Abstract

From the beginning of March 2020 and for the following two and half months, many European countries comprising Italy have been forced into an unprecedented lockdown, allowing only the opening of essential economic activities needed to address the problems created by the pandemic (e.g. sanitary, food provision). Like many sectors of the Italian economy, aquaculture has also slowed down due to the ongoing emergency and the consequent closure of business. In our study we provided a ‘snapshot’ of the socio-economic effects of the lockdown on the aquaculture sector in Italy, immediately following the adoption of the COVID-19 restrictions as they were perceived by the workers. Although it was surveyed for a short-time period, differences in perception have been detected both in relation to the type of aquaculture as well as to the geographic locations where farms were placed, partially reflecting the economic gaps already existing within the northern and the southern part of the country before the lockdown.

105. Thermal adaptation and physiological responses to environmental stress in tunicates

Abstract

Understanding the multifaceted nature of environmental fluctuations is crucial to predicting the physiological adjustments utilised by organisms in resisting or adapting to changes over time. Here we investigate the effects of 2 environmental stressors on tunicates, whose fitness can have important repercussions on the quality of habitat. Specifically, we report respiration rate (RR), clearance rate (CR), and assimilation efficiency (AE) of the ascidian Styela plicata in response to a range of temperatures and varying food availability. Temperature-dependent RR was observed only within a portion of the thermal window of the species. Significant differences in clearance rates were detected among organisms fed with varying algal concentrations, while no significant influence of food concentrations on AE was observed. This plasticity of the physiological rates and the development of ubiquitous mechanisms such as temperature-insensitive aerobic metabolism suggest a competitive advantage of this group. Such knowledge may allow for more accurate predictions of the physiological and evolutionary mechanisms driving current and future distribution of this species.

Abstract

Simple Summary: The potential risks posed by microplastics is fully recognised by the scientific community. Because of the multiple pathways that allow microplastics to reach aquatic ecosystems, researchers have focused their work on the ingestion and impact of microplastics on aquatic organisms. However, the main mechanisms through which microplastics shape ecological responses at different levels in the ecological hierarchy remain understudied, and a high degree of data fragmentation exists in the literature. Functional traits, having indirect effects on the three components of individual fitness: growth, reproduction, and survival, represent the main door through which anthropogenic disturbance can enter, impacting the ecological hierarchy, community structure and composition, and ecosystems' features. In light of this, this meta-analysis aims at using data available in the literature to understand and assess how the impacts from microplastics spread across the ecological hierarchy, from the individual to the ecosystem level, and how and if microplastics pollution is negatively affecting biodiversity, ecosystem functioning, and the provision of ecosystem goods and services. Developing trait-based indicators represents a useful step to investigate the impacts of microplastics on ecosystems, and at the same time, could be used to guide policy makers in the development of adequate management plans capable of safeguarding ecosystems, together with the valuable goods and services they offer. Microplastics represent an ever-increasing threat to aquatic organisms. We merged data from two global scale meta-analyses investigating the effect of microplastics on benthic organisms' and fishes' functional traits. Results were compared, allowing differences related to vertebrate and invertebrate habitat, life stage, trophic level, and experimental design to be explored. Functional traits of aquatic organisms were negatively affected. Metabolism, growth, and reproduction of benthic organisms were impacted, and fish behaviour was significantly affected. Responses differed by trophic level, suggesting negative effects on trophic interactions and energy transfer through the trophic web. The experimental design was found to have the most significant impact on results. As microplastics impact an organism's performance, this causes indirect repercussions further up the ecological hierarchy on the ecosystem's stability and functioning, and its associated goods and services are at risk. Standardized methods to generate salient targets and indicators are urgently needed to better inform policy makers and guide mitigation plans. [ABSTRACT FROM AUTHOR]
