Summary: This study reveals the presence of four genetic lineages within the Neotropical catfish genus Kronichthys, with three lineages within Kronichthys heylandi along the coast from Rio de Janeiro to southern Sao Paulo and a single lineage encompassing both the nominal species Kronichthys lacerta and Kronichthys subteres. Morphological data show differences in tooth number between the species, suggesting a potential basis for species delimitation in Kronichthys. Headwater captures and connections of paleodrainages due to sea-level fluctuations are identified as key biogeographic processes promoting species diversification and lineage dispersal of Kronichthys in the Atlantic coastal range of Brazil.

Summary: The polychaete family Syllidae has been neglected in the Bermuda Archipelago, despite its dominance in marine benthic ecosystems. To fill this knowledge gap, a comprehensive analysis of Bermudan Syllidae was conducted, combining morphological and molecular data. Five new species were identified and their phylogenetic positions established, along with proposing reorganization of Opisthosyllis and Syllis based on molecular characters.

Summary: A new genus and species of trimorphic Coralliidae was discovered during bathyal samplings by the Spanish Institute of Oceanography. The new species has unique growth morphology and molecular characteristics. Despite the already rich bathyal fauna of the Bay of Biscay and nearby areas, new species continue to be discovered during sampling.

Summary: The study aimed to isolate, identify, and report the species richness of Trichoderma species in the soil of different regions of Pernambuco, Brazil. DNA sequences of 56 isolates were analyzed, revealing two sections, Trichoderma (35 isolates) and Pachybasidium (21 isolates), and a total of nine species, including possible new species. The findings indicate the potential for agricultural applications due to the diversity of Trichoderma species in Pernambuco soils.

Summary: In this paper, the discovery of hidden biodiversity of the genus Dendronotus in the bathyal areas of the North Pacific is reported. Different scenarios of Dendronotus expansion to deeper waters are tested using an integrative analysis based on morphological and molecular data. The results reveal the presence of seven new species, with five of them being described in this study. Phylogenetic reconstructions show that these new species belong to different lineages of Dendronotus, and ancestral area reconstruction indicates multiple independent invasions of deep waters.

Summary: Understanding the current biodiversity of our planet is a challenge due to habitat destruction exceeding species description rates. South America is home to a significant number of parrot species, with the feather mites associated with them being poorly studied. In this study, three new species of feather mites belonging to the genus Lopharalichus were identified in Brazilian parrots, adding to the knowledge of this genus.

Summary: The morphology and genetic characteristics of two new freshwater euplotid ciliates, Euplotes chongmingensis and E. paramieti, isolated from Shanghai, China, were investigated. These new species improve the knowledge of biodiversity and enrich the database of euplotids, providing a reliable reference for environmental monitoring and resource investigations.

Summary: In this study, pollen morphology of 14 mimosaceous species belonging to five genera was analyzed using light microscopy (LM) and scanning electron microscopy (SEM). Qualitative and quantitative characters were used to determine palynological features. The study identified various shapes of pollen grains and different exine sculpturing patterns, providing important morpho-palynological characters for identification and validation of related taxa within Mimosaceae family.

Summary: Trapania is the second largest genus in the family Goniodorididae, mainly found in the Indo-Pacific waters. However, the taxonomic characteristics of Trapania species have been uncertain, and this study performs a morphological and molecular revision of the East Atlantic-Mediterranean species, suggesting an overestimation of species richness in this region.

Summary: This study examines the bryozoan fauna from sediment outcrops in Estonia and NW Russia. A total of 18 species belonging to different orders are identified, including two new species. The findings reveal close relations between these bryozoans and other localities in the Baltic region, with some connections to the Ordovician of China as well. The bryozoans in this area have adapted to shallow to moderately deep environments with moderate water energy and a relatively high level of sedimentation.

Summary: Research in artificial habitats in the Southwestern Atlantic revealed that fouling bryozoan communities are diverse, with no significant differences between commercial and recreational sites. However, faunal assemblages vary significantly along Brazilian coastal stretches, influenced by environmental conditions like salinity and temperature.

Summary: The study showed significant differences in observed OTUs among regions and identified three distinct groups based on presence/absence beta diversity analysis, with one group from the Azores, a second from Madeira, and a third from mainland Portugal, Selvagens, and the Canaries. These results are mainly driven by large-scale oceanographic processes in the study region, particularly the North Atlantic Subtropical Gyre and the Canary Current. The feasibility of using microbiome as a model study to understand biogeographic and evolutionary processes in marine species with high dispersal potential was suggested by the findings.

Summary: This study investigated the morphological and genetic differentiation of G. cf. caeciliae specimens collected from several seamounts in the Central Atlantic. Three distinct species, including a new species, were identified through combined morphological and molecular analyses. The study also revealed morphological features and discussed their functions, and demonstrated a high dispersal potential for the new species through population analysis.

Summary: Harbours, as highly modified habitats, are hotspots for non-indigenous species (NIS) and can facilitate invasive processes. However, predation can also play a role in controlling NIS. This study found that predation increased the abundance of NIS, specifically Watersipora subatra, in estuarine marinas but had no effect in the coastal marina. The findings suggest that predation can increase the risk of NIS invasion and highlight the importance of understanding the effects of biotic interactions in coastal artificial habitats.
