“…Based on the positioning of this logical relationship, a preliminary inference is made: AQI monthly mean is correlated with conventional meteorological factors. Using the bivariate analysis function in SPSS software, the correlation between AQI monthly mean and different conventional meteorological factors is tested respectively (see Table 1 for the results) so as to fit the optimal curve equation [ 11 , 12 ].…”

In order to further improve the effectiveness of environmental pollution control and improve the quality of the atmospheric ecological environment, this article discusses regional environmental pollution control from the perspective of sociological theories and methods. Therefore, the article starts with the characteristics of environmental air pollution, combined with linear regression analysis and PSR model principal component analysis, focuses on the impact factors of environmental pollution, and concludes that the weights of pressure layer, state layer, and response layer for the impact of environmental state are 0.4824, 0.261, and 0.1207, respectively. On this basis, from the perspective of social, collaborative governance, and public management, this article focuses on the political measures of environmental pollution.

“…It is notable that the studied marina sediment largely exceeds north American standards of sediment quality for Chrysene, Fluorene, Fluoranthene and Phenanthrene (PAH) as well as for total PCBs, with a 50% probability of toxicity on model amphipods if they were exposed to the sediment (CCME 1999;US EPA 2005). On the contrary MTE pollution, even if above some of these sediment quality guidelines, falls within quality categories described as good or moderate for Cu and Zn as proposed in (Guerra-García et al 2021). Despite the significant effect of location variability on C. intestinalis as shown by the Log-Rank test, none of the contaminants varying significantly between locations could explain the survival profile of this species in the Cox models.…”

Alien vs. predator: influence of environmental variability and predation on the survival of ascidian recruits of a native and alien species

et al. 2022

Drivers of successful introduction of exotic species remain a major headline in marine invasion biology. We ran two experiments aiming to assess factors influencing recruits' survival of one native and one alien ascidian species. A feeding experiment allowed us to monitor microscale variation of generalist fish predation, which varied significantly within a marina. We also monitored the in-situ survival of lab-grown ascidians at three locations within the marina, half with predator cage exclusion. The survival of the native Ciona intestinalis was conjointly highly influenced by location and caging. We were able to identify a link between predation intensity exerted by mobile generalist macropredators and C. intestinalis survival, but none of the measured contaminants accounted for site variability of survival. The non-indigenous Styela clava had significant higher survival and biomass when uncaged, suggesting a positive effect of predation for this species. The natural in situ recruits of C. intestinalis showed higher biomass when caged and may have competed with lab-grown S. clava. Our results suggest that generalist fish predation may play a crucial role in the success of non-indigenous species due to facilitation through competitive release.

“…All the selected marinas are recreational marinas with leisure activities, and all have wood floating pontoons with lateral floating structures made of plastic, where the samples were collected. Details for these marinas (map, surface, number of births and population density) are included in Guerra-García et al (2021). Three different pontoons were haphazardly selected in each marina.…”

“…For example, they show wide oscillations of temperature and salinity, and higher pollution levels than nearby natural environments (Arenas et al, 2006;Bax et al, 2003). Previous environmental studies conducted in marinas have highlighted the relevant role of heavy metals, especially copper from antifouling paint, as one of the most harmful stressors for marine biota (Amara et al, 2018;Guerra-García et al, 2021). The great amount of submerged artificial surfaces within marinas, such as docks, pilings, pontoons, and buoys, allows for the establishment of many sessile organisms, which could act as basibiont species to other organisms (Minchin, 2012).…”

Influence of environmental factors and sessile biota on vagile epibionts: The case of amphipods in marinas across a regional scale

Marinas are highly anthropized environments, with singular ecological characteristics. In the present study the spatial variability of the amphipod assemblage associated to floating pontoons was analyzed. Moreover, the influence of the environmental data and the sessile biota on the amphipod assemblage structure were assessed. Six marinas were selected along the Southern Iberian Peninsula, three in the Atlantic and three in the Mediterranean, and three floating pontoons were sampled at each marina. Four-teen amphipod species were identified, most of them corresponded to detritivores and generalist species. Statistical analyses considering amphipod composition and abundance did not show significant differences between the Atlantic and the Mediterranean, but there were significant differences among marinas. Copper had a significant correlation with the amphipod assemblage. The sessile species Bugula neritina and Ellisolandia elongata also showed a significant influence on the spatial patterns of the amphipod assemblages. Therefore, environmental conditions and sessile composition seem to affect, simultaneously, the spatial variability of amphipod assemblage associated to floating pontoons in marinas. Both factors are key to understand the singularity of marinas. This fact should be taken into consideration to prevent the use of a single management program in these environments.
