Phylogeography and biogeography concordance in the marine gastropod Crepipatella dilatata (Calyptraeidae) along the southeastern Pacific coast.
The biogeography and phylogeography concordance hypothesis suggests that the same factors, for instance physical barriers or environmental gradients, shape both species assemblages and intraspecific genetic structure. In the marine realm, previous studies have however suggested that phylogeographic patterns are also explained by the life-history strategy of the species. However, evidence is con...
متن کاملConfirmation of the identification and establishment of the South American slipper limpet Crepipatella dilatata (Lamark 1822) (Caenogastropoda: Calyptraeidae) in Northern Spain
Calyptraeid gastropods have been introduced frequently in bays and ports around the world, and have become rampantly invasive in several cases. Here we confirm the identification and establishment of a recently-detected population of Crepipatella in northern Spain. Because their shells do not have many diagnostic features, introductions of calyptraeids are often accompanied by confusion about t...

15 صفحه اولEffects of Low Salinity on Adult Behavior and Larval Performance in the Intertidal Gastropod Crepipatella peruviana (Calyptraeidae)
Shallow-water coastal areas suffer frequent reductions in salinity due to heavy rains, potentially stressing the organisms found there, particularly the early stages of development (including pelagic larvae). Individual adults and newly hatched larvae of the gastropod Crepipatella peruviana were exposed to different levels of salinity stress (32(control), 25, 20 or 15), to quantify the immediat...
متن کاملObservations on the Embryonic Development of Freshwater Pulmonate Snail Lymnaea Acuminata (lamarck, 1822) (gastropoda: Mollusca)
Molluscs have played important role in strengthening our knowledge of fundamental processes in developmental biology, with the common pond snail Lymnaea stagnalis contributing greatly to this body of literature for nearly a century (Gatenby, 1919; Sturtevant, 1923; Canton and Sloof, 1977). The morphological, morphometric and behavioral aspects of development of L. stagnalis have been well docum...
