  • New records of the invasive marine crab Charybdis hellerii (Crustacea, Brachyura) in Cuba

    Diez, Yander L.; Catalá, Alejandro (2024)
    Revista de Investigaciones Marinas
    The brachyuran crab Charybdis hellerii is originally from the Pacific; nevertheless, the spe- cies has been introduced to tropical waters globally. Its initial sighting in the Western Atlan- tic was documented in 1990 based on specimens collected in Cuba in 1987. In this paper, we present findings of C. hellerii from two localities in eastern Cuba: Santiago de Cuba and Taco bays. Up to this point, the species has solely been documented in estuaries in Cuba, and it likely exists throughout the entire archipelago. Given its feeding behaviour and extensive distribution, encompassing areas within the National Park Alejandro de Humboldt, this species can be key in the formulation of conservation plans for Cuban marine ecosystems.
  • 2022-2023 ECOP Asia Report.

    Roman, Raphaël (UN Ocean Decade, Early Career Ocean Professionals (ECOP), 2023)
    The regional node of the ECOP Programme in Asia (hereinafter referred to as “ECOP Asia”) was informally established in June 2021, during the Virtual Early Career Ocean Professionals Day (V.ECOP Day). At the time, ECOP Asia was composed of a dozen volunteer members from countries across East, South and Southeast Asia, including Bangladesh, China, India, Indonesia, Japan, Malaysia, Philippines and the Republic of Korea. The core team met on a monthly basis with the aim of connecting interdisciplinary groups of ECOPs across the continent, and sharing knowledge and experience about the recently launched United Nations Decade of Ocean Science for Sustainable Development (2021-2030) (hereinafter referred to as the “UN Ocean Decade”). Members of the informal 2021 ECOP Asia group were particularly active and motivated to spread the word about ECOPs and the UN Ocean Decade. Among other contributions, they circulated the first pan-Asia ECOP survey in early Spring 2021 (with region- and country-specific results available in this report1), celebrated “World Oceans Day” on 8 June 2021 by sharing inspiring testimonials from ECOPs across India (video), made short awareness-raising interventions during online webinars and workshops, and moderated a Decade Action Incubator Session dedicated to ECOPs during the UN Decade Regional Kickoff Conference for the Western Pacific and its Adjacent Areas, a two-day conference co-sponsored by the Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) and its sub-commission for the Western Pacific (WESTPAC). The latter session provided perspectives on science communication, inviting speakers from different career stages and ocean sectors2 (video recording is available here). On November 2021, the IOC-UNESCO launched a call for individual consultants to support a variety of tasks related to the development of the regional dimensions of the ECOP Programme, seeking coordinators in Africa, Asia, Oceania and the Caribbean Small Island Developing States (SIDS)3. A regional consultant was subsequently hired for Asia in mid-December 2021 and has remained in this position since then. The hiring process coincided with the official launch of the ECOP Programme website, including dedicated web pages for the first three regional and national ECOP nodes: Africa, Asia and Canada4. By November 2022, a national node in Japan and regional hub in Central America were also established, followed closely by a new regional chapter in the Caribbean. Throughout the first half of 2023, another nine additional national nodes have emerged from all over the world, including in Brazil, Italy, Morocco, Niger, Nigeria, the Republic of Korea, Senegal, Togo and the United States. Several other ECOP chapters are waiting in the pipeline, currently building their own core teams, drafting concept notes, and engaging with their respective communities (e.g., Australia/New Zealand, Belgium, China, Europe, India, Liberia, Malaysia, Mexico, Mozambique, Spain and the United Kingdom). Extending from the Middle East all the way to Indonesia in Southeast Asia, and including the Russian Federation5, the ECOP Asia community grew significantly throughout 2022 and in the early months of 2023 (see section I). Figure 1 below provides a non-exhaustive list of 2022 activities and highlights that contributed to the development and expansion of ECOP Asia since the appointment of the regional consultant/coordinator. Table 1 lists more recent updates and achievements since November 2022, including ongoing work in 2023.
  • Assessing plastic pollution in Brazilian aquatic ecosystems:an integrated study of pollution in organisms and environments.

    Cardozo, Ana Lúcia Paz (Universidade Estadual de Maringá. Departamento de Biologia. Programa de Pós-Graduação em Ecologia de Ambientes Aquáticos Continentais., 2024)
    Plastics are pervasive contaminants worldwide, accumulating from the poles to the equator, spanning pristine environments to deep ocean basins.This workexplores how seasonal variations in a floodplain influence the ingestion of plastics by freshwater fish and systematically examines trends and gaps in Brazilian research related to plastic pollution.Additionally, the potential relationship between anthropogenic activities and the amounts of plastic found in Brazilian aquatic environmentswas investigated.Among the 23 fish species analyzed in the Upper Paraná River floodplain, nine were ingested plastics, and the particles were associated with fishingactivity and domestic waste. Seasonality played a crucial role in the amounts of plastic ingested by these species, with the highest number of particles recorded during the wet season. As for trends and gaps in Brazilian research on plastic pollution, a substantial number of publications related to marine environments, microplastics, and fishwas identified. Conversely, freshwater environments and invertebrates are underexplored.Considering the distribution of studies within Brazilian biomes, the Pantanaland Cerrado had the lowest number of publications—an alarming trend considering the significant rivers and basins they house.Finally, themodels were unable to find strong and significant correlations between the number of plastics and anthropogenic activities in Brazilian municipalities.The lack of significant relationships may be attributed to the limitations of our dataset, specificallydue to the low number of studies.Nevertheless, other factors influenced the quantities of plastic detected.In biotic samples, the number of ingested plastics was influenced by the animal group, with reptiles, birds, and fish being the most affected groups. For abiotic samples, the type of environment emerged as a significant factor.In sediment samples, the quantity of plastics was higher in estuarine and freshwater environments. In water samples, the quantity of plastics was higher exclusively in freshwater environments.The finds of this workcontribute to new research on plastic pollution in Brazilian aquatic environments, expanding theunderstanding of the dynamics of plastics in freshwater environments and their interaction with various organisms.
  • Ecological characteristic of hermit crabs in Lhokseumawe mangrove forest, Aceh, Indonesia

    Journal of Marine Studies
    The study was conducted between August and September of 2021 in order to determine the density, ecological index, distribution pattern, geographic distribution, environmental factors, and the relationship between hermit crabs and environmental factors. Hermit crabs were gathered using a quadratic transect and sample plots, while environmental variables were measured in situ. PCA and CCA multivariate statistics were used to determine the characteristics and correlation between hermit crabs and environmental factors. Hermit crabs were discovered to be comprised of two species (Clibanariuslongitarsus and C. infraspinatus) and one family (Diogenidae), with the highest density found in the C. longitarsus species (1.22 ± 0.57 – 4.68 3.53 ind/m2), diversity index is categorized as moderate (2.01), the geographical distribution is abundant (>80%), and environmental factors are categorized as good. In addition, Stations I and II have high DO, TOM, mangrove density, C. longitarsus, and C. infraspinatus parameters, whereas Station III has high salinity, pH, and temperature, with salinity, mangrove density, and TOM being the most influential parameters on hermit crab density.
