“…While M. mungo is similarly insectivorous, feeding primarily on millipedes with beetles, ants, crickets, termites, and earwigs also comprising an important part of its diet, it also exploits vertebrate prey consisting of frogs, snakes, toads, and murid rodents; however, these prey species have been observed to make up a relatively small proportion of their diet (Rood, 1975). H. javanicus consumes a wide variety of both vertebrates and invertebrates (Subrata, Siregar, André, & Michaux, 2021). While its diet is primarily comprised of the greater bandicoot rat ( Bandicota indica ) and the domestic chicken ( Gallus gallus ), fecal samples have revealed the presence of various mammals, birds, amphibians, snakes, fish, and many insects as well (Subrata et al, 2021).…”

Carnivorans represent extreme ecomorphological diversity, encompassing remarkable variation in form, habitat, and diet. The relationship between the masticatory musculature and dietary ecology has been explored in a number of carnivoran lineages, including felids and the superfamily Musteloidea. In this study, we present novel architectural data on two additional carnivoran families—Ursidae and Canidae—and supplement these previous studies with additional felid, musteloid, herpestid, hyaenid, and viverrid taxa (a total of 53 species across 10 families). Gross dissection data were collected following a standardized protocol—sharp dissection followed by chemical digestion. Summed jaw adductor forces were also transformed into bite force estimates (BF) using osteologically calculated leverages. All data were linearized, log‐transformed, and size‐adjusted using two proxies for each taxon—body mass (BM) and cranial geometric mean—to assess relative scaling trends. These architectural data were then analyzed in the context of dietary ecology to examine the impact of dietary size (DS) and dietary mechanical properties (DMP). Muscle mass, physiological cross‐sectional area, and BF scaled with isometry or positive allometry in all cases, whereas fascicle lengths (FLs) scaled with isometry or negative allometry. With respect to diet, BM‐adjusted FLs were strongly correlated with DS in musteloids, but not in any other lineage. The relationship between size‐adjusted BF and DMP was also significant within musteloids, and across the sample as a whole, but not within other individual lineages. This interfamilial trend may reflect the increased morphological and dietary diversity of musteloids relative to other carnivoran groups.

“…The precise impact of exotic invasive mammals, particularly mongooses and feral cats, on columbids and other bird species of conservation interest in Guadeloupe clearly deserves further investigation. This could be achieved through studying diet composition of predators from faecal pellets and/or stomach contents, preferentially relying on modern molecular tools [125][126][127]. Such information could be particularly useful to contrast the impact of hunting pressure (see Carvalho et al [128]), which is limited to a restricted hunting season in Guadeloupe, to that of exotic invasive mammals that are supposedly active all year long.…”

Although forest-dependent, tropical island endemic birds are particularly at risk of extinction, they remain largely understudied. In this context, we assessed the spatial occupancy, local abundance, and diel activity in three forest columbid species of hunting interest, the Ruddy Quail-Dove (RQD), Geotrygon montana; the Bridled Quail-Dove (BQD), Geotrygon mystacea; and the Zenaida Dove (ZD), Zenaida aurita, in Guadeloupe (French West Indies), using 5 camera-traps over 14 days on 24 survey stations, resulting in 1680 trap days. The number of observed RQD was too small to allow for a statistical comparison between habitats. BQD were more frequently observed at camera-trap stations that were dominated by tropical rainforest than those that were dominated by flooded forest. Conversely, ZD were more frequently observed at stations that were dominated by flooded forest and dry forest than at those that were dominated by tropical rainforest. High temperatures negatively affected the abundance of BQD, while the abundance of ZD was significantly lower in tropical rainforests compared to dry and flooded forests and tended to increase with canopy openness. The three species were diurnal. BQD significantly positively co-occurred spatially and temporally with small Indian mongooses, Urva auropunctata, whereas the temporal and spatial distribution of ZD overlapped significantly with that of domestic dogs, Canis familiaris, and domestic cats, Felis catus. Our results provide firm evidence that RQD remains scarce and is largely outnumbered by BQD in Guadeloupe which is in contrast with has been reported for other Caribbean islands.

Grasshoppers are common pests, and their intestinal microbes have coevolved with them. These microorganisms have varied community structures, and they participate in the nutritional absorption and metabolism of grasshoppers. Here, we describe the gut microbiota diversity of four species of grasshoppers, Oxya chinensis, Pararcyptera microptera meridionalis, Gastrimargus marmoratus, and Calliptamus abbreviatus. We constructed a 16S rDNA gene library and analyzed the digestibility of cellulose and hemicellulose in grasshoppers using moss black phenol and anthrone colorimetry. The grasshopper with the highest microbial diversity in the gut among the four species was Oxya chinensis, and there were no significant differences in gut microbial diversity between the two geographic collections of Oxya chinensis. The most dominant phyla of the four grasshopper gut microorganisms were Proteobacteria, Bacteroidetes, and Firmicutes, and the most dominant genus was Enterobacter. The gut microbiota features of the four grasshoppers were correlated with their cellulose and hemicellulose digestibility. There was a significant positive correlation with cellulose digestibility for Pantoea. A significant negative correlation was found with cellulose digestibility for Acinetobacter, Enterococcus, Citrobacter, Serratia. A significant negative correlation was found with hemicellulose digestibility for Pantoea. This study contributes to the understanding of the structural composition of different species of grasshoppers gut microbiota, which may be useful for developing grasshopper digestive tracts as bioreactors for cellulose decomposition, improving the decomposition and utilization of agricultural straw, producing clean biomass energy, and processing biologically derived products.
