Land Degradation &Development, EarlyView.ABSTRACT Soil disturbance resulting from forest harvesting activities can have significant and lasting environmental consequences, particularly in sensitive ecosystems such as Mediterranean forests. Skid trails, the routes used by machinery to extract timber, are among the most critical areas of impact, and their detection is critical for assessing ...

Mixing regimes in tropical high‐mountain Andean lakes
Limnology and Oceanography, EarlyView.Abstract Lowland tropical lakes deeper than 15 m are typically warm monomictic, but whether the regime may switch to polymixis at high elevations remains uncertain. Using a year‐long high‐frequency dataset from thermistor chains from 10 deep lakes and occasional temperature profiles from 202 lakes in Ecuador's Cajas Massif, this study examines the ...

Limnology and Oceanography, EarlyView.Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

GEOUSP: Espaço e Tempo (Online), 2003 Este trabalho procura discutir questões que, a princípio, parecem obvias como o que é geomorfologia e pedologia, mas que quando do trato acadêmico revelam sua complexidade e discussão sobre seu entendimento e ação. Para isso um breve recuperar histórico de seu entendimento e sua utilização se fez necessário bem como as relações que se estabelecem entre
