The latter could represent a strong ecological pressure on the species, giving rise to phenotypic variation mainly in those functional traits that are determining for the species. In this study, we used a broad geographic sampling of <em>Lu. cruciata</em> and geometric morphometric techniques to assess variation in head shape in populations from two environmentally heterogeneous biogeographic provinces, Veracruz and the Yucatán Peninsula. We also tested whether morphological variation could be related to the climatic conditions across the two biogeographical provinces. We found that head shape revealed more differences among populations within provinces than between them. Such morphological head shape variation was not associated with bioclimatic or geographical variables in either province. This pattern of morphological variation in head shape is congruent with previous evidence on the wing shape of <em>Lu. cruciata</em> populations. Further studies of these and other populations using genetic markers are clearly needed to allow a more precise estimate of variation or differentiation in this sand fly vector.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"313 ","pages":"Pages 208-216"},"PeriodicalIF":1.2,"publicationDate":"2024-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142531852","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}

In our studies of Lower Diptera (Nematocera) (<em>Lutzomyia longipalpis</em> Lutz &amp; Neiva, 1912, <em>Aedes aegypti</em> Linnaeus, 1762, and <em>Culex quinquefasciatus</em> Say, 1823), we observed differences in midgut morphology between males and females.

Interestingly, in the non-hematophagous insect <em>Clogmia albipunctata</em> Williston, 1893 (Diptera: Psychodidae) both males and females possess a tubular and narrow midgut. Our showed that the observed differences are related to hematophagy, where all hematophagous females have a midgut with prominent posterior dilation, while females from non-hematophagous species have a narrowed midgut.

Among phoronids, <em>Phoronis embryolabi</em> is distinguished by a most unusual type of development: larval viviparity. In the present work, we characterize spermatogenesis in this species using transmission and scanning electron microscopy. The results indicate that the development of male gametes occurs within the vasoperitoneal tissue. Early spermatocytes have a well-developed secretory apparatus comprising a Golgi body and endoplasmic reticulum. The Golgi body, which is retained until the late spermatid stage, produces acrosome material, thick glycocalyx, and membrane vesicles that are presumably necessary for the elongation of initially small cells into filiform mature spermatozoa. The germ cells retain their connections with each other until the late spermatid stage. The mature sperm of <em>P. embryolabi</em> can be regarded as an introsperm, which is characteristic of species with internal fertilization. The structure of mature sperm differs from that of other phoronid species, whose sperm can be described in terms of the form and location of organelles. <em>P. embryolabi</em> sperm differs in the location of the acrosome, in the presence of a collar around the base of the flagellum, and due to the close attachment of the flagellum to the non-flagellar part of the cell. Due to this attachment, a mature <em>P. embryolabi</em> spermatozoon is probably able become an undulating cell capable of movement in the densely packed inner space of an animal. The filiform shape of the mature sperm is likely correlated with the specificity of the <em>P. embryolabi</em> reproductive strategy, i.e. viviparity of larvae, when thousands of embryos, larvae, germ cells, and cells of vasoperitoneal tissue occupy the body cavity; thus, the spermatozoon has to squeeze in narrow spaces.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"313 ","pages":"Pages 102-114"},"PeriodicalIF":1.2,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328273","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}
