Two years ago we reported on the discovery of two new species of terrestrial breeding frogs, Pristimantis antisuyu and P. erythroinguinis from Manu National Park in Cusco and Madre de Dios, in the Amazonian Andes and foothills. This month we add another closely related species, also with cruciform eyes, from another protected area: El Sira Communal Reserve. The description, led by our collaborator Germán Chávez, was published in the last issue of the online journal Evolutionary Systematics. 

The name of the new species, Pristimantis sira, honors the protected area. Although P. sira shares several morphological characteristics with P. antisuyu, P. cruciocularis, and P. erythroinguinis, it can easily be distinguished by the lack of inguinal spots, which vary from yellow to red in the other species. We observed P. sira  on leaves, at 1–1.7 m height, in the forests of the eastern slopes of the mountains of El Sira Communal Reserve, from 1500 to 2200 m a.s.l.The habitat at 1500 m a.s.l. is a montane forest, with riparian vegetation consisting mainly of bushes, tree ferns and trees with a canopy ~20 m tall (see pics below).

El Sira Communal Reserve is located on the eastern slopes of the Andes in central Peru, and protects about 616 thousand hectares of primary forest. El Sira is the highest cordillera adjacent to the Ucayali River, going from 200 m to 2200 m a.s.l., and is bordered by the Pachitea river (which eventually flows into the Ucayali), further isolating the El Sira mountains as the eastern branch of the Andes in the Ucayali basin. Because of the difficult access and rough topography, El Sira is likely one of the most unexplored places of Peru, and likely to harbor additional species waiting to be discovered and named.

Earlier this morning, lab member and PhD student Anne Sabol passed her quals - congratulations Anne! 

Marsupial frogs are fairly diverse in the Andes, with over 75 species of Gastrotheca, and there are many cryptic species yet to be discovered. Our lab contribution, in collaboration to leading author Pablo Venegas, led to the discovery of a new species from the Cordillera de Colán in northern Peru. The new species, named Gastrotheca gemma lives in the páramo and the ecotone between páramo and humid montane forest of Cordillera de Colán, at elevations around 3100-3200 m.

Lab member and PhD student Rachel Prokopius passed her qualifying exams today. She had completed her written exams earlier in March. Congrats Rachel!

Along with collaborators Edgar Lehr and Shenyu Lyu, we described a new species of terrestrial-breeding frog from the region of Cajamarca in northern Peru. Pristimantis astralos is only known from its type locality at 3600 m a.s.l. in the Cordillera Occidental. Mining operations, and especially large-scale dumping of mining debris at the type locality over the last decade, have destroyed the type locality and caused the extirpation of the population at the type locality (see Google Earth pic below). 

Peru has a thriving mining industry, and is a major producer of metals including copper, gold and zinc. This industry generates important economic benefits but can also cause environmental degradation and biodiversity loss at scales from local to regional.  High-elevation tropical ecosystems are rich in endemic species, and thus even localized habitat destruction could contribute to species extinction. To prevent extinctions, we need better information concerning the distribution of endemic species, which requires surveys in the field by knowledgeable herpetologists.

PhD student Anne Sabol co-authored a paper on personality of wild mice (Peromyscus), published this month in Behavioral Ecology and Sociobiology along with her former colleagues from the University of Michigan (where she obtained her Master's degree). This work was a multiyear effort with two species (Peromyscus leucopus noveboracensis and Peromyscus maniculatus gracilis).

The results show that the two species of wild mice exhibit personalities and that their personality traits are associated with one another, in that mice that were less docile were also more active, exploratory, and bold. The mice's personality traits were not linked with body mass, suggesting a lack of association between internal state and personality.

Congratulations Anne!!

The special issue Systematics and Conservation of Neotropical Amphibians and Reptiles is now closed, all submitted papers have been published. The final tally is 14 papers, covering frogs, salamanders, caecilians, lizards, and snakes from throughout the Neotropics, with specific studies from Mexico, Costa Rica, Panama, Colombia, Ecuador, Peru, Paraguay and Brazil. Authors in this special issue named a new genus of frogs (Qosqophryne), four new species of frogs (one terrestrial-breeding frog and three glassfrogs) and five new lizards (three tropidurid and two gymhnophthalmid lizards). A monograph on glassfrogs of Ecuador span the three thematic areas. Among contributions on biogeography, approaches ranged from species distribution patterns to the use of barcoding at the country level, phylogenomic analyses using ultra-conserved elements, and island biology. The remaining studies examined current conservation issues, examining the impact of mining, fungal disease, and the conservation implications of endemism.

Alex's defense on 23 October. Congratulations Alex!

Alex Shepack will be defending his dissertation on October 23rd. His dissertation, "Back from the Brink: Rebounding and Remnant Amphibian Populations in a Pathogen Enzootic Environment," examines the long-term impacts of the amphibian chytrid fungus (Batrachochytrium dendrobatidis) on Neotropical amphibians. Research in Peru yielded insights on how a single species can dominate the transmission of Bd in the environment, and potentially shape the rest of the amphibian community. Work conducted across Costa Rica helped characterize the demography and structure of a recovering population and examined the changes in genetic structure that arise from declines and recoveries. If you're interested in learning about these projects (and more!), please contact us. We'd love for you to join (via Zoom) on October 23rd at 2P.M. EST!
