“…The most obvious change with latitude concerns the timing of spawning events, which tend to occur earlier in the northern part of the range. The main spawning period in P. vulgata starts in September in northern Scotland (Baxter, 1982(Baxter, , 1983Bowman & Lewis, 1986) and also in north-eastern England (Bowman, 1985;Bowman & Lewis, 1977, 1986, October-November in south-western Ireland (Thompson, 1980;McCarthy et al, 2008), November in south-western Britain (Evans, 1953;Orton et al, 1956;Bowman & Lewis, 1986) and northern France (Fisher-Piètte, 1948;Choquet, 1966), and November-December in northern Spain (Ibañez et al, 1986;Othaitz, 1994) and northern Portugal (Guerra & Gaudêncio, 1986; this study). The present work provided the first description of the reproductive cycle of Patella rustica on the Portuguese coast.…”

“…Reproductive cycles of Patella in the north-eastern Atlantic region are particularly well known in the British Isles for Patella vulgata Linnaeus, 1758 (e.g. Orton et al , 1956; Thompson, 1980; Bowman & Lewis, 1986; Delany et al , 2002), but also for Patella depressa Pennant, 1777 (Orton & Southward, 1961; Moore et al , 2007) and Patella ulyssiponensis Gmelin, 1791 (Evans, 1953; Thompson, 1979; McCarthy et al , 2008). To a lesser extent, northern France (Fisher-Piètte, 1948; Choquet, 1966) and Spain (Othaitz, 1994) have also been covered.…”

The reproductive cycles of four limpet species, Patella depressa, Patella ulyssiponensis, Patella vulgata and Patella rustica are described for several locations in northern and central Portugal. Patella depressa and P. ulyssiponensis displayed almost continual gonad activity, with two main spawning periods, September–January and March–June, and minor spawning events dispersed throughout the year. Patella vulgata and P. rustica exhibited highly synchronized reproductive cycles, with well-defined breeding and resting periods. Gonad development in P. vulgata started in September and spawning took place from November–December to March. In P. rustica development started in June and spawning occurred from September–October to December–January. Compared to the 1980s these results suggest that breeding periods are becoming longer in southern species and shorter in northern species.

“…A number of studies have been conducted in order to investigate the reproductive cycles of Patella congeners, e.g. Patella vulgata (Orton et al , 1956; Thompson, 1980; Bowman & Lewis, 1986; Delany et al , 2002; McCarthy et al , 2008; Ribeiro et al , 2009), Patella depressa (Orton & Southward, 1961; Bowman & Lewis, 1986; Brazão et al , 2003; Moore et al , 2007; Ribeiro et al , 2009), Patella ulyssiponensis (Evans, 1953; Thompson, 1979; Bowman & Lewis, 1986; Guerra & Gaudêncio, 1986; McCarthy et al , 2008; Ribeiro et al , 2009), Patella caerulea (Frenkiel, 1975; Belkhodja et al , 2011) and Patella ferruginea (Espinosa et al , 2006; Guallart et al , 2013). The reproductive cycle of P. rustica has been previously described on the Algerian coast of the Mediterranean Sea (Frenkiel, 1975), and on the Basque (Othaitz, 1994) and Portuguese coasts of the north-east Atlantic (Ribeiro et al , 2009), based only on macroscopic examination of gonads and the staging scheme developed by Orton et al (1956).…”

On the reproduction of the Mediterranean keystone limpetPatella rustica: histological overview

et al. 2014

The reproductive cycle of the high shore limpet Patella rustica is described based on histological analysis as the primary method of staging gonad development. Sex-ratios, shell length at sexual maturity, gonad developmental stages, mean gonad index and oocyte size were investigated. Males and females were found to differ in size distribution, with females becoming more prevalent from ~28 mm onwards. The estimated shell length at which 50% of males were sexually mature was 13.1 mm. Patella rustica has only one reproductive cycle per year with a spawning peak between November and December for both sexes, and gonad redevelopment from January. First data on the size–frequency analysis of oocytes for this species are also presented, concurring with the qualitative analysis of the gonad developmental stages. This study presents updated information on the reproductive cycle of this keystone species and provides the first account of the reproductive biology of P. rustica in the Adriatic Sea.

“…Identification of the specimens at the species level was based on the morphology of the radula pluricuspid teeth and of the shell (Fig. 1), by comparison with data reported in the literature (Evans 1947, 1953, Fischer-Piette and Gaillard 1959, Christiaens 1973, Fretter and Graham 1994, as previously described (Cabral 2003).…”

Specimens of Patella intermedia, Patella rustica, Patella ulyssiponensis, and Patella vulgata were analyzed for shell and radula characteristics. Shell growth in P. rustica and P. ulyssiponensis was basically isometric, indicating that shell shape was constant during growth. On the contrary, shell growth in P. intermedia and P. vulgata was positively allometric, indicating that as shells increased in size, the base became more circular and the cone more centred and relatively higher. Radula relative size increased in the order P. ulyssiponensis, P. vulgata, P. intermedia and P. rustica, and had negative allometric growth in all species, indicating that radula grew less as shell increased in size. Data reported in the literature estimated that the lowest risk of dislodgment for a limpet is associated with a centred apex, and a (shell height)/(shell length) or (shell height)/(shell width) ratio of ca. 0.53. However, as reported for other limpets, in all four studied Patella species, shells were more eccentric and flat than this theoretical optimum. Data reported in the literature indicated that, in limpets, decreasing the (shell base perimeter)/(shell volume) or (shell surface area)/(shell volume) ratios by increasing size results in lower soft body temperature and desiccation. In the present study, P. rustica shells displayed the lowest ratios, and P. ulyssiponensis shells, the highest. Considering that the former species lives at high shore levels, and the latter species at low levels, it appeared that shell shape in European Atlantic limpets can be directly related to resistance to desiccation and high temperature stresses. Radula relative size (in relation to shell height) also increased with increasing level in the shore, suggesting that this might be due to a decreasing abundance of algae with increasing shore level
