Molecular crypsis by pathogenic fungi using human factor H. A numerical model.
PLoS ONE, 2019 Molecular mimicry is the formation of specific molecules by microbial pathogens to avoid recognition and attack by the immune system of the host. Several pathogenic Ascomycota and Zygomycota show such a behaviour by utilizing human complement factor H to

Ecology and Evolution, 2023 Camouflage is a common trait enabling animals to avoid detection by predators and prey. Patterns such as spots and stripes are convergent across carnivore families, including felids, and are hypothesized to have adaptive value through camouflage.

Is countershading camouflage robust to lighting change due to weather? [PDF]
, 2018 Countershading is a pattern of coloration thought to have evolved in order to implement camouflage. By adopting a pattern of coloration that makes the surface facing towards the sun darker and the surface facing away from the sun lighter, the overall ...

Dissociating the effect of disruptive colouration on localisation and identification of camouflaged targets [PDF]
, 2018 Disruptive camouflage features contrasting areas of pigmentation across the animals’ surface that form false edges which disguise the shape of the body and impede detection.

Crypsis via leg clustering: twig masquerading in a spider [PDF]
Royal Society Open Science, 2015 The role of background matching in camouflage has been extensively studied. However, contour modification has received far less attention, especially in twig-mimicking species.

La geometría de visualización afecta el dicromatismo sexual y la conspicuidad de la coloración del plumaje no iridiscente de Tersina viridis [PDF]
, 2016 Some types of plumage color are difficult to characterize spectrophotometrically because the properties of the reflected light change with viewing geometry (i.e.

Changeable camouflage: how well can flounder resemble the colour and spatial scale of substrates in their natural habitats? [PDF]
Royal Society Open Science, 2017 Flounder change colour and pattern for camouflage. We used a spectrometer to measure reflectance spectra and a digital camera to capture body patterns of two flounder species camouflaged on four natural backgrounds of different spatial scale (sand, small

Clutch Destruction by Common Cuckoos (<i>Cuculus canorus</i>) During the Laying Stage of Vinous-Throated Parrotbills (<i>Sinosuthora webbiana</i>): First Video Evidence. [PDF]
Ecol EvolWe present the first video‐documented evidence of clutch destruction by Common Cuckoos during the laying stage of Vinous‐throated Parrotbills. This behavior, observed across five cases, led to complete clutch loss and host desertion. Our findings expand the known timeline of brood parasite aggression and offer new insights into host–parasite ...

THE ORIGIN OF POLYMORPHIC CRYPSIS IN A HETEROGENEOUS ENVIRONMENT [PDF]
Evolution, 2010 Polymorphic crypsis has been observed in several taxa, but has, until now, lacked a firm theoretical understanding. How does a single morph, well camouflaged in one type of habitat, evolve crypsis in another, not isolated, habitat? We here analyze a model of one prey species living in two different habitats connected by passive dispersal.
