Furthermore, more than 10% of the observed deep gorgonian colonies were entangled by lost longlines, indicating the detrimental effects of this fishing gear on benthic habitats. The discovery of new litter hotspots and the evaluation of how deep-sea species interact with litter contribute to increasing the knowledge about litter distribution and its effects on the deep ecosystem of the Mediterranean basin. All the observations recorded in this study showed substantial and irreversible changes in the deep and remote areas of marine environments, and these changes were found to be caused by humans. Our findings further stress the need for urgent and specific measures for the management of deep-sea pollution and the reduction of litter inputs in the environment.The 'Karakoram Anomaly' is termed as the stability or anomalous growth of glaciers in the central Karakoram, in contrast to the retreat of glaciers in other nearby mountainous ranges of Himalayas and other mountainous ranges of the world. It remains an intriguing scientific question to the researchers. An attempt is made to provide mechanisms leading to such a process and thus 'affirming' it. In view of this, meteorological and cryospheric processes, viz., glacial-atmosphere coupled interactions in tandem with temperature-moisture interactions and radiative balance- on glaciated regions are simultaneously argued over the Karakoram and the adjacent Ladakh. Ladakh is deliberately chosen to compare the weaknesses, lacuna and gaps in the observations/reanalyzes- so that similar forcings are investigated over both regions. It is important to mention that both regions are data sparse. Findings show that geographical and elevation positioning of the Karakoram makes its environmental conditions conducive for glacier stability and/or growth which otherwise is not the case in the Ladakh region. Indian winter monsoon, western disturbances (WDs) embedded within upper level subtropical westerly jet moving eastwards, provides higher moisture incursion which in association with lowered lifting condensation level dumps higher moisture/mass over Karakoram than Ladakh. In addition, role of 2 m surface (T2m) and skin temperature (Ts) is one of the leading driving mechanisms. Difference (T2m-Ts) illustrates inversion which provides stable atmosphere leading to dump all the available moisture/mass over Karakoram, which is contrary over Ladakh.River floodplains are spatially diverse ecosystems that respond quickly to flow variations and disturbance. However, it remains unclear how flow alteration and hydrological disturbance impacts the structure and biodiversity of complex microbial communities in these ecosystems. Here, we examined the spatial and seasonal dynamics of microbial communities in aquatic (benthic) and terrestrial habitats of three hydrologically contrasting (natural flow, residual flow, hydropeaking flow) floodplain systems. Microbial communities (alpha and beta diversity) differed more among floodplain habitats than between riverine floodplains. Microbial communities in all systems displayed congruent seasonal effects. In the residual and hydropeaking systems, an experimental flood was released from a reservoir to mimic a natural high flow event causing hydromorphological disturbance. The experimental flood caused a temporary shift in microbial communities by releasing microbes from the reservoir as well as redistributing communities among floodplain habitats. The flood-mediated shift in community structures had only a transient impact as pelagic bacteria did not persist within floodplain habitats over time after the flood. More frequent pulse disturbances might lead to an alternate structure of bacterial communities in floodplains over time.Excess sludge contains large amounts of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs), posing a risk for human health. However, most current studies usually ignored their abundance and removal in excess sludge. Ther
