The mollusc Patella ferruginea, endemic to the Mediterranean, is the most endangered marine species of the list of the European Council Directive 92/43/EEC and it is presently under serious risk of extinction. Survival, growth rates and life‐history of this species were studied for the first time in this species. A total of 570 specimens (420 introduced in a new habitat and 150 as control) were marked and monitored over a three‐year period. Growth rates observed were mainly related to the… 
Growth and reproduction of the north-eastern Atlantic keystone species Patella aspera (Mollusca: Patellogastropoda)
This study revealed that currently the stock of P. aspera is under-exploited, nonetheless due to it’s slow growth and long life, continuous monitoring and the enforcement of the existing harvest regulations must be accomplished if future over- Exploitation is to be avoided.
Population Dynamics and Viability Analysis for the Critically Endangered Ferruginean Limpet
It is determined that the critically endangered limpet P. ferruginea is clearly overexploited in the study area, and may face local extinction within the next 20 y if harvesting activities are not controlled.
Life history traits of the exploited limpet Patella candei (Mollusca: Patellogastropoda) of the north-eastern Atlantic
Patella candei was found to be under-exploited in the investigated area; however, its slow growth and long life make it extremely vulnerable to over- Exploitation.
‘Impossible’ re-introduction of the endangered limpet Patella ferruginea Gmelin, 1791? Progress in resolving translocation mortality
This article describes the result of a field experiment where 97 P. ferruginea individuals were transported to a new site, using a technique which involved carefully moving the limpets whilst inactive (during low tide), still attached to their home scars on breakwater boulders, and the results were significantly positive.
Life-history trait of the Mediterranean keystone species Patella rustica: growth and microbial bioerosion
The present study is first to introduce the use of inner growth lines in Patella rustica shell sections as a reliable method for age determination and it provides the first insight into the growth patterns of this keystone species while taking the interference of microbial shell bioerosion in consideration.
Conservation status and updated census of Patella ferruginea (Gastropoda, Patellidae) in Ceuta: distribution patterns and new evidence of the effects of environmental parameters on population structure
The results indicate that substrate roughness and the area’s accessibility highly influence the abundance and population structure and those populations located on high topographic heterogeneity substrates show higher recruitment rates and lower percentages of larger individuals, while medium to low rugosity surfaces presented the opposite pattern.
It is indicated that sex change appears to occur at smaller sizes when large individuals (presumably females) are rare, and the fact that P. ferruginea may exhibit environmentally mediated sex change could influence population management decisions.
Is the establishment of MPAs enough to preserve endangered intertidal species? The case of Patella ferruginea in Mal di Ventre Island (W Sardinia, Italy)
The giant limpet Patella ferruginea is the most endangered endemic species in the Mediterranean Sea. It is at serious risk of extinction, especially along the coast of Corsica and Italy. The small
New records of the distribution and conservation status of the endangered limpet Patella ferruginea in Sardinia (Italy, W Mediterranean)
Patella ferruginea is an endemic and endangered limpet of the Mediterranean Sea. Its distributional range has been greatly reduced over the past century, mainly as a consequence of human pressure on


Distribution and population dynamics of the limpet Patella Vulgata L. in Bantry Bay
Aspects of reproduction and their implications for the conservation of the endangered limpet, Patella ferruginea
The results of the present study increase the maximum length for males by double that cited in previous literature and highlight the importance of strictly protecting females (i.e., most of the largest individuals, >60 mm), since their population percentage is very low, in order to develop adequate strategies to preserve the species.
Vertical and seasonal patterns in competition for microalgae between intertidal gastropods
Intentional grazing by the snail Nerita atramentosa and the limpet Cellana tramoserica caused similarly great reductions in abundance of microalgae — measured by direct counts and by estimation of chlorophyll analyses, demonstrating that intensity of competition will vary from place to place and time to time according to the densities and mixtures of the grazers, and according toThe availability of microalgal food.
Energetics of High and Low Populations of the Limpet, Acmaea Scabra (Gould)
The dynamics of naturally occurring high (zone 1) and low (zone 2) populations of the limpet, Acmaea scabra, were investigated on Bodega Head in Sonoma County, California to determine the seasonal pattern of reproduction and changes in size—specific weights.
