Long‐term change in precipitation and its variability and consequences in a montane environment
Abstract The climate at high altitudes is changing more rapidly than in many other areas, with a variety of consequences for montane flora and fauna. We analyzed long‐term precipitation records from Crested Butte (2703 m, 1910–2025) and Gothic (2921 m, 1974–2026), Colorado, USA, in the West Elk Mountains.

Abstract Plant–animal interactions result in many ecosystem services, such as pollination. In the western hemisphere, and especially the Neotropics, hummingbirds are important pollinators for thousands of plant species, yet there is much to be learned about the spatial and temporal variation in mechanisms influencing these interactions. We collected an

Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

ABSTRACT Understanding the relationships among land degradation, ecosystem functioning and human well‐being is essential for conserving tropical high‐mountain ecosystems. This study examined the relationships among land degradation, Cultural Ecosystem Services (CES), ecosystem disservices (EDS) and visitor perceptions at Laguna Colorados in the Sumapaz

FORMATIVE PERIOD IN THE NORTHERN ANDES AND ITS RELATIONS WITH CENTRAL ANDES
This paper reviews the Ecuadorian Formative (4500-300 ANE) in relationship with its counterpart in the Central Andes (1800-300 ANE), trying to establish the mechanisms that operated processes of cultural transmission and their outcomes, which reflects in the archaeological record (basically ceramics) the level of interaction between these two areas ...

Dispersal‐limited birds at high risk from cattle farming deforestation in tropical forests
Deforestation driven by farming is a major threat to tropical biodiversity. Although this impact is well documented, assessments at local or regional scales often underestimate biodiversity loss at broader national scales by up to 60%. A key question remains: how do farming activities affect functional diversity and species traits across different ...

Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.
