Bioelectrochemical method with regard to dehalogenation: An evaluation.
Despite bottom trawling being the most widespread, severe disturbance affecting deep-sea environments, it remains uncertain whether recovery is possible once trawling has ceased. Here, we review information regarding the resilience of seamount benthic communities to trawling. We focus on seamounts because benthic communities associated with these features are especially vulnerable to trawling as they are often dominated by emergent, sessile epifauna, and trawling on seamounts can be highly concentrated. We perform a meta-analysis to investigate whether any taxa demonstrate potential for recovery once trawling has ceased. Our findings indicate that mean total abundance can gradually increase after protection measures are placed, although taxa exhibit various responses, from no recovery to intermediate/high recovery, resistance, or signs of early colonisation. We use our results to recommend directions for future research to improve our understanding of the resilience of seamount benthic communities, and thereby inform the management of trawling impacts on these ecosystems.Considering the thermal limits of coastal macroalgae habitats in the South-Eastern Mediterranean, it is important to study the response of the associated meiofauna to better understand the expected feedback of ecosystems to future warming. In this study, we compared benthic foraminiferal assemblages from two common macroalgal habitats, Turf and Coralline algae, based on ecological monitoring of a thermally polluted station representing near future warming, and an undisturbed environment. None of the common local species is confined to a specific algal habitat. This implies that their existence is not threatened by the disappearance of the Coralline algae. However, most likely their community structure will be impacted with coastal warming. Species that are more affiliated with Coralline algae are highly thermally tolerant, thus their proliferation might be reduced with warming. Specifically, the negative response of Coralline algae to warming may limit the contribution of invasive species such as Pararotalia calcariformata.As foundation species, kelp support productive and species rich communities; however, the effects of kelp structure on mobile species within these complex natural systems are often difficult to assess. We used artificial reefs with transplanted kelp to quantify the influence of kelp patch size and density on fish assemblages including the arrival of recruiting cryptobenthic species. Large patches with dense kelp supported the highest abundance, species richness, and diversity of fishes, with the addition of dense kelp tripling biomass and doubling richness. The abundance of recruits in artificial collectors declined with patch size and was halved on reefs with sparse kelp compared to reefs with dense kelp or no kelp. These results highlight the importance of dense kelp cover in facilitating biodiversity and indicate that kelp addition could support the recovery of degraded coastal ecosystems. Kelp also apparently drives complex interactions affecting the recruitment/behaviour of some cryptobenthic species.The purpose of this study was to examine the differential efficacy of aftercare substance use treatments for younger (below 40, n = 107) versus older (40+, n = 114) adults (N = 221), using data from a randomized controlled trial in a community-based substance abuse treatment center. The younger adult sample had a mean age of 28.9 while the older adult sample had a mean age of 48.1. Primary outcomes were rates of abstinence and percent use days at 1-year follow-up. DL-Buthionine-Sulfoximine order Outcomes were compared between standard cognitive behavioral relapse prevention (RP), Mindfulness-Based Relapse Prevention (MBRP), and 12-step-based treatment as usual (TAU). Results showed significant differences by treatment in the older, but not in younger, subsample of participants. Specifically, the older participants in MBRP had significantly higher abstinence rates compared with those in TAU. Further, the older individuals in MBRP had a significantly lower percent of days on which they used compared with those in TAU and RP. Overall, findings suggest that age group may impact aftercare treatment substance use outcomes.Although young men or young adults with mental health disorders are at higher risk to engage in problematic drinking, they typically evince stronger associations between protective behavioral strategies (PBS) and fewer alcohol outcomes. This study aimed to contribute to this line of research by examining the moderating effect of depression, bipolar spectrum disorder, borderline personality disorder and social anxiety disorder on the association between PBS and alcohol outcomes. Participants (N = 4,960; mean age = 25.43) were young men participating in the Cohort Study on Substance Use Risk Factors. Measures of PBS use, typical drinks per week, alcohol-related consequences, depression, bipolar spectrum disorder, borderline personality disorder and social anxiety disorder were used from the second follow-up assessment. Main results indicated that the negative association between PBS and alcohol use was stronger in participants with borderline personality disorder than among those without this disorder. Unexpectedly, in participants with depression, PBS were not significantly associated with alcohol use, whereas they were related to fewer drinks among those without the disorder. Similarly, in participants with bipolar spectrum disorder, the association between PBS and alcohol-related consequences was not significant, whereas PBS were associated with fewer consequences in those without the disorder. Finally, findings indicated that social anxiety disorder did not significantly moderate the associations between PBS and alcohol outcomes. If replicated by future research, these findings imply that PBS-intervention may not equally impact young adults with diverse mental health disorders.The dominant biomedical perspective on addictions has been that they are chronic brain diseases. While we acknowledge that the brains of people with addictions differ from those without, we argue that the "broken brain" model of addiction has important limitations. We propose that a systems-level perspective more effectively captures the integrated architecture of the embodied and situated human mind and brain in relation to the development of addictions. This more dynamic conceptualization places addiction in the broader context of the addicted brain that drives behavior, where the addicted brain is the substrate of the addicted mind, that in turn is situated in a physical and socio-cultural environment. From this perspective, neurorehabilitation should shift from a "broken-brain" to a systems theoretical framework, which includes high-level concepts related to the physical and social environment, motivation, self-image, and the meaning of alternative activities, which in turn will dynamically influence subsequent brain adaptations.
