One of the most adaptive facultative anaerobes among vertebrates is the freshwater turtle, Trachemys scripta elegans. Upon a decrease in oxygen supply and oxidative phosphorylation, these turtles are able to reduce their metabolic rate and recruit anaerobic glycolysis to meet newly established ATP demands. Within the glycolytic pathway, aldolase enzymes cleave fructose-1,6-bisphosphate to trios...

Aim To critically review the status of the green sea turtle ( Chelonia mydas ) using the best available scientific studies as there is a prevailing view that this species is globally endangered and its marine ecosystem functions compromised. Location Ogasawara (Japan), Hawaii (USA), Great Barrier Reef (Australia), Florida (USA), Tortuguero (Costa Rica). Methods We compiled seasonal nesting acti...

Little is known about how specific anthropogenic hazards affect the biology of organisms. Quantifying the effect of regional hazards is particularly challenging for species such as sea turtles because they are migratory, difficult to study, long lived, and face multiple anthropogenic threats. Expert elicitation, a technique used to synthesize opinions of experts while assessing uncertainty arou...

The TURTLE UML profile and the open source toolkit TTool define a formal modeling and verification framework for communicating embedded systems design. The paper extends TURTLE and TTool with network calculus techniques. Dimensioning diagrams enable system dimensioning prior to usual object-oriented design and facilitates formal verification of design models. The paper uses a video-conferencing...

Constraint imperative programming languages combine declarative constraints and imperative language features into an integrated programming language. The language Turtle supports these programming paradigms and additionally integrates functional programming with higher-order functions and algebraic data types. This paper describes the implementation of Turtle, consisting of a compiler, a run-ti...

121 COVER Skeletons of turtle, chicken, and mouse. The turtle body plan is unusual in that the ribs are transformed into a carapace, and the scapula, situated outside the ribs in other animals, is found inside the carapace. A report on page 193 explains the evolutionary origin of this inside-out skeletal morphology.
