Abstract 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.

Abstract Fundamental axes of variation in plant traits result from trade-offs between costs and benefits of resource-use strategies at the leaf scale. However, it is unclear whether similar trade-offs propagate to the ecosystem level. Here, we test w

Effective Hamiltonian for Stokes--anti-Stokes pair generation with pump and probe polarized modes

Autor: Diaz, R. Acosta, Monken, C. H., Jorio, A., Santos, Marcelo F.

Publikováno v: Phys. Rev. B 102, 134304 (2020)

In the correlated Stokes--anti-Stokes scattering (SAS) an incident photon interacts with a Raman-active material, creating a Stokes photon and exciting a quantum vibrational mode in the medium, which is posteriorly annihilated on contact with a secon

DISCOVERY OF OSCAECILIA POLYZONA (AMPHIBIA: GYMNOPHIONA: CAECILIAIDAE) IN THE MIDDLE MAGDALENA WITH NOTES ON ITS ABUNDANCE AND HABITAT

Autor: John D. Lynch, Andrés R. Acosta

Publikováno v: Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, Vol 28, Iss 109 (2023)

Se registra Oscaecilia polyzona en dos localidades en el valle medio del río Magdalena; los datos obtenidos de 13 especímenes indican que la especie es abundante, hallándose principalmente en suelos mal drenados. Por otra parte, ponemos en duda el
