A self tuning sliding window method for detecting phenotype linked regional poly-methylation architecture in sparse wildlife methylomes
Published: 2026-06-26
Subjects: Bioinformatics, Cellular and Molecular Physiology, Comparative and Evolutionary Physiology, Evolution, Genetics and Genomics, Marine Biology, Other Ecology and Evolutionary Biology
Despite featuring extreme physiological adaptations integration of wildlife species into the modern ‘omics’ frameworks are limited due to the sparsity in the data. To address the sparsity limitation a self-tuning sliding-window framework was developed for the identification of the regional poly-CpG methylation architecture associated with phenotypic traits. Under the framework the iteratively [...]
In-silico evaluation of aspartate therapy for lactic acidosis in Alligator mississippiensis
Published: 2026-06-23
Subjects: Biochemistry, Cellular and Molecular Physiology, Comparative and Evolutionary Physiology, Computational Biology, Systems and Integrative Physiology Life Sciences
Hyperlactatemia, and/or lactic acidosis, is a common complication in wildlife due to the sensitivity of these species to capture induce complications. The treatment of lactic acidosis in humans is equally as controversial as in veterinary medicine. Stabilisation of blood pH during lactic acidosis is difficult to achieve. Crocodilians, such as the American Alligator (Alligator mississippiensis), [...]
Toxin resistance mechanisms span biological scales in the Royal Ground Snake (Colubridae: Erythrolamprus reginae)

Exposure to multiple toxic compounds imposes selective pressures across biological levels. There are several known toxin resistance mechanisms–such as behavioral avoidance, metabolic detoxification, and target-site insensitivity but an integrative approach to consider multiple toxins and resistance strategies. Predators of amphibians, for example, must counteract multiple chemicals secreted by [...]
Abiogenesis as the origin of adaptive evolution. An alternative to the Oparin-Haldane model

The emergence of life from non-living matter remains one of the most profound unresolved questions in natural philosophy. Current paradigms largely inherit the Oparin-Haldane assumption that abiogenesis is preceded by a prolonged accumulation of traits through both nonadaptive (e.g. self-organisation) and adaptive (i.e. natural selection) processes. Yet this raises a legitimate question: how can [...]
A rapidly expanding house of cards: the silent loss of cell physiology hampers marine biosciences
Published: 2021-11-23
Subjects: Biochemistry, Biochemistry, Biophysics, and Structural Biology, Cellular and Molecular Physiology, Comparative and Evolutionary Physiology, Life Sciences, Marine Biology, Physiology, Systems and Integrative Physiology Life Sciences
Perspective: An ongoing loss of expertise on the biochemistry and physiology of marine organisms hampers our understanding of biological mechanisms upon rapidly growing “-omics” approaches reply -ultimately affecting our ability to predict organismal responses to climate change.
Endocrinology of thermoregulation in birds in a changing climate
Published: 2019-09-09
Subjects: Cellular and Molecular Physiology, Ecology and Evolutionary Biology, Endocrinology, Life Sciences, Physiology
The ability to maintain a (relatively) stable body temperature in a wide range of thermal environments is a unique feature of endotherms such as birds. Endothermy is acquired and regulated via various endocrine and molecular pathways, and ultimately allows wide aerial, aquatic, and terrestrial distribution in variable environments. However, due to our changing climate, birds are faced with [...]
