Summary: This study examines the nonlinear impact of non-pastoral income on livestock herd size in pastoral areas in Inner Mongolia, China. It suggests that non-pastoral income has both substitution and wealth effects on livestock herd size, leading to a U-shaped relationship. Initial increase in non-pastoral income results in decreased herd size due to partial substitution, but continued increase enables additional animal production and may lead to overgrazing.

Summary: This study aimed to quantify the seasonality in cattle proximity to domestic water sources and household compounds, as well as develop a preliminary landscape model of faecal deposition by cattle. Results showed significant differences in home range size, distance travelled from the household, and time spent tethered between seasons, but not in the time spent at domestic water sources or home range overlap with other herds. The preliminary landscape model of faecal deposition by cattle could be further developed to inform interventions for safe separation of livestock and people.

Summary: Warming temperatures due to climate change may affect the distribution and abundance of freshwater fish species, with different species showing varying responses to temperature changes. A study in northern Europe found that increased temperatures led to changes in the catch composition of anadromous salmonids, with Arctic charr decreasing and brown trout increasing in proportion. Atlantic salmon remained stable in relative catch.

Summary: The susceptibility of cervids to Chronic Wasting Disease (CWD) in Norway is modulated by variations in the prion protein gene (PRNP), with different species having different levels of susceptibility. The PRNP genetic data indicate considerable susceptibility to CWD among Norwegian cervids, and suggest that PRNP homozygosity may be a risk factor for the atypical CWD observed in moose. The CWD isolates found in Norwegian cervids differ from those previously found in Canada and USA, indicating potential strain dynamics related to PRNP variability.

Summary: The concentrations of legacy organochlorines and perfluoroalkyl substances in tawny owl eggs in central Norway have shown varying trends over the past few decades. Most legacy OCs and PFOS have not reached a lower threshold with stable background levels, and voluntary elimination of perfluoroalkyl carboxylates has not resulted in declining levels in tawny owls in central Norway.

Summary: The outbreak of COVID-19 has had varying impacts on Norwegian reindeer husbandry and its management system. Reindeer herders experienced little to no impact on their daily work, but faced negative effects on work in corrals, income, and slaughter. Employees in the management system faced challenges in communication, visits, and control. While the government's communication of COVID-19 information and prevention measures satisfied the employees, the herders were dissatisfied.

Summary: This study compared the exposure of organohalogenated contaminants (OHCs) in two avian predator species in different ecosystems. The results showed that the proportional distribution of OHCs and PFASs was similar in the two species. However, the concentrations of PFASs were higher in goldeneye ducks than in tawny owls. The main OC components in goldeneyes were persistent polychlorinated biphenyls (PCBs), while OC-pesticides dominated in tawny owls. Moreover, most OC pesticides and less persistent PCB101 declined in concentration in both species, while PFOS declined in tawny owls but remained stable in goldeneyes.

Summary: Hunter-collected data and samples are used to monitor the population performance of high Arctic reindeer. Skeleton size measurements, such as lower jawbone length and hind-leg length, can serve as good predictors of carcass mass, especially in young age classes. However, the relationships weaken in adults due to skeletal growth ceasing and increased variance in mass with age, potentially caused by annual environmental fluctuations.

Summary: Due to regulations, the deposition of most toxic metals and metalloids in Europe has decreased over the past few decades. However, little is known about the impact of this reduction on exposure levels in terrestrial food webs. This study used tawny owls as biomonitoring species to investigate temporal and spatial trends of exposure to these elements. The results showed a significant decline in toxic elements over time, while beneficial elements exhibited fluctuations but an overall decline. The distance to potential sources of contamination influenced the spatial patterns and temporal trends of element concentrations.

Summary: The balance of resource allocation to life-history traits can have significant consequences for survival, reproduction, and fitness for species in unpredictable environments. Environmental severity, food availability, and population size all influence the allocation of resources in animals. Animals facing extreme resource limitation may allocate resources to body reserves for survival at the cost of reproduction. In contrast, animals in relatively benign landscapes may allocate resources to reproduction. The theory of risk-sensitive allocation suggests that animals may shift resource allocation to building capital over reproduction when exposed to unprecedented or life-threatening conditions. This study on mule deer found that a life-threatening winter and a reduction in population abundance influenced how animals acquired and allocated energy to survival. Fat accumulation was influenced by per capita precipitation and the reduction in population abundance. Fat accrual in preparation for winter was associated with shifts in risk tolerance, supporting the idea of risk-sensitive allocation as an essential adaptation for animals in rapidly changing landscapes.

Summary: The evolution of political complexity has always been an important issue in humanities and social sciences. Despite the pervasiveness of social inequality in contemporary societies, livestock, as the main source of wealth, does not limit the development of inequalities in pastoral societies. A study on reindeer herding in Norway shows that while there are improvements in wealth inequality, rank differences still persist over time. This indicates that pastoral wealth inequality follows a similar pattern to other forms of wealth, where high earners can accumulate more wealth, leading to significant wealth inequality.

Summary: The asymmetric grandparental investment in humans may be explained by the paternity uncertainty hypothesis. However, the specific mechanisms leading to grandparental bias in investment in grandchildren are unclear. A study found that comments on resemblance of children occurred more frequently among siblings after both became parents, suggesting that resemblance descriptions may become more important after both siblings have children. Furthermore, sisters were more proactive in commenting on resemblance of their brothers' child, potentially influencing alloparents' perception of resemblance and influencing alloparental investments.

Summary: This study analyzes the reproductive output of the northern Lesser Black-backed Gull in relation to the occurrence of breeding Ravens. The study finds that the breeding and fledglings brought by Ravens result in a high nest predation rate and a decline in the number of gulls. It also finds that the number of gulls does not decline in neighboring colonies without Ravens.
