Journal of Biogeography, Volume 53, Issue 4, April 2026.ABSTRACT Aim The assembly of tropical tree floras is complex, involving many lineage‐specific histories; however, focusing on the biogeographic history of diverse clades can reveal general patterns. We investigated the historical biogeography of the ecologically important Brazil nut clade (Lecythidoideae) to: (1) expand prior phylogenies with greater ...

Revista de Biología Tropical, 2010 The phenotypic structure within and between plant populations is generally influenced by their distribution patterns in space and time; therefore, the study of their divergence is a central issue for the understanding of their microevolutive processes ...

The Pioneer Anomaly and Its Implications
, 2005 The Pioneer 10/11 spacecraft yielded the most precise navigation in deep space to date. However, their radio-metric tracking data has consistently indicated the presence of a small, anomalous, Doppler frequency drift. The drift is a blue-shift, uniformly

Clinical Psychology &Psychotherapy, Volume 33, Issue 2, March/April 2026.ABSTRACT Although diagnostically distinct from suicidal behaviour and, by definition, not intended to cause death, nonsuicidal self‐injury (NSSI) remains one of the strongest predictors of suicide. NSSI and suicidal behaviour appear to share a suicidal state of mind, marked by detachment from life and ambivalence toward death.

Haunted by Houses: Built and Lived Absences in a Transnational Mexican Community
Anthropology of Consciousness, Volume 37, Issue 1, Spring 2026.ABSTRACT Globally, millions of migrants have sent money home to build a house. In early phases of migration, remittance houses are aspirational objects that materialize the continuous belonging of migrants to a community. In later stages, experiences of loss, estrangement, deportation, and death increasingly challenge these attachments.

Three Decades of Butterfly–Plant Interaction Turnover Explained by Climate and Species Loss
Ecology Letters, Volume 29, Issue 3, March 2026.Long‐term biodiversity loss reshapes interaction dynamics inpollination networks. Communities become increasingly dominated bygeneralist species that are more capable of rewiring interactions thanspecialists. However, rewiring declines over time as species lossreduces the pool of potential partners, progressively raising thecontribution of species ...

, 2017 In this work, we study the late-time cosmological solutions of f(R,T)=g(R)+h(-T) models assuming that the conservation of the energy-momentum tensor (EMT) is violated.
