Across the Metazoa, the emergence of new ecological interactions has been enabled by the
repeated evolution of exocrine glands. Specialized glands have arisen recurrently and with …

Alkaloids in the skin glands of poison frogs serve as a chemical defense against predation,
and almost all of these alkaloids appear to be sequestered from dietary arthropods. Certain …

Oribatid mites, also called beetle or moss mites, include more than 10,000 named species
representing 172 families worldwide. This book provides an identification key to the 96 …

Arachnida represent a hyperdiverse group of terrestrial arthropods. Although arachnids are
mostly predators, they often fall prey to other predators. Here, the diversity of enemies and …

A reliable phylogeny is crucial for understanding the evolution and radiation of animal taxa.
Phylogenies based on morphological data may be misleading due to frequent convergent …

Poison frogs are chemically defended from predators by diverse alkaloids, almost all of
which are sequestered unchanged from alkaloid-containing arthropods in the frog diet …

The multicomponent oil gland secretion of Collohmannia gigantea, a middle-derivative
mixonomatan oribatid mite, is demonstrated to possess alarm pheromonal and allomonal …

Oribatid mites are diverse and abundant terrestrial soil arthropods that are involved in
decomposition of organic matter and nutrient cycling. As indicated by fossils starting from the …

The presence of dermal glands is a synapomorphy in the freshwater mites—the large
branch of the hyporder Parasitengonina. Dermal glands of the mite Limnesia maculata (OF …

Opisthonotal glands of sarcoptiform mites secrete a variety of compounds known to have
defensive and pheromonal functions. We studied the gland chemistry of cultured individuals …
