Multi-objective optimization of fixed solar protections to reduce energy requirements in a temperate cold arid climate

open access: yesESTOA: Revista de la Facultad de Arquitectura y Urbanismo de la Universidad de Cuenca
The parametric approach used in this study explores various solar shading design scenarios during the early stages of the project. The objective is to reduce annual energy requirements in cold, arid, temperate climates, such as Mendoza, classified as BWk

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Enhancing security of land tenure for IDPs

open access: yesForced Migration Review, 2014
"The case of Maslakh in western Afghanistan is an example of translating Afghanistan’s new IDP Policy into reality. If successful the project will ensure security of land tenure for IDPs in urban settings and set a precedent for local integration of IDPs

A global perspective on the value of multi-level analysis as an enabler for achieving SDGs

open access: yesEuropean Spatial Research and Policy
With more than 50 percent of the global population living in urban areas, Sustainable Development Goal 11 on Sustainable Cities and Communities provides a critical lever for us to realise all other SDG goals.

Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

The recent decline of Montastraea annularis (complex) coral populations in western Curaçao: a cause for concern?

open access: yesRevista de Biología Tropical, 2006
Shallow leeward reefs off the western end of Curaçao are dominated by extensive populations of M. annularis (complex). These species are larger in size (mean= 66 cm diameter) than all other species, with few small colonies (10 cm observed within ...

Comparative analysis of conventional and unconventional thermal insulation materials for building construction

open access: yesESTOA: Revista de la Facultad de Arquitectura y Urbanismo de la Universidad de Cuenca
Nowadays, efforts are underway to minimize the negative environmental impact of the construction industry, which results from the use of non-renewable raw materials and the high energy consumption associated with their production. The primary strategy to

Two decades of resurrection studies: What have we learned about contemporary evolution of plant species?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Global climate change has altered the eco‐evolutionary trajectories of plant species, leading to observed shifts in phenotypes, such as earlier flowering. However, disentangling the contributions of plasticity and adaptation to trait changes remains challenging.
