Frequently exposed to natural agents such as waves, wind, tides, storm activity, seasonal changes and anthropogenic agents, coastal areas are tangibly high energy environments and therefore subject to considerable dynamics. In order to mitigate and reduce the impacts on these areas, different types of coastal protection systems can be implemented. Rockwalls and breakwaters are the most ordinary structures

HIDRALERTA is a forecast and early warning system for coastal and port regions capable of predicting emergency situations, as well as carrying out risk assessment. The system concentrates on evaluating wave overtopping and flooding scenarios. It uses offshore sea-wave and wind forecast data, as well as tide data, as input to determine wave overtopping at specific locations. The calculation of the mean

Coastal and port structures represent a large economic investment for society during their lifetime. Therefore, there is a need for proper coastal planning and management. In order to do that, wave and current loads must be considered by determining their level where the coastal structure should resist, otherwise they may suffer extensive damage due to these environmental loads. In this study, a new

Dune restoration projects that integrate vegetation efforts with natural, sustainable, and soft solutions have become increasingly popular in coastal communities. Eco-restored dunes have high aesthetic value and are likely to be more resilient to near-surface wind effects and/or minor storms events. However, environmental-friendly restoration strategies still lack scientific insight from systematic

Transitional waters are ecosystems of important naturalistic value and enjoy different forms of protection. They are often subject to the threat of pollution phenomena due to anthropic activities and therefore objects of research for the choice of good monitoring, control and management practices. This study deals with the environmental analysis, conducted with water quality measurement campaigns and

This study presents the benefits of the application of multivariate techniques for the hazard assessment of a heavily polluted marine ecosystem. The study area, named Mar Piccolo, near Taranto city (Southern Italy), is a shallow marine basin located nearby an industrial compromised area, declared by the national government as Contaminated Site of Environmental Interest (SIN) due to the presence of

Between the evening of October 23rd and the evening of October 24th 2017, a sea storm hit the city of Bari, along the Adriatic coast, in the south of Italy, causing widespread damages. Due to the absence of direct observations of wave characteristics, the present paper is aimed to (i) compare the development of the occurred sea storm as hindcasted by ’84 method with the predictions by atmosphere-ocean

Abstract This paper aims to evaluate spatiotemporal variability of the mean sea level pressure trends over the Black Sea using the gridded 40-year (1979-2018) reanalysis mean sea level pressure data from two different datasets. These datasets are the European Centre for Medium-Range Weather Forecasts ERA-Interim with a spatial resolution of 0.25° and temporal resolution of six hours, and the National

Sediment deposition is an issue affecting many rivers. To oppose it, sediment withdrawals are often used. However, this practice can trigger further problems in river and coastal sections but, on the other hand, periodic removal of deposited sediments can reduce flooding risk. Also, these sediments can be used for beach nourishment. Therefore, before carrying out a sediment withdrawal, it is necessary

Steel slags are side products of iron and steel industry and are suitable for a variety of applications. In the present paper, the assessment of the hazard associated with steel slags used as harbor piers backfilling material was performed. The analyses were conducted on 64 samples (soil and groundwater) collected in 17 sites located in one of the piers of Taranto city (South Italy), a highly industrialized

Maritime works often require sediment handling activities such as dredging and disposal, to maintain harbors and channels, nourish sandy beaches as well as to carefully remove and relocate contaminated materials from the bottom of estuarine and coastal areas. Such operations often lead to an increase in the concentration of suspended sediments in water columns, which in turn causes adverse effects

Coastal soil erosion can be recognized as the most alarming environmental issue since, causing shoreline retreat, reduces the area available for plant habitat survival, highly influencing their health status, and, consequently, limiting their ability in beach front properties protection. A deep knowledge of vegetation changes is required to identify the proper strategy to be adopted to face soil erosion

Seasonal dynamics of microzooplankton and changes in environmental condition were analysed during a one-year field sampling campaign in the Sea of Oman at two different stations. Monsoon winds in this region cause distinct seasonality patterns with high primary productivity during the south-west monsoon in summer (June to October) and north-east monsoon periods in winter (November to March). Microzooplankton

The foodweb of El Tóbari Lagoon (central-east Gulf of California) was studied for four seasons through the carbon and nitrogen isotopic characterization of primary producers, invertebrates, fish, birds and potential food sources. The range of δ13C measured was much wider for potential food sources than for consumers. Many organisms presented enrichments of δ13C and δ15N values. There was a clear trend

The history of the Atlantic Salmon (Salmo salar), also referred to as Salmon below, in Lake Ontario is an accumulation of authentic published accounts, which were almost completed by J. R. Dymond before his death. H. H. MacKay completed the work on Dymond’s behalf (Dymond and MacKay, unpublished, 1966), but it remained largely unknown. The present authors (MEB, EH, PWB) have sought to present an updated

Fisheries productivity in the Laurentian Great Lakes has changed dramatically over the past century. Invasions of non-native species and anthropogenically induced environmental changes in habitat quality and quantity have significantly altered the species composition and abundance of Great Lakes fishes, thereby affecting the social and economic well-being of coastal communities that rely on the good

This overview compares algal blooms and pelagic fisheries of the Arabian Gulf with the Sea of Oman. The data consist of remotely sensed characteristics, directly sampled and modeled. Elucidated seasonal trends were based on 15-year seasonal means, as well as weekly time series of physical parameters. The environmental characteristics (namely photosynthetically available radiation, atmospheric pressure

Annual bottom trawl surveys were initiated in the 1970s in Laurentian Great Lakes Superior, Huron, Michigan and Ontario and in 1990 in Erie to provide annual assessments of the status and trends of prey fish communities. Native Cisco Coregonus artedi and Bloater C. hoyi dominated the prey fish community of Lake Superior. Prey fish communities in lakes Huron and Michigan were dominated by nonnative

Late in the 20th Century, participants in a trans-jurisdictional fisheries research network in the Great Laurentian Basin collaborated with participants of other research networks (waterfowl, piscivorous birds, benthic insects, plankton, bacteria, meteorology, hydrology, etc.) in a mega-scale happening during the years 1967 to 1992 that I call ‘The Great Laurentian Spring’. With a basin-wide version

Resacas of the lower Rio Grande River (secondary channels, distributaries, oxbow lakes) are vital freshwater wetlands under intense anthropogenic pressure. Many of these wetlands have their water levels tightly managed and some are being restored. Reliable bioassessment methods to effectively discriminate among resacas of differing ecological status are needed. Common components of bioassessments for

If it is true that each generation stands on the shoulders of the one preceding, then our generation is indebted to Henry Regier for significantly elevating today’s, and tomorrow’s, Great Lakes fisheries and aquatic ecosystem science and policy community. It seems self-evident now that limnology and fisheries management are inextricably connected. But not so long ago, practitioners of the two scientific

Canada and USA have over a 100-year history of international cooperation on Great Lakes management. For over 30 years, federal, state, and provincial governments have successfully used locally-defined ecosystem approaches to develop and implement remedial action plans to restore beneficial uses impairments in 43 Great Lakes Areas of Concern. Each remedial action plan identifies use impairments/causes

This special issue for the Journal, Aquatic Ecosystem Health and Management, is the result of a desire to recognize a truly unique person and distinguished fisheries and aquatic scientist, Dr. Henry Regier. The articles included in this special issue attempt to highlight Henry’s outstanding contributions to our understanding of Laurentian Great Lakes science and management, in addition to his compassionate

Different chemometric approaches were used to determine generic patterns in the temporal and spatial variations in the coastal water quality of the northern Yellow Sea off Yantai, China. Hierarchical cluster analysis grouped the 16 months into two periods (i.e. March-October and November-February), reflecting strong seasonality in the data, and grouped the 12 sampling sites into two clusters (i.e.

This study was conducted to assess the recruitment rate of coral spats and other invertebrates near to the coral reef ecosystem of Gulf of Mannar. The reef region examined was at Kurusadai Reef Complex (Gulf of Mannar) for this assessment. There were two sets of invertebrate settlement tripods deployed and exposed at a depth of 2m. Seventy two settlement tiles measuring 20x20 cm in two different angles

The focus of this study was the temporal and spatial variations of extreme significant wave heights and nearshore return-period wave heights in the South China Sea, based on the wave model and European Reanalysis-Interim data from 1979–2016. Measured buoy data were available from near Yongxing Island for comparison with the reanalysis data during the passage of typhoons. Annual maximum significant

Throughout his career, Dr. Henry Regier’s science and scholarship includes numerous contributions that cross disciplines and inform policy. This review of examples of his politically-relevant science publications spans six decades. Regier’s publications emphasize themes that cross the various boundaries of expert-layperson, state actors-society, public-private, and government-academic sectors. His

When dealing with invasive fishes, permanent barriers may inhibit spread, but may not be feasible due to costs and logistical constraints. Alternatively, non-permanent barriers using electricity, light, sound, pressure, bubbles, and CO2 are being developed and deployed in efforts to limit and prevent the spread of aquatic invasive species or to achieve fish guidance and conservation. However, the effectiveness

Phytoplankton is an important indicator of, and responder to, environmental changes. This study aims to reveal the response of a phytoplankton community to environmental changes, especially the lev...

Growth parameters, mortality, growth performance index and exploitation ratio of Oreochromis niloticus were assessed based on the length-frequency data collected fortnightly from the Allahabad stre...

It is more cost effective to prevent invasions than to eradicate or control invasive species once they are established. We therefore need a thorough knowledge of the pathways by which invasive spec...

Fisheries are coupled human and natural systems across space and time, involving movements of fish, money, and information in a globalized world. However, these social-ecological interactions over local to global scales are largely absent from the fisheries literature, as fisheries research to date has often been discipline- and location-specific. We analyzed this knowledge gap by using an emerging

Coastal wetlands in Qinhuangdao play a vital role in the regional ecological environment. The value of the ecosystem services of the coastal wetland was evaluated in terms of provision services, regulation services, culture services and supporting services by particular methods. Results indicated that coastal wetland area in Qinhuangdao was about 39,918.00 hm2 and annual value of ecosystem services

Based on the geometry and surface in Daya Bay, we artificially divided the reclamation projects into three periods to analyze the influences and changes on hydrodynamic conditions as a result of the reclamation projects. Three periods of tidal current fields, tidal prisms, and water exchange capacity are simulated by the Finite-Volume, primitive equation Community Ocean Model and the characteristics

Boubyan Island is essentially undeveloped and the largest island in the northwest of the Arabian Gulf. Small otter trawls were used to sample 12 stations circling Boubyan Island each month, except November, from February 2004 through February 2005. All trawl catches, with the exception of large Skates and Rays, were returned to the laboratory for identification and processing. The total number of individuals

Leizhou Peninsula is located in the Indo-Burma biodiversity hotspot. However, information about freshwater fish species in this peninsula is very scarce. Based on surveys and a literature review, a total of 100 freshwater fish species (92 native and eight non-native) within seven orders, 21 families and 70 genera, have been recorded in the Leizhou Peninsula. Four species, Mud Carp (Cirrhinus molitorella)

Analysis of beach profile data over the period 1992–2014 at 14 beaches on mainland Anguilla and the offshore cays of Prickly Pear and Sandy Island, showed an overall erosion trend with a mean erosion rate of −0.51 m yr−1. Eleven beaches showed erosion, while three beaches showed slight accretion. Over the period of measurement nine hurricanes passed close enough to Anguilla to significantly impact

Environmental DNA is one of the most promising new tools in the aquatic biodiversity monitoring toolkit, with particular appeal for applications requiring assessment of target taxa at very low population densities. And yet there persists considerable anxiety within the management community regarding the appropriateness of environmental DNA monitoring for certain tasks and the degree to which environmental

The news of the sudden passing of Dr. Denis Lynn came as a great shock to members of his former Department at the University of Guelph. Denis had spent the bulk of his career here, having completed his undergraduate degree in marine biology at the University of Guelph and returning as a faculty member in 1977, after earning a PhD at the University of Toronto and completing a stint as a postdoctoral

While contemplating what to write about my late colleague Denis, whose many outstanding contributions have left an everlasting fingerprint on our knowledge of Great Lakes ciliates, foodwebs and general ecology, I had a sudden leap down memory lane. It all started when our phycologist observed a considerable number of ciliates while analyzing Lake Ontario phytoplankton samples in the early 1990s. Initially

Denis,It’s ironic that when facing a problem like this – being asked to write a piece about the way you affected us in the labs we share – our first instinct would be to come and talk to you, to ge...

According to my files from many years ago, my first contact with Denis Lynn dates back to February 1974, when he sent me a letter with questions related to extrusomes in ciliates, the topic of my doctoral thesis. Denis was in the completion phase of his PhD thesis (Figure 1) and I had just started my first position as Assistant Professor at the University of Heidelberg. Later, Denis and I met from

I first met Denis Lynn over 45 years ago at a meeting of the Society of Protozoologists (now known as the International Society of Protistologists ISOP), when he was a graduate student working with John Corliss and Eugene Small at the University of Maryland. My interest in the ecology of marine ciliates had connected me to an array of faculty and graduate students in the Society who were focusing on

Writing this piece, I was faced with a question: how to put on paper and adequately express the type of mentor Denis was. Good mentorship is something that everyone hears about but only disproporti...

Although Dr. Denis H. Lynn was not my manager, he was an old friend of my supervisor, Professor Weibo Song and his group. I got to know Dr. Lynn when I first started ciliate taxonomy research, as a...

The ciliate community of the Bay of Quinte, Lake Ontario was assessed over a six year period from 2003 – 2008. One eutrophic site in the upper bay (Belleville) and one more oligotrophic site in the lower bay (Conway), were included in the survey. Both sites contained a mixture of Haptoria, Strobilidium, Halteria, Strombidium, and Vorticella, although the relative proportions varied among sites resulting

Aloricate ciliates are essential members of the pelagic microbial foodweb and are easy to identify in samples, yet the taxonomic database is insufficient and many species have yet to be described. Individuals from the Phylum Ciliophora Doflein, 1901, Order Choreotrichida Small and Lynn, 1985 were collected from the epilimnion (upper 20m) of Lake Ontario in the spring, summer and autumn of 1990 and

Ciliated protozoa are important components of the plankton of aquatic systems with ability to recycle nutrients and to link microbial food webs to metazoans. This is because they are numerous and have higher growth rates compared to other unicellular eukaryotes of similar size. Predation and competition are some of the factors that negatively affect their abundance and growth. Studies documenting the

In this study, biocontrol of harmful effect of cyanobacterial blooms and their toxins by “flocculation-biosorption” was achieved. Five fungal species were isolated from decayed cyanobacterial bloom which are: Aspergillus fumigatus, A. niger, Penicillium, Trichoderma ressei and Mucor rouxii. We chose the last species’ pellets because they are the most stable and cocultured with Anabeana sp. (1:5 fungal:

The present study envisages the importance of monitoring and management of freshwater springs of Kashmir Himalaya due to role they play in meeting ever-increasing drinking water demands and maintaining various ecosystem services. Therefore, some of the most pressing issues fundamental to the existence of springs is their monitoring and management because of their geological, ecological, scientific

A periphyton-based index for biological integrity was developed to assess the ecological status of lakes and reservoirs in Baiyangdian Watershed, China. Periphyton and environmental surveys were conducted at 20 sites during 2009-2010.
