Seascape connectivity of European anchovy in the Central Mediterranean Sea revealed by weighted Lagrangian backtracking and bio-energetic modelling
2020
AbstractEcological connectivity is one of the most important processes that shape marine populations and ecosystems, determining their distribution, persistence, and productivity. Here we use the synergy of Lagrangian back-trajectories, otolith-derived ages of larvae, and satellite-based chlorophyll-a to identify spawning areas of European anchovy from ichthyoplanktonic data, collected in the Strait of Sicily (Central Mediterranean Sea), i.e., the crucial channel in between the European and African continents. We obtain new evidence of ecosystem connectivity between North Africa and recruitment regions off the southern European coasts. We assess this result by using bio-energetic modeling, …
Practical Movements: Kinetic rituals in the Ancient Western Mediterranean
2011
Scholars have studied the long-distance movements of people and goods in Phoenician and Punic society between the eighth and the second centuries BC in considerable depth. However, little attention has been paid to travelling, walking and sailing as common activities in their daily lives. it was through living in and moving through landscapes and seascapes that people constructed their sense of place. Sacred places may have been nodal points in these settings and everyday movements may well have become ritualized. This article develops the idea that journeys to shrines might be considered as pilgrimages and stresses the kinetic aspect of these practices. I suggest that trips to shrines were…
Derek Mahon's Literal Littorals
2012
International audience; A transversal reading of Derek Mahon's poems reveals his predilection for coastal landscapes: vistas of sea and seashore, harbour towns or seaside resorts. Suffused as they are with elemental symbolism (waves, wind, rain and storm, rocks, cliffs and misty piers), those liminal spaces take on a metaphysical dimension. The landscapes that the poet invests are the objective correlatives of his sense of alienation and vulnerability; they are mindscapes (paesagio mentale or reflections of the inner self) as much as territories to be paced and explored. This paper thus examines how the natural and the urban, the visual and the acoustic, the a-temporal and the modern or pos…
Local recruitment of Atlantic cod and putative source spawning areas in a coastal seascape
2021
Abstract Increased knowledge on connectivity is crucial to our understanding of the population dynamics, genetic structure, and biogeography of many coastal species. In coastal marine populations, the main factor for structuring is thought to be the degree of isolation and confinement, limiting genetic exchange between populations. However, many offshore populations use the coastal areas as nursery grounds, but venture back to natal spawning grounds as adults. Therefore, increased knowledge on the connectivity between coastal and offshore populations is crucial to ensure correct assessment of coastal living resources. Here, we combine genetic assignment data of Atlantic cod recruits sampled…
Ann Radcliffe’s Gothic Romances and the Sea
2021
Biographical materials and the writer’s journals show that Ann Radcliffe had some personal knowledge of the sea and to some extent of sailing. She was also a lover of nature, an enthusiast of 17th -century landscapists, a connoisseur of Pre-Romantic poetry, who was also familiar with contemporary esthetic tastes and theories. In this context, the article analyzes seascapes, maritime and nautical references, motifs of storm and shipwreck in Radcliffe’s Gothic romances, including some poetical lines inspired by the sea with which The Mysteries of Udolpho is interspersed. The writer’s descriptions of the sea and her use of this element in her works are discussed in relation to her fictional ch…
Evaluating the ecological effects of Mediterranean marine protected areas: habitat, scale and the natural variability of ecosystems
2000
The capability to detect and predict the responses of marine populations and communities to the establishment of marine protected areas (MPAs) depends on the ability to distinguish between the influences of management and natural variability due to the effects of factors other than protection. Thus, it is important to understand and quantify the magnitude and range of this natural variability at each scale of observation. Here we review the scale of responses of target populations and communities to protection within Mediterranean MPAs, against their ‘normal’ spatio-temporal heterogeneity, and compare those with documented cases from other temperate and tropical marine ecosystems. Additiona…
Claiming the sea: Bronze Age fortified sites of the north-eastern Adriatic Sea (Cres and Lošinj islands, Croatia)
2017
ABSTRACTMore than 1,000 Bronze and Iron Age hillforts can be listed for the eastern Adriatic region. These constructions left a mark on the landscape which is still perceptible today. In some cases, such as the island of Losinj, this density is challenging to explain: almost thirty hillfort (or simply hilltop) sites were recorded on a rugged island with an area of 74km2. Different factors potentially involved in the formation of this settlement pattern are discussed (territorial control, surveillance, control of maritime networks), only to show that without considering some kind of symbolic display a plausible explanatory model cannot be devised. A new reading of the coastal seascape is pro…
Habitat effects on population connectivity in a coastal seascape
2014
Published version of an article from: Marine Ecology Progress Series. Also available from Inter Research: http://dx.doi.org/10.3354/meps10944 Knowing how population connectivity varies across heterogeneous habitats can provide insight into the mechanisms underlying population structuring, and ultimately help to inform conservation and management actions. We studied whether the spatial extent of connectivity in coastal Atlantic cod Gadus morhua varied with coastal topography, hypothesizing that connectivity during all life stages would be greater among open, exposed habitats compared to sheltered, fjord-like habitats. We tested this hypothesis using (1) an extensive mark-recapture data set t…
3D-Reconstruction of a Giant Posidonia oceanica Beach Wrack (Banquette): Sizing Biomass, Carbon and Nutrient Stocks by Combining Field Data With High…
2022
Beach wracks are temporary accumulations of vegetal detritus that can be found along coastlines all over the world. Although beach wracks are often perceived as a nuisance for beach users, they play a crucial ecological role in carbon and nutrient connectivity across ecosystem boundaries, especially when they reach a relevant size, as in the case of the wedge-shaped seagrass accumulations called banquette. In this study, three-dimensional mapping of a giant Posidonia oceanica banquette was carried out for the first time using high-resolution UAV photogrammetry combined with field sampling and compositional and chemical analysis. The combined approach allowed a reliable estimation of the amo…
