Copepods, the most abundant individuals of mesozooplankton, play a pivotal role in marine food webs and carbon cycling. However, few studies have focused on their diversity environmental factors influencing it. The objective present study is to model alpha beta copepods across tropical subtropical ecoregions Atlantic Ocean using both taxonomic functional approaches. used dataset 226 copepod species collected by stratified plankton hauls (0-800 m depth) equatorial Atlantic, from oligotrophic...
Somatic cell nuclear transfer (SCNT) is a very promising cloning technique for reconstruction of endangered animals. The aim the present research to implement interspecific SCNT (iSCNT) sturgeon; one fish family bearing some most critically species. We transplanted single cells enzymatically isolated from dissociated fin-fragment Russian sturgeon (Acipenser gueldenstaedtii) into non-enucleated eggs sterlet ruthenus), two species different ploidy (4n and 2n, respectively). Up 6.7% underwent...
The fish body shape is a key factor that influences multiple traits such as swimming, foraging, mating, migrations, and predator avoidance. present study describes the morphological changes growth trajectories during transformation from 24 to 54 days post-hatching in golden grey mullet, Chelon auratus, using geometric morphometric analysis (GMA). results revealed decrease variability (i.e., disparity) with somatic growth. main affected head size, elongation, widening of body. Given this...
Conservation of chicken germplasm is crucial in supporting commercial breeds for sustainable egg and meat production preserving the genetic diversity indigenous future breeding. Cryopreservation fertilized eggs or embryos not feasible, owing to large yolk-laden structure eggs. Primordial germ cells (PGCs), embryonic precursors gametes, are best candidates cryobanking germplasm. Effective PGCs requires an optimal cryopreservation protocol. Cryomedia containing dimethyl sulfoxide (DMSO) DMSO...
Abstract Several steps of sturgeon somatic cell nuclear transfer (SCNT) have been recently established, but improvements are needed to make it a feasible tool preserve the natural populations this group endangered species. The donor position inside recipient egg seems be crucial for its reprogramming; therefore by injecting multiple cells instead single with manipulation, we increased potential embryo development. Using Russian Acipenser gueldenstaedtii as and sterlet ruthenus non-enucleated...
Abstract The biological carbon pump (BCP) is the mechanism by which ocean transports organic matter below mixed layer, exporting or sequestering it for years to millennia. Physical transport of dissolved and particulate carbon, sinking particles, transported diel seasonal vertical migrants are three main mechanisms BCP. In study active flux, seasonality almost unknown changes in productivity during annual cycle could promote differences this transport. Here, we show results a cruise...
Abstract Otoliths of actinopterygians are calcified structures playing a key role in hearing and equilibrium functions. To understand their morphological diversification, we quantified the shape otoliths both lateral dorsal view from 697 323 species, respectively, using geometric morphometrics. We then combined form (i.e. size shape) information with ecological data phylogenetically informed comparative methods to test our hypotheses. Initially, exploration morphospaces revealed that main...
The early life of most decapod crustaceans takes place in the water column as larvae before they settle benthic habitats. spatial and temporal variability settling larval stages offers valuable insights into potential recruitment natural populations. To explore this, we studied megalopa assemblages at various segments coastline on El Hierro Lanzarote islands, both within outside Marine Protected Areas (MPAs) each island. study spanned four consecutive oceanographic periods Canary Islands (NW...
Abstract Larval morphology in brachyuran crabs is an essential trait defining survival the planktonic environment. The present study describes (carapace and chelipeds) of megalopa larvae three different species ( Percnon gibbesi, Cronius ruber , Achelous hastatus ) using geometric morphometric analysis gma ). aim was to compare observed body patterns at interspecific intraspecific levels. results showed a marked distinction C. based on rostral region carapace cheliped length. We relate these...
Embryos (morula stage) of Atlantic cod, Gadus morhua L., were collected and subjected to air exposure for 2 min. followed by recovery at ambient conditions in the rearing container. Total immunoreactive cortisol transcription selected stress- apoptosis-related genes embryos determined before application stressor 0.5, 1 24 h post-exposure. There was no significant difference total levels fertilized eggs after handling stress. high expression level hsp70 sod significantly increased 0.5 The cat...

Slipper (Scyllaridae) and spiny (Palinuridae) lobsters show a complex life cycle with planktonic larval phase, named phyllosoma. This unique form within Achelata (Decapoda) is characterized by transparent dorsoventrally compressed body pair of antennae. conspicuous morphology has been attributed to adaptive specialization life. Early studies suggest that phyllosoma remained constant over the evolutionary history Achelata, while recent evidence points out large morphological changes...
The morphology of larvae is a key factor influencing their behaviour, performance and ultimately survival. There evidence indicating significant morphological variability among broods, that this may be related to the size or conditions mother. However, maternal influence not consistent across decapod crustaceans. Using 35 broods from different mothers crab Hemigrapsus takanoi collected in same locality inner Tokyo Bay at time, we tested hypothesis there positive relationship between mother...
Sturgeons are the most endangered species group and their wild populations continue to decrease. In this study, we apply intracytoplasmic sperm injection (ICSI), an assisted reproductive technology, for first time in critically sturgeons. Using various egg-sperm combinations performed different ICSI experiments with immobilized pre- or non-activated spermatozoa, single many, fresh cryopreserved. Then evaluated fertilization success as well paternity of resultant embryos larvae. Surprisingly,...
