Intertidal ostracod (Crustacea: Ostracoda) abundance and assemblage structure within and between four shores in north-east England (1999)
Journal Article
Hull, S. L. (1999). Intertidal ostracod (Crustacea: Ostracoda) abundance and assemblage structure within and between four shores in north-east England. Journal of the Marine Biological Association of the UK, 79(6), 1045-1052. https://doi.org/10.1017/S0025315499001289

Triplicate samples of rockpool algae were collected at each of three tidal elevations (upper, mid and low) from four shores on the north-east coast of England. Two moderately exposed (Ravenscar, the exposed shore at Filey Brigg), and two moderately s...

Reproduction in four populations of brooding periwinkle (Littorina) at Ravenscar, North Yorkshire: adaptation to the local environment? (1999)
Journal Article
Hull, S. L., Grahame, J., & Mill, P. J. (1999). Reproduction in four populations of brooding periwinkle (Littorina) at Ravenscar, North Yorkshire: adaptation to the local environment?. Journal of the Marine Biological Association of the UK, 79(5), 891-898. https://doi.org/10.1017/s0025315499001058

The current study examines the reproductive patterns found within four ovoviviparous, brooding periwinkle populations on one shore in the north-east coast of England; the boulder dwelling populations Littorina saxatilis H (upper-shore form with thin...

Assortative mating between two distinct micro-allopatric populations of Littorina saxatilis (Olivi) on the northeast coast of England (1998)
Journal Article
Hull, S. L. (1998). Assortative mating between two distinct micro-allopatric populations of Littorina saxatilis (Olivi) on the northeast coast of England. Hydrobiologia, 378(1/3), 79-88. https://doi.org/10.1023/a%3A1003237521419

Size assortative mating is a common invertebrate mating pattern and is usually accompanied by male and female sexual selection, and these three behaviours can contribute to reproductive isolation. Two distinct populations of the marine prosobranch Li...

Morphological divergence and evidence for reproductive isolation in Littorina saxatilis (Olivi) in northeast England (1996)
Journal Article
Hull, S., Grahame, J., & Mill, P. (1996). Morphological divergence and evidence for reproductive isolation in Littorina saxatilis (Olivi) in northeast England. Journal of Molluscan Studies, 62(1), 89-99. https://doi.org/10.1093/mollus/62.1.89

Current work at Old Peak (Ravenscar) on the northeast coast of England indicates that boulder-dwelling Lutonna saxatilis (Olvi) comprise at least two distinct forms, inhabiting high- and mid-shore boulders Using multivariate morphometrics we show tha...

Littorina neglecta Bean: ecotype or species? (1995)
Journal Article
Grahame, J., Mill, P., Hull, S., & Caley, K. (1995). Littorina neglecta Bean: ecotype or species?. Journal of Natural History, 29(4), 887-899. https://doi.org/10.1080/00222939500770321

The taxonomic status of the littoral prosobranch Littorina neglecta has been investigated using animals from the northeast coast of England. Rough periwinkles were collected from barnacle-covered rock platforms near the northern (Ness Point) and sout... Read More about Littorina neglecta Bean: ecotype or species?.
