Pigmentation disorders in three specimens of spiny dogfish, Squalus acanthias Linnaeus, 1758, from the Gulf of Venice, northern Adriatic Sea

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study reports three cases of pigmentation disorders in Squalus acanthias from the Gulf of Venice. Two specimens exhibited spotless phenotypes, whereas one exhibited hypermelanism. Morphological assessments were conducted for two individuals, alongside genetic analysis of mitochondrial genes to determine phylogeographic relationships. Both

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

New evidence on the formation conditions of the Libyan Desert Glass (Western Egypt): Clues from a dendritic zircon inclusion

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Libyan Desert Glass (LDG) is an ~29 million years old, silica‐rich glass found in Western Egypt. Whether this glass formed in an impact cratering context associated with the hypervelocity collision of a cometary/asteroidal body or radiative heating during an airburst is debated. Determination of the formation temperatures and pressures of rare

Faunistic inventory of the genus Culicoides (Diptera: Ceratopogonidae) in Mauritius Island, Indian Ocean: Diversity and spatial distribution of species of veterinary interest Inventaire faunistique du genre Culicoides (Diptera: Ceratopogonidae) sur l'île Maurice dans l'océan Indien: diversité et répartition spatiale des espèces présentant un intérêt vétérinaire

open access: yesMedical and Veterinary Entomology, EarlyView.
Four Afrotropical Culicoides species are recorded in Mauritius with suspected or historically involvement in BTV and EHDV transmission. All species were distributed all over the island. While intra‐specific morphological variations were detected, genetic analyses did not reveal any cryptic diversity. Abstract Viruses transmitted by biting midge species

Hybridity of mainly asexually propagating duckweeds in genus Lemna – dead end or breakthrough?

open access: yesNew Phytologist, EarlyView.
Summary The cosmopolitan, mainly vegetatively propagating, organ‐reduced monocotyledonous aquatic duckweeds are the smallest and fastest growing angiosperms, distributed world‐wide and flower rarely in nature. Recently, we reported intra‐ and interspecific hybrids and ploidy variants in the genus Lemna.
