Left–right asymmetry of the visual system in the scallop Nodipecten nodosus (Bivalvia: Pectinidae)

Journal of Molluscan Studies, 2023
ABSTRACT Left–right asymmetries are consistent differences between the left and right sides and represent an intriguing feature of molluscan morphology. Interestingly, external asymmetries, such as inequivalve shells, are often coupled with lateralization in the nervous system, which often includes functional and structural ...

Understanding the molecular epidemiology of the footrot pathogen Dichelobacter nodosus to support control and eradication programs [PDF]

, 2010
The Gram-negative anaerobe Dichelobacter nodosus is the primary etiologic agent of ovine footrot. Few studies of the genetic diversity and epidemiology of D. nodosus have been done, despite the economic cost and welfare implications of the disease.

Growth and survival of the tropical scallop Lyropecten (Nodipecten) nodosus maintained in suspended culture at three depths

Aquaculture, 1998
Abstract We examined growth and survival of juvenile Lyropecten (Nodipecten) nodosus, measuring 9.4 mm in shell height, which were placed in mid-December 1993 in pearl nets at 8, 21 and 34 m in depth at Turpialito in the Golfo de Cariaco, Venezuela. The mean growth rate in shell height during the first 5 months varied inversely with depth (10.0, 8.5 ...

The role of the environment in transmission of Dichelobacter nodosus between ewes and their lambs [PDF]

, 2015
Dichelobacter nodosus (D. nodosus) is the essential causative agent of footrot in sheep. The current study investigated when D. nodosus was detectable on newborn lambs and possible routes of transmission. Specific qPCR was used to detect and quantify the

Influence of environmental variables and reproduction on the gonadal fatty acid profile of tropical scallop Nodipecten nodosus

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2010
We examined the influence of the reproductive cycle and environmental variables on the gonadal fatty acid profile in the tropical scallop Nodipecten nodosus. Individuals from a natural population in north-eastern Venezuela (Caribbean Sea) were sampled monthly during one year.

REMOTE SETTING OF Nodipecten nodosus (Linnaeus 1758) LARVAE

Boletim do Instituto de Pesca, 2020
The present study aimed to evaluate the growth and survival of Nodipecten nodosus larvae grown in a remote settlement system. Two forms of transport were tested, one in a humid/wet, environment and one submerged in seawater, with a control treatment maintained at the Laboratory of Marine Mollusks (LMM).

Exposure to phenanthrene and depuration: Changes on gene transcription, enzymatic activity and lipid peroxidation in gill of scallops Nodipecten nodosus [PDF]

Aquatic Toxicology, 2016
Understanding the mechanism of phenanthrene (PHE) biotransformation and related cellular responses in bivalves can be an important tool to elucidate the risks of polycyclic aromatic hydrocarbons (PAHs) to aquatic organisms. In the present study it was analyzed the transcriptional levels of 13 biotransformation genes related to cytochrome P450 (CYP ...
