Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador. [PDF]

Ecol Evol
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

Impacts of Species Introductions on the Trait Diversity of Interacting Avian Frugivores and Fleshy‐Fruited Plants Depend on Native Trait Diversity

Global Ecology and Biogeography, Volume 35, Issue 10, October 2026.
ABSTRACT Aim The introduction of non‐native species to native ecological communities by humans is a major driver of global biodiversity change. Studying how species introductions influence interacting species is essential to understanding possible functional consequences of global change because biotic interactions are ecologically crucial.

Systematics and Historical Biogeography of Neotropical Tarantulas: A Genomic Approach to Dolichothele (Araneae: Theraphosidae) Diversification Across Domains

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim The Neotropical region is the most biodiverse in the world, and several hypotheses have been proposed to explain this pattern. Among them, the most prominent are the hypotheses of biotic interchange between domains, climatic refugia during the Pleistocene and geomorphological changes during the Miocene, such as the reorganization of the ...

Muralismo como encargo participativo: Holografía de lo (in)visible en comunidades a’i cofán de la selva colombiana

Anthropology of Consciousness, Volume 37, Issue 2, Fall 2026.
ABSTRACT When mural art in indigenous communities is commissioned as a participatory project, several methodological, epistemological, and aesthetic questions arise. This text proposes a horizontal and investigative approach to what we can simply call ‘muralism in the A'i Cofán community context,’ not as significant works executed in communities, but ...
