Effect of culling on individual badger Meles meles behaviour
Culling wildlife as a form of disease management can have unexpected and sometimes counterproductive outcomes. In the UK, badgers Meles meles are culled in efforts to reduce badger‐to‐cattle transmission of Mycobacterium bovis, the causative agent of bovine tuberculosis (TB). However, culling has previously been associated with both increased and decreased incidence of M. bovis infection in cattle. The adverse effects of culling have been linked to cull‐induced changes in badger ranging, but such changes are not well‐documented at the individual level. Using GPS‐collars, we characterized individual badger behaviour within an area subjected to widespread industry‐led culling, comparing it with the same area before culling and with three unculled areas. Culling was associated with a 61% increase (95% CI 27%–103%) in monthly home range size, a 39% increase (95% CI 28%–51%) in nightly maximum distance from the sett, and a 17% increase (95% CI 11%–24%) in displacement between successive GPS‐collar locations recorded at 20‐min intervals. Despite travelling further, we found a 91.2 min (95% CI 67.1–115.3 min) reduction in the nightly activity time of individual badgers associated with culling. These changes became apparent while culls were ongoing and persisted after culling ended. Expanded ranging in culled areas was associated with individual badgers visiting 45% (95% CI 15%–80%) more fields each month, suggesting that surviving individuals had the opportunity to contact more cattle. Moreover, surviving badgers showed a 19.9‐fold increase (95% CI 10.8–36.4‐fold increase) in the odds of trespassing into neighbouring group territories, increasing opportunities for intergroup contact. Synthesis and applications. Badger culling was associated with behavioural changes among surviving badgers which potentially increased opportunities for both badger‐to‐badger and badger‐to‐cattle transmission of Mycobacterium bovis. Furthermore, by reducing the time badgers spent active, culling may have reduced badgers' accessibility to shooters, potentially undermining subsequent population control efforts. Our results specifically illustrate the challenges posed by badger behaviour to cull‐based TB control strategies and furthermore, they highlight the negative impacts culling can have on integrated disease control strategies.

Multi-objective optimization and algorithmic evaluation for EMS in a HRES integrating PV, wind, and backup storage
This manuscript focuses on optimizing a Hybrid Renewable Energy System (HRES) that integrates photovoltaic (PV) panels, wind turbines (WT), and various energy storage systems (ESS), including batteries, supercapacitors (SCs), and hydrogen storage. The system uses a multi-objective optimization strategy to balance power management, aiming to minimize costs and reduce the likelihood of loss of power supply probability (LPSP). Seven different algorithms are assessed to identify the most efficient one for achieving these objectives, with the goal of selecting the algorithm that best balances cost efficiency and system performance. The system is assessed across three operational scenarios: (1) when energy supply meets demand with help from backup systems, (2) when demand exceeds supply and energy storage systems are depleted, and (3) when energy generation surpasses demand and storage systems are full. The HBA-based optimization effectively manages energy flow and storage, ensuring grid stability and minimizing overcharging risks. This system offers a reliable and sustainable power supply for isolated microgrids, effectively managing energy production, storage, and distribution. The research sets a new benchmark for future studies in decentralized energy systems, particularly in balancing technical efficiency and economic feasibility.

Contact Zone of European (Meles meles Linnaeus, 1758) and Asian (M. leucurus Hodgson, 1847) Badgers (Mustelidae, Mammalia) in the Right- and Left-Bank Districts of the Saratov Region
The DNA studies of badgers (
Meles
sp.) from the right-bank and left-bank areas of the Volga River in the Saratov region are described. Asian badgers (
Meles leucurus
Hodgson, 1847) inhabit the Left Bank of the Volga river in the Saratov region, while European badgers (
M. meles
Linnaeus, 1758) inhabit the Volga Right-Bank districts of the region; however, Asian badgers have been found in Khvalynsky district of the Saratov region in addition to the European badger. Despite the sufficient number of publications devoted to the Asiatic badger distribution in the Vyatka–Kama region and the Volga region and the studies devoted to the development of systematics of the genus
Meles
in Russia, the question of the boundaries of the ranges of European and Asiatic badgers and the zones of their sympatry (parapatry) in the Volga–Kama region has not been fully investigated to date. Our work is devoted to the study of this question. The analysis of biological material that we have collected has shown that all five of the studied badger individuals from the Saratov Volga region phenotypically look like Asian badgers; however, DNA analysis showed that only two of them were
M. leucurus
and other three were heterozygous individuals carrying genes from both species and were identified as hybrids. The remaining 29 individuals were captured in the right-bank areas of the region. Samples were taken from badger individuals from the northern to southern borders of the region in the areas located along the Volga River on the Volga Upland and in the Oka–Don Plain. Among them, one individual from Khvalynsky district turned out to be an Asian badger, one individual from Krasnoarmeysky district was a hybrid of these two species, and three individuals, one from Tatishchevsky, the second from Volsky and the third from Khvalynsky districts showed introgression of Asian badger genes into the genotype of European badger. Thus, we have managed to find out that, at this stage of the development of the climatic cycle phase in the Lower Volga Region characterized by warming winters, the Volga River, with its two reservoirs within the Saratov region, is not an absolute zoogeographical boundary and badgers whose species are characterized by winter sleep can under certain conditions overcome, most likely on ice, both the river itself and the lake parts of the Volgograd and Saratov reservoirs. According to the revealed introgression in some individuals from different areas on the Volga Upland of the right bank of the Saratov region, it can be assumed that such traveling across the Volga River took place earlier, possibly before its flow was regulated by dams.

Nest predators of Chinese Grouse ( Tetrastes sewerzowi ) at Lianhuashan, Gansu, China
Predation is the most important cause of nest failure in the Chinese Grouse (Tetrastes sewerzowi). However, no studies have been conducted to document the nest predators responsible for nest predation events. During 2012-2016. we monitored 17 nests using infrared video cameras to identify nest predators of Chinese Grouse. Six nests were preyed upon during the incubation period. We successfully identified the predators responsible for 5 depredated nests: Asian badger (Meles leucurus), hog badger (Arctonyx collaris), and Blue Eared Pheasant (Crossoptilon auritum). The Asian badger was responsible for 3 of these nest predation events. We recorded Siberian chipmunk (Tamias sibiricus) and an unidentified rodent species attempting to prey upon grouse eggs, but none of them were successful. Received X March 2022. Accepted 24 September 2022. Key words: Asian badger. Blue Eared Pheasant, hog badger, infrared video camera.

Why indigenous literatures matter
Part survey of the field of Indigenous literary studies, part cultural history, and part literary polemic, Why Indigenous Literatures Matter asserts the vital significance of literary expression to the political, creative, and intellectual efforts of Indigenous peoples today. In considering the connections between literature and lived experience, this book contemplates four key questions at the heart of Indigenous kinship traditions: How do we learn to be human? How do we become good relatives? How do we become good ancestors? How do we learn to live together? Blending personal narrative and broader historical and cultural analysis with close readings of key creative and critical texts, Justice argues that Indigenous writers engage with these questions in part to challenge settler-colonial policies and practices that have targeted Indigenous connections to land, history, family, and self. More importantly, Indigenous writers imaginatively engage the many ways that communities and individuals have sought to nurture these relationships and project them into the future. This provocative volume challenges readers to critically consider and rethink their assumptions about Indigenous literature, history, and politics while never forgetting the emotional connections of our shared humanity and the power of story to effect personal and social change. Written with a generalist reader firmly in mind, but addressing issues of interest to specialists in the field, this book welcomes new audiences to Indigenous literary studies while offering more seasoned readers a renewed appreciation for these transformative literary traditions. Awarded the NAISA Award Best Subsequent Book, 2018, PROSE Award, 2019, and shortlisted for ACQL Gabrielle Roy Prize for Literary Criticism, 2018.
