The Andean Altiplano, characterized by its extreme climatic conditions and high levels of biodiversity, provides a unique environment for studying ecological and evolutionary adaptations in insect morphology. Butterflies, due their large wing surface compared to body surface, and wide distribution among a geographical area given the flight capabilities provided by their wings, constitute a good biological model to study morphological adaptations following extreme weathers. This study focuses on , a butterfly species widely distributed in the Andes, to evaluate wing shape variation across six localities in the Northern Chilean Altiplano.

- Desert aquatic species often have separated populations because of their fragmented environments, but geography and humidity can aid their movement.
- This study examined how the shape of river drainage systems affects the genetic diversity and movement of a specific frog species in the Atacama Desert.
- Findings revealed three genetic clusters based on river basins, indicating that populations within the same drainage have more gene flow between them, suggesting that the river structure and regional humidity impact their genetic relationships.
Article Synopsis
- Telmatobius is the most diverse group of frogs in the Andean highlands, with a complicated taxonomy due to large variations within species.
- The study focuses on T. marmoratus, which has a broad distribution but is not fully understood, aiming to clarify its species complexities using DNA analysis techniques.
- Results indicate the presence of 7 distinct lineages and 6-10 potential new species within the marmoratus complex, revealing a complex evolutionary history related to ancient water connections in the region.
Island ecosystems differ in several elements from mainland ecosystems and may induce variations related to natural selection and patterns of adaptation in most aspects of the biology of an organism. (Waterhouse, 1839) is a marsupial endemic to Chile, distributed from Loa River to Concepción. Historically, three subspecies have been described: , and .
