Article Reference Rare Element Enrichment in Lithium Pegmatite Exomorphic Halos and Implications for Exploration: Evidence from the Leinster Albite-Spodumene Pegmatite Belt, Southeast Ireland
Pegmatitic deposits of critical metals (e.g., Li, Ta, Be) are becoming increasingly significant, with growing interest in understanding metal enrichment processes and potential vectors to aid the discovery of new resources. In southeast Ireland, the Leinster pegmatite belt comprises several largely concealed Li-Cs-Ta albite-spodumene-type pegmatites. We carried out detailed mineralogical characterization and whole-rock geochemical analyses of six drill cores intersecting pegmatite bodies and their country rocks. Exomorphic halos 2–6 m thick, enriched in Li, Rb, Be, B, Cs, Sn and Ta, are identified in both mica schists and granitic rocks adjacent to spodumene pegmatites. Metasomatism in wall rocks visible to the naked eye is restricted to a few tens of centimeters, suggesting country rock permeability plays a key role in the dispersion of these fluids. We propose that halos result from the discharge of rare element-rich residual fluids exsolved near the end of pegmatite crystallization. Halo geochemistry reflects the internal evolution of the crystallizing pegmatite system, with residual fluid rich in incompatible elements accumulated by geochemical fractionation (Be, B, Cs, Sn, Ta) and by auto-metasomatic resorption of spodumene and K-feldspar (Li, Rb). The possibility of identifying rare-element enrichment trends by analysis of bedrock, stream sediments and soils brings opportunities for mineral exploration strategies in Ireland and for similar albite-spodumene pegmatites worldwide.

Article Reference The ants of the Galápagos Islands (Hymenoptera, Formicidae): a historical overview, checklist, and identification key
The Galápagos ant fauna has long been understudied, with the last taxonomic summary being published almost a century ago. Here, a comprehensive and updated overview of the known ant species of the Galápagos Islands is provided with updated species distributions. The list is based on an extensive review of literature, the identification of more than 382,000 specimens deposited in different entomological collections, and recent expeditions to the islands. The ant fauna is composed of five subfamilies (Dolichoderinae, Dorylinae, Formicinae, Myrmicinae, and Ponerinae), 22 genera, 50 species, and 25 subspecies, although three species (Crematogaster crinosa Mayr, 1862, Camponotus senex (Smith, 1858), and Solenopsis saevissima (Smith, 1855)) are considered dubious records. Finally, an illustrated identification key of the species found in the archipelago is presented.

Article Reference FIRST RECORD OF FIVE ANT SPECIES (HYMENOPTERA: FORMICIDAE) FROM RWANDA
Ant studies conducted in Rwanda have reported a total of 105 ant species. However, this is an underestimation of the total ant richness since Rwanda is in a region rich in biodiversity. To fill the gaps, ants have been sampled in planted forests, coffee plantations, and different other land use types since 2017. Specimens have been collected using pitfall traps and hand collection, digitized, and identified to subfamily, genus, and species level. Results indicated that five ant species were found in Rwanda for the first time. These are Camponotus acvapimensis, Camponotus schoutedeni, Camponotus sericeus, Odontomachus assiniensis and Tetramorium sericeiventre. Specimens are deposited at the Royal Belgian Institute of Natural Science and the Rwanda Ant Collection. We recommend more ant studies focussing on their mode of living. This will result in more ant species newly recorded in the country and possibly new to science.

Article Reference Can habitat characteristics of a West African forest-savanna mosaic landscape model bee community composition?
Bees are vital to both ecosystems and humans worldwide; supplying a range of key support facilities for the successful breeding of the majority of flowering plants. The aim of this study was to assess the bee species composition in a Sudano-Guinean savanna zone and determining the impact of a set of environmental parameters influencing this species composition in four habitat types. Sampling was carried using yellow pan traps protocol. A total of 846 bees belonging to 3 families, 25 genera and 52 species were collected. The largest number of bee individuals was found in the Apidae family. The most abundant species was Hypotrigona sp. The highest bee species and number of individuals was recorded in the shrubby savanna. Bee species diversity and abundance were found closely correlated with the plant diversity. Gaining a better understanding of the factors influencing bee community dynamics in the given landscape can provide valuable information for conservation efforts, habitat management and help identifying species which ones could be domesticated.
