In contrast to fairly good knowledge of dissolved carbon and major elements in great Arctic rivers, seasonally resolved concentrations of many trace elements remain poorly characterized, hindering assessment of the current status and possible future changes in the hydrochemistry of the Eurasian Arctic. To fill this gap, here we present results for a broad suite of trace elements in the largest rivers of the Russian Arctic (Ob, Yenisey, Lena, and Kolyma). For context, we also present results for major elements that are more routinely measured in these rivers. Water samples for this study were collected during an international campaign called PARTNERS from 2004 through 2006. A comparison of element concentrations obtained for Arctic rivers in this study with average concentrations in the world’s rivers shows that most elements in the Arctic rivers are similar to or significantly lower than the world average. The mineral content of the three greatest rivers (Ob, Yenisey, and Lena) varies within a narrow range (from 107 mg/L for Yenisey to 123 mg/L for Ob). The Kolyma’s mineral content is significantly lower (52.4 mg/L). Fluxes of all major and trace elements were calculated using average concentrations and average water discharge for the 2004–2006 period. Based on these flux estimates, specific export (i.e., t/km2/y) for most of the elements was greatest for the Lena, followed by the Yenisey, Ob, and Kolyma in decreasing order. Element pairwise correlation analysis identified several distinct groups of elements depending on their sources and relative mobility in the river water. There was a negative correlation between Fe and DOC concentration in the Ob River, which could be linked to different sources of these components in this river. The annual yields of major and trace elements calculated for each river were generally consistent with values assessed for other mid-size and small rivers of the Eurasian subarctic.

Valuing Difference: Bear Ceremonialism, the Eastern Khanty, and Cultural Variation among Ob-Ugrians
This article draws on a large archive of original video documentation to complement ethnographic literature to provide the first description of modern Eastern Khanty bear ceremonialism and locate it in relation to the traditions of other Ob-Ugrian groups. The comparative analysis of Ob-Ugrian bear ceremonial traditions underscores fundamental differences in the function of such ceremonies, highlights foundational elements of local group identity, and suggests ways in which Ob-Ugrian groups interacted with adjacent populations.

Recent research conducted in southern Sonora, Mexico provides an opportunity to revisit debates about interaction between Mesoamerica and the North American Southwest (NAS). In the borderland between these traditions, communities show few signs of cultural amalgamation, instead exhibiting either an avoidance of overt identity markers or an emphasis on more local connections. This pattern contrasts with most discussions of Mesoamerican influence on the NAS that focus on regionally atypical centers of foreign goods consumption or evidence of foreign religious traditions in distant localities. By recentering on local contexts where cultural amalgamation is expected but minimal, we raise important questions about why more distant groups found Mesoamerican societies to be worthy of emulation. The results suggest researchers should devote equal attention to cases in which distinct identities are erased or suppressed as they do to cases in which social boundaries are maintained or created anew.more » « less

Migliore, Michele (Ed.)The majority of olfaction studies focus on orthonasal stimulation where odors enter via the front nasal cavity, while retronasal olfaction, where odors enter the rear of the nasal cavity during feeding, is understudied. The coding of retronasal odors via coordinated spiking of neurons in the olfactory bulb ( OB ) is largely unknown despite evidence that higher level processing is different than orthonasal. To this end, we use multi-electrode array in vivo recordings of rat OB mitral cells ( MC ) in response to a food odor with both modes of stimulation, and find significant differences in evoked firing rates and spike count covariances (i.e., noise correlations). Differences in spiking activity often have implications for sensory coding, thus we develop a single-compartment biophysical OB model that is able to reproduce key properties of important OB cell types. Prior experiments in olfactory receptor neurons ( ORN ) showed retro stimulation yields slower and spatially smaller ORN inputs than with ortho, yet whether this is consequential for OB activity remains unknown. Indeed with these specifications for ORN inputs, our OB model captures the salient trends in our OB data. We also analyze how first and second order ORN input statistics dynamically transfer to MC spiking statistics with a phenomenological linear-nonlinear filter model, and find that retro inputs result in larger linear filters than ortho inputs. Finally, our models show that the temporal profile of ORN is crucial for capturing our data and is thus a distinguishing feature between ortho and retro stimulation, even at the OB. Using data-driven modeling, we detail how ORN inputs result in differences in OB dynamics and MC spiking statistics. These differences may ultimately shape how ortho and retro odors are coded.more » « less

Did human culture arise through an evolutionary transition in individuality (ETI)? To address this question, we examine the steps of biological ETIs to see how they could apply to the evolution of human culture. For concreteness, we illustrate the ETI stages using a well-studied example, the evolution of multicellularity in the volvocine algae. We then consider how those stages could apply to a cultural transition involving integrated groups of cultural traditions and the hominins that create and transmit traditions. We focus primarily on the early Pleistocene and examine hominin carnivory and the cultural change from Oldowan to Acheulean technology. We use Pan behaviour as an outgroup comparison. We summarize the important similarities and differences we find between ETI stages in the biological and cultural realms. As we are not cultural anthropologists, we may overlook or be mistaken in the processes we associate with each step. We hope that by clearly describing these steps to individuality and illustrating them with cultural principles and processes, other researchers may build upon our initial exercise. Our analysis supports the hypothesis that human culture has undergone an ETI beginning with a Pan -like ancestor, continuing during the Pleistocene, and culminating in modern human culture. This article is part of the theme issue ‘Human socio-cultural evolution in light of evolutionary transitions’.more » « less

Changes in the runoff of rivers flowing into the Arctic Ocean caused by climate changes and increasing anthropogenic load lead to foreseeable transformations of hydrological processes in the mouth areas of the rivers. Climatic, water-balance, and hydrodynamic models were successively applied to evaluate the effect of climatic and anthropogenic changes in the drainage basin of the Ob river estuary on seasonal hydrological processes in the Gulf of Ob. Climate changes along with considerable seasonal redistribution of river runoff in the drainage basin of the Gulf of Ob, mostly due to its increase in winter, were found to cause no significant changes in the seasonal hydrological mouth processes in 1980–2018. Estimates for a period of up to 2050 showed that climate changes under various scenarios will cause an increase in streamf low from the basin, which will reduce the penetration of saltwater into the gulf.more » « less
