Evolution of the Cdk4/6-Cdkn2 system in invertebrates. [PDF]

Genes Cells
Hypothesis on the evolution of the Cdkn2 locus. (a) Loss of Cdkn2 occurred multiple times. (b) Evolution of microsynteny at the Cdkn2 locus. Cdkn2e is a hypothetical transient gene. Abstract The cell cycle is driven by cyclin‐dependent kinases (Cdks). The decision whether the cell cycle proceeds is made during G1 phase, when Cdk4/6 functions.

An Eocene orthocone from Antarctica shows convergent evolution of internally shelled cephalopods. [PDF]

PLoS ONE, 2017
BackgroundThe Subclass Coleoidea (Class Cephalopoda) accommodates the diverse present-day internally shelled cephalopod mollusks (Spirula, Sepia and octopuses, squids, Vampyroteuthis) and also extinct internally shelled cephalopods.

Analysis of catch rates of LED lamps using on the falling-net fishing vessels in South China Sea. [PDF]

PLoS ONE
Falling nets are a type of fishing gear that appeared and developed rapidly in the northern of South China Sea in the early 1990s. We have developed Light-emitting diode (LED) fishing lamps to replace metal halide (MH) lamps that reduce fuel consumption ...

Genus-level phylogeny of cephalopods using molecular markers: current status and problematic areas [PDF]

PeerJ, 2018
Comprising more than 800 extant species, the class Cephalopoda (octopuses, squid, cuttlefish, and nautiluses) is a fascinating group of marine conchiferan mollusks.

Development of a DNA Metabarcoding Method for the Identification of Crustaceans (Malacostraca) and Cephalopods (Coleoidea) in Processed Foods [PDF]

Foods
Seafood is a valuable commodity with increasing demand, traded for billions of USD each year. The volatility in supply chains and fluctuating prices contribute to the susceptibility of the seafood market to food fraud.

Cautionary tales on the use of proxies to estimate body size and form of extinct animals. [PDF]

Ecol Evol
Reconstructing the body size and form of extinct animals is of vital importance to our understanding of macroevolution and palaeontology. This is often done using anatomical proxies where extinct species are known only from fragmentary remains. However, there are many limitations influencing the selection of proxy taxa that are frequently overlooked ...

Orthoceratoid and coleoid cephalopods from the Middle Triassic of Switzerland with an updated taxonomic framework for Triassic Orthoceratoidea [PDF]

Swiss Journal of Palaeontology
Orthoconic cephalopods are subordinate, but persistent, widespread and regionally abundant components of Triassic marine ecosystems. Here, we describe unpublished specimens from the Anisian (Middle Triassic) Besano Formation at Monte San Giorgio ...

A general model fitting coleoid cephalopod growth as a function of time and temperature to a single curve

Aquaculture, Fish and Fisheries, Volume 3, Issue 6, Page 539-549, December 2023., 2023
1. A novel general model has been developed to fit biomass growth data of coleoid cephalopods as a function of time and temperature. 2. The model calculates when the growth curve inflection occurs and when the maximum size is reached. 3. When the model was parameterized as a function of temperature on Octopus maya fitness, it confirmed the optimal ...

Cephalopods in the diet of Risso's dolphin (Grampus griseus) from the Mediterranean Sea: A review

Marine Mammal Science, Volume 38, Issue 2, Page 725-741, April 2022., 2022
Abstract The Risso's dolphin, Grampus griseus, is a deep‐sea cetacean with a predominantly teuthophagous diet. Its distribution in the northwest Mediterranean is generally in deeper waters, but there is little information on diet or feeding areas. To extend knowledge of the diet of G.

Large‐Scale Tectonic Forcing of the African Landscape

Journal of Geophysical Research: Earth Surface, Volume 126, Issue 12, December 2021., 2021
Abstract Successful inverse modeling of observed longitudinal river profiles suggests that fluvial landscapes are responsive to continent‐wide tectonic forcing. However, inversion algorithms make simplifying assumptions about landscape erodibility and drainage planform stability that require careful justification.
