Quando o campo está a 5 mil metros de altitude: Orduña, Peru [PDF]

open access: yesPonto Urbe, 2017
Dia 9, sabado, llegada a Puno Sofia y yo embarcamos el sabado en Lima a las 19:30 rumbo a Puno. Como no hay aeropuerto en esta ciudad, a raiz de su accidentada topografia, bajamos a las 21:10 en Juliaca, ciudad vecina de 200.000 habitantes y desde ahi, en una van, en una hora de viaje, llegamos finalmente a la sede del Departamento de Puno.

The role of mesoscale weather effects in simulating pyroconvection: A case study of the Santa Coloma de Queralt wildfire

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This large‐eddy simulation study on pyroconvection shows that the added value from resolving the mesoscale explicitly is found in the timing of pyrocumulus formation and circulation changes. The circulation of the convective plume itself is not substantially different between the simulations. Abstract Extreme wildfire events are characterised by strong

Retrospective image analysis for long‐term demography using Google Earth imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

ELEVATIONAL RANGES AND LOCAL EXTINCTION RISK OF BEETLES OCCURRING IN THE “CAMPOS DE ALTITUDE” IN SOUTHEASTERN BRAZIL

open access: yesOecologia Australis, 2016
The mountaintops of the Atlantic Rainforest in Southeastern Brazil are dominated by high altitude grasslands, named Campos de Altitude (CA). Considering the location and the smaller habitat areas of communities on the mountaintops and the high frequency of endemic species, the assemblages in these habitats are particularly threatened by climate ...

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We
