Mitochondrial Markers COI and 16S rRNA for the Molecular Identification of Parrots and Macaws Recovered From Illegal Trafficking in Three Areas of Colombia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We molecularly characterized parrots (Amazona spp.) and macaws (Ara spp.) rescued from illegal trafficking in Colombia using two mitochondrial markers (COI and 16S rRNA). The COI gene showed high resolution for species identification and revealed considerable intraspecific diversity, while 16S rRNA displayed limited taxonomic resolution.

Habitat Protection Alone Is Insufficient: Costa Rican Parrots Thrive in Altered Landscapes but Remain Vulnerable to Poaching

Diversity and Distributions, Volume 31, Issue 9, September 2025.
ABSTRACT Aim Human population growth and resource overexploitation have induced major changes in global biodiversity. Costa Rica, with 26% of its land area protected, is often cited as a model of environmental conservation. However, conservation efforts have largely focused on habitat preservation, while overharvesting remains an unquantified factor in

The role of biogeographical barriers on the historical dynamics of passerine birds with a circum‐Amazonian distribution

Ecology and Evolution, Volume 14, Issue 3, March 2024.
This study found similarities at populational, phylogenetic, and evolutionary levels among four taxonomic groups of passerine birds with a circum‐Amazonian distribution. The presence of Refugia result of climatic oscillations during the Pleistocene was the main drive in the diversification of these circum‐Amazonian taxa.

Variable shifts in bird and bat assemblages as a result of reduced‐impact logging revealed after 10 years

Journal of Applied Ecology, Volume 61, Issue 1, Page 145-159, January 2024.
Our study demonstrates how best practice forestry and logging can maintain healthy vertebrate populations over the long term. Forestry concessions that adopt techniques of low‐harvest RIL and are managed for their long‐term timber provision through extension of regeneration times beyond 10 years after harvest, are likely to benefit from the ecosystem ...
