Fig. 3 in Gallancyra gen. nov. (Phthiraptera: Ischnocera), with an overview of the geographical distribution of chewing lice parasitizing chicken
Fig. 3. Geographical distribution of four species of menoponid chewing lice parasitizing wild and domestic chicken (Gallus spp.). Each circle is divided into four sectors, representing the four louse species: upper left = Menacanthus cornutus (Schömmer, 1913); upper right = Menacanthus stramineus (Nitzsch, 1818); lower left = Menacanthus pallidulus (Neumann, 1912); lower right = Menopon gallinae (Linnaeus, 1758). Black sectors indicate that this louse species is known from this country, whereas hollow sectors indicate that we have found no published records of this species in this country. The presence of the four species of chewing lice in a country is based on the reports summarized in Table 1. Note that the menoponid species Amyrsidea powelli (Bedford, 1920) appears to be established on chicken in Nigeria (Fabiyi 1986, 1996), and that Menacanthus longiscleritus Naz & Rizvi, 2016, has been described from chicken in Pakistan. These are not shown on the map.

Fig. 1. Geographical distribution of three species of ischnoceran chewing lice parasitizing wild and domestic chicken (Gallus spp). Each circle is divided into three sectors, representing the three louse species: upper left = Goniodes gigas (Taschenberg, 1879); upper right = Goniodes dissimilis Denny, 1842; lower = Goniocotes gallinae (De Geer, 1778). Black sectors indicate that this louse species is known from this country, whereas hollow sectors indicate that we have found no published records of this species in this country. Presence of the three species of chewing lice in a country is based on the reports summarized in Table 1.

Fig. 4. Geographical distribution of the known records of Gallancyra dentata (Sugimoto, 1934), based on the reports cited in Table 1. Black circles indicate countries where G. dentata has been reported at in at least one survey, including the present report. Hollow circles indicate countries for which surveys of domestic chicken have been published, but G. dentata has not been found. In addition to the areas indicated on the map, Emerson (1956) reported G. dentata from "various islands in the Central Pacific Area", but gave no detail.
Fig. 14 in Gallancyra gen. nov. (Phthiraptera: Ischnocera), with an overview of the geographical distribution of chewing lice parasitizing chicken
Fig. 14. Gallancyra dentata (Sugimoto, 1934) gen. et comb. nov. ex Gallus gallus (Linnaeus, 1758) (NHMUK010682393). Male legs I–III, dorsal and ventral views. Legs II and III distorted in all examined males, and here illustrated approximately; note that marginal and near-marginal setae (marked with small black circles) are illustrated on both dorsal and ventral side, as their exact placement is difficult to establish due to the distortion of the legs. Some setae on tibiae II–III appear hyaline in examined specimens, and have here been illustrated as hollow.

Leaf vibrations produced by chewing provide a consistent acoustic target for plant recognition of herbivores
<p>Plant defenses that respond to the threat of herbivory require accurate sensing of the presence of herbivores. Herbivory cues include mechanical damage, elicitors from insect saliva or eggs, and airborne volatiles emitted by wounded plants. Plants can also respond to the leaf vibrations produced by chewing herbivores. However, previous studies of the influence of feeding vibrations on plant defenses have been limited to single species pairs. In this study we test the hypothesis that chewing vibrations differ among herbivore species, both in their acoustic features and in their effect on plant defense responses. We first compare the acoustic traits of larval feeding vibrations in ten species from six families of Lepidoptera and one family of Hymenoptera. We then test responses of <i>A. thaliana</i> plants to variation among feeding vibrations of different individuals of one species, and to feeding vibrations of two species, including a pierid butterfly and a noctuid moth. All feeding vibrations consisted of repetitive pulses of vibration associated with leaf tissue removal, although chewing rates varied between species and between large and small individuals within species. The frequency spectra of the vibrations generated by leaf feeding were similar across all ten species. Induced defenses of <i>A. thaliana</i> did not differ when plants were played vibrations from different individuals, or vibrations of two species of herbivores with different chewing rates, when amplitude was held constant. These results suggest that feeding vibrations provide a consistent set of cues for plant recognition of herbivores.</p>
Data from: Chewing on the trees: constraints and adaptation in the evolution of the primate mandible
Chewing on different food types is a demanding biological function. The classic assumption in studying the shape of feeding apparatuses is that animals are what they eat, meaning that adaptation to different food items accounts for most of their interspecific variation. Yet, a growing body of evidence points against this concept. We use the primate mandible as a model structure to investigate the complex interplay between shape, size, diet and phylogeny. We find a weak but significant impact of diet on mandible shape variation in primates as a whole but not in anthropoids and catarrhines as tested in isolation. These clades mainly exhibit allometric shape changes which are unrelated to diet. Diet is an important factor in the diversification of strepsirrhines and platyrrhines and a phylogenetic signal is detected in all primate clades. Peaks in morphological disparity occur during the Oligocene (between 37 and 25 Ma) supporting the notion that an adaptive radiation characterized the evolution of South American monkeys. In all primate clades, the evolution of mandible size is faster than its shape pointing to a strong effect of allometry on ecomorphological diversification in this group.
