Chemical Composition of the Eggs of the Freshwater Turtle Phrynops hilarii (Chelidae: Testudines) [PDF]
At oviposition, amniote eggs contain all the nutrients required for complete neonate tissue development. For reptiles and birds, the egg yolk is the main embryonic energy source and is composed predominantly of proteins and lipids, while also providing ...

ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

The role of two anatomically separate olfactory bulbs in shark food odor tracking [PDF]
Most sharks have well-developed olfactory systems and depend to a large degree on odor information to locate food, home and navigate, and possibly detect predators and mates.

Overview of the effects of Pax1‐SAR deletion on gene expression, IVD degeneration, and resultant scoliotic‐like curvature between sexes. Proposed mechanism of sex‐dependent changes in gene expression in females (right) and males (left), resulting in sex‐dependent disc degeneration and scoliotic phenotypes.

GRKs and arrestins: Nomenclature and functions in GPCR‐dependent and ‐independent signalling
G protein‐coupled receptor (GPCR) kinases (GRKs) and arrestins play a critical role in the regulation of GPCR signalling. Historic names of mammalian GRKs were replaced by systematic ones in the 1990s; however, both kinds of names are currently in use for mammalian arrestins.

Neurophysiological responses to stressful motion and anti-motion sickness drugs as mediated by the limbic system [PDF]
Performance is characterized in terms of attention and memory, categorizing extrinsic mechanism mediated by ACTH, norepinephrine and dopamine, and intrinsic mechanisms as cholinergic.

Heterokairic Genes and the Eco‐Evo‐Devo of Timing
Heterokairic genes as the bridge (Heterokairic Pathways?): Heterokairic genes are heterochronic regulators whose activity is modulated by environmental conditions. External cues (e.g., temperature, nutrition, oxygen, density: yellow box) are sensed (yellow arrows) and converted into endocrine and metabolic signals (purple box and arrow into fish's ...
