In this article, we endeavor to shed new light on the consequences of tribalism in the present day, one of the most important of which is the threat posed by lone wolf actors and the emergence of autonomous cells that operate with no central direction. To better acquaint the reader with the theoretical models used in this article -- in particular the Trinitarian model of Carl von Clausewitz -- we begin with historic models dating back to Alexander the Great. The central focus of our article posits a reconceptualization of tribalism as a driving force behind the global jihadist phenomenon. We will go into the cases of Iraq and Afghanistan in some depth, believing that it is necessary to provide a close examination of these case studies to better understand the emergence of jihadist lone wolves who operate both in the ungoverned spaces of the Middle East and South Asia and in their Western homelands. We conclude with an examination of cases of jihadist lone wolf terrorism involving recent converts to radical Islam in the U.S. Finally, our article focuses on the emerging security threats posed by lone wolves, autonomous cells, and the challenges ahead for the military, security, and intelligence services.

Bees generally use different botanical sources of resins for the production of propolis. The elucidation of botanical sources of propolis and identification of the effects of seasonality on the chemical profile of propolis are recognized as two important aspects in the development of a high quality product. Thus, our objective was to elucidate the botanical source and identify the effect of the seasons on the chemical profile of propolis produced in southern Brazil. The chemical profile of the samples was analysed by spectrophotometric and chromatographic techniques and the results were coupled to multivariate analysis. Field observation of the foraging behaviour of Apis mellifera L. revealed its preference for the Baccharis dracunculifolia DC. species. p-Coumaric acid, 3, 4-dicaffeoylquinic acid, 3, 5-dicaffeoylquinic acid, drupanin, and artepillin C which were identified in both plant and propolis samples. Moreover, higher artepillin C amounts have been detected in samples collected in the summer and autumn, while the main compounds of p-coumaric acid and quercetin were available in spring and winter sampled propolis, respectively. Baccharis dracunculifolia has been identified as a plant species preferred by A. mellifera in foraging resin for the production of propolis in southern Brazil. The contents of balsam, total phenolic compounds, and flavonoids varied significantly over the seasons, with values above the minimum required by the legislation, thus assuring a quality pattern for this biomass.
