Abstract Soil moisture is a fundamental determinant of plant growth, but soil measurements are rarely assimilated into grassland productivity models, in part because methods incorporating such data statistical and mechanistic yield models have not been adequately investigated. Therefore, our objectives were to (a) quantify relationships between situ biomass on grasslands Oklahoma (b) develop simple, biomass‐yield model for capable assimilating data. (as fraction available water capacity,...
This paper presents the study of modern pollen analogs from Balearic Islands. While similar studies have been largely applied to mainland areas, research focused on vegetation dynamics Mediterranean islands remains very rare. In this research, we combine surveys, analysis and multivariate statistics understand landscape composition. The main objectives are: (1) examine pollen-vegetation relationships in relation environmental land-use variables; (2) representation a mosaic structure; (3)...
Spatially and temporally unpredictable rainfall patterns presented food production challenges to small-scale agricultural communities, requiring multiple risk-mitigating strategies increase security. Although site-based investigations of the relationship between climate offer insights into how individual communities may have created long-term adaptations manage risk, inherent spatial variability climate-driven risk makes a landscape-scale perspective valuable. In this article, we model by...
Sedimentary charcoal analysis is increasingly used in archaeological and paleoecological research to examine human-environmental relationships at multiple scales. The recent availability of low-cost digital microscopes imaging software has resulted the rapid adoption image studies. However, most published studies include only minimal accounts configurations or utilize proprietary programs, thus hindering replication, standardization, comparability analyses across field. In an effort...
Understanding the dynamics between climate change and human adaptive strategies is a longstanding question driving paleoecological archaeological research in North America's Great Basin. We present multiproxy data from five sediment cores retrieved Paulina Marsh Fort Rock Basin, Oregon, an area renowned for its archaeology but lacking paleoenvironmental needed to fully contextualize those records. Radiocarbon, pollen, particle size, elemental, charcoal analyses of one core, geochronological...
ABSTRACT Long-term terrestrial ecosystem monitoring is a critical component of documenting outcomes land management actions, assessing progress towards objectives, and guiding realistic long-term ecological goals, all through repeated observation measurement. Traditional methods have evolved for specific applications in forestry, ecology, fire fuels management. While successful programs clear trained expertise, rigorous sampling protocols, new advances technology data can help overcome the...
Prescribed fire is increasingly utilized for conservation and restoration goals, yet there limited empirical evidence supporting its effectiveness in reducing wildfire-induced damages to valued resources of significant worth—whether natural, cultural, or economic. This study evaluates the efficacy prescribed wildfire severity LANDFIRE-defined vegetation classes impacted by 2017 West Mims event. Wildfire severity, measured using differenced normalized burn ratio (dNBR) index, was highly...
This paper proposes new anthropogenic pollen indicators for the Balearic Islands and attempts to assess gradients of human impact on vegetation in Mediterranean islands. A combination modern analogue studies, complemented by phytosociological descriptions ordination techniques using quantitative presence/absence data was used. Redundancy analysis allowed us evaluate relationships between types significant environmental variables propose regional (e.g., Centaurea, Rubus, Plantago...
The present study seeks to better understand the coupling of social and biophysical systems during late Pleistocene Holocene, a period characterized by changing interglacial conditions as well human population expansion intensified ecosystem management. approach consists combination patch-based archaeological survey methods, sediment column sampling for paleoenvironmental data, geospatial analysis, machine learning chronological unmixing, allowing systematic evaluation distribution intensity...
Soil moisture information could improve assessments of wildfire probabilities and fuel conditions, resulting in better fire danger ratings.
The logistics, costs, and capacity needed to complete extensive archaeological pedestrian surveys inventory cultural resources present challenges land managers. To address these issues, we developed a workflow combining LiDAR-derived imagery Deep Learning models tailored for Cultural Resource Management (CRM) programs on public lands. This combines Python scripts that easily fine-tune recognize features in with denoising QGIS steps improve the predictions' performance applicability. We this...

Prescribed fire is increasingly utilized for conservation and restoration goals, yet there limited empirical evidence supporting its effectiveness in reducing wildfire-induced damages to highly valued resources assets (HVRAs)—whether natural, cultural, or economic. This study evaluates the efficacy of prescribed wildfire severity LANDFIRE-defined vegetation classes HVRAs impacted by 2017 West Mims event, which burned across both prescribed-fire treated untreated areas within Okefenokee...
