Our study was carried out with the help of gross, scanning electron microscopy (SEM), and morphometric analysis. The lower median papillary teeth-like region corresponded to the lower papillary region in terms of food particle capture. The serrated gnathotheca surface exhibited transverse, wedge-like, cap-like, and serrated border-like processes. The lower mandibular space had four spaces: the rostral smooth, the middle folded, the long sublingual, and the caudal sublaryngeal space. The palate showed two major regions, the rostral long beak (beak nail, middle part, and the caudal papillary part) and the connecting region. The choana consists of the rostral narrow part, which has rostral non-papillated and caudal papillated parts, and the caudal papillated wide part, which has three papillary rows. The infundibular plate had numerous small papillae and sphenopterygoid salivary gland openings. Functionally, the beak plays an important role in the sieving filter feeding mechanism, and the palate is involved in the fixation of the captured food particles inside the oral cavity. Consequently, beak and palate structures exhibit anatomical adaptations for efficiently filtering feeding mechanisms.</p></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"311 ","pages":"Pages 1-15"},"PeriodicalIF":1.4,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141133878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, intraspecific variation assessment is often hindered by inaccurate morphological results from traditional methods or high-cost genetic analyses. Geometric morphometrics is a promising technique for quantifying and visualising intraspecific diversity. We used landmark-based geometric morphometrics to investigate forewing shape variation and microtaxonomy of populations of <em>Apis florea</em> Fabricius 1787 (Apidae: Apini), which originated from some parts of Asia and Africa based on the 19 landmarks plotted at the venation intersections of forewings. We collected samples of 162 colonies from 36 different localities. On average, 13 workers per colony were analysed (1851 bees in total). Distinct spatial structures and significant differences in wing shape between the studied populations were revealed using canonical variate analysis, and no considerable overlap was detected between the colonies belonging to the western and eastern populations. The populations at higher latitudes showed significantly larger centroid sizes than those at lower latitudes, and a clinal variation in forewing size was confirmed. Significant distance-decay relationships between the studied populations were observed so that the populations located at the maximum geographical distance showed the most significant distance from each other and vice versa. Wing geometric morphometrics was an accurate tool for the reliable estimation of the population structure of the red dwarf honeybees. It is essential to increase the reliability of these variations by combining the results with further molecular data.</p></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"310 ","pages":"Pages 73-80"},"PeriodicalIF":1.4,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140913991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the taxonomic value and determine the patterns of variability of this character, alizarin-stained skin samples of 19 diadromous and freshwater sculpins from Eurasia and one ancient North American species, <em>Leptocottus armatus</em>, were examined for the morphology of prickles. Three morphological types of prickles were ascertained. The largest prickles with a wide basal plate having an uneven anterior edge and a short, strong spine should be considered as the ancestral state. On a series of prickles examined a successive process of reduction was revealed from the ancestral type to the prickles that represent a thin, elongated, fusiform spine extending from a barely visible rounded basal plate with a smooth anterior edge, usually specific for younger freshwater species. The types of skin armament are not strictly consistent with the current concepts on the phylogeny of the studied freshwater Cottidae in view of the phenotypic parallelisms in this group. It is tentatively indicated insignificant intraspecific variation of the prickles shape in <em>Mesocottus haitej</em>, <em>Cottus amblystomopsis</em>, <em>C. czerskii</em>, and <em>C. volki</em>. Identification of most species studied using a single prickle is quite a challenge, although some species are easily identified this way. The species-specificity of prickles is shown to be the greatest in deeply divergent lineages, providing the opportunity to use these structures for diagnosing species and revealing hidden species richness.

This evolutionary journey is characterised by the emergence of the head compartment during the Cambrian radiation, the evolution of jaws during the Silurian, and the subsequent diversification of vertebrate groups. The cranium, consisting of the neurocranium, dermatocranium, and viscerocranium, plays a central role in craniofacial support. Research on the development of the cranium has been carried out in several vertebrate species, providing valuable insights into their unique patterns of cartilage development. While most vertebrates show typical sequences of chondrocranial development, anurans divert from these patterns. Our study focused on the chondrocranial development of Congo dwarf frog <em>Hymenochirus boettgeri</em> (Anura: Pipidae) tadpoles, providing a detailed sequential analysis from mesenchymal elements to the premetamorphic chondrocranium. The chondrocranium of these tadpoles showed several reductions as a consequence of their miniaturization and their unique suction feeding lifestyle. We found a mosaic-like development of anuran mandibular and hyoid arches, and we also discussed the intricate patterns of suprarostral cartilage development and deviations in branchial basket development compared to other anuran species. Our study also contrasts anuran neurocranial development with that of other osteichthyan species, highlighting unique features such as the similar direction of development of anterior and posterior neurocranial components. Overall, our research contributes to our understanding of chondrocranial development in anurans, highlighting both conserved and unique features in <em>H. boettgeri</em> tadpoles. Our findings enrich our knowledge of vertebrate cranial development and provide insights into the evolutionary history of anuran chondrocranial features.</p></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"310 ","pages":"Pages 53-66"},"PeriodicalIF":1.4,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0044523124000299/pdfft?md5=e92d28f7325912006035467afd5181a0&pid=1-s2.0-S0044523124000299-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140772547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
