Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Wild bee diversity and land use: A case study in a mountain agroecosystem of the Serranía de Ronda, southern Spain

open access: yesInsect Conservation and Diversity, EarlyView.
Orchards supported the highest wild bee diversity and functional diversity, highlighting their role in maintaining bee communities in Mediterranean agroecosystems. Landscape heterogeneity positively influenced functional evenness and dispersion of wild bee communities, underscoring the importance of diverse landscapes for bee conservation. The presence

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.

Independent Partitions in Boolean Algebras [PDF]

open access: yes, 2012
This dissertation introduces a generalization of the cardinal invariant independence for Boolean algebras, suggested by the proof of the Balcar-Franek Theorem. The objects of study are independent sets of partitions under this new notion of independence.

To Grandmother's House We Go: Informal Childcare and Female Labor Mobility

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We document how childcare costs and the location of extended family influence the labor supply and mobility of US women. Women return to their home locations immediately before fertility events, suggesting that informal childcare needs may motivate home migration. Women who live near their parents have lower child earnings penalties.

Lactate does not replace glucose for maintaining the viability of mouse and human glioma cells

open access: yesOncologie
Aerobic lactic acid fermentation (the “Warburg effect”) is associated with OxPhos insufficiency and altered energy metabolism in most cancers. Whether lactate is a major fuel in cancer cells remains debated.
