The intestine of goldfish, like that of all vertebrates, plays an important role in the immunology of the animal. The gut-associated lymphoid tissue GALT is an immune component containing several specific cells such as lymphocytes, macrophages and mast cells. In addition, the presence of goblet cells in the intestinal epithelium strengthens the defence system, secreting many cytokines and chemokines and displaying antibacterial properties. Our results show mast cells labelled with antibodies that are highly conserved between fish and mammals, demonstrating an active role of these cells in the immune response.","PeriodicalId":50945,"journal":{"name":"Acta Zoologica","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50118091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present autoradiographic and immunohistochemical study describes tail regeneration and formation of the axial skeleton in early regenerating tails of the Jamaican red-tailed gecko, Sphaerodactylus argus. Cell proliferation, studied by tritiated thymidine, shows intense labelling mainly in forming scales and differentiating cartilaginous, muscle and ependymal cells of the regenerating spinal cord, while the labelling is more diffuse in the apical blastema and proximal connective tissues. The slow apical proliferation maintains the tail front growing while in more proximal regions, cells initiate differentiation, losing thymidine-labelling. Cell proliferation is maximal at the beginning of scales, muscles and cartilage formation. Scales are regenerated following migration into the dermis of tritiated thymidine-labelled keratinocytes to form epithelial pegs that later split and give rise new scales. Differentiation of new corneous layers begins underneath the external corneous epidermis, starting with a shedding layer followed by a beta-layer that accumulates corneous beta proteins. Intense proliferation of apical myoblasts gives rise to long myotubes and segmented muscles. The vertebral column is substituted with a cartilaginous tube made of turgid chondrocytes accumulating chondroitin sulphate proteoglycan and elastin. Therefore, the regenerated tail remains flexible and capable of curling to maintain efficient the climbing ability in these geckos.","PeriodicalId":50945,"journal":{"name":"Acta Zoologica","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50150648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all, we photographed 174 individuals on the right side of the body and 17 landmarks were digitized on each image. To study the effects of allometry on the shape, we performed regression analysis and, to study shape modulation at different collection points and sub-basins, the canonical variation analyses. We found differences in shape between collection points and sub-basins associated with relative body height and sub-orbital plate recoil, in addition to a significant influence of size on specimen shape (allometry) associated with the ventral skull, orbits and sub-orbital plate. We do not envision differences in body shape between males and females.

Acta Zoologica (Stockolm). Tail regeneration in lizards occurs after an immune-privileged blastema and is formed where various immunosuppressive cells and biomolecules keep inflammation low. Molecules that limit inflammation may include glutathione and glutathione S-transferase (GST). These molecules reduce reactive oxidative species (ROS) and detoxify extraneous molecules. In the present study, the presence of GST has been analysed in the early phases of tail regeneration in the lizard Podarcis muralis. Using a rabbit polyclonal antibody directed against epitopes present in GST of P. muralis, a light and electron microscopy immunohistochemical and Western blotting study has been done. The study detected proteins of 25 and 32 kDa in pale-medium electron-dense and large granules present in promyelocytes and myelocytes of likely basophilic or eosinophilic fate that is present in the bone marrow of tail vertebrae. These cells are still proliferating and give rise to basophilic or eosinophilic granulocytes that also migrate into the regenerating tail. The enzyme stored in granules of promyelocytes and myelocytes is also localized in the cytoplasm of granulocytes present in the regenerating blastema-cone, basophilic or/and eosinophilic. It is suggested that these granulocytes in the blastema reduce ROS and detoxify potentially inflammatory metabolites, contributing with other molecules to limit inflammation and favour regeneration.","PeriodicalId":50945,"journal":{"name":"Acta Zoologica","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50144986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, species that present commercial interest may have their population structure and spatial distribution affected by human activities, such as crab capture. Therefore, monitoring populations over time is essential. We investigated the population biology, size-weight relationship, condition factor and spatial distribution of Ucides cordatus in a mangrove ecosystem from southern Brazil, providing information for population status assessment. Males and females differed in abundance and frequency, body size, size-weight relationship and condition factor. Nonetheless, they presented the same spatial distribution pattern. Abundance, sex ratio and body size also revealed a possible influence of anthropised areas in the configuration and distribution of the species. Our results indicate a possible increase in the exploitation of the species, mainly due to the decrease of the largest male size classes’ frequency. Interspecific competition seems to be a possible biotic factor influencing its condition factor. The spatial species distribution highlighted the importance of sites with less anthropogenic influence for the maintenance of the species that can be considered as key areas for the conservation of the U. cordatus in Babitonga Bay.","PeriodicalId":50945,"journal":{"name":"Acta Zoologica","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50118776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the obtained results, sagitta morphology could be considered as diagnostic characters distinguishing the genera Alticus, Antennablennius, Istiblennius, Omobranchus and Parablennius showing differences related to general shape, that is, elliptic/oval to triangular; shape of antirostrum and its degree of development; the degrees of convexity of ventral and dorsal margins, and shape of ostium. The common/general otolith characters shared in the all studied combtooth blennies, is the heterosulcoid condition, which is a shared character with Perciformes and Gobiiformes.

Although the maximum water temperature was related to the recruitment, it can be physiologically risky for the remaining macroinvertebrate community. The relationship between abundance and narrow pH variations indicates a condition of unstable equilibrium given the environmental deterioration by deforestation. Sex ratio was predominantly male biased during copulatory activity, and sexually dimorphic body size distributions supported the hypothesis of greater natural selection in females and sexual selection in males. The period of ovigerous females was comparatively restricted, late and consistent with an efficient ecophysiological strategy of reproductive investment.

Significant differences were also observed with respect to the intensity of black pigmentation on larval body as well as adult eye and forewing colour patterns. Besides external phenotypic traits, the length of genital organs like aedeagus and valva in males, and bursa copulatrix and bursa seminalis in females also differed significantly amongst populations. The dendrogram based on selected traits showed clear cut differentiation of studied populations into two major groups, one including all the South Zone populations and the other having populations from North and Central Zones.
