Littorina (Neritrema) saxatilis salvati (var.) The species Littorina saxatilis are one of many gastropod ‘snails’ on the rocky shore.Most of these gastropods tend to have similar requirements for survival. Walay nalista nga matang nga sama niini. In experiments Littorina littorea were able to tolerate temperatures down to -8 °C for 8 days (Murphy, 1983). Littorina saxatilis (Olivi, 1972) is one of the most abundant snail species on intertidal rocky shores along the North Atlantic coast. Los análisis de ADN muestran que hay significativa diferenciación genética - aunque no la suficiente para considerarla una sp. First identified in the 1700s, it has been misidentified as a new species 112 times. It lacks pelagic larvae, has a very variable morphology, and shows strong population structure in allozymes ( Janson, 1987 ; Johannesson, Johannesson & Lundgren, 1995 ), RAPD ( Johannesson et al ., 2004 ), and microsatellite DNA markers ( Panova, Hollander & Johannesson, 2006 ).

The North Atlantic intertidal gastropod, Littorina saxatilis (Olivi, 1792), exhibits extreme morphological variation between and within geographic regions and has become a model for studies of local adaptation; yet a comprehensive analysis of the species' phylogeography is lacking. Tony Kess, Juan Galindo and Elizabeth G. Boulding, Genomic divergence between Spanish Littorina saxatilis ecotypes unravels limited admixture and extensive parallelism associated with population history, Ecology and Evolution, 8, 16, (8311-8327), (2018).

Distribution of Littorina saxatilis 37 Distribution and density of Carcinus maenas 40 Chapter 3 - Optimality of feeding by Carcinus maenas on Littorina saxatilis. Syst. Population differences were measured in the tolerance of Littorina saxatilis from sites around the Isle of Man, to acute exposure to zinc, lead, copper and cadmium. Littorina saxatilis is also a characterizing species but it is mobile, not dependent on Verrucaria maura for habitat, and common in the upper to lower littoral fringe, the upper eulittoral and upper shore rockpools and crevices. Effects of latitudinal cold adaptation and cold acclimation on metabolic rates and aerobic scope were studied in the eurythermal marine gastropod Littorina saxatilis from temperate North Sea and sub-arctic White Sea areas.
