Summary: The study found that there is a rare hump-shaped latitudinal diversity gradient among marine organisms along the Southeastern Pacific coast, with species richness peaking at around 42 degrees south and declining towards the northern and southern areas. There is a significant increase in phylogenetic conservatism and species richness towards the southern region, while pairwise distance variation shows the opposite trend. This suggests that evolutionary processes play a major role in shaping the latitudinal diversity gradient in this region.

Summary: Marine protists have traditionally been considered low in diversity and widespread, but recent studies have shown the presence of cryptic species complexes. Overcoming sampling and methodological limitations, global metabarcoding data analysis reveals geographic and ecological differentiation driving speciation among marine protists.

Summary: This study describes three new species of Platynereis from Taiwan, increasing our understanding of the diversity of these worms in the tropical Western Pacific. The new species Platynereis hemeiensis is similar to other species in terms of lacking certain features in adults, but differs in various morphological characteristics. Platynereis jihueiensis and Platynereis shihmenensis are similar to Platynereis bicanaliculata but differ in the presence or absence of pectinate paragnaths in specific areas. A key for identifying Platynereis species from East Asia is provided.

Summary: This study analyzed a dataset of 7261 marine megafauna to investigate the influence of their foraging strategies on solid waste ingestion along the Brazilian coast. Results showed that 1240 individuals ingested solid waste, with over 55% ingesting plastic. Sea turtles were the most affected, while cetaceans had the lowest frequency of ingestion. Certain characteristics, such as regurgitation in seabirds and echolocation in cetaceans, may mitigate the negative effects of solid waste ingestion. This study provides a valuable baseline for solid waste management and marine megafauna conservation efforts.

Summary: Scientific expeditions in the 19th century collected valuable interdisciplinary data and samples, which are now held in museums worldwide and provide unique opportunities for research. This study utilized samples from Brazil's coast to investigate the Marine Reservoir Effect (MRE) and revealed variability in C-14 concentration, with implications for environmental and archaeological studies in the region. The results also contribute to the validation of C-14 simulations in numerical models, highlighting the importance of natural history collections beyond biodiversity preservation.

Summary: By reconstructing the transcriptome-based phylogeny of 19 diploid Ephedra species, the evolutionary history of the gymnosperm genus Ephedra was investigated. The results revealed that Ephedra originated from Mediterranean species and split into three clades: American species, E. rhytidosperma, and other Asian species. Reticulate evolution was found to be common in Ephedra, and the genus likely originated in the late Cretaceous along the Tethys coast.

Summary: This study used bioacoustical analysis to investigate cryptic species within the humbug damselfish complex. By recording chase and courtship sounds, it was found that courtship sounds were more consistent and could potentially help discriminate cryptic species in Teleosts. Acoustic features and genetic data variations were observed between different populations, supporting the differentiation of distinct populations within the complex.

Summary: The study reveals the diversification process within a beetle species adapted to the soil environment. Through molecular phylogenetics, population genomics, and morphometric analysis, it was found that the species consists of at least seven lineages, suggesting the presence of a cryptic species complex.

Summary: This study investigated the single and combined toxic effects of metals cadmium and copper on the macrofaunal bioturbation potential of the polychaete Perinereis aibuhitensis. It was found that the transportation capacity of P. aibuhitensis was negatively correlated with Cd concentration, while Cu stress promoted downward transportation. There was a certain synergistic effect between cadmium and copper, and the toxicity effects were influenced by metal concentration and stress duration.

Summary: The study found that the response rate of Tropical Screech-Owls to playback was 83.4%, mainly responding to an undescribed variation of their recorded A-song. It was also discovered that wind speed (especially wind bursts) had a negative impact on the response rate, while higher cloud cover and lower ambient light significantly increased owl responses.

Summary: Fireflies are facing threats from deforestation, urbanisation, and light pollution, with the latter having a significant impact on their unique communication methods. Light pollution is increasing rapidly in extent and intensity, surpassing urbanisation and deforestation rates. Protected areas can buffer the effects of urbanisation and deforestation, but are unable to stop the spread of light pollution, which poses a serious threat to firefly populations, especially in the Atlantic Forest.

Summary: The efficacy of Marine Protected Areas (MPAs) in Brazil, particularly for elasmobranch species, is at risk due to anthropogenic pressures and a lack of ecological research. Efforts to address these issues are underway, but the effectiveness of MPAs in the region needs to be carefully monitored and enhanced to ensure the conservation of marine species.

Summary: The spatial and temporal variability in rocky shore assemblages at multiple scales in Ilha Grande Bay, southeastern Brazil, is driven by natural factors and anthropogenic disturbances. The study found that substrate rugosity, rocky shore extension, water movement, percentage of deforested land area, and distance to urban center were the environmental variables that most explained spatial patterns of the assemblages. Patterns of horizontal variation were not fully consistent between depths, indicating the complexity of factors driving variability in rocky subtidal assemblages.

Summary: Agromyzidae is a cosmopolitan family of leaf-miner flies, with Liriomyza species causing significant damage to crops. This study investigated the impact of climatic factors, seasonality, and parasitoid abundance on leaf-miner infestation in Northeastern Brazil. Climate had different effects on leaf-miner populations in different crops, with larval abundances higher during the dry season and parasitoid abundance following the increase in mining larvae.
