Among the three populations, fish samples from Malimono have the highest cumulative variation of 63.07 % followed by San Francisco and Surigao City (60.85 % and 55.51 %). The high percentage of FA among the three populations (57.66 % in Malimono; 54.43 % in San Francisco; and 49.78 % in Surigao City) also suggests that individuals had deformities particularly, especially in the fins and head region of the fish. The LWR of the fish samples (b = 2.6398 in Malimono; b = 2.7541 in San Francisco; and b = 2.8377 in Surigao City) indicates a negative allometric growth pattern, suggesting that the fish samples do not grow symmetrically or become thinner with increasing length. The results of FA and LWR analyses suggest morphological abnormalities in the fish samples that may be attributed to the different environmental stressors in the area. Studies on sex differences, water quality and fish ecology are suggested to better understand the current status of fish in the area.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67088590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their activity period and dark habitats render visual cues ineffective and they rely on non-visual sensory perception. There is agreement among researchers that the whip spiders invest in olfactory and tactile senses imparted by sensory structures concentrated on the tarsal segment of the first pair of long, well-articulated non-ambulatory legs that are constantly moved in all directions to sample the environment for detecting location of prey, as also for navigating. This is the first attempt to elucidate the sensory structures present on the antenniform legs of the whip spider, Phrynichus phipsoni (Pocock, 1894), collected from the state of Goa, India; using scanning electron micro[1]scope, and paves way for further research on sensory biology of this cryptic arachnid order. The examined specimen generally conforms to the diversity and morphology of sensory assemblage on the antenniform legs reported in other amblypygi species. Sensory structures elucidated include terminal trident tarsal claws, tarsal organ, bristles, porous sensilla, club sensilla, rod sensilla, slit sensilla, trichobothria, plate organ, pit organ and foliate leaf like hairs.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134980418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that most species of the genus Loxoconcha consist of four adductor scars to arrange in a curved sub-vertical row and concave anteriorly, except L. pulchra carrying five, in which the top one is divided into two. The frontal scars with C-shape, opening anteriorly are presented in most of Loxoconcha species, however, the frontal scar with bean-shape or oval-shape is discovered in five species of L. japonica group. Most of L. kosugii bear the frontal scar with C-shape, but the frontal scar with Y-shape is found in several individuals. This phenemenon shows the close phylogeny between the genus Loxoconcha and Palmoconcha. About the genus Xestoleberis, chaetotaxy of setae on most appendages is a typical character of this genus, except for setae of exopodite on the maxillula. The published fossil records and the tendencies of change in the number of setae on the maxillula and mandible among three phylogenetic groups suggest that Group A or B is an ancestor of the genus Xestoleberis, and Group C is a derived group.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67088324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subcutaneous migration of the parasite Dirofilaria repens Railliet & Henry, 1911 may cause local swelling with variable localisation. In humans, this parasite can cause damage to the lungs, male genitalia and eyes. The range of D. repens is constantly expanding into new areas and, considering the zoonotic potential of this parasite, it is important to extend the existing data on the morphology of D. repens. The present study provides a morphometric description of D. repens nematodes obtained from subcutaneous tissues of dogs in Ukraine. The aim of this study was to highlight the key features for the identification of parasites of this species. For males, 27 morphometric characteristics were identified, characterising the overall size of the body and the oesophagus, the thickness of the cuticle in the region of the mouth opening, the localisation of the nerve ring and the cloaca, the morphological structure and metric parameters of the spicules, and the length of the tail. For females, 18 morphometric traits were identified that, in addition to common parameters, characterize cuticle thickness in the region of the vulva, localisation of the vulva and anus, body width in the regions of the anus and vulva, and tail length. This report adds to the existing data on the morphological and metric characteristics of D. repens nematodes.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67089154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meiobenthos was studied in three habitats: Exposed Black Sea upper infralittoral rock with Corallinales turf (MB142), Mytilid dominated exposed Black Sea upper infralittoral rock with foliose algae (no Fucales) (MB143) and Black Sea infralittoral sand and muddy sand without macroalgae (MB542). A total of 10 higher meiobenthos taxa were recorded in the different habitats: 5 permanent groups (Platyhelminthes, Nematoda, Harpacticoida (Copepoda), Ostracoda, Halacaridae) and 5 temporary groups (Oligochaeta, Polychaeta, Bivalvia, Gastropoda, Cyrripedia). The preliminary study of meiobenthos in the habitats of the Snake Island MPA showed that habitat MB143 was more favourable for meiobenthos, with the highest mean density and biomass (190655 ± 23004 ind.-m-2 and 3170.90 ± 412.15 mg-m-2, respectively). The comparative nMDS and cluster analyses based on the density of meiobenthos taxa in the Snake Island MPA showed that the meiofauna of both MB142 and MB143 differed significantly from the MB542 habitat, with Bivalvia and Ostracoda making the largest percentage contribution to these differences. The meiobenthos assemblages in the different habitats of the Snake Island MPA were similar to the other regions of the Black Sea with some unique features (e.g. relatively lower total meiobenthos density, high percentage of ostracodes on the algal substrate, etc.). Further studies on the characteristics of meiobenthos taxa assemblages in other Black Sea MPAs could lead to the estimation of meiobenthos assemblage patterns and their possible use in biomonitoring.","PeriodicalId":36290,"journal":{"name":"Zoodiversity","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134980895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
