Consensus and Confusion in Molluscan Trees: Evaluating Morphological and Molecular Phylogenies [PDF]

, 2014
Mollusks are the most morphologically disparate living animal phylum, they have diversified into all habitats, and have a deep fossil record. Monophyly and identity of their eight living classes is undisputed, but relationships between these groups and ...

Charting Evolution’s Trajectory: Using Molluscan Eye Diversity to Understand Parallel and Convergent Evolution [PDF]

, 2008
For over 100 years, molluscan eyes have been used as an example of convergent evolution and, more recently, as a textbook example of stepwise evolution of a complex lens eye via natural selection. Yet, little is known about the underlying mechanisms that

Occurrence of chitons (Mollusca, Polyplacophora) in estuaries: first records in Brazil [PDF]

Check List
Chitons are molluscs with scarce world records in estuaries. In the present study, we provide the first records of two species of Polyplacophora in the Coreaú River estuary, Camocim, Ceará, Brazil: Ischnochiton striolatus ...

How the mollusc got its scales: convergent evolution of the molluscan scleritome [PDF]

, 2015
Radiation of dramatically disparate forms among the phylum Mollusca remains a key question in metazoan evolution, and requires careful evaluation of homology of hard parts throughout the deep fossil record. Enigmatic early Cambrian taxa such as Halkieria

Tightening the girdle: phylotranscriptomics of Polyplacophora

Journal of Molluscan Studies, 2021
ABSTRACT The phylogenetic relationships within the molluscan class Polyplacophora (chitons) have been studied using morphology, traditional Sanger markers and mitogenomics, but, to date, no analysis has been carried out using transcriptomic and genome-wide data.

Temperature and Prey Availability Drive Seasonal Variations in Diet, Abundance and Condition of Forsterygion lapillum Across Two Coastal Habitats

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study investigated how temperature, turbidity and prey availability affect the diet, body condition and abundance of F. lapillum in two coastal ecosystems. Results showed seasonal and spatial variation, with body condition, abundance and gut volume positively correlated with warmer temperatures but not with turbidity.

Extent and toxicity of contaminated marine sediments in Southeastern Florida [PDF]

, 2004
Thirty sites were sampled in southern Biscayne Bay and Manatee Bay in December 1999 to determine the extent of toxicity in sediments. Analyses and assays included: pesticides and phenols in seawater; chemical contaminants in sediment; amphipod mortality,
