The presence and function in several Hohokam sites of controversial objects, currently described as handstones or neflintw-r6mpw crushers, remains an unsolved matter.Their morphology recalls similar Mesoamerican pieces, the manoplas, generally considered to be related to the ballgame.The identification of ballcourts in Hohokam sites has long been a
The discourse of educational philosophy has gradually shifted over years from pedagogy to andragogy to heutagogy.In pedagogy, what is learnt, and how, is both determined and directed by the teacher; in andragogy, it is determined by the teacher and directed by the learner; in heutagogy, both determination and direction shift to the learner (Blashke
The Tapejarinae are edentulous pterosaurs that are relatively common in Cretaceous continental deposits in South America, North Africa, Europe, and China (mostly Early Cretaceous).The Chinese Jiufotang Formation is particularly rich in tapejarine specimens, having yielded over 10 described specimens and dozens of undescribed ones.For the Jiufotang
Morphological traits, such as size and shape, may reflect a combination of ecological and evolutionary responses by organisms.Ants have been used to evaluate the relationship between the environment and species coexistence and morphology.In the present study, we analyzed the morphology of workers of Gnamptogenys striatula Mayr in different landscap
Abstract Background Inoculation of arbuscular mycorrhizal (AM) fungi has the potential to alleviate salt stress in host plants through the mitigation click here of ionic imbalance.However, inoculation effects vary, and the underlying mechanisms remain unclear.Two maize genotypes (JD52, salt-tolerant with large root system, and FSY1, salt-sensitive
