Nevertheless, its reproductive biology has been poorly reported to date. We studied the gametogenic cycle of an intertidal rocky shore population from northern Patagonia (Argentina), in order to investigate the relation between gonadal changes and seasonal environmental variables. Mature individuals were taken monthly during an annual reproductive season and processed by standard histology procedures (haematoxylin and eosin). Adults of T. geversianus registered different gonadal maturation stages along the year, showing a marked seasonal variation without a resting period. The highest gamete evacuation season in both sexes was registered when the environmental stress was minimum (winter), while a greater number of individuals with gonads in proliferation and growth were predominant during maximum environmental stress (summer). The reproduction pattern presented an extended period of evacuation and a short phase of non-evacuation, associated to drastic seasonal environmental changes in the intertidal zone of Atlantic Patagonia. This information is useful to protect the resource and assure the sustainability of intertidal populations.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"66 1","pages":"135 - 146"},"PeriodicalIF":0.8,"publicationDate":"2022-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44123380","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}

Haemolymph, exoskeleton, muscle, gonads and hepatopancreas from both sexes, as well as egg parcels from berried females were collected within days of removing the animals from the ocean. The astaxanthin profile is, therefore, representative of spiny lobsters in the wild. Astaxanthin is significantly more in exoskeleton, ovaries and egg parcels, and is influenced by the ovarian cycle in females: it accumulated in growing oocytes and remained in the extruded eggs ostensibly for protection as antioxidant. Radioactive inulin was used to determine total haemolymph volume of a spiny lobster and the gravimetric contribution of body organs and various tissues to the total weight of these animals were measured: muscle tissue constitutes 33% of the total wet weight of J. lalandii, while haemolymph (22%) and exoskeleton (20%) are other major contributors. For maximal harvesting of astaxanthin from carcases, it would thus, be best to focus only on the exoskeleton with an emphasis on the carapace, which can be easily removed.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"66 1","pages":"120 - 134"},"PeriodicalIF":0.8,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45622999","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}

Blood phenylalanine levels were analyzed using the high-performance liquid chromatography method.Results: Mild HPA-not-requiring-treatment (NT) was found in 50.9% of the patients, and a classical phenylketonuria (PKU) phenotype was found in 25.9%. Forty-seven types of variants were identified. The predominant variants were p.Ala403Val (9.9%), p.Ala300Ser (9.4%), and c.1066-11G>A (splicing) (9.4%). Missense mutations accounted for 68% of mutations and attenuated the clinical impact; splice variations were found in 14.8% of cases with severe features. The p.Thr380Met allele was specific to the mild HPA-NT group. The c.1066-11G>A (splicing) allele was associated with classical PKU, whereas the p.Arg408Trp allele was linked to severe symptoms. Three variations of unknown clinical significance were discovered: c.706+4A>T (splicing), c.843-5T>C (splicing), and p.Thr323=. Of these variants, the patient who was homozygous for the c.843-5T>C (splicing) allele related to the classical PKU phenotype. 70% of the patients who underwent tetrahydrobiopterin (BH4) test were responsive. Phenotypes that responded to BH4 treatment were mostly mild phenotypes.Conclusions: The PAH genotype is the main factor that determines the phenotype of PKU. Establishing the relationship between the identified genetic mutations and phenotypic characteristics will provide very important data for each patient in terms of the specific management style.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"53 1","pages":"639-647"},"PeriodicalIF":0.0,"publicationDate":"2022-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81553808","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}

Spermatozoa are elongated aflagellate cells of clavate shape.

The basal part of the tube contains a cluster of vesicles. The slender posterior part of the spermatozoa includes an axial nucleus without a nuclear envelope surrounded by a halo and multivesicular complex composed of cisternae arranged into three layers. Spermatozoa of G. alpestris are nearly identical in size, proportion and internal structure to those of other gordiid spermatozoa. This uniformity makes spermatozoa useless for taxon descriptions and differentiation of Gordiida. The basic pattern of spermatozoon structure in Gordiida is not fully understood and requires more detailed studies. Controversies include absence or presence of the nuclear envelope and mitochondria, together with interpretation of the halo surrounding nuclei and membranous compartments of the acrosomal and multivesicular complexes. Detailed study of sperm development together with cytochemical analysis of components such as mitochondria, acrosome, perforatorium and halo might be helpful for understanding sperm relationships of Gordiida and Nematoda.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"66 1","pages":"88 - 96"},"PeriodicalIF":0.8,"publicationDate":"2022-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41921091","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}

Five cohorts of propagules (embryos/larvae) were exposed to temperature treatments (28–29, 24–25 and 20–22°C) in standardized culture settings. Under the coldest temperatures (typical of offshore upwelling areas), development mirrored that obtained under warmer temperatures until the early auricularia stage, where development was arrested for ~5 months in a manner consistent with quiescence. When temperature was increased again, larvae quickly resumed development and settled; no lasting negative impact was noted. The findings suggest that the larvae can use a form of dormancy to withstand suboptimal oceanic conditions for indefinite periods of time until successful delivery to appropriate inshore locations, the habitat were I. fuscus is exclusively found.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"66 1","pages":"79 - 87"},"PeriodicalIF":0.8,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41506600","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}

Previous research indicates that degradation of MF in crustaceans is similar to JH III degradation, and involves specific carboxylesterases. Juvenile hormone esterase hydrolase (JHEH) is another important enzyme responsible for JH inactivation in insects. In this study, the full-length cDNA of EsJHEH-like was identified and characterized in Eriocheir sinensis. Sequence analysis showed that EsJHEH-like belongs to the microsomal epoxide hydrolase (mEH) family containing several typical motifs. Quantitative PCR results showed that EsJHEH-like was expressed primarily in the hepatopancreas. During ovarian development, EsJHEH-like mRNA expression in the hepatopancreas was elevated specifically in the early vitellogenic stage, prior to the remarkable rise in haemolymph MF titre reported in previous studies, but no significant changes in the ovary. In addition, EsJHEH-like expression in the hepatopancreas was notably greater than in the ovary at each stage except for previtellogenic oocytes. Furthermore, EsJHEH-like expression in the hepatopancreas was significantly induced in vitro and in vivo, but not in the ovary. Taken together, these results suggest that EsJHEH-like may potentially serve as an MF hydrolase involved in the degradation of MF.","PeriodicalId":14482,"journal":{"name":"Invertebrate Reproduction & Development","volume":"66 1","pages":"23 - 32"},"PeriodicalIF":0.8,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49149845","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}
