Aims Pastoralism is a land‐use system that involves the care and use of grazing livestock and has been more common in areas of low resource availability. In this review, we analyze the impact of pastoralism on biodiversity and ecosystem services across the tropical Andes. This region is the most extensive and populated tropical mountain region in t...

Aim Climate change is transforming mountain summit plant communities worldwide, but we know little about such changes in the High Andes. Understanding large‐scale patterns of vegetation changes across the Andes, and the factors driving these changes, is fundamental to predicting the effects of global warming. We assessed trends in vegetation cover,...

El páramo ecuatoriano constituye un bioma complejo y heterogéneo cuya composición y estructura varían ampliamente a lo largo de los gradientes de elevación, clima, sustrato geológico e historia biogeográfica. Desde el punto de vista de su ecología y conservación, este bioma ha sido caracterizado principalmente como un ecosistema abierto dominado po...

Humans are intertwined with the environment, and the consequences are profound for biological diversity, and fundamental for planning conservation strategies and goals. The likely formal recognition of the Anthropocene Epoch allows for new approaches to measuring biodiversity, and for clarifying human roles in altering patterns and processes. Many...

Due to warming, changes in microclimatic temperatures have shifted plant community structure and dynamics in tundra and alpine regions. The directionality and magnitude of these changes are less known for tropical alpine ecosystems. To understand the likely trajectory of these shifts in the Andes, we conducted a warming experiment in the northern A...

Although species have always shifted their ranges, the rapid pace of current biophysical changes and the further complications imparted by human land use provide unprecedented challenges for biodiversity conservation. As a result, goals, methods, and strategies are being reconceptualized. For example, the terms conservation and wilderness protectio...

In this study, we evaluate the effectiveness of indicators for rehabilitation practices in high mountain landscapes that were aimed at increasing grassland palatability and biomass accumulation. Focusing on the department of Huancavelica in Peru, the importance of rehabilitation practiced in this area involves the relationship of alpaca pastoralist...

The Kruzof and Baranof Islands Integrated Natural Resource Management Assessment evaluates and offers recommendations for current management initiatives while identifying strategies for future management, restoration, and outreach plans for the U.S. Forest Service Sitka Ranger District. The project report is divided into three main focus areas: Com...
