    Bomb signals in old Antarctic brachiopods (1996)

    Notes: [Auszug] SIR - Skeletal check-marks are commonly used to assess the age and growth of organisms. They are usually assumed to be formed annually. By using radiocarbon bomb signals to calibrate growth checks in shells of Antarctic brachiopods, we show that they were laid down with a sub-biennial periodicity. ...

    Stable isotopes prove shell growth bands in the Antarctic bivalve Laternula elliptica to be formed annually (1997)
    Springer
    Polar biology 17 (1997), S. 465-468 
    Details
    ISSN: 1432-2056
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Growth marks in calcareous shells or skeleton parts of benthic invertebrates are often assumed to be formed annually and hence are used for ageing purposes. For some Antarctic species this assumption has been validated by tagging experiments or direct monitoring of growth throughout the year. Here we use the record of stable isotope ratios (δ18O and δ13C) deposited in shell carbonate of Laternula elliptica from King George Island to demonstrate that shell growth bands are formed annually in this species.

    A seminal study of the dynamics of a mudskipper (Periophthalmus papilio) population in the Cross River, Nigeria (1996)

    ISSN: 1573-5125
    Keywords: Population dynamics ; mudskipper ; Periophthalmus papilio ; Cross River ; Nigeria

    Topics: Biology
    Notes: Abstract A seminal study was conducted in which the population dynamics (growth, mortality and recruitment) of the mudskipper (Periophthalmus papilio) in the Cross River, Nigeria, was elucidated for the first time using length frequency data and the ELEFAN software. The allometric relationship was: Weight=0.012(Length)2.940, n=415, r2=0.939, P 〈0.0005. The seasonalized Von Bertalanffy growth parameters were L∞=19.39 cm, K=0.51 y−1, C=0.3, and WP=0.4. The instantaneous total mortality coefficient Z was 2.208 y−1 while the instantaneous natural mortality coefficient was 1.341 y−1. The instantaneous fishing mortality coefficient of 0.867 y−1 yielded the expectedly low exploitation rate E of 0.393. Our estimate shows that the species could reach an average maximum life span of about 6 years in the Cross River system. These results are used in quantitative elucidation of the state of exploitation of the population and will serve as input for the proper and scientific management of the fish resource.

    Climate change disrupts core habitats of marine species (2023)
    Wiley
    Details
    Publication Date: 2024-02-07
    Description: Driven by climate change, marine biodiversity is undergoing a phase of rapid change that has proven to be even faster than changes observed in terrestrial ecosystems. Understanding how these changes in species composition will affect future marine life is crucial for conservation management, especially due to increasing demands for marine natural resources. Here, we analyse predictions of a multiparameter habitat suitability model covering the global projected ranges of 〉33,500 marine species from climate model projections under three CO2 emission scenarios (RCP2.6, RCP4.5, RCP8.5) up to the year 2100. Our results show that the core habitat area will decline for many species, resulting in a net loss of 50% of the core habitat area for almost half of all marine species in 2100 under the high-emission scenario RCP8.5. As an additional consequence of the continuing distributional reorganization of marine life, gaps around the equator will appear for 8% (RCP2.6), 24% (RCP4.5), and 88% (RCP8.5) of marine species with cross-equatorial ranges. For many more species, continuous distributional ranges will be disrupted, thus reducing effective population size. In addition, high invasion rates in higher latitudes and polar regions will lead to substantial changes in the ecosystem and food web structure, particularly regarding the introduction of new predators. Overall, our study highlights that the degree of spatial and structural reorganization of marine life with ensued consequences for ecosystem functionality and conservation efforts will critically depend on the realized greenhouse gas emission pathway.

    Semi-quantitative records of benthic taxa from trawl samples taken in the wider Weddell Sea (Antarctica) during POLARSTERN cruises ANT VII/4, ANT IX/3, ANT XIII/3, ANT XV/3 and ANT XXI/2 between 1989 and 2004 (2020)

    Details
    Publication Date: 2023-07-10
    Description: The dataset comprises a total of 9,540 records of semi-quantitative data for 53 benthic invertebrate taxa and fish from 180 trawl samples (Agassiz trawl, bottom trawl, Rauschert dredge, benthopelagic trawl). The semi-quantitative data represent four categories regarding the frequency of occurrence of the benthic taxa (i.e. 0 = absent, 1 = rare, 2 = common and 3 = very common). The dataset was collected on the shelf and slope of the eastern Weddell Sea and Lazarev Sea, near Bouvet Island and the region at the north western tip of the Antarctic Peninsula (depth range: 64 - 2334 m) between 1989 and 2004 onboard "Polarstern". Cruises ANT VII/4 (1989), ANT IX/3 (1990/91), ANT XIII/3 (1996), ANT XV/3 (1998) and ANT XXI/2 (2003/2004) contributed to the data collection.
