Journal of the Royal Anthropological Institute, EarlyView.The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.

Exotic nuclei with charm and bottom flavor
EPJ Web of Conferences, 2010 We discuss the possibility of existence of exotic nuclei containing charm and bottom mesons. We study the interaction between $ar{D}$ (B) mesons and nucleons from view of heavy quark symmetry, and derive the one pion exchange potentials.

Intrinsic charm in B-meson decays [PDF]
Nuclear Physics B - Proceedings Supplements, 2003 Light cone hadron wave functions support Fock states of arbitrarily high particle number: their heavy quark content arises naturally through QCD interactions. We discuss what role c\bar c pairs, intrinsic to a hadron's structure, can play in B-meson decays.

Integrative Zoology, EarlyView.Soil drought imposes moderate, temporary costs on a strictly fossorial amphisbaenian reptile. However, these animals seem to cope with, at least, moderately short droughts thanks to their peculiar adaptations to living in an underground environment. ABSTRACT The physiological traits of animals can be strongly influenced by climatic fluctuations, and ...

Integrative Zoology, EarlyView.This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

Evaluating the efficacy of tagging adhesives for insect tracking
Agricultural and Forest Entomology, EarlyView.Two‐part epoxy resin delivered the strongest RFID tag adhesion on carabid beetles, exceeding polyvinyl acetate, cosmetic latex and cyanoacrylate adhesives. Adhesive performance was consistent across Harpalus, Leistus and Poecilus; species effects were non‐significant, supporting a broadly applicable protocol for carabid RFID tagging studies.

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

EPJ Web of Conferences, 2014 Quantum entanglement of K and B mesons allows for a direct experimental test of time-reversal symmetry independent of CP violation. The T symmetry can be probed by exchange of initial and final states in the reversible transitions between flavor and CP ...

Conservation Biology, EarlyView.Abstract Contemporary conservation goals have a greater chance of success when practitioners collaborate with Indigenous communities. The importance of such collaborations has spurred calls by Western and Indigenous researchers to engage in equitable coproduction of ecological research that integrates multiple ways of knowing.

Conservation Science and Practice, EarlyView.Abstract Outdoor recreation and the infrastructure that supports it can impose a wide range of effects on wildlife, and impacts can vary in their severity based on taxa, the surrounding landscape matrix, and the manner in which recreational spaces are managed.
