Brookes, J.D. in OpenAIREThis study highlights how Chinese economic development detrimentally impacted water quality in recent decades and how this has been improved by enormous investment in environmental remediation funded by the Chinese government. To our knowledge, this study is the first to describe the variability of surface water quality in inland waters in China, the affecting drivers behind the changes, and how the government-financed conservation actions have impacted water quality. Water quality was found to be poorest in the North and the Northeast China Plain where there is greater coverage of developed land (cities + cropland), a higher gross domestic product (GDP), and higher population density. There are significant positive relationships between the concentration of the annual mean chemical oxygen demand (COD) and the percentage of developed land use (cities + cropland), GDP, and population density in the individual watersheds (p < 0.001). During the past decade, following Chinese government-financed investments in environmental restoration and reforestation, the water quality of Chinese inland waters has improved markedly, which is particularly evident from the significant and exponentially decreasing GDP-normalized COD and ammonium (NH4+-N) concentrations. It is evident that the increasing GDP in China over the past decade did not occur at the continued expense of its inland water ecosystems. This offers hope for the future, also for other industrializing countries, that with appropriate environmental investments a high GDP can be reached and maintained, while simultaneously preserving inland aquatic ecosystems, particularly through management of sewage discharge.

Jansman, A.J.M. in OpenAIREInsects are a natural component of animal diets. They contain a high amount of digestible protein and fat and are also rich in micronutrients such as copper, iron, magnesium, selenium and zinc, as well as riboflavin, pantothenic acid and biotin. In addition, insects contain bioactive and immunostimulatory constituents such as lauric acid, antimicrobial peptides and chitin. These nutritional and functional properties make insects a promising feed ingredient to replace conventional feed ingredients and as such sustainability in animal production may be improved. In the European Union (EU), since 2017 eight insect species are authorized for aquafeed. Recent relaxation of the EU feed ban rules and animal by-products legislation on September 7, 2021, also allowed the use of insect proteins in poultry and pig diets. Among the authorized insect species, some are more promising for feed purposes as they can be theoretically mass produced. More-over, these species apply the circular economy concept by bioconverting organic substrates, which find minor applications for other purposes. Advances in the development of the European insect industry are often associated with more favourable sustainability potentials of insects, compared to traditional protein sources. For the EU there is a significant overlap in ingredient use in diets for pigs and poultry. Despite multiple studies on economic feasibility, social acceptance and environmental impact, many open questions are left for the industry to deal with. Life Cycle Assessment (LCA), relying on a modular modelling approach to cover the complete spectrum of insect production and processing parameters, is a methodology which can provide viable answers and recommendations on envi-ronmental sustainability performance. For different livestock animal species, the current animal production systems, volumes of feed and composition of conven-tional diets are presented. The digestibility of insect meals and effects of their use on growth performance, product quality and health at different dietary inclusion levels are reviewed. Finally, the contribution of dietary inclusion of insect protein in animal production systems to sustainability is discussed.

Current policies of habitat conservation, recovery, and management are strongly biased in favour of terrestrial systems, being poorly applicable to marine environments. A sound habitat classification, leading to spatially explicit accounts on the distribution of marine habitats and communities, is a prerequisite to identify conservation priorities, based on appropriate methods for assessing habitat sensitivity to human disturbance, aimed at preventing habitat loss. The ten major European marine habitat classifications, recognizing a total of 1121 marine habitats, have been here revised, and their major differences have been formally tested in terms of multivariate dissimilarity. Mediterranean-based classifications resulted rather uniform, their habitats forming a separate cluster from the rest of European ones; these differences might be due to either distinct ecological features, or to divergences in the way habitats are classified. Either too vague or too detailed classifications, leading to cumbersome appreciations of biodiversity at habitat level, fail to provide proper tools for the conservation and management of marine environments. Different species assemblages can inhabit the same habitat type, representing the well-know natural variability that, at large scale, should not affect the appreciation of habitat distribution. Intra-habitat natural variability, in fact, causes a misleading qualitative interpretation of small-scale biodiversity distribution. Mediterranean classifications have been integrated and simplified by identifying habitats according to explicit criteria: level on the shore, type of primary substrate, presence of bioconstructors, presence of habitat formers, presence of ecosystem engineers. The motivating idea is to limit the current emphasis on spatial dominance as the only criteria for the introduction of species, assemblages, and habitats in the lists, towards a clearer recognition of the structural and functional role of biodiversity. The reduction of previous classifications to a list of 94 Mediterranean marine habitat types represents an initial attempt at providing a simple and flexible tool for the evaluation of biodiversity at habitat level, leading to more feasible conservation measures, potentially extendable at European scale.

BOERO, Ferdinando in OpenAIREThe majority of Hydrozoa is represented by not readily noticeable, small species. In recent decades, however, taxonomic knowledge of the group has increased worldwide, with a significant number of investigations focused on the Mediterranean Sea. Over more than two decades, 115 species of hydrozoans were recorded from coastal waters along nearly 300 km of the Salento Peninsula (Apulia, Italy). For each species, records from different collections were merged into single sheets of a general database. For each species, the following information is reported: description, cnidome, biology, occurrence in Salento, worldwide distribution, and bibliography. Descriptions refer to the benthic hydroid stage and, when present, also to the planktonic medusa stage. The 115 species of Hydrozoa, recorded along the Salento coastline, represent 25% of the Mediterranean Hydrozoa fauna (totaling 461 species), and nearly 3% of 3,702 world's known species covered in a recent monograph. Four species are non-indigenous, three of them with invasive behavior (Clytia hummelincki, Clytia linearis, and Eudendrium carneum), and one species now very common (Eudendrium merulum) in Salento. The complete life cycle of Clytia paulensis (Vanhöffen, 1910) is described for the first time.

Coating electroaccretion on galvanized iron and aluminum 1100 under cathodic polarization in artificial and natural seawaterwas investigated through electrochemical tests and optical imaging techniques. Biofilm affects the current density and the morphologies of gas evolution, particularly the maximum size of the gas bubbles and the interaction between gas evolution and calcareous deposit. Coating mineral composition is related to the type of metallic material and can be different according to growth in natural or artificial seawater. On galvanized iron in ASTM and natural seawater at potential -1.2V versus Ag/AgCl. Coatings grown on aluminum 1100 are different from those on galvanized iron. In ASTM seawater, the coating on aluminum 1100 is composed of aluminum oxide and Mg4Al2(OH)14·2H2O; in natural seawater, only of aluminum oxide. On specimens coupled with magnesium anode, the coating does not contain brucite and is composed of aragonite with Mg6Al2(OH)18·4H2O islands.

Understanding the causes of past atmospheric methane (CH4) variability is important for characterizing the relationship between CH4, global climate and terrestrial biogeochemical cycling. Ice core records of atmospheric CH4 contain rapid variations linked to abrupt climate changes of the last glacial period known as Dansgaard-Oeschger (DO) events and Heinrich events (HE)1,2. The drivers of these CH4 variations remain unknown but can be constrained with ice core measurements of the stable isotopic composition of atmospheric CH4, which is sensitive to the strength of different isotopically distinguishable emission categories (microbial, pyrogenic and geologic)3-5. Here we present multi-decadal-scale measurements of δ13C-CH4 and δD-CH4 from the WAIS Divide and Talos Dome ice cores and identify abrupt 1‰ enrichments in δ13C-CH4 synchronous with HE CH4 pulses and 0.5‰ δ13C-CH4 enrichments synchronous with DO CH4 increases. δD-CH4 varied little across the abrupt CH4 changes. Using box models to interpret these isotopic shifts6 and assuming a constant δ13C-CH4 of microbial emissions, we propose that abrupt shifts in tropical rainfall associated with HEs and DO events enhanced 13C-enriched pyrogenic CH4 emissions, and by extension global wildfire extent, by 90-150%. Carbon cycle box modelling experiments7 suggest that the resulting released terrestrial carbon could have caused from one-third to all of the abrupt CO2 increases associated with HEs. These findings suggest that fire regimes and the terrestrial carbon cycle varied contemporaneously and substantially with past abrupt climate changes of the last glacial period.

Recent studies show how genetic data can inform spatial conservation prioritization (SCP), but they focus on metrics of diversity and distinctness derived primarily from neutral genetic data sets. Identifying adaptive genetic markers can provide important information regarding the capacity for populations to adapt to environmental change. Yet, the effect of including metrics based on adaptive genomic data into SCP in comparison to more widely used neutral genetic metrics has not been explored. We used existing genomic data on a commercially exploited species, the giant California sea cucumber (Parastichopus californicus), to perform SCP for the coastal region of British Columbia (BC), Canada. Using a RAD‐seq data set for 717P. californicusindividuals across 24 sampling locations, we identified putatively adaptive (i.e., candidate) single nucleotide polymorphisms (SNPs) based on genotype–environment associations with seafloor temperature. We calculated various metrics for both neutral and candidate SNPs and compared SCP outcomes with independent metrics and combinations of metrics. Priority areas varied depending on whether neutral or candidate SNPs were used and on the specific metric used. For example, targeting sites with a high frequency of warm‐temperature‐associated alleles to support persistence under future warming prioritized areas in the southern coastal region. In contrast, targeting sites with high expected heterozygosity at candidate loci to support persistence under future environmental uncertainty prioritized areas in the north. When combining metrics, all scenarios generated intermediate solutions, protecting sites that span latitudinal and thermal gradients. Our results demonstrate that distinguishing between neutral and adaptive markers can affect conservation solutions and emphasize the importance of defining objectives when choosing among various genomic metrics for SCP.

AbstractAimThe development of approaches to predict the distribution and potential expansion of invasive species is still an open challenge. Here our goal is to improve the modelling procedure for marine invaders by coupling Species Distribution Models (SDMs) with an analysis of their univariate niche dynamics. In particular, we tested for the first time whether choosing model predictors among the stable niche dimensions was effective in improving predictions of invasive species expansion.LocationMediterranean Sea.TaxonDusky spinefoot, Siganus luridus.MethodsWe analysed the univariate niche dynamics for S. luridus across its native and invaded ranges, by applying a standardized framework that allowed the identification of cases of niche stability or shift. We compared inter‐range transferability of SDMs fitted with different combinations of labile or stable predictors. Finally, we evaluated interactions in SDM settings (calibration area, model technique and predictors set) on models’ predictive ability, using independent data from the most recent phase of invasion.ResultsWe detected a pattern of niche stability for several variables, especially salinity and bathymetry, which positively influenced model inter‐ranges transferability: when the models calibrated in the native range include only stable niche axes, predictive ability is improved. We also identified a shift towards lower surface temperatures in the introduced range, which were almost never experienced by the species before invasion. The model calibrated within the combined ranges was the most ecologically congruent. Also, models calibrated in the invaded range allowed a correct prediction of range expansion, with the predicted suitable areas only slightly underestimated.Main conclusionsWe provide the first evidence that using conserved predictors in SDMs improves inter‐range projections of expanding invasive species. Variable selection, calibration area and modelling technique all matter when modelling invasive species, with important interaction effects. We provide guidelines on how to improve SDMs applications in biological invasion research.

Beare, D.J. in OpenAIREPhytoplankton account for approximately 50% of global primary production, form the trophic base of nearly all marine ecosystems, are fundamental in trophic energy transfer and have key roles in climate regulation, carbon sequestration and oxygen production. Boyce et al.1 compiled a chlorophyll index by combining in situ chlorophyll and Secchi disk depth measurements that spanned a more than 100-year time period and showed a decrease in marine phytoplankton biomass of approximately 1% of the global median per year over the past century. Eight decades of data on phytoplankton biomass collected in the North Atlantic by the Continuous Plankton Recorder (CPR) survey2, however, show an increase in an index of chlorophyll (Phytoplankton Colour Index) in both the Northeast and Northwest Atlantic basins3,4,5,6,7 (Fig. 1), and other long-term time series, including the Hawaii Ocean Time-series (HOT)8, the Bermuda Atlantic Time Series (BATS)8 and the California Cooperative Oceanic Fisheries Investigations (CalCOFI)9 also indicate increased phytoplankton biomass over the last 20–50 years. These findings, which were not discussed by Boyce et al.1, are not in accordance with their conclusions and illustrate the importance of using consistent observations when estimating long-term trends.

Abstract Climate change is now evident also in Antarctica, with impacts both on the abiotic and the biotic components of ecosystems, particularly on permafrost, active layer thickness, vegetation, and soil properties. Permafrost ecosystems are recognized to be sensitive to the influences of the changing climate, which may activate, through complex mechanisms, both positive and negative feedbacks relating to CO2 fluxes. For this reason we analysed, through a data set collected over a complete year, the thermal regime of the active layer at four sites with different vegetation (bare ground, lichen vegetation with Usnea aurantiaco-atra, moss vegetation with Sanionia uncinata, grass vegetation with Deschampsia antarctica) but with similar topographic and geomorphological conditions at Signy Island (Maritime Antarctica). Except for the Deschampsia site, the other three sites are the same formerly studied by Chambers in the 1960s. The three sites show significant differences of the mean annual ground surface temperature (MAGST), ranging from − 1.9 (Usnea) to − 2.6 °C (Sanionia). Despite the clear differences in MAGST at the investigated sites, the mean annual ground temperature at 30 cm is virtually identical. Our results confirm that mosses play an important role in cooling the ground. The results of our study allow us to suggest also that the thawing degree days should be used instead of the growing degree days as a more suitable measure of the favourable conditions for the growth of the Antarctic cryptogam vegetation. Comparing our data with those of Chambers [Chambers, M.J.G., 1966b. Investigations on patterned ground at Signy Island, South Orkney Islands: II. Temperature regimes in the active layer. British Antarctic Survey Bulletin, 10: 71–83.], we can stress that the thermal conditions favourable to the frost heave is actually even more limited in depth (30 cm vs 40 cm in Chambers). Moreover, the freeze–thaw days near the surface appeared to be more frequent in the vegetated sites than in the bare ground.
