Hidden symmetries from extra dimensions

Journal of High Energy Physics
In Kaluza-Klein compactifications, some symmetries of the higher dimensional theory are preserved in lower dimensions, others are broken, and occasionally, there are symmetry enhancements.

McVittie solution in f(T) gravity

European Physical Journal C: Particles and Fields, 2017
We show that McVittie geometry, which describes a black hole embedded in a FLRW universe, not only solves the Einstein equations but also remains as a non-deformable solution of f(T) gravity.

Functional homogenization of terrestrial mammals outside protected areas in the Hengduan Mountains, China

Conservation Biology, EarlyView.
Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Defining and identifying relevant stakeholders to advance effective conservation

Conservation Biology, EarlyView.
The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

Conservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Effectiveness of territorial protection categories in conserving an endemic island bird during population fluctuation

Conservation Science and Practice, EarlyView.
Static boundaries of protected areas failed to capture the Canary Islands stonechat's shifting distribution patterns. Abstract Protected areas represent cornerstones of biodiversity conservation on oceanic islands, yet their effectiveness for endemic species remains poorly evaluated. We assessed how various territorial protection categories conserve an

May I pick your brain? Local minds as living cadastres in a Portuguese eleventh‐century lawsuit

Early Medieval Europe, EarlyView.
In the context of a dispute with the monastery of Lorvão, in the late eleventh century, the monks of Vacariça, near Coimbra (modern Portugal), carried out a field enquiry in the village of Recardães. This was part of a failed attempt to repossess a number of land plots that they claimed were theirs, but had lost control of.
