The discovery and exploration of cryptic species have been profoundly expedited thanks to developments in molecular biology and phylogenetics. In this study, we apply a reverse taxonomy approach to the Brachionus calyciflorus species complex, a commonly studied freshwater monogonont rotifer. By combining phylogenetic, morphometric and morphological analyses, we confirm the existence of four cryptic species that have been recently suggested by a molecular study. Based on these results and according to an exhaustive review of the taxonomic literature, we name each of these four species and provide their taxonomic description alongside a diagnostic key.

Background And Aims: The cosmopolitan Botrychium lunaria group belong to the most species rich genus of the family Ophioglossaceae and was considered to consist of two species until molecular studies in North America and northern Europe led to the recognition of multiple new taxa. Recently, additional genetic lineages were found scattered in Europe, emphasizing our poor understanding of the global diversity of the B. lunaria group, while the processes involved in the diversification of the group remain unexplored.

Background matching and disruptive coloration are defense mechanisms of animals against visual predators. Disruptive coloration tends to evolve in microhabitats that are visually heterogeneous, while background matching is favored in microhabitats that are chromatically homogeneous. Controlling for the phylogeny, we explored the evolution of the coloration and the marking patterns in the sexual dichromatic and widely distributed neotropical grasshoppers of the genus Sphenarium.

The genus in the North Atlantic comprises of long lived deep-waters species that have been extensively fished upon, and many stocks are severely depleted across the Atlantic. This is particularly evident for the species . In recent papers, cryptic species have been indicated within this genus and molecular markers are therefore needed to provide identification for the species, including the cryptic species as a basis for advice regarding management and rebuilding of the stocks.

The advent of digital wildlife cameras has led to a dramatic increase in the use of camera traps for mammalian biodiversity surveys, ecological studies and occupancy analyses. For cryptic mammals such as mice and shrews, whose small sizes pose many challenges for unconstrained digital photography, use of camera traps remains relatively infrequent. Here we use a practical, low-cost small mammal camera platform (the "MouseCam") that is easy and inexpensive to fabricate and deploy and requires little maintenance beyond camera service.

A survey of the moss flora of the southernmost part of the Russian Primorsky Territory yielded several intriguing taxa, whose identity is assessed herein based on an integrative morpho-molecular approach. was previously known in inland Asia only from the Sino-Himalayan region and the new locality is distant from the earlier known ones to ca. 3000 km.
