The COVID-19 pandemic has caused an unprecedented disruption to the lives of American Indian (AI) adolescents. While reservation-area AI youth already have a higher risk of substance use (SU) compared to their non-AI peers, COVID-19 stressors likely exacerbated this risk. However, COVID-19-specific and general resilience factors may have buffered against increased SU over the course of the pandemic. Using a person-centered, ecosystemic framework of resilience, we used latent profile analysis to identify ecosystemic resilience profiles indicated by general and COVID-19-specific risk and resilience factors, then examined inter-profile changes in alcohol and cannabis use after the onset of the COVID-19 pandemic from the spring of 2020 to the spring of 2021. The sample was 2218 reservation-area AI adolescents (7-12th grade; schools = 20; = 15, = 1.7; 52% female). Four profiles emerged: Average Risk and Resilience, High Resilience, Low Resilience, and High Risk. Adolescents with a High-Risk profile demonstrated increases in alcohol and cannabis use, while High Resilience youth demonstrated decreases. These findings support the hypothesized COVID-19-specific ecosystemic resilience profiles and the application of a person-centered ecosystemic framework to identify which AI adolescents are most likely to experience substance use changes during a life-altering crisis like COVID-19.

The inclusion of microalgae in functional fish diets has a notable impact on the welfare, metabolism and physiology of the organism. The microbial communities associated with the fish are directly influenced by the host's diet, and further understanding the impact on mucosal microbiota is needed. This study aimed to analyze the microbiota associated with the skin and gills of Sparus aurata fed a diet containing 10% microalgae.

The mechanisms underlying the impact of probiotic supplementation on health remain largely elusive. While previous studies primarily focus on the discovery of novel bioactive bacteria and alterations in the microbiome environment to explain potential probiotic effects, our research delves into the role of living Lactiplantibacillus (formerly known as Lactobacillus) and their conditioned media, highlighting that only the former, not dead bacteria, enhance the healthspan of Caenorhabditis elegans (C. elegans).

The relationship between intra-specific and inter-specific patterns and processes over evolutionary time is key to ecological investigations. We examine this relationship taking an approach of focussing on the association between vegetation and floristic classifications, summaries of inter-specific processes, and intra-specific genetic structuring. Applying an innovative, multispecies, and standardised population genomic approach, we test the relationship between vegetation mapping schemes and structuring of genetic variation across a large, environmentally heterogenous region in eastern Australia.

Climate change has significantly altered fish population dynamics and marine ecosystems worldwide, resulting in multiple ecological, economic and social risks for sustainable fisheries. As a hotspot of global warming, China is anticipated to face with extensive climate-driven changes in marine fisheries and ecosystems, but a clear and adaptative management strategy has not been established. In this study, we assessed the climate adaptiveness of current fisheries management and alternative strategies with diverse management priorities.

Land use change represents a significant environmental transformation on a global scale, profoundly impacting natural ecosystems. The conversion of rangelands into urban parks can adversely affect soil characteristics and biodiversity. This transformation may lead to alterations in soil properties and invertebrate communities, subsequently influencing ecosystem functioning and resilience.
