Nutrient use by tropical ant communities varies among three extensive elevational gradients: A cross‐continental comparison

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 12, Page 2212-2229, December 2023., 2023
Abstract Aim Many studies demonstrate that climate limits invertebrates along tropical elevational gradients, but we have only a rudimentary understanding of the role of nutrient limitation and climatic seasonality. Here we examined the relationships between ant community structure, nutrient use and season along three undisturbed elevational gradients,

“No Colonial Baggage”: Imagining a Decolonised Australia‐Africa Relations

open access: yesAustralian Journal of Politics &History, Volume 69, Issue 3, Page 522-541, September 2023., 2023
As part of its strategy to win African votes for election to the UN Security Council (2008–12), Canberra sought to leverage its soft power potential by presenting Australia as having “no colonial baggage” in Africa while framing Australia as “a country from the Global North, located in the Global South,” and one that would “work with other small and ...

Late Miocene Exhumation of the Western Cordillera, Ecuador, Driven by Increased Coupling Between the Subducting Carnegie Ridge and the South American Continent

open access: yesTectonics, Volume 42, Issue 1, January 2023., 2023
Abstract The subduction of bathymetric highs, such as aseismic ridges, leads to far‐reaching changes in the dynamics of subduction zones with increased plate coupling and deformation in the upper plate. Subduction of the submarine Carnegie Ridge on the Nazca Plate has fundamentally impacted late Cenozoic magmatism and tectonic activity in the northern ...

Correlations Between Subduction of Linear Oceanic Features and Arc Volcanism Volume Around the Pacific Basin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 23, Issue 12, December 2022., 2022
Abstract Arc volcanoes, created by magma generated from the dehydration of subducting slabs, show great variability in their sizes and along‐arc spatial distributions. In this study, we address a fundamental question, namely, how do subduction zones and volcanic arcs respond to the subduction of “atypical” oceanic lithosphere.

Socio‐economic status, executive functions, and theory of mind ability in adolescents: Relationships with language ability and cortisol

open access: yesBritish Journal of Developmental Psychology, Volume 39, Issue 1, Page 19-38, March 2021., 2021
Socio‐economic status (SES) is linked to the development of cognitive abilities, particularly language and executive processes. It is unclear whether these represent a single or independent correlates. We studied 110 Ecuadorian youths aged 12–17 with measures of SES, language, executive function, and theory of mind (ToM), a.k.a. mentalizing.

Fictitious commodification and agrarian change: Indigenous peoples and land markets in Highland Ecuador

open access: yesJournal of Agrarian Change, Volume 21, Issue 1, Page 3-24, January 2021., 2021
Abstract Creating private property rights and establishing land markets were fundamental to the historical development of capitalism in the Global North and remain at the centre of capitalist development in the Global South. This article contributes to debates about these processes by analysing the relationship between land markets and indigenous ...

Contingent valuation and rural potable water systems: A critical look at the past and future

open access: yesWIREs Water, Volume 6, Issue 2, March/April 2019., 2019
High‐quality contingent valuation studies can estimate the value communities place on potable water resources. Determining the value of environmental goods that impact human populations, such as potable water, is often highly problematic. The all‐too‐common lack of realistic markets for the provisioning of these goods necessitates the use of nonmarket ...

The Globalization of Traditional Medicine in Northern Peru: From Shamanism to Molecules

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2013, Issue 1, 2013., 2013
Northern Peru represents the center of the Andean “health axis,” with roots going back to traditional practices of Cupisnique culture (1000 BC). For more than a decade of research, semistructured interviews were conducted with healers, collectors, and sellers of medicinal plants.

Pollination ecology in the tropical Andes: moving towards a cross‐scale approach

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2312-2345, December 2025.
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Carbon Emissions From Low‐Order Streams in a Tropical, High‐Elevation, Peatland Ecosystem Are Mediated by Catchment Morphology

open access: yesWater Resources Research, Volume 61, Issue 4, April 2025.
Abstract Inland waters emit large amounts of carbon and are key players in the global carbon budget. Particularly high rates of carbon emissions have been reported in streams draining mountains, tropical regions, and peatlands. However, few studies have examined the spatial variability of CO2 concentrations and fluxes occurring within these systems ...
