Foot-and-mouth disease (FMD) is a highly contagious disease affecting cloven-hoofed ungulates. This study aimed to enhance our understanding of the role of small ruminants and environmental contamination in the epidemiology and endemicity of FMD. A longitudinal study was conducted between March 2021 and October 2021 in northern Nigeria, where monthly samples were collected from five households, one livestock market and one transhumance location in two local government areas (LGA) identified as being at high risk of FMD.

Cameroon was the first African Torrent toad to be described, soon followed by Atelopus africanus Werner, 1898 from Bismarkburg in Togo. Shortly after, both species were considered conspecific and, currently, both fall under the name Werneria preussi following taxonomic revisions.

Molecular data have been suggesting the existence of a complex of cryptic species within the taxon Perinereis cultrifera , which has not been fully explored yet. In this study, we performed a morphological and molecular analysis (mtCOI-5P , 16S rRNA and 28SD2 rRNA ) of Perinereis specimens from intertidal marine and brackish European localities, mostly focusing on the Mediterranean Sea and the Canary Islands. Two major phylogenetic clades with at least 18 divergent (COI , 19.

The earliest named stromatolite Cryptozoon Hall, 1884 (Late Cambrian, ca. 490 Ma, eastern New York State), was recently re-interpreted as an interlayered microbial mat and non-spiculate (keratosan) sponge deposit. This "classic stromatolite" is prominent in a fundamental debate concerning the significance or even existence of non-spiculate sponges in carbonate rocks from the Neoproterozoic (Tonian) onwards.

Despite the current recognition of and as two separate valid species of China, neither species have been revised based on examination of their types and/or topotypical materials, nor have they genetically analyzed. In this study, examination of the holotype of showed that it has a serrated anterior edge of the pectoral spine, a slightly emarginate caudal fin, and longer maxillary barbels extending beyond the base of the pectoral spine, the characters shared with specimens currently identified as . Morphological comparisons and molecular analysis showed that specimens from mainland China, which are characterized by the three mentioned morphological features, represent a single species.
