A global assessment of animal community responses to agricultural management
Conservation Biology, EarlyView.Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

Conservation Biology, EarlyView.Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

Lorentz violations in multifractal spacetimes
European Physical Journal C: Particles and Fields, 2017 Using the recent observation of gravitational waves (GW) produced by a black-hole merger, we place a lower bound on the energy above which a multifractal spacetime would display an anomalous geometry and, in particular, violations of Lorentz invariance ...

Revista de Arquitectura (Bogotá), 2009 La investigación en estructuras adaptables manifiesta que el hábitat arquitectónico actual se presenta en su mayoría rígido, estático e inmodificable, haciendo casi imposible futuras transformaciones, así como cambios de forma y de espacio en el tiempo con fines adaptativos.

Coinvasional disruptions to island pollinator networks
Conservation Biology, EarlyView.Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Generalizations of the Pontryagin and Husain-Kuchař actions to manifolds with boundary
Journal of High Energy Physics, 2019 In this paper we study a family of generalizations of the Pontryagin and Husain-Kuchǎr actions on manifolds with boundary. In some cases, they describe well- known models — either at the boundary or in the bulk — such as 3-dimensional Euclidean general ...

Psychometric framework for coexistence with large carnivores
Conservation Biology, EarlyView.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

Using the capabilities approach to achieve people‐centered conservation
Conservation Biology, EarlyView.Abstract Top‐down interventions carried out by state and nonstate institutions to conserve biodiversity and improve the lives of forest‐proximate people (FPP) in the Global South tend to reflect economistic understandings of human well‐being. More progressive and people‐centered conservation projects are guided by normative visions of how the world ...
