Changes in species diversity and abundance of the main components of the Black Sea pelagic community during the last decade Shiganova, TA; Kideys, AE; Gücü, Ali Cemal; Niermann, U; Khoroshilov, VS (1998-01-01) The changes in species diversity and abundance of ichthyo- and zooplankton in the northern (mainly in the north-eastern) and southern regions of the Black Sea were analysed prior to and after the Mnemioysis leidyi invasion. In addition, long-term changes in species diversity and abundance of gelatinous animals were briefly considered for understanding the extent of their influence on the pelagic community.
Changes in biodiversity of phytoplankton, zooplankton, fishes and macrobenthos in the Southern Caspian Sea after the invasion of the ctenophore Mnemiopsis Leidyi Roohi, Aboulghasem; Kıdeyş, Ahmet Erkan; Sajjadi, Ameneh; Hashemian, Abdolla; Pourgholam, Reza; Fazli, Hasan; Khanari, Ali Ganjian; Eker-Develi, Elif (2010-07-01) Monitoring for 6 years (2001-2006) showed that the population explosion of the alien ctenophore Mnemiopsis leidyi in the southern Caspian Sea coincided with a decline in the abundance and species number of mesozooplankton. While this decline appeared to have reduced the nourishment of sprat (also known as kilka), it seemed to have affected phytoplankton favorably mainly due to the decrease in grazing pressure. During 2001-2002, when M. leidyi abundance and biomass were at their highest levels, abundance of ...
Changes in functional composition and diversity of waterbirds: The roles of water level and submerged macrophytes Özgencil, İbrahim Kaan; Beklioğlu, Meryem; Özkan, Korhan (2021-01-18)
Changes in functional composition and diversity of waterbirds: The roles of water level and submerged macrophytes Özgencil, İbrahim Kaan; Beklioğlu, Meryem; Özkan, Korhan; TAVŞANOĞLU, ÇAĞATAY; Fattorini, Niccolo (2020-06-02) Water level and submerged macrophytes are critical players for the functioning of shallow lake ecosystems; understanding how waterbird communities respond to changes in both can have important implications for conservation and management. Here, we evaluated the effects of changes in water level and submerged macrophyte status on wintering waterbird community size, functional group abundances, functional diversity (FD), and community assembly by using a dataset compiled over 50 years.
Changes in plant-herbivore network structure and robustness along land-use intensity gradients in grasslands and forests Neff, Felix; Braendle, Martin; Ambarlı, Didem; Ammer, Christian; Bauhus, Juergen; Boch, Steffen; Hoelzel, Norbert; Klaus, Valentin H.; Kleinebecker, Till; Prati, Daniel; Schall, Peter; Schaefer, Deborah; Schulze, Ernst-Detlef; Seibold, Sebastian; Simons, Nadja K.; Weisser, Wolfgang W.; Pellissier, Loic; Gossner, Martin M. (2021-05-01) Land-use intensification poses major threats to biodiversity, such as to insect herbivore communities. The stability of these communities depends on interactions linking herbivores and host plants. How interaction network structure begets robustness, and thus stability, in different ecosystems and how network structure and robustness are altered along land-use intensity gradients are unclear. We analyzed plant-herbivore networks based on literature-derived interactions and long-term sampling from 289 grassl...
