Abstract Cryosphere has a global role as a biogeophysical phenomenon. It affects the livelihoods of people inhabiting permafrost areas and is affected by human activity within and outside of the cryosphere’s geographical span. “Frozen Commons (FC) are cryosphere resources and landscapes, defined by snow, ice, permafrost, that are experienced, used, protected and managed by groups of people together. This paper highlights collaboration between herders and scientists aimed at improving the understanding of frozen commons in northern Mongolia, a region of rapid cryosphere transformation. The impact of climate change on Indigenous and pastoralist communities in Mongolia is profound, leading to the damage or loss of frozen commons critical for local livelihoods. Therefore, Indigenous and local knowledge becomes crucial in assessing and predicting the climate-driven dynamics of frozen commons. In 2022, 2023, 2024 a team of permafrost scientists, geographers, and economists conducted interviews in reindeer and cattle herder camps in Khövsgöl Aimag (Province) located in the northern part of Mongolia. Local livelihoods depend not only on cattle, which allows us to examine a variety of animal-environment interactions and impacts on pastoralism. The analysis of interviews indicates that frozen commons is a vital resource for the Khövsgöl communities and hold significant importance in their daily lives. Permafrost plays a key role for herders as it provides water resources for pastures and local rivers, which is critical during dry summers. Ice and snow also have many uses, such as a source of water, winter transport, and the basis of cultural events. As winters become shorter and ice conditions become less predictable, the sustainability and availability of these resources for local people are under threat. In light of these challenges, it is imperative to formulate climate adaptation and mitigation strategies through collaborative efforts that actively involve and respect the perspectives of Indigenous and local people.

Disassembling cattle and enskilling subjectivities: Butchering techniques and the emergence of new colonial subjects in Santiago de Guatemala
When they introduced cattle into Guatemala in the 16th century, Europeans also brought a whole new industry involving ranches, slaughterhouses, and new forms of labor. On the one hand, cattle producers had to treat the animals as intact living organisms requiring care and nurture to maintain and increase the herds. Those animals were grown by the ranchers for specific purposes. In the first place, colonial Mesoamerican cattle were raised to produce hides and leather for intercontinental trade with Spain. The regularized disassembling of the bovine bodies created these new products, but it also had some unintended consequences, namely the generation of new subject positions among the indigenous workers of these facilities. New forms of butchering techniques aimed at extracting animal parts were unlike the indigenous practices of animal hunting and exploitation, which aimed at preserving the physical integrity of the animals’ bodies. The newly introduced techniques that involved the compartmentalization of animal bodies also involved an increased compartmentalization of labor, accompanied by new body techniques and gestures. As the butchers and the tanners became enskilled, their bodies changed and so did their hexis. To operationalize these ideas, technological approaches combined with zooarchaeological (butchery marks), ethnographic, and historical evidence are used to investigate how humans and cattle mutually grew each other’s matter and subjectivities.

Global Positioning Systems (GPSs) can collect tracking data to remotely monitor livestock well-being and pasture use. Supervised machine learning requires behavioral observations of monitored animals to identify changes in behavior, which is labor-intensive. Our goal was to identify animal behaviors automatically without using human observations. We designed a novel framework using unsupervised learning techniques. The framework contains two steps. The first step segments cattle tracking data using state-of-the-art time series segmentation algorithms, and the second step groups segments into clusters and then labels the clusters. To evaluate the applicability of our proposed framework, we utilized GPS tracking data collected from five cows in a 1096 ha rangeland pasture. Cow movement pathways were grouped into six behavior clusters based on velocity (m/min) and distance from water. Again, using velocity, these six clusters were classified into walking, grazing, and resting behaviors. The mean velocity for predicted walking and grazing and resting behavior was 44, 13 and 2 min/min, respectively, which is similar to other research. Predicted diurnal behavior patterns showed two primary grazing bouts during early morning and evening, like in other studies. Our study demonstrates that the proposed two-step framework can use unlabeled GPS tracking data to predict cattle behavior without human observations.more » « less

In many regions of the world, populations of large wildlife have been displaced by livestock, and this may change the functioning of aquatic ecosystems owing to significant differences in the quantity and quality of their dung. We developed a model for estimating loading rates of organic matter (dung) by cattle for comparison with estimated rates for hippopotamus in the Mara River, Kenya. We then conducted a replicated mesocosm experiment to measure ecosystem effects of nutrient and carbon inputs associated with dung from livestock (cattle) versus large wildlife (hippopotamus). Our loading model shows that per capita dung input by cattle is lower than for hippos, but total dung inputs by cattle constitute a significant portion of loading from large herbivores owing to the large numbers of cattle on the landscape. Cattle dung transfers higher amounts of limiting nutrients, major ions and dissolved organic carbon to aquatic ecosystems relative to hippo dung, and gross primary production and microbial biomass were higher in cattle dung treatments than in hippo dung treatments. Our results demonstrate that different forms of animal dung may influence aquatic ecosystems in fundamentally different ways when introduced into aquatic ecosystems as a terrestrially derived resource subsidy.more » « less

Recently expanded estimates for when humans arrived on Madagascar (up to approximately 10 000 years ago) highlight questions about the causes of the island's relatively late megafaunal extinctions (approximately 2000–500 years ago). Introduced domesticated animals could have contributed to extinctions, but the arrival times and past diets of exotic animals are poorly known. To conduct the first explicit test of the potential for competition between introduced livestock and extinct endemic megafauna in southern and western Madagascar, we generated new radiocarbon and stable carbon and nitrogen isotope data from the bone collagen of introduced ungulates (zebu cattle, ovicaprids and bushpigs, n = 66) and endemic megafauna (pygmy hippopotamuses, giant tortoises and elephant birds, n = 68), and combined these data with existing data from endemic megafauna (n = 282, including giant lemurs). Radiocarbon dates confirm that introduced and endemic herbivores briefly overlapped chronologically in this region between 1000 and 800 calibrated years before present (cal BP). Moreover, stable isotope data suggest that goats, tortoises and hippos had broadly similar diets or exploited similar habitats. These data support the potential for both direct and indirect forms of competition between introduced and endemic herbivores. We argue that competition with introduced herbivores, mediated by opportunistic hunting by humans and exacerbated by environmental change, contributed to the late extinction of endemic megafauna on Madagascar.more » « less

Abstract Growing concerns about the global antimicrobial resistance crisis require a better understanding of how antibiotic resistance persists in soil and how antibiotic exposure impacts soil microbial communities. In agroecosystems, these responses are complex because environmental factors may influence how soil microbial communities respond to manure and antibiotic exposure. The study aimed to determine how soil type and moisture alter responses of microbial communities to additions of manure from cattle treated with antibiotics. Soil microcosms were constructed using two soil types at 15, 30, or 45% moisture. Microcosms received biweekly additions of manure from cattle given cephapirin or pirlimycin, antibiotic-free manure, or no manure. While soil type and moisture had the largest effects on microbiome structure, impacts of manure treatments on community structure and individual ARG abundances were observed across varying soil conditions. Activity was also affected, as respiration increased in the cephapirin treatment but decreased with pirlimycin. Manure from cattle antibiotics also increased NH4+and decreased NO3−availability in some scenarios, but the effects were heavily influenced by soil type and moisture. Overall, this work demonstrates that environmental conditions can alter how manure from cattle administered antibiotics impact the soil microbiome. A nuanced approach that considers environmental variability may benefit the long-term management of antibiotic resistance in soil systems.more » « less
