Developmental phenotypic plasticity in a marsupial.
Climate change is likely to substantially affect the distribution ranges of species. However, little is known about how different mammalian taxa respond morphologically and physiologically to a rapid change of climate. Our objective was to provide the first quantitative data on the effect of continuous cold exposure during development on morphological and functional variables of a marsupial. Fa...
متن کاملPhenotypic plasticity and developmental innovations in nematodes.
Developmental plasticity has been implicated as a facilitator for phenotypic diversification, but the molecular mechanisms controlling it are largely unknown. We review recent comparative analyses in non-Caenorhabditis nematodes that display polyphenisms in larval development, mouth morphology and reproductive mode. Some of the challenges ahead will be to connect how these phenotypic traits are...
متن کاملWhere Environment Meets Cognition: A Focus on Two Developmental Intellectual Disability Disorders
One of the most challenging questions in neuroscience is to dissect how learning and memory, the foundational pillars of cognition, are grounded in stable, yet plastic, gene expression states. All known epigenetic mechanisms such as DNA methylation and hydroxymethylation, histone modifications, chromatin remodelling, and noncoding RNAs regulate brain gene expression, both during neurodevelopmen...
متن کاملThe development of phenotypic plasticity: where biology and psychology meet.
‘‘The mechanisms that underlie much of behavioral evolution may reside in the processes studied by developmental psychobiologists . . . ’’ Michel & Moore, 1995, p. 178. The counterpart in biology of developmental psychobiology is phenotypic plasticity, or the process by which the internal milieu and the environment induce different phenotypes from a given genotype (Sarkar, 1999; Sarkar & Fuller...
متن کاملEvolution, Development and Environment Toward Adaptation through Phenotypic Plasticity and Exploitation of External Information
Biological organisms have an inherent ability to respond to environmental changes. The response can emerge as organisms that can develop into structural and behavioural different phenotypes. To achieve such properties in an artificial developmental setting external environmental information is included in the gene regulation of the developmental model. This implies interplay between evolution, ...
