Abstract:

Gli ecosistemi marini sono sottoposti a diversi fattori di stress di origine antropica, i cui effetti non sono ancora del tutto noti. Questo gap conoscitivo rappresenta un punto cruciale, in quanto, la conoscenza degli effetti delle attività umane è essenziale per l’applicazione di piani di monitoraggio e di adeguate strategie di mitigazione. Di conseguenza, in questa tesi, sono stati selezionati e studiati quattro diversi tipi di pressioni antropiche; allo scopo di aumentare le conoscenze disponibili come richiesto dalla MSFD.

Abstract:

Southeast Florida’s continual urban expansion will potentially increase anthropogenic pollution in adjacent coastal marine systems. Furthermore, increased nutrient loads could have detrimental effects on the already threatened Florida Reef Tract. The present study uses a stable isotopic approach to determine the sources and the impact of nutrients on the Florida Reef Tract. δ13C and δ15N analysis of macroalgae, sponges, and sediment were analyzed in order to determine nutrient inputs in this region. While δ13C data did not display any significant trends spatially, δ15N values of the majority o

Abstract:

Marine environments play a central role for the planet, yet an understanding of how climate change is affecting marine ecosystems has been poorly developed. There is now growing evidence that human activities are driving rapid changes from local to global scale. In last decades, the rates of change is accelerating and may exceed the potential tolerance of many organisms to adapt. Ecological systems and marine organisms have evolved under different regimes of stress and disturbances both of natural and anthropic origin and intrinsically connected. No ecosystem is unaffected and marine coastal h

Abstract:

Coastal marine ecosystems are among the most impacted globally, attributable to individual and cumulative effects of human disturbance. Anthropogenic nutrient loading is one stressor that commonly affects nearshore ecosystems, including seagrass beds, and has positive and negative effects on the structure and function of coastal systems. An additional, previously unexplored mechanistic pathway through which nutrients may indirectly influence nearshore systems is by driving blooms of benthic jellyfish.

Abstract:

Coastal ecosystems, including estuaries, provide a range of services to humans, mediated by the species within these ecosystems. Microphytobenthos (MPB) play a vital role in many key processes within estuarine ecosystems, and provide a food source for higher trophic levels. Anthropogenic activity is already causing changes to ecosystems, through pollution, overexploitation and, more recently, climate change. Increasing temperature and carbon dioxide levels, and altered biodiversity, are likely to affect species, and their interactions, within these ecosystems. Much ecological research has focu

As we have become more aware of the value of vegetation in the stabilization of coastal sand dunes, there has been an increasing desire to protect valuable native species in coastal habitats.

The Australian pine (Casuarina eguisetifolia) introduced to south Florida in 1898 by Fairchild, has become a weed species on beaches, supressing the native grasses associated with dune formation by its exudation of allelopathic substances.

Seabirds are an important link between their marine feeding areas and their terrestrial breeding environments, transporting both marine-derived nutrients and contaminants to land via their excreta, feathers and carcasses.

While providing the nutrient subsidies that shape the terrestrial ecosystem of many Arctic sites, seabirds may focus contaminants into their nesting sites at potentially toxic levels. Here, w

Abstract:

Cuba’s expansive coral reefs and mangrove habitats provide a variety of ecosystem services to coastal communities including nursery grounds for fisheries, shoreline stability, and storm and flood protection. While Cuba’s coastal habitats are some of the most preserved in the Caribbean, they are under increasing threat of degradation from the impacts of climate change, increased tourism, and coastal development. With the goal of sustainable development, Cubans need to assess the storm and flood protection benefits these coastal habitats provide, and integrate this information into future expans

Abstract:

Measurements of carbon (13C/12C; δ13C) and nitrogen (15N/14N; δ15N) stable isotope ratios have become important tools for: estimating energy flow and trophic positions in aquatic foodwebs; comparing food webs; and aiding in the tracking of wide-ranging consumers. However, each of these applications requires accurate measurements of isotopic signatures in organisms at or near the base of the food web (e.g. autotrophs and their consumers), which act as basal reference points from which to calibrate inferences. Therefore, understanding variations in isotopic baselines, and the mechanisms leading

Abstract:

The South African coastal and marine environment is an essential ecologic and economic asset. Its associated services and products are substantially contributing to economic growth and sustainable development of the country. However, it is internationally and nationally recognised that land-based marine pollution (LBMP) is the most important single risk to the health and sustainability of coastal and marine waters and the associated ecosystems. The regulation of LBMP at the national level is still difficult and challenging. The issue of LBMP management has only recently been introduced in Sout

Abstract:

Les écosystèmes marins côtiers sont constament soumis à des pollutions, notamment aux hydrocarbures, du fait de leur localisation et de leurs caractéristiques environnementales. Le rôle clé des microorganismes dans la dégradation de ces polluants est aujourd’hui très bien décrit. Toutefois, les conditions d’oxygénation fluctuantes dans ces environnements côtiers, dues aux marées et aux activités de bioturbation de la macrofaune, influencent les communautés microbiennes.Ainsi, ce travail de thèse a eu pour objectif de caractériser, l’assemblage de communautés microbiennes hydrocarbonoclastes de
