title: The coastal habitat injury assessment in Prince William Sound, Cook Inlet-Kenai Peninsula and Kodiak-Alaska Peninsula, Alaska: 1989 - 1991

description: Study History: Comprehensive assessment of coastal habitat was initiated as Coastal Habitat Study No. 1 in 1989. Phase I was conducted in summer 1989/spring 1990 and involved site selection/ground truthing. Phase II involved intensive evaluation of study sites to determine extent of injury to natural resources in supratidal, intertidal and subtidal areas. Phase II commenced in the fall of 1989 and continued through the summer of 1991. The supratidal component was completed in 1991 and a final report was submitted separately. The subtidal portion was integrated into a suite of other subtidal studies and findings were also reported separately. Draft preliminary status reports were issued for the intertidal componenet in 1990, 1991, 1992 and 1993 by Highsmith et al. as Coastal Habitat Study No. 1: Phase II in 1990 and 1991 and No. 1A in 1992 and 1993.

Abstract: The Coastal Habitat Injury Assessment Study was initiated to assess injury to intertidal habitats impacted by the Exxon Valdez oil spill. The study, conducted from 1989-1991, encompassed three major geographical areas impacted by the spill: Prince William Sound, Cook Inlet-Kenia Peninsula and Kodiak-Alaska Peninsula. Oiled sites were selected randomly and matched with non-oiled sites and classified into sheltered rocky, exposed rocky, coarse textured or estuarine habitat. Statistically significant differences between oiled and non-oiled sites were interpreted as impact due to the spill and/or clean-up activities. Most observed differences varied across regions, habitats and tidal heights. Algae, especially the perennial Fucus, was generally negatively impacted on oiled sites. Conversely, an increase in annual and ephemeral species in the lower intertidal occurred. Limpets, mussels, littorines, and the high cockscomb prickleback were injured by the spill, while oligochaetes and a single barnacle species were enhanced at most tidal heights following the spill. Although intertidal communities showed widespread impact from oiling/clean-up activities for algal, invertebrate and fish components, data revealed most habitats were recovering but had fully recovered by 1991.

title: Cell biovolume and surface area in phytoplankton of Mediterranean transitional water ecosystems: methodological aspects

description: 1 - A series of experimental researches highlighted the role of morphometric parameters of phytoplankton guilds as descriptors of the ecological status of transitional water ecosystems (TWs).
2 - However, at present, standardized or common methodologies for their use do not exist. In this work, we develop a procedure for the determination of biovolume and surface area in phytoplankton guilds of Mediterranean TWs.
3 - Phytoplankton biovolume and surface area are included among the most studied morphometric descriptors. They can be estimated by associating the algae with similar geometric forms and determining the volume of these by measuring the linear dimensions required for its calculation under the light microscope.
4 - Here, a set of geometric models is suggested for calculating the cell biovolumes and surface area of 235 phytoplankton genera, deriving from the analysis of 869 phytoplankton species, found in transitional water ecosystems of the Mediterranean Ecoregion. The equations were designed to minimize the effort of microscopic measurements.
5 - The similarities and differences between the geometric models here proposed and previously published are discussed.

title: Taxonomic composition of the phytoplankton community of Lesina lagoon (Apulia-Italy)

description: 1 - Transitional waters are characterized by specific ecological features and an intrinsic heterogeneity; because of their high vulnerability they need particular conservation and management measures, specifically based on the knowledge of their biological and taxonomic diversity.
2 - In particular, the study of phytoplankton communities is widely used as an important water quality indicator because of its high species richness and sensitivity to environmental factors.
3 - This study investigated the phytoplankton community of the Lesina lagoon, describing its taxonomic composition and abundance in order to provide a systematic list that could be useful to improve our knowledge of the Lesina lagoon biological features and, in general, of transitional water phytoplankton communities.
4 - In the whole sampling area we identified 62 taxa, belonging to 18 classes or groups; Dinophyceae were the taxonomic group with the highest percentage of overall phytoplankton cell density (16.2 %), following by Cryptophyceae (11.0%) and Bacillariophyceae (10.1%). No dominant taxa were found considering all studied area.
5 - Phytoplankton taxonomic structure in the Lesina lagoon was characterized by Dinophyeceae and Bacillariophycea and also by a large number of species of small dimensions (particularly Phytoflagellates and Cryptophyceae), that are typical of the environments, like transitional waters, characterized by high instability in the structural characteristics of the water mass and in resource availability.

title: A checklist of phytoplankton species in the Faafu atoll (Republic of Maldives)

description: 1 - Phytoplankton is considered as a natural bioindicator of water quality because of its sensitivity and its complex and rapid response to change of environmental conditions.
2 - The aim of this study was to investigate and provide important new information about the checklist of phytoplankton species in different lagoons of the Faafu atoll in Maldivian archipelago.
3 - A total of 140 phytoplankton taxa were identified. In terms of species richness, dinoflagellates were the largest group with 55 identified taxa belonging to 22 genera. Coscinodiscophyceae recorded 38 taxa belonging to 14 genera; Bacillariophyceae represented by 18 taxa belonging to 10 genera and Fragilariophyceae recorded 11 taxa belonging to 8 genera. Most of the other classes were poorly represented with only one or , at most, two taxa for each genus.

title: Phytoplankton composition in the coastal Magnetic Island lagoon, Western Pacific Ocean (Australia)

description: 1 - Coastal lagoons have traditionally been considered as transitional systems between continental and marine domains. The phytoplankton plays a key role in these aquatic environments, forming the base of the food web and having a substantial function in nutrient dynamics and in the carbon biogeochemical cycle.
2 - Due to their short life cycle, planktonic algae respond quickly to environmental changes and they are thus a valuable indicator of water quality. It is essential to investigate the development of phytoplankton populations to understand the biological functioning and to detect changes in aquatic systems.
3 - Phytoplankton studies in the Australian estuaries and lagoons are relatively scarce. This study has provided a broad perspective and preliminary information on taxonomic structure of phytoplankton guilds for the Magnetic Island Lagoon (Queensland, Australia). This work may provide valuable information of interest to later ecological studies.
4 - In the whole sampling a total of 143 taxa were identified. In terms of species richness, diatoms (Bacillariophyceae, Coscinodiscophyceae, Fragilariophyceae) and dinoflagellates (Dinophyceae) were the most important groups. In taxonomic terms, diatoms were the major contributor to the phytoplankton composition (~ 70%) whereas Dinophyceae were moderately abundant (~23%). Diatoms are a very important component in estuarine and shallow coastal wetlands and they are increasingly being utilized as indicators of environmental change.

title: Multi-scale biodiverity patterns in phytoplankton from coastal lagoons: the Eastern Mediterranean

description: 1 - The phytoplankton from Eastern Mediterranean coastal lagoons is analysed using a multi-scale approach, with the aim of testing if phytoplankton variations follow a hierarchical scheme based on eco-geographical location. The scale similarity is examined by using a taxonomic metric based on the Kullback-Leibler divergence and a related similarity index.
2 - A hierarchical sampling design was used to investigate variations in taxonomic composition and richness of phytoplankton assemblages. Data analyzed collected during summer season in 3 coastal lagoons in the Mediterranean Eco-region: two are located in Turkey (Akg�l and Paradeniz) and one is located in Greece (Korission). According to the Mediterranean typology, all lagoons are large, non-tidal and have mean salinity regimes of oligohaline (Akg�l), polyhaline (Paradeniz) and euhaline (Korission) designations.
3 - The taxonomic composition of phytoplankton assemblages varied markedly among lagoons, with the most representative phytoplankton in terms of taxa richness belonged to Chlorophyceae (33.33%) in Akg�l, to Dinophyceae (50.00%) in Paradeniz and to Dinophyceae (30.77%) in Korission.
4 - Within-habitat similarity was very high in all habitats and lagoons. At an ecosystem scale, phytoplankton was highly homogeneous in Akg�l and Paradeniz, suggesting that the distinctive physiognomic traits of the habitats exert a limited effect. In contrast, the phytoplankton is significantly heterogeneous in Korission, mostly because of the effect of the heterogeneous habitats, in fact the three sampled habitats showed well-differentiated characteristics.
5 - At an eco-regional scale, the pattern of similarity among lagoons suggests that local conditions (particularly salinity) and geographical location play roles of a comparable importance in determining the dissimilarity among phytoplankton guilds.
6 - The similarity index between adjacent lagoons having different salinity (Akg�l and Paradeniz) was comparable to the one between lagoons with similar salinity but different geographical location. This suggests that local conditions and geographical factors act in a complex way.

title: Occurrence of POPs in sediments and tissues of European eels (Anguilla anguilla L.) from two Italian lagoons: Varano and Orbetello

description: 1 - Total levels of persistent organic pollutants (polychlorinated biphenyls, organochlorine pesticides, and polycyclic aromatic hydrocarbons) in sediments and edible tissues (muscle and liver) from a fish species of great local commercial interest (Anguilla anguilla L., yellow phase) were determined in Varano and Orbetello lagoons, Italy. 
2 - The aim of this study was to improve knowledge on relationships occurring among levels of chemicals in sediments and fish tissues relating them reciprocally and to different intensities of human pressure. 
3 - Studied ecosystems were selected due to the notable scientific knowledge acquired by previous detailed research on meteorology, geomorphology, hydrodynamics, types and distribution of local factors linked to different sources of human-made pollution. Samplings were performed in July 2009 according to a logic model based on a priori defined factors of interest and obtained results were statistically analysed in order to evaluate the significance of observed data segregation related to the selected factors. 
4 - Concerning levels measured in sediments, significant differences were observed between lagoons in terms of .PAHs and .OCPs. According to National and international recognised sediment quality guidelines, results evidenced the occurrence of non-critical POPs values in sediments. 
5 - Results on sediments are associated to very high levels in eel's tissues. Concerning eels, Orbetello lagoon is characterized by significant higher values of .OCPs than Varano, evidencing the presence of an important OCPs local source. 
6 - Different human pressure levels produce significant differences in both sediments and eel's tissues in Varano and Orbetello lagoons.

title: Dynkin diagrams, support spaces and
representation type

description: This survey article is an expanded version of a series of lectures given at the conference on Advances in Group Theory and its Applications which was held in Porto Cesareo in June of 2011. We are concerned with representations of finite group schemes, a class of objects that generalizes the more familiar finite groups. In the last 30 years, this discipline has enjoyed considerable attention. One reason is the application of geometric techniques that originate in Quillen�s fundamental work concerning the spectrum of the cohomology ring v[25, 26]. The subsequent developments pertaining to cohomological support varieties and representation-theoretic support spaces have resulted in many interesting applications. Here we will focus on those aspects of the theory that are motivated by the problem of classifying indecomposable modules. Since the determination of the simple modules is often already difficult enough, one can in general not hope to solve this problem in a naive sense. However, the classification problem has resulted in an important subdivision of the category of algebras, which will be our general theme. The algebras we shall be interested in are the so-called cocommutative Hopf algebras, which are natural generalizations of group algebras of finite groups. The module categories of these algebras are richer than those of arbitrary algebras: 
� They afford tensor products which occasionally allow the transfer of information between various blocks of the algebra.
� Their cohomology rings are finitely generated, making geometric methods amenable to application. The purpose of these notes is to illustrate how a combination of these features with methods from the abstract representation theory of algebras and quivers provides insight into classical questions.

title: Graphs and Classes of Finite Groups

description: There are different ways to associate to a finite group a certain graph. An interesting question is to analyse the relations between the structure of the group, given in group-theoretical terms, and the structure of the graph, given in the language of graph theory. This survey paper presents some contributions to this research line.

title: A Checklist of phytoplankton species around the Equator in Guara�ras, Galinhos and Diogo Lopes lagoons (Rio Grande do Norte, Brazil)

description: 1 - Coastal lagoons show great fragility and vulnerability to the anthropogenic pressure. The understanding of physical, chemical, geological characteristics and ecological dynamics of lagoons is fundamental for planning the implementation of coastal management strategies in these ecosystems. The intrinsically high variability of phytoplankton communities in transitional environments should be taken into account not only because of phytoplankton ecological importance, but also because of the implications for environmental management.
2 - The aim of this study is a general description of the phytoplankton community in three coastal lagoons situated in the Rio Grande do Norte region, at the Northeast of Brazil.
3 - For the three lagoons, a total of 124 phytoplankton taxa were identified. In terms of species richness, diatoms were the largest group with 92 identified taxa belonging to 46 genera. At the class level, Bacillariophyceae recorded 39 taxa belonging to 18 genera; Coscinodiscophyceae recorded 39 taxa belonging to 21 genera and Fragilariophyceae recorded 14 taxa belonging to 7 genera. The group of the dinoflagellates recorded 15 taxa belonging to 6 genera and the Cyanophyceae was represented by 8 taxa belonging to 5 genera, including Trichodesmium erythraeum, a taxon related to toxic blooms.

title: Multi-scale spatio-temporal patchiness of macrozoobenthos in the Sacca di Goro lagoon (Po River Delta, Italy)

description: 1 - In this study, the macrobenthos from different habitats in the Sacca di Goro lagoon (Po River Delta, Italy) is analysed by following a multi-scale spatio-temporal approach, with the aim of evaluating the spatial patchiness and stability of macroinvertebrate assemblages in the lagoon. The scale similarity is examined by using a taxonomic metrics based on the Kullback-Leibler divergence and a related index of similarity.
2 - Data were collected monthly during one year in four dominant habitat types, which were classified on the basis of main physiognomic traits (type of vegetation and anthropogenic impact). Three of the selected habitats were natural (macroalgal beds, bare sediment and Phragmitetum) and one anthropogenically modified (the licensed area for Manila clam farming). Each habitat was sampled in a variable number of stations representative of specific microhabitats, with three replicates each.
3 - Of the 47 taxa identified, only few species were found exclusively in one habitat type, with low densities. No taxon was dominant in all the considered habitats.
4 - The results show that, in spite of the large overlapping of species, the spatio-temporal dissimilarity within each habitat type was higher than expected on the basis of the common physiognomic traits. This suggests that local factors (mainly hydrodynamism, quality and quantity of vegetal matter) play a significant role in determining the structure of the macroinvertebrate assemblages.
5 - The dissimilarity between habitats was significant and maintained all over the seasonal progression, indicating that the macroinvertebrate assemblages were steadily different. Each habitat allowed some specific taxa to maintain a significant population size, which is a prerequisite for preserving biodiversity.
6 - The variety of vegetation types and hydrodynamic conditions in the lagoon emerges as crucial for sustaining biodiversity and capacity to recover from disturbances.
