Gomphonema alavariense sp. nov. is a new freshwater diatom described in Portugal from phytobenthos samples in an urban pond located in Aveiro (Portugal). This new diatom is illustrated and discussed based on different samples collected in July–August 2017 from Santo António Park pond in the city centre. This taxon was compared with other Gomphonema taxa and the morphological features are documented through light and scanning electron micrographs. Gomphonema alavariense sp. nov. is characterized by showing solitary cells, rhombic-lanceolate to lanceolate valves with rounded apices, a narrow, linear axial area, and slightly asymmetrical central area. This taxon may be confused with G. affine var. rhombicum in terms of length, striae density and outline. Gomphonema alavariense sp. nov. was present in freshwater with low dissolved oxygen concentrations, high conductivity, neutral to slightly alkaline pH and high nitrate concentrations.

Background: Due to their isolation, islands offer excellent areas for the study of distribution of benthic diatoms. On the other hand, diatoms bearing canal raphe have received less attention compared to other groups of diatoms such as Navicula, Pinnularia or Amphora. Questions: Is it possible that thermal springs on islands offer a refuge for infrequent diatom species? Studied species: Platichthys furnensis C. Delgado, V. Gonçalves & S.F.P. Almeida sp. nov. Study site and dates: The species here described was collected in the epilithon of a thermal spring in São Miguel Island (Azores Archipelago, Portugal) in September 2015. Methods: This new taxon was compared to other diatom species of the genera Nitzschia, Tryblionella, Entomoneis and Hantzschia and to the other species of the genus Platichthys. The morphology is documented by light and scanning electron images and discussed in detail. Results: Platichthys furnensis was found in a thermal pool, a similar habitat to the one where P. krammeri type was collected in Chile in 1940. P. furnensis has many structures that are characteristic of the recently described genus Platichthys, including raised canal raphe and fibulae, compressed valve face, steep valve face and numerous open copulae. Conclusions: The description of the new taxon is interesting because it is the first species within Platichthys to be described from the Northern Hemisphere.

A large number of diatom-based classification systems have been developed worldwide in recent years. These new systems, together with the oldest, emerged on the need to assess the water quality of rivers, but knowledge on possible divergences resulting from their simultaneous application within a territory is limited. This study aimed to compare the ecological status classification provided by conceptually different methodological approaches, of use or potential use within the same region. 402 monitoring samples were collected from Atlantic siliceous streams (NW-Iberian Peninsula) and temporary Mediterranean streams (Balearic Islands, Spain). Two multimetric indices specifically developed for these areas (MDIAT and DIATMIB, respectively) were calculated, as well as the Specific Polluosensitivity Index (IPS). Multimetric indices were more sensitive methods at diagnosing degradation than IPS since they took directly account of abundance (i.e. chlorophyll a in DIATMIB) or indirectly by its proved inverse relationship with Chl a (MDIAT), together with their use of the regional reference diatom community. Alteration gradients were identified in both studied regions based on the distribution of diatoms, with the first axis of distance-based redundancy analyses (dbRDA) being related to nutrient enrichment and organic loads. Threshold Indicator Taxa ANalysis (TITAN) performed on diatoms sampled along environmental (dbRDA axis 1 and phosphate) and biological gradients (as Ecological Quality Ratio scores of classifications), pointed to lower than current Good/Moderate boundaries for phosphate maximum values (e.g. 22.5 and 71.6 μg L−1 for Galicia and the Balearic Islands, respectively) as well as for higher Good/Moderate boundaries for the MDIAT and IPS classifications. A ‘transition group’ of species was classified as sensitive or as tolerant depending on the regional nutrients range. Findings of the present study highlight the need to perform auto-ecological studies to increase the knowledge on regional diatoms and their optimal survival ranges across regions prior to adopt other non-regional diatom indices.

Microbial biofilms can be key mediators for settlement of macrofoulers. The present study examines the coupled effects of microbial biofilms and local environmental conditions on the composition, structure and functioning of macrofouling assemblages. Settlement of invertebrates over a gradient of human-impacted sites was investigated on local biofilms and on biofilms developed in marine protected areas (MPAs). Special attention was given to the presence of non-indigenous species (NIS), a global problem that can cause important impacts on local assemblages. In general, the formation of macrofouling assemblages was influenced by the identity of the biofilm. However, these relationships varied across levels of anthropogenic pressure, possibly influenced by environmental conditions and the propagule pressure locally available. While the NIS Watersipora subatra seemed to be inhibited by the biofilm developed in the MPA, Diplosoma cf. listerianum seemed to be attracted by biofilm developed in the MPA only under mid anthropogenic pressure. The obtained information is critical for marine environmental management, urgently needed for the establishment of prevention and control mechanisms to minimize the settlement of NIS and mitigate their threats.

Karst ecosystems are considered as priority environments for the protection of biodiversity on a global scale. This study provides a first comparative analysis of epilithic diatom flora from karst springs in two Mediterranean geographic areas (Spain and Italy) with contrasting characteristics (islands vs mainland). We investigated twenty-three springs with different anthropogenic impact levels once in the winter season between 2007 and 2017 (N = 23). A total of 176 diatom taxa (56 genera) were found of which 101 (44 genera) were observed in single sites. A general good biotic integrity was revealed by structural indices (species richness, diversity and evenness). However, crenophilous species were generally present and abundant in less impacted springs. Comparing islands and mainland, significant differences were found in species composition and diversity (H’) based on multivariate analyses (global R = 0.610; p = 0.001) and t-test (t = 2.304; p = 0.031). Discharge and Cl− were the most significant variables in determining diatom assemblages. Our results confirm the role of springs as multiple ecotones and refuges for rare species and suggest that the geographic insularity may be an important factor in maintaining diatom biodiversity.

New multi-proxy analyses were performed on two sedimentary sections from shallow marine ecosystems of Ría de Vigo (NW Iberia) to study the effects of the MIS-3 and early Holocene environmental variability. High-resolution data (microfossils, sedimentary facies, and geochemistry) allowed performing a comprehensive reconstruction of the main environmental changes (climate, vegetation, hydrology and sea level) that occurred during part of the MIS-3 period (57.0–38.8 cal ka BP) and the early Holocene (11.2–7.0 cal ka BP). The chronology is supported by isotopic dating and the correlation of pollen data with other regional palaeo-climatic records. Several phases characterised by increasing pollen representation of deciduous Quercus alternate with others marked by increasing representation of heliophytes that may reflect the succession of Interstadials (GI) and Stadials (GS) described in Greenland ice cores. In addition, dinoflagellate cysts and diatoms reflect conditions in the marine environment (SST and productivity). New palynological data confirms that coastal ecosystems of Atlantic Iberia were sensitive to the main climatic oscillations affecting the North Atlantic. It also suggests that pinewoods, juniper communities and mesophilous deciduous forests with Carpinus betulus L. (which shows exceptionally high pollen abundances for the MIS-3) persisted in the surroundings of Ría de Vigo until ~7500 a BP. For the first time in this region, we describe the effects of an abrupt episode of cooling that may correspond to Bond cycle 7 (10.5 ka event).

In this study we developed a predictive diatom-based model to assess the ecological status of streams and rivers of Northern Spain. Diatom samples were collected with standard protocols over stones from 676 sites distributed along existing environmental conditions across Northern Spain, during seven years between 2002 and 2008 (n = 1056 samples). This dataset included a network of 91 reference sites selected by using criteria that confirmed the absence of relevant human pressures according WFD. A multinomial logistic regression using GAAC cluster-derived reference sites group as response variable was performed. The independent variables included obligatory typology factors (WFD System A typology descriptors), and other optional typology B descriptors were included in the model performed on a forward stepwise procedure. The Ecological Quality Ratios (EQRs) were obtained by dividing the observed similarity between the diatoms composition in each sample by the expected median similarity of each type reference diatom community. The model predictions (EQRs) responded significantly to eutrophication and intensive agriculture pressures, but were not related with sewages, hydromorphological alterations and extensive agriculture pressures. These results demonstrated the accuracy of the diatom model in predicting nutrient enrichment in Northern Spanish rivers and streams.

Biofilm is an important component of small streams, and it is highly sensitive to variations in water temperature. Therefore, it is expectable that the warming predicted for this century will be reflected in its communities. In this study, we investigated the effects of experimental warming on biofilm growth in a small forest stream in Central Portugal. The stream was longitudinally divided in two halves, both at ambient temperature during ambient period; the following months (warmed period), one stream half remained at ambient temperature (control half) and the other half was experimentally warmed by ~3 °C (experimental half), following a before-after control-impact design. Biofilm variables (biomass, chlorophyll-a and chlorophyll-c concentrations, autotrophic index, and diatom density) were determined from epilithic samples collected from both stream halves three times during the ambient period and five times during the warmed period. The experimental warming led to a significant increase in biomass, chlorophyll-a, chlorophyll-c concentration, and diatom density, especially in the winter months. Future warming, especially during the colder months, may thus stimulate biofilm growth, which may strengthen the autotrophic pathways of these systems traditionally based on detritus.

A new benthic freshwater diatom, Fragilaria rinoi Almeida & C.Delgado sp. nov., is described from river periphyton samples in Portugal. Fragilaria rinoi sp. nov. is illustrated and discussed based on populations collected from the Vouga, Mondego and Lis river basins in central Portugal and compared with the type material of Fragilaria vaucheriae (Kütz.) J.B.Petersen. The morphological features of the new diatom species are documented through light and scanning electron micrographs, including a comparative analysis with related species of the genus (F. candidagilae Almeida, C.Delgado, Novais & S.Blanco, F. intermedia Grunow in Van Heurck, F. neointermedia Tuji & D.M.Williams, F. recapitellata Lange-Bert. & Metzeltin, F. perminuta (Grunow) Lange-Bert., F. vaucheriae and F. microvaucheriae C.E.Wetzel & Ector). Fragilaria rinoi sp. nov. is characterized by solitary cells without spines, lanceolate valves with slightly rostrate apices, a narrow, linear axial area, and a large, unilateral central area. Fragilaria rinoi sp. nov. may be confused with F. microvaucheriae in terms of length, striae density and outline, although a morphometric analysis revealed that F. rinoi sp. nov. is significantly wider. Fragilaria rinoi sp. nov. is present in rivers with high dissolved oxygen concentrations, medium to high conductivity, neutral to slightly alkaline pH and high mean values of nitrates and ammonium.

Fragilaria candidagilae Almeida, C. Delgado, Novais & S. Blanco is a new araphid diatom species, described from samples collected in central and southern Portugal (SW Europe). Fragilaria candidagilae has linear-lanceolate valves with strongly capitate apices, without spines, and alternate punctate striae. This taxon presents siliceous plaques on the valve mantle edge, two apical pore fields in the poles and siliceous depositions on the outer areolar openings in the form of rounded floating disks. The morphology of the new diatom species is documented by light and scanning electron micrographs and discussed in detail, including a morphological comparison with the type material of similar taxa such as Fragilaria recapitellata, F. capucina, F. intermedia, F. neointermedia and F. perminuta to confirm it as a new species. Statistical comparison of morphometric characters and valve shape analysis were based on at least 20 valves. Ecological notes were also included. Considering morphology and morphometry, together F. candidagilae is clearly different from other species.

This work presents a combination of geochemical, mineralogical, and biological data obtained in water reservoirs located in one of the most paradigmatic mining regions, suffering from acid mine drainage (AMD) problems: the Iberian Pyrite Belt (IPB). Four water reservoirs located in the Spanish sector of the IBP, storing water for different purposes, were selected to achieve an environmental classification based on the effects of AMD: two mining dams (Gossan and Águas Ácidas), a reservoir for industrial use (Sancho), and one with water used for human supply (Andévalo). The results indicated that the four reservoirs are subject to the effect of metallic loads from polluted rivers, although with different levels: Águas Ácidas > Gossan > Sancho ≥ Andévalo. In accordance, epipsammic diatom communities have differences in the respective composition and dominant taxa. The dominant diatoms in each reservoir indicated acid water: Pinnularia acidophila and Pinnularia aljustrelica were found in the most acidic dams (Gossan and Águas Ácidas, with pH <3), Pinnularia subcapitata in Sancho (pH 2.48-5.82), and Eunotia exigua in Andévalo (pH 2.34-6.15).

The objective of this study was to evaluate whether biological methods based on epilithic littoral diatoms are a valuable complement to other biological elements for the assessment of the ecological potential of reservoirs in Portugal, in accordance with the requirements of the European Water Framework Directive. The statistical analysis performed (PCA, DCA, ANOSIM and SIMPER) based on the study of diatom communities of 18 reservoirs allowed the following results: (i) the separation of all the a priori defined types (North, Main Courses and South) was proved; (ii) there were no significant differences between reservoirs classified as reference and non-reference and (iii) the classification of the reservoirs as reference or non-reference based on the use of the diatom Specific Pollution sensitivity Index as a complementary variable allowed the definition of Maximum Ecological Potential reservoirs for the North and South types. Methods based on the use of epilithic littoral diatoms can therefore contribute, together with other biological elements, for the assessment of the ecological potential of aquatic lentic systems in Portugal, almost exclusively constituted by reservoirs.
