Field methods for sampling tree height for tropical forest biomass estimation. [PDF]

Methods Ecol Evol, 2018
Abstract Quantifying the relationship between tree diameter and height is a key component of efforts to estimate biomass and carbon stocks in tropical forests. Although substantial site‐to‐site variation in height–diameter allometries has been documented, the time consuming nature of measuring all tree heights in an inventory plot means that most ...

Variation in stem mortality rates determines patterns of above-ground biomass in Amazonian forests: implications for dynamic global vegetation models. [PDF]

Glob Chang Biol, 2016
Abstract Understanding the processes that determine above‐ground biomass (AGB) in Amazonian forests is important for predicting the sensitivity of these ecosystems to environmental change and for designing and evaluating dynamic global vegetation models (DGVMs).

In search of a substitution model for coca in Colombia: Buffalo, cocoa, and coffee in Peasant Reserve Zones

Latin American Policy, Volume 14, Issue 3, Page 388-407, September 2023., 2023
Abstract For years Colombia has been the world's largest coca producer. Its public management of crops for illicit use has swung between eradication, substitution, and, recently legalization. Forced eradication has been shown to be ineffective, and legalization is an incipient option, so the Peace Agreement puts forward substitution as the path to ...

Assessing place‐based identities in the early Middle Ages: a proposal for post‐Roman Iberia

Early Medieval Europe, Volume 31, Issue 1, Page 23-50, February 2023., 2023
Sociological models of place‐based identity can be used to better understand the social dynamics of local communities and how they interact with their surroundings. This paper explores how these theoretical models of belonging to a place, in tandem with communal cognitive maps, can be applied to post‐Roman contexts, taking the Iberian Peninsula in the ...

Diversity in the invasive cacao pathogen Moniliophthora roreri is shaped by agriculture

Plant Pathology, Volume 71, Issue 8, Page 1721-1734, October 2022., 2022
The highest genetic diversity of the cacao pathogen Moniliophthora roreri is in Ecuador and Colombia, while it drastically decreased in recently invaded countries Abstract Frosty pod rot disease of cacao (FPR), caused by the fungus Moniliophthora roreri, has severely impacted the production of cocoa in Latin America since its discovery.

Baroque Modernity in Latin America: Situating Indigeneity, Urban Indigeneity and the Popular Economy

Bulletin of Latin American Research, Volume 41, Issue 1, Page 6-20, January 2022., 2022
This article uses the Bolivian city of El Alto as a lens through which to evaluate the place of urban indigeneity and the popular economy within Latin American modernity. Whilst some express worries over the erosion of indigenous ways of life and others see urban indigenous practices as defying capitalist modernity, I argue that these emergent forms of
