Summary: Seed dispersal is a crucial mechanism for plant conservation, especially in tropical regions where most woody plant species rely on vertebrates to disperse their seeds through fruit consumption. With the aim of facilitating research on seed dispersal and seed predation in the Guianas, a database of fruit and seed traits and vertebrate-fruit interactions for tree and vertebrate species was compiled. The analysis revealed a taxonomic bias towards large-bodied vertebrates in the interaction data, with certain families of plants being overrepresented or underrepresented.

Summary: A study used a species distribution model to assess the habitat suitability of the amphibian pathogen Bd in the three Guianas in South America. The results showed that all three countries have substantial areas suitable for Bd growth, and the maximum temperature of the warmest month was identified as the top predictor for suitable Bd habitat.

Summary: The Maroni basin, which forms the border between Suriname and French Guiana, has sociocultural, geographical, and economic factors that contribute to the transmission of sexually transmitted infections and delays in diagnosis and treatment. This study aimed to describe the different sexually transmitted infections in the Maroni basin and gain a better understanding of the epidemiological situation. The findings suggest that sexually transmitted infections are more prevalent in the urban center of Saint Laurent du Maroni compared to the remote villages along the Maroni. The study emphasizes the need for a coordinated approach and improved diagnostic methods to reduce the burden of sexually transmitted infections in this region.

Summary: This study tested the efficiency of various single-marker species delimitation methods on leaf beetles and found that factors such as number of haplotypes, geographic distance, difficulty in species identification, and taxonomic rank can affect efficiency. Distance-based methods outperformed phylogenetic tree methods, and a higher number of haplotypes per species had a negative effect on delimitation efficiency. The presence of species that are difficult to identify also significantly decreased the efficiency of delimitation methods.

Summary: On the French Guiana-Suriname border, members of the same population groups engage in circular mobility, with their practices and identities influenced by traditional emic social distinctions, modern states' language ideologies, and emerging discourses in the urban context. The study shows that the border zone constitutes a separate sociolinguistic area, but multiple identifications co-exist among the Maroon population, leading to both similarities and sharp differences at various levels of language use and ideologies.

Summary: Two cases of brucellosis were reported in male patients from Brazil who were working as clandestine goldminers in French Guiana. The bacterial isolates represented a potential new species of Brucella. Medical practitioners in this region should be aware of these pathogens and the potential for human infection.

Summary: The study aimed to investigate the genetic diversity of Angiostrongylus cantonensis in Ecuador. The analysis revealed that all A. cantonensis isolates from different provinces in Ecuador were genetically identical and clustered with isolates from the USA and Asia. This suggests that the invasion of A. cantonensis in Ecuador may have occurred recently and originated from Asia through the USA. Further research should include samples from neighboring countries.

Summary: This paper presents a new species of Hydrobia from the brackish Moustos spring in Arkadia, Greece. Through examination of reproductive organs and molecular relationships, it is confirmed as a new genus and species. The origin of this species is related to the Messinian salinity crisis and speciation was promoted during the Pliocene flooding.

Summary: The study identified various paramyxoviruses in bats from French Guiana and revealed cross-infection of paramyxoviruses among different bat species. The results suggest a wide distribution of paramyxoviruses in Central to South America, highlighting the potential risk of cross-species transmission that warrants further investigation.

Summary: The article highlights the lack of genetic data for most fishery species in New Zealand, despite the potential of DNA markers to aid in stock delineation and provide insight. It discusses the global shift towards genomics in fisheries genetics and its implications for sustainable management of aquatic resources, emphasizing the need for a systematic and holistic approach to the use of genomics in New Zealand fisheries management.

Summary: The research found that in remote headwater streams in French Guiana, most fish species primarily rely on terrestrial carbon subsidies, with about 60% of species exclusively feeding on animal prey. The trophic positions were broadly distributed along the phylogeny and changed gradually within lineages.

Summary: This study compared the functional diversity of fish communities in shallow-water and deep-sea regions in New Zealand, finding equal overall diversity but differences in specific ecological functions. The deep-sea fish exhibited higher diversity in habitat utilization and locomotion traits, while showing lower diversity in feeding and life history traits compared to shallow-water fish.

Summary: The study investigated the genetic structure, genetic diversity, and demographic history of tarakihi fish in New Zealand, finding no clear genetic structure for the overall New Zealand area, indicating a panmictic genetic structure. The fish displayed high levels of genetic diversity and had experienced two population expansions likely due to repeated glacial cycles. Additionally, genetic differentiation was observed between two morphotypes of tarakihi fish, highlighting the importance of informed management for sustainable harvest.

Summary: By conducting whole-genome resequencing of tarakihi fish from New Zealand and Tasmania, the study found evidence of at least two separate reproductive stocks and a potential genomic cline driven by temperature gradients. Additionally, certain genes associated with environmental variables, particularly water temperature, were identified, providing crucial information for stock assessment and understanding adaptive variation in marine species.

Summary: Freshwater ecosystems are highly endangered, and understanding the impact of human activities on these ecosystems is crucial. This study used eDNA-based fish inventories and community-level modelling to identify the factors driving fish assembly and map spatial biodiversity. The results showed a mismatch between taxonomic and functional diversity, with environmental and anthropic factors playing a major role in functional assemblages. These findings have important implications for monitoring programs and the establishment of new survey sites to improve representativity of fish diversity.

Summary: During a recent collection expedition in the Rio Negro, Brazil, eight individuals of an unknown species were discovered, which were classified as a new species in the genus Rhadinoloricaria based on their combination of characteristics, including elongated papillae on the lower lip and unbranched barbelets on the margin of the lower lip. Morphological and phylogenetic analyses, along with osteological computed tomography scans, confirmed that these specimens represent a new species of Rhadinoloricaria.
