Phyllanthus rufuschaneyi: a new nickel hyperaccumulator from Sabah (Borneo Island) with potential for tropical agromining
Kinabalu Park — 2018 — WHEE2CD08FF2B
A new nickel hyperaccumulator plant, Phyllanthus rufuschaneyi, has been discovered in Sabah (Borneo Island), with significant potential for tropical agromining. This rare species, found only on Lompoyou Hill near Kinabalu Park, can accumulate high concentrations of nickel and is easily cultivated, making it a promising candidate for metal extraction from soil using plants. The study identifies its unique flower structure, suggesting pollination by Epicephala moths, and classifies it within the subgenus Gomphidium, representing the most western species in this group. Its potential use in agromining not only offers a novel approach to metal extraction but also provides a mechanism for conserving this endangered taxon, emphasizing the importance of habitat and germplasm preservation for rare species utilized in green technologies.
Phylogenetically diverse native systems are more resistant to invasive plant species on Robben Island, South Africa
Robben Island — 2018 — WHE09514E730F
Phylogenetically diverse native plant systems on Robben Island, South Africa, exhibit greater resistance to invasive species. The study found that alien invasive plants tend to flower later and for longer periods, relying more on abiotic pollination and hermaphroditic traits, whereas native species depend on biotic pollinators, flower earlier, and are predominantly dioecious. Additionally, a facilitative interaction between an invasive legume and other invasive plants was observed, but this did not affect the phylogenetic structure of plant communities. The research employed multiple approaches to explore functional traits linked to invasion success and the role of phylogenetic structure in biotic interactions.
Phylogeny of the genus Pseudosinella (Hexapoda, Collembola) from the Western Carpathians caves reveals Miocene diversification
Caves of Aggtelek Karst and Slovak Karst — 2018 — WHEFCC08AAA53
A groundbreaking study reveals that the Western Carpathians, part of Europe's northernmost region with obligate cave fauna, served as a key speciation center for collembolan species. Phylogenetic analysis of the genus Pseudosinella indicates that two distinct lineages diverged approximately 9.54 million years ago during the Miocene epoch, followed by further diversification in P. paclti (8.36 mya) and P. aggtelekiensis (6.99 mya). Unlike P. aggtelekiensis, which lacks related surface species, P. paclti exhibits a broader distribution across caves, subterranean habitats, and soil environments. The research combines morphological and molecular traits to reconstruct evolutionary relationships, suggesting that allopatric speciation driven by geographic isolation played a pivotal role in the diversification of cave-dwelling Pseudosinella species.

Physical, Mechanical and Chemical Characterization on Ancient Brick Masonry of Monuments, Bagan, Myanmar
Bagan — 2018 — WHE8717C35797
Ancient bricks from Bagan's monuments, dating back to the 11th to 18th centuries, exhibit remarkable resilience against environmental degradation while maintaining high compressive strength. A study by San et al. (2018) reveals that these bricks, despite their age, show good water absorption properties and vary in mechanical strength depending on their location within monuments. Chemical analysis using Energy-dispersive X-ray (EDX) techniques indicates that ancient bricks retain their original composition, though not identical to modern counterparts produced nearby. The research also highlights the importance of matching materials used in conservation efforts to preserve the authenticity of these UNESCO World Heritage Sites. This study underscores the durability of traditional brick-making techniques and provides critical data for informed restoration practices.
Phytoliths as an indicator of early modern humans plant gathering strategies, fire fuel and site occupation intensity during the Middle Stone Age at Pinnacle Point 5-6 (south coast, South Africa)
The Emergence of Modern Human Behaviour: The Pleistocene Occupation Sites of South Africa — 2018 — WHE1E84A00B45
Research at Pinnacle Point 5-6 North (South Africa) reveals the first evidence of intentional gathering and use of Restionaceae family plants by Middle Stone Age hunter-gatherers, marking a significant shift in plant foraging strategies. The study used phytolith analysis to reconstruct past human behavior, showing that during Marine Isotope Stage (MIS) 5, humans built fast fires using grasses for potential shellfish cooking. By MIS 4, there was a transition toward intensive dry wood exploitation, likely to improve silcrete heating, coinciding with changes in stone tool technology and site occupation intensity. The findings highlight the complex interplay between human behavior, fire control, and environmental adaptation during this critical period of modern human emergence.
Pilgrimage in Islam: Traditional and Modern Practices
Medina of Fez — 2018 — WHE8260B362AA
Islamic pilgrimage extends far beyond the Hajj, encompassing diverse practices and sites that transcend sectarian boundaries. Research reveals that Muslims engage in 'replacement hajjs' (ziyārat), visiting graves, shrines, and other holy sites to seek blessings (baraka) from saints, often blending Shia, Sunni, and Sufi traditions. These pilgrimages, including those to Karbala, Konya, Fez, and Samarkand, involve fluid rituals, miracles, and syncretic elements that defy simplistic classifications. Modern pilgrimage is further shaped by commodification, technology, and virtual experiences, creating dynamic, multi-dimensional practices. The study argues that understanding Islamic pilgrimage requires examining texts alongside beliefs, rituals, objects, and emotions, challenging orthodoxies that dismiss ziyārat as heretical.

Plant Microfossil Results from Old Kiyyangan Village: Looking for the Introduction and Expansion of Wet-field Rice (Oryza sativa) Cultivation in the Ifugao Rice Terraces, Philippine Cordilleras
Rice Terraces of the Philippine Cordilleras — 2018 — WHE322005BA01
A groundbreaking analysis of plant microfossils from Old Kiyyangan Village, Ifugao Province, reveals preliminary evidence for the introduction and expansion of wet-field rice (Oryza sativa) cultivation in the Philippine Cordilleras. Pollen, phytolith, and starch analyses of 12 sediment samples date human activity to approximately 810–750 cal. b.p., with the first rice remains appearing around 675 cal. b.p. A significant increase in these remains after 530–470 cal. b.p. suggests a late expansion of rice cultivation, corroborating previous studies. This study provides the initial sediment-derived ancient starch and phytolith evidence for Oryza sativa in the Philippines, offering new insights into the agricultural history of this UNESCO World Heritage Site.
Plant Supplying Strategies in an Islamic Omani Harbour City: Archaeobotanical Analysis from a Workshop (B39) in Qalhāt (XIVth-XVIth c. AD)
Ancient City of Qalhat — 2018 — WHE9717AAD347
Archaeobotanical analysis of workshop B39 at Qalhat, an Islamic harbor city in Oman (14th–16th century AD), reveals a significant presence of tropical crops such as Asian rice, finger millet, and various legumes, suggesting complex plant supply strategies. The distribution of these remains indicates specialized domestic activities, including food preparation and crop processing, likely occurring in room E. While the origin of these crops—whether imported or locally cultivated—remains uncertain, the Indian subcontinent is proposed as a probable source, with Yemen also considered. This study advances understanding of plant consumption and agrosystem integration during this period, addressing a gap in archaeobotanical research on Islamic sites in eastern Arabia.
Plant-Female Iconography in Neolithic Europe
Megalithic Temples of Malta — 2018 — WHE4897ACF4E6
A strong symbolic association between plants and female imagery emerged during the Neolithic transition to agriculture, evident from anthropomorphic figurines across Europe. This link, marked by cereal grain eyes and plant motifs on figurines, tracked the spread of farming into Europe. Notably, megalithic-era symbols in Malta, including engravings on a monumental woman statue at Tarxian temple, reinforce this continuity, spanning from the Neolithic period through the Chalcolithic era and into stratified Bronze Age societies. The study highlights the persistence of plant-female iconography, reflecting deeper cultural and agricultural shifts during Europe's secondary products revolution.
Plazas and Processional Paths in Tiwanaku Temples: Divergence, Convergence, and Encounter at Omo M10, Moquegua, Peru
Tiwanaku: Spiritual and Political Centre of the Tiwanaku Culture — 2018 — WHE8AC7775E96
Excavations at the Omo M10 Tiwanaku temple in Moquegua, Peru (AD 500–1100), revealed divergent processional pathways that challenge previous interpretations of Tiwanaku ceremonial architecture. While a central axial route—marked by doorways, staircases, stelae, and U-shaped structures—led to the sunken court and shrine, lateral pathways connected isolated walled patios with roofed chambers, suggesting these functioned as specialized chapels for distinct groups or pluralistic cultic activities. This finding implies a complex social structure within Tiwanaku society, potentially reflecting mediation between ethnicities, genders, or other pluralistic entities. The study contrasts these observations with Kolata's 'Taypi' model, proposing a structural amalgam of center and complementary halves to explain bilateral complementarity in the state.
Pleistocene geodynamic evolution of the Arlanzón valley: implications for the formation of the endokarst system and the open air archaeological sites of the Sierra de Atapuerca (Burgos, España)
Archaeological Site of Atapuerca — 2018 — WHE97E950C951
A new analysis of the Arlanzón valley's Pleistocene geodynamic evolution reveals that tectonic uplift accelerated incision rates, shaping the valley's fluvial terraces and influencing the formation of sub-horizontal cave levels in the Sierra de Atapuerca. This study links three key cave levels (T2, T3, and T4/T5) to specific terrace elevations, suggesting rapid phreatic passage development compared to slower vadose entrenchments. The research also highlights how the exhumation of a Neogene limestone layer provided Neanderthals with accessible flint sources during MIS 3 and 4. By integrating LiDAR-derived terrace heights and chronological data, the study reconstructs downcutting phases, offering insights into the valley's complex geological history and its archaeological significance.
Pluralising Political Forests: Unpacking “the State” by Tracing Virunga's Charcoal Chain
Virunga National Park — 2018 — WHEAE6596C777
Virunga National Park exemplifies the complex interplay of political forces shaping its conservation landscape. This study reveals that the notion of 'the state' is not monolithic but rather a dynamic entity influenced by regional warfare, non-state militarization, and transnational processes. By tracing the illegal charcoal chain within the park, researchers demonstrate how authority in Virunga has been transformed through particularization, transnationalization, and regionalization, leading to a regulatory landscape marked by overlapping and conflicting political forces. This approach challenges traditional understandings of stateness and highlights the multifaceted nature of political forests, offering new insights into the governance challenges faced by protected areas.
Political Ecologies of Dynamic Wetlands: Hydrosocial Waterscapes in the Okavango Delta
Okavango Delta — 2018 — WHEA7B1DE189B
Dynamic wetlands, particularly those with variable flooding regimes, have been understudied within political ecology frameworks. This research highlights the Okavango Delta as a 'hydrosocial waterscape,' where complex socioecological relationships and power dynamics are shaped by flooding patterns. The study focuses on two key themes: access to resources and governance structures, revealing how these factors interact with environmental variability to influence rural livelihoods in Botswana. By integrating political ecology with hydrological studies, the research offers a nuanced understanding of how dynamic wetland systems challenge traditional conservation and development paradigms.
