1. Leaving home: Technological and landscape knowledge as resilience at pre-Holocene Kharaneh IV, Azraq Basin, Jordan

   Macdonald, Danielle_A; Maher, Lisa_A (September 2022, The Holocene)

   Humanity’s relationship with the environment during the Holocene, and into the Anthropocene, is structured around our dependance on agricultural production, which has resulted in risk mitigation strategies that include intensive landscape modifications, among other tactics. However, to understand broader patterns of human resilience and the shifts in human/environment relationships, we need to look further back in time. Through this paper, we explore cultural strategies of risk management and resilience in pre-Holocene communities and how these practices allowed hunter-gatherer communities to adapt to a changing environment. For over 1000 years, the Epipalaeolithic site of Kharaneh IV was a focal point on the landscape for hunter-gatherer groups, acting as an aggregation site for Early and Middle Epipalaeolithic peoples. Located in the eastern desert of Jordan, at the time of occupation the site was a lush wetland surrounded by a rich grassland environment, providing abundant food and other resources for the site’s occupants. However, over time the wetland began to dry up and by 18,600 cal BP Kharaneh IV was abandoned. In this paper, we discuss the final occupation of Kharaneh IV, linking the site’s abandonment to the increasing aridification of eastern Jordan. Environmental change led to the eventual abandonment of Kharaneh IV and other nearby sites, as people relocated within the Azraq Basin in search of new water resources during the Holocene. Flexible technological strategies and knowledge of the landscape created resilient cultural practices that allowed these communities to use population movement as a risk management strategy.

2. The Black Desert Drone Survey: New Perspectives on an Ancient Landscape

   https://doi.org/10.3390/rs14030702  

   Hill, Austin Chad; Rowan, Yorke M. (February 2022, Remote Sensing)

   This paper presents the results of a large scale, drone-based aerial survey in northeastern Jordan. Drones have rapidly become one of the most cost-effective and efficient tools for collecting high-resolution landscape data, fitting between larger-scale, lower-resolution satellite data collection and the significantly more limited traditional terrestrial survey approaches. Drones are particularly effective in areas where anthropogenic features are visible on the surface but are too small to identify with commonly and economically available satellite data. Using imagery from fixed-wing and rotary-wing aircraft, along with photogrammetric processing, we surveyed an extensive archaeological landscape spanning 32 km2 at the site of Wadi al-Qattafi in the eastern badia region of Jordan, the largest archaeological drone survey, to date, in Jordan. The resulting data allowed us to map a wide range of anthropogenic features, including hunting traps, domestic structures, and tombs, as well as modern alterations to the landscape including road construction and looting pits. We documented thousands of previously unrecorded and largely unknown prehistoric structures, providing an improved understanding of major shifts in the prehistoric use of this landscape.

3. Renewing the Belize Archaic Project in 2019

   Rosenswig, Robert M (November 2023, Research Reports in Belizean Archaeology)

   The Archaic period in the Maya region represents six millennia (7000-1000 BCE) when non-ceramic-using peoples began to experiment with domesticates and reduce their settlement ranges. The single longest epoch of the Mesoamerican chronology, these early millennia are often overshadowed by the investigation of more recent peoples who built cities and have left evidence of elaborate artistic traditions. The Belize Archaic Project (BAP) began work over 20 years ago after the fortuitous discovery of aceramic deposits containing heavily patinated lithic tools and debitage under Postclassic settlements in the Freshwater Creek drainage of northern Belize. The 2019 field season marks a renewed phase of this project and initiates a program of systematic settlement survey and test excavations. This paper presents initial results of a systematic program of auguring that documented 87 Archaic-period sites and excavations at four of these locales during the summer of 2019. The renewed BAP investigates local land use patterns and foraging adaptation as well as the dynamic manner in which they affect (and are impacted by) climate change and evolving local forest and lacustrine ecology.

4. Rainforest phenology: flower, fruit and seed production from biweekly collections of 200 traps in the Yasuní Forest Dynamics Plot, Ecuador, 2000-2018

   We provide data on flowering and fruiting phenology from an equatorial, ever-wet rainforest in eastern Ecuador, in Yasuni National Park. This is the first long-term study (18 years) of phenology in a diverse equatorial neotropical forest. Although the site is ever-wet, there is some seasonal variation in rainfall and irradiance. One major question was to determine whether the seasonal variation in climate was sufficient to drive seasonality in reproduction in this hyper-diverse forest. The study began in 2000 with various funding, and became an LTREB-funded project in 2006. We used twice monthly censuses of 200 traps to document phenology. Parts of >1000 species were identified in the traps in the 18 year period (ending early in 2018), including trees, shrubs, lianas and epiphytes. Parts identified included buds, flowers, mature fruits and mature seeds, and aborted, damaged and immature fruits and seeds. The project is on-going, and additional data will be added as it is processed.

5. Long-term Dynamics in Soil Field Available Nitrogen and Potentially Mineralizable Nitrogen in a Chihuahuan Desert Grassland at the Sevilleta National Wildlife Refuge, New Mexico (1989-2014)

   https://doi.org/10.6073/pasta/67b0cfde84800a08d37e4e94a403bfa8  

   White, Carleton; Moore, Douglas I. (January 2016, Environmental Data Initiative)

   Associated with a project that was based upon the assumption that nitrogen may limit net primary plant production in desert grasslands, this project began measuring available inorganic soil N and potentially mineralizable N of soils at two desert grassland locations. Both available N and potentially mineralizable N were greatest following a drought period in 1989, declined during wetter periods that followed and remained relatively stable until another extended drought period. After drought in 1995-6, both forms of soil N increased, indicating the potential for greater NPP following drought and lower potential NPP during periods of normal precipitation.
