Evolutionary transformation of mouthparts from particle-feeding to piercing carnivory in Viper copepods: Review and 3D analyses of a key innovation using advanced imaging techniques
Novel feeding adaptations often facilitate adaptive radiation and diversification. But the evolutionary origins of such feeding adaptations can be puzzling if they require concordant change in multiple compone... (Source: Frontiers in Zoology)

Artificial selection for male winners in the Siamese fighting fish Betta splendens correlates with high female aggression
In Southeast Asia, males of the Siamese fighting fish Betta splendens have been selected across centuries for paired-staged fights. During the selection process, matched for size males fight in a small tank until... (Source: Frontiers in Zoology)

Morphology of the nervous system of monogonont rotifer Epiphanes senta with a focus on sexual dimorphism between feeding females and dwarf males
Monogononta is a large clade of rotifers comprised of diverse morphological forms found in a wide range of ecological habitats. Most monogonont species display cyclical parthenogenesis, where generations of as... (Source: Frontiers in Zoology)

Landscape homogenization due to agricultural intensification disrupts the relationship between reproductive success and main prey abundance in an avian predator
Selecting high-quality habitat and the optimal time to reproduce can increase individual fitness and is a strong evolutionary factor shaping animal populations. However, few studies have investigated the inter... (Source: Frontiers in Zoology)

Cryptic diversity in smooth-shelled mussels on Southern Ocean islands: connectivity, hybridisation and a marine invasion
Large numbers of endemic species inhabit subantarctic continental coasts and islands that are characterised by highly variable environmental conditions. Southern hemisphere populations of taxa that are morphol... (Source: Frontiers in Zoology)

The “amphi”-brains of amphipods: new insights from the neuroanatomy of Parhyale hawaiensis (Dana, 1853)
Over the last years, the amphipod crustacean Parhyale hawaiensis has developed into an attractive marine animal model for evolutionary developmental studies that offers several advantages over existing experiment... (Source: Frontiers in Zoology)

Small-scale phenotypic differentiation along complex stream gradients in a non-native amphipod
Selective landscapes in rivers are made up by an array of selective forces that vary from source to downstream regions or between seasons, and local/temporal variation in fitness maxima can result in gradual s... (Source: Frontiers in Zoology)

Goats distinguish between positive and negative emotion-linked vocalisations
Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination within a group. Despite its evolutionary importance, social communication of emotions in ... (Source: Frontiers in Zoology)

A nemertean excitatory peptide/CCHamide regulates ciliary swimming in the larvae of Lineus longissimus
The trochozoan excitatory peptide (EP) and its ortholog, the arthropod CCHamide, are neuropeptides that are only investigated in very few animal species. Previous studies on different trochozoan species focuse... (Source: Frontiers in Zoology)

Repeatability of signalling traits in the avian dawn chorus
Birdsong, a key model in animal communication studies, has been the focus of intensive research. Song traits are commonly considered to reflect differences in individual or territory quality. Yet, few studies ... (Source: Frontiers in Zoology)

Among-population divergence in personality is linked to altitude in plateau pikas (Ochotona curzoniae)
Animals inhabiting high altitudes consistently show slow life-histories. The pace-of-life syndrome (POLS) hypothesis posits behavioural, physiological and/or morphological traits that mediate the trade-off bet... (Source: Frontiers in Zoology)

Under pressure: force resistance measurements in box mites (Actinotrichida, Oribatida)
Mechanical defenses are very common and diverse in prey species, for example in oribatid mites. Here, the probably most complex form of morphological defense is known as ptychoidy, that enables the animals to ... (Source: Frontiers in Zoology)
