente en el año 2002 y 2004 por la quitridiomicosis, una
enfermedad exclusiva para los anfibios...
We describe an apparent predation event on a young Basiliscus basiliscus (Sauria: Corytophanidae) by the scorpion Opisthacantus elatus (Scorpiones: Hemiscorpiidae). The scorpion was 2 m aboveground and hiden inside an interstice of a fallen branch. The pedipalps of the scorpion were outside of the branch and with these weapons the scorpion was hold...
Amphibians around the world are declining from threats that cannot currently be mitigated, making it impossible to safeguard some species in their natural habitats. Amphibians in the mountainous neotropics are one example where severe disease-related declines prompted calls for the establishment of captive assurance colonies to avoid extinctions. W...
The fossorial snake Geophis bellus is a small Panamanian endemic previously known only from the holotype. Here we report additional specimens, which greatly expand the known range of the species ca. 200 km from the type locality into western Panama. Furthermore, we provide information on sexual dimorphism in some scalation counts and in body and ta...
Males of Leptodactylus savagei in an event of sexual explosion are displaying soft calls of lower volume and shorter duration than the usual “whuup” of its advertisement call. The soft calls were displayed between amplectant males and satellite males in a very short distance. After soft calls displaying some amplectant males move away from the coup...
La evaluación específica de la biodiversidad es esencial para minimizar los riesgos de error en la aplicación de medidas para conservación. Más allá de la riqueza de especies, la medición de componentes estructurales como dominancia y equitatividad distribucional de individuos, brinda una mejor comprensión de aspectos ecológicos que no son percibid...
Artículo de Opinión Publicado el 30 de agosto de 2014 https://www.laestrella.com.pa/opinion/columnistas/140830/electrica-interconexion ¿Cómo la inversión anual en importación, y transmisión, será recuperada por ETESA y el gobierno nacional? La relación actual entre el desarrollo nacional y la demanda de energía eléctrica es preocupante por nuestro...
Luego de las declinaciones de anfibios algunas especies persisten en el escenario del proceso ecosistémico. Los anfibios son parte de la dieta de algunos reptiles como las serpientes, y compiten con las lagartijas por presas de invertebrados. Por consiguiente, entender la estructura ecológica de las comunidades perturbadas de anfibios, y los reptil...
El conocimiento y análisis de la biodiversidad es una de las mejores herramientas con que cuentan los gobiernos para tomar decisiones adecuadas para la conservación en áreas protegidas. Con el incremento de las amenazas a las áreas protegidas, igual se incrementaron los esfuerzos por conocer y conservar los componentes biológicos de áreas protegida...
Ants have great size diversity and are one of the most dominant insect groups in the world. Within the leaf-cutting ants of the neotropics, the genus Atta exhibits a large degree of physical polymorphism, with workers ranging in size from only a few millimeters in length to over two centimeters. We used this size diversity in Atta colombica to stud...
RESUMEN Se presentan los resultados del primer inventario sobre la riqueza de especies y estado de conservación para saurios y serpientes en la Reserva Forestal La Tronosa, (RFT). Basados en colectas y observaciones en el área, se confirmó la presencia de 32 especies de reptiles correspondientes a 25 géneros distribuidos en 10 familias. Del total d...

Dormancy is a physiological trait with convergence between many orders of insects and mammals. Insects are protostomes and mammals deuterostomes, the two big groups which bilateria has been systematically divided. Exploring dormancy genes in fossil material of extinct bilaterians should change the evolutionary process of dormancy as we know actually. This because the wide range of diversity of ancestral bilaterians occur mainly in the sea and in the benthic substrate of the sea. With this in consideration some ancestral bilaterians could bury themselves in the sand or be hidden in rocks or cave in the deep sea for dormancy. If dormancy occur in the past there should be something like homology or paralellism in the evolution of dormancy between protostomes and deuterostomes.
Good days to all the comunity. I'm doing works on trait evolution at interspecific level and I'm having problems with philogenetic tests. I need some easy tutorials for phylogenetic regressions and correlations on R program. Consider that I'm a roockie using R program. However, I think that despite everything is possible to get the skill. Very thank for some help.
