Gongye shui chuli, 2021 厌氧生物处理技术因其经济和高效的特点广泛应用于硝基芳烃（NACs）等难降解有机废水的治理。但由于NACs类废水毒性较强且厌氧生物代谢缓慢，限制了其实际应用效果。基于此，综述了3种一体化物化-生物耦合技术（电场、氧化还原介体、零价铁耦合厌氧生物强化技术）在强化NACs还原转化方面的研究进展，包括应用进展、影响因素、强化机制以及后续的研究方向，并进行了总结与比较，以期为NACs类废水强化处理工艺的研发提供依据和参考。

Gongye shui chuli, 2023 许多研究致力于用生物脱氮技术去除污染水体中的氮。微生物固定化是采用物理或化学的方法，将微生物截留在某一特定区域的技术。该技术既可保证功能微生物在适宜条件下快速增殖，使其具有较高的抵御外界不利环境因素的优势，同时可提高功能微生物与本土微生物的竞争力。生物脱氮技术与微生物固定化技术相结合具有很大的应用潜力。综述了几种传统微生物固定化方法和新型微生物固定化方法的分类、原理、优缺点、应用范围及前景。在此基础上，以凝胶包埋法为例，介绍了微生物固定化技术强化生物脱氮的机理，如为微生物提供相应保护 ...

Wildlife Letters, EarlyView.Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons. The species exhibits strong aquatic dependence, favoring deep pools interspaced among riffle‐pool sequences ...

Wildlife Letters, EarlyView.We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Wildlife Letters, EarlyView.The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

Wildlife Letters, EarlyView.We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans
