Aposematic signaling and seasonal variation in dorsal pelage in a venomous mammal

Ecology and Evolution, 2021
In mammals, colouration patterns are often related to concealment, intraspecific communication, including aposematic signals, and physiological adaptations.

Decoding the invisible forces of social connections

Frontiers in Integrative Neuroscience, 2012
By its 20th anniversary, social neuroscience has witnessed an incredible rise in the number of studies demonstrating the effects of perceived social isolation (e.g., loneliness, ostracism), and inversely, the beneficial effects of social bonding (e.g ...

Coexistence Patterns Between Ants And Spiders In Grassland Habitats

Sociobiology, 2014
The ecological importance of both ants and spiders is well known, as well as the relationship between certain spiders and ants. The two main strategies ˗ myrmecomorphy (ant-mimicking) and myrmecophagy (ant-eating) ˗ that connect spiders to ants have been

Hybridization constrains the evolution of mimicry complexes in woodpeckers

Journal of Avian Biology
The evolution of interspecific mimicry does not always result in perfect resemblance between mimics and models. Differences between members of a mimicry complex can be explained by genetic or developmental constraints.

Ploidy differences represent an impassable barrier for hybridization. Is there an exception among botiid loaches (Cypriniformes: Botiidae)?

Frontiers in Marine Science, 2015
One of the most efficient mechanisms to keep animal lineages separate is a difference in ploidy level, since hybrid offspring from parents with different ploidy level are generally sterile.

Neural networks for action representation underlying automatic mimicry: A functional magnetic-resonance imaging and dynamic causal modeling study

Frontiers in Human Neuroscience, 2012
Automatic mimicry is based on the tight linkage between motor and perception action representations in which internal models play a key role. Based on the anatomical connection, we hypothesized that the direct effective connectivity from the posterior ...

Molecular mimicry as a mechanism of viral immune evasion and autoimmunity

Nature Communications
Mimicry of host protein structures, or ‘molecular mimicry’, is a common mechanism employed by viruses to evade the host’s immune system. Short linear amino acid (AA) molecular mimics can elicit cross-reactive antibodies and T cells from the host, but the

Human mimicry and Imitation: the case of Biomimetics

Aisthesis, 2017
Defining biomimetics (§ 1) as the imitation of models, systems and elements of nature for the purpose to solve human complex problems, the essay considers (§ 2) some examples of that activity, like display technologies, and nanoscientific innovations ...

Proto-Acting as a New Concept: Personal Mimicry and the Origins of Role Playing

Humanities, 2017
Proto-acting is introduced here as a new concept that refers to a set of processes that are intermediate between everyday role playing (in the Erving Goffman sense) and dramatic acting.
