Summary: This study proposes a new method based on the Kaiser effect method and Sn Model to evaluate the ground stress distribution in shale oil reservoirs. Through calculation and simulation, it is found that regional tectonic stress and paleo topography are the main influencing factors of ground stress distribution in the Chang 7 section.

Summary: Half of all plant species rely on animals for seed dispersal. Defaunation and novel community assembly affect plant adaptation to climate change through migration. Predicting pairwise interactions and dispersal function for fleshy-fruited plants globally can help forecast their assembly and functioning. Mammal and bird defaunation has already reduced the capacity of plants to track climate change by 60% globally, showing a synergy between defaunation and climate change that undermines vegetation resilience.

Summary: This study utilizes a combined statistical and magnetic approach to separate the contribution of different petrofabrics in the magnetic signature, providing insights into the heterogeneities in intraplate shear zones. Through analyzing variations in magnetic properties, the study reveals a strong dependency on distance from thrust faults and strain localization within the shear zone, as well as different responses of ferromagnetic minerals to shearing.

Summary: Tropical ecosystems undergo rapid transformations due to land use and climate change, making it difficult to predict their effects on ecosystem functioning and services. While there are various spatio-temporal data streams available to monitor these changes, limited access and processing hinder a comprehensive understanding of ecosystem functioning in the region.

Summary: The study in northeastern China revealed that topography is the primary environmental factor influencing gully erosion, showing a significant positive correlation with kernel density. Meanwhile, the impact of vegetation, precipitation, and soil texture on gully density decreased successively.

Summary: The study found that mast seeding benefits the seedling recruitment of Armeniaca sibirica by increasing dispersal intensity, supporting the predator dispersal hypothesis. However, high seed abundance may lead to decreased benefits to trees, which could be a result of mismatch between seed and animal abundance.

Summary: The study on Xiaowutai Mountain in the Northern Taihang Mountain Belt, China, showed a significant increase in both the number and area of talus slopes between 2003 and 2017, primarily due to a warming climate. The growth rate of high-roughness talus slopes was higher than that of low-roughness ones, indicating that surface runoff is the primary factor driving talus slope expansion in the area.

Summary: This study investigated the effects of hunting on reproduction and genetic diversity in a puma population. The presence of hunting reduced the age of male breeders and decreased the number of unique fathers siring litters. Hunting also increased relatedness among males and decreased relatedness among females in the population, as well as decreased genetic diversity.

Summary: The study found that in the highly cultivated Po Valley in Europe, different types of natural habitats play a crucial role in maintaining high biodiversity, with tree rows serving as corridors for forest carabid dispersion. Despite similar species richness in different habitats, each had a distinct species assemblage.

Summary: This article presents the research findings of The Meadowcroft Rockshelter in Pennsylvania. While the rockshelter is famous for its pre-Clovis occupation, recent studies have discovered maize macrobotanical remains from higher strata dating back to the 4th century BC based on radiocarbon dating. However, accelerator mass spectrometry dating revealed that these specimens actually originated from the historical use of the rockshelter after AD 1800.

Summary: This article discusses the challenges encountered in using radiocarbon dating, particularly during periods with a reversal/plateau in the C-14 calibration curve. By using the built-in age of wood-charcoal samples, dating ambiguities can be resolved to determine a more accurate date range.

Summary: Despite advancements in techniques and theory, northeastern North American archaeologists still rely on outdated cultural classifications for analysis. This article argues for a shift towards Bayesian analysis of radiocarbon dates to gain a fuller understanding of past human lives. Using a large dataset of radiocarbon dates from late prehistoric sites in the Ohio River basin, the study assesses the variations in settlement plans of contemporaneous villages and their reflection of the needs of the village occupants.

Summary: The sparse occurrence of common bean seeds on village sites in northern New York seems contradictory to the importance of common bean in the agronomic systems and diets of the Northern Iroquoian people. However, the discovery of a large quantity of bean seeds at the ancestral Oneida Diable site provides clues as to when rehydrated/cooked common bean seeds may appear in the archaeological record.

Summary: The Lamoka Lake and Scaccia sites in New York have played significant roles in the development of archaeology, with Lamoka Lake being a representative site for the Archaic period in eastern North America, and Scaccia being the largest Early Woodland Meadowood phase site in New York. New dating methods and Bayesian analyses have refined the ages of these sites, placing Lamoka Lake at 2962-2902 BC and Scaccia at 1049-838 BC.

Summary: According to the archaeological canine surrogacy approach (CSA), the diet of dogs can be used as a proxy for human diets in the absence of human tissue. This study used stable isotope ratios from dog and human bone collagen to reconstruct past human diets, and found that dogs primarily consumed maize, terrestrial animals, low trophic level fish, and even human feces.

Summary: The primary crops in Indigenous agricultural systems in North America before and after European colonization were maize, bean, and squash. Charred maize is the most commonly found in macrobotanical assemblages in northeastern North America, while charred bean and squash seeds are found in lower quantities. Heating experiments have been conducted on maize and bean seeds to determine the temperature range for preservation in archaeological records, but similar studies are lacking for squash seeds.

Summary: Defining and examining democracy in non-Western contexts is challenging because scholars often only think of Western democracy. However, this paper argues that democracy does not exist but rather there are institutions that facilitate democratic governance. The authors propose that Indigenous North America has keystone institutions that promote power distribution and citizen participation, and provide various cases to demonstrate the diversity of democratic keystone institutions. The authors emphasize that the concept of keystone institutions can better understand the emergence and role of democratic governance.

Summary: This study utilizes social network analysis of collar decoration on Iroquoian vessels to analyze signaling practices among ancestral Huron-Wendat communities. Results show that network ties were stronger among populations in adjacent drainages as opposed to within drainage-specific sequences, indicating west-to-east population movement in the sixteenth century.
