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

Chitinobelus acifer Fischer 1981, ein Belemnoteuthide (Coleoidea) mit Epirostrum
, 1983 The "unusual belemnite" Chitinobelus acifer FISCHER with an "almost purely organic, pinlike epirostrum" and a "calcitic primary rostrum" (FISCHER 1981: 142) is attributed to the order Belemnoteuthida STOLLEY 1919. Carbonate diagenesis suggests that ortho- and epirostrum, were originally aragonitic.

The Xihpoteuthididae Bather, 1892 (Aulacocerida, Coleoidea). An outline classification.
, 1999 Problems in the classification of the Xiphoteuthididae have been recently addressed (Mariotti and Pignatti, 1992, 1994, 1996; Pignatti and Mariotti, 1996), but a critical revision is still lacking, owing mainly to their incomplete fossil record. The following outline of a classification summarizes diagnostic characters, taxonomie relationships, and ...

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.
