Venom in Furs: Facial Masks as Aposematic Signals in a Venomous Mammal
The function of colouration in animals includes concealment, communication and signaling, such as the use of aposematism as a warning signal. Aposematism is unusual in mammals, and exceptions help us to understand its ecology and evolution.

« A sauts et à gambades » : de cette formule des Essais, la critique a souvent conclu au décousu de leur écriture. Notre travail montre qu'il n'en est rien dans de nombreux chapitres des Essais, en s'appuyant sur l'idée de « cryptique » chez Ramus (Dialectique, 1555) et Canaye (L'Organe, 1589) et sur le concept rhétorique de ductus ou progression du ...

The origin and evolution of Dolichoderinae, a dominant ant clade (Hymenoptera: Formicidae)
The phylogeny of Dolichoderinae is inferred from phylogenomic data for the first time, based on 131 terminals representing all extant genera except Ecphorella, with divergence dating and time‐stratified historical biogeography. Novel phylogenetic relationships facilitate a new informal classification of genus groups, the erection of Paranillidris gen ...

Functional and Trophic Structuring of Micronektonic Fishes in the Northeast Atlantic
Sharp vertical gradients structure the functional and trophic organization of mesopelagic micronektonic fishes, driving a transition from migratory, surface‐linked assemblages in upper layers (0–700 m) to resident communities adapted to deep, low‐light environments (> 700 m).

Female mimicry by males is a widespread phenomenon in several taxa and may be involved in aggression avoidance or facilitated access to resources. In early developmental stages, female mimicry may be a mechanism involved in signalling sexual maturity or,

Cephalopods have two main defence strategies: the first consists on reducing the odds of being detected by a predator, while the second focuses on avoiding capture.

Incubating parents serve as visual cues to predators in Kentish plover (Charadrius alexandrinus).
Ground-nesting birds face many challenges to reproduce successfully, with nest predation being the main cause of reproductive failure. Visual predators such as corvids and egg-eating raptors, are among the most common causes of nest failure; thus ...

We conducted a study on interpopulation variation of colour patterns in two congeneric chameleon species, which have an analogous life history. Both species are able to rapidly change colour pattern, and their context-dependent colour patterns often vary

Molecular crypsis by pathogenic fungi using human factor H. A numerical model
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
